Ssl inbound inspection requires that the firewall be configured with which two components? (choose two.)

I believe that the Multiple answers attached to this question is 

a) Client's digital certificate
b) Client's public key
c) Server's digital certificate
d) Server's private key

The answer should be A and B
Digital certificates are used to ensure that there is trust between secure connections. Firewalls must also use a public key which is contained in the root CA certificate.
