Implementing Cisco Network Security (IINS, legacy) — Question 82

Which command enables subnet 192.168.8.4/30 to communicate with subnet 192.168.8.32/27 on IP protocol 50?

Answer options

• A. permit esp 192.168.8.4 255.255.255.252 192.168.8.32 255.255.255.224
• B. permit esp 192.168.8.4 0.0.0.31 192.168.8.32 0.0.0.31
• C. permit esp 192.168.8.4 255.255.255.224 192.168.8.32 255.255.255.192
• D. permit esp 192.168.8.0.0.0.3 192.168.8.32 0.0.0.31

Correct answer: D

Explanation

The correct answer, D, correctly specifies the source and destination addresses along with the appropriate subnet masks to enable communication between the two subnets. Options A, B, and C do not match the required subnet masks for 192.168.8.4/30 and 192.168.8.32/27, making them invalid for this purpose.
