Which of the following are functions of the ESCOM’s in-band appliance?

A.
It minimizes the drawback of routing tables.

B.
It permits the organization to retain its existing infrastructure.

C.
The in-band appliance is not permitted to configure and discover all storage.

D.
None of the above.

Explanation:
ESCOM’s in-band appliance creates a new interconnecting layer between the telecom and ESCON architectures, providing three important functions:
1. It minimizes the drawback of routing tables, because all storage traffic is routed to, and
all storage devices are controlled by, the appliance. This minimizes the complexity found in a large telecom model.
2. The in-band appliance is permitted to configure and discover all storage. SAN
administrators no longer face the current masking and zoning headaches presented by LUNs.
3. It permits the organization to retain its existing infrastructure and gradually grow into
the new environment.
