Question # 10

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.

Question # 11

A number of servers are experiencing slower than expected performance. Analyzing the server, switch, and storage logs do not indicate any issues. You have been asked by the customer to address this issue.

What will improve performance?

A.

Increase the current queue depth setting from 1.

B.

Change the frame size from 2148 bytes,

C.

Decrease the buffer-to-buffer credits setting.

D.

Enable write caching functionality for the device driver.

Question # 12

Your company uses a cryptographic key system to encrypt tapes. After several years of use and thousands of tapes shipped to off-site locations, an IT audit reveals that encryption keys have been inadvertently stored as ciphertext on file shares to which everyone in the company has read permissions.

Which response reflects industry best practice?

A.

All data encrypted with the keys exposed as ciphertext should be considered safe.

B.

All data encrypted with the keys exposed as ciphertext and not yet sent off-site as an encrypted tape should be re-keyed (decrypted and re-encrypted using a new key).

C.

All data encrypted with the keys exposed as ciphertext should be re-keyed (decrypted and re-encrypted using a new key).

D.

All data encrypted with the keys exposed as ciphertext should be considered safe as ciphertext is very difficult to use.

Question # 13

Your CTO is concerned over misuse of corporate storage assets because an employee was found to be hosting a music library on one of the SANs storage arrays. You have been instructed to provide some level of device security to the corporate FC SAN. FC has a number of cost-effective (free) industry standard protection mechanisms that provide or restrict user access to SAN resources.

Which two FC provided mechanisms would you implement first? (Choose two.)

A.

LUN masking

B.

Device authentication and authorization

C.

Zoning

D.

Key management system

Question # 14

Only one of many servers has poor performance within an enterprise SAN. The server administrator has found high disk timeout values without a decrease in throughput. The server has multiple paths to the storage system but only one path is active at this time.

What should the storage administrator monitor to assist with troubleshooting?

A.

Number of errors on the active storage port

B.

IOPS on the active storage port

C.

MBps on the active storage port

D.

Buffer-to-buffer utilization by the active storage port
