Implementing and Operating Cisco Security Core Technologies (SCOR) — Question 318

What is the function of the crypto isakmp key cisc406143794 address 0.0.0.0 0.0.0.0 command when establishing an IPsec VPN tunnel?

Answer options

• A. It prevents all IP addresses from connecting to the VPN server.
• B. It configures the pre-shared authentication key.
• C. It configures the local address for the VPN server.
• D. It defines what data is going to be encrypted via the VPN.

Correct answer: B

Explanation

The correct answer is B because the command specifies the pre-shared key used for authenticating the VPN connection. Option A is incorrect as the command does not block connections; Option C is misleading since it does not set a specific local address; and Option D is wrong because it does not define what data is encrypted.
