3.An asynchronous replication on an XIV system has been running for some time with no
issues. A synch job is scheduled for 4:00 AM, at which point all updated volumes will be
replicated to the DR site. By what method are the updates calculated?

8.A worldwide financial company is interested in XIV replication. Their requirement is to
replicate data between Chicago to Tokyo on an hourly basis. The data change rate ranges
from 50 MB/s to 100 MB/s. Assuming sufficient bandwidth, can the XIV system meet
these requirements?
A. No, XIV doesn’t have remote mirroring function.
B. Yes, XIV asynchronous mirroring can support it.
C. Yes, all XIV mirroring technologies can support it.
D. No, none of XIV mirroring technologies can support it.
Answer: B
9.A customer has two 10-module XIV systems, each located at a different site.
Synchronous replication is operating between the XIV systems in a bi-directional
configuration and using iSCSI as the transport. The sites are linked via Metropolitan Area
Network (MAN). A variety of business functions are sharing the site-to-site link with the
XIV replication including VoIP, remote desktop, email, and other business related
functions. There is currently no prioritization or quality of service being applied to the
site-to-site link. At random times during the month, a changing number of
business critical applications are experiencing severe performance degradation. At the
times when the performance degradation is occurring, VoIP users are reporting a large
number of dropped and lost calls. It has been noted, the performance degradation seems
to be worse during month-end processing but there are no measurements to support this
assertion. It has also been noted that the performance degradation does not seem to be
limited to servers hosted on the XIV systems. The customer has asked if adding additional
modules to the XIV systems would resolve the performance issue. Which of the
following items should be monitored to answer the customer’s question?
A. Site-to-site link latency.
B. CPU Utilization for each XIV system module.
C. CPU utilization on performance degraded servers.
D. Fibre Port bandwidth on non-XIV attached servers.
Answer: A
10.An asynchronous replication is created with a schedule of 20 seconds. Due to the
amount of data to replicate, an average synch job takes 30 seconds for this design. Which
of the following situations will apply?
A. Replication will not lag behind new data creation.
B. Replication will lag behind new data creation by an average of 40 seconds.
C. Replication will lag behind new data creation by an average of 20 seconds.
D. Replication will lag behind new data creation by an average of 30 seconds.
Answer: B
11.A governmental agency has purchased an XIV system to replace an IBM DS4300 that
is out of support.
The current host environment includes many AIX hosts with single HBAs. The manager of
information technology would like to better understand what options are available for data
migration. Which of the following statements describes the support level for migration in
this environment?
A. Single attached hosts are not supported with XIV.
B. Hosts cannot be migrated via host-based mirroring.
C. IBM DS4300 is not supported as an XIV data migration source.
D. Single attached hosts can be migrated with XIV data migration.
Answer: D

D. Native Host-Based Mirroring
Answer: B
13.In asynchronous replication, the “most_recent” snapshot represents:

at completion of replication.
D. the most recent snapshot taken of the master, existing on both the master and slave
XIV at completion of replication.
Answer: B

19.LUNs have been provisioned to a Red Hat Enterprise Linux server. However, the disks
