Question 6 of 237
Which of the following security devices is presented to indicate some feat of service, a special accomplishment, a symbol of authority granted by taking an oath, a sign of legitimate employment or student status, or as a simple means of identification?
Answer

Suggested Answer

The suggested answer is D.

A badge is presented to indicate some feat of service, a special accomplishment, a symbol of authority granted by taking an oath, a sign of legitimate employment or student status, or as a means of identification. It serves as both an identifier and an acknowledgment of a person's status within an organization or institution. Sensors, alarms, and motion detectors are devices primarily used to detect and alert in case of security breaches, not as identifiers.

Mark works as a Network Administrator for NetTech Inc. He wants users to access only those resources that are required for them. Which of the following access control models will he use?
Answer

Suggested Answer

The suggested answer is D.

Role-Based Access Control (RBAC) is the most suitable access control model for Mark's objective. In RBAC, access permissions are assigned based on the roles within an organization. Each role has specific permissions, and users are assigned these roles according to their job functions. This model allows for systematic and consistent access control, ensuring that users can only access the resources necessary for their roles, which aligns with Mark's requirement.

IPsec VPN provides a high degree of data privacy by establishing trust points between communicating devices and data encryption. Which of the following encryption methods does IPsec VPN use? Each correct answer represents a complete solution. Choose two.
Answer

Suggested Answer

The suggested answer is C, D.

IPsec VPN uses AES (Advanced Encryption Standard) and 3DES (Triple Data Encryption Standard) for encryption. AES is widely used for its efficiency and security, while 3DES is another robust encryption method although it's considered less efficient compared to AES. Therefore, these two encryption methods are correct as they are both applicable to IPsec VPN.
