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

• desirable

• on

• extended

41. A static route has been configured on a router. However, the destination network no longer exists. What should an administrator do to remove the static route from the routing table?

• Remove the route using the no ip route command.

• Change the administrative distance for that route.

• Change the routing metric for that route.

• Nothing. The static route will go away on its own.

42. Refer to the exhibit. What can be concluded about the configuration shown on R1?

• R1 is configured as a DHCPv4 relay agent.

• R1 is operating as a DHCPv4 server.

• R1 will broadcast DHCPv4 requests on behalf of local DHCPv4 clients.

• R1 will send a message to a local DHCPv4 client to contact a DHCPv4 server at 10.10.10.8.

43. Match the step to each switch boot sequence description. (Not all options are used. Просто запомни)

• Запомнил

• Не запомнил

44. Refer to the exhibit. R1 has been configured as shown. However, PC1 is not able to receive an IPv4 address. What is the problem?​

• The ip helper-address command was applied on the wrong interface.

• R1 is not configured as a DHCPv4 server.​

• A DHCP server must be installed on the same LAN as the host that is receiving the IP address.

• The ip address dhcp command was not issued on the interface Gi0/1.

45. What two default wireless router settings can affect network security? (Choose two.)

• The SSID is broadcast.

• MAC address filtering is enabled.

• WEP encryption is enabled.

• The wireless channel is automatically selected.

• A well-known administrator password is set.
