File system->Application system->Volume->I/O subsystem->RAID controller->Disk

Application System->File System->Volume->I/O Subsystem->RAID Controller->Disk

Application system->File system->I/O subsystem->Volume->RAID controller->Disk

Application system->File system->Volume->RAID controller->I/O subsystem->Disk

The following description of the characteristics of the LAN-FREE backup method is incorrect:

The backup proxy does not affect the performance of the application server

The backup data stream does not occupy LAN resources

The backup proxy does not affect the performance of the application server

Backup performance is usually higher than LAN-BASED

Does not affect user network performance

Description 1: When Windows mounts a CIFS share with the same IP address (domain name or machine name), the same user can You can mount one or more shares at the same time, but you cannot use different users to mount the same or different shares.Description 2: Windows cannot share multiple Homedir shares with the same IP address (domain name or machine name) The user mounts multiple shares.

Description 1 is correct, description 2 is correct

Description 1 is correct, description 2 is incorrect

Description 1 is wrong, description 2 is correct

Description 1 error, description 2 error

Which of the following descriptions of refactoring is incorrect?

RAID 0,1,3,5,6 and 10 support reconstruction

Reconfiguration does not necessarily require hot spare disks

reconstruction has an impact on RAID performance

Reconstruction will not interrupt RAID business

The dual switch network design is widely used in the FC SAN environment. The following description of the dual switch network redundancy design, Which ones are correct? (Multiple choice)

Deploy two FC switches in a SAN environment to cross connect to the two controllers of the storage device

Each host requires 2 available FC ports, and connects the two ports to different switches

The host port and storage device port on the switch that need to communicate must be in the same zone

Deploy two FC switches in a SAN environment to cross connect to the two controllers of the storage device

Each host requires 2 available FC ports, and connects the two ports to different switches

The host port and storage device port on the switch that need to communicate must be in the same zone

Although there are multiple paths, the dual-switch network only supports link redundancy and does not support load balancing

The following are the key characteristics of cloud computing:

users can self-service on demand

The resource pool used by the user has nothing to do with the exact geographic location of the resource pool

It can quickly and flexibly provide users with capabilities, such as computing power and storage capacity.

Charge based on the actual usage of the user

What is wrong with the following description of NAS? (Multiple choice)

Do not allow the NAS to be accessed by multiple clients at the same time

A client cannot connect to multiple NAS devices at the same time

NAS devices can use cluster technology for failover

NAS provides a centralized management console, which can effectively manage the file system

Do not allow the NAS to be accessed by multiple clients at the same time

A client cannot connect to multiple NAS devices at the same time

Which of the following is not a backup type?

Differential incremental backup

Description 1: FC protocol and FCoE protocol have different operating environments, different operating channels, and the same protocol stack.Description 2: FCoE can only run on 10GE. which solves the problems of short FC transmission distance and packet loss in IP networks.

Description 1 is correct, description 2 is correct

Description 1 is correct, description 2 is incorrect

Description 1 is wrong, description 2 is correct

Description 1 error, description 2 error

The following description of IOPS is wrong:

How many times IO can be performed per second, each IO is fixed according to the size of the written data

If the IO writes a large piece of continuous data every time the channel is changed infrequently, what is done every second at this time IO frequency is relatively low

If the head frequently changes lanes, and the data written each time is relatively large, then the IOPS should be the lowest number of this disk value

If the smallest data block is written each time under the condition of infrequent lane change, such as 512 bytes, then the IOPS will be the highest value

Description 1: A RAID consisting of several hard disks is called a physical volume.Description 2: RAID 5 can improve the read and write rate and provide a certain degree of data security, but when there is a single hard disk failure At this time, read and write performance will be greatly reduced.

The port selected by the IP drift strategy has nothing to do with the port rate, only related to the location of the port, the order of selecting the port Yes?

The port of the local controller

Port at the same position of the remote controller

Ports at other locations of the peer controller

The port of the local controller

Regarding the characteristics of the four disaster recovery modes of active-active, hot standby, warm standby, and cold standby, what is wrong in the following statement?

Hot standby mode requires the highest software cost

The data center using cold standby mode has a long RTO and is unpredictable

The data center adopting the HyperMetro mode has the shortest RTO time

When a data center failure causes the service to become unavailable, the hot standby and activeactive modes can be automatically switched by software Services, while the warm standby mode requires manual intervention, and the cold standby mode requires manual intervention

Hot standby mode requires the highest software cost
