1. A server administrator is deploying a new server that will host a
database requiring very high IOPS and extremely low latency. The
database will also generate a large number of random read/write
operations. Which storage technology would BEST satisfy these
requirements?
A. 7,200 RPM SATA HDD
B. 10,000 RPM SAS HDD
C. NVMe SSD
D. LTO tape drive
Answer: C. NVMe SSD
Rationale: NVMe SSDs communicate over PCIe rather than
traditional SATA or SAS storage interfaces. They provide extremely
high IOPS, low latency, and high throughput, making them
particularly appropriate for transactional databases and other
workloads involving intensive random read/write operations. SATA
HDDs and SAS HDDs rely on mechanical components and therefore
have substantially higher latency. LTO tape is intended primarily for
backup and archival purposes rather than active database workloads.
2. A server contains four identical disks. The administrator wants
redundancy against a single disk failure while maintaining better
1
,read performance than a single disk. Which RAID configuration is
MOST appropriate?
A. RAID 0
B. RAID 1
C. RAID 5
D. RAID 10
Answer: C. RAID 5
Rationale: RAID 5 uses block-level striping with distributed parity and
requires at least three disks. It can tolerate the failure of one disk
while providing improved read performance through striping. RAID 0
provides no fault tolerance. RAID 1 mirrors data and generally
requires an even number of disks, while RAID 10 combines mirroring
and striping but requires at least four disks and provides excellent
performance at the cost of 50% usable capacity.
3. A company needs maximum disk performance and does not care
about data redundancy because the data can easily be regenerated.
Which RAID level should the administrator select?
A. RAID 0
B. RAID 1
C. RAID 5
D. RAID 6
Answer: A. RAID 0
Rationale: RAID 0 stripes data across multiple disks without parity or
mirroring. This provides excellent read/write performance and uses
nearly all available disk capacity. However, if any disk fails, the entire
RAID 0 array becomes unusable. It should therefore only be used
when performance is more important than availability and the
underlying data can be recreated or restored.

,4. A server administrator needs a RAID configuration capable of
surviving two simultaneous disk failures. Which RAID level
provides this capability?
A. RAID 0
B. RAID 1
C. RAID 5
D. RAID 6
Answer: D. RAID 6
Rationale: RAID 6 uses dual distributed parity and can tolerate the
failure of two disks in the array without losing data. RAID 5 can
tolerate only one disk failure. RAID 0 has no redundancy, while RAID
1 provides mirroring rather than dual-parity protection. RAID 6 is
particularly useful for large-capacity arrays where the probability and
impact of multiple disk failures during rebuilds are significant.
5. A server administrator wants to combine disk mirroring with disk
striping to achieve high performance and fault tolerance. Which
RAID level should be used?
A. RAID 0
B. RAID 1
C. RAID 5
D. RAID 10
Answer: D. RAID 10
Rationale: RAID 10 combines RAID 1 mirroring with RAID 0
striping. Data is mirrored between pairs of disks and then striped
across those mirrored pairs. This provides strong read/write
performance and redundancy. RAID 10 normally requires at least four
3
, drives and sacrifices approximately 50% of raw storage capacity for
redundancy.
6. A server suddenly becomes unavailable. Monitoring shows that
the operating system is functioning, but users cannot connect to the
application. The administrator discovers that the server's network
interface is down. Which troubleshooting action should be
performed FIRST?
A. Reinstall the operating system
B. Replace the server motherboard
C. Check the network cable, switch port, and NIC status
D. Format the application database
Answer: C. Check the network cable, switch port, and NIC status
Rationale: Troubleshooting should begin with the simplest and least
invasive possibilities. A disconnected cable, disabled NIC, failed switch
port, or incorrect interface state can immediately explain the
connectivity failure. Reinstalling the operating system or replacing the
motherboard would be excessive before basic physical and interface
checks are completed.
7. Which protocol is primarily used to securely synchronize time
between systems?
A. NTP
B. FTP
C. SMTP
D. SNMP
Answer: A. NTP
