B. 127.0.0.1
C. 172.16.1.1
D. 192.168.1.1

Answer: B

The loopback interface has no hardware associated with it, and it is not physically connected to a network. The loopback address causes any messages sent to it to be returned to the sending system. The loopback address allows client software to communicate with server software on the same computer. Users specify the loopback address which willpoint back to the computer’s TCP/IP network configuration.
In IPv4, the loopback address is 127.0.0.1.
In IPv6, the loopback address is 0:0:0:0:0:0:0:1, more commonly notated as follows. ::1

Question: 23

Which of the following network devices use ACLs to prevent unauthorized access into company systems?

A. IDS
B. Firewall
C. Content filter
D. Load balancer

Answer: B

Explanation:
A firewall is a system designed to prevent unauthorized access to or from a private network. Firewalls arefrequently used to prevent unauthorized Internet users from accessing privatenetworks connected to the Internet, especially intranets. Firewalls use ACLs (access control lists) to determine which traffic is allowed through the firewall. All traffic entering or leaving the intranet passes through the firewall, which examines each message and blocks or allows the message depending on rules specified in the ACL. The rules in the ACL specify which combinations of source IP address, destination address in IP port numbers are allowed.

Question: 24

Which of the following is used to define how much bandwidth can be used by various protocols on the network?

A. Traffic shaping
B. High availability
C. Load balancing
D. Fault tolerance

Answer: A

Explanation:
If a network connection becomes saturated to the point where there is a significant level of contention, network latency can rise substantially.
Traffic shaping is used to control the bandwidth used by network traffic. In a corporate environment, business-related traffic may be given priority over other traffic. Traffic can be prioritized based on the ports used by the application sending the traffic. Delayed traffic is stored in a buffer until the higher priority traffic has been sent.

Question: 25

A. OSPF
B. VTP trunking
C. Virtual PBX
D. RADIUS
E. 802.1x

Answer: D,E

Explanation:
D: A RADIUS (Remote Authentication Dial-in User Service)server is a server with a database of user accounts and passwords used as a central authentication database for users requiring network access. RADIUS servers are commonly used by ISP’s to authenticate their customer’s Internet connections.
Remote users connect to one or more Remote Access Servers. The remote access servers then forward the authentication requests to the central RADIUS server.
E: 802.1X is an IEEE Standard for Port-based Network Access Control (PNAC). It provides an authentication mechanism to devices wishing to attach to a network.
802.1X authentication involves three parties: a supplicant, an authenticator, and an authentication server. The supplicant is a client that wishes to attach to the network. The authenticator is a network device,such as an Ethernet switch, wireless access point or in this case, a remote access server and the authentication server is the RADIUS server.

Question: 26
