Discuss HP HPE7-A01 Exam Topic 4 Question 12

When setting up an Aruba CX VSX pair, which information does the Inter-Switch Link Protocol configuration use in the configuration created?

Ahello interval is disabled by default

Bhello interval is based on the value set by dead interval

Chello interval 100ms by default

Dhello interval is 1s by default

Suggested Answer: C

Loop protection is a feature that detects and prevents loops in layer 2 networks. Loop protection can be enabled on ports, LAGs, or VLANs. When loop protection is enabled, the switch sends periodic loop protection messages on the interface and expects to receive them back.If a loop protection message is received back on the same interface, it indicates a loop and the switch takes an action to disable the interface or block traffic on it3. The loop-protect re-enable-timer command is used to configure the length of time the switch waits before re-enabling an interface that was disabled due to loop detection.The default value is 0, which means that the interface remains disabled until manually re-enabled3.To automate the process of resuming the port operational state once a loop on a client port is cleared, the loop-protect re-enable-timer command can be used with a non-zero value on the interface range that includes the client ports3. Therefore, answer C is correct.

Really? I thought it was based on the dead interval.

Sina 11 months ago

Nope, it's definitely disabled by default.

Amber 11 months ago

Wait, isn't it 100ms by default?

Charlene 12 months ago

Totally agree with that!

Nana 12 months ago

I think hello interval is 1s by default.

Ruthann 12 months ago

I’m confused about the default settings. I thought the hello interval was disabled by default, but that doesn’t sound right now.

Armanda 1 year ago

I’m pretty certain that the hello interval is 1s by default. It aligns with what I’ve seen in the configuration guides.

Wei 1 year ago

I remember practicing a question about hello intervals, and I think it mentioned something about 100ms, but that seems too fast for a default.

Ernie 1 year ago

I think the hello interval is set to 1 second by default, but I’m not entirely sure.

Roslyn 1 year ago

I'm not entirely sure about the default hello interval, but I think option D saying it's 1s sounds plausible. I'll go with that.

Rolland 1 year ago

I remember learning that the hello interval is disabled by default, so I'll select option A.

Marylyn 1 year ago

The hello interval being 100ms by default sounds right to me, so I'll choose option C.

Derick 1 year ago

Hmm, I'm a bit confused on the default settings for the hello interval. I'll have to think this through carefully.

Adelle 1 year ago

I'm pretty sure the hello interval is based on the dead interval, so I'll go with option B.

I'm not totally confident on this one. The wording of the question is a bit confusing to me. I'll need to re-read it a few times and think through the different answer choices before making a decision.

I think the key is to emphasize that a server is a central device that delivers the services and capabilities that users require, whether that's file storage, web hosting, email, or anything else. Gotta keep it straightforward and focused on the user's needs.

Wynell 1 year ago

Hmm, I'm a bit unsure about this one. Should the progress really be discussed weekly? That seems like a lot of meetings. I'll have to think through the pros and cons of the different options.

Devorah 1 year ago

This seems like a straightforward question. I'll focus on the relevance to my business sector and target audience.

I bet the guy who wrote this question is laughing maniacally somewhere, waiting to see how many people fall for the QSVI trap. MAC tables all the way, baby!

I always double check for MAC tables when setting up an Aruba CX VSX pair.

Yaeko 1 year ago

↳ replying to Adolph

Yeah, the QSVI option is a sneaky one, but MAC tables are the key here.

Definitely MAC tables, don't fall for the QSVI trap!

A) QSVI

Domonique 1 year ago

QSVI? Is that even a real thing? I'm just going to go with the obvious answer - B, MAC tables. Though I do wonder who comes up with these wacky options sometimes.

Denae 1 year ago

Hmm, RPVST+? That's for spanning tree, not VSX. I'm going with B - MAC tables. Gotta love these trick questions!

Delsie 1 year ago

I agree, it must be a trick question. MAC tables make more sense for VSX.

Katie 1 year ago

↳ replying to Denae

Yeah, RPVST+ is definitely for spanning tree, not VSX.

I think B - MAC tables is the correct answer.

Lou 2 years ago

UDLD? Really? That's for detecting one-way fiber links, not for VSX configuration. I think the answer is B - MAC tables.

Barney 1 year ago

↳ replying to Lou

Yes, the correct answer is B - MAC tables.

Evangelina 1 year ago

↳ replying to Lou

I agree, UDLD is not used for VSX configuration.

Sophia 2 years ago

The Inter-Switch Link Protocol configuration definitely uses the MAC tables. That's the core purpose of a VSX pair - to share MAC information between the switches.

Herminia 2 years ago

Hmm, I'm not sure. Maybe we should review the documentation to confirm.

Benedict 2 years ago

I believe it uses QSVI for the configuration.

Herminia 2 years ago

I think the Inter-Switch Link Protocol configuration uses UDLD.
