NEW QUESTION # 77
A systems administrator has deployed a Dell Unity XT 380F system with 15x 1 92 TB SSD drives, in a RAID
5 dynamic pool Shortly after deployment, the administrator wants to expand the capacity of the system and use larger drives to increase the density What will happen if the administrator adds 4x 3 84 TB SSD drives?
- A. The mixing of drive types is not supported and the operation will fail
- B. Three of the drives will be added with a fourth reserved as spare
- C. Only half of the capacity of the new drives will be available
- D. The full capacity of the drives will be available
Answer: B
Explanation:
Explanation
If the administrator adds 4x 3 84 TB SSD drives to a Dell Unity XT 380F system with 15x 1 92 TB SSD drives, in a RAID 5 dynamic pool, three of the drives will be added with a fourth reserved as a spare. This will increase the total capacity of the system, but the mixing of drive types is not supported, so the operation will not fail. The full capacity of the drives will be available and can be used to store data.

NEW QUESTION # 90
What is the minimum RPO that can be configured on a Dell Unity XT block-asynchronous replication session?
- A. 60 minutes
- B. 1 minute
- C. 5 minutes
- D. 20 minutes
Answer: C
Explanation:
Explanation
The minimum RPO (Recovery Point Objective) that can be configured on a Dell Unity XT block-asynchronous replication session is 5 minutes. RPO is a measure of how much data can be lost in the event of a disaster, and it's typically measured in minutes. The lower the RPO, the less data can be lost.
Block-asynchronous replication is a replication method that copies data blocks, rather than files, between the source and the target. The data is copied at regular intervals, and if a disaster occurs at any point in time, the data on the target will be no more than 5 minutes old. The shorter the RPO, the more frequently data is copied and the less data is at risk of being lost in case of a disaster. It's important to note that this is the minimum RPO for block-asynchronous replication, it can be set to a higher value if needed.
