What is the impact of resynchronizing the copy on the pointer-based virtual replica?
A pointer-based virtual replica is created from a point-in-time (PIT) copy of a source LUN. What is
the impact of resynchronizing the copy on the pointer-based virtual replica?
What is the impact of restoring from the mirror on the pointer-based virtual replica?
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?

what is the link service time of this solution?
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?
what is the average response time of this solution?

What is your recommendation to the organization?
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.
