Dell EMC Specialist – Systems Administrator, PowerProtect DD — Question 26

Backup administrators have noticed slow backups on the AIX environment.
To fix the issue, what should the set large_send be for each NIC, and what should the NFS option be set to?

Answer options

• A. no and nfs_rfc1323=0
• B. yes and nfs_rfc1323=0
• C. no and nfs_rfc1323=1
• D. yes and nfs_rfc1323=1

Correct answer: D

Explanation

The correct setting of 'yes' for large_send and 'nfs_rfc1323=1' enables TCP window scaling, which improves performance in high latency environments like AIX. The other options either disable large_send or set NFS to a non-scalable configuration, hindering backup speeds.
