QUESTION 1
Which address type does a switch use to make selective forwarding decisions?
A. Source IP address
B. Destination IP address
C. Source and destination IP address
D. Source MAC address
E. Destination MAC address
Correct Answer: E

Explanation:
Switches analyze the destination MAC to make its forwarding decision since it is a layer 2 device. Routers use the destination IP address to make forwarding decisions.

QUESTION 2
Which two VLANs are reserved for system use only? (Choose two)
A. 1
B. 4095
C. 4096
D. 0
E. 1001
Correct Answer: BD

Explanation:
The VLANs 0 and 4095 are reserved by the IEEE 802.1Q standard and you cannot create, delete, or modify them so they are the correct answers.
Note:
+

QUESTION 8
Scenario:
You are a junior network engineer for a financial company, and the main office network is experiencing network issues. Troubleshoot the network issues.
Router R1 connects the main office to the internet, and routers R2 and R3 are internal routers.
NAT is enabled on router R1.
The routing protocol that is enabled between routers R1, R2 and R3 is RIPv2.
R1 sends the default route into RIPv2 for the internal routers to forward internet traffic to R1.
You have console access on R1, R2 and R3 devices. Use only show commands to troubleshoot the issues.



Users complain that they are unable to reach internet sites. You are troubleshooting internet connectivity problem at main office. Which statement correctly identifies the problem on Router R1?
A. Interesting traffic for NAT ACL is incorrectly configured.
B. NAT configurations on the interfaces are incorrectly configured
C. NAT translation statement incorrectly configured.
D. Only static NAT translation configured for the server, missing Dynamic NAT or Dynamic NAT overloading for internal networks.

QUESTION 9
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.
B. The MAC address of 0000.00aa.aaaa will be added to the MAC Address Table.
C. The MAC address of ffff.ffff.ffff will be added to the MAC address table.
D. The frame will be forwarded out of all the active switch ports except for port fa0/0.
E. The frame will be forwarded out of fa0/0 and fa0/1 only.
F. The frame will be forwarded out of all the ports on the switch.
Correct Answer: BD

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.
