A pointer-based virtual replica is created from a full volume mirror. What is the impact of restoring
from the mirror on the pointer-based virtual replica?

Which parameters determine the size of a bit map in full volume mirroring?

If a file system is unmounted prior to the creation of the replica, what is the possible result?

A company is planning to deploy synchronous array-based remote replication between two sites
over 13 MB/s ESCON links. The two sites are 50 miles apart. The workload profile of the
application is as follows:
Peak work load = 3,000 I/Os per second
Read/Write Ratio = 70:30
Write I/O block size = 8 KB
1 ms latency is added for every 125 miles
If the delay per channel extender is 0.5 milliseconds (ms) and one round trip (ESCON) equals four
passes, what is the link service time of this solution?

follows:
Peak work load = 3,000 I/Os per second
Read/Write Ratio = 70:30
Write I/O block size = 8 KB
Current average response time = 5 milliseconds (ms)
1 ms latency is added for every 125 miles
If the delay per channel extender is 0.5 ms and one round trip (ESCON) equals four passes, what
is the average response time of this solution?

An organization is using asynchronous remote replication between two sites. Based on business
requirements, they want to reduce their RPO without making a significant investment. They have
additional network bandwidth available to accommodate any change.
What is your recommendation to the organization?

Asynchronous remote replication over a 10 Gb/s Fibre Channel link is planned between sites. If
the upper limit of buffer-to-buffer credits is 180 and link utilization is 60%, what is the maximum
distance over which data can be replicated?

Asynchronous remote replication over a 2 Gb/s Fibre Channel link is planned between sites that
are 50 kilometers apart. How many buffer-to-buffer credits need to be configured to ensure that
utilization of the link is 70%?

Two sites are connected through an IP network that uses an MTU size of 9,000 bytes for remote
replication. However, an intermediate network does not support this packet size.

Which event(s) is likely to occur with the intermediate network?

In a synchronous replication design, what is the key consideration regarding the volume write
limits (VWL)?
