SRWE Final Exam Q's 1-60

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

• • forward the packet out GigabitEthernet0/0

• • drop the packet

• • forward the packet out GigabitEthernet0/1

• forward the packet out Serial0/0/0

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?

• • ip route 10.10.0.0 255.255.0.0 Serial 0/0/0 100

• • ip route 10.10.0.0 255.255.0.0 209.165.200.226 100

• ip route 10.10.0.0 255.255.0.0 209.165.200.225 100

• • ip route 10.10.0.0 255.255.0.0 209.165.200.225 50

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?

• • 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.

4. 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 0.0.0.0 S0/0/0

• • ip route 0.0.0.0 255.255.255.255 S0/0/0

• • ip route 0.0.0.0 255.0.0.0 S0/0/0

5. 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

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

• • 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

6. What is a method to launch a VLAN hopping attack?

• • introducing a rogue switch and enabling trunking

• • sending spoofed native VLAN information

• • sending spoofed IP addresses from the attacking host

• • flooding the switch with MAC addresses

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?

• • VLAN hopping

• • DHCP spoofing

• MAC address table overflow

• • VLAN double-tagging

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?

• • The default gateway address is not provided in the pool.

• • No clients have communicated with the DHCPv6 server yet.

• • The IPv6 DHCP pool configuration has no IPv6 address range specified.

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

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?

• 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

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

• • the IP address and the MAC address of R1

Characteristics of cut-trough forwarding (Choose 3)

• appropriate for high performance computing applications

• error checking before forwarding

• forwarding process can begin after receiving the destination address

• may forward invalid frames

• only forwards valid frames
