Question 1

What are the main functions of the business continuity solution? (Select All that Apply)



Answer : A, C, D

The main functions of the business continuity solution are to minimize the impact on the business service, ensure zero data loss and zero service interruption, and improve the utilization rate of the disaster recovery equipment. Predicting the disaster occurrence accurately is not a function of the business continuity solution.


Question 2

What are the advantages of SSDs over HDDs? (Select All that Apply)



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.


Question 3

Which of the data storage types are classified based on data access frequency?



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.


Question 4

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



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.


Question 5

Which statement about SCSI is false?



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.


Question 6

Which of the following best describes the relationship between the storage and host in DAS?



Answer : C

In a Direct Attached Storage (DAS) system, the storage and host are connected in a one-to-one relationship. This means that there is a single host and a single storage device, which are both connected directly to each other. This type of storage system is often used when a single host needs access to a large amount of storage, such as in a server or large workstation.


Question 7

Which is the correct order for evolution of mid-range storage architectures?

1) Fixed storage system configuration

2) Dual-controller active-active redundancy configuration

3) Flexible hardware component configuration

4) Flexible software function configuration



Answer : B

The correct order for the evolution of mid-range storage architectures is:

Fixed storage system configuration

Flexible hardware component configuration

Flexible software function configuration

Dual-controller active-active redundancy configuration

In the early stage, storage systems were fixed configurations with little flexibility. As technology progressed, the ability to change hardware components and software functions was added, allowing for more flexibility in the storage system. The last stage is the implementation of dual-controller active-active redundancy configuration, which provides high availability and failover capabilities in case of a hardware failure.
