Ccna certification Practice Tests

 189.  B.  The default hello interval is 10 seconds for a broadcast (multi-access) network such as a 

LAN. All other answers are incorrect.

 190.  B.  The command 

passive-interface gigabitethernet 0/1 must be configured under 

the router process. This command will suppress hello packets from exiting the Gi0/1 

interface. The command 

passive-interface is incorrect when it is configured inside  

an interface. The command 

passive-interface gigabitethernet 0/1 is incorrect 

when it is configured in global configuration mode. The command 

passive-interface 

default is incorrect.

 191.  C.  The command 

show ip ospf interface will show all interfaces in which OSPF is 

configured and sending hello packets. The command 

show interfaces is incorrect as it 

will only show the interface on the router. The command 

show ip routes is incorrect 

as it will show the route table. The command 

show ip ospf brief is an incorrect 

command.

 192.  D.  Although all of these are valid methods of possibly setting the router ID (RID) of the 

router for OSPF, the configuration of 

router-id 192.168.1.5 will override all others. 

Entering 

interface fa 0/1 and then ip address 192.168.1.5 255.255.255.0 will 

configure an IP address on an interface. Entering 

interface loopback 0 and then ip 

address 192.168.1.5 255.255.255.0 will configure an IP address on the loopback 

interface 0. The command 

rid 192.168.1.5 is incorrect.

 193.  C.  The command 

passive-interface default configured under the OSPF process will 

cease hello packets by default on all interfaces. The command 

no passive-interface 

gigabitethernet 0/2 will allow hello packets to exit the interface and allow Gi0/2 to 

become a neighbor. The command 

active-interface gigabitethernet 0/2 is an 

incorrect command. Therefore, any combination of 

active-interface is incorrect. If 

passive-interface gigabitethernet 0/2 is configured, then gigabitethernet 0/2 will 

not send hello packets.

 194.  A.  After the OSPF configuration is changed, OSPF needs to be restarted. This is achieved 

at the privileged exec prompt by typing 

clear ip ospf. The router configuration prompt 

will not allow 

shutdown and no shutdown commands. The command clear ip ospf is 

incorrect. The command 

clear ospf is incorrect.
