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
A company has a storage subsystem that supports a variety of replication options. They have purchased an identical array and placed it at a secondary site 4,200 km away and want to keep the two arrays as closely synchronized as possible.
Which solution should be chosen?
A. Asynchronous replication is the only replication option for distances of this length.
B. Synchronous replication is the only replication option for distances over 4,000 km.
C. Snapshots allow for data to be quickly captured, copied, and mounted from one storage array to another and is the ideal solution for all distances.
D. Synchronous replication will keep the arrays in the closest sync and is ideal for short distances such as 4,200 km.
What should be considered when implementing remote replication of storage?
A. The IOPS requirements at the primary site
B. The geographical location of the primary site
C. The availability of communication links
D. The availability of server hardware at the secondary site
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 segmented.
Which statement is correct?
A. The port is isolated until a fabric rebuild occurs,
B. The port is isolated until a fabric re-configuration occurs.
C. The system administrator must manually correct the issue that caused segmentation (port isolation) and then start the Build Fabric (BF) process.
D. The system administrator must manually correct the issue that caused port isolation (segmentation) and then start the Reconfiguration Fabric (RCF) process.
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.
You are designing a security solution for a storage array which stores customer credit card information.
Data on the storage array must be encrypted and if necessary, you want to be able to revoke access to data on demand.
In addition to encryption, which solution would allow you to do this in a secure and automated fashion?
A. Use a manual record deletion solution.
B. Physically destroy hard drives holding the data
C. Store data indefinitely.
D. Use the key management solution.
You have a new storage array with the following drive types:
1.
SAS (6 Gbps)
2.
SSD
3.
SATA (6 Gbps)
4.
FC(4Gbps)
You need to decide which drive type to use based on speed, cost, and drive availability for your Tier 1
storage.
Which type of drive would you choose?
A. SSD
B. SAS
C. SATA
D. FC
You have a server which is booting from a SAN. After adding new SAN storage to a host, the host will not boot from the SAN.
What will resolve this problem?
A. LUN masking
B. Persistent binding
C. Trunking
D. Multiplex binding
The CIO would like to segregate management device IP network traffic from server IP network traffic within the data center to limit potential security threats.
What would be used to accomplish this?
A. IPsec
B. Firewall
C. VLANs
D. PKI
Which type of a backup changes the archive bit?
A. Full
B. Differential
C. Incremental
D. Block-level
