1. What is the primary purpose of enterprise data storage?
A. To increase CPU clock speed
B. To permanently delete unused files
C. To securely store, manage, and retrieve digital data
D. To replace operating systems
Answer: C. To securely store, manage, and retrieve digital data
Rationale: Enterprise storage systems are designed to reliably store,
protect, organize, and provide fast access to business data. CPU speed,
operating systems, and file deletion are unrelated to the primary
purpose of storage infrastructure.
2. Which storage protocol is commonly used for block storage over
Ethernet networks?
,A. NFS
B. SMB
C. iSCSI
D. FTP
Answer: C. iSCSI
Rationale: iSCSI transports SCSI commands over IP networks, enabling
block-level storage across Ethernet. NFS and SMB provide file-level
access, while FTP is used for file transfers rather than storage
connectivity.
3. Which RAID level provides striping with distributed parity?
A. RAID 0
B. RAID 1
C. RAID 5
D. RAID 10
Answer: C. RAID 5
Rationale: RAID 5 distributes parity information across all disks,
providing fault tolerance while improving storage efficiency. RAID 0 has
no redundancy, RAID 1 mirrors data, and RAID 10 combines mirroring
with striping.
,4. Which type of storage provides the fastest access time?
A. Tape storage
B. Hard disk drives (HDDs)
C. Optical discs
D. Solid-state drives (SSDs)
Answer: D. Solid-state drives (SSDs)
Rationale: SSDs use flash memory with no moving parts, resulting in
significantly lower latency and faster performance than HDDs, optical
media, or tape storage.
5. What does SAN stand for?
A. Secure Area Network
B. Storage Area Network
C. Storage Access Node
D. System Archive Network
Answer: B. Storage Area Network
, Rationale: A Storage Area Network is a dedicated high-speed network
that connects servers to block storage devices, improving performance,
scalability, and availability.
6. Which storage type allows multiple clients to access shared files?
A. Block storage
B. Object storage
C. File storage
D. Raw storage
Answer: C. File storage
Rationale: File storage organizes information into files and directories
that multiple users and applications can access simultaneously through
protocols such as NFS and SMB.
7. What is the primary advantage of flash storage over traditional hard
drives?
A. Larger moving components
B. Increased vibration
C. Lower latency and higher performance
D. Greater mechanical reliability requirements
