It’s time for your finals! The Cisco Certified Network Associate programme has led you to this very moment, and it’s finally time to see if you’ve learned enough about routing protocols to secure yourself a noble career in the networking department. Let’s see how well you do! Good luck!
The address assigned to the Ethernet0 interface of Router1 is a broadcast address for that subnetwork.
The subnetwork configured on the serial link between Router1 and Router2 overlaps with the subnetwork assigned to Ethernet0 of Router3.
The subnetwork assigned to the Serial0 interface of Router1 is on a different subnetwork from the address for Serial0 of Router2.
The subnetwork assigned to Ethernet0 of Router2 overlaps with the subnetwork assigned to Ethernet0 of Router3.

Slow convergence
Incorrectly configured static routes
Routes that are learned via two routing protocols
Static and dynamic routing being used on the same router
Lack of a default route on the router that connects to the Internet
It connects multiple IP networks.
It controls the flow of data via the use of Layer 2 addresses.
It determines the best path to send packets.
It manages the VLAN database.
It increases the size of the broadcast domain.
Tests Layer 2 connectivity
Operates a OSI layers 2 and 3
Enabled by default on each interface
Used for debugging Layer 4 connectivity issues
Provides information on directly connected devices that have CDP enabled
The router uses the startup configuration file to start POST.
If the Cisco IOS cannot be found, the router enters setup mode.
The bootstrap program searches for the startup configuration file in NVRAM.
If the startup config file cannot be found, the router enters ROMMON mode.
The router searches for a TFTP server if the startup configuration file is absent at the default location.

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.
Using dynamic routing instead of static routing would have required fewer configuration steps.
The 10.1.1.0/24 and 10.1.2.0/24 routes have adjacent boundaries and should be summarized.
Packets routed to the R2 Fast Ethernet interface require two routing table lookups.
The static route will not work correctly.
If EIGRP is used with default configurations, the data will be equally distributed between two paths — A, D, B and A, C, B.
If RIPv1 is used with default configurations, the data will be load-balanced on all paths.
If EIGRP and OSPF are both used with default configurations, the data will be sent through paths learned by the OSPF protocol.
If RIPv2 is used with default configurations, the data will be equally distributed between two paths — A, D, B and A, C, D.
It will drop the packet.
It will forward the packet to interface Serial0/0/0.
It will determine the route for the packet through a routing protocol.
It will forward the packet to the default gateway.

They are aware of the complete network topology.
They offer rapid convergence times in large networks.
They do not include subnet masks in their routing updates.
They rely on decreasing hop counts to determine the best path.
They pass their entire routing tables to their directly connected neighbors only.
It uses the Bellman-Ford algorithm to determine the best path.
It displays an actual map of the network topology.
It offers rapid convergence in large networks.
It periodically sends complete routing tables to all connected devices.
It is beneficial in complex and hierarchically designed networks.
If the network uses the RIP protocol, router A will determine that all paths have equal cost.
If the network uses the RIP protocol, router A will update only the A-C-E path in its routing table.
If the network uses the EIGRP routing protocol, router A will determine that path A-D-E has the lowest cost.
If both RIP and EIGRP protocols are configured on router A, the router will use the route information that is learned by the RIP routing protocol.
Both routes are installed and load balancing occurs across both paths.
The route via Path B is installed because the EIGRP route has the best metric to network 10.2.0.0/16.
The route via Path A is installed because the static route has the best metric to network 10.2.0.0/16.
The route via Path B is installed because the EIGRP route has the lowest administrative distance to network 10.2.0.0/16.
The route via Path A is installed because the static route has the lowest administrative distance to network 10.2.0.0/16.

Send hello to discover neighbors and form adjacencies

All of the 192.168.x.0 networks will be in the routing table.
Routes to networks 192.168.1.0/24, 192.168.2.0/24, and 192.168.3.0/24 will be in the routing table.
The routing table will be empty because routes and dynamic routes have not been configured.
A default route is automatically installed in the routing table to allow connectivity between the networks.

IP classless has been disabled on the Suffolk router.
The ip subnet-zero command was not configured on the Suffolk router.
