NEW QUESTION 64
Refer to the exhibits.
Exhibit 1
Exhibit 2
Switch-1 and Switch-2 are configured to provide VRRP in VLAN 2. The default gateway for VLAN 2 is set to the VRRP virtual IP. Client-1 in VLAN 2 cannot ping its default gateway.
Based on the exhibits, what can administrators determine?
- A. The VRRP preempt delay time has not yet expired, and administrators should try to ping the gateway again in several minutes.
- B. Preempt mode is enabled on both Switch-1 and Switch-2, so the Master role continues to alternate between them, and the pings go astray.
- C. Switch-1 and Switch-2 have the same virtual router ID. The conflict interferes with connectivity.
- D. This is the expected behavior, and Switch-1 should still be able to route traffic for Client-1.
Answer: D
NEW QUESTION 65
Refer to the exhibit.
Switch-1 and Switch-2 connect on interface A23. The switches experience a connectivity issue. The network administrator sees that both switches show this interface as up. The administrator sees the output shows in the exhibit on Switch-1.
What is a typical issue that could cause this output?
- A. mismatched IP addresses on the VLAN for the link
- B. a hardware issue, such as a broken cable
- C. asymmetric routing introduced by a routing configuration error

- D. the mismatch between the key-strings in the chains for VLAN 10 and VLAN 11 on Switch-1
Answer: A
NEW QUESTION 68
Refer to the exhibits.
Exhibit 1
Exhibit 2
In the exhibits, VLAN 20 under a device name indicates that the device is configured with that VLAN. The exhibits also indicate whether VLAN 20 is statically configured on each link, either as an untagged or a tagged VLAN. If the link has no label, VLAN 20 is not statically configured on that link.
A network administrator needs to deploy AOS-Switches at the access layer. They enforce 802.1X on edge ports. In the exhibits, Switch-1 represents the access layer switches. The plan calls for users to be dynamically assigned to VLAN 20 or VLAN 30, based on identity. If the RADIUS server authorizes the user but does not assign a VLAN, the user should be assigned to VLAN 30. Switch-2 is the default router for the user VLANs.
Which exhibit shows the correct plan for VLAN 20 in the wired infrastructure?
- A. B
- B. D
- C. A
- D. C
Answer: D
NEW QUESTION 69

- B. Use PAPI enhanced security.
- C. Configure extended IP ACLs on the AOS-Switches to filter the traffic.
- D. Use tunneled node to send traffic through an Aruba Mobility Controller.
Answer: D
NEW QUESTION 70
