A customer has a virtualized data center. The virtual hosts use virtual distributed switches with
multiple redundant uplinks, and these uplinks use Link Aggregation Control Protocol (LACP).
Which technology, available in HP switches, enhances high availability in this environment?
A.
Virtual Ethernet Port Aggregator (VEPA) combines redundant server links into a single highbandwidth trunk
B.
NetStream and sFlow technologies provide the built-in capability to optimize bandwidth flows
dynamically
C.
Intelligent Resilient Framework (IRF) allows redundant server links to connect to different
physical switches
D.
Fibre Channel over Ethernet (FCoE) allows the virtual hosts to send storage traffic over the
server Ethernet uplinks if the FC connection fails
A – VEPA is for consolidating VM traffic
B – Netstream and sFlow is for analyzing traffic
C – This whole test, and whole study guide, is basically one big circlejerk for how awesome IRF is. and how it’s proprietary to HP switches. 99% sure this is the correct answer.
D – This is available on other switches too, not special to HP. Also, it deals with storage, and the question is talking about link aggregation and availability

C is correct. HA need 2 switches, server uses LACP, 2 switches must support stacking.

Same as #97. C is right.
