Q 
Which of the following technologies implement authentication headers and encapsulating security payloads?
A. IPSec
B. ISAKMP
C. TLS
D. SSL VPN
A

A. IPSec: The IP Security (IPSec) protocol is designed to provide secure communications
between systems. This includes system-to-system communication in the
same network, as well as communication to systems on external networks.
IPSec is an IP layer security protocol that can both encrypt and authenticate
network transmissions. In a nutshell, IPSec is composed of two separate protocols:
Authentication Header (AH) and Encapsulating Security Payload
(ESP). AH provides the authentication and integrity checking for data packets,
and ESP provides encryption services.

78
Q 
Jeff, a network administrator, needs to forward HTTP traffic from a firewall public IP to the internal web server's private. IP Which of the following can Jeff implement?
A. DNS
B. NAT
C. PKI
D. RAS
A

B. NAT: The basic principle of NAT is that many computers can “hide” behind a single
IP address. The main reason you need to do this (as pointed out earlier in the section “IP Addressing”) is because there simply aren’t enough IPv4 addresses to go around. Using NAT means that only one registered IP address is needed on the system’s external interface, acting as the gateway between the internal and external networks.

79
Q 
Which of the following implements two-factors authentication?
A. Username and password
B. Fingerprint and facial recognition
C. Check card and PIN
D. PIN and password
A

C. Check card and PIN: When two or more access methods are included as part of the authentication
process, you’re implementing a multifactor system. A system that uses any two
items—such as smart cards and passwords—is referred to as a two-factor
authentication system.

the query originates with an IP address.
