Question 1

An administrator needs to choose a VPN protocol for a site-to-site connection. What factors should the administrator consider when evaluating VPN protocols?

Correct Answer: Security, interoperability, and performance

Security, interoperability, and performance are the key factors to consider when evaluating VPN protocols. Vendor, brand reputation, geographical location, or VPN mode are not specifically important factors in selecting a VPN protocol for a site-to-site connection.

Question 2

A network technician suggests implementing split-tunneling for a VPN connection. What is the primary concern when implementing split-tunneling?

Correct Answer: Increased security risk

Split-tunneling increases the security risk because it allows direct access to the internet, bypassing the organization's security measures. Other concerns such as setup complexity, congestion, latency, access limitations, or compliance violations are not directly related to implementing split-tunneling.

Question 3

Which factor can significantly impact the performance of a VPN?

Correct Answer: Encryption strength

Encryption strength is a major factor impacting VPN performance. Higher encryption levels require more processing power, which can slow down the connection. Other factors like VPN endpoint location, the number of clients, authentication methods, the type of VPN or QoS settings may impact performance, but encryption strength has a more direct impact.
