D. Fibre Channel

Which type of a backup changes the archive bit?

You want to prevent unauthorized switches from connecting to your company's fabrics. What should you do?

A. Configure ACLs.

B. Implement CHAP.

C. Deploy FC-SP policy.

D. Implement binding lists.

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?

A. IOPS per RAID array

B. Cache read hit ratio

C. Traffic levels on the SAN switches

D. Clone sessions

You receive a ticket from a database group which is complaining about slow access to storage on only one particular server, as compared to other servers in an active-active cluster. You verify zoning and LUN masking which are fine. On the FC switch, you verify link speed, errors, and throughput for the FC switch ports used by this server. There are no errors on the ports and the link speed is the same as on the switch ports used by other servers in the cluster. You notice that on one port on the FC switch used by this server, that there is no throughput at all. What is causing the problem?

A. The switch has obsolete firmware.

B. There are too many ports used on the FC switch.

C. Multipathing was not configured for load-balancing.

D. The switch is over-subscribed.

After the storage administrator merged two multi-vendor FC SANs, an error indicates that two ports have become isolated causing a segmentation to exist in the fabric.

Which two events would cause this? (Choose two.)

A. Overlapping zones

B. Different port names

C. Unsupported routing protocols

D. Different link speeds

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?

A. ACL

B. Virtual SAN

C. Virtual LAN

D. Virtual Fabrics

Which type of storage replication is required, at a minimum, for a non-critical application?

A. Synchronous

B. Asynchronous

C. Semi-synchronous

D. Multi-synchronous

Only one of many servers is suffering poor performance with a nearline (Tier 2) storage system. The server administrator has not discovered any obvious root cause. The server has multiple paths to the storage system but only one path is active. Routine monitoring by the storage administrator has determined that a single storage port has received a high number of bad frames.

What should the SAN administrator do?

A. Determine the source of duplicate frames.

B. Verify that the host ports are correctly zoned.

C. Find the source of frames with CRC errors.

D. Collect new performance data and compare to the baseline.

The system administrator has received complaints about the decreased performance of two LUNs. When you investigate the port being used to connect to the LUNs, you discover that the port has achieved its maximum throughput. You also discover that there are other ports available on the storage array that are not oversubscribed.

Which specific driver is needed to balance workloads between the host and storage?

A. SCSI driver

B. TCP/IP driver

C. Failover driver

D. Multi-path driver
