[All E20-585 Questions]

What is a recommended best practice when implementing the Dell EMC Data Domain VTL feature?

  • A. Do not use persistent binding
  • B. Three fabric hop limit
  • C. Enable Multiplexing/Parallelism
  • D. Switch encryption
Show Suggested Answer Hide Answer
Suggested Answer: A 🗳️
Configure VTL access group and bind the initiator and target.
Discover and configure VTL on the hosts
Configure the host operating system Fibre Channel driver for LUN-persistent binding or, preferably, use persistently-named operating system device special
files.
✑ Dedicate an HBA port on the backup host for use with the Data Domain VTL LUNs.
Etc.
Note: VTL - Virtual Tape Library.
Incorrect Answers:
C, D: Multiplexing, compression, and encryption of backup data were introduced to provide read parallelism as well as enhanced security and performance during backups. Backing up to a Data Domain system is inherently more secure than tape, and does not suffer performance degradation due to slow backup streams.
Thus the recommendation is to disable any of these features when using a Data Domain system as the target for RMAN.
