What does the customer need to understand about the upgrade?

A customer has a two-frame IBM TS4500 Tape Library with 24 IBM TS1150 drives. The L frame is the left-most frame and the customer wants to add slots for 1100 cartridges. The available physical space in the data center is limited, so high density (HD) frames are needed. The customer has some existing IBM TS3500 storage frames that could be repurposed.

What does the customer need to understand about the upgrade?
A . An IBM TS3500 storage frame must be upgraded to HD2 before it can be redeployed.
B . The IBM TS3500 storage frames must be installed to the right of the L frame.
C . One IBM TS3500 storage frame may be installed and must be frame position one
D . A redeployed IBM TS3500 storage frame must be the last (right-most) frame.

Answer: B

Explanation:

Leverage flexibility that enables the library to grow from both the right and the left side of the first L frame since models can be placed in any active position.
