• Secure Hypertext Transfer Protocol (S-HTTP)

• S/MIME (Secure/Multipurpose internet Mail Extensions)

Which TCP/IP protocol is a secure form of HTTP that uses SSL as a sub-layer for security?

• Simple Mail Transfer Protocol

  (SMTP)

Which of the following tools allow remote management of servers? (Select two.)

• Telnet

SFTP uses which mechanism to provide security for authentication and data transfer?

• Secure Shell Protocol (SSH)

• Secure Shell (SSH)

• Internet Protocol Security (IPsec)

• Token devices

When using SSL authentication, what does the client verify first when checking a server's identity?

• The current date and time must fall within the server's certificate-validity period.

• Master secrets are verifiable from asymmetric keys.

• The certificate must be non-expiring and self-signed by the sysadmin.

• All DNS resolution must point to the corporate intranet routers.

• Authentication Header (AH)

• Layer 2 Tunneling Protocol

  (L2TP)

What is the primary function of the IKE Protocol used with IPsec?
