CompTIA N+

Identify the networking technology.

1. When an external entity accesses an internal network resource, the external IP address is mapped to a fixed IP address

2.When an internal node accesses an external resources, it’s device maps a private IP address to the first IP address that is available from a pool of globally unique IP addresses

Which of the following statement correctly describes disk driver categories of Netware Loadable Modules (NLMs)?

• Disk drivers has a. DKS extension

• Disk drivers communicate with storage devices

• Disk drivers communicate with network interface cards

• Disk drivers enable Netware to store non- DOS file names

Consider the following statement:

Statement A: Remote Access Protocol is a type of protocol that enables user to log on to a computer or network within an organization from an external location.

Statement B: Slip is a legacy remote access protocol use for sending IP byte streams over serial lines such as modem/phone connections.  

Which of the following option is correct with respect to the above statements?

Consider the following statement:

Statement A: in INC notation, file names or other resources names being with single backslash character (\).

Statement B: switched Ethernet is a LAN technology that connects host computer and network segments by using Switches. 

Which of the following option is correct with respect to the above statements? 

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

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

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

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.

4). Set up a RADIUS server. Identify the correct sequence of steps for performing the same activity? 

The network administrator of Green Valley, Tom Baker, needs to set up a network for 10 computers for its newly introduced department. The network needs to be set up based on token-ring architecture between computers. Determine the LAN standard that will meets this requirement.

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
