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

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

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

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

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

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

• 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.

• Cut-through frame forwarding ensures that invalid frames are always dropped.

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

• The broadcast domain expands to all switches.

• One collision domain exists per switch.

• There is one broadcast domain and one collision domain per switch.

• Frame collisions increase on the segments connecting the switches.

• Unicast frames are always forwarded regardless of the destination MAC address.

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

• 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.

• 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 drops the frame because it does not know the destination MAC address

Which wireless encryption method is the most secure?

• WPA2 with AES

• WPA2 with TKIP

• WEP

• WPA

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?

• STP will block one of the redundant links.

• The switches will load balance and utilize both EtherChannels to forward packets.

• The resulting loop will create a broadcast storm.

• Both port channels will shutdown.
