QUESTION 71
A company has several remote offices, and each office has its own backup infrastructure. Each remote office has a backup server, a storage node, and a physical tape library to back up data. The company is facing challenges in managing the backup environment.
Which recommendation would you make to reduce the company’s backup management challenges?
A. Replace all backup servers with one backup server
B. Replace all storage nodes with one storage node
C. Replace all physical tape libraries with one VTL
D. Replace all storage nodes with one backup server
Answer: A
QUESTION 72
A company uses NDMP to back up a NAS device to a dedicated tape library. The backup administrator is experiencing poor performance while restoring a small set of files.
What would you recommend to improve the recovery time?
A. Implement direct access restore
B. Configure NDMP three-way
C. Install a second NAS device
D. Perform restores using a separate storage node
Answer: A
QUESTION 73
What accurately represents a consolidated backup on a virtual machine?
A. Eliminates the need for a backup window
B. Increases the size of the backup window
C. Increases the load on the physical server
D. Eliminates the need for a storage node
Answer: A

QUESTION 76
What is an important consideration for replicating a database using asynchronous remote replication?
A. Maintaining write consistency
B. Distance between the two sites
C. Number of source devices
D. Number of buffer devices
Answer: A
QUESTION 77
How many round trips are required to complete a write operation when a Fibre Channel protocol is used for array-based synchronous remote replication?
A. 1
B. 2
C. 3
D. 4
Answer: B
QUESTION 78
A company plans to locate its disaster recovery site 1,000 kilometers away from its production site. You are recommending a solution that includes the use of high-end storage arrays running asynchronous replication. During the planning phase, you have estimated that:
– The asynchronous replication minimum cycle time is set to 30 seconds.
– It will take three hours to fail over to the secondary site’s hardware after declaring a disaster.
– After the failover to the secondary site, it will take another two hours to bring up the applications.
Based on the information provided, what is the minimum supported recovery time objective?
A. 30 seconds
B. 3 hours
C. 5 hours
D. 5 hours, 30 seconds
Answer: C
QUESTION 79
When designing an asynchronous array-based remote replication solution, which factors should be considered?
A. Buffer size, bandwidth, number of replication channels, and write workload
B. Locality of reference, number of replication channels, RPO, and read block size
C. Read response time, RPO, write block size, and write IO/s
D. Response time elongation, bandwidth, buffer size, and locality of reference
Answer: A
QUESTION 80
A company is planning to deploy synchronous array-based remote replication over Gigabit Ethernet links. The workload profile of the application to be replicated is as follows:
– 3,000 IO/s
– Read/Write Ratio = 70:30
– Write block size = 4 KB
– Distance between sites = 40 kilometers
– Write-acceleration devices will not be used
What is the approximate propagation delay for one write?
A. 0.02 ms
B. 0.2 ms
C. 0.4 ms
D. 20 ms
