Test Yourself – 5 CompTIA A+ Questions
Try to answer all questions before checking the explanations below.
Question 1
A technician is troubleshooting slow connectivity to a remote server. Users report high latency, and the technician needs to identify which hop in the path is causing delays.
Which command should be used?
- ping
- tracert
- curl
- netstat
Question 2
A Windows workstation can access local network resources but cannot reach external websites. The technician needs to verify the system’s gateway and DNS configuration.
Which command should be used?
- ping
- ipconfig
- tracert
- netstat
Question 3
Users experience poor VoIP call quality during peak hours, including delays and choppy audio. The network handles both voice and data traffic.
What should the technician implement?
- Enable Quality of Service (QoS)
- Restart all network devices
- Increase the MTU size
- Disable the firewall
Question 4
A technician suspects wireless interference is causing slow speeds and dropped connections in an office environment. They need to analyze signal strength and channel usage.
Which tool should be used?
- Wi-Fi analyzer
- Cable tester
- Loopback plug
- Tone generator and probe
Question 5
A technician needs to connect to a shared network folder from a Windows machine using the correct path format.
Which path should be used?
- \\server\shared_folder
- \drive\shared
- C:\network\folder
- \proxy\path
Answers and Explanations
Question 1
Correct answer: tracert
Tracert displays each hop between the source and destination and shows latency at each point, helping identify where delays occur.
Ping only shows overall response time and does not reveal where latency happens.
Curl is used for data transfer and does not analyze network paths.
Netstat shows local connections and does not trace routes.
Question 2
Correct answer: ipconfig
Ipconfig displays IP settings including gateway and DNS, which helps diagnose connectivity issues to external networks.
Ping tests connectivity but does not show configuration.
Tracert analyzes paths but not local settings.
Netstat shows connections, not IP configuration.
Question 3
Correct answer: Enable Quality of Service (QoS)
QoS prioritizes VoIP traffic, reducing latency and improving call quality during congestion.
Restarting devices is temporary and not a real fix.
Increasing MTU does not address voice traffic priority.
Disabling firewall reduces security and does not solve VoIP issues.
Question 4
Correct answer: Wi-Fi analyzer
A Wi-Fi analyzer identifies interference, channel congestion, and signal strength issues.
Cable tester is for wired connections.
Loopback plug tests ports, not wireless signals.
Tone generator traces cables only.
Question 5
Correct Answer: \server\shared_folder
\server\shared_folder: Network resources are accessed using
UNC paths, which follow this format.
Incorrect Answers:
\drive\shared: Incorrect UNC format.
C:\network\folder: Refers to a local directory path, not a network
path.
\proxy\path: Incorrect terminology; proxies route traffic, not
provide shared network folders.
