1. A customer reports performance problems on an XIV Gen3 system. After further analysis of performance statistics, it appears that latency is high for reads but writes are acceptable. I/O size is generally small, with more writes than reads. Which option is likely to help the situation?

A) install ECoE adapters in the host
B) implementvolume striping on the host
C) installSSDsintheXIVsystem
D) enable IBM Easy Tier on the volumes

2. For optimum redundancy, how many paths between the host and a 15 module XIV should be configured for each LUN?

A) 4 paths
B) 12 paths
C) 6 paths
D) 2 paths

3. A customer has purchased a six module XIV Gen3 for a new project, which is located in a new data center. A new requirement states that a portion of the project data must be replicated to an existing six module XIV (Gen2) at the customer's primary data center, 500 km away. The target XIV has sufficient capacity but no Fibre Channel connectivity exists between sites. The customer therefore decides to use iSCSI replication.
Which upgrade is required to meet the requirements?

A) add modules to the new (primary) XIV Gen3
B) add modules to the existing (secondary) XIV
C) add modules to both XIV systems
D) replace the new (primary) XIV Gen3 InfiniBand switches with Ethernet switches
