Troubleshooting and Maintaining Cisco IP Networks (TSHOOT, legacy) — Question 24

Which two features are supported with GRE-based tunnels? (Choose two.)

Answer options

• A. any-to-any connectivity
• B. encryption
• C. multicast traffic forwarding
• D. on-demand runnels
• E. data encapsulation

Correct answer: C, E

Explanation

The correct answers are C and E because GRE tunnels can forward multicast traffic and encapsulate data. Options A and B are incorrect as GRE does not inherently provide any-to-any connectivity or encryption features; those would require additional protocols or configurations.
