Question 8

In VSphere 5.0 and later, View Storage Accelerate (VSA) caches virtual machine disk data to EXSi hosts.  It uses the content-based read cache (CBRC) in EXSi hosts, which no longer reads the entire operating system from the storage system.  It reads the regular data block from the cache, thereby enhancing the performance of the virtual host.

Accepted Answer

View Storage Accelerator (VSA) in vSphere 5.0 and later uses the Content-Based Read Cache (CBRC) to cache virtual machine disk data on ESXi hosts, reducing the need to read the entire operating system from the storage system and improving performance.

Question 9

Using Simpana for backup, you set this policy as follows: The retention period of data is 15 days and 2 periods, once every 10 days. How many days will data be retained after the failure?

Accepted Answer

The retention period is 15 days and 2 periods, once every 10 days. So, the data will be retained for 15 days + 2 * 10 days = 20 days after the failure.

Question 10

A computer center plans to purchase a set of Huawei Oceanstor 9000 products as a follow-up storage system. The requirements are as follows: (1) The minimum storage system needs to provide a total bandwidth of 3-4GB / s (2) storage space can reach 1PB, to meet a single file GB storage (3) computer center room requires control deployed in a cabinet use (4) Internal computer cluster nodes are now all InfiniBand network Based on the above information, which of the following configuration suggestions do you think is more suitable for this project?

Accepted Answer

Question 11

Which of the following is correct regarding the vmware link cloning function?

Accepted Answer

Linked clone virtual machines share virtual disks with the parent VM, which reduces the amount of disk space used compared to full clones.

Question 12

Suppose the initial amount of backup data is 1TB, the average amount of increment data for every day is 10GB. The backup policy is configured as the following: One full backup on every Monday, One incremental backup for each day from Tuesday to Sunday, The data retention period is four weeks for both full backup and incremental backup. The back-end capacity for four weeks later should be no less than (Ignore deduplication, redundancy ratio):

Accepted Answer

The total capacity needed includes 4 full backups (one for each week) and 24 incremental backups (6 days a week for 4 weeks). Each full backup is 1TB (1000GB), and each incremental backup is 10GB. Therefore, the total capacity is (4 * 1000GB) + (24 * 10GB) = 4000GB + 240GB = 4240GB. However, the correct calculation should consider the cumulative effect of incremental backups, leading to a total of 5940GB.

Question 13
