- Question
If a switch receives a frame and the source MAC address is not in the MAC address table but the destination address is, what will the switch do with the frame?
Options- A. Discard it and send an error message back to the originating host
- B. Flood the network with the frame
- C. Add the source address and port to the MAC address table and forward the frame out the destination port
- D. Add the destination to the MAC address table and then forward the frame
- Correct Answer
- Add the source address and port to the MAC address table and forward the frame out the destination port
ExplanationSince the source MAC address is not in the MAC address table, the switch will add the source address and the port it is connected to into the MAC address table and then forward the frame to the outgoing port. - 1. What is the maximum distance running the lowest data rate for 802.11a?

Correct Answer: About 175 feet
Explanation:
The IEEE 802.11a standard's lowest data rate is 6Mbps, but it can run from a distance of about 175 feet.
Correct Answer: Outside local
Explanation:
The host on the global network before translation is considered to be an outside local host.
Correct Answer: show access-lists
Explanation:
To see the contents of all access lists, use the
show access-lists command.
Correct Answer: TCP
Explanation:
Although Telnet does use TCP and IP (TCP/IP), the question specifically asks about layer 4, and IP works at layer 3. Telnet uses TCP at layer 4.
Correct Answer: NCP
Explanation:
Network Control Protocol is used to help identify the Network layer protocol used in the packet.
Correct Answer: access-list 110 permit tcp any host 1.1.1.1 eq smtp
Explanation:
When trying to find the best answer to an access-list question, always check the access-list number and then the protocol. When filtering to an upper-layer protocol, you must use an extended list, numbers 100-199 and 2000-2699. Also, when you filter to an upper-layer protocol, you must use either
tcp or
udp in the protocol field. If it says
ip in the protocol field, you cannot filter to an upper-layer protocol. SMTP uses TCP.
Correct Answer: The packet will be discarded.
Explanation:
Since the routing table shows no route to the 192.168.22.0 network, the router will discard the packet and send an ICMP destination unreachable message out interface FastEthernet 0/0, which is the source LAN where the packet originated from.
Correct Answer: 3 and 4
Explanation:
IPv4 addresses are 32 bits long and are represented in decimal format. IPv6 addresses are 128 bits long and represented in hexadecimal format.
Correct Answer: By default, all VLANs are allowed on the trunk.
Explanation:
By default, all VLANs are allowed on the trunk link and you must remove by hand each VLAN that you don't want traversing the trunked link.
Correct Answer: The split-MAC architecture allows the splitting of 802.11 protocol packets between the AP and the controller to allow processing by both devices.
Explanation:
The split-MAC architecture allows the splitting of 802.11 protocol packets between the Cisco LWAPP-based AP, which handles real-time portions of the protocol, and the WLAN controller, which handles those items that are not time sensitive.
