EXOS XPS Prep Exam Questions And Answers with
rationales guaranteed pass latest already graded a+
Question 1:
Which of the following is the most common metric used to measure network performance?
a) CPU Utilization
b) Bandwidth
c) Disk I/O
d) System Uptime
Correct Answer: b) Bandwidth
Rationale:
Bandwidth refers to the maximum rate at which data can be transferred over a network
connection. It's one of the primary metrics used to evaluate network performance. CPU
Utilization, Disk I/O, and System Uptime are important for overall system performance but are
not specifically used to measure network performance.
Question 2:
What does the term "latency" refer to in networking?
a) The amount of data transferred between two systems
b) The time it takes for data to travel from the source to the destination
c) The speed of the data transfer
d) The number of hops in a network path
Correct Answer: b) The time it takes for data to travel from the source to the destination
Rationale:
Latency is the delay between sending a request and receiving a response. It's often measured in
milliseconds (ms) and is a critical factor in network performance, especially for time-sensitive
applications like VoIP or online gaming.
Question 3:

Which of the following tools would you most likely use to analyze network traffic in real-
time?
a) NetFlow
b) Wireshark
c) Top
d) Nagios
Correct Answer: b) Wireshark
Rationale:
Wireshark is a widely-used network protocol analyzer that allows you to capture and inspect
network traffic in real-time. NetFlow is a protocol for collecting traffic data but does not capture
real-time packets like Wireshark. Top is a system monitoring tool, and Nagios is a network
monitoring tool, not specifically designed for packet-level analysis.
Question 4:
What is the main advantage of using a solid-state drive (SSD) over a traditional hard disk
drive (HDD)?
a) Lower storage capacity
b) Faster read/write speeds
c) Higher failure rate
d) Lower cost per GB
Correct Answer: b) Faster read/write speeds
Rationale:
SSDs use flash memory, which allows for faster read and write speeds compared to the spinning
disks of an HDD. This leads to improved system performance, especially when dealing with
heavy disk I/O operations. Although SSDs tend to be more expensive, their speed advantage is
significant.
Question 5:
Which of the following is the best way to reduce CPU utilization on a server?
a) Increase the number of CPU cores
b) Use a load balancer to distribute traffic
c) Increase system RAM
d) Reboot the server
, 3|Page
Correct Answer: b) Use a load balancer to distribute traffic
Rationale:
A load balancer helps distribute incoming network traffic across multiple servers, reducing the
CPU load on any single server. Increasing CPU cores or RAM may improve performance, but
they don't directly address high CPU utilization caused by high traffic. Rebooting doesn't resolve
the underlying issue.
Question 6:
Which of the following best describes the concept of "scalability" in IT systems?
a) The ability to handle increased workload by adding resources
b) The ability to maintain performance during failures
c) The time taken to recover from system crashes
d) The rate of system failures under load
Correct Answer: a) The ability to handle increased workload by adding resources
Rationale:
Scalability refers to the capacity of a system to handle a growing amount of work or its potential
to accommodate growth by adding resources (e.g., CPU, memory, storage, or additional servers).
This can be achieved either vertically (upgrading existing hardware) or horizontally (adding
more servers).
Question 7:
What is the first step in troubleshooting a network performance issue?
a) Check for hardware failures
b) Verify network configuration
c) Identify and isolate the problem
d) Replace network cables
Correct Answer: c) Identify and isolate the problem
Rationale:
Effective troubleshooting starts with identifying and isolating the problem. Once the issue is
understood, steps like checking configurations, verifying hardware, or replacing cables can be
applied. Jumping straight into replacing components without understanding the problem could
lead to unnecessary work or missed diagnoses.
