E-mail messages can be easily forged on the Internet. What can you use to be certain that a sender is who he or she claims to be?

 

A. ACL
B. SSL
C. Firewall
D. Certificate

 

Answer:
D. Certificate

 

Tutorial:
Certificates (digital signatures) are primarily used to verify the identity of a sender, but they can also be used to ensure that data, such as documents, arrives at the destination untampered with.

 

An Access Control List (ACL) is a series of conditions that determine if network traffic should be passed on or blocked. Firewalls and routers use ACLs to filter out unwanted traffic.

 

Secure Sockets Layer (SSL) is a protocol used for secure Internet transactions.

 

Firewalls filter unwanted traffic from private networks.

 

These questions are derived from the Self Test Software Practice Test for CompTIA Exam #IK0-002: i-Net+.
