HPE0-V14 Exam - Question 25

A customer has requested that you provide them with an architecture and bill-of-materials for a stack of top-of-rack switches. The customer has 34 HPE DL360 servers in the rack, each with four 1GBASE-T Ethernet ports which need to be connected to the network.

The customer is upgrading 50% of the 1GBASE-T Ethernet ports on the servers to 10GBASE-T Ethernet ports and needs the switching to support the upgraded servers. They are opposed to a chassis switch, and want to keep the number of managed devices on the network to a minimum.

Which architecture meets the customer requirements?

Show Answer
Correct Answer: C

The customer requires a minimal number of managed devices and does not want a chassis switch. Each of their 34 servers has four Ethernet ports, totaling 136 ports, with 50% upgraded to 10GBASE-T. The architecture must support both 1GBASE-T and 10GBASE-T connections. Using one IRF stack of four HPE 5710 48-port 1/10GBASE-T switches meets these requirements by providing sufficient ports and allowing for a single manageable stack, thus minimizing the number of managed devices in the network.

Definitely C: Needs 4 switches for port count, customer wants minimum of managed devices so one stack, VSX only supports two switches so must be an IRF based stack. As to ShaunSong's comment, 10GBaseT ports also negotiate 1000BaseT so are inherently 1/10Gb capable.

Should be C, since Aruba VSX only supports two switches in a stack, and not four.

Agree with you. "Aruba VSX enables a distributed and redundant architecture that is highly available during upgrades inherently by architecture design. High availability is delivered through redundancy gained by deploying two chassis in the core with each chassis maintaining its independent control."

I guess it should be D? VSX only supports 2 switches in a stack for sure, however it doesnt have 1/10 switch models? https://buy.hpe.com/au/en/networking/networking-switches/hpe-flexfabric-5710-switch-series/p/1010868971

Because if it is the correct one, it is C. Do they change it?

It should be B. Here are the features of the 5710 High-performance, low-latency data center top-of-rack (ToR) switch aimed at expanding port connectivity while adding local switching capacity • HPE Intelligent Resilient Fabric (IRF) for virtualization and two-tier networks • High 1/10GbE wirespeed ports with 40GbE and 100GbE uplinks

Making correction it should be C. It is still the FlexFabric 5710.
