18.The enable secret password appears as an MD5 hash in a router's configuration file, whereas
the enable password is not hashed (or encrypted, if the passwordencryption service is not
enabled). What is the reason that Cisco still support the use of both enable secret and enable
passwords in a router's configuration?
A.The enable password is used for IKE Phase I, whereas the enable secret password is used for IKE
Phase II.
B.The enable password is considered to be a router's public key, whereas the enable secret password is
considered to be a router's private key.
C.Because the enable secret password is a hash, it cannot be decrypted. Therefore, the enable password
is used to match the password that was entered, and the enable secret is used to verify that the enable
password has not been modified since the hash was generated.
D.The enable password is present for backward compatibility.
Correct:D
19.On the basis of the description of SSLbased VPN, place the correct descriptions in the proper
locations.
