The solution needs to allow the technician to see what the user is doing and provide the ability to interact with the user's session. Which of the following remote access technologies would support the use case?  \nA. VPN  \nB. VNC  \nC. SSH  \nD. RDP  \nAnswer: B  \nExplanation:  \nThe correct answer isVNC (Virtual Network Computing) . VNC is a graphical desktop-sharing system that uses the Remote Frame Buffer protocol (RFB) to remotely control another computer. It is platform-independent and widely supported on Linux, which makes it ideal for providinginteractive remote support for a Linux-based operating system. It allows the technician not only to view the remote desktop session but also tocontrol it, fulfilling the need to see and interact with the user’s session.  \nA . VPN(Virtual Private Network) creates a secure tunnel to a network but doesnot provide desktop sharing or session controlby itself.  \nC . SSH(Secure Shell) provides secure command-line access to Unix/Linux systems but does not offergraphical desktop interaction, which is a requirement in this case.  \nD . RDP(Remote Desktop Protocol) is primarily a Microsoft protocol, and although it can be made to work on Linux, it isnot natively supported on legacy Linux systems, and thusless suitablethan VNC in this scenario.  \nCompTIA A+ 220-1102 Core 2 Objective Reference:  \nObjective 1.8 – Given a scenario, use features and tools of the operating system.  \nUnder this objective, candidates are expected to be familiar with remote access technologies, includingRDP, SSH, and VNC, and understand their appropriate uses and limitations on different platforms such as Windows and Linux.  \nQuestion: 2  \nA technician is attempting to join a workstation to a domain but is receiving an error message stating the domain cannot be found. However, the technician is able to ping the server and access the internet. Given the following information:  \nVisit us at: [https://www.examsboost.com/test/220-1202](https://www.examsboost.com/test/220-1202)  \nIP Address – [192.168.1.210](192.168.1.210)[ ](192.168.1.210)Subnet Mask – [255.255.255.0](255.255.255.0)[ ](255.255.255.0)Gateway – [192.168.1.1](192.168.1.1)[ ](192.168.1.1)DNS1 – [8.8.8.8](8.8.8.8)  \nDNS2 – [1.1.1.1](1.1.1.1)  \nServer – [192.168.1.10](192.168.1.10)  \nWhich of the following should the technician do to fix the issue?  \nA. Change the DNS settings.  \nB. Assign a static IP address.  \nC. Configure a subnet mask.  \nD. Update the default gateway.  \nAnswer: A  \nExplanation:  \nThe issue described—“domain cannot be found” despite the ability to ping the server and access the internet—indicates aDNS resolution problem, not a network connectivity issue. The workstation is currently usingpublic DNS servers ([8.8.8.8](8.8.8.8) and [1.1.1.1](1.1.1.1))whichcannot resolve internal domain names, such as the ones used in Active Directory environments. To resolve this, the technician needs tochange the DNS settings to point to the internal DNS server, which inmost domain setups is thedomain controller itself (likely [192.168.1.10](192.168.1.10) in this case) .  \nHere’s the breakdown of the incorrect options:  \nB . Assign a static IP address: The IP is already assigned and functioning; the device can ping and reach the network and internet.  \nC . Configure a subnet mask: The subnet mask is appropriate for the network range (Class C /24) .  \nD . Update the default gateway: The gateway is valid and allows ","cbCaid0NTcp5PtqX","https://ap.wps.com/l/cbCaid0NTcp5PtqX","pdf",410395,"English","# Remote access and interactive session control\n## Selecting VNC vs VPN, SSH, and RDP\n# DNS and domain join troubleshooting\n## Correct DNS server configuration for Active Directory\n# IT change management process\n## First step for end-of-life switch upgrades","[{\"question\":\"For remote support to view and interact with a Linux user session from a Windows laptop, which technology is most appropriate?\",\"answer\":\"VNC.
