Which of the following is not an IP SAN component?

Storage device with iSCSI interface

What is the correct sequence of the overall reconstruction process?

Query all CKGs with CK falling on the faulty disk

Assign hot spare CK to all these CKGs

Update CKG information and release the reconstructed CK

Write the reconstructed data to the hot standby CK

Through the RAID algorithm, calculate the data on the failed disk based on the data on the normal disk and the check disk

What is the function of hot spare in storage?

Spare disk space used for disk data reconstruction when disks are faulty.

Additional space for usage when storage resource is low

Used as cache to increase the performance of disks.

Spare disk space for storing metadata

Spare disk space used for disk data reconstruction when disks are faulty.

During data center construction, a media company purchased storage devices from multiple vendors.The CTO wants to centrally manage these devices through storage virtualization. Which function is NOT provided by storage virtualization?

Enabling servers to directly access storage hardware

Reducing the limitations of physical storage capacity

Hiding the complexity of physical devices

Enabling servers to directly access storage hardware

Supporting unified deployment and management

An engineer maps the storage system to the file server to store various enterprise files. One day, the file system is attacked by viruses and files cannot be opened. To access the files, the engineer performs a snapshot rollback. Which statement is FALSE?

If there are writes to the source LUN during a snapshot rollback, the rollback is performed after the writes are complete.

A snapshot rollback can quickly restore data.

When no host reads or writes data, the snapshot data is rolled back to the source volume in sequence.

Some data may be lost during a snapshot rollback.

If there are writes to the source LUN during a snapshot rollback, the rollback is performed after the writes are complete.

Which statement about SCSI is false?

The evolution is SCSI-1 > SCSI-2 > SCSI-3.

SCSI stands for "Small Computer System Interface". It is a protocol system

SCSI supports communication between different devices.

The latest protocol is SCSI-3, which provides a transmission speed of up to 1 GB/s

The evolution is SCSI-1 > SCSI-2 > SCSI-3.

Which of the following is incorrect regarding the differences of IP SAN and FC SAN?

IP SAN can connect to FC SAN without any additional protocols.

IP SAN uses iSCSI protocol for data transmission.

IP SAN can connect to FC SAN without any additional protocols.

FC SAN uses FC protocol for data transmission

Both encapsulates the SCSI command with their underlying protocol before transmission

Inline compression before data is written to disks

Inline compression and data read when the system is idle

Post-process compression, where data is first written to disks and then read and compressed when the system is idle

Inline compression after data is written to disks
