True of false?

MD5 is the only data integrity method applicable to the FWZ scheme.
True of false?

A.
True

B.
False

Explanation:

: This is true, in the case we use the FWZ encryption scheme we can only provide data integrity
through the use of MD5 (Message Digest 5), in case that we use the IKE encryption scheme, we

also have the option to use “SHA-1” (Secure Hashing Algorithm) to provide data integrity in the
VPN´s. So, IKE supports MD5 and SHA-1 and FWZ only supports MD5.
