HP Exam HPE6-A85 Topic 9 Question 27 Discussion

Actual exam question for HP's HPE6-A85 exam

Question #: 27
Topic #: 9

When using the OSPF dynamic routing protocol on an Aruba CX switch, what must match on the neighboring devices to exchange routes?

AHello timers

BDR configuration

CECMP method

DBDR configuration

Show Suggested Answer

Suggested Answer: A

To provide an LACP connection with the maximum available bandwidth, one should configure a link aggregation group (LAG) using all available ports that can be used for data transfer. Since the SFP56 ports are used for stacking, the next best option is to use the 2 SFP28 ports and as many SmartRate 5G (SR5) ports as possible on each switch, which would allow for a 16-member LAG, with 2 SFP28 and 6 SR5 ports on each switch contributing to the LAG.

Lucina, you must be the class clown. ECMP method? Really? I think you need to review your OSPF fundamentals, my friend.

You guys are overthinking this. The answer is clearly C) ECMP method. OSPF uses Equal-Cost Multi-Path (ECMP) to load-balance traffic, so the ECMP configuration must match on the neighboring devices. Easy peasy!

Hmm, I don't think it's either of those. I'm going to go with B) DR configuration. The Designated Router (DR) election process is crucial for OSPF to function, so the DR settings must be consistent.

I'm not sure, but I think it's either A) Hello timers or D) BDR configuration.

I'm not sure about that. Isn't it D) BDR configuration? I've heard that the Backup Designated Router (BDR) settings need to be the same for OSPF to work properly on Aruba CX switches.

I agree with Hubert, because Hello timers need to match for OSPF to work properly.

I think the answer is A) Hello timers. The OSPF hello timers need to match on neighboring devices for them to establish an adjacency and exchange routes.
