Which of the following would increase availability from a virtualization host to a storage device?
A. Trunking
B. Multipathing
C. Link aggregation
D. VLANs
Answer: B
Multipathing is a technique that lets you use more than one physical path that transfers data between the host and an external storage device.
In case of a failure of any element in the SAN network, such as an adapter, switch, or cable, ESXi can switch to another physical path, which does not use the failed component. This process of path switching to avoid failed components is known as path failover.
