Microsoft SC-300 Practice Test 8

Question 70

An organization wants only approved sponsors and administrators to invite external guests instead of allowing ordinary users to invite anyone. The proposed change is: Configure External collaboration invitation restrictions and delegate supported Guest Inviter privileges to approved sponsors. After applying the intended configuration, which observation most directly proves that the required behavior works?

  1. Check the B2B sign-in's Conditional Access details to confirm an eligible home-tenant MFA claim satisfied the resource requirement.
  2. Attempt an invitation as an ordinary employee and as an approved Guest Inviter, checking the different results.
  3. Have the partner redeem the invite and confirm the intended guest identity can open only the authorized resource.
  4. Test an employee reaching an approved external app and an unapproved external tenant app.

Explanation

Correct Answer

B:

Attempt an invitation as an ordinary employee and as an approved Guest Inviter, checking the different results. This directly tests the effective outcome, not merely that a configuration exists. It establishes whether the intended change works: configure External collaboration invitation restrictions and delegate supported Guest Inviter privileges to approved sponsors. Failure would be evident in this case: employees outside the sponsor group can invite arbitrary external contacts.

Incorrect Answers

A:

The proposed observation checks the different trust external mfa claim scenario. Even a successful test would not establish the requested outcome here: attempt an invitation as an ordinary employee and as an approved Guest Inviter, checking the different results.

C:

The proposed observation checks the different b2b guest invitation redemption scenario. Even a successful test would not establish the requested outcome here: attempt an invitation as an ordinary employee and as an approved Guest Inviter, checking the different results.

D:

The proposed observation checks the different outbound cross-tenant restriction scenario. Even a successful test would not establish the requested outcome here: attempt an invitation as an ordinary employee and as an approved Guest Inviter, checking the different results.

Question 71

Employees outside the sponsor group can invite arbitrary external contacts. Which root cause best explains the described result rather than merely treating its symptoms?

  1. The resource tenant has not enabled an appropriate inbound trust for that partner's MFA claim.
  2. The target tenant has not allowed inbound user synchronization from that partner tenant.
  3. The federation trust still contains the previous signing certificate or metadata.
  4. The tenant's external collaboration invitation policy still permits ordinary users to invite guests.

Explanation

Correct Answer

D:

The tenant's external collaboration invitation policy still permits ordinary users to invite guests. This is the causal explanation of the observed behavior: employees outside the sponsor group can invite arbitrary external contacts. Address the underlying mechanism with: configure External collaboration invitation restrictions and delegate supported Guest Inviter privileges to approved sponsors. Then confirm: attempt an invitation as an ordinary employee and as an approved Guest Inviter, checking the different results.

Incorrect Answers

A:

This diagnosis fits a separate trust external mfa claim incident: A partner user is challenged again for MFA despite performing it in the home tenant. It does not explain this case's observed failure; the tenant's external collaboration invitation policy still permits ordinary users to invite guests.

B:

This diagnosis fits a separate cross-tenant synchronization permission incident: A source-tenant synchronization job fails before creating users even though outbound access is permitted. It does not explain this case's observed failure; the tenant's external collaboration invitation policy still permits ordinary users to invite guests.

C:

This diagnosis fits a separate federated external identity provider incident: External users get an invalid-signature result after the IdP rotated its signing certificate. It does not explain this case's observed failure; the tenant's external collaboration invitation policy still permits ordinary users to invite guests.

Question 72

An organization wants only approved sponsors and administrators to invite external guests instead of allowing ordinary users to invite anyone. The initial implementation works. Which continuing control most directly prevents the same failure or drift from recurring?

  1. Audit invitations and sponsorship ownership while preserving required approved collaboration paths.
  2. Review guest owners, invitations and granted resource scopes at the end of each project.
  3. Limit MFA trust to verified partner tenants and audit sign-in outcomes before expanding trust.
  4. Scope synchronization to approved users and monitor deprovisioning when source assignments are removed.

Explanation

Correct Answer

A:

Audit invitations and sponsorship ownership while preserving required approved collaboration paths. This reduces future drift after the initial control is deployed: configure External collaboration invitation restrictions and delegate supported Guest Inviter privileges to approved sponsors. Recheck the actual behavior with: attempt an invitation as an ordinary employee and as an approved Guest Inviter, checking the different results.

Incorrect Answers

B:

This control manages future b2b guest invitation redemption drift, but it does not reduce the continuing exposure in the described external collaboration invitation roles case. The correct safeguard is: audit invitations and sponsorship ownership while preserving required approved collaboration paths.

C:

This control manages future trust external mfa claim drift, but it does not reduce the continuing exposure in the described external collaboration invitation roles case. The correct safeguard is: audit invitations and sponsorship ownership while preserving required approved collaboration paths.

D:

This control manages future cross-tenant synchronization permission drift, but it does not reduce the continuing exposure in the described external collaboration invitation roles case. The correct safeguard is: audit invitations and sponsorship ownership while preserving required approved collaboration paths.

Question 73

A supplier's users must access one enterprise app in the resource tenant, while all unrelated supplier users and apps remain blocked. Which proposed configuration or implementation directly meets the stated requirement?

  1. Configure an outbound cross-tenant access policy for the permitted partner identities and applications.
  2. Configure an organization-specific inbound B2B cross-tenant access rule scoping supplier users/groups and the target app.
  3. Configure the external organization's inbound cross-tenant trust settings to accept the supported home-tenant MFA claim.
  4. Enable target-tenant inbound cross-tenant synchronization permissions and configure an authorized source-tenant provisioning job.

Explanation

Correct Answer

B:

Configure an organization-specific inbound B2B cross-tenant access rule scoping supplier users/groups and the target app. The solution acts at the intended identity, policy or application scope. A successful result is testable: test one eligible supplier user and one excluded identity against the intended app, inspecting cross-tenant decision details. The competing configuration error is: the resource tenant's inbound cross-tenant application filter does not include the required app.

Incorrect Answers

A:

That action implements the separate outbound cross-tenant restriction decision. It is appropriate when employees are allowed to collaborate with a verified audit partner but must not access unapproved partner cloud applications. The present case instead requires the specific inbound cross-tenant application scope change: configure an organization-specific inbound B2B cross-tenant access rule scoping supplier users/groups and the target app.

C:

That action implements the separate trust external mfa claim decision. It is appropriate when a trusted external organization's staff already satisfy strong MFA in their home tenant; the resource tenant wants Conditional Access to honor that claim for B2B sessions. The present case instead requires the specific inbound cross-tenant application scope change: configure an organization-specific inbound B2B cross-tenant access rule scoping supplier users/groups and the target app.

D:

That action implements the separate cross-tenant synchronization permission decision. It is appropriate when a group wants to provision staff identities from its source tenant into a subsidiary target tenant without relying on individual manual B2B invitations. The present case instead requires the specific inbound cross-tenant application scope change: configure an organization-specific inbound B2B cross-tenant access rule scoping supplier users/groups and the target app.

Question 74

A supplier's users must access one enterprise app in the resource tenant, while all unrelated supplier users and apps remain blocked. The proposed change is: Configure an organization-specific inbound B2B cross-tenant access rule scoping supplier users/groups and the target app. After applying the intended configuration, which observation most directly proves that the required behavior works?

  1. Test an employee reaching an approved external app and an unapproved external tenant app.
  2. Have the partner redeem the invite and confirm the intended guest identity can open only the authorized resource.
  3. Check the B2B sign-in's Conditional Access details to confirm an eligible home-tenant MFA claim satisfied the resource requirement.
  4. Test one eligible supplier user and one excluded identity against the intended app, inspecting cross-tenant decision details.

Explanation

Correct Answer

D:

Test one eligible supplier user and one excluded identity against the intended app, inspecting cross-tenant decision details. This directly tests the effective outcome, not merely that a configuration exists. It establishes whether the intended change works: configure an organization-specific inbound B2B cross-tenant access rule scoping supplier users/groups and the target app. Failure would be evident in this case: an authorized supplier employee is blocked because inbound access settings for that organization exclude the application.

Incorrect Answers

A:

The proposed observation checks the different outbound cross-tenant restriction scenario. Even a successful test would not establish the requested outcome here: test one eligible supplier user and one excluded identity against the intended app, inspecting cross-tenant decision details.

B:

The proposed observation checks the different b2b guest invitation redemption scenario. Even a successful test would not establish the requested outcome here: test one eligible supplier user and one excluded identity against the intended app, inspecting cross-tenant decision details.

C:

The proposed observation checks the different trust external mfa claim scenario. Even a successful test would not establish the requested outcome here: test one eligible supplier user and one excluded identity against the intended app, inspecting cross-tenant decision details.

Question 75

An authorized supplier employee is blocked because inbound access settings for that organization exclude the application. Which root cause best explains the described result rather than merely treating its symptoms?

  1. The target tenant has not allowed inbound user synchronization from that partner tenant.
  2. The home tenant's outbound cross-tenant settings independently block that destination.
  3. The resource tenant's inbound cross-tenant application filter does not include the required app.
  4. The resource tenant has not enabled an appropriate inbound trust for that partner's MFA claim.

Explanation

Correct Answer

C:

The resource tenant's inbound cross-tenant application filter does not include the required app. This is the causal explanation of the observed behavior: an authorized supplier employee is blocked because inbound access settings for that organization exclude the application. Address the underlying mechanism with: configure an organization-specific inbound B2B cross-tenant access rule scoping supplier users/groups and the target app. Then confirm: test one eligible supplier user and one excluded identity against the intended app, inspecting cross-tenant decision details.

Incorrect Answers

A:

This diagnosis fits a separate cross-tenant synchronization permission incident: A source-tenant synchronization job fails before creating users even though outbound access is permitted. It does not explain this case's observed failure; the resource tenant's inbound cross-tenant application filter does not include the required app.

B:

This diagnosis fits a separate outbound cross-tenant restriction incident: An employee's outbound sign-in to a partner app fails even though the partner resource tenant permits inbound access. It does not explain this case's observed failure; the resource tenant's inbound cross-tenant application filter does not include the required app.

D:

This diagnosis fits a separate trust external mfa claim incident: A partner user is challenged again for MFA despite performing it in the home tenant. It does not explain this case's observed failure; the resource tenant's inbound cross-tenant application filter does not include the required app.

Question 76

A supplier's users must access one enterprise app in the resource tenant, while all unrelated supplier users and apps remain blocked. Select TWO complementary decisions: the correct technical implementation and the ongoing preventive control. Evidence-only tests and controls for a different scenario are not substitutes for those two responsibilities.

  1. Manage partner-specific inbound allowlists with change control rather than opening all tenant applications.
  2. Configure the external organization's inbound cross-tenant trust settings to accept the supported home-tenant MFA claim.
  3. Enable target-tenant inbound cross-tenant synchronization permissions and configure an authorized source-tenant provisioning job.
  4. Configure an organization-specific inbound B2B cross-tenant access rule scoping supplier users/groups and the target app.
  5. Allow every external user in the supplier tenant to access all internal applications rather than keeping the reviewed single-app inbound allowlist.

Explanation

Correct Answers

A:

Manage partner-specific inbound allowlists with change control rather than opening all tenant applications. This reduces future drift after the initial control is deployed: configure an organization-specific inbound B2B cross-tenant access rule scoping supplier users/groups and the target app. Recheck the actual behavior with: test one eligible supplier user and one excluded identity against the intended app, inspecting cross-tenant decision details.

D:

Configure an organization-specific inbound B2B cross-tenant access rule scoping supplier users/groups and the target app. The solution acts at the intended identity, policy or application scope. A successful result is testable: test one eligible supplier user and one excluded identity against the intended app, inspecting cross-tenant decision details. The competing configuration error is: the resource tenant's inbound cross-tenant application filter does not include the required app.

Incorrect Answers

B:

That action implements the separate trust external mfa claim decision. It is appropriate when a trusted external organization's staff already satisfy strong MFA in their home tenant; the resource tenant wants Conditional Access to honor that claim for B2B sessions. The present case instead requires the specific inbound cross-tenant application scope change: configure an organization-specific inbound B2B cross-tenant access rule scoping supplier users/groups and the target app.

C:

That action implements the separate cross-tenant synchronization permission decision. It is appropriate when a group wants to provision staff identities from its source tenant into a subsidiary target tenant without relying on individual manual B2B invitations. The present case instead requires the specific inbound cross-tenant application scope change: configure an organization-specific inbound B2B cross-tenant access rule scoping supplier users/groups and the target app.

E:

Opening every internal application to all partner identities defeats the requested supplier-only app boundary and creates broad B2B exposure.

Question 77

Employees are allowed to collaborate with a verified audit partner but must not access unapproved partner cloud applications. Which proposed configuration or implementation directly meets the stated requirement?

  1. Configure an outbound cross-tenant access policy for the permitted partner identities and applications.
  2. Invite the partner as a B2B collaboration guest and grant only the necessary site and app access.
  3. Enable target-tenant inbound cross-tenant synchronization permissions and configure an authorized source-tenant provisioning job.
  4. Configure the external organization's inbound cross-tenant trust settings to accept the supported home-tenant MFA claim.

Explanation

Correct Answer

A:

Configure an outbound cross-tenant access policy for the permitted partner identities and applications. The solution acts at the intended identity, policy or application scope. A successful result is testable: test an employee reaching an approved external app and an unapproved external tenant app. The competing configuration error is: the home tenant's outbound cross-tenant settings independently block that destination.

Incorrect Answers

B:

That action implements the separate b2b guest invitation redemption decision. It is appropriate when a project manager needs a partner to access one SharePoint collaboration site with their existing home organization identity. The present case instead requires the specific outbound cross-tenant restriction change: configure an outbound cross-tenant access policy for the permitted partner identities and applications.

C:

That action implements the separate cross-tenant synchronization permission decision. It is appropriate when a group wants to provision staff identities from its source tenant into a subsidiary target tenant without relying on individual manual B2B invitations. The present case instead requires the specific outbound cross-tenant restriction change: configure an outbound cross-tenant access policy for the permitted partner identities and applications.

D:

That action implements the separate trust external mfa claim decision. It is appropriate when a trusted external organization's staff already satisfy strong MFA in their home tenant; the resource tenant wants Conditional Access to honor that claim for B2B sessions. The present case instead requires the specific outbound cross-tenant restriction change: configure an outbound cross-tenant access policy for the permitted partner identities and applications.

Question 78

Employees are allowed to collaborate with a verified audit partner but must not access unapproved partner cloud applications. The proposed change is: Configure an outbound cross-tenant access policy for the permitted partner identities and applications. After applying the intended configuration, which observation most directly proves that the required behavior works?

  1. Test an employee reaching an approved external app and an unapproved external tenant app.
  2. Attempt an invitation as an ordinary employee and as an approved Guest Inviter, checking the different results.
  3. Test one eligible supplier user and one excluded identity against the intended app, inspecting cross-tenant decision details.
  4. Inspect a scoped test user in the target tenant and verify the provisioning log records the expected lifecycle action.

Explanation

Correct Answer

A:

Test an employee reaching an approved external app and an unapproved external tenant app. This directly tests the effective outcome, not merely that a configuration exists. It establishes whether the intended change works: configure an outbound cross-tenant access policy for the permitted partner identities and applications. Failure would be evident in this case: an employee's outbound sign-in to a partner app fails even though the partner resource tenant permits inbound access.

Incorrect Answers

B:

The proposed observation checks the different external collaboration invitation roles scenario. Even a successful test would not establish the requested outcome here: test an employee reaching an approved external app and an unapproved external tenant app.

C:

The proposed observation checks the different inbound cross-tenant application scope scenario. Even a successful test would not establish the requested outcome here: test an employee reaching an approved external app and an unapproved external tenant app.

D:

The proposed observation checks the different cross-tenant synchronization permission scenario. Even a successful test would not establish the requested outcome here: test an employee reaching an approved external app and an unapproved external tenant app.

Question 79

An employee's outbound sign-in to a partner app fails even though the partner resource tenant permits inbound access. Which root cause best explains the described result rather than merely treating its symptoms?

  1. Guest object creation did not by itself grant the SharePoint resource entitlement or satisfy inbound policies.
  2. The resource tenant's inbound cross-tenant application filter does not include the required app.
  3. The home tenant's outbound cross-tenant settings independently block that destination.
  4. The target tenant has not allowed inbound user synchronization from that partner tenant.

Explanation

Correct Answer

C:

The home tenant's outbound cross-tenant settings independently block that destination. This is the causal explanation of the observed behavior: an employee's outbound sign-in to a partner app fails even though the partner resource tenant permits inbound access. Address the underlying mechanism with: configure an outbound cross-tenant access policy for the permitted partner identities and applications. Then confirm: test an employee reaching an approved external app and an unapproved external tenant app.

Incorrect Answers

A:

This diagnosis fits a separate b2b guest invitation redemption incident: A guest account exists in the tenant but the partner still receives an access-denied result for the site. It does not explain this case's observed failure; the home tenant's outbound cross-tenant settings independently block that destination.

B:

This diagnosis fits a separate inbound cross-tenant application scope incident: An authorized supplier employee is blocked because inbound access settings for that organization exclude the application. It does not explain this case's observed failure; the home tenant's outbound cross-tenant settings independently block that destination.

D:

This diagnosis fits a separate cross-tenant synchronization permission incident: A source-tenant synchronization job fails before creating users even though outbound access is permitted. It does not explain this case's observed failure; the home tenant's outbound cross-tenant settings independently block that destination.

Question 80

Employees are allowed to collaborate with a verified audit partner but must not access unapproved partner cloud applications. The initial implementation works. Which continuing control most directly prevents the same failure or drift from recurring?

  1. Manage partner-specific inbound allowlists with change control rather than opening all tenant applications.
  2. Test both source outbound and resource inbound policy when diagnosing cross-tenant failures.
  3. Limit MFA trust to verified partner tenants and audit sign-in outcomes before expanding trust.
  4. Review guest owners, invitations and granted resource scopes at the end of each project.

Explanation

Correct Answer

B:

Test both source outbound and resource inbound policy when diagnosing cross-tenant failures. This reduces future drift after the initial control is deployed: configure an outbound cross-tenant access policy for the permitted partner identities and applications. Recheck the actual behavior with: test an employee reaching an approved external app and an unapproved external tenant app.

Incorrect Answers

A:

This control manages future inbound cross-tenant application scope drift, but it does not reduce the continuing exposure in the described outbound cross-tenant restriction case. The correct safeguard is: test both source outbound and resource inbound policy when diagnosing cross-tenant failures.

C:

This control manages future trust external mfa claim drift, but it does not reduce the continuing exposure in the described outbound cross-tenant restriction case. The correct safeguard is: test both source outbound and resource inbound policy when diagnosing cross-tenant failures.

D:

This control manages future b2b guest invitation redemption drift, but it does not reduce the continuing exposure in the described outbound cross-tenant restriction case. The correct safeguard is: test both source outbound and resource inbound policy when diagnosing cross-tenant failures.
