CCNA2 Chapter 2 ( Name ______________________________________

1. What output would you expect from show interface serial 0/0 if the administrator forgot to give the no shutdown command?
• Serial0/0 is up, line protocol is up
• Serial0/0 is down, line protocol is down
• Serial0/0 is up, line protocol is down
• Serial0/0 is administratively down, line protocol is down
•Serial0/0 is down, line protocol is up

2. What output would you expect from show interface serial 0/0 if the serial cable is faulty?
• Serial0/0 is up, line protocol is up
• Serial0/0 is down, line protocol is down
• Serial0/0 is up, line protocol is down
• Serial0/0 is administratively down, line protocol is down
• Serial0/0 is down, line protocol is up

3. Whatoutput would you expect from show interface serial 0/0 if the serial cable has been connected the wrong way round?
• Serial0/0 is up, line protocol is up
• Serial0/0 is down, line protocol is down
• Serial0/0 is up, line protocol is down
• Serial0/0 is administratively down, line protocol is down
• Serial0/0 is down, line protocol is up

4. What output would you expect fromshow interface serial 0/0 if the serial interface on the router at the other end has not been configured?
• Serial0/0 is up, line protocol is up
• Serial0/0 is down, line protocol is down
• Serial0/0 is up, line protocol is down
• Serial0/0 is administratively down, line protocol is down
• Serial0/0 is down, line protocol is up

5. What output would you never expect fromshow interface serial 0/0?
• Serial0/0 is up, line protocol is up
• Serial0/0 is down, line protocol is down
• Serial0/0 is up, line protocol is down
• Serial0/0 is administratively down, line protocol is down
• Serial0/0 is down, line protocol is up

6. When configuring a static route over a point to point link, why is it better to give the exit interface rather thanthe next hop IP address?
• Devices on a point to point link do not have IP addresses.
• The MAC address of the next hop router can be found more quickly.
• There is less processing because the router only needs to check the routing table once.
• There is less processing because the router does not need to check the routing table.

7. When is it better to configure a staticroute by giving a next hop address rather than an exit interface?
• When the next hop is on a multi-access network
• When the next hop is on a WAN link running the PPP protocol
• When the next hop is on a WAN link running the HDLC protocol
• When the next hop is on a serial cable and the router is at the DCE end.

8. What is recursive lookup?
• The router has to checkthrough the routing table more than once in order to find a route to a destination.
• The router makes use of every entry in the routing table before finding a route to a network.
• The router checks the routing table repeatedly but does not find a route to a network.
• The router checks the routing table but does not find the destination network, so it uses the default route.

9. Whattype of route has an administrative distance of 1 by default?
• A default route
• A static route
• A RIP route
• A directly connected route

10. A route in the routing table is marked with *. What kind of route is this?
• A default route
• A static route
• A dynamic route
• A directly connected route

11. What command could you give in order to find themodel of a directly connected Cisco router?
• Show ip route
• Show ip neighbors
• Show cdp neighbors
• Show ip interface detail

12. The RIP routing protocol has found a route to network 192.168.7.0/24 through serial 0/0 but there is also a static route to the same network through serial 0/1. Which route will be preferred and placed in the routing table?
• The RIP...
