220-1102 exam dumps: questions 801 to 828 of 828

Correct answer: A

• A. Correct.

  Correct. Windows Remote Assistance is designed for support scenarios where a user invites or approves a helper to connect. It allows the technician to view the user's desktop while the user remains logged in, and with permission, the technician can interact with the session. This matches the requirement for active user participation and explicit approval.

• B. Incorrect.

  Incorrect. Remote Desktop is intended to remotely access and control a system by starting a remote session, which typically locks or signs out the local interactive session on Windows client systems. That makes it a poor fit when the end user must stay logged in and collaborate during troubleshooting.

• C. Incorrect.

  Incorrect. SSH provides secure command-line remote access and administration, primarily for text-based management. It does not meet the requirement to view and interact with the employee's graphical desktop in a standard Windows end-user support scenario.

• D. Incorrect.

  Incorrect. FTP is a file transfer protocol used to move files between systems. It does not provide remote screen viewing or remote interactive support capabilities.

Correct answer: A

• A. Correct.

  Correct. "ipconfig /all" displays detailed TCP/IP configuration, including the assigned DNS servers, adapter settings, DHCP information, and other network details. In this scenario, the technician suspects DNS issues after a VPN connection, so confirming which DNS servers are in use is the best first step. From there, the technician could also use related ipconfig commands such as "ipconfig /displaydns" or "ipconfig /flushdns" if cache issues are suspected.

• B. Incorrect.

  Incorrect. "netstat -an" shows active connections and listening ports, which is useful for checking whether sessions are established or whether a system is listening on certain ports. However, it does not directly show which DNS servers are configured on the system, so it is not the best first tool for this DNS-focused scenario.

• C. Incorrect.

  Incorrect. "tracert" helps identify the route packets take to a destination and where delays or failures may occur along the path. While it can help diagnose path-related network issues, it does not provide the configured DNS server information the technician needs first. If name resolution is failing, the technician should verify DNS configuration before tracing routes.

• D. Incorrect.

  Incorrect. "gpupdate /force" refreshes Group Policy settings. Someone might choose this if they suspect a policy-applied network configuration problem, but it is not the most appropriate first step for verifying current DNS settings or checking whether a DNS cache issue is involved.

• E. Incorrect.

  Incorrect. "tasklist" displays running processes. It is helpful for process management and troubleshooting applications, but it has no direct role in identifying configured DNS servers or investigating DNS resolution behavior.

Correct answer: A

• A. Correct.

  Correct. On Windows 10 Pro, Remote Desktop must be enabled on the target PC before it will accept inbound RDP connections. Enabling Remote Desktop also typically configures the required Windows Defender Firewall rules for RDP. Since the technician can already reach the host by name and ping it, the most likely issue is that the PC is not configured to accept Remote Desktop connections.

• B. Incorrect.

  Incorrect. Telnet and TCP port 23 are unrelated to Remote Desktop, which uses RDP over TCP port 3389 by default. A candidate might choose this option if they confuse general remote access tools with RDP-specific requirements.

• C. Incorrect.

  Incorrect. Membership in Power Users does not grant the ability to connect via Remote Desktop. For RDP access, the user must generally be an administrator or a member of the Remote Desktop Users group on the target system. Even then, the PC must still have Remote Desktop enabled first.

• D. Incorrect.

  Incorrect. Disabling Network Level Authentication is not the first step and is not generally recommended unless there is a specific compatibility problem with an older RDP client. The scenario indicates the computer is not accepting connections, which is more consistent with Remote Desktop not being enabled than with an NLA mismatch.

Correct answer: A

• A. Correct.

  Correct. The user can reach an internal resource by IP address but not by server name, which strongly indicates a name resolution issue rather than a general VPN connectivity problem. A common fix is to ensure the VPN connection is assigning or using the organization's internal DNS servers so internal hostnames and intranet records can be resolved properly.

• B. Incorrect.

  Incorrect. A local firewall can block traffic, but in this scenario the user can already reach an internal server by IP address through the VPN tunnel. That means the tunnel is functioning and traffic is passing. The symptom specifically points to DNS/name resolution, not general packet filtering by the local firewall.

• C. Incorrect.

  Incorrect. The home router is unlikely to be the root cause because the VPN is connected and internal hosts are reachable by IP address. If the router were blocking the required traffic broadly, the user would be more likely to have VPN connection failures or no access to internal IP addresses at all. This option reflects a common mistake of blaming the internet connection instead of examining the specific symptom.

• D. Incorrect.

  Incorrect. PPTP is outdated and considered insecure, and switching to it is not an appropriate troubleshooting step for this symptom. The issue is not that the tunnel cannot be established; it is that internal names are not resolving after connection. Best practice is to use secure VPN protocols and correct DNS configuration rather than downgrade security.

Correct answer: A

• A. Correct.

  Correct. VNC is designed for remote desktop sharing and control, allowing a technician to view and interact with the user's graphical desktop in real time. It is commonly used across multiple operating systems, which fits the requirement for cross-platform flexibility. In a support scenario where Remote Desktop host capability is unavailable, VNC is a practical alternative.

• B. Incorrect.

  Incorrect. Microsoft Remote Desktop host capability is generally tied to supported editions such as Windows Pro, Enterprise, or Education. The scenario specifically states the user does not have Windows Pro, so enabling standard Remote Desktop host functionality on that PC is not the appropriate solution. A candidate might choose this because Remote Desktop is a common remote support tool, but the edition limitation makes it unsuitable here.

• C. Incorrect.

  Incorrect. SSH is primarily used for secure command-line remote administration, especially on Linux and network devices. By itself, SSH does not provide the technician with a graphical remote-control session of the user's desktop, which is required in this case. Someone might choose SSH because it is a common remote management protocol, but it does not meet the stated need for desktop viewing and control.

• D. Incorrect.

  Incorrect. Joining a computer to a domain allows centralized management through Group Policy, but it does not by itself provide a remote desktop sharing tool. This option confuses management infrastructure with remote-control technology. A domain could help deploy software such as a VNC server, but domain membership alone does not solve the immediate support need.
