HPE7-A03 Exam - Topic 1 Question 14 Discussion

Actual exam question for HP's HPE7-A03 exam

Question #: 14
Topic #: 1

The clients existing network is experiencing trouble with voice occasionally dropping out on phone calls between office locations, it Is determined that no packet loss is occurring and QOS is likely the cause. With what phenomenon Is the client currently experiencing issues?

AOption A

BOption B

COption C

Show Suggested Answer

Suggested Answer: C

Based on the requirements provided by 'Don't Buy at Us,' the updated design needs to accommodate 25GbE uplinks and a minimum of 7 stacks of 48-port Aruba switches for the EMEA-DISTR. Option C is the most suitable based on best practices, as it proposes:

A core configuration consisting of two Aruba 8360-12C in VSX for the collapsed core with ISL of 2x100GbE DAC, which will provide robust core networking with high-speed interconnects, suitable for the demands of a regional distribution center and headquarters.

Aggregation with two stacks, each with 2 Aruba 8360-12C in VSX (ISL 2x100GbE DAC), accommodating the uplink capacity requirements.

Access stacks with a total of 17 stacks of Aruba 6300F 48-port 1GbE Class 4 PoE with 4-port SFP56 (each stack has 4 members, VSF with 50GbE VSF links, 2 x 25GbE uplinks per stack), which exceeds the minimum requirement of 7 stacks and provides the necessary uplink bandwidth.

This configuration supports the 25GbE uplink speeds, satisfies the required number of switch stacks for the EMEA distribution center, and is compatible with the existing 25GbE-certified fiber infrastructure at HQ2 and EMEA-DISTR.

Definitely QOS-related, but could be other factors too!

I think it's more about latency than jitter, though.

Wait, no packet loss? That's surprising!

Totally agree, QOS issues can really mess with voice quality.

Sounds like a classic case of jitter affecting the calls.

I think the answer might be related to latency since the calls are dropping out, but I'm not completely confident. I wish I had reviewed more on this topic!

I feel like I read that QoS can cause problems like this, but I can't recall the exact term. Is it something like packet delay variation?

This seems similar to a practice question I did about voice quality issues. I think it might be related to jitter, but I could be mixing it up with something else.

I remember studying about QoS issues, but I'm not entirely sure which phenomenon this relates to. Could it be jitter or latency?

This is a good one to think through. Since QoS is mentioned as the likely cause, I'm guessing the issue is related to how the network is prioritizing or handling the voice traffic. I'll carefully consider each option to see which one fits best.

I'm a little confused by this question. The options don't seem to directly match the problem description. I'll need to re-read it carefully and try to connect the dots between the sympHyman and the possible causes.

Okay, I think I've got this. Based on the info provided, the client is likely experiencing issues with jitter, which can cause voice quality problems even without packet loss. I'll go with Option B.

Hmm, I'm a bit unsure about this one. The question mentions no packet loss, so I'm not sure if it's a bandwidth issue. I'll need to think through the options and see which one best fits the problem description.

This looks like a tricky QoS question. I'll need to carefully review the information about the voice call issues and the options to determine the likely cause.

I'm a bit confused by all the EVPN terminology in this question. Maybe I should skip it for now and come back to it later if I have time. Don't want to waste too much time on something I'm unsure about.

Okay, I've got this. The key is to focus on how environmental factors like magnetism, radiation, and pollution can interfere with the electronic components running the software. That's the best explanation for why software failures can be caused by environmental conditions.

Wow, this is a tough one. I'm gonna have to go with Option A though. Packet loss is the only thing that really makes sense given the problem description.
