HPE7-A03 Exam - Topic 1 Question 9 Discussion

Actual exam question for HP's HPE7-A03 exam
Question #: 9
Topic #: 1
[All HPE7-A03 Questions]

A global cruise line company needs to refresh its current fleet. They win refresh the insides' of the ship to be cost-effective and increase their sustain ability. They Mill replace the complete WLAN/LAN hardware of the ship. In this refresh, the company will not refresh Us current security requirements. The CIO also wants to limit the number of unused ports in the switches. Future expansion will always mean a refresh of hardware. They start with the smallest ship with a maximum of 800 guests

Each ship has a LAN infrastructure consisting of two core switches, up to 10 redundant distribution switches, and up to 500 access switches (400 cabins. 100 technical rooms). The Core switches are located in the MDF of the ship and the distribution switches are located in the IDFs of the ship. Each cabin and technical room gets one single access switch.

The cabling structure of the ship will not be refreshed. Each IDF is connected to the MDF by SMF. of which two pairs are available for the interconnect between the core and distribution. The length of SM fiber between MDF and IDF is less than 300 meters (930 ft) and the type used is 0S1. Each cabin is connected by a single 0M2 pair to the IDF. the maximum length is 60 meters (200 ft). Each technical room is connected by a single 0M2 pail to the IDF. with lengths between 100 and 150 meters (320 and 500 ft).

For each cabin/technical room the customer is looking to replace their current fan-less 2530/2540 without changing the requirements, except they need to upgrade the uplink to distribution switch to 10GbEto handle the increased network traffic, and the technical rooms need redundant power.

The WLAN infrastructure will be 1:1 refreshed without new cabling or new AP locations. Their WLAN Infrastructure is based on the 200/300 series Indoor and outdoor APs running instantOS (less than 300 APs). the customer has no change in WLAN requirements.

The cruise line company will replace its current Internet connection before the LAN/WLAN refresh. The new Internet connection will provide a 99.8% uptime, which is needed to ensure the paid guest Wi-Fi is always operational. With this new internet connection, the CIO of the cruise line wants to base the design on the ESP architecture from Aruba because Internet connection is guaranteed.

Based on best practices, what should you recommend as the correct optic type for the connection between the IDF and the technical rooms?

Show Suggested Answer Hide 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.

Option A could work too, but not sure it’s enough for future needs.

I feel like the SR transceiver is the safest bet here. It aligns with the 300 meters limit, but I need to double-check if the technical rooms' lengths would affect that choice.

I practiced a similar question where we had to consider the cabling and distances. I think the 10GBASE-T option might not be suitable since the distances are longer than 30 meters.

I'm a bit unsure about the LRM option. It seems like it could work, but I recall that the SR is generally preferred for shorter distances.

I remember we discussed the importance of choosing the right optic type based on distance and fiber type. I think the SR transceiver might be the best fit since the lengths are under 300 meters.

The question mentions the fiber type used is OS1, which is single-mode fiber. So I don't think the multimode options A and B are correct. I'm leaning towards C or D.

Okay, I think I've got it. The technical rooms are connected by OM2 fiber, and the max length is 150m, so option B looks like the right choice here.

Hmm, I think the key here is maintaining PSTN calling while evaluating Teams. Based on that, I'm leaning towards the "Skype for Business with Teams collaboration" option.

Okay, let me think this through step-by-step. The Exception Shielding pattern is supposed to prevent the service from sending back any message at all in case of an error, to avoid exposing vulnerabilities. So if that's not happening, then there must be something else going on. I'll need to carefully review the options and see if I can identify the root cause.

Ah, the age-old dilemma of choosing the right optic type. I bet the cruise line's engineers are having a swell time with this one, probably sipping piña coladas while we scratch our heads.

I'm going to have to go with option C, the Aruba 100 LC BID! 40 km-0 1330/1270 XCVR. It's the only one with the word 'XCVR' in it, so it must be the most advanced choice, right?

Really? You're all overthinking this. Just get the Aruba 10GBASE-T SFP+ RJ-45 30 m Cat6A Transceiver and call it a day. Who needs fiber when you can just use good old Cat6A?
