- Question
We want to assign port 3 of our Catalyst 2950 switch to VLAN 3. What command will achieve this?
Options- A. switch(config-if)#switchport vlan 3
- B. switch#switchport access vlan 3
- C. switch(config)#switchport access vlan 3
- D. switch(config-if)#switchport access vlan 3
- Correct Answer
- switch(config-if)#switchport access vlan 3
ExplanationExplanation: 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

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: 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: 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: 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: OSPF intra-area and interarea routes, and a default route External routes are not advertised into a stub area
Correct Answer: banner motd
Explanation:
Explanation: This MOTD banner is displayed to all terminals connected and is useful for sending messages that affect all users (such as impending system shutdowns). Use the no exec-banner or no motd-banner command to disable the MOTD banner on a line. The no exec-banner command also disables the EXEC banner on the line. When a user connects to the router, the MOTD banner appears before the login prompt. After the user logs in to the router, the EXEC banner or incoming banner will be displayed, depending on the type of connection. For a reverse Telnet login, the incoming banner will be displayed. For all other connections, the router will display the EXEC banner. Connection, Menu, and System Banner Commands
