Actual exam question from CompTIA's CS0-002

Question #: 90
Topic #: 1

A security administrator needs to provide access from partners to an isolated laboratory network inside an organization that meets the following requirements:
* The partners' PCs must not connect directly to the laboratory network
* The tools the partners need to access while on the laboratory network must be available to all partners
* The partners must be able to run analyses on the laboratory network, which may take hours to complete
Which of the following capabilities will MOST likely meet the security objectives of the request?

A. Deployment of a jump box to allow access to the laboratory network and use of VDI in persistent mode to provide the necessary tools for analysis
B. Deployment of a firewall to allow access to the laboratory network and use of VDI in non-persistent mode to provide the necessary tools for analysis
C. Deployment of a firewall to allow access to the laboratory network and use of VDI in persistent mode to provide the necessary tools for analysis
D. Deployment of a jump box to allow access to the laboratory network and use of VDI in non-persistent mode to provide the necessary tools for analysis

Selected Answer: A

A. Option A meets the requirement that partners' PCs must not connect directly to the laboratory network by using a jump box as an intermediary. Using a VDI in persistent mode provides partners with access to the necessary tools for analysis, while also allowing for the long-running analyses to continue uninterrupted. This option also meets the requirement that the tools must be available to all partners.

A VDI can operate in two modes: persistent and non-persistent. In persistent mode, each user has a dedicated virtual desktop that retains its settings and data across sessions. In non-persistent mode, each user has a temporary virtual desktop that is deleted or reset after each session3. In this scenario, deploying a jump box to allow access to the laboratory network and using VDI in non-persistent mode can meet the security objectives of the request. The jump box can prevent the partners’ PCs from connecting directly to the laboratory network and reduce the risk of unauthorized access or compromise. The VDI in non-persistent mode can provide the necessary tools for analysis without storing any data on the partners’ PCs or the virtual desktops. The VDI in non-persistent mode can also allow the partners to run long analyses without losing their progress or results.

Non-Persistent VDI: Non-persistent VDI means that the virtual desktops are temporary and reset to a known clean state after each use. This is ideal for security because it ensures that no changes or potential compromises persist between sessions. Any malware or unwanted changes are discarded upon logoff, maintaining a clean environment.
