Answer : B, D

A failover group is a combination of ports that are used for IP address failover in a storage system, and IP address failover ensures service continuity and improves the reliability of paths for accessing file systems. IP address failover applies to all storage network architectures, not just IP SAN. Fallback means that the standby port takes over services when the active port fails, and then the active port takes over services again after it recovers.

Answer : B, C, D

The correct answers are B. Better environmental adaptability, C. Faster read/write speed for random access, and D. Longer service life. SSDs (solid-state drives) offer several advantages over HDDs (hard disk drives), including better environmental adaptability, faster read/write speed for random access, lower power consumption, and a longer service life. SSDs also tend to have smaller form factors, making them ideal for many mobile applications. However, HDDs typically offer larger capacity than SSDs.

Solid-state drives (SSDs) are a type of data storage device that have several advantages over hard disk drives (HDDs).

Better environmental adaptability: SSDs are not affected by temperature, humidity, or altitude changes, and they are more resistant to shock and vibration than HDDs.

Faster read/write speed for random access: SSDs have no moving parts, which means that data can be read and written much faster than on HDDs, especially for random access to small files.

Longer service life: SSDs have no moving parts, so they are less likely to fail due to mechanical issues. They also have a higher maximum read/write cycle than HDDs, which means that they can handle more write operations over their lifetime.

Larger capacity: SSDs are not always have larger capacity than HDDs, it depends on the specific model and brand.

Answer : A, C, D

Nearline storage is a type of data storage that is classified based on data access frequency, with online storage being for frequent access, nearline storage for occasional access, and offline storage for rare access. Unified storage combines the features of online, nearline and offline storage into a single solution.

Answer : B

IP SAN and FC SAN are different types of storage area networks (SANs) that use different protocols for data transmission.

IP SAN uses the iSCSI protocol for data transmission. It is a block-level protocol that allows data to be transferred over IP networks and it allows to connect hosts and storage systems over long distances using standard Ethernet networks.

FC SAN uses the Fibre Channel (FC) protocol for data transmission. It is a dedicated protocol that uses a dedicated cabling and a specialized switch infrastructure to connect hosts and storage systems.

Both IP SAN and FC SAN encapsulate the SCSI command with their underlying protocol before transmission, but they cannot connect to each other without additional protocols such as Fibre Channel over IP (FCIP) or Internet SCSI (iSCSI) which are used to tunnel Fibre Channel or iSCSI over an IP network.

Answer : D

The evolution is SCSI-1 > SCSI-2 > SCSI-3. SCSI stands for 'Small Computer System Interface', and it is a protocol system that supports communication between different devices. The latest protocol is SCSI-3, which provides a transmission speed of up to 1 GB/s. The evolution of SCSI is SCSI-1 > SCSI-2 > SCSI-4 > SCSI-3.
