220-1102 Question 255
Single answerpingA help desk technician is troubleshooting a Windows laptop that cannot open the company's internal ticketing website at intranet.corp.local. The user confirms they can browse external websites. The technician wants to quickly verify whether the laptop can reach the ticketing server over the network before investigating DNS or browser issues. Which command should the technician use first?
- A
ping intranet.corp.local
- B
ipconfig /release
- C
format intranet.corp.local
- D
net user intranet.corp.local
Show answer and explanation
Correct answer: A
Explanation
For A+ Core 2 troubleshooting, ping is a standard first-step tool for checking basic host reachability. In a real-world support scenario, if a user can access external sites but not an internal site, a technician may first use ping to determine whether the target host responds and whether the hostname resolves. This helps narrow the issue to general connectivity, name resolution, host availability, or application-level problems. It is important to remember that some servers or firewalls block ICMP echo requests, so a failed ping does not always prove the server is down; however, it remains an appropriate initial test. This aligns with common Windows troubleshooting practice and Microsoft command-line documentation for ping.
- A. Correct.
Correct. The ping command is commonly used as an initial connectivity test to determine whether a host can be reached over an IP network. In this scenario, pinging the server name helps the technician quickly check basic network reachability and also see whether the hostname resolves to an IP address. This is a practical first troubleshooting step before moving on to deeper investigation.
- B. Incorrect.
Incorrect. ipconfig /release drops the current DHCP-assigned IPv4 address on a Windows system. It does not test whether the ticketing server is reachable, and using it first could temporarily worsen connectivity. A technician would normally use release/renew only when specifically troubleshooting local DHCP addressing problems.
- C. Incorrect.
Incorrect. format is a disk utility used to prepare storage media, not a network troubleshooting command. This distractor represents a command-line misuse and would be unrelated to testing access to an internal web server.
- D. Incorrect.
Incorrect. net user is used to manage local or domain user accounts, not to test server connectivity. Someone unfamiliar with command-line tools might confuse administrative commands with network diagnostics, but this command would not help determine whether the laptop can reach the ticketing server.
