Question 250

A network security analyst needs exactly TWO case-specific control steps. A rural WAN circuit has occasional high packet loss and the operator wants forward error handling for important transactions. Which TWO actions directly belong to the safe diagnostic and remediation workflow? Select TWO answers.

  1. Collect evidence: Review packet-loss history, supported link-management profiles and the SD-WAN policy attachment.
  2. Alternative verification: Video sessions fail over when an applicable threshold is exceeded while the bulk-transfer policy remains distinct.
  3. Apply correction: Configure a supported SD-WAN Error Correction profile for the affected traffic and link it via policy after assessing tradeoffs.
  4. Competing correction: Configure a Traffic Distribution profile expressing permitted path preferences and bind it to the appropriate application SD-WAN rules.
  5. Alternative diagnostic: Check the branch folder membership, snippet/template scope, SD-WAN profile references and push status.

Explanation

Correct Answer

A:

Error correction can improve reliability under certain loss conditions but introduces bandwidth or processing costs. Success is demonstrated when: Controlled loss tests improve successful delivery without unacceptable bandwidth overhead.

C:

Error correction can improve reliability under certain loss conditions but introduces bandwidth or processing costs. The expected outcome is: Controlled loss tests improve successful delivery without unacceptable bandwidth overhead.

Incorrect Answers

B:

This corresponds to a different condition: A branch video-conferencing policy uses generic quality limits, failing to distinguish interactive sessions from large overnight transfers. Alternative verification: Video sessions fail over when an applicable threshold is exceeded while the bulk-transfer policy remains distinct.

D:

This corresponds to a different condition: A franchise has a backup MPLS circuit and a metered broadband link, but its SD-WAN policies distribute traffic equally despite cost constraints. Competing correction: Configure a Traffic Distribution profile expressing permitted path preferences and bind it to the appropriate application SD-WAN rules.

E:

This corresponds to a different condition: An enterprise deploys SD-WAN profiles to a branch folder but a new firewall outside that folder does not inherit the templates. The discriminating evidence is: Review packet-loss history, supported link-management profiles and the SD-WAN policy attachment.

Question 251

A supervisor is assessing the risks of a rushed remediation. A rural WAN circuit has occasional high packet loss and the operator wants forward error handling for important transactions. Which proposed shortcut should the analyst REJECT as unsafe or ineffective? Select ONE best answer.

  1. Enable packet duplication for all bulk backups without considering link capacity.
  2. Configure a supported SD-WAN Error Correction profile for the affected traffic and link it via policy after assessing tradeoffs.
  3. Controlled loss tests improve successful delivery without unacceptable bandwidth overhead.
  4. Review packet-loss history, supported link-management profiles and the SD-WAN policy attachment.

Explanation

Correct Answer

A:

This is the unsafe proposal in the stated scenario because it bypasses the control boundary. The required principle is: Error correction can improve reliability under certain loss conditions but introduces bandwidth or processing costs.

Incorrect Answers

B:

This is a controlled and useful step for the described condition, not the unsafe shortcut. The shortcut to reject is: Enable packet duplication for all bulk backups without considering link capacity.

C:

D:

This is a controlled and useful step for the described condition, not the unsafe shortcut. Review packet-loss history, supported link-management profiles and the SD-WAN policy attachment.

Question 252

A branch operations team must document a cause-based remediation with a measurable outcome. A rural WAN circuit has occasional high packet loss and the operator wants forward error handling for important transactions. What is the BEST complete investigation–change–verification plan? Select ONE best answer.

  1. Investigate: Inspect profile member priorities, link eligibility and matched application sessions during healthy and failed-link trials. Correct: Configure a Traffic Distribution profile expressing permitted path preferences and bind it to the appropriate application SD-WAN rules. Verify: Normal traffic follows the intended cost-aware preference while failover still works for approved applications.
  2. Investigate: Compare measured latency, jitter and loss against the configured thresholds and SD-WAN rule matches. Correct: Create a suitable Path Quality profile with latency, jitter and packet-loss thresholds for video and associate it with the matching SD-WAN rule. Verify: Video sessions fail over when an applicable threshold is exceeded while the bulk-transfer policy remains distinct.
  3. Investigate: Review packet-loss history, supported link-management profiles and the SD-WAN policy attachment. Correct: Configure a supported SD-WAN Error Correction profile for the affected traffic and link it via policy after assessing tradeoffs. Verify: Controlled loss tests improve successful delivery without unacceptable bandwidth overhead.
  4. Investigate: Check the branch folder membership, snippet/template scope, SD-WAN profile references and push status. Correct: Place the approved SD-WAN link-management and policy templates in the correct target scope, verify device association and push. Verify: The intended device receives the correct profile configuration without leaking branch policy to unrelated firewalls.
