A) Encrypting data-in-flight
B) Encrypting data-at-rest
C) Password protect each file
D) Use file permissions

Accepted Answer

Encrypting data-at-rest ensures that data on the drives is not usable in case of a failed drive replacement.

Question 2

A company needs to replicate a database from its main office to a disaster recovery site 3,000 km away with a five minute recovery point objective. Which type of replication should the company use to replicate the data?
A) Synchronous
B) Asynchronous
C) Multi-synchronous
D) Local replication

Accepted Answer

Asynchronous replication is suitable for long distances like 3,000 km, as it allows data to be replicated without waiting for an acknowledgment from the disaster recovery site, thus meeting the five-minute recovery point objective.

Question 10

You are installing an OLTP application on a new server. The I/O profile of the application consists of 100% random read operations of 8 kilobyte transfers. You need to determine which HBA to use in your application to accommodate 50,000 IOPS. What is the minimum FC link speed that will satisfy the application's requirements?
A) 1 Gbps
B) 2 Gbps
C) 4 Gbps
D) 8 Gbps

Accepted Answer

To calculate the required FC link speed, multiply the IOPS by the transfer size and convert to Gbps: 50,000 IOPS * 8 KB = 400,000 KB/s = 400 MB/s. Converting to Gbps: 400 MB/s * 8 = 3.2 Gbps. Therefore, a 4 Gbps link is the minimum required.

Question 11

You have replaced an HBA and are trying to add it to an existing zone using the FC switch GUI interface. You are unable to do so. Why is this happening?
A) The OS login has not occurred.
B) The Web login has not occurred.
C) The fabric login has not occurred.
D) The port login has occurred.

Accepted Answer

The fabric login has not occurred, which is necessary for the HBA to be recognized and added to the zone in the FC switch GUI interface.

Question 12

After provisioning a new LUN to a host, new storage cannot be detected on the host. Which three actions should be performed to troubleshoot this problem? (Choose three.)
A) Scan memory on a host.
B) Scan for new storage on the host,
C) Verify that LUN mapping is correct.
D) Verify that zoning on the FC switch is correct.
E) Verify that the size of memory pages and block size is the same.

Accepted Answer

Scanning for new storage on the host ensures the host recognizes the new LUN. Verifying LUN mapping ensures the LUN is correctly assigned to the host. Checking zoning on the FC switch ensures proper connectivity between the host and storage.

Question 13

You determine that throughput between a server and an FC storage array is lower than expected. Your privileges only allow you to change the configuration of the HBA on the server. Which configuration setting can you change to increase throughput?
A) Queue length
B) Queue depth
C) Topology
D) Class 1 service

Accepted Answer

Queue depth refers to the number of I/O operations that can be queued at the HBA. Increasing the queue depth can allow more operations to be processed simultaneously, potentially increasing throughput.

Question 14

You need to implement a solution for a high transaction database which should have the lowest write latency as possible and still be able to sustain a failure of a single drive in a RAID group. Which type of RAID you would use?
A) RAID 0

Question 15

You have twelve 500 GB drives and you need to provide two LUNs using RAID 6 protection for a customer. What will be the size of each LUN?
A) 1.5 TB
B) 1.75 TB
C) 2 TB
D) 2.25 TB

Accepted Answer

RAID 6 requires at least four drives and uses two drives for parity. With twelve 500 GB drives, you have a total of 6 TB of usable space (12 drives x 500 GB = 6 TB). RAID 6 will use 2 drives for parity, leaving 10 drives for data. Therefore, each LUN can be 2 TB (5 drives x 500 GB = 2.5 TB per LUN, but since we need two LUNs, each will be 2 TB).

Question 17

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. Why does this happen?
A) Incorrect zoning
B) Incorrect multipathing policy
C) Incorrect LUN masking
D) Incorrect LUN size

Accepted Answer

Incorrect zoning can lead to fewer paths being available to the LUNs because zoning controls which devices can communicate with each other in a SAN environment. If zoning is not set up correctly, some paths may be blocked, resulting in fewer available paths.

Question 18

Your company does a full backup on Sunday night and incremental backups from Monday through Saturday at midnight. The full backup requires two tapes and each incremental backup requires one tape. There is a system failure Wednesday morning. How many tapes will be used to restore to the most current backup?
A) 1
B) 3
C) 4
D) 8

Accepted Answer

To restore to the most current backup, you need the full backup from Sunday (2 tapes) and the incremental backups from Monday and Tuesday (1 tape each), totaling 4 tapes.

Question 19

What are two concerns when trying to migrate from one cloud storage provider to another one? (Choose two.)
