CCNA v7.0 41-60

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.)

• 1. execute POST

• 2. load the boot loader from ROM

• 3. CPU register initializations

• 4. flash file system initialization

• 5. load the IOS 6. transfer switch control to the IOS

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.

46. What is the common term given to SNMP log messages that are generated by network devices and sent to the SNMP server?

• traps

• acknowledgments

• auditing

• warnings

47. A network administrator is adding a new WLAN on a Cisco 3500 series WLC. Which tab should the administrator use to create a new VLAN interface to be used for the new WLAN?

• WIRELESS

• MANAGEMENT

• CONTROLLER

• WLANs

48. A network administrator is configuring a WLAN. Why would the administrator change the default DHCP IPv4 addresses on an AP?

• to restrict access to the WLAN by authorized, authenticated users only

• to monitor the operation of the wireless network

• to reduce outsiders intercepting data or accessing the wireless network by using a well-known address range

• to reduce the risk of interference by external devices such as microwave ovens

49. Which two functions are performed by a WLC when using split media access control (MAC)? (Choose two.)

• packet acknowledgments and retransmissions

• frame queuing and packet prioritization

• beacons

• frame translation to other protocols

• association and re-association of roaming clients

50. On what switch ports should BPDU guard be enabled to enhance STP stability?

• all PortFast-enabled ports

• only ports that are elected as designated ports

• only ports that attach to a neighboring switch

• all trunk ports that are not root ports
