Actual exam question for HP's HPE7-A01 exam

Question #: 42
Topic #: 10

You are troubleshooting an issue with a pair of Aruba CX 8360 switches configured with VSX Each switch has multiple VRFs. You need to find the IP address of a particular client device with a known MAC address You run the "show arp" command on the primary switch in the pair but do not find a matching entry for the client MAC address.

The client device is connected to an Aruba CX 6100 switch by VSX LAG.

Which action can be used to find the IP address successfully?

AOption A

BOption B

COption C

DOption D

Show Suggested Answer

Suggested Answer: B

The show arp command displays the ARP table for a specific VRF or all VRFs on the switch. The ARP table contains the IP address to MAC address mappings for hosts that are directly connected to the switch or reachable through a gateway. If the client device is connected to another switch by VSX LAG, the ARP entry for the client device will not be present on the primary switch unless it has communicated with it recently. Therefore, to find the IP address of the client device, the administrator should run the show arp command on the secondary switch in the VSX pair, specifying the VRF name that contains the client device's subnet.

Hold up, where's the 'Call the Aruba support hotline and beg for help' option? That's the only way I'm getting through this one.

Hmm, this is a tricky one. I'm torn between options B and C. Gotta love those Aruba switches and their little quirks, am I right?

I don't know, option D looks pretty interesting. Who knows, maybe there's some hidden magic in those Aruba commands that could solve this mystery.

Option C seems the most straightforward way to find the IP address. Why waste time with other methods when you can just check the MAC table on the CX 6100 switch?

I agree, checking the MAC table on the CX 6100 switch is the quickest way to find the IP address.
