What is a characteristic of FAST VP?
- A. Fast VP optimizes data replacement by moving 1 GB slices between disk tiers.
- B. Users can set the Fast VP data relocation rate.
- C. Users can enable or disable FAST VP at the LUN level.
- D. Fast VP data relocation runs in the background at all times once it is enabled.
Answer: B
Explanation:
Explanation
FAST VP (Fully Automated Storage Tiering for Virtual Pools) is a feature that automatically moves data within a storage pool based on the performance requirements and access patterns of the data. FAST VP data relocation runs in the background according to a user-defined schedule and rate. The schedule determines when the data relocation starts and ends, and the rate determines how much system resources are used for the data relocation. Users can set the Fast VP data relocation rate to High, Medium, Low, or None. High means that the data relocation has the highest priority and uses the most system resources, while None means that the data relocation is disabled. Fast VP data relocation does not run at all times, but only during the scheduled window. Fast VP optimizes data placement by moving 256 MB slices between disk tiers, not 1 GB slices.
Users cannot enable or disable FAST VP at the LUN level, but only at the storage pool level.

What are two prerequisites when creating host configuration for NFS client? (Choose two.)
- A. Tenant information
- B. Subnet access
- C. Hostname
- D. Network Address
Answer: C,D
Explanation:
Explanation
Host configuration is the process of defining the host properties and access permissions for a host that connects to the Dell Unity XT system. For NFS clients, the host configuration requires two prerequisites:
Network Address: The network address is the IP address or the subnet mask of the NFS client that identifies the host on the network. The network address is used to register the host on the Dell Unity XT system and to grant access to the NFS filesystems.
Hostname: The hostname is the name of the NFS client that is resolved by the DNS server or the local hosts file. The hostname is used to display the host information on the Unisphere UI and to enable host monitoring and alerting.
