S & R Final Part 2

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.

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

Configure SSH.

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.

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.

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 floods the frame on all ports on SW1, excluding the port through which the frame entered the switch.

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

The broadcast domain expands to all switches.

Which wireless encryption method is the most secure?

WPA2 with AES

Match the description to the correct VLAN type. (Not all options are used.)

default VLAN- configured to carry user generated traffic management VLAN- an IP address and subnet mask are assigned to this VLAN data VLANs- configured to carry user generated traffic native VLAN- carries untagged traffic

Match the link state to the interface and protocol status. (Not all options are used.)

disabled- administratively down Layer 1 problem- down/down Layer 2 problem- up/down operational- up/up

Match the step to each switch boot sequence description. (Not all options are used.)

step 1- execute POST step 2- load the boot loader from ROM step 3- CPU register initializations step 4- flash file system initialization step 5- load the IOS step 6- transfer switch control to the IOS
