Question 283

On the command line of the N8500 (V200R001) clustered NAS system, you run the NFS> share add / vx / xs-cmfs 100.43.13.210 command.

One system that is used NFS sharing has IP address 100.43.13.11. If the client operating system is Suse Linux, which of the following access to the description of the file system is correct: (multiple choice)

Not just the host with IP 100.43.13.210 can access this NFS share

To query the client for all the NFS shares on the service IP, use the command: showmount -e 100.43.13.11

Mount the NFS shared file system locally and execute: mount -t nfs 100.43.13.11:xs-cmfs / mnt

Verify that NFS shared file system has been mounted locally, executable: mount

Question 288

Production time is Monday to Friday 8:00 to 18:00. There are three LUNs, respectively LUN1, LUN2, LUN3, LUN1 with a size of 500G, all IO.

The average response time needs to be within 5ms, the size of LUN2 is 4TB, the coexistence of hot and cold data (with 12.5% of the hot data), and the size of LUN3 is 10TB. If performance requirements are not high and the engineer plans to use SmartTier, which of the following description is correct? (Multiple choice)

Use 3-tier Tier, 1TB high performance layer, 4TB performance layer, 10TB capacity layer, and configure LUN1 to allocate high-performance layer capacity first, LUN2 preferentially allocates performance layer capacity and LUN3preferentially allocates capacity layer capacity

Use 3-tier Tier, 1TB high-performance layer, 4TB performance layer, 10TB capacity layer, configure LUN1 and LUN2 to migrate automatically, and LUN3 priority allocation of low-performance layer capacity

The use of 3-tier Tier, high-performance layer 1TB, performance layer is 4TB, capacity layer is 10TB, while configuring LUN1, LUN2, LUN automatic relocation. The LUN3 is migrated preferentially to the low-performance layer

Set the monitoring period of the Smart tier to 8:00 to 18:00 every day from Monday to Friday. The migration period is not overlapped with the monitoring period
