A static route is established.
The traffic for all Class C networks is forwarded to 172.16.1.2.
Refer to the exhibit. RIPv1 has been used as a routing protocol on the network. A new 172.16.2.0/24 network has been added on router R2 and configured under the RIP routing process. When will R1 converge?
after 13 seconds
after 30 seconds
after 180 seconds
after R1 receives triggered updates from R2

The enable password should be an enable secret password.
No username and password combination has been configured.
Console connections cannot be configured to require users to provide passwords.
Refer to the exhibit. An administrator is attempting to configure a router by copying and pasting the commands that are shown in the exhibit. However, only one of the FastEthernet interfaces is coming up. What is the problem?
Both interfaces are in the same IP subnet.
FastEthernet0/1 does not have a description.
There can be only one FastEthernet interface enabled on a router at one time.
The administrator did not exit to global configuration mode before configuring FastEthernet0/1.
Refer to the exhibit. The command ip route 0.0.0.0 0.0.0.0 S0/0/0 is run on router R2. What are the two results of this command? (Choose two.)
A static route will be updated in the routing table.
The traffic from the Internet will be directed to R2.
The traffic from the source network 172.16.0.0/22 will be blocked.
The route will be specified as the default route for all networks not defined in the routing table.
All the broadcasts will be forwarded via the S0/0/0 interface of R2.
Refer to the exhibit. All routers are running the same routing protocol. Based on the exhibit and its displayed commands, which statement is true?
The wildcard mask is incorrectly configured.
A default route must be configured on every router.
Routers B, C, and D have no access to the Internet.

Refer to the exhibit. Which combination of network ID and subnet mask can be used to meet the 24 host requirement of the LAN that is attached to Router3?
A network administrator has been asked to configure a network using a classful IP addressing scheme. Which statement is true about the IP addressing that will be used?
Classful IP addresses can be used only when static routing is configured in the network.
Classful IP addresses allow the network/host boundary to occur at any bit in the 32-bit address.
The subnet mask for classful IP addresses can be determined by the value of the first octet of the IP address.
Classful IP addresses require the subnet mask to be included in the routing updates that are propagated by the classful routing protocols.
Which range of IP addresses will be used by RIPv2, EIGRP, and OSPF routing protocols to send routing advertisements?
Refer to the exhibit. Both routers are using the RIPv2 routing protocol and static routes are undefined. R1 can ping 192.168.2.1 and 10.1.1.2, but is unable to ping 192.168.4.1.
What is the reason for the ping failure?
The serial interface between two routers is down.
R2 is not forwarding the routing updates.
The 192.168.4.0 network is not included in the RIP configuration of R2.
RIPv1 needs to be configured.
Refer to the exhibit. When troubleshooting a network, it is important to interpret the output of various router commands. On the basis of the exhibit, which three statements are true? (Choose three.)
The missing information for Blank 1 is the command show ip route.
The missing information for Blank 1 is the command debug ip route.
The missing information for Blank 2 is the number 100.
The missing information for Blank 2 is the number 120.
The missing information for Blank 3 is the letter R.
The missing information for Blank 3 is the letter C.
Refer to the exhibit. The network is using the RIPv2 routing protocol. If network 10.0.0.0 goes down, what mechanism will prevent Router1 from advertising false routing information back to Router2?
Refer to the exhibit. All routers are configured with RIPv2 active on all interfaces. Automatic summarization is in effect. Why does the routing table on R3 include the 18.104.22.168/30 network but not the 172.30.1.0/24 and 172.30.2.0/24 networks?
CIDR is required to route supernets.
There is no default gateway configured.
The 172.30.0.0/16 subnets are discontiguous.
RIPv2 cannot route networks with variable subnets.
Refer to the exhibit. The routers in the exhibit are running the EIGRP routing protocol. What statement is true regarding how packets will travel from the 172.16.1.0/16 network to the 192.168.200.0/24 network?
The router chooses the first path that it learned and installs only that route in the routing table.
The router chooses the path with the lowest administrative distance and installs only that route in the routing table.
The router chooses the highest routing ID based on the advertised network IP addresses and installs only that route in the routing table.
The router installs all the equal cost paths in the routing table but sends packets out only one, holding the others in reserve in case the primary route goes down.
The router installs all the equal cost paths in the routing table and performs equal cost load balancing to send packets out multiple exit interfaces.
Refer to the exhibit. Which two statements are true based on the exhibited output? (Choose two.)
All routes are stable.
Each route has one feasible successor.
The serial interface between the two routers is down.

Add the command no auto-summary on all routers.
Change the network statements to include a wildcard mask.
Adjust the EIGRP hello timers to account for the network delay.
Add the command eigrp log-neighbor-changes on all routers.
Refer to the exhibit. What information can be determined from the displayed output?
EIGRP packets are waiting to be sent to the neighbors.
The adjacencies between the routers are yet to be established.
The IP address 192.168.10.10 is configured at serial interface S0/0/1 of router R2.
Router R2 is receiving hello packets from a neighbor with the IP address 192.168.10.10 via the R2 S0/0/1 interface.
Refer to the exhibit. What will happen if interface Serial0/0/1 goes down on Router1?
The Dijkstra algorithm will calculate the feasible successor.
DUAL will query neighbors for a route to network 192.168.1.0.
Neighbor 172.16.3.2 will be promoted to the feasible successor.
Traffic destined to the 192.168.1.0 network will be dropped immediately due to lack of a feasible successor.
Refer to the exhibit. A network administrator is trying to determine why router JAX has no OSPF routes in its routing table. All routers are configured for OSPF area 0. From the JAX router, the administrator is able to ping its connected interfaces and the Fa0/1 interface of the ORL router but no other router interfaces. What is a logical step that the network administrator should take to troubleshoot the problem?
Reboot the routers.
Change the OSPF process ID on all of the routers to 0.
Check to see if the cable is loose between ORL and JAX.
Check to see if CDP packets are passing between the routers.

They are used for dynamic neighbor discovery. They are used to maintain neighbor relationships.
