You have your laptop directly connected into a router's Ethernet port. Which of the following are among the requirements for the copy flash tftp command to be successful?
  1. TFTP server software must be running on the router.
  2. TFTP server software must be running on your laptop.

Your Answer: Option
(Not Answered)
Correct Answer: Option
Explanation:
Before you back up an IOS image to a laptop directly connected to a router's Ethernet port, make sure the TFTP server software is running on your laptop, that the Ethernet cable is a "crossover," and that the laptop is in the same subnet as the router's Ethernet port, and then you can use the copy flash tftp command from your laptop.

None of the above
Your Answer: Option
(Not Answered)
Correct Answer: Option
Explanation:
The distance-vector routing protocol sends its complete routing table out all active interfaces at periodic time intervals. Link-state routing protocols send updates containing the state of its own links to all routers in the internetwork.

You type debug ip rip on your router console and see that 172.16.10.0 is being advertised to you with a metric of 16. What does this mean?
The route is 16 hops away.
The route has a delay of 16 microseconds.
The route is inaccessible.
The route is queued at 16 messages a second.
Your Answer: Option
(Not Answered)
Correct Answer: Option
Explanation:
You cannot have 16 hops on a RIP network by default. If you receive a route advertised with a metric of 16, this means it is inaccessible.

If your routing table has a static, a RIP, and an IGRP route to the same network, which route will be used to route packets by default?
Any available route
RIP route
Static route
IGRP route
They will all load-balance.
Your Answer: Option
(Not Answered)
Correct Answer: Option
Explanation:
Static routes have an administrative distance of 1 by default. Unless you change this, a static route will always be used over any other found route. IGRP has an administrative distance of 100, and RIP has an administrative distance of 120, by default.

Your company is running IGRP using an AS of 10. You want to configure EIGRP on the network but want to migrate slowly to EIGRP and don't want to configure redistribution. What command would allow you to migrate over time to EIGRP without configuring redistribution?
router eigrp 11
router eigrp 10
router eigrp 10 redistribute igrp
router igrp combine eigrp 10
Your Answer: Option
(Not Answered)
Correct Answer: Option
Explanation:
If you enable EIGRP on a router with the same autonomous system (AS) number, EIGRP will automatically redistribute IGRP into EIGRP. You will see the IGRP injected routes as external (EX) routes with an EIGRP AD of 170. This is a nice feature that lets you migrate slowly to EIGRP with no extra configuration.

Where are EIGRP successor routes stored?
In the routing table only
In the neighbor table only
In the topology table only
In the routing table and the topology table
In the routing table and the neighbor table
Your Answer: Option
(Not Answered)
Correct Answer: Option
Explanation:
Successor routes are going to be in the routing table since they are the best path to a remote network. However, the topology table has a link to each and every network, so the best answer is topology table and routing table. Any secondary route to a remote network is considered a feasible successor, and those routes are only found in the topology table and used as backup routes in case of primary route failure.

Which command will display all the EIGRP feasible successor routes known to a router?
show ip routes *
show ip eigrp summary
show ip eigrp topology
show ip eigrp adjacencies
Your Answer: Option
(Not Answered)
Correct Answer: Option
Explanation:
Any secondary route to a remote network is considered a feasible successor, and those routes are only found in the topology table and used as backup routes in case of primary route failure. You can see the topology table with the show ip eigrp topology command.

You get a call from a network administrator who tells you that he typed the following into his router: 
Router(config)#router ospf 1
Router(config-router)#network 10.0.0.0 255.0.0.0 area 0
He tells you he still can't see any routes in the routing table. What configuration error did the administrator make?
The wildcard mask is incorrect.
The OSPF area is wrong.
The OSPF Process ID is incorrect.
The AS configuration is wrong.
Your Answer: Option
(Not Answered)
Correct Answer: Option
Explanation:
The administrator typed in the wrong wildcard mask configuration. The wildcard should have been 0.0.0.255.

Which of the following protocols support VLSM, summarization, and discontiguous networking?
  1. RIPv1
  2. IGRP
  3. EIGRP
  4. OSPF
  5. BGP
  6. RIPv2
1 and 4
2 and 5
3, 4 and 6
All of the above
Your Answer: Option
(Not Answered)
Correct Answer: Option
Explanation:
RIPv1 and IGRP are true distance-vector routing protocols and can't do much, really-except build and maintain routing tables and use a lot of bandwidth! RIPv2, EIGRP, and OSPF build and maintain routing tables, but they also provide classless routing, which allows for VLSM, summarization, and discontiguous networking.

What is the administrative distance of OSPF?
90
100
110
120
Your Answer: Option
(Not Answered)
Correct Answer: Option
Explanation:
The administrative distance (AD) is a very important parameter in a routing protocol. The lower the AD, the more trusted the route. If you have IGRP and OSPF running, by default IGRP routes would be placed in the routing table because IGRP has a lower AD of 100. OSPF has an AD of 110. RIPv1 and RIPv2 both have an AD of 120, and EIGRP is the lowest, at 90.

When a new trunk link is configured on an IOS-based switch, which VLANs are allowed over the link?
By default, all VLANs are allowed on the trunk.
No VLAN's are allowed, you must configure each VLAN by hand.
Only configured VLAN's are allowed on the link.
Only extended VLAN's are allowed by default.
Your Answer: Option
(Not Answered)
Correct Answer: Option
Explanation:
By default, all VLANs are allowed on the trunk link and you must remove by hand each VLAN that you don't want traversing the trunked link.

Which command will configure a switch port to use the IEEE standard method of inserting VLAN membership information into Ethernet frames?
Switch(config)# switchport trunk encapsulation isl
Switch(config)# switchport trunk encapsulation ietf
Switch(config)# switchport trunk encapsulation dot1q
Switch(config-if)# switchport trunk encapsulation isl
Switch(config-if)# switchport trunk encapsulation dot1q
Your Answer: Option
(Not Answered)
Correct Answer: Option
Explanation:
If you are on a 2950 switch, then the interface command is just switchport mode trunk, since the 2950 can only run the IEEE 802.1Q version. However, a 3550 can run both ISL and 802.1Q, so you must use the encapsulation command. The argument to choose 802.1Q for a trunking protocol is dot1q.
