CISCO 2 FINAL EXAM Part 1/3

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

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

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.

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?

• 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.

• These VLANs cannot be deleted unless the switch is in VTP client mode.

• These VLANs are default VLANs that cannot be removed.

• These VLANs can only be removed from the switch by using the no vlan 10 and no vlan 100 commands.

What is a secure configuration option for remote access to a network device?

• Configure an ACL and apply it to the VTY lines.

• Configure 802.1x.

• Configure SSH.

• Configure Telnet.

Which wireless encryption method is the most secure?

• WPA2 with AES

• WPA2 with TKIP

• WEP

• WPA

After attaching four PCs to the switch ports, configuring the SSID and setting authentication properties for a small office network, a technician successfully tests the connectivity of all PCs that are connected to the switch and WLAN. A firewall is then configured on the device prior to connecting it to the Internet. What type of network device includes all of the described features?

• firewall appliance

• wireless router

• switch

• standalone wireless access point

What protocol or technology disables redundant paths to eliminate Layer 2 loops?

• VTP

• STP

• EtherChannel

• DTP

Which two VTP modes allow for the creation, modification, and deletion of VLANs on the local switch? (Choose two.)

• master

• distribution

• slave

• server

• transparent
