Refer to the exhibit. A network administrator has configured OSPFv2 on the two Cisco routers as shown. PC1 is unable to communicate with PC2. What should be done to fix the problem? Add the network 192.168.255.0 0.0.0.3 area 0 command to router R1 and remove the network 192.168.255.1 0.0.0.0 area 0 command. Add the network 192.168.255.2 0.0.0.0 area 0 command to router R1 and remove the network 192.168.255.1 0.0.0.0 area 0command. Add the network 192.168.10.0 0.0.0.255 area 0 command to router R1 and remove the network 192.168.10.1 0.0.0.0 area 0command. Add the passive-interface S0/0 command to router R1. .
When the show spanning-tree vlan 33 command is issued on a switch, three ports are shown in the forwarding state. In which two port roles could these interfaces function while in the forwarding state? (Choose two.) blockedalternate disabled Designated Root.
Which two parameters must match on the ports of two switches to create a PAgP EtherChannel between the switches? (Choose two.) MAC addressVLAN information* port ID Speed PAgP mode .
What is the final operational state that will form between an OSPF DR and a DROTHER once the routers reach convergence? established loading two-way Full.
Which command is used to display the bandwidth of an interface on an EIGRP-enabled router? show ip interface brief show ip protocols show interfaces show ip route .
How are externally learned EIGRP routes identified in the routing table? EX O1 E D *.
What does the SPF algorithm consider to be the best path to a network? The path that includes the fastest single bandwidth link. The path with the smallest delays. The path that includes the fastest cumulative bandwidth links. The path with the least number of hops. .
Which protocol does EIGRP use for the transportation of EIGRP packets? Transmission Control Protocol User Datagram Protocol Real-Time Transport Protocol Reliable Transport Protocol .
What is a function of OSPF hello packets? to ensure database synchronization between routers to discover neighbors and build adjacencies between them to send specifically requested link-state records to request specific link-state records from neighbor routers .
Which routing table descriptor is used to identify the OSPF networks advertised by type 1 LSAs? O O IA O E2 O E1 .
What does an OSPF area contain? routers whose SPF trees are id entical routers that share the same process ID routers that have the same link-state information in their LSDBs routers that share the same router ID .
What two values must match between two EIGRP directly connected neighbors to establish and maintain an adjacency? (Choose two.) autonomous system number metric parameters hello timers router ID Area ID .
Refer to the exhibit. Switch SW-A is to be used as a temporary replacement for another switch in the VTP Student domain. What two pieces of information are indicated from the exhibited output? (Choose two.) The other switches in the domain can be running either VTP version 1 or 2. VLAN configuration changes made on this switch will be sent to other devices in the VTP domain. VTP will block frame forwarding on at least one redundant trunk port that is configured on this switch. This switch will update its VLAN configuration when VLAN changes are made on a VTP server in the same domain. There is a risk that the switch may cause incorrect VLAN information to be sent through the domain. .
What are two reasons to install a single 48-port fixed configuration switch, rather than two 24-port fixed configuration switches, in a wiring closet that supports two classrooms? (Choose two.) more ports available for end devices* more power provided to each port higher uplink speeds reduced power and space requirements.
What is a characteristic of spanning tree? It prevents propagation of Layer 2 broadcast frames. It is enabled by default on Cisco switches. It is used to discover information about an adjacent Cisco device. It has a TTL mechanism that works at Layer 2. .
Refer to the exhibit. A network administrator would like to implement dynamic routing within a small network environment as shown in the exhibit. Which routing protocol would be a viable solution? BGP IGRP RIPv1 EIGRP .
Refer to the exhibit. R1 and R2 are OSPFv3 neighbors. Which address would R1 use as the next hop for packets that are destined for the Internet? 2001:DB8:C5C0:1::2 FF02::5 2001:DB8:ACAD:1::2 FE80::21E:BEFF:FEF4:5538 .
Refer to the exhibit. What will Router1 do if it receives packets that are destined to network 2001:db8:11:100::/64? send the packets out interface Serial 0/0/0 drop the packets send the packets out interface GigabitEthernet 0/0 forward the packets to the gateway of last resort .
Match the order of precedence to the process logic that an OSPFv3 network router goes through in choosing a router ID. (Not all options are used.) priority 1 priority 2 priority 3 priority 4 .
