CCNA2_Final_Exam _Q21-Q40

21. Refer to the exhibit. Host A has sent a packet to host B. What will be the source MAC and IP addresses on the packet when it arrives at host B?. Source MAC: 00E0.FE91.7799 Source IP: 10.1.1.10. Source MAC: 00E0.FE10.17A3 Source IP: 10.1.1.10. Source MAC: 00E0.FE10.17A3 Source IP: 192.168.1.1. Source MAC: 00E0.FE91.7799 Source IP: 10.1.1.1. Source MAC: 00E0.FE91.7799 Source IP: 192.168.1.1.

23. Refer to the exhibit. In addition to static routes directing traffic to networks 10.10.0.0/16 and 10.20.0.0/16, Router HQ is also configured with the following command: ip route 0.0.0.0 0.0.0.0 serial 0/1/1 What is the purpose of this command?. Packets that are received from the Internet will be forwarded to one of the LANs connected to R1 or R2. Packets with a destination network that is not 10.10.0.0/16 or is not 10.20.0.0/16 or is not a directly connected network will be forwarded to the Internet. Packets from the 10.10.0.0/16 network will be forwarded to network 10.20.0.0/16, and packets from the 10.20.0.0/16 network will be forwarded to network 10.10.0.0/16. Packets that are destined for networks that are not in the routing table of HQ will be dropped.

24. What protocol or technology disables redundant paths to eliminate Layer 2 loops?. VTP. STP. EtherChannel. DTP.

25. Refer to the exhibit. Based on the exhibited configuration and output, why is VLAN 99 missing?. because VLAN 99 is not a valid management VLAN. because there is a cabling problem on VLAN 99. because VLAN 1 is up and there can only be one management VLAN on the switch. because VLAN 99 has not yet been created.

26. Which two VTP modes allow for the creation, modification, and deletion of VLANs on the local switch? (Choose two.). client. master. distribution. slave. server. transparent.

27. Which three steps should be taken before moving a Cisco switch to a new VTP management domain? (Choose three.). Configure the switch with the name of the new management domain. Reset the VTP counters to allow the switch to synchronize with the other switches in the domain. Configure the VTP server in the domain to recognize the BID of the new switch. Download the VTP database from the VTP server in the new domain. Select the correct VTP mode and version. Reboot the switch.

28. A network administrator is preparing the implementation of Rapid PVST+ on a production network. How are the Rapid PVST+ link types determined on the switch interfaces?. Link types can only be configured on access ports configured with a single VLAN. Link types can only be determined if PortFast has been configured. Link types are determined automatically. Link types must be configured with specific port configuration commands.

29. Refer to the exhibit. All the displayed switches are Cisco 2960 switches with the same default priority and operating at the same bandwidth. Which three ports will be STP designated ports? (Choose three.). fa0/9. fa0/13. fa0/10. fa0/20. fa0/21. fa0/11.

30. How will a router handle static routing differently if Cisco Express Forwarding is disabled?. It will not perform recursive lookups. Ethernet multiaccess interfaces will require fully specified static routes to avoid routing inconsistencies. Static routes that use an exit interface will be unnecessary. Serial point-to-point interfaces will require fully specified static routes to avoid routing inconsistencies.

31. Compared with dynamic routes, what are two advantages of using static routes on a router? (Choose two.). They improve netw​ork security. They take less time to converge when the network topology changes. They improve the efficiency of discovering neighboring networks. They use fewer router resources.

32. Refer to the exhibit. Which route was configured as a static route to a specific network using the next-hop address?. S 10.17.2.0/24 [1/0] via 10.16.2.2. S 0.0.0.0/0 [1/0] via 10.16.2.2. S 10.17.2.0/24 is directly connected, Serial 0/0/0. C 10.16.2.0/24 is directly connected, Serial0/0/0.

33. What is the effect of entering the spanning-tree portfast configuration command on a switch?. It disables an unused port. It disables all trunk ports. It enables portfast on a specific switch interface. It checks the source L2 address in the Ethernet header against the sender L2 address in the ARP body.

34. What is the IPv6 prefix that is used for link-local addresses?. FF01::/8. 2001::/3. FC00::/7. FE80::/10.

35. Which two statements are characteristics of routed ports on a multilayer switch? (Choose two.)​. In a switched network, they are mostly configured between switches at the core and distribution layers. The interface vlan command has to be entered to create a VLAN on routed ports. They support subinterfaces, like interfaces on the Cisco IOS routers. They are used for point-to-multipoint links. They are not associated with a particular VLAN.

36. Successful inter-VLAN routing has been operating on a network with multiple VLANs across multiple switches for some time. When an inter-switch trunk link fails and Spanning Tree Protocol brings up a backup trunk link, it is reported that hosts on two VLANs can access some, but not all the network resources that could be accessed previously. Hosts on all other VLANS do not have this problem. What is the most likely cause of this problem?. The protected edge port function on the backup trunk interfaces has been disabled. The allowed VLANs on the backup link were not configured correctly. Dynamic Trunking Protocol on the link has failed. Inter-VLAN routing also failed when the trunk link failed.

37. Which command will start the process to bundle two physical interfaces to create an EtherChannel group via LACP?. interface port-channel 2. channel-group 1 mode desirable. interface range GigabitEthernet 0/4 – 5. channel-group 2 mode auto.

38. What action takes place when a frame entering a switch has a multicast destination MAC address?. The switch will forward the frame out all ports except the incoming port. The switch forwards the frame out of the specified port. The switch adds a MAC address table entry mapping for the destination MAC address and the ingress port. The switch replaces the old entry and uses the more current port.

39. A junior technician was adding a route to a LAN router. A traceroute to a device on the new network revealed a wrong path and unreachable status. What should be done or checked?. Verify that there is not a default route in any of the edge router routing tables. Check the configuration on the floating static route and adjust the AD. Create a floating static route to that network. Check the configuration of the exit interface on the new static route.

40. Select the three PAgP channel establishment modes. (Choose three.). auto. default. passive. desirable. extended. on.
