Which architecture meets the customer requirements?

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?
A . One VSX stack of four Aruba 8320 48-port 1/10GBASE-T switches
B. Two IRF stacks of two HPE 5710 48-port 1/10GBASE-T switches
C. One IRF stack of four HPE 5710 48-port 1/10GBASE-T switches
D. Two VSX stacks of two Aruba 8320 48-port 1/10GBASE-T switches

Answer: C

Explanation:

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.
