1.
Refer to the exhibit. What happens when a frame from a source MAC address different from 00a8.d2e4.ba27 reaches switch port 0/5? The frame is dropped.
The port is shut down.
An error message is displayed.
FastEthernet port 0/5 will show an err-disabled message.
2.
Refer to the exhibit. What will allow a host on VLAN 40 on switch X to communicate with a host in VLAN 40 on switch Y? QoS
routing
trunking
VPN
3. A network administrator issued the erase nvram: command on a switch. What will be the outcome of the command? It will clear the contents of the MAC table.
It will clear the contents of the VLAN database.
It will clear the contents of the startup configuration file. It will clear the contents of the running configuration file. 4. What type of message do wireless clients transmit when they are searching for a specific wireless network? probe

beacon
associate
authenticate
5. What are two requirements for configuring inter-VLAN routing using the router-on-a-stick model? (Choose two.) Each subinterface should be configured with its own IP address, subnet mask, and unique VLAN assignment. The physical interface of the router must be connected to a trunk link on the adjacent switch. The number of physical interfaces on the router should match the number of VLANs. Different static VLANs should be assigned to different interfaces of the router. The router should be configured as the VTP server.

6.
Refer to the exhibit. A network administrator needs to add IP phones to the network. To which devices should the IP phones connect? AS1 and AS2
DS1 and DS2
DS1, DS2, and CS1
AS1, AS2, DS1, and DS2
7. A network administrator enters the enable command at the Switch> prompt of a new switch. What mode will the switch enter? setup mode
configuration mode
privileged EXEC mode
user EXEC mode
ROMMON mode
interface mode
8.
Refer to the exhibit. What does the term DYNAMIC indicate in the output that is shown? This entry can only be removed from the MAC address table by a network administrator. When forwarding a frame to the device with address 0060.5c5b.cd23, the switch does not have to perform a lookup to determine the final destination port. Only the device with MAC address 0060.5c5b.cd23 will be allowed to connect to port Fa0/18. The switch learned this MAC address from the source address in a frame received on Fa0/18. 9. Which value determines if a switch becomes the central point of reference in the spanning tree topology? lowest bridge ID

highest revision number
lowest numeric IP address
highest numeric MAC address
10.
Refer to the exhibit. Users A and B are reporting intermittent connectivity problems. Pre-installation surveys showed strong signal strength from the AP locations to the client locations. Outside electrical interference has been eliminated. What will fix the problem? Relocate the APs closer to each other.

Increase the distance between the clients.
Change the channel on AP-B to 6 or 11.
Place AP-A and AP-B on the same wireless channel.
11.
Refer to the exhibit. Router RA receives a packet with a source address of 192.168.1.65 and a destination address of 192.168.1.161. What will the router do with this packet? The router will drop the packet.

The router will forward the packet out interface FastEthernet 0/1.1. The router will forward the packet out interface FastEthernet 0/1.2. The router will forward the packet out interface FastEthernet 0/1.3. The router will forward the packet out interface FastEthernet 0/1.2 and interface FastEthernet 0/1.3. 12.

Refer to the exhibit. R1 is configured for traditional inter-VLAN routing. R1 can ping computer 3 but cannot ping computer 1. What is a possible cause for this failure? S1 port Fa0/11 is in the wrong VLAN.

R1 does...
