What types of routes are allowed into a stub area?

Correct Answer: OSPF intra-area and interarea routes, and possibly a default route External routes from ABRs are blocked, and external routes from ASBRs are converted to N1 or N2 routes

Correct Answer: Classless routing protocols advertise subnet mask information along with the network prefixes Classful routing protocols do not Therefore, for a classful protocol, all subnets for the major network number being used must be the same length Also, classful protocol cannot support discontiguous networks prefixes

Correct Answer: Routing moves a letter or telephone call to the access layer (as in a street or telephone exchange) Switching makes the final delivery A switching decision is made on the part of the address that is not used in routing (as in the street number or last four digits of a phone number)

Correct Answer: Using multiple protocols is modular and allows changes to one protocol without affecting the others For example, if the addressing protocol is dependent on the delivery protocol, changes to one would imply changes need to be made to the other

Correct Answer: Answer: FA 16 = 250 10, CE 16 = 206 10, 12 16 = 18 10, and 34 16 = 52 10 FACE1234 16 = 2502061852 dotted decimal

Correct Answer: OSPF databases on routers in the same area must be identical If route summarization was allowed within an area, some routers would have specific routes and some routers would have summary routes for routes in the area If this were allowed, the databases for the area would never agree

Correct Answer: The router with the highest interface priority will be the router ID If all the interface priorities on the multi-access network are the same, the router with the highest router ID will be the DR

Correct Answer: By default, all routes are advertised into all OSPF areas This includes interarea OSPF routes and external routes that have been injected into OSPF By default, IS-IS does not advertise interarea or external routes into an area, but injects a default route

Correct Answer: If a router has more than one route to the same IP prefix, the best path is the one with the shortest AS_PATH (assuming other BGP attributes are equal)

Correct Answer: switch(config-if)#switchport access vlan 3

Explanation:

Explanation: The switchport access vlan [number] command will configure a switch port to that VLAN. You can also use the switchport access vlan dynamic command to configure the switch port automatically in a certain VLAN depending on the VLAN membership of the incoming packets. For both commands to work properly the switch port needs to be in access mode
