1. What is the primary purpose of an enterprise storage array?
A. To provide centralized data storage and access
B. To replace all network switches
C. To manage employee payroll
D. To provide desktop operating systems
Answer: A. To provide centralized data storage and access
Rationale: Storage arrays provide shared, reliable, and
manageable storage resources to applications and hosts.
2. Which type of storage typically presents volumes or LUNs to
servers?
A. Object storage
B. Block storage
C. File storage only
D. Tape storage
Answer: B. Block storage
Rationale: Block storage provides raw block devices that hosts
can format and use as file systems or databases.
,3. What does SAN stand for?
A. Storage Application Network
B. Secure Array Node
C. Storage Area Network
D. System Access Network
Answer: C. Storage Area Network
Rationale: A SAN is a dedicated network infrastructure used to
provide block-level storage connectivity.
4. Which protocol is commonly associated with Fibre Channel
SANs?
A. FC
B. HTTP
C. SMTP
D. DNS
Answer: A. FC
Rationale: Fibre Channel is a high-speed protocol commonly
used for enterprise block-storage connectivity.
5. What is iSCSI primarily used for?
A. Providing block storage over IP networks
B. Encrypting email
,C. Managing DNS
D. Providing wireless connectivity
Answer: A. Providing block storage over IP networks
Rationale: iSCSI encapsulates SCSI commands and transports
them over TCP/IP networks.
6. In storage terminology, what is a volume?
A. A logical storage unit presented to a host
B. A physical network cable
C. A server CPU
D. A backup administrator
Answer: A. A logical storage unit presented to a host
Rationale: Volumes provide logical storage capacity that hosts
can access.
7. What is the primary role of a storage controller?
A. Process and manage storage I/O
B. Manage employee accounts
C. Create websites
D. Replace network firewalls
Answer: A. Process and manage storage I/O
Rationale: Controllers handle communication between hosts
and storage media and perform storage-management
operations.
, 8. What is IOPS?
A. Input/output operations per second
B. Internal operating power system
C. Internet output processing service
D. Integrated object protection system
Answer: A. Input/output operations per second
Rationale: IOPS measures the number of input/output
operations a storage system performs per second.
9. What does storage latency measure?
A. The time required to complete an I/O operation
B. Total storage capacity
C. Number of administrators
D. Number of storage volumes
Answer: A. The time required to complete an I/O operation
Rationale: Lower latency generally means storage requests are
completed more quickly.
10. What does throughput generally describe in storage
systems?
A. Amount of data transferred over time
B. Number of administrators
