220-1102 Question 105
Single answerpingA help desk technician is troubleshooting a Windows laptop that cannot open the company's internal web portal at intranet.corp.local. The user can browse public websites without issue. The technician wants to quickly verify basic IP connectivity to the internal server before checking browser settings or the web service itself. Which command should the technician run first?
- A
ping intranet.corp.local
- B
ipconfig /release
- C
format c:
- D
net use \intranet.corp.local\share
Show answer and explanation
Correct answer: A
Explanation
The best first command is ping intranet.corp.local because it is a quick, low-impact way to test basic host reachability and name resolution during troubleshooting. In a real A+ Core 2 scenario, technicians commonly start with the least disruptive checks to isolate whether the problem is network-related or application-specific. If ping succeeds, the issue may be with the web service, browser configuration, proxy settings, firewall rules, or the portal itself. If ping fails with a name resolution error, DNS may be the problem. If it resolves but times out, routing, firewall policy, or host availability may be involved. As a best practice, remember that some hosts block ICMP, so a failed ping does not always prove the server is down; it simply means ping is an appropriate first test for basic connectivity. This aligns with standard troubleshooting methodology and common use of ping documented in operating system networking tools and administrative guidance from Microsoft.
- A. Correct.
Correct. Running ping against the hostname is an appropriate first step to test whether the client can resolve the server name and reach it over the network at a basic level using ICMP echo requests. If the hostname resolves and replies are received, the technician knows there is at least basic connectivity to the target. Even if the web portal still does not load, this helps narrow the issue to the application, browser, or web service rather than general network reachability.
- B. Incorrect.
Incorrect. ipconfig /release drops the system's current DHCP-assigned IPv4 address. This is a remediation step that can temporarily disrupt connectivity and is not the best first command to verify whether the internal server is reachable. A technician should gather evidence with non-disruptive tests first.
- C. Incorrect.
Incorrect. format c: would erase the primary drive and is unrelated to diagnosing access to an internal web portal. This is not a network troubleshooting step and would be destructive.
- D. Incorrect.
Incorrect. net use is used to connect to shared network resources such as SMB file shares. It does not directly test whether a web server is reachable for HTTP/HTTPS access, and it assumes a file-sharing service exists on the target. A candidate might choose this if confusing web access with file sharing.
