primary data center. The company has built an out-of-region disaster recovery data center and intends to
implement a standby ERP system with an eight hour RTO and 30 minute RPO.
Which architectural approach to implement service continuity for the ERP database will meet the RTO and
RPO targets?

Question5: You want to visibly verify FC port initialization by reading an analyzer trace. Your objective is to find the
frames associated with the initialization protocol to ensure that the FC device is operating correctly during
the login process, to be recognized as part of the switched fabric, and appear in a directory of attached FC
devices.
What must all Fibre Channel devices do to accomplish this?

Question6: A storage subsystems Web browser management interface reports that the subsystem has become
degraded and remotely opens a service request with the vendor. Your vendors level three storage support
engineer wants to remotely access your storage subsystem for troubleshooting.
What is a SNIA Storage Security Best Current Practices solution?

Question7: Two different departments have funded the purchase of a new director-class switch. Each department
wants to have control of the fabric. Two logical switches will need to be created, each with its own set of
administrators.
Which feature must be enabled on the switch to do this?

Question8: You have been asked to secure your FC switches in the data center. Unsecure protocols have already
been disabled but you also need to restrict access to the switches only from specific IP addresses located
on the production network.

Question9: A small business with an IP SAN and NAS storage is experiencing slow response times on the servers
which have NAS storage resources.
Which two should the storage administrator monitor to determine the root cause? (Choose two.)

allocated. The storage administrator must specify the amount of additional storage needed for local copies
for approximately half of the active storage.
How much additional storage should the administrator request?

Question11: You have completed installing your FC SAN. When everything is powered on, numerous devices are not
available. You need to verify that the devices appear within the FC fabric by accessing the appropriate FC
service that provides a list of devices and their respective function.

and storage logs do not indicate any issues. You have been asked by the customer to address this issue.
What will improve performance?

Question14: You have been asked to implement a remote data replication scheme. The current data center is mostly
constructed of FC components and the corporation is highly invested in the technology. The remote data
center needs a synchronous replication solution.

Question15: You are provisioning storage to a host with multipathing software installed and correctly configured. You
discover that there are four paths to LUNs instead of the expected eight paths.

Question16: You need to merge two existing FC fabrics. After connecting the ISL to join the fabrics, numerous switches
segment.
What should be done to prevent the segmentation?

Question17: A solution architect needs to know how your switches enforce zoning. The enforcement method and
identification type being used in your current FC switches must provide the highest level of security.
Which zoning enforcement should you use?

replication agents installed on the database server. After a disaster, you are unable to bring up the
database at the DR site.
What is the cause?

Question28: You need to add an iSCSI host and storage array to your environment. Your manager wants at least two
options that allow all iSCSI initiators to query a central management server to locate the address of all
iSCSI resources (e.g., iSCSI initiators, targets, switches, and management stations).
Which two protocol methods would be used? (Choose two.)

Question29: Five out of 4S servers using one particular enterprise storage system are experiencing performance
degradation during normal working hours. All 48 servers have similar workload characteristics. There are
multiple disk groups that make up your enterprise storage.
What should be monitored to determine the root cause?

replacement HBA port, but the missing paths have still not recovered.
Which action would you perform next?

Question46: You have received an emergency call from the night shift after they attempted to merge three small SANs
in the engineering department. Once completed, all devices in SANs A and B communicate with one
another but SAN C could not communicate with either of the other SANs because the fabric has become
