11. Jack Pen is a network administrator at Blue Soft inc. his organisation has open a new branch that needs to be connected to other branch over WAN. Jack needs to suggest a WAN standard keeping certain fctor in mind. The connection medium is fiber optices. The standard so implemented should suppord for data transfer speeds up to 2.48 Gbps. It should also be able to recover from network faults without much intervention. Which of the following WAN standared would best fulfill Jack’s requirement?

Integrted service digital network

Asynchronous transfer mode

Synchronous digital hierarchy

Synchronous optical network

12. Which of the following statement is TRUE for coaxial cables?

It uses light rays instead of electricity to transmit data

It can be differentiated into the two categories, single-mode and multimode

It use copper wires, which are good conductors of electricity

Coaxial cables provide effective protection against electromagnetic interference during data transmission

13. Kevin, network administrator of GlobalShopping Inc. has implemented a security feature to carry out secure transmissions on the company’s web site. The security feature involves a heirarchical system of Certification Authority, certificates, service and other cryptographic components. This helps in authenticating and validating data and entities. The system issues and maintains public/ private key pairs and certificates for carrying out the authentication process. What type of security architecture has been implemented in this scenario?

Kerberos

Digital certificate

PKI

Extensible Authentication Protocol

14. To implement a Remort Access Solution, John a network administrator planes to implement RADIUS for remort authentication. Identify the correct sequence of the following logical steps, to implement the same:

1). Idendify the authentication methods supported by RRAS.

2). Reconfigure your RRAS server to use RADIUS authentication.

3). Install the internet Authentication Service.

16. You’re working at the help desk and you get a call that a user can’t access the UNIX host at 150.150.32.157. You are on the same subnet as the user and the UNIX host and you can successfully ping both the UNIX host and the user’s workstation. When you ask the user to enter ping 150.15032.157, all he gets is a series of Destination unreachable massage. What could be the possible cause of error?

Duplicate IP address in the network

Problem with router configuration table

On the server there is a bad MAC address entry in the cache

On the user’s workstation there is a bad MAC address entry in the cache
