Question 1643Question

A help desk technician attempts to establish a native remote management session to assist a teleworking employee whose corporate laptop runs Windows 11 Home. The technician needs to interactively troubleshoot a software issue while allowing the employee to view the screen and maintain an active session. However, the technician's incoming connection attempt via standard Remote Desktop (RDP) fails. Which of the following identifies the primary cause of this failure and the most appropriate native tool to resolve the issue?

Show answer & explanation

Answer: Windows 11 Home does not support incoming Remote Desktop server connections; the technician should use Microsoft Remote Assistance (MSRA) or Quick Assist.

Answer

Windows 11 Home edition does not support incoming Remote Desktop (RDP) host capabilities; the technician should use Microsoft Remote Assistance (MSRA) or Quick Assist to view and control the session interactively.
Windows 11 Home edition lacks the host/server functionality required to accept incoming Remote Desktop Protocol (RDP) connections. To provide interactive support where the end-user remains logged in and views the session, Microsoft Remote Assistance (MSRA) or Quick Assist must be used, as both tools are fully supported on Windows Home editions.

Step-by-Step Solution

1
Analyze operating system edition capabilities for remote host access.
Identified that Windows Home editions (including Windows 10/11 Home) support client-side outbound RDP sessions but lack the RDP server component to accept incoming RDP connections.
CompTIA A+ guidelines dictate recognizing feature limitations across Windows editions.
2
Evaluate the technical requirement for interactive support.
The support scenario specifies screen sharing where the end-user remains logged in and observes the technician's actions.
Standard RDP locks out the local user session on desktop Windows versions, whereas MSRA and Quick Assist support concurrent interactive viewing.
3

Which of the following remote access tools is the most appropriate choice to establish this support session?

Show answer & explanation

Answer: Microsoft Remote Assistance / Quick Assist

Answer

Microsoft Remote Assistance / Quick Assist is the correct tool because it is supported on Windows 11 Home edition, allows interactive desktop sharing where both the user and technician view the screen simultaneously, and works across standard NAT routers without custom inbound port forwarding.
Microsoft Remote Assistance / Quick Assist is available across all Windows editions (including Home), permits both the technician and end user to view and interact with the desktop simultaneously, and initiates connections via outbound web protocols that bypass NAT firewalls without requiring custom port forwarding.

Step-by-Step Solution

1
Identify the operating system edition constraints.
The target computer runs Windows 11 Home, which lacks the inbound Remote Desktop host server feature.
Windows Home editions can only originate RDP connections as a client, not host incoming RDP sessions.
2
Analyze the session interaction and network requirements.
The scenario requires shared interactive desktop viewing while the user remains logged in, operating through a home router with default NAT.
The required tool must support GUI screen sharing and initiate outbound connections (or use cloud-brokered relaying) to traverse local NAT firewall settings without port forwarding.

Question 1651Question

A Windows 11 desktop computer experiences severe system corruption. A technician runs System File Checker (`sfc /scannow`), but the process fails with an error stating that corrupt files were found but could not be repaired. Next, the technician attempts to execute `dism /online /cleanup-image /restorehealth`, but the operation fails with error code `0x800f081f`, indicating that the repair source files could not be located because internet access is disabled and the local Side-by-Side (WinSxS) component store is damaged. The technician mounts a verified Windows 11 installation ISO assigned to drive letter `E:`. Which of the following commands must the technician execute to repair the local component store from the mounted ISO while preventing DISM from attempting to access online update servers?

Show answer & explanation

Answer: dism /online /cleanup-image /restorehealth /source:wim:E:\sources\install.wim:1 /limitaccess

Answer

dism /online /cleanup-image /restorehealth /source:wim:E:\sources\install.wim:1 /limitaccess
The correct command utilizes `dism /online /cleanup-image /restorehealth` combined with `/source:wim:E:\sources\install.wim:1` to specify the exact path and image index of a clean Windows WIM file. Including `/limitaccess` prevents DISM from reaching out to online Windows Update servers, allowing successful offline repair of the corrupted WinSxS component store so that `sfc /scannow` can subsequently repair protected system files.

Step-by-Step Solution

1
Identify why SFC and standard DISM failed.
SFC fails when the local component store (WinSxS) is corrupt. Standard online DISM restorehealth fails with error 0x800f081f when local source files are missing and Windows Update is unreachable.
DISM requires a valid source payload to repair the component store before SFC can replace corrupted system files.
2
Specify an offline WIM source file from mounted media.
Using the syntax `/source:wim:E:\sources\install.wim:1` points DISM to index 1 of the install.wim image on the mounted media.
This provides known-good replacement files for damaged components directly from install media.
3
Enforce offline source restriction.
Adding the `/limitaccess` parameter prevents DISM from attempting to query Windows Update or WSUS servers.
Ensures the operation relies strictly on the mounted offline ISO payload.

Question 1652Question

A laboratory systems specialist is troubleshooting a Windows 11 workstation that experiences recurring system crashes following an ungraceful power loss during a feature update. Attempting to execute System File Checker results in an error indicating that Windows Resource Protection could not perform the requested operation due to a corrupted local image payload. Which of the following actions should the specialist perform to successfully repair the component store and verify system file integrity? (Select TWO.)

Select all that apply

Show answer & explanation

Answer: Execute DISM with the /restorehealth parameter from an elevated Command Prompt.; Execute SFC with the /scannow parameter after the servicing image repair finishes successfully.

Answer

Executing DISM with the /restorehealth parameter to repair the component store, followed by executing SFC with the /scannow parameter to restore system file integrity.
When Windows Resource Protection fails to complete an SFC scan due to payload corruption, the Windows Component Store (WinSxS) must be repaired first. Executing DISM with the /restorehealth parameter repairs the component store. Once DISM finishes repairing the store, running SFC with the /scannow parameter allows System File Checker to successfully scan and replace corrupted operating system binaries.

Step-by-Step Solution

1
Diagnose the failure of System File Checker (SFC).
Identify that the Windows Component Store (WinSxS) repository is corrupted, preventing SFC from retrieving good file copies.
SFC depends on a functional component store to perform file replacements.
2
Execute dism /online /cleanup-image /restorehealth in an elevated Command Prompt.
Deployment Image Servicing and Management (DISM) downloads or repairs the local component store payload.
This fixes the underlying source repository needed for system file repair.
3
Execute sfc /scannow in an elevated Command Prompt.
SFC scans protected system files and replaces corrupted binaries using the healthy component store.
This completes the resolution process by restoring missing or corrupted OS files.

Question 1653Question

A field support engineer must access the graphical user interface (GUI) of a remote Linux diagnostic server located at a branch office. The server runs a standard Virtual Network Computing (VNC) service configured to listen on its default port. Corporate security policy prohibits transmitting cleartext management traffic over the public internet and explicitly blocks inbound traffic on TCP port 5900 at the perimeter firewall. Which strategy allows the engineer to establish a secure, policy-compliant graphical session to the remote server?

Show answer & explanation

Answer: Configure an SSH tunnel on TCP port 22 to encrypt traffic and forward the local VNC client connection to the remote server's loopback interface.

Answer

Establish an SSH tunnel over TCP port 22 to encrypt traffic and forward the local VNC viewer connection to the remote server.
Virtual Network Computing (VNC) operates by default over TCP port 5900 without native encryption. When perimeter firewalls block port 5900 and corporate policies require secure communication, technicians use Secure Shell (SSH) port forwarding over TCP port 22. The SSH connection establishes an encrypted tunnel between the client and remote host. The local VNC viewer client connects to a local port, which routes encrypted data through TCP port 22 to the remote Linux server's loopback interface on port 5900.

Step-by-Step Solution

1
Analyze protocol encryption and port security constraints.
Identified that VNC uses TCP port 5900 and transmits data unencrypted by default, which is blocked by the perimeter firewall and violates security policy.
Cleartext protocols transmitted across public networks present severe eavesdropping and credential theft risks.
2
Evaluate secure tunneling capabilities of allowed management protocols.
Selected Secure Shell (SSH) operating on TCP port 22, which provides strong public-key/symmetric encryption and port forwarding functionality.
SSH tunneling allows secondary protocol payloads (such as TCP port 5900 VNC traffic) to be safely encapsulated within an encrypted SSH transport stream.
3
Establish the remote access architecture.
Created an SSH tunnel forwarding local port traffic to localhost:5900 on the destination server, allowing the VNC viewer client to connect securely.
This configuration satisfies both firewall rules (allowing only TCP 22 inbound) and policy requirements for full encryption.

A network administrator needs to establish a remote command-line session to configure a network router. Which remote access protocol should the administrator select to ensure that all session data, including login credentials, is encrypted?

Show answer & explanation

Answer: Secure Shell (SSH)

Answer

Secure Shell (SSH)
Secure Shell (SSH) encrypts all command-line communication, including login credentials and commands, preventing unauthorized interception during remote network administration.

Step-by-Step Solution

1
Identify the primary requirement from the scenario: encrypted remote command-line access to a router.
The solution must support a text-based interface and enforce end-to-end encryption for authentication and commands.
Transmitting management credentials in clear text over a network creates severe security risks.
2
Compare available remote access protocols against interface and security requirements.
SSH provides secure, encrypted CLI access over TCP port 22. Telnet provides unencrypted CLI access, while RDP and VNC provide graphical interfaces.
SSH is the standard secure protocol for remote command-line device administration.

Question 1656Question

A desktop support specialist is servicing a Windows 11 client workstation that lost power during a major system update. System File Checker (`sfc /scannow`) completes with an error stating that Windows Resource Protection found corrupt files but was unable to fix some of them because the local Component Store (WinSxS) is corrupted. The workstation is connected to an internal network with access to a shared repository containing an offline Windows installation file at `\\deploy\share\install.wim`, but it does not have public internet access to reach Windows Update. Which of the following DISM commands should the specialist run first to repair the component store using the internal repository?

Show answer & explanation

Answer: dism /online /cleanup-image /restorehealth /source:wim:\\deploy\share\install.wim:1 /limitaccess

Answer

Execute `dism /online /cleanup-image /restorehealth /source:wim:\\deploy\share\install.wim:1 /limitaccess` to repair the corrupted Windows Component Store using the specified local WIM image.
When System File Checker fails because the local Component Store is corrupt, DISM (`/restorehealth`) must be executed to repair the store first. In environment configurations where public internet access is restricted or unavailable, the `/source` flag points to a valid Windows installation media (such as an `install.wim` image), and the `/limitaccess` switch prevents DISM from attempting to contact Windows Update.

Step-by-Step Solution

1
Identify the cause of SFC failure
System File Checker (`sfc`) failed because the local backup source (WinSxS Component Store) is corrupt.
SFC relies on a healthy Component Store to pull replacement system files.
2
Formulate the DISM repair command targeting an offline source
Use `dism /online /cleanup-image /restorehealth` along with `/source` specifying the network WIM path and index number.
The system lacks internet access, so DISM must be directed to an internal WIM file.
3
Append the `/limitaccess` switch to the DISM command
DISM is blocked from trying to reach Windows Update servers over the internet.
Without `/limitaccess`, DISM will time out attempting to connect to public Microsoft servers.
4
Re-run System File Checker (`sfc /scannow`)
SFC successfully repairs operating system files using the restored Component Store.
With the WinSxS store healthy, SFC has valid reference copies to replace damaged OS binaries.
