Question 1100

At Lakeside Classroom, a topology change moves the root toward a low-bandwidth edge switch. What should the engineer implement first to correct the stated condition?

  1. Establish the appropriate spanning-tree priority to retain an intentional distribution root.
  2. Set up a separate reachable VSX keepalive path with valid source and peer addressing.
  3. Build a supported VSX ISL with enough capacity and verify peer state consistency.
  4. Set up matching active-gateway address and MAC settings on the applicable VSX SVIs.

Explanation

Correct Answer

A:

For Lakeside Classroom, the decisive mechanism is RSTP root placement. RSTP uses a root bridge and port roles to build a loop-free Layer 2 topology. Set the appropriate spanning-tree priority to retain an intentional distribution root establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

B:

This is relevant to VSX keepalive separation, where the VSX keepalive helps distinguish peer failure from ISL failure In the Lakeside Classroom case, Changing that neighboring feature does not implement the missing function. The specific mechanism is rSTP uses a root bridge and port roles to build a loop-free Layer 2 topology

C:

This is relevant to VSX inter-switch link, where vSX peers synchronize selected state over an ISL while retaining independent control planes In the Lakeside Classroom case, Changing that neighboring feature does not implement the missing function. The specific mechanism is rSTP uses a root bridge and port roles to build a loop-free Layer 2 topology

D:

This is relevant to VSX active gateway, where vSX active gateway allows distributed L3 gateway forwarding when configured consistently In the Lakeside Classroom case, Changing that neighboring feature does not implement the missing function. The specific mechanism is rSTP uses a root bridge and port roles to build a loop-free Layer 2 topology

Question 1101

At West Auditorium, a client on VLAN 145 cannot obtain a lease because the DHCP server is in a routed services VRF. How should the engineer validate success against the stated requirement?

  1. Capture a test client flow at its designated wired VLAN or gateway policy point.
  2. See the AP obtain correct management addressing and report online in Central.
  3. Confirm both intended members distribute traffic and single-member loss is tolerated.
  4. Obtain a correctly scoped lease with gateway and DNS while unauthorized servers are rejected.

Explanation

Correct Answer

D:

For West Auditorium, the decisive mechanism is Campus DHCP relay. DHCP relay forwards client requests across routed boundaries; switching alone does not. Obtain a correctly scoped lease with gateway and DNS while unauthorized servers are rejected supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

This is relevant to Bridge versus tunneled WLAN traffic, where bridge SSIDs forward locally; tunneled SSIDs use the gateway data path for policy In the West Auditorium case, That test could pass while the actual user-facing requirement still fails.

Verify rejected identities cannot reach internal resources while approved identities succeed supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

This is relevant to Wired 802.1X port access, where 802.1X authorizes port traffic through EAPOL and the authentication server decision In the South Science Wing case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is authentication rejection is not the same as RADIUS server unavailability

B:

This is relevant to RADIUS authorization timeout, where authentication server reachability and retry order influence network-admission decisions In the South Science Wing case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is authentication rejection is not the same as RADIUS server unavailability

C:

This is relevant to Supplicant reauthentication intervals, where wired reauthentication intervals can affect session continuity if handshake timing is inadequate In the South Science Wing case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is authentication rejection is not the same as RADIUS server unavailability

Question 1105

At Innovation Studio, a secure corporate SSID needs appropriate enterprise authentication and protected management frames. Which diagnostic comparison would distinguish this fault from nearby mechanisms?

  1. Examine association RSN capability and failed security negotiation status.
  2. Examine certificate chain expiry dates CRL/OCSP reachability and client errors.
  3. Examine effective roles group policy and same-VLAN as well as routed flows.
  4. Examine start interim and stop records mapped to the NAD and user.

Explanation

Correct Answer

A:

For Innovation Studio, the decisive mechanism is WPA3 Enterprise compatibility. WPA3-Enterprise builds on supported enterprise security capabilities with stronger protections. Inspect association RSN capability and failed security negotiation status is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

Question 1110

At Research Hub, a campus gateway never receives employee SSID packets because the WLAN is set to bridge locally. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Preserve management-plane isolation and avoid moving monitoring to an unrestricted production VRF.
  2. Choose approved bridge or tunneled forwarding mode and correctly map AP VLAN or gateway cluster.
  3. Demonstrate subscription device identity Central assignment and management reachability in the authorized tenant.
  4. Assess roaming and segmentation impacts before changing WLAN forwarding mode.

Explanation

Correct Answers

B:

This is the implementation element for the Research Hub case: Bridge SSIDs forward locally; tunneled SSIDs use the gateway data path for policy. The specific action Choose approved bridge or tunneled forwarding mode and correctly map AP VLAN or gateway cluster addresses the stated fault; the question also requires a persistent risk control.

D:

This is the continuing risk-control element for Research Hub. Assess roaming and segmentation impacts before changing WLAN forwarding mode prevents a future regression or unauthorized relaxation of the repair; it complements, rather than replaces, the implementation.

Incorrect Answers

A:

This may be an ongoing precaution for Management VRF reachability: AOS-CX management VRF and default forwarding VRF may have separate reachability. It does not resolve the Bridge versus tunneled WLAN traffic requirement in Research Hub and is not one of the two controls requested. The direct mechanism here is bridge SSIDs forward locally; tunneled SSIDs use the gateway data path for policy

C:

This may be a configuration step for Central device onboarding: Cloud inventory association and device management connectivity are separate onboarding requirements. It does not resolve the Bridge versus tunneled WLAN traffic requirement in Research Hub and is not one of the two controls requested. The direct mechanism here is bridge SSIDs forward locally; tunneled SSIDs use the gateway data path for policy
