SwitchA receives the frame with the addressing shown in the exhibit.
According to the command output also shown in the exhibit, how will SwitchA handle this frame?
A. It will drop the frame.
B. It will forward the frame out port Fa0/6 only.
C. It will forward the frame out port Fa0/3 only.
D. It will flood the frame out all ports.
E. It will flood the frame out all ports except Fa0/3.
E. It will flood the frame out all ports except Fa0/3.
Explanation:
When frame receives the frame, it checks the source address on MAC table if MAC address found in MAC table it tries to forward if not in MAC table adds the Address on MAC table. After checking the source address, it checks the destination address on MAC table, if MAC address found on MAC table it forwards to proper ports otherwise floods on all ports except the source port.
The exhibit is showing the topology and the MAC address table. Host A sends a data frame to host D.
What will the switch do when it receives the frame from host A?
A. The switch will add the source address and port to the MAC address table and forward the frame to host D.
B. The switch will discard the frame and send an error message back to host A.
C. The switch will flood the frame out of all ports except for port Fa0/3.
D. The switch will add the destination address of the frame to the MAC address table and forward the frame to host D.
A. The switch will add the source address and port to the MAC address table and forward the frame to host D.
Explanation:
When switch receives the data frame from the host not having the MAC address already on the MAC table, it will add the MAC address to source port on MAC address table and sends the data frame.
If the resume command is entered after the sequence that is shown in the exhibit, which router prompt will be displayed?
A. Router1>
B. Router1#
C. Router2>
D. Router2#
C. Router2>
Explanation:
The Ctrl-Shift-6 x command suspends the telnet session and hence the prompt will again be Router2>

A network has been planned as shown.
Which three statements accurately describe the areas and devices in the network plan? (Choose three.)
A. Network Device A is a switch.
B. Network Device B is a switch.
C. Network Device A is a hub.
D. Network Device B is a hub.
E. Area 1 contains a Layer 2 device.
F. Area 2 contains a Layer 2 device.
A. Network Device A is a switch.
D. Network Device B is a hub.
E. Area 1 contains a Layer 2 device.
Explanation:
Switches use a separate collision domain for each port, so device A must be a switch. Hubs, however, place all ports in the same collision domain so device B is a hub. Switches reside in layer 2 while hubs are layer 1 devices.
Refer to the exhibit.
All devices attached to the network are shown.
How many collision domains are present in this network?
A. 2
B. 3
C. 6
D. 9
E. 15
E. 15
Explanation:
A switch uses a separate collision domain for each port so there are a total of 9 for each device shown. In addition to this, the switch to switch connections (3) are a separate collision domain. Finally, we add the switch to router connections (2) and the router to router connection (1) for a total of 15.
Refer to the exhibit.
The ports that are shown are the only active ports on the switch. The MAC address table is shown in its entirety. The Ethernet frame that is shown arrives at the switch.
What two operations will the switch perform when it receives this frame? (Choose two.)
A. The MAC address of 0000.00aa.aaaa will be added to the MAC address table.
B. The MAC address of 0000.00dd.dddd will be added to the MAC address table.
C. The frame will be forwarded out port fa0/3 only.
D. The frame will be forwarded out fa0/1, fa0/2, and fa0/3.
E. The frame will be forwarded out all the active ports.
A. The MAC address of 0000.00aa.aaaa will be added to the MAC address table.
D. The frame will be forwarded out fa0/1, fa0/2, and fa0/3.
Explanation:
If the switch already has the MAC address in its table for the destination, it will forward the frame directly to the destination port. If it was not already in its MAC table, then they frame would have been flooded out all ports except for the port that it came from. It will also add the MAC address of the source device to its MAC address table
Refer to the exhibit.
The MAC address table is shown in its entirety. The Ethernet frame that is shown arrives at the switch.
What two operations will the switch perform when it receives this frame? (Choose two.)
A. The switch will not forward a frame with this destination MAC address.

C. The MAC address of ffff.ffff.ffff will be added to the MAC address table.
D. The frame will be forwarded out all active switch ports except for port fa0/0.
E. The frame will be forwarded out fa0/0 and fa0/1 only.
F. The frame will be forwarded out all the ports on the switch.
B. The MAC address of 0000.00aa.aaaa will be added to the MAC Address Table.
D. The frame will be forwarded out all active switch ports except for port fa0/0.
Explanation:
If the switch already has the MAC address in its table for the destination, it will forward the frame directly to the destination port. If it was not already in its MAC table, then they frame would have been flooded out all ports except for the port that it came from.
Refer to the exhibit.
What must be configured to establish a successful connection from Host A to switch SW-A through router
RT-A?
A. VLAN 1 on RT-A
B. IP routing on SW-A
C. default gateway on SW-A
D. crossover cable connecting SW-A and RT-A
C. default gateway on SW-A
Explanation:
In order for the switch to reach networks that are not local, such as networks attached to different interfaces of the router, it will need to set its default gateway to be the IP address of the attached router.
Refer to the topology and switching table shown in the graphic.
Host B sends a frame to Host C.

Refer to the exhibit.
If CDP is enabled on all devices and interfaces, which devices will appear in the output of a show cdp neighbors command issued from R2?
A. R2 and R3
B. R1 and R3
C. R3 and S2
D. R1, S1, S2, and R3
E. R1, S1, S2, R3, and S3
C. R3 and S2
Explanation:
A Cisco device enabled with CDP sends out periodic interface updates to a multicast address in order to make itself known to neighbors. Since it is a layer two protocol, these packets are not routed. So the devices detected would be immediate connected neighbors.
Refer to the exhibit.
The two routers have had their startup configurations cleared and have been restarted.
At a minimum, what must the administrator do to enable CDP to exchange information between R1 and R2?
A. Configure the router with the cdp enable command.
B. Enter no shutdown commands on the R1 and R2 fa0/1 interfaces.
C. Configure IP addressing and no shutdown commands on both the R1 and R2 fa0/1 interfaces.
D. Configure IP addressing and no shutdown commands on either of the R1 or R2 fa0/1 interfaces.
B. Enter no shutdown commands on the R1 and R2 fa0/1 interfaces.
Explanation:
If the shut down commands are not entered, then CDP can exchange information between the two routers, else it would fail.
Refer to the exhibit.
The network administrator is testing connectivity from the branch router to the newly installed application server.
What is the most likely reason for the first ping having a success rate of only 60 percent?
A. The network is likely to be congested, with the result that packets are being intermittently dropped.
B. The branch router had to resolve the application server MAC address.
C. There is a short delay while NAT translates the server IP address.
D. A routing table lookup delayed forwarding on the first two ping packets.
E. The branch router LAN interface should be upgraded to FastEthernet.
B. The branch router had to resolve the application server MAC address.
Explanation:
Initially the MAC address had to be resolved, but later on it was confirmed to ping went straight away
Refer to the exhibit.
Which two statements are correct? (Choose two.)
A. This is a default route.
B. Adding the subnet mask is optional for the ip route command.
C. This will allow any host on the 172.16.1.0 network to reach all known destinations beyond RouterA.
D. This command is incorrect, it needs to specify the interface, such as s0/0/0 rather than an IP address.
E. The same command needs to be entered on RouterA so that hosts on the 172.16.1.0 network can
reach network 10.0.0.0.
A. This is a default route.
C. This will allow any host on the 172.16.1.0 network to reach all known destinations beyond RouterA.
Explanation:
This is obviously the default value for the route which is set between the routers and since it is entered in such a manner that it ensures connectivity between the stub network and any host lying beyond RouterA.
Refer to the exhibit.
Host A can communicate with Host B but not with Hosts C or D.
How can the network administrator solve this problem?
A. Configure Hosts C and D with IP addresses in the 192.168.2.0 network.
B. Install a router and configure a route to route between VLANs 2 and 3.
C. Install a second switch and put Hosts C and D on that switch while Hosts A and B remain on the original switch.
D. Enable the VLAN trunking protocol on the switch.
B. Install a router and configure a route to route between VLANs 2 and 3.
Explanation:
Two VLANs require a router in between otherwise they cannot communicate through a simple switch mechanism
Refer to the exhibit.
What is the simplest way to configure routing between the regional office network 10.89.0.0/20 and the corporate network?

The junior network support staff provided the diagram as a recommended configuration for the first phase
of a four-phase network expansion project. The entire network expansion will have over 1000 users on 14 network segments and has been allocated this IP address space.
192.168.1.1 through 192.168.5.255
192.168.100.1 through 192.168.100.255
What are three problems with this design? (Choose three.)
A. The AREA 1 IP address space is inadequate for the number of users.
B. The AREA 3 IP address space is inadequate for the number of users.
C. AREA 2 could use a mask of /25 to conserve IP address space.
D. The network address space that is provided requires a single network-wide mask.
E. The router-to-router connection is wasting address space.
F. The broadcast domain in AREA 1 is too large for IP to function.
A. The AREA 1 IP address space is inadequate for the number of users.
C. AREA 2 could use a mask of /25 to conserve IP address space.
E. The router-to-router connection is wasting address space.
Explanation:
The given IP addresses of areas 1 and 3 along with network masks of 24 cannot accommodate 500 users so are inadequate, while the area 2 is having over capacity so its network mask can be reduced to 25 to accommodate the only 60 users it has.
Refer to the exhibit.
If the hubs in the graphic were replaced by switches, what would be virtually eliminated?
A. broadcast domains
B. repeater domains
C. Ethernet collisions
D. signal amplification
E. Ethernet broadcasts
C. Ethernet collisions
Explanation:
Modern wired networks use a network switch to eliminate collisions. By connecting each device directly to a port on the switch, either each port on a switch becomes its own collision domain (in the case of half duplex links) or the possibility of collisions is eliminated entirely in the case of full duplex links.
Refer to the exhibit.
If host A sends an IP packet to host B, what will the source physical address be in the frame when it reaches host B?

C. A1:A1:A1:A1:A1:A1
D. B2:B2:B2:B2:B2:B2
E. C3:C3:C3:C3:C3:C3
F. D4:D4:D4:D4:D4:D4
E. C3:C3:C3:C3:C3:C3
Explanation:
When packets transfer from one host to another across a routed segment, the source IP address always remains the same source IP address, and the source physical (MAC) address will be the existing router’s interface address. Similarly, the destination IP address always remains the same and the destination physical (MAC) address is the destination router’s interface address.
Refer to the exhibit.
HostX is transferring a file to the FTP server. Point A represents the frame as it goes toward the Toronto router.
