CompTIA SK0-005 Sample Question Answers
Question # 1
A technician is troubleshooting a database server that has 12 external disk arrays. Multiple disks arein a degraded state. The server is in a remote colocation facility and has on-site support. Thetechnician notices all of the external storage arrays are degraded, but the internal arrays arefunctional. Which of the following steps should the technician take next to quickly address this issue?
A. Notify the users of the downtime and reboot the server from the RDP connection. B. Notify the management team about the issue and travel to the colocation site with spare disks andRAID controllers. C. Access the server with RDP and start the RAID utility software to rebuild the arrays. D. Restore the data for the affected disks and notify the users of the estimated recovery time.
Answer: C
Explanation:
Comprehensive and Detailed
The external disk arrays being in a degraded state suggests a RAID failure or a communication issue
with the storage system.
The quickest and most effective solution is to access the RAID utility software remotely via Remote
Desktop Protocol (RDP) to diagnose and potentially rebuild the degraded arrays.
This avoids unnecessary downtime and delays caused by traveling to the site before attempting
remote troubleshooting.
If the RAID utility shows disk failures, the technician can coordinate with on-site staff for further
action, such as replacing failed drives or performing additional recovery steps.

Question # 2
A technician notices a server that contains four fans is now louder than normal even though thetemperature in the room has not changed and the load on the server has not increased. Which of thefollowing is most likely the cause of the noise?
A. Defective fan B. Change in UEFI C. Unseated drive D. Firmware upgrade needed
Answer: A
Explanation:
Comprehensive and Detailed
A sudden increase in fan noise without any changes in temperature or server workload is typically
due to a defective fan.
If one fan fails, the remaining fans will automatically increase their speed to compensate for the loss,
leading to increased noise levels.
Servers use intelligent fan control systems, which monitor temperature and fan health. If a fan stops
functioning properly, the others will ramp up to maintain adequate cooling.
This issue can be resolved by inspecting and replacing the defective fan to restore normal cooling
operation.

Question # 3
A recently deployed server is experiencing significant connection issues after being plugged into thenetwork switch. An administrator was asked to review the server configuration and finds thefollowing:10Gb server NIC with 50-micron optic installed10m single-mode fiber patch cable to the switch10Gb switch interface with short-range optic installedWhich of the following steps should the administrator take next?
A. Replace the switch optic with one that supports MMF B. Replace the server NIC with one compatible with single-mode fiber C. Replace the optic in the server with a short-range optic D. Replace the fiber cable with a 32.8ft (10m) OM4 cable
Answer: A
Explanation:
Comprehensive and Detailed
The server's NIC is equipped with a 50-micron optic, indicating it is designed for multimode fiber
(MMF). However, the current setup uses a single-mode fiber (SMF) patch cable. To resolve the
connectivity issue, the administrator should replace the switch's optic module with one that supports
MMF, ensuring compatibility between the server NIC and the network infrastructure.
Question # 4
A server administrator needs to ensure proprietary data does not leave the company. Which of thefollowing should the administrator implement to meet this requirement?
A. A review of users' activities B. File-level monitoring C. A SIEM solution D. A DLP policy
Answer: D
Explanation:
Comprehensive and Detailed
Data Loss Prevention (DLP) policies are designed to detect and prevent unauthorized transmission of
sensitive data outside the organization. Implementing DLP helps monitor and control data flows,
ensuring proprietary information remains within the company.
Question # 5
Which of the following technologies best describes Hyper-V Replica?
Hyper-V Replica is a feature in Microsoft's Hyper-V virtualization platform that enables asynchronous
replication of virtual machines to a secondary location. This technology is primarily designed for
disaster recovery scenarios, allowing organizations to restore services in the event of site failures.
Question # 6
A technician receives reports that a file server is performing slower than usual after a power failure.While investigating the issue, the technician discovers the write cache was disabled. The technicianchecks a server configuration document and confirms the cache was previously enabled. Which ofthe following events most likely caused this change?
A.The cache hit rate was high B.The volume reached 100% capacity C.The RAID controller battery failed D.A drive in the array was replaced
Answer: C
Explanation:
Comprehensive and Detailed
Write caching improves disk performance by temporarily storing write operations in faster cache
memory before writing to disk. However, to prevent data loss during power failures, write caching
relies on a battery-backed cache. If the RAID controller's battery fails, the system may automatically
disable write caching to protect data integrity, leading to reduced performance.
Question # 7
A technician is installing a large number of servers in a data center with limited rack space. Which of
the following would accomplish this goal while using the least amount of space?
A.Blade enclosure B.Rack balancing C.Rack mount D.Rail kits
Answer: A
Explanation:
Comprehensive and Detailed
Blade enclosures are designed to maximize server density by housing multiple blade servers within a
single chassis. This design minimizes the physical footprint compared to traditional rack-mounted
servers. Key benefits include:
Space Efficiency: Multiple servers share power, cooling, and networking within a compact enclosure.
Simplified Management: Centralized management of power, cooling, and networking simplifies
administration.
Scalability: Easily add or replace blade servers without significant reconfiguration.
Question # 8
Three new servers that use similar types of resources need to be set up, installed with the same OS,and ready within a short time frame. Which of the following installation types would most likely beused?
A.Physical clones B.Bare metal C.Virtualized D.USB
Answer: C
Explanation:
Comprehensive and Detailed
When deploying multiple servers that require similar resources and need to be operational quickly,
virtualization is often the most efficient approach. Virtualization allows for the creation of multiple
virtual machines (VMs) on a single physical server, each running its own instance of an operating
system. This method offers several advantages:
Rapid Deployment: VM templates can be used to quickly deploy standardized server environments,
reducing setup time.
Resource Efficiency: Virtualization enables better utilization of hardware resources by allocating
them dynamically among VMs.
Scalability: Additional virtual servers can be created as needed without the need for additional
physical hardware.
Question # 9
A technician is configuring a server that will need to accommodate a planned network upgrade. Allhosts will be changed from 10Gb copper to 25Gb fiber. Which of the following would best suit therequirements?
A.FCoE B.VLAN ID C.SFP D.HBA
Answer: C
Explanation:
The upgrade involves transitioning from 10Gb copper to 25Gb fiber, which requires appropriate
network interface hardware:
FCoE (A) - Fibre Channel over Ethernet: This protocol allows Fibre Channel to run over Ethernet
networks, but it does not address the physical change from copper to fiber.
VLAN ID (B): VLANs segment networks but do not impact the physical connectivity (copper vs. fiber).
SFP (C) - Small Form-factor Pluggable: SFP transceivers are hot-swappable modules used in network
interfaces to support fiber connections. A 25Gb SFP28 transceiver would be required for the
transition from 10Gb copper to 25Gb fiber. This is the correct answer.
HBA (D) - Host Bus Adapter: HBAs are typically used for storage connectivity (such as Fibre Channel
SANs), not general network upgrades.
Since SFP modules allow servers to support fiber connections, this is the best choice for upgrading
from 10Gb copper to 25Gb fiber.
