,Refer to the exhibit. What will router R1 do with a packet that has a destination IPv6
address of 2001:db8:cafe:5::1? - ANSWERForward 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? - ANSWERip 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? -
ANSWERChange the destination network and mask to 0.0.0.0 0.0.0.0
Which option shows a correctly configured IPv4 default static route? - ANSWERip 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? - ANSWERipv6 route 2001:db8:12:10::/64 s0/0/1 fe80::2
What is a method to launch a VLAN hopping attack? - ANSWERIntroducing 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? - ANSWERMAC 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? -
ANSWERThe 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? - ANSWERThe virtual IP
address and the virtual MAC address for the HSRP group 1
Match the forwarding characteristic to its type - ANSWERCut-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? - ANSWERFrame 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? - ANSWERThe broadcast domain expands to all switches
Match the link state to the interface and protocol status - ANSWERDisabled-
Administratively down
Layer 1 problem- down/down
Layer 2 problem- up/down
Operational- up/up
Match the step to each switch boot process description. - ANSWERStep 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? - ANSWERSW 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? -
ANSWERBecause 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. - ANSWERDefault 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
