Question 4

You have configured BFD for OSPF on a CX switch and have noticed the BFD session stays down but the OSPF neighbor state is up. What could explain this behavior?

A. BFD has not been enabled at the global configuration level. B. The local switch uses OSPFv3, but the remote switch uses OSPFv2. C. BFD is not supported on OSPF broadcast links, so OSPF ignores the config. D. The remote switch does not support BFD.

Question 6

Which statement is valid when enabling ARP protection features on HPE Aruba Networking CX switches?

A. Client lease time on the DHCP server should be at least 3600s before enabling ARP protection. B. In an active network, you should generally wait at least a week after enabling DHCP snooping to enable ARP protection. C. Once you enable DHCP snooping, you can enable ARP protection, and you will have full information to mitigate security risks. D. DHCP server utilization is required for IP to MAC binding to enable ARP protection.

Question 7

Match where the configuration for loop-protection is defined on an AOS-CX switch. Options may be used more than once.

Discussion 0

Correct Answer:

Explanation:
Interface configuration: loop-protect
Global configuration: loop-protect action tx-rx-disable
Global configuration: loop-protect re-enable-timer 30
Global configuration: loop-protect transmit-interval 10
In the AOS-CX operating system, configuration for Loop Protection follows a " Global Parameter, Local Execution " model. This distinguishes it from STP, which often has more per-interface tunable parameters.
* Enabling the Feature (Interface configuration): The command loop-protect is entered within the interface context (e.g., interface 1/1/1). This command acts as a " trigger " or toggle that tells the switch to start sending and listening for loop-protection probe packets on that specific physical port or LAG.
* Defining the Behavior (Global configuration): The specific way the loop protection " engine " behaves is defined once for the entire switch in the global configuration context .
* loop-protect action tx-rx-disable: This sets the universal response if a loop is detected. The switch can be told to simply log the event, or physically disable the port (either just the transmitter, or both transmitter and receiver).
* loop-protect re-enable-timer 30: If a port is disabled due to a loop, this global timer defines how many seconds the switch waits before automatically attempting to bring the port back online to see if the loop has been physically removed.
* loop-protect transmit-interval 10: This defines how frequently the switch generates the proprietary loop protection packets.
* Why this structure exists: This model simplifies administration. You can change the sensitivity (interval) or the severity (action) for the entire switch in one place, while still having the granular control to only enable the feature on " risky " ports where unmanaged switches or hubs might be connected.

Question 8

A. Switch A show BFD sessions using 500ms B. Switch A show BFD sessions using 6000ms C. Switch A show BFD sessions using 2000ms D. Switch A show BFD sessions using 300ms
