HP Exam HPE2-W09 Topic 1 Question 62 Discussion

Actual exam question for HP's HPE2-W09 exam
Question #: 62
Topic #: 1
[All HPE2-W09 Questions]

You are configuring Ethernet Ring Protection Switching (ERPS) on an ArubaOS-CX switch. Is this a guideline for configuring timers?

Solution: The hold off timer causes ERPS switches to delay unblocking a failed link after the link is restored. This can be useful to prevent frequent topology changes.

Show Suggested Answer Hide Answer
Suggested Answer: A

ERPS is a feature of ArubaOS-CX that prevents loops at layer 2 on ring networks1.ERPS uses a protocol called Ring Auto Protection Switching (RAPS) to detect link failures and perform fast traffic switchover1.ERPS has two timers that control the protection switching mechanism: guard timer and hold off timer1.The guard timer prevents false switching caused by delayed or lost RAPS PDUs1.The hold off timer causes ERPS switches to delay unblocking a failed link after the link is restored1.This can be useful to prevent frequent topology changes due to link flapping or network instability1. Therefore, this is a guideline for configuring timers for ERPS, and the correct answer is yes.For more information on ERPS and timers, refer to the Aruba Data Center Network Specialist (ADCNS) certification datasheet2and the ERPS Guide for your switch model1.

This question is a real piece of cake. The hold off timer is basically the network equivalent of letting your coffee cool down before you drink it. Gotta give those ERPS switches time to get their act together.

Duh, of course the hold off timer is a guideline. What kind of networking noob would say no to that? It's like having a car with no brakes - not a good idea.

I'm all for the hold off timer. Prevents those pesky topology changes from giving me a headache. Plus, it's just good networking hygiene, you know?

The hold off timer sounds like a great way to prevent ERPS switches from flipping out every time a link goes down and then back up. Gotta love a good delay to keep things stable.
