ccna2 theory 1-15

Question 1

refer to exhibit. What will router R1 do with a packet that has a destination IPv6 address of 2001:db8:cafe:5::1

Answer 1

forward the packet out serial0/0/0

Question 2

Refer to the exhibit. Currently router R1 uses an EIGRP route learned from Branch2 to reach the 10.10.0.0/16 network. Which floating static route would create a backup route to the 10.10.0.0/16 network in the event that the link between R1 and Branch2 goes down?

Answer 2

ip route 10.10.0.0 255.255.0.0 209.165.200.225 100

Question 3

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?

Answer 3

Change the destination network and mask to 0.0.0.0 0.0.0.0

Question 4

Which option shows a correctly configured IPv4 default static route?

Answer 4

ip route 0.0.0.0 0.0.0.0 S0/0/0

Question 5

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

Answer 5

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

Question 6

What is a method to launch a VLAN hopping attack?

Answer 6

introducing a rogue switch and enabling trunking

Question 7

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?

Answer 7

MAC address table overflow

Question 8

Refer to the exhibit. A network administrator is configuring a router as a DHCPv6 server. The administrator issues a show ipv6 dhcp pool command to verify the configuration. Which statement explains the reason that the number of active clients is 0?

Answer 8

The state is not maintained by the DHCPv6 server under stateless DHCPv6 operation.

Question 9

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?

Answer 9

the virtual IP address and the virtual MAC address for the HSRP group 1

Question 10

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

Answer 10

Frame forwarding decisions are based on MAC address and port mappings in the CAM table.

Question 11

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

Answer 11

The broadcast domain expands to all switches.

Question 12

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

Answer 12

disabled = administratively down, layer1 problem = down/down, layer 2 problem = up/down, operational = up/up

Question 13

Refer to the exhibit. How is a frame sent from PCA forwarded to PCC if the MAC address table on switch SW1 is empty?

Answer 13

SW1 floods the frame on all ports on SW1, excluding the port through which the frame entered the switch.

Question 14

An administrator is trying to remove configurations from a switch. After using the command erase startup-config and reloading the switch, the administrator finds that VLANs 10 and 100 still exist on the switch. Why were these VLANs not removed?

Answer 14

Because these VLANs are stored in a file that is called vlan.dat that is located in flash memory, this file must be manually deleted.
