A. The ISL between switches is not configured.

B. SNMP is not configured properly.

C. br0 and br1 are not defined.

D. The cluster is using RDMA-enabled NICs.

An administrator has a custom backup application that requires a 2TB disk and runs in Windows. Throughput is considerably lower than expected. The application was installed on a VM with the following configuration:

1.

Four vCPUs with one core/vCPU

2.
