NEW QUESTION # 122
What is the attenuation value of a human body on a wireless signal?
- A. 4 dB
- B. 3 dB
- C. 12 dB
- D. 6 dB
Answer: B
Explanation:
Signal Attenuation
Signal attenuation or signal loss occurs even as the signal passes through air. The loss of signal strength is more pronounced as the signal passes through different objects. A transmit power of
20 mW is equivalent to 13 dBm. Therefore, if the transmitted power at the entry point of a plasterboard wall is at 13 dBm, the signal strength is reduced to 10 dBm when exiting that wall.
This table shows the likely loss in signal strength caused by various types of objects.

NEW QUESTION # 123
Which of the following statements best describes the purpose of ARP with respect to CEF?
- A. ARP is used to build the FIB.
- B. ARP is used to build the adjacency table.
- C. ARP is used to decrease the amount of time spent searching for an entry within a routing table.
- D. ARP is used to reindex the routing table.
Answer: B
Explanation:
Address Resolution Protocol (ARP) is used by Cisco Express Forwarding (CEF) to build the adjacency table.
CEF is the switching method used by Catalyst switches. Unlike traditional multilayer switching (MLS), which merely caches Layer 3 information received when traffic passes through a switch, CEF attempts to optimize the routing process by reindexing the routing table and then building an adjacency table based on the routing table information. The type of MLS performed by CEF is called topology-based switching; traditional MLS is known as route caching, demand-based switching, and flow-based switching.
The routing table is reindexed by using a binary search method. The reindexed routing table is called the forwarding information base (FIB). Reindexing the routing table reduces the amount of time spent searching for an entry within a routing table.
After the FIB is created, an adjacency table is created to map the appropriate Layer 2 next-hop address or addresses to each FIB entry. ARP is used to retrieve the Layer 2 address information. If multiple Layer 2 next- hop addresses are available for an entry in the FIB, then CEF can employ load balancing for packets headed to that destination.
The final result is a single database of routing information (FIB) is built for the switching hardware.
Two extremely useful commands for verifying CEF are:
show ip cef network address - displays entries in the forwarding information base (FIB) show adjacency detail | begin adjacency address - shows information about a specific adjacency in the adjacency table Both commands are shown below with explanations.
SwitchA# show ip cef 192.168.6.0
192.168.6.0/24, version 302, cached adjacency 192.168.166.5, 0 packets, 0 bytes Via 192.168.166.5, VLAN 185, 0 dependencies Next-hop 192.168.166.5, VLAN 185 Valid cached adjacency Above it can be determined that there is a valid CEF entry for the destination network 192.168.6.0 and that there is a valid cached adjacency to the 192.168.166.5 next hop IP address.
In the command output below, it can be determined that 005565946856 is the MAC address of the
192.168.166.5 next-hop address:
SwitchA# show adjacency detail | begin 192.168.166.5
IP VLAN 185 192.168.166.5(6) 0 packets, 0 bytes
005565946856

NEW QUESTION # 124
Which three pieces of equipment are needed to conduct a fully measured wireless survey? (Choose three.)
- A. goggles
- B. PoE battery
- C. ladder
- D. tall tripod
- E. access point
- F. spirit level
Answer: B,C,E
Explanation:
A fully measured wireless survey requires tools that support the active functioning of the network and allow for physical access to install and measure equipment. A PoE (Power over Ethernet) battery is necessary to power the access point during the survey. The access point itself is essential for broadcasting the signal. A ladder is needed to reach high places for proper access point placement and to measure coverage areas effectively.

NEW QUESTION # 125
How does AP failover priority for access points function when configured with priority 1 or 4?
- A. When configured with priority 4, the access point is assigned with the highest priority level and it is marked as critical. This access point fails over before other access points with the lower priority when there is primary controller failure.
- B. When configured with priority 1, the access point is assigned with the highest priority level and it is marked as critical. This access point fails over before other access points with the lower priority when there is primary controller failure.
- C. When configured with priority 1, the access point is assigned with the medium priority level and it is marked as medium. This access point fails over after other access points with the higher priority when there is primary controller failure.
- D. When configured with priority 4, the access point is assigned with the lowest priority level and it is marked as low. This access point fails over after other access points with the higher priority when there is primary controller failure.
Answer: A
NEW QUESTION # 126

NEW QUESTION # 127
Guest anchoring is configured for a newly created SSID for your company. It has been noticed that the mobility tunnels are not up, and that MPING fails from your foreign WLC to the anchor WLC. What is the reason that it is failing?
- A. A rule is needed at the firewall to allow UDP port 16666 for communication towork.
- B. A rule is needed at the firewall to allow UDP port 97 for communication to work.
- C. A rule is needed at the firewall to allow TCP port 97 for communication to work.
- D. A rule is needed at the firewall to allow TCP port 16666 for communication to work.
Answer: A
Explanation:
Guest anchoring requires mobility tunnels to be established between the foreign and anchor WLCs. For these tunnels to function, the firewall must allow specific ports for communication. UDP port 16666 is the port used for mobility traffic in Cisco wireless networks, and if it is not allowed through the firewall, MPING and mobility tunnels will fail.

NEW QUESTION # 128
A customer requires that two wireless APs be installed in a reception area, in a historic building, the impact of the APs on the appearance of the reception area must be minimized. Which two AP antennas should be used?
(Choose two.)
- A. AP with a monopole antenna
- B. AP with a dipole antenna
- C. AP with a patch antenna
- D. AP with an integrated antenna
- E. AP with a Yagi antenna
Answer: C,D
Explanation:
In a historic building where aesthetics are important, using APs with integrated antennas can minimize visual impact as they are often designed to be compact and less conspicuous. Patch antennas are also a good choice as they can be mounted flat against surfaces, blending in with the environment while providing directional coverage.
