Question 520

At Technology Center, central logs appear incomplete after a firewall change to the syslog collector. Which postchange observation is the strongest evidence of correct operation?

  1. Generate a test event and match timestamps and device identity at the collector.
  2. Show controlled service degradation is detected and accurately localized by UXI.
  3. Capture identifiable test traffic without dropping ordinary production forwarding.
  4. Trigger a safe lab threshold and verify historical record and alert generation.

Explanation

Correct Answer

A:

For Technology Center, the decisive mechanism is Syslog timestamps and forwarding. System logging accuracy needs both transport and synchronized timestamps. Generate a test event and match timestamps and device identity at the collector supplies measurable, case-relevant evidence that the intended behavior actually occurs.

The specific mechanism is system logging accuracy needs both transport and synchronized timestamps

Question 521

At Medical Annex, a tablet sees the SSID beacon but never completes association despite strong signal. What recurring protection should accompany this configuration?

  1. Change WLAN capability requirements in a tested pilot rather than disabling security campus-wide.
  2. Restrict sensitive management details on ports where topology advertisement is inappropriate.
  3. Maintain reserve PoE capacity and recheck the budget during AP model changes.
  4. Preserve approved transceiver and link-setting baselines for any future port migration.

Explanation

Correct Answer

A:

For Medical Annex, the decisive mechanism is 802.11 association sequence. 802.11 discovery and association occur before user traffic can be successfully forwarded. Change WLAN capability requirements in a tested pilot rather than disabling security campus-wide is an enduring limitation on the operational risk, not simply a one-time passing test.

Incorrect Answers

B:

This is relevant to LLDP topology and discovery, where lLDP supplies adjacent-device identity without proving end-to-end routing or authentication In the Medical Annex case, A precaution for another failure mode is not the enduring boundary needed here.

Restore a test tunnel and prove client traffic appears on intended gateway counters supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

This is relevant to Physical-link errors, where layer 1/2 corruption can degrade packets even though link status remains up In the Central Hall case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is cloud management connectivity does not imply a healthy user tunnel

B:

This is relevant to Routed blackhole, where route presence alone does not prove usable bidirectional forwarding In the Central Hall case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is cloud management connectivity does not imply a healthy user tunnel

C:

This is relevant to Wrong VLAN mapping, where wLAN-to-wired mapping errors can appear as a DHCP or authorization defect In the Central Hall case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is cloud management connectivity does not imply a healthy user tunnel

  3. Record VLAN allowlists and avoid a global all-VLAN trunk as a shortcut.
  4. Retain RADIUS failover and a defined restricted fallback for the expected device class.

Explanation

Correct Answer

B:

For Garden Hall, the decisive mechanism is LLDP topology and discovery. LLDP supplies adjacent-device identity without proving end-to-end routing or authentication. Restrict sensitive management details on ports where topology advertisement is inappropriate is an enduring limitation on the operational risk, not simply a one-time passing test.

Incorrect Answers

A:

This is relevant to 802.11 association sequence, where 802.11 discovery and association occur before user traffic can be successfully forwarded In the Garden Hall case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is lLDP supplies adjacent-device identity without proving end-to-end routing or authentication
