The following description about CIFS and NFS sharing is incorrect: (multiple choices)

One disadvantage of CIFS is that Windows clients must install professional software

Regardless of the CIFS or NFS protocol, the client needs to convert the file format

CIFS is a protocol based on network sharing, which has high requirements on the reliability of network transmission, so it is usually adopted Transmission using TCP protocol

One disadvantage of CIFS is that Windows clients must install professional software

NFS is a stateless protocol, and CIFS is a stateful protocol. NFS can recover from link failures.Recovery, and CIFS cannot

Regardless of the CIFS or NFS protocol, the client needs to convert the file format

The following two descriptions about cloud computing, Description 1. A deployment model of cloud computing is to divide a large physical server into multiple small virtual machines; Description 2. A deployment model of cloud computing is to aggregate multiple small physical servers into one mainframe.

description 1 and description 2 are correct

Description 1 is correct, description 2 is incorrect

Description 1 is wrong, description 2 is correct

description 1 and description 2 are wrong

Regarding the characteristics of DAS, the following description is correct: (multiple choice)

The number of ports that can be connected to the host is limited

When maintaining internal DAS, the system needs to be powered off

The number of ports that can be connected to the host is limited

When maintaining internal DAS, the system needs to be powered off

If the storage space is tight, the DAS can share the remaining space of the DAS with excess storage resources

When multiple hosts are connected to DAS, they can provide services of different service levels

What is wrong about the snapshot technology below?

When creating a periodic snapshot for the file system, the storage system automatically deletes the earliest created snapshot and automatically generates a new snapshot Photos

When rolling back a file system snapshot, you must cancel the shared mount of the source file system

After opening multiple snapshots on the same file system, roll back to one of the snapshots. After the rollback is complete, the target will be deleted All snapshots after the snapshot creation time

When manually creating a snapshot for a file system, it will not be possible to create a new file system for the file system if it exceeds the product specification limit 'S snapshot

When creating a periodic snapshot for the file system, the storage system automatically deletes the earliest created snapshot and automatically generates a new snapshot Photos

Description 1: HyperMirror has a LUN failure, the host service is not interrupted, the HyperClone primary LUN fails, and the host service is interrupted.Description 2: HyperMirror supports dual copies, HyperClone supports a maximum of 1 master LUN:16 slave LUN mode.

description 1 is correct, description 2 is wrong

description 1 is correct, description 2 is correct

description 1 is correct, description 2 is wrong

description 1 is wrong, description 2 is correct

description 1 is wrong, description 2 is wrong

In data backup and recovery, application testing and data analysis scenarios. HyperClone supports up to 1 master: 8 slave LUN mode. The knowledge points come from HCNA-Storage.0 textbooks and official product documentation.The following descriptions for SAN and NAS are correct: (multiple choices)

SAN is more used in the database scenario to store this structured data.

Now NAS is for unstructured data storage, such as the sharing of key office documents and centralized storage by many department employees. file server.

The characteristic of NAS is to put the file system of the server in the storage, so that the server needs to share data through the network.

SAN is more used in the database scenario to store this structured data.

Now NAS is for unstructured data storage, such as the sharing of key office documents and centralized storage by many department employees. file server.

DAS, NAS, and SAN are all external storage, so storage resource sharing can be easily achieved.

The characteristic of NAS is to put the file system of the server in the storage, so that the server needs to share data through the network.

Compare NAS storage and SAN storage in terms of principle, performance, cost, sharing, and application scenarios. Which of the following descriptions is correct? (Multiple choice)

NAS is a storage device with a file system. Sharing files through the network is equivalent to a host in the network.

SAN is a high-speed fiber-connected disk network. It provides disk resources to the host. It has no file system and is equivalent to a network. A hard drive in the

NAS performance is higher than SAN, cost is higher than SAN

SAN is mainly suitable for file sharing scenarios, sharing is more convenient

NAS is a storage device with a file system. Sharing files through the network is equivalent to a host in the network.

SAN is a high-speed fiber-connected disk network. It provides disk resources to the host. It has no file system and is equivalent to a network. A hard drive in the
