151. Which technology enhances the performance of the Huawei OceanStor 9000 application? (Multiple choice.)

Support for SMB3 multichannel features that take full advantage of client-side multi-core CPUs and bandwidth resources to dramatically improve performance.

When a hard drive has multiple objects at the same time to write requests, support merged into a large continuous IO, significantly improve system performance.

Internal file system replication, without having to go through the client directly in the system to complete high-speed

Supports 10GE and PCIE networking, providing high performance through high-speed internode interconnection and reducing system internal delay.

152. Assuming a customer's initial backup capacity of 1TB, theaverage daily data increment of 10G, with a backup strategy of once a week for all the equipment once a day from Tuesday to Sunday.

All reserve and additional backup data are stored for 4 weeks, regardless of deduplication/redundancy ratio/replication,etc. Calculate the required back-end.

The capacity should not be less than ______. This 1TB is calculated according to 1000G.

4940G

4280G

5940G

5280G

153. Which of the following description is correct about simpana backup software snapshot? (Multiple choice.)

Pause the app before the snapshot, go to the hardware storage snapshot to trigger a common snapshot with application consistency.

Backup software snapshot function can automatically find the storage volumeof the file system, database, mail system.

Background snapshots can be indexed to ensure application recovery and small particle recovery.

Snapshots backup can be offline, the backup server almost has no impact.

154. When planning an active-active disaster recovery solution, the business end adopts the cluster application.

Which of the following clusters is the application cluster?

mSCS

Oracle RAC

HACMP

SQL server

155. Which ofthe following is correct about Huawei OceanStor v3 unified storage system? (Multiple choice.)

Standalone SAN engine and stand-alone file engine

Parallel dual-stack by way of parallel support (SAN) and file system (NAS)

Use unified storage pool technology

file system can achieve deduplication data compression function

156. Disaster recovery project information research mainly includes information about who, what, and why.

What is the followinginformation background? (multiple choice)

A bank has more than XX customers and XX corporate customers.

Data loss will be huge and business disruption may result in significant financial loss.

Business interruption has a huge impact, and the interruption time in business deployment is less than 2 hours.

Clients want to build two live-action data centers in the same city to realize the key business activities such as RTO 2.

157. An enterprise buys a set ofHuawei OceanStor 9000 storage systems. Some of the enterprise's

basic software is stored in a directory, and users can access enjoy/it. In order to facilitate the operation, users should not enter the account password, and the basic software directory is set to NFS enjoy, you should check the share of the "guest enabled" option.

True

False

158. In preparation for disaster recovery design, which of the following is correct?

Use the same type of disk as the master

Raid should be set the same as the master

The capacity of Lun and primary LUN is the same

Use the same number of disks as the master

159. Which statement about the RMAN restore andrecovery is wrong?

Restore (restore) refers to the previously generated backup set, get one or more objects, and then set to restore these objects.

Recovery (recovery) is a database that is consistent with the given point in time to ensure that thisdatabase can be opened.

Usually restored content lags behind the latest database SCN, so you need to ensure consistency through the restoration of the database.

The restored data files can use archived logs and online logs to complete the recovery.

160. Huawei Oceanstor 9000 provides a single file system to the outside through the unified file system namespace management.

Which of the following description is correct? (Multiple choice.)

The namespace isautomatically created when HUAWEI OceanStor 9000 is started with the same name as the system namespace.

Namespaces as the root directory of the entire system can not be shared and visited, only if ask the subdirectories below it can be shared and visited.

A unified namespace provide users with a unified storage resource pool to achieve the centralized management of storage space and distribution.

Each file share directory is a subdirectory of the namespace.
