Question 220
A GitHub Release is published with a tag name already reused for another commit, undermining audit evidence. Choose TWO measures that implement and verify an effective Azure DevOps response to this specific situation. (Choose TWO.)
- Compare release tag history, signed commit identity, artifact provenance, and staging-to-production deployment references.
- Dismiss the known risk for protected release tags and verifiable version references and keep no evidence or accountable owner after deployment.
- Declare protected release tags and verifiable version references successful solely from a green pipeline status and skip checking its actual control outcome.
- Protect critical release tags and pin deployment records to immutable commit IDs and associated artifact digests.
- Bypass review and testing for protected release tags and verifiable version references whenever the release deadline is urgent, applying the change to production immediately.
Explanation
Correct Answers
A:Compare release tag history, signed commit identity, artifact provenance, and staging-to-production deployment references. A human-friendly release tag is not sufficient evidence when its target may be changed without control.
D:Protect critical release tags and pin deployment records to immutable commit IDs and associated artifact digests. A human-friendly release tag is not sufficient evidence when its target may be changed without control. Production can run different code than the reviewed release despite using the same version label.
Incorrect Answers
B:Dismiss the known risk for protected release tags and verifiable version references and keep no evidence or accountable owner after deployment. It conflicts with the stated operating condition: A human-friendly release tag is not sufficient evidence when its target may be changed without control.
C:Declare protected release tags and verifiable version references successful solely from a green pipeline status and skip checking its actual control outcome. It conflicts with the stated operating condition: A human-friendly release tag is not sufficient evidence when its target may be changed without control.
E:Bypass review and testing for protected release tags and verifiable version references whenever the release deadline is urgent, applying the change to production immediately. It conflicts with the stated operating condition: A human-friendly release tag is not sufficient evidence when its target may be changed without control.
Question 221
A developer resets a working branch and reports a critical test fix lost even though the commit may remain in local history. Which implementation BEST addresses the operational issue?
- Use reflog or known commit identifiers to recover the intended change, then reapply normal PR and validation rules.
- Apply supported partial-clone, sparse-checkout, or Scalar patterns tailored to service boundaries and CI workload needs.
- Use Git LFS or appropriate artifact storage for large binaries while retaining versioned pointer and permission management.
- Protect critical release tags and pin deployment records to immutable commit IDs and associated artifact digests.
Explanation
Correct Answer
A:Use reflog or known commit identifiers to recover the intended change, then reapply normal PR and validation rules. Git recovery can recover commit objects, but recovering content does not grant approval to deploy it. Recreating lost work manually can omit required changes or introduce an unreviewed release artifact.
Incorrect Answers
B:Apply supported partial-clone, sparse-checkout, or Scalar patterns tailored to service boundaries and CI workload needs.
C:Use Git LFS or appropriate artifact storage for large binaries while retaining versioned pointer and permission management. That applies to git lfs for oversized binary assets in version history, not recover deleted commits using git reflog safely.
D:Protect critical release tags and pin deployment records to immutable commit IDs and associated artifact digests. That applies to protected release tags and verifiable version references, not recover deleted commits using git reflog safely.
Question 222
A developer resets a working branch and reports a critical test fix lost even though the commit may remain in local history. How should the team validate the intended result?
- Compare release tag history, signed commit identity, artifact provenance, and staging-to-production deployment references.
- Locate the original commit hash, compare its diff with the issue, and rerun required tests after recovery.
- Measure checkout duration and verify a narrowed checkout still fetches all dependencies and required build scripts.
- Rebuild a prior release using package lock or submodule commit pins and compare retrieved component hashes.
Explanation
Correct Answer
B:Locate the original commit hash, compare its diff with the issue, and rerun required tests after recovery. Git recovery can recover commit objects, but recovering content does not grant approval to deploy it.
Incorrect Answers
A:Compare release tag history, signed commit identity, artifact provenance, and staging-to-production deployment references. That applies to protected release tags and verifiable version references, not recover deleted commits using git reflog safely.
C:Measure checkout duration and verify a narrowed checkout still fetches all dependencies and required build scripts. That applies to sparse checkout and scalar for very large monorepositories, not recover deleted commits using git reflog safely.
D:Rebuild a prior release using package lock or submodule commit pins and compare retrieved component hashes. That applies to cross-repository shared code via versioned packages, not recover deleted commits using git reflog safely.
Question 223
A developer resets a working branch and reports a critical test fix lost even though the commit may remain in local history. What is the underlying reason the existing approach fails?
- Cross-repository reuse needs stable dependency identities to prevent unreviewed cross-team changes.
- Removing a secret from current source does not invalidate leaked credentials or guarantee prior copies disappeared.
- Git recovery can recover commit objects, but recovering content does not grant approval to deploy it.
- Repository access is a sensitive software supply-chain boundary, not simply a convenience for team participation.
Explanation
Correct Answer
C:Git recovery can recover commit objects, but recovering content does not grant approval to deploy it. Recreating lost work manually can omit required changes or introduce an unreviewed release artifact.
Incorrect Answers
A:Cross-repository reuse needs stable dependency identities to prevent unreviewed cross-team changes. That applies to cross-repository shared code via versioned packages, not controlling principle for recover deleted commits using git reflog safely.
B:Removing a secret from current source does not invalidate leaked credentials or guarantee prior copies disappeared. That applies to removing committed secrets from git and rotating credentials, not controlling principle for recover deleted commits using git reflog safely.
D:Repository access is a sensitive software supply-chain boundary, not simply a convenience for team participation. That applies to least-privilege github organization collaborator permissions, not controlling principle for recover deleted commits using git reflog safely.
Question 224
A developer resets a working branch and reports a critical test fix lost even though the commit may remain in local history. Which recurring control most directly sustains the required behavior?
- Enforce file-size policies and maintain LFS availability and retention for required revisions.
- Enforce secret scanning, tight credential scopes, and training on safe Git history rewriting procedures.
- Document recovery actions and validate branch history and repository permissions before a restored commit is merged.
- Restrict tag deletion and modification and monitor unauthorized release reference changes.
Explanation
Correct Answer
C:Document recovery actions and validate branch history and repository permissions before a restored commit is merged. Recreating lost work manually can omit required changes or introduce an unreviewed release artifact.
Incorrect Answers
A:Enforce file-size policies and maintain LFS availability and retention for required revisions. This helps sustain a control for git lfs for oversized binary assets in version history; it does not directly stop recurrence of recover deleted commits using git reflog safely described in this case.
B:Enforce secret scanning, tight credential scopes, and training on safe Git history rewriting procedures. This helps sustain a control for removing committed secrets from git and rotating credentials; it does not directly stop recurrence of recover deleted commits using git reflog safely described in this case.
D:Restrict tag deletion and modification and monitor unauthorized release reference changes. This helps sustain a control for protected release tags and verifiable version references; it does not directly stop recurrence of recover deleted commits using git reflog safely described in this case.
Question 225
A developer resets a working branch and reports a critical test fix lost even though the commit may remain in local history. What is the MOST important consequence if this issue remains unresolved?
- Recreating lost work manually can omit required changes or introduce an unreviewed release artifact.
- Production can run different code than the reviewed release despite using the same version label.
- Repository growth can break build environments or make historical releases impossible to reconstruct.
- An unnecessary collaborator privilege can enable unauthorized source changes or exfiltrate proprietary code.
Explanation
Correct Answer
A:Recreating lost work manually can omit required changes or introduce an unreviewed release artifact. This is the directly relevant business or security consequence of recover deleted commits using git reflog safely. Root cause: Git recovery can recover commit objects, but recovering content does not grant approval to deploy it.
Incorrect Answers
B:Production can run different code than the reviewed release despite using the same version label. That risk is relevant to protected release tags and verifiable version references, but the specific unresolved condition here concerns recover deleted commits using git reflog safely and has a different direct consequence.
C:Repository growth can break build environments or make historical releases impossible to reconstruct. That risk is relevant to git lfs for oversized binary assets in version history, but the specific unresolved condition here concerns recover deleted commits using git reflog safely and has a different direct consequence.
D:An unnecessary collaborator privilege can enable unauthorized source changes or exfiltrate proprietary code. That risk is relevant to least-privilege github organization collaborator permissions, but the specific unresolved condition here concerns recover deleted commits using git reflog safely and has a different direct consequence.
Question 226
A release manager accidentally deletes an unmerged hotfix branch and attempts to reconstruct it from memory alone. Which solution should be prioritized to resolve the stated failure?
- Apply supported partial-clone, sparse-checkout, or Scalar patterns tailored to service boundaries and CI workload needs.
- Use Git LFS or appropriate artifact storage for large binaries while retaining versioned pointer and permission management.
- Protect critical release tags and pin deployment records to immutable commit IDs and associated artifact digests.
- Use reflog or known commit identifiers to recover the intended change, then reapply normal PR and validation rules.
