220-1102 exam dumps: questions 101 to 200 of 828

Correct answer: B

• A. Incorrect.

  This is a common mistake. In Windows Command Prompt, using cd with a full path changes directories only within the current drive context. If the technician is already on C:, this command would work, but the scenario asks for the command that switches directly to the target folder before running the script. The more correct and reliable command for changing both drive and directory is cd /d C:\Support\Scripts.

• B. Correct.

  Correct. In Windows Command Prompt, cd /d changes both the current drive and the current directory in one command. This is the best choice when a technician needs to move directly to a folder and ensure the prompt is in the correct location, even if the target path could be on a different drive. It is valid for C: as well and reflects best practice for scripts and remote support work.

• C. Incorrect.

  This is incorrect. chdir is an alias for cd in Command Prompt, but /s is not a valid switch for changing directories. A technician unfamiliar with the proper syntax might guess this option because some commands use switches for recursive or system operations, but cd/chdir does not use /s for this purpose.

• D. Incorrect.

  This is incorrect. cd.. moves up one directory level from the current folder and does not accept a destination path in this format. Someone might choose this option if they confuse moving to a parent directory with navigating to a specific absolute path.

Correct answer: A

• A. Correct.

  Correct. The dir command lists files and folders, and the wildcard *.docx limits the results to Word documents in that folder. The /b switch uses bare format, which displays only filenames and paths without additional metadata such as size or timestamps. This matches the requirement to see only the matching names in the specified directory.

• B. Incorrect.

  Incorrect. This command would search recursively through the folder and all subfolders because of the /s switch. It also does not suppress the normal detailed output, so it would include more information than requested. A technician might choose this option thinking /s means 'show results,' but in dir it means to include subdirectories.

• C. Incorrect.

  Incorrect. The cd command changes the current directory; it does not list files. It also cannot change into a file path such as *.docx. This distractor reflects a common confusion between navigating to a location and displaying the contents of a location.

• D. Incorrect.

  Incorrect. The tree command displays the directory structure and, with /f, can include file names, but it is intended for showing folder hierarchies rather than filtering for a specific file extension in a simple list. It would produce output that is less targeted and more verbose than required.

Correct answer: A

• A. Correct.

  Correct. The scenario shows that local network connectivity and raw internet connectivity are working because the laptop can ping both the default gateway and a public IP address. The failure occurs only when using hostnames, which strongly indicates a name resolution problem. The technician should first verify the DNS settings on the laptop, such as whether the configured DNS server is reachable and correct.

• B. Incorrect.

  Incorrect. If the laptop were connected to the wrong SSID, it would more likely have broader connectivity issues, such as inability to reach internal corporate resources or inconsistent authentication and policy behavior. The scenario states the laptop can access internal resources on the corporate Wi-Fi, so the SSID is likely correct.

• C. Incorrect.

  Incorrect. An incorrect subnet mask commonly causes problems reaching systems outside the local subnet or creates inconsistent routing behavior. In this case, the laptop can successfully reach both the local gateway and a public IP address, which indicates Layer 3 addressing is functioning well enough for routed traffic. That makes the subnet mask a less likely first check than DNS.

• D. Incorrect.

  Incorrect. If the default gateway were missing, the laptop would not normally be able to ping a public IP address on the internet unless the destination happened to be on the same subnet, which is not the case for 8.8.8.8. Since external IP connectivity works, the default gateway is already present and functioning.

Correct answer: A

• A. Correct.

  Correct. "ipconfig /all" displays detailed TCP/IP configuration for each adapter, including the IPv4 address, subnet mask, default gateway, DHCP status, DHCP server, and DNS servers. In this scenario, that is the best first step because it lets you verify whether the laptop received a valid lease or has an APIPA address such as 169.254.x.x.

• B. Incorrect.

  Incorrect. "ipconfig /release" drops the current DHCP lease on DHCP-enabled adapters. That may be useful later if you determine the lease is invalid and want to request a new one, typically followed by "/renew". However, it is not the best first command when you still need to inspect the current configuration.

• C. Incorrect.

  Incorrect. "ipconfig /flushdns" clears the local DNS resolver cache. This can help when a system is resolving hostnames to stale or incorrect addresses, but it does not show the current IP settings and would not help confirm whether the device has a valid DHCP-assigned IPv4 configuration.

• D. Incorrect.

  Incorrect. "ipconfig /displaydns" shows the contents of the local DNS cache. That can be useful for name resolution troubleshooting, but it does not display the adapter's full network configuration such as subnet mask, gateway, or DHCP information.

Correct answer: A

• 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.
