More CCNA questions

Some Very Important CCNA questions for the interview.

Cisco Career Certifications are IT professional certifications for Cisco products. The tests are administered by Pearson VUE (Prometric previously administered the test; but as of 1 Aug 2007, no longer does). There are three levels of certification: Associate, Professional, and Expert.
To Prepare to these Test Follow the Below Cisco TEST Questions

1. You need to retrieve a file from the file server for your word processing application, which layer of the OSI model is responsible for this function?
   1. Presentation layer
   2. Application layer
   3. Session layer
   4. Transport layer
   5. Datalink layer
2. You are working in a word processing program, which is run from the file server. Your data comes back to you in an unintelligible manner. Which layer of the OSI model would you investigate?
   1. Application layer
   2. Presentation layer
   3. Session layer
   4. Network layer
   5. Datalink layer
3. The IEEE subdivided the datalink layer to provide for environments that need connectionless or connection-oriented services. What are the two layers called?
   1. Physical
   2. MAC
   3. LLC
   4. Session
   5. IP
4. You are working with graphic translations. Which layer of the OSI model is responsible for code formatting and conversion and graphic standards.
   1. Network layer
   2. Session layer
   3. Transport layer
   4. Presentation layer
5. Which is the best definition of encapsulation?
   1. Each layer of the OSI model uses encryption to put the PDU from the upper layer into its data field. It adds header and trailer information that is available to its counterpart on the system that will receive it.
   2. Data always needs to be tunneled to its destination so encapsulation must be used.
   3. Each layer of the OSI model uses compression to put the PDU from the upper layer into its data field. It adds header and trailer information that is available to its counterpart on the system that will receive it.
   4. Each layer of the OSI model uses encapsulation to put the PDU from the upper layer into its data field. It adds header and trailer information that is available to its counterpart on the system that will receive it.
6. Routers can be configured using several sources. Select which of the following sources can be used.

11. What does the command “IP name-server 255.255.255.255? accomplish?
