Question 7

A customer has purchased a 4-node N8500 clustered NAS storage system. The enterprise-edition
engine nodes have two CPUs, 10GE network ports, and 48 GB cache. The performance of an engine
node reaches 700 MB/s. The back-end storage uses the S5600T, which is configured with 80 SAS disks
divided into eight 9-disk RAID 5 groups. Each RAID group has one hot spare disk. The performance of
each SAS disk in the 9-disk RAID 5 groups is 30 MB/s. According to the preceding information, what is
the overall performance of the N8500 without considering other factors?

• A. 700 MB/s
• B. 2800 MB/s
• C. 1920 MB/s
• D. 2400 MB/s

Question 8

Which of the following are considered when planning the deployment of an N8000 clustered NAS
storage system? (Select three)

• A. Evenly distribute service loads among all cluster nodes. Employ port bonding to increase network bandwidths and enhance protection capability.
• B. Plan the types of file systems for the storage system based on the performance and data integrity requirements of customers' environments.
• C. Plan various RAID groups for the storage system to address the data integrity and read/write performancerequirements of different application scenarios.
• D. Select operating systems based on application requirements.

Question 9

If an OceanStor 9000 storage system consists of four M nodes and uses 10GE for the back-end
network, how many IP addresses must be planned for the back-end storage network segment?

recommended threshold is 3 GB, the soft threshold is 4 GB, the grace period is 10 days, and the hard
threshold is 6 GB. If user A has written 3.1 GB data in the /dir directory, which of the following
statements are correct? (Select two.)

• A. The system reports an alarm indicating thatthe threshold is exceeded.
• B. User A can continue to write data in the /dir directory.
• C. User A can continue to write data in the /dir directory for another 10 days.
• D. User A cannot continue to write data in the /dir directory.
