Test CCNA Final

Refer to the exhibit. R1 was configured with the static route command ip route 209.165.200.224 255.255.255.224 S0/0/0 and consequently users on network 172.16.0.0/16 are unable to reach resources on the Internet. How should this static route be changed to allow user traffic from the LAN to reach the Internet?

• Add an administrative distance of 254.
• Change the destination network and mask to 0.0.0.0 0.0.0.0
• Change the exit interface to S0/0/1.
• Add the next-hop neighbor address of 209.165.200.226.

Which option shows a correctly configured IPv4 default static route?

• ip route 0.0.0.0 255.255.255.0 S0/0/0
• ip route 0.0.0.0 255.255.255.255 S0/0/0
• ip route 0.0.0.0 0.0.0.0 S0/0/0
• ip route 0.0.0.0 255.0.0.0 S0/0/0

Refer to the exhibit. Which static route command can be entered on R1 to forward traffic to the LAN connected to R2?

• ipv6 route 2001:db8:12:10::/64 S0/0/0 fe80::2
• ipv6 route 2001:db8:12:10::/64 S0/0/1 2001:db8:12:10::1
• ipv6 route 2001:db8:12:10::/64 S0/0/1 fe80::2
• ipv6 route 2001:db8:12:10::/64 S0/0/0

What is a method to launch a VLAN hopping attack?

• sending spoofed IP addresses from the attacking host
• sending spoofed native VLAN information
• introducing a rogue switch and enabling trunking
• flooding the switch with MAC addresses

A cybersecurity analyst is using the macof tool to evaluate configurations of switches deployed in the backbone network of an organization. Which type of LAN attack is the analyst targeting during this evaluation?

• VLAN double-tagging
• DHCP spoofing
• MAC address table overflow
• VLAN hopping

Refer to the exhibit. A network administrator configured routers R1 and R2 as part of HSRP group 1. After the routers have been reloaded, a user on Host1 complained of lack of connectivity to the Internet The network administrator issued the show standby brief command on both routers to verify the HSRP operations. In addition, the administrator observed the ARP table on Host1. Which entry should be seen in the ARP table on Host1 in order to gain connectivity to the Internet?

• the IP address and the MAC address of R1
• the virtual IP address of the HSRP group 1 and the MAC address of R2
• the virtual IP address and the virtual MAC address for the HSRP group 1
• the virtual IP address of the HSRP group 1 and the MAC address of R1

Match the forwarding characteristic to its type. (Not all options are used.)

• Cut-through frame forwarding ensures that invalid frames are always dropped.
• Only frames with a broadcast destination address are forwarded out all active switch ports.
• Unicast frames are always forwarded regardless of the destination MAC address.
• Frame forwarding decisions are based on MAC address and port mappings in the CAM table.

Which statement is correct about how a Layer 2 switch determines how to forward frames?

• Only frames with a broadcast destination address are forwarded out all active switch ports.
• Cut-through frame forwarding ensures that invalid frames are always dropped.
• Frame forwarding decisions are based on MAC address and port mappings in the CAM table.
• Unicast frames are always forwarded regardless of the destination MAC address.

Which statement describes a result after multiple Cisco LAN switches are interconnected?

• Frame collisions increase on the segments connecting the switches.
• The broadcast domain expands to all switches.
• Unicast frames are always forwarded regardless of the destination MAC address.
• One collision domain exists per switch.
• There is one broadcast domain and one collision domain per switch.

Match the link state to the interface and protocol status. (Not all options are used.)

• SW1 drops the frame because it does not know the destination MAC address.
• 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 floods the frame on all ports on SW1, excluding the port through which the frame entered the switch.
• SW1 forwards the frame directly to SW2. SW2 floods the frame to all ports connected to SW2, excluding the port through which the frame entered the switch.
