Question 143

The following description of the CHAP authentication function in the PPP protocol is correct?( Multiple choice questions).

The user name must be configured under the authenticated party interface for CHAP authentication

If the authenticator does not have a username configured, password

can also be configured without the authenticated party interface Using the authentication sequence ID, random number, and key, a Hash value

is calculated using the MD5 algorithm Three message interactions are required for authentication, and only the user name is transmitted on the network without the password

Question 147

The following is an error in the OSPF routing calculation (single choice).

Compared to the PRC algorithm, the ISPF algorithm only calculates the changed leaf nodes when the route changes PRC algorithm to recalculate routes

When the first and second class LSAs on the network change, OSPF uses the ISPF algorithm to recalculate the routes The

OSPF router uses the FULL SPF algorithm to calculate all nodes in the network when initially calculating routes
