1. In what two ways does SDM differ from the IOS CLI? (Choose two.)
**SDM is used for in-band management only. The IOS CLI can be used for in-band and out-of-band management.
SDM is accessed through a Telnet application. The IOS CLI is accessed through a web browser.
SDM is available for all router platforms. The IOS CLI is available for a limited number of Cisco devices.
**SDM utilizes GUI buttons and text boxes. The IOS CLI requires the use of text-based commands.
SDM is used for advanced configuration tasks. The IOS CLI is preferred for initial basic device configuration.

2. Which mode will a configured router display at login?
global configuration mode
setup mode
ROM monitor mode
**user EXEC mode

1. Refer to the exhibit. Which command will advertise the 192.168.1.64/30 network but not the 192.168.1.32 network on router A?
network 192.168.1.64 0.0.0.3

2. Refer to the exhibit. EIGRP is the only routing protocol enabled on this network. No static routes are configured on this router. What can be concluded about network 198.18.1.0/24 from the exhibited output?
Packets that are destined for 198.18.1.0/24 will be forwarded to 198.18.10.6.

3. On a router running EIGRP, what database would maintain a list of feasible successors?
topology table

1. Refer to the exhibit. What protocol was used to distribute the routing information for the network 172.16.1.4?
RIPv2

2. Refer to the exhibit. A packet destined for host 128.107.0.5/16 is processed by the JAX router. After finding the static route in the routing table that matches the destination network for this packet, what does the router do next?
performs a recursive lookup to find the exit interface used to forward the packet

3. Refer to the exhibit. What parent network will automatically be included in the routing table when the three subnets are configured on Router1?
172.16.0.0/16

1. Refer to the exhibit. When Router D is configured to use a link-state routing protocol and is added to the network, what is the first thing that it does to begin learning the network topology?
It learns about its directly connected networks when its interfaces reach the up state.

2. What two events will cause a link state router to send LSPs to all neighbors? (Choose two.)
whenever the network topology changes
upon initial startup of router or routing protocol

3. What is the final step in the link state routing process?
SPF computes best path to each destination network

1. Refer to the exhibit. What configuration statements would give the results that are shown in the output of the show ip protocols command?
B(config)# router ospf 1
B(config-router)# router-id 192.168.1.5

2. Refer to the exhibit. All routers have been configured with the interface priorities that are shown. All routers were restarted simultaneously. The results of the DR/BDR election are shown. What can be concluded about this network?
The highest router ID was most likely determined via an OSPF router-id statement or statements.

3. Refer to the exhibit. When OSPF is operational in the exhibited network, what neighbor relationship is developed between Router1 and Router2?
A FULL adjacency is formed.

Refer to the exhibit. What two statements are true based on the output shown? (Choose two.)
- neighbors 192.168.10.9 and 192.168.10.5 have auto summary disabled
- router 3 is load balancing traffic to the 172.16.3.0 network across its serial interfaces

Refer to the exhibit. The network administrator issues the command no ip classless on Router1. What forwarding action will take place on a packet that is received by Router1 and is destined for host 192.168.0.26?
- The packet will be dropped.

1. Refer to the exhibit. The network administrator issues the command no ip classless on Router1. What forwarding action will take place on a packet that is received by Router1 and is destined for host 192.168.0.26?
• The packet will be dropped
• The packet will be forwarded to the gateway of last resort.
• The packet will match the 192.168.0.0 network and be forwarded out Serial 0/0.
• The packet will most closely match the 192.168.0.8 subnet and be forwarded out Serial 0/1.

2. Which three statements are true of holddown timers? (Choose three.)
• used by link state routing protocols to prevent routing loops
• prevent update messages from reinstating a route that may have gone bad
• allow routers to still forward packets to destination networks that are in holddown
• limit the number of hops a packet can traverse through the network before it is discarded
• prevent a router advertising a network through the same interface from which the network was learned
• permit lower metric updates received from any neighboring router to reinstate the route to a possibly down Network

** from R3 to 192.168.1.1
172.16.4.0/24

2. A router that uses the RIP routing protocol has an entry for a network in the routing table. It then receives an update with another entry for the same destination network but with a lower hop count. What action will the router take for this new update?
** It will append the update information to the routing table.
It will invalidate the entry for that network in the routing table.
It will replace the existing routing table entry with the new information.
It will ignore the new update.
