100-160 Question 99
Select 3A company has implemented a secure remote access solution for its employees working from home. They want to ensure that only authorized devices and users can connect to the corporate network. Which of the following technologies should be implemented to achieve this goal?
- A
Multi-Factor Authentication (MFA)
- B
Virtual Private Network (VPN)
- C
Network Access Control (NAC)
- D
Simple Network Management Protocol (SNMP)
- E
Single Sign-On (SSO)
Show answer and explanation
Correct answers: A, B, C
Explanation
To implement secure access technologies for remote work, it's essential to use a combination of authentication and network security controls. MFA ensures user identity verification, VPN provides secure communication, and NAC validates device compliance with security policies. SNMP and SSO, while useful in other contexts, do not directly secure access to the network.
- A. Correct.
Multi-Factor Authentication (MFA) adds an additional layer of security by requiring users to provide two or more forms of verification, ensuring only authorized users can gain access.
- B. Correct.
Virtual Private Network (VPN) creates an encrypted tunnel for secure remote access to the corporate network, protecting data in transit.
- C. Correct.
Network Access Control (NAC) ensures that only authorized devices meeting specific security criteria can connect to the corporate network.
- D. Incorrect.
Simple Network Management Protocol (SNMP) is used for monitoring and managing network devices but does not contribute directly to secure access technologies.
- E. Incorrect.
Single Sign-On (SSO) simplifies user authentication across multiple systems but does not ensure secure device or network access by itself.
