Refer to the exhibit. What will router R1 do with a packet that has a destination IPv6 address of
2001:db8:cafe:5::1? - (ANSWER)Forward the packet out Serial 0/0/0
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)ip route 10.10.0.0
255.255.0.0 209.165.200.225 100
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 the network 172.16.0.0/16 are unable to reach
resources on the Internet. How should this static router be changed to allow user traffic from the LAN to
reach the Internet? - (ANSWER)Change the destination network and mask to 0.0.0.0 0.0.0.0
Which option shows a correctly configured IPv4 default static route? - (ANSWER)ip route 0.0.0.0 0.0.0.0
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? - (ANSWER)ipv6 route 2001:db8:12:10::/64 s0/0/1 fe80::2
What is a method to launch a VLAN hopping attack? - (ANSWER)Introducing a rouge switch and enabling
trunking
A cybersecurity analyst is using the macof tool to evaluate configurations of switches deployed in the
backbone network for an organization. Which type of LAN attack is the analyst targeting during the
evaluation? - (ANSWER)MAC address table overflow
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 the number of active clients is 0? - (ANSWER)The state is not maintained by the
DHCPv6 server under stateless DHCPv6 operation

Refer to the exhibit. A network administrator configured routers R1 an 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)The virtual IP address
and the virtual MAC address for the HSRP group 1
Match the forwarding characteristic to its type - (ANSWER)Cut-through:
-Appropriate for high performance computing applications
-Forwarding process can begin after receiving the destination address
-May forward invalid frames
Store-and-forward:
-Error checking before forwarding
-Forwarding process only begins after receiving the entire frame
-Only forwards valid frames
Which statement is correct about how a Layer 2 switch determines how to forward frames? -
(ANSWER)Frame forwarding decisions are based on MAC address and port mappings in the CAM table
Which statement describes a result after multiple Cisco LAN switches are interconnected? -
(ANSWER)The broadcast domain expands to all switches
Match the link state to the interface and protocol status - (ANSWER)Disabled- Administratively down
Layer 1 problem- down/down
Layer 2 problem- up/down
Operational- up/up
Match the step to each switch boot process description. - (ANSWER)Step 1- Execute POST

Step 2- Load the boot loader from the ROM
Step 3- CPU register initializations
Step 4- Flash the file system initialization
Step 5- Load the IOS
Step 6- Transfer switch control to the IOS
Refer to the exhibit. How is a frame sent from PC-A forward to PC-C if the MAC address table on switch
SW1 is empty? - (ANSWER)SW floods the frame on all the ports on SW1, excluding the port through
which the frame entered the switch
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 that VLANs 10 and 100 still exist on
the switch. Why were these VLANs not removed? - (ANSWER)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
Match the description to the correct VLAN type. - (ANSWER)Default VLAN- All switchports are assigned
to this VLAN after initial bootup of the switch
Management VLAN- An IP address and subnet mask are assigned to this VLAN, allowing the switch to be
accessed by HTTP, Telnet, SSH, or SNMP
Data VLAN- Configured to carry user generated traffic
Native VLAN- Carries untagged traffic
Refer to the exhibit. A network administrator has connected two switches together using EtherChannel
technology. If STP is running, what will be the end result? - (ANSWER)STP will block one of the redundant
links
What is a secure configuration option for remote access to a network device? - (ANSWER)Configure SSH
Which wireless encryption method is the most secure? - (ANSWER)WPA2 with AES
