What is the purpose of a Proxy NAS server?
- A. Access snapshot replicas on the destination side of a replicated file resource.
- B. Access snapshots for testing production NAS servers.
- C. Increase performance for shared network connections that access NAS servers.
- D. Increase security of production NAS servers.
Answer: A
Explanation:
Explanation
The purpose of a Proxy NAS server is to access snapshot replicas on the destination side of a replicated file resource. A Proxy NAS server is a temporary NAS server that is created on the destination system to mount a snapshot replica of a replicated file system. This allows the user to access the data on the snapshot replica for testing, recovery, or other purposes. A Proxy NAS server does not increase performance or security of production NAS servers, nor does it access snapshots for testing production NAS servers.

NEW QUESTION # 199
A storage engineer must grant access of a Dell Unity XT provisioned NFS datastore to ESXi-1.dell.local. The NAS server used to create the datastore is configured for NFSv4 protocol with Kerberos NFS owner authentication.
Which permission level is required for the ESXi host?
- A. Read/write, enable Root
- B. Read-only
- C. Read/write
Answer: A
Explanation:
Explanation
To grant access of a Dell Unity XT provisioned NFS datastore to an ESXi host, the permission level required for the host depends on the NFS protocol and authentication method used by the NAS server. For NFSv4 with Kerberos NFS owner authentication, the ESXi host must have the Read/write, enable Root permission level.
This allows the ESXi host to read and write data to the datastore, as well as perform administrative tasks such as creating and deleting virtual machines. The Read/write permission level alone is not sufficient, as it does not allow the ESXihost to perform root-level operations on the datastore. The Read-only permission level only allows the ESXi host to read data from the datastore, but not write or modify it. References: Dell EMC Unity:
Configuring hosts to access NFS1, page 9.

NEW QUESTION # 207
Which two actions are recommended according to best practices when connecting iSCSI host to a Dell Unity XT system? (Choose two.)
- A. Interfaces should be on separate subnets.
- B. Use private network for iSCSI interfaces.
- C. Manually register host on storage array.
- D. Use standard NIC for iSCSI.
Answer: A,B
Explanation:
Explanation
Two actions that are recommended according to best practices when connecting iSCSI host to a Dell Unity XT system are to ensure that the interfaces are on separate subnets and to use a private network for iSCSI interfaces. These actions can improve the performance, security, and availability of the iSCSI network. Having interfaces on separate subnets can prevent broadcast storms, reduce network congestion, and enable multipathing. Using a private network for iSCSI interfaces can isolate the iSCSI traffic from other network traffic, reduce the risk of interference or attacks, and simplify the network configuration. Manually registering host on storage array and using standard NIC for iSCSI are not recommended actions, as they can introduce errors, inefficiencies, and limitations.
