Microsoft SC-300 Practice Test 35

Question 340

A scheduled overnight report daemon calls Microsoft Graph with client credentials and no signed-in employee session. The proposed change is: Request the supported application permissions needed for the daemon and obtain authorized administrator consent. After applying the intended configuration, which observation most directly proves that the required behavior works?

  1. Inspect the daemon's access token roles claim and run the intended Graph operation without a user sign-in.
  2. From a separate test tenant, complete an approved consent flow and verify creation of its local service principal.
  3. Acquire a token with the replacement before removing the original and confirm no consumer still relies on it.
  4. Decode a scoped access token and confirm the intended roles claim appears for the authorized API audience.

Explanation

Correct Answer

A:

Inspect the daemon's access token roles claim and run the intended Graph operation without a user sign-in. This directly tests the effective outcome, not merely that a configuration exists. It establishes whether the intended change works: request the supported application permissions needed for the daemon and obtain authorized administrator consent. Failure would be evident in this case: the daemon fails because its token lacks the Graph permission even though a developer consented to a delegated scope.

Incorrect Answers

B:

The proposed observation checks the different multitenant publisher app consent scenario. Even a successful test would not establish the requested outcome here: inspect the daemon's access token roles claim and run the intended Graph operation without a user sign-in.

C:

The proposed observation checks the different app secret expiration rollover scenario. Even a successful test would not establish the requested outcome here: inspect the daemon's access token roles claim and run the intended Graph operation without a user sign-in.

D:

The proposed observation checks the different app roles token claims scenario. Even a successful test would not establish the requested outcome here: inspect the daemon's access token roles claim and run the intended Graph operation without a user sign-in.

Question 341

The daemon fails because its token lacks the Graph permission even though a developer consented to a delegated scope. Which root cause best explains the described result rather than merely treating its symptoms?

  1. The application's supported account types do not allow use by the intended external organizational tenant.
  2. The application's actual redirect URI is not registered for the client.
  3. Delegated user scopes cannot substitute for application permission grants in client credential flow.
  4. No active credential remains that matches the daemon's configured client authentication.

Explanation

Correct Answer

C:

Delegated user scopes cannot substitute for application permission grants in client credential flow. This is the causal explanation of the observed behavior: the daemon fails because its token lacks the Graph permission even though a developer consented to a delegated scope. Address the underlying mechanism with: request the supported application permissions needed for the daemon and obtain authorized administrator consent. Then confirm: inspect the daemon's access token roles claim and run the intended Graph operation without a user sign-in.

Incorrect Answers

A:

This diagnosis fits a separate multitenant publisher app consent incident: A test customer tenant cannot consent because the app registration is restricted to accounts in the vendor's directory only. It does not explain this case's observed failure; delegated user scopes cannot substitute for application permission grants in client credential flow.

B:

This diagnosis fits a separate redirect uri security incident: The token endpoint rejects the request due to a redirect URI mismatch after the callback domain changes. It does not explain this case's observed failure; delegated user scopes cannot substitute for application permission grants in client credential flow.

D:

This diagnosis fits a separate app secret expiration rollover incident: The daemon begins receiving invalid_client immediately after the only existing secret expires. It does not explain this case's observed failure; delegated user scopes cannot substitute for application permission grants in client credential flow.

Question 342

A scheduled overnight report daemon calls Microsoft Graph with client credentials and no signed-in employee session. The initial implementation works. Which continuing control most directly prevents the same failure or drift from recurring?

  1. Plan overlapping certificate rollover and protect private keys from repository exposure.
  2. Require reviewed redirect URIs and avoid wildcard-like overly broad callbacks.
  3. Keep daemon application permissions narrower than interactive user permission bundles.
  4. Version app role values carefully and verify token claims after assignment or consent changes.

Explanation

Correct Answer

C:

Keep daemon application permissions narrower than interactive user permission bundles. This reduces future drift after the initial control is deployed: request the supported application permissions needed for the daemon and obtain authorized administrator consent. Recheck the actual behavior with: inspect the daemon's access token roles claim and run the intended Graph operation without a user sign-in.

Incorrect Answers

A:

This control manages future certificate credential for unattended client drift, but it does not reduce the continuing exposure in the described delegated versus application permissions case. The correct safeguard is: keep daemon application permissions narrower than interactive user permission bundles.

B:

This control manages future redirect uri security drift, but it does not reduce the continuing exposure in the described delegated versus application permissions case. The correct safeguard is: keep daemon application permissions narrower than interactive user permission bundles.

D:

This control manages future app roles token claims drift, but it does not reduce the continuing exposure in the described delegated versus application permissions case. The correct safeguard is: keep daemon application permissions narrower than interactive user permission bundles.

Question 343

A backend integration uses an app registration for client credentials and must replace a hard-coded client secret with a controlled certificate. Which proposed configuration or implementation directly meets the stated requirement?

  1. Upload an approved application certificate credential and use the corresponding private key in the client assertion process.
  2. Request the supported application permissions needed for the daemon and obtain authorized administrator consent.
  3. Register the exact approved HTTPS redirect URI matching the application callback and remove obsolete addresses.
  4. Create an authorized replacement credential, update consumers safely, validate tokens, then retire the expiring secret.

Explanation

Correct Answer

A:

Upload an approved application certificate credential and use the corresponding private key in the client assertion process. The solution acts at the intended identity, policy or application scope. A successful result is testable: acquire a test app token using the certificate and confirm old secret removal does not break service. The competing configuration error is: the credential presented by the client no longer matches an active trusted certificate on the app registration.

Incorrect Answers

B:

That action implements the separate delegated versus application permissions decision. It is appropriate when a scheduled overnight report daemon calls Microsoft Graph with client credentials and no signed-in employee session. The present case instead requires the specific certificate credential for unattended client change: upload an approved application certificate credential and use the corresponding private key in the client assertion process.

C:

That action implements the separate redirect uri security decision. It is appropriate when a web app registration is configured for the OAuth authorization code flow, but its authentication redirects are failing after a hostname change. The present case instead requires the specific certificate credential for unattended client change: upload an approved application certificate credential and use the corresponding private key in the client assertion process.

D:

That action implements the separate app secret expiration rollover decision. It is appropriate when a client-credential integration uses an app registration secret that expires next month and must avoid a midnight outage. The present case instead requires the specific certificate credential for unattended client change: upload an approved application certificate credential and use the corresponding private key in the client assertion process.

Question 344

A backend integration uses an app registration for client credentials and must replace a hard-coded client secret with a controlled certificate. The proposed change is: Upload an approved application certificate credential and use the corresponding private key in the client assertion process. After applying the intended configuration, which observation most directly proves that the required behavior works?

  1. Inspect the daemon's access token roles claim and run the intended Graph operation without a user sign-in.
  2. From a separate test tenant, complete an approved consent flow and verify creation of its local service principal.
  3. Acquire a test app token using the certificate and confirm old secret removal does not break service.
  4. Acquire a token with the replacement before removing the original and confirm no consumer still relies on it.

Explanation

Correct Answer

C:

Acquire a test app token using the certificate and confirm old secret removal does not break service. This directly tests the effective outcome, not merely that a configuration exists. It establishes whether the intended change works: upload an approved application certificate credential and use the corresponding private key in the client assertion process. Failure would be evident in this case: the integration fails after certificate rollover because the public certificate is updated but the application still signs with the old key.

Incorrect Answers

A:

The proposed observation checks the different delegated versus application permissions scenario. Even a successful test would not establish the requested outcome here: acquire a test app token using the certificate and confirm old secret removal does not break service.

B:

The proposed observation checks the different multitenant publisher app consent scenario. Even a successful test would not establish the requested outcome here: acquire a test app token using the certificate and confirm old secret removal does not break service.

D:

The proposed observation checks the different app secret expiration rollover scenario. Even a successful test would not establish the requested outcome here: acquire a test app token using the certificate and confirm old secret removal does not break service.

Question 345

The integration fails after certificate rollover because the public certificate is updated but the application still signs with the old key. Which root cause best explains the described result rather than merely treating its symptoms?

  1. The credential presented by the client no longer matches an active trusted certificate on the app registration.
  2. The application's supported account types do not allow use by the intended external organizational tenant.
  3. No active credential remains that matches the daemon's configured client authentication.
  4. Delegated user scopes cannot substitute for application permission grants in client credential flow.

Explanation

Correct Answer

A:

This is the causal explanation of the observed behavior: the integration fails after certificate rollover because the public certificate is updated but the application still signs with the old key. Address the underlying mechanism with: upload an approved application certificate credential and use the corresponding private key in the client assertion process.

It does not explain this case's observed failure; the credential presented by the client no longer matches an active trusted certificate on the app registration.

C:

This diagnosis fits a separate app secret expiration rollover incident: The daemon begins receiving invalid_client immediately after the only existing secret expires. It does not explain this case's observed failure; the credential presented by the client no longer matches an active trusted certificate on the app registration.

D:

It does not explain this case's observed failure; the credential presented by the client no longer matches an active trusted certificate on the app registration.

Question 346

A backend integration uses an app registration for client credentials and must replace a hard-coded client secret with a controlled certificate. The initial implementation works. Which continuing control most directly prevents the same failure or drift from recurring?

  1. Plan overlapping certificate rollover and protect private keys from repository exposure.
  2. Maintain credential expiry alerts and phased rollover with verified consumer inventory.
  3. Keep daemon application permissions narrower than interactive user permission bundles.
  4. Require reviewed redirect URIs and avoid wildcard-like overly broad callbacks.

Explanation

Correct Answer

A:

Plan overlapping certificate rollover and protect private keys from repository exposure. This reduces future drift after the initial control is deployed: upload an approved application certificate credential and use the corresponding private key in the client assertion process. Recheck the actual behavior with: acquire a test app token using the certificate and confirm old secret removal does not break service.

Incorrect Answers

B:

This control manages future app secret expiration rollover drift, but it does not reduce the continuing exposure in the described certificate credential for unattended client case. The correct safeguard is: plan overlapping certificate rollover and protect private keys from repository exposure.

C:

This control manages future delegated versus application permissions drift, but it does not reduce the continuing exposure in the described certificate credential for unattended client case. The correct safeguard is: plan overlapping certificate rollover and protect private keys from repository exposure.

D:

This control manages future redirect uri security drift, but it does not reduce the continuing exposure in the described certificate credential for unattended client case. The correct safeguard is: plan overlapping certificate rollover and protect private keys from repository exposure.

Question 347

A third-party SaaS app wants organization customers to consent through their own Microsoft Entra tenants. Which proposed configuration or implementation directly meets the stated requirement?

  1. Create an authorized replacement credential, update consumers safely, validate tokens, then retire the expiring secret.
  2. Upload an approved application certificate credential and use the corresponding private key in the client assertion process.
  3. Define appropriate app roles in the API app registration and assign the right principals to those roles.
  4. Configure the intended multitenant app registration and publish verified ownership/consent information appropriate for customer review.

Explanation

Correct Answer

D:

Configure the intended multitenant app registration and publish verified ownership/consent information appropriate for customer review. The solution acts at the intended identity, policy or application scope. A successful result is testable: from a separate test tenant, complete an approved consent flow and verify creation of its local service principal. The competing configuration error is: the application's supported account types do not allow use by the intended external organizational tenant.

Incorrect Answers

A:

That action implements the separate app secret expiration rollover decision. It is appropriate when a client-credential integration uses an app registration secret that expires next month and must avoid a midnight outage. The present case instead requires the specific multitenant publisher app consent change: configure the intended multitenant app registration and publish verified ownership/consent information appropriate for customer review.

B:

That action implements the separate certificate credential for unattended client decision. It is appropriate when a backend integration uses an app registration for client credentials and must replace a hard-coded client secret with a controlled certificate. The present case instead requires the specific multitenant publisher app consent change: configure the intended multitenant app registration and publish verified ownership/consent information appropriate for customer review.

C:

That action implements the separate app roles token claims decision. It is appropriate when a custom API wants the caller's Reader or Approver application role represented in tokens, with no manual access list inside the app. The present case instead requires the specific multitenant publisher app consent change: configure the intended multitenant app registration and publish verified ownership/consent information appropriate for customer review.

Question 348

A third-party SaaS app wants organization customers to consent through their own Microsoft Entra tenants. The proposed change is: Configure the intended multitenant app registration and publish verified ownership/consent information appropriate for customer review. After applying the intended configuration, which observation most directly proves that the required behavior works?

  1. Perform an authorization code login and verify the redirect URI and issuer/audience align with the app registration.
  2. Decode a scoped access token and confirm the intended roles claim appears for the authorized API audience.
  3. From a separate test tenant, complete an approved consent flow and verify creation of its local service principal.
  4. Acquire a test app token using the certificate and confirm old secret removal does not break service.

Explanation

Correct Answer

C:

From a separate test tenant, complete an approved consent flow and verify creation of its local service principal. This directly tests the effective outcome, not merely that a configuration exists. It establishes whether the intended change works: configure the intended multitenant app registration and publish verified ownership/consent information appropriate for customer review. Failure would be evident in this case: a test customer tenant cannot consent because the app registration is restricted to accounts in the vendor's directory only.

Incorrect Answers

A:

The proposed observation checks the different redirect uri security scenario. Even a successful test would not establish the requested outcome here: from a separate test tenant, complete an approved consent flow and verify creation of its local service principal.

B:

The proposed observation checks the different app roles token claims scenario. Even a successful test would not establish the requested outcome here: from a separate test tenant, complete an approved consent flow and verify creation of its local service principal.

D:

The proposed observation checks the different certificate credential for unattended client scenario. Even a successful test would not establish the requested outcome here: from a separate test tenant, complete an approved consent flow and verify creation of its local service principal.

Question 349

A test customer tenant cannot consent because the app registration is restricted to accounts in the vendor's directory only. Which root cause best explains the described result rather than merely treating its symptoms?

  1. No active credential remains that matches the daemon's configured client authentication.
  2. The app role was defined but not assigned to that user/group/service principal, or the token targets a different audience.
  3. Delegated user scopes cannot substitute for application permission grants in client credential flow.
  4. The application's supported account types do not allow use by the intended external organizational tenant.

Explanation

Correct Answer

D:

The application's supported account types do not allow use by the intended external organizational tenant. This is the causal explanation of the observed behavior: a test customer tenant cannot consent because the app registration is restricted to accounts in the vendor's directory only. Address the underlying mechanism with: configure the intended multitenant app registration and publish verified ownership/consent information appropriate for customer review. Then confirm: from a separate test tenant, complete an approved consent flow and verify creation of its local service principal.

Incorrect Answers

A:

This diagnosis fits a separate app secret expiration rollover incident: The daemon begins receiving invalid_client immediately after the only existing secret expires. It does not explain this case's observed failure; the application's supported account types do not allow use by the intended external organizational tenant.

B:

This diagnosis fits a separate app roles token claims incident: An employee can authenticate but the API rejects Reader operations because no app role is present in the token. It does not explain this case's observed failure; the application's supported account types do not allow use by the intended external organizational tenant.

C:

This diagnosis fits a separate delegated versus application permissions incident: The daemon fails because its token lacks the Graph permission even though a developer consented to a delegated scope. It does not explain this case's observed failure; the application's supported account types do not allow use by the intended external organizational tenant.

Question 350

A third-party SaaS app wants organization customers to consent through their own Microsoft Entra tenants. 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. Define appropriate app roles in the API app registration and assign the right principals to those roles.
  2. Version app role values carefully and verify token claims after assignment or consent changes.
  3. Request the supported application permissions needed for the daemon and obtain authorized administrator consent.
  4. Configure the intended multitenant app registration and publish verified ownership/consent information appropriate for customer review.
  5. Review publisher identity and least-privilege scopes when submitting changes to multitenant apps.

Explanation

Correct Answers

D:

Configure the intended multitenant app registration and publish verified ownership/consent information appropriate for customer review. The solution acts at the intended identity, policy or application scope. A successful result is testable: from a separate test tenant, complete an approved consent flow and verify creation of its local service principal. The competing configuration error is: the application's supported account types do not allow use by the intended external organizational tenant.

E:

Review publisher identity and least-privilege scopes when submitting changes to multitenant apps. This reduces future drift after the initial control is deployed: configure the intended multitenant app registration and publish verified ownership/consent information appropriate for customer review. Recheck the actual behavior with: from a separate test tenant, complete an approved consent flow and verify creation of its local service principal.

Incorrect Answers

A:

That action implements the separate app roles token claims decision. It is appropriate when a custom API wants the caller's Reader or Approver application role represented in tokens, with no manual access list inside the app. The present case instead requires the specific multitenant publisher app consent change: configure the intended multitenant app registration and publish verified ownership/consent information appropriate for customer review.

B:

This control manages future app roles token claims drift, but it does not reduce the continuing exposure in the described multitenant publisher app consent case. The correct safeguard is: review publisher identity and least-privilege scopes when submitting changes to multitenant apps.

C:

That action implements the separate delegated versus application permissions decision. It is appropriate when a scheduled overnight report daemon calls Microsoft Graph with client credentials and no signed-in employee session. The present case instead requires the specific multitenant publisher app consent change: configure the intended multitenant app registration and publish verified ownership/consent information appropriate for customer review.
