Microsoft AB-900 Practice Test 40

Question 390

Leadership asks whether risky employee file transfers are rising across Insider Risk cases. Which Microsoft 365 capability is MOST appropriate?

  1. Enforce SharePoint restricted access control where eligible.
  2. Configure supported Purview lifecycle retention for AI interactions.
  3. Review Insider Risk Management trends and reports.
  4. Review SharePoint data access governance activity reports.

Explanation

Correct Answer

C:

Aggregated risk reporting describes activity patterns without changing access. This directly addresses trend monitoring of insider-risk alerts.

Incorrect Answers

A:

RAC adds a site-level group boundary above ordinary link permissions. That addresses hard restriction of a high-risk site, whereas the current case requires trend monitoring of insider-risk alerts.

B:

Retention policies are controls rather than just reports. It is used for mandatory preservation of AI interaction data; this scenario calls for trend monitoring of insider-risk alerts.

D:

Sharing reports reveal potentially overshared sites and trends. It is used for broad link-exposure risk identification; this scenario calls for trend monitoring of insider-risk alerts.

Question 391

The attorney requests all responsive documents and messages for formal discovery. Which approach solves the stated need?

  1. Use Communication Compliance review and escalation.
  2. Use Purview DLP alert investigation.
  3. Investigate an Insider Risk Management case.
  4. Use Purview eDiscovery case search and legal preservation tools.

Explanation

Correct Answer

D:

eDiscovery organizes litigation-related content finding and holding. This directly addresses formal legal evidence collection.

Incorrect Answers

A:

Communication Compliance handles supported workplace conduct messages. Its purpose is review of harmful employee messages; the specified need is formal legal evidence collection.

B:

DLP incidents show sensitive data matches and policy enforcement. It would support investigation of sensitive document transfer, not the stated formal legal evidence collection.

C:

Insider-risk evidence combines configured user-activity risk signals. Its purpose is insider-driven exfiltration case; the specified need is formal legal evidence collection.

Question 392

A risk reviewer must evaluate reports of policy violations in AI-generated collaboration messages. Which Microsoft 365 capability is MOST appropriate?

  1. Investigate a relevant Communication Compliance or DLP alert as appropriate.
  2. Use a suitable Purview Compliance Manager assessment.
  3. Review DSPM for AI classification and interaction insights.
  4. Search supported Copilot interaction items in Purview eDiscovery.

Explanation

Correct Answer

A:

Content policy and data-loss alerts address different violation classes. This directly addresses AI-related communication policy triage.

Incorrect Answers

B:

Compliance Manager supports framework-mapped control review and improvements. The action is relevant to assessment of AI-relevant compliance duties rather than AI-related communication policy triage.

C:

AI-specific signals can surface use of protected data categories. This helps with classified information used during AI interactions instead of the required AI-related communication policy triage.

D:

eDiscovery can retrieve supported recorded AI interactions for cases. The action is relevant to legally responsive Copilot conversations rather than AI-related communication policy triage.

Question 393

Administrators want to find sites where staff recently created many Anyone sharing links. Which action should the team take?

  1. Run a SharePoint data access governance sharing links activity report.
  2. Run the data access governance broad-internal-sharing report.
  3. Generate the data access governance site permissions snapshot report where eligible.
  4. Review applicable data access governance file sensitivity label reporting.

Explanation

Correct Answer

A:

Link activity reports flag sites with frequent broad sharing link creation. This directly addresses recent anonymous sharing link exposure.

Incorrect Answers

B:

Broad internal access can expose files beyond a business need. That addresses widespread internal file visibility, whereas the current case requires recent anonymous sharing link exposure.

C:

Permission snapshots describe a site's current effective permission footprint. It is used for point-in-time site permission breadth; this scenario calls for recent anonymous sharing link exposure.

D:

Classification snapshot reporting relates protected content to site-level exposure. That addresses classification-aware site exposure, whereas the current case requires recent anonymous sharing link exposure.

Question 394

A sensitive finance site must permit only members of an approved group even if old sharing links still exist. What is the most appropriate implementation?

  1. Inspect sharing link activity and applicable SharePoint audit or change history.
  2. Configure SharePoint restricted access control for the finance site.
  3. Start with a SharePoint data access governance report.
  4. Remove excessive file and site permissions after business-owner review.

Explanation

Correct Answer

B:

RAC imposes an additional group boundary on access to a site. This directly addresses explicit group-only site access despite old links.

Incorrect Answers

A:

Events and permission changes show how unintended sharing arose. It would support forensic link-creation attribution, not the stated explicit group-only site access despite old links.

C:

Reports detect access risk before a remediation decision is made. It would support assessment before disruptive restriction, not the stated explicit group-only site access despite old links.

D:

Direct permission cleanup addresses who can actually read content. Its purpose is removal of unneeded site and item readers; the specified need is explicit group-only site access despite old links.

Question 395

Central IT lacks the business context to decide which readers of a project site remain legitimate. Which action should the team take?

  1. Use the data access governance result to initiate an eligible site access review.
  2. Use a supported OneDrive-specific access governance route instead of unsupported site access review.
  3. Initiate a SharePoint site access review for the responsible site owner.
  4. Remove the contractor's unnecessary access and complete the site access review.

Explanation

Correct Answer

C:

Site access review delegates permission assessment to the data owner. This directly addresses owner-led permission recertification.

Incorrect Answers

A:

Governance reports can identify candidate sites for delegated review. The action is relevant to targeted review of a high-exposure site rather than owner-led permission recertification.

B:

SharePoint site access review has product scope limitations and is not interchangeable with OneDrive. This helps with respecting site-access-review scope instead of the required owner-led permission recertification.

D:

Review completion should include remediation and an accountable disposition. This helps with removal of abandoned project membership instead of the required owner-led permission recertification.

Question 396

Security wants to stop creation of anonymous Anyone links across the tenant where business policy prohibits them. What is the most appropriate implementation?

  1. Permit approved Anyone sharing only within the scoped authorized site policy.
  2. Remove or revoke the specific anonymous link and correct its source permissions.
  3. Review SharePoint sharing links activity reporting.
  4. Restrict external sharing link types in the SharePoint organization policy.

Explanation

Correct Answer

D:

Tenant sharing policies determine which link scopes may be created. This directly addresses prevention of future anonymous links.

Incorrect Answers

A:

Site-specific sharing design can allow intended public resources while controlling risk. That addresses bounded anonymous public publication, whereas the current case requires prevention of future anonymous links.

B:

Removing the link closes the existing possession-based access path. It is used for remediation of an exposed file link; this scenario calls for prevention of future anonymous links.

C:

Sharing link reports summarize past link creation for risk analysis. That addresses counting anonymous sharing exposure, whereas the current case requires prevention of future anonymous links.

Question 397

A finance site grants all employees access through Everyone except external users without an approved business need. Which action should the team take?

  1. Remove broad tenant-wide grants and replace them with named business groups.
  2. Keep an approved organization-wide internal sharing policy on the handbook.
  3. Use a SharePoint data access governance broad-internal-sharing report.
  4. Inspect effective SharePoint site permissions and group membership.

Explanation

Correct Answer

A:

Narrow membership stops internal oversharing that Copilot could surface. This directly addresses limiting companywide finance access.

Incorrect Answers

B:

Broad internal access can be appropriate for deliberately shared public-to-staff content. It would support deliberate all-employee document availability, not the stated limiting companywide finance access.

C:

Governance reports identify tenant-wide exposure patterns. Its purpose is discovery of Everyone-except-external-users sharing; the specified need is limiting companywide finance access.

D:

Permission review validates actual access after group changes. It would support current site reader inventory, not the stated limiting companywide finance access.

Question 398

A SharePoint site has not been used for a year and has no responsive business owner. What is the most appropriate implementation?

  1. Configure appropriate SharePoint Advanced Management site lifecycle policies.
  2. Apply supported SharePoint site lifecycle and ownership review.
  3. Assign and maintain accountable SharePoint site owners.
  4. Review SharePoint administrative change history and audit data.

Explanation

Correct Answer

B:

Lifecycle governance identifies abandoned sites for remediation. This directly addresses orphaned inactive site disposition.

Incorrect Answers

A:

Lifecycle policies govern recurring site ownership and inactivity risk. This helps with standardized site sprawl governance instead of the required orphaned inactive site disposition.

C:

Owners are responsible for reviewing and approving site-level access. This helps with defined data ownership for site access instead of the required orphaned inactive site disposition.

D:

Change records identify modifications that may increase exposure. The action is relevant to timing of site security changes rather than orphaned inactive site disposition.

Question 399

An internal confidential file is available to many employees despite being correctly labeled Confidential. Which action should the team take?

  1. Apply an eligible Purview sensitivity label with rights protection.
  2. Fix source permissions rather than trying to hide information using prompt instructions.
  3. Review and reduce effective SharePoint access permissions.
  4. Correlate file sensitivity label reporting with site access governance.

Explanation

Correct Answer

C:

A classification label alone does not guarantee the intended audience is narrow. This directly addresses confidentiality label with overly broad source access.

Incorrect Answers

A:

File-level encryption protects permitted use after download. It is used for persistent content protection beyond site access; this scenario calls for confidentiality label with overly broad source access.

B:

Copilot follows effective access; source governance determines visibility. That addresses underlying permissions correction for AI retrieval, whereas the current case requires confidentiality label with overly broad source access.

D:

Combined sensitivity and permissions evidence prioritizes oversharing risk. That addresses high-impact oversharing prioritization, whereas the current case requires confidentiality label with overly broad source access.

Question 400

The organization needs a group-only site boundary stronger than existing file share links. What is the most appropriate implementation?

  1. Use native SharePoint site permissions management.
  2. Use SharePoint data access governance reporting.
  3. Send a supported SharePoint site access review request.
  4. Enable eligible SharePoint Advanced Management restricted access control.

Explanation

Correct Answer

D:

Restricted access control limits site entry beyond ordinary sharing links. This directly addresses hard site access boundary.

Incorrect Answers

A:

Standard site permissions cover everyday membership and access decisions. It would support ordinary site membership changes, not the stated hard site access boundary.

B:

Governance reports consolidate access patterns at organizational scale. Its purpose is tenant-wide oversharing assessment; the specified need is hard site access boundary.

C:

Delegated reviews use owners' business knowledge to validate readers. It would support distributed site permission remediation, not the stated hard site access boundary.
