Chapter C, Problem 1MC

Program Description Answer

 CARP would allow the user to assign the same IP address to all three redundant firewalls.

Hence, the correct answer is option “B”.

Explanation of Solution

 CARP protocol:

• CARP stands for Common Address Redundancy Protocol. It is a computer network protocol that allows several hosts on the same LAN to share a set of IP addresses.
• The main purpose of CARP is to give failover redundancy, particularly used with routers and firewalls.
• It provides the same functionality of virtual router redundancy protocol (VRRP) to Cisco Systems HSRP.

 Explanation for the incorrect options:

SMTP

• The most common protocol used for transferring electronic mail is SMTP.
• Simple mail transfer protocol (SMTP) is used for exchanging the electronic mail and provides a rule between the servers.

Hence, option “A” is wrong.

SNMPv3

 SNMPv3 stands for Simple Network Management Protocol version 3. It does not allow the user to assign the same IP address to all three redundant firewalls.

Hence, option “C” is wrong.

IMAP

 IMAP stands for Internet Message Access Protocol. It is used to access an email on a remote server from a local client. Hence, it does not allow the user to assign the same IP address to all three redundant firewalls.

Hence, option “D” is wrong.

NTP

 NTP stands for Network Time Protocol. It does not allow the user to assign the same IP address to all three redundant firewalls.

Hence, option “E” is wrong.
