Question 120
During validation, this problem was found: A standalone window manager opens windows but provides no desired integrated desktop workflow. The original goal was: A low-resource office workstation needs a lightweight complete Linux graphical desktop. Which targeted correction best resolves it?
- Record the actual desktop environment and distinguish it from transport protocols.
- Provide a secured VNC service or equivalent graphical remote desktop mechanism.
- Correct DISPLAY and verify X authorization for the intended session.
- Install and select the intended Xfce desktop session, not just a window manager.
Explanation
Correct Answer
D:Install and select the intended Xfce desktop session, not just a window manager. It directly addresses the observed symptom: A standalone window manager opens windows but provides no desired integrated desktop workflow. The relevant mechanism is A desktop environment integrates panels, session services and common applications; Xfce is commonly lighter than larger suites.
Incorrect Answers
A:This fix is aimed at The inventory labels RDP as the installed graphical desktop environment. and would be relevant if An administrator needs to recognize the difference between GNOME and KDE Plasma on managed Linux desktops. The incident instead states A standalone window manager opens windows but provides no desired integrated desktop workflow. and needs Install and select the intended Xfce desktop session, not just a window manager.
B:This fix is aimed at An SSH-only shell is reachable but no graphical desktop is available to remote operators. and would be relevant if An admin must give remote operators visibility into a graphical session without logging directly into the physical console. The incident instead states A standalone window manager opens windows but provides no desired integrated desktop workflow. and needs Install and select the intended Xfce desktop session, not just a window manager.
C:This fix is aimed at The application connects to the wrong X server because DISPLAY points to an unrelated session. and would be relevant if A remote X11 client must display on the intended workstation X server rather than the local default. The incident instead states A standalone window manager opens windows but provides no desired integrated desktop workflow. and needs Install and select the intended Xfce desktop session, not just a window manager.
Question 121
A Linux administrator faces this requirement: An admin must give remote operators visibility into a graphical session without logging directly into the physical console. Which specific action is the best direct solution?
- Configure a VNC-capable remote desktop service with controlled authentication and transport security.
- Identify GNOME and KDE Plasma as full desktop environments, rather than remote display protocols.
- Evaluate Xfce as the desktop environment rather than installing only a window manager.
- Enable the desktop's screen magnifier for that user.
Explanation
Correct Answer
A:Configure a VNC-capable remote desktop service with controlled authentication and transport security. The mechanism is: VNC transmits desktop framebuffer updates and inputs, unlike SSH text shells; exposed VNC should be protected appropriately.
Incorrect Answers
B:Identify GNOME and KDE Plasma as full desktop environments, rather than remote display protocols. That operation is designed for the different case: An administrator needs to recognize the difference between GNOME and KDE Plasma on managed Linux desktops. It does not perform the specific action required here: Configure a VNC-capable remote desktop service with controlled authentication and transport security.
C:Evaluate Xfce as the desktop environment rather than installing only a window manager. That operation is designed for the different case: A low-resource office workstation needs a lightweight complete Linux graphical desktop. It does not perform the specific action required here: Configure a VNC-capable remote desktop service with controlled authentication and transport security.
D:Enable the desktop's screen magnifier for that user. That operation is designed for the different case: A low-vision operator needs text and UI elements enlarged without requiring others to increase the system-wide resolution. It does not perform the specific action required here: Configure a VNC-capable remote desktop service with controlled authentication and transport security.
Question 122
The engineer proposes this implementation: Configure a VNC-capable remote desktop service with controlled authentication and transport security. The requirement is: An admin must give remote operators visibility into a graphical session without logging directly into the physical console. Which technical explanation best supports the proposed action?
- A desktop environment integrates panels, session services and common applications; Xfce is commonly lighter than larger suites.
- VNC transmits desktop framebuffer updates and inputs, unlike SSH text shells; exposed VNC should be protected appropriately.
- These suites provide session integration and desktop applications; protocols such as RDP describe remote access instead.
- Xorg includes configuration snippets from xorg.conf.d, avoiding edits to unrelated server configuration.
Explanation
Correct Answer
B:VNC transmits desktop framebuffer updates and inputs, unlike SSH text shells; exposed VNC should be protected appropriately. It specifically supports the proposed action of Configure a VNC-capable remote desktop service with controlled authentication and transport security. for the requirement described.
Incorrect Answers
A:This explains another Linux operation, namely Evaluate Xfce as the desktop environment rather than installing only a window manager., where A desktop environment integrates panels, session services and common applications; Xfce is commonly lighter than larger suites.

Question 123
The action Configure a VNC-capable remote desktop service with controlled authentication and transport security. was applied for this goal: An admin must give remote operators visibility into a graphical session without logging directly into the physical console. Which observation provides the most direct acceptance evidence?

Question 129
A Linux administrator faces this requirement: A low-vision operator needs text and UI elements enlarged without requiring others to increase the system-wide resolution. Which specific action is the best direct solution?
- Enable the desktop's screen magnifier for that user.
- Enable Sticky Keys in the desktop's accessibility settings.
