CCNA 3 Chapter 8 Exam Answers Which three addresses could be used as the destination address for OSPFv3 messages? (Choose three.) FF02::A FF02::1:2 2001:db8:cafe::1 FE80::1* FF02::6* FF02::5* Fill in the blank. OSPF uses _______ as a metric. Correct Answer: cost* What are the two purposes of an OSPF router ID? (Choose two.) to enable the SPF algorithm to determine the lowest cost path to remote networks to facilitate the establishment of network convergence to uniquely identify the router within the OSPF domain* to facilitate router participation in the election of the designated router* to facilitate the transition of the OSPF…

CCNA 3 Chapter 7 Exam Answers Refer to the exhibit. After the configuration shown is applied on router R1, the exhibited status message is displayed. Router R1 is unable to form a neighbor relationship with R2 on the serial 0/1/0 interface. What is the most likely cause of this problem? The network statement used for EIGRP 55 does not enable EIGRP on interface serial 0/1/0. The hello interval has been altered on serial 0/1/0 and is preventing a neighbor relationship from forming. The IPv4 address configured on the neighbor that is connected to R1 serial 0/1/0 is incorrect.* The networks…
CCNA 3 Chapter 6 Exam Answers What information does EIGRP maintain within the routing table? only successors* all routes known to the router only feasible successors both successors and feasible successors adjacent neighbors Which configuration is necessary to ensure successful operation of EIGRP for IPv6? The eigrp router-id command requires an IPv6 address within the router configuration mode. The network command is required within the router configuration mode. The no shutdown command is required within the router configuration mode.* The router eigrp autonomous-system command is required within the router configuration mode. Fill in the blank. In an EIGRP topology table,…
CCNA 3 Chapter 5 Exam Answers A network administrator is researching routing protocols for implementation in a critical network infrastructure. Which protocol uses the DUAL algorithm to provide almost instantaneous convergence during a route failover? RIP BGP OSPF EIGRP* Which routing protocol sends a routing update to neighboring routers every 30 seconds? RIP* BGP OSPF EIGRP Which statement is an incorrect description of the OSPF protocol? Multiarea OSPF helps reduce the size of the link-state database. When compared with distance vector routing protocols, OSPF utilizes less memory and less CPU processing power.* OSPF builds a topological map of the network.…
CCNA 3 Chapter 4 Exam Answers What is the purpose of HSRP? It provides a continuous network connection when a router fails.* It prevents a rogue switch from becoming the STP root. It prevents malicious hosts from connecting to trunk ports. It enables an access port to immediately transition to the forwarding state. Refer to the exhibit. An EtherChannel was configured between switches S1 and S2, but the interfaces do not form an EtherChannel. What is the problem? The switch ports have to be configured as access ports with each port having a VLAN assigned. The interface port-channel number has…
CCNA 3 Chapter 3 Exam Answers Which two network design features require Spanning Tree Protocol (STP) to ensure correct network operation? (Choose two.) redundant links between Layer 2 switches* link-state dynamic routing that provides redundant routes implementing VLANs to contain broadcasts static default routes removing single points of failure with multiple Layer 2 switches* Which STP priority configuration would ensure that a switch would always be the root switch? spanning-tree vlan 10 root primary spanning-tree vlan 10 priority 0* spanning-tree vlan 10 priority 4096 spanning-tree vlan 10 priority 61440 What additional information is contained in the 12-bit extended system ID…
CCNA 3 Chapter 2 Exam Answers Where is the vlan.dat file stored on a switch? on the externally attached storage media or internal hard drive in RAM in NVRAM in flash memory* How are IP addressing designs affected by VLAN implementations? Each VLAN must have a different network number.* VLANs do not use a broadcast address. VLANs do not support VLSM. Each VLAN must have a different subnet mask. What is a disadvantage of using multilayer switches for inter-VLAN routing? Multilayer switches have higher latency for Layer 3 routing. Spanning tree must be disabled in order to implement routing on…
CCNA 3 Chapter 1 Exam Answers What network design would contain the scope of disruptions on a network should a failure occur? the reduction in the number of redundant devices and connections in the network core the configuration of all access layer devices to share a single gateway the installation of only enterprise class equipment throughout the network the deployment of distribution layer switches in pairs and the division of access layer switch connections between them * What are three access layer switch features that are considered when designing a network? (Choose three.) speed of convergence failover capability broadcast traffic…
CCNA 3 Pretest Exam Answers What route would have the lowest administrative distance? a directly connected network* a route received through the EIGRP routing protocol a static route a route received through the OSPF routing protocol Refer to the exhibit. How is a frame sent from PCA forwarded to PCC if the MAC address table on switch SW1 is empty? SW1 floods the frame on all ports on the switch, excluding the interconnected port to switch SW2 and the port through which the frame entered the switch. SW1 forwards the frame directly to SW2. SW2 floods the frame to all…
CCNA 1 Final Exam Answers 1 A medium-sized business is researching available options for connecting to the Internet. The company is looking for a high speed option with dedicated, symmetric access. Which connection type should the company choose? DSL dialup satellite leased line* cable modem 2 What is the purpose of having a converged network? to provide high speed connectivity to all end devices to make sure that all types of data packets will be treated equally to achieve fault tolerance and high availability of data network infrastructure devices to reduce the cost of deploying and maintaining the communication infrastructure*…
