Finale Exam 50-100

51 Which network attack is mitigated by enabling BPDU guard?

• rogue switches on a network

• CAM table overflow attacks

• MAC address spoofing

• rogue DHCP servers on a network

52. Why is DHCP snooping required when using the Dynamic ARP Inspection feature?

• It relies on the settings of trusted and untrusted ports set by DHCP snooping.

• It uses the MAC address table to verify the default gateway IP address.

• It redirects ARP requests to the DHCP server for verification.

• It uses the MAC-address-to-IP-address binding database to validate an ARP packet.

Refer to the exhibit. Router R1 has an OSPF neighbor relationship with the ISP router over the 192.168.0.32 network. The 192.168.0.36 network link should serve as a backup when the OSPF link goes down. The floating static route command ip route 0.0.0.0 0.0.0.0 S0/0/1 100 was issued on R1 and now traffic is using the backup link even when the OSPF link is up and functioning. Which change should be made to the static route command so that traffic will only use the OSPF link when it is up?​

• Change the administrative distance to 120.

• Add the next hop neighbor address of 192.168.0.36.

• Change the destination network to 192.168.0.34.

• Change the administrative distance to 1.

54 Refer to the exhibit. What is the metric to forward a data packet with the IPv6 destination address 2001:DB8:ACAD:E:240:BFF:FED4:9DD2?

• 90

• 2170112

• 2681856

• 2682112

• 3193856

55. A network administrator is configuring a new Cisco switch for remote management access. Which three items must be configured on the switch for the task? (Choose three.)

• VTP domain

• IP address

• default VLAN

• vty lines

56. Refer to the exhibit. Which statement shown in the output allows router R1 to respond to stateless DHCPv6 requests?

• ipv6 nd other-config-flag​

• prefix-delegation 2001:DB8:8::/48 00030001000E84244E70​

• ipv6 dhcp server LAN1​

• ipv6 unicast-routing

57. Refer to the exhibit. A Layer 3 switch routes for three VLANs and connects to a router for Internet connectivity. Which two configurations would be applied to the switch? (Choose two.)

• (config)# interface gigabitethernet 1/1

  (config-if)# no switchport

  (config-if)# ip address 192.168.1.2 255.255.255.252

• (config)# interface vlan 1(config-if)# ip address 192.168.1.2 255.255.255.0(config-if)# no shutdown

• (config)# ip routing

• (config)# interface fastethernet0/4(config-if)# switchport mode trunk

58. A technician is troubleshooting a slow WLAN and decides to use the split-the-traffic approach. Which two parameters would have to be configured to do this? (Choose two.)

• Configure the security mode to WPA Personal TKIP/AES for one network and WPA2 Personal AES for the other network

• Configure a common SSID for both split networks.

• Configure the 5 GHz band for streaming multimedia and time sensitive traffic.

• configure the 2.4 GHz band for basic internet traffic that is not time sensitive.

59. A company has just switched to a new ISP. The ISP has completed and checked the connection from its site to the company. However, employees at the company are not able to access the internet. What should be done or checked?

• Verify that the static route to the server is present in the routing table.

• Check the configuration on the floating static route and adjust the AD.

• Ensure that the old default route has been removed from the company edge routers.

• Create a floating static route to that network.

60. Which information does a switch use to populate the MAC address table?

• the destination MAC address and the incoming port

• the destination MAC address and the outgoing port

• the source and destination MAC addresses and the

• the source MAC address and the incoming port
