Options
Q: 2
In a synchronous replication scenario, an application's peak write throughput is 16 MB/s, average write throughput is 500 KB/s, average write 1/0 size is 8 KB, private information overhead is about 11%, and the FC network bandwidth utilization rate is 70%. The throughput of the disaster recovery network must be at least ( ).

Q: 7
There are many services in the 8500 clustered NAS system that support system functions, such as NFS and CIFS basic service groups. Each service group is a collection of resources, each resource has an agent responsible for managing these resources, the availability of these resources directly or indirectly affect the status of the service. Which of the following is not an NFS service group resource agent?
Options
Q: 8
Info Replication supports copying the data at the same time using the home directory, extended attributes, ACL (access control list), WORM, and CIFS. NFS configuration information is also copied to the slave. When a disaster occurs, the master and slave stations can quickly take over after the switchover.
