11

What is the purpose of Positive Acknowledgment and Retransmission (PAR)?

PAR allows the presentation layer to request that data be resent in a format the

destination host can process.

PAR provides a mechanism for the receiving device to request that all segments b

e retransmitted if one segment is corrupt.

*PAR helps ensure that a number of data segments sent by one host are received b

y another host before additional data segments are sent.

PAR is used to renegotiate the window size during the synchronization process.

*first two bits of binary IP address are 10

first three bits of IP binary address are 110



13

An administrator has made routing protocol changes to a router's configuration.

To ensure that the changes are implemented, the active configuration is saved an

d the router is reloaded. After the router has initialized, the output on the sc

reen displays "Would you like to enter the initial configuration dialog?[yes/no]

:" Why did this dialog appear?

There was a POST failure.

The incorrect IOS loaded.

There was an error in the startup configuration file.

*The configuration register was set to ignore NVRAM.



14

What operations are performed during router initialization? (Choose three.)

*The IOS is loaded into RAM.

*The generic bootstrap loader tests all interfaces.

All directly connected network devices are identified.

*A valid configuration file is loaded from NVRAM if specified by the configurati

on register.

A question driven setup menu is presented if a valid configuration file cannot b

e loaded.



15

For a network manager planning the installation of a new network, which of the f
