Section A: Lab Environment Setup & GNS3 Navigation
Q1: A student logs into the WGU learning environment and needs to launch the
simulated network for the D412 course. To start the GNS3 project and power on all
virtual devices, which action should the student take?
A. Click the Red X button and select NO to start devices individually.
B. Click the Yellow Pause button to resume all suspended devices.
C. Click the GREEN Arrow to start, then click YES to start all devices. [CORRECT]
D. Click the Blue Stop button to reset all device configurations.
Correct Answer: C
Rationale: The GNS3 project is started by clicking the GREEN Arrow and confirming YES
to start all devices. The Red X (A) stops devices; the Yellow Pause (B) suspends; the
Blue Stop (D) halts rather than initiates the topology.
Q2: To access the Windows virtual machine that hosts the GNS3 client interface, which
option should the student select from the VM drop-down menu?
A. WGU-Win10-Standard
,B. WGU-Linux-GNS3
C. WGU-Win10-GNS3 [CORRECT]
D. WGU-Server-2019-Base
Correct Answer: C
Rationale: The student must select WGU-Win10-GNS3 from the VM drop-down to
access the GNS3 desktop client. The other VM names (A, B, D) are not the designated
GNS3 client machine for this course.
Q3: After double-clicking the GNS3 icon on the desktop, a Setup Wizard pop-up appears.
According to the lab instructions, what should the student do?
A. Complete all wizard steps to configure a new local server.
B. Restart the VM and attempt to launch GNS3 again.
C. Click Cancel. [CORRECT]
D. Click Finish and proceed through all default settings.
Correct Answer: C
Rationale: The lab instructions explicitly state to click Cancel if the Setup Wizard
appears. Completing the wizard (A, D) or restarting (B) is unnecessary and may delay
access to the pre-configured WGU-Sandbox project.
Q4: Once inside the GNS3 client, the student needs to navigate to different project views
and device lists. Which interface element is used for this navigation?
, A. The gear icon in the bottom-right corner.
B. The search bar in the center of the topology canvas.
C. The hamburger icon in the top-left corner. [CORRECT]
D. The right-click context menu on the desktop background only.
Correct Answer: C
Rationale: The hamburger icon in the top-left corner opens the navigation menu in
GNS3. The gear icon (A) typically opens settings; the search bar (B) is not the primary
navigation method; the desktop context menu (D) does not provide project navigation.
Q5: The WGU-Sandbox project contains a simulated network topology with multiple
device types. Which device serves as the firewall in this environment?
A. Cisco ASA
B. pfSense
C. OPNsense [CORRECT]
D. FortiGate
Correct Answer: C
Rationale: The WGU-Sandbox topology uses OPNsense as the firewall. Cisco ASA (A),
pfSense (B), and FortiGate (D) are not the firewall platform specified for this lab
environment.
