Jane, a VPN administrator, was asked to implement an encryption cipher with a MINIMUM effective security of
128-bits. Which of the following should Jane select for the tunnel encryption?

A.
Blowfish

B.
DES

C.
SHA256

D.
HMAC

Explanation:
HMAC (Hash-Based Message Authentication Code) uses a hashing algorithm along with a symmetric key.
HMAC with 128 bit would provide more additional security compared to Blowfish 128 bit as HMAC uses a
symmetric key as well.
