Answer: C

You have been hired to install new Cisco switches at ACME Corporation. The company has an existing Cisco network comprised of access layer switches that use multiple VLANs and VLAN trunking protocol to distribute the VLANs to the switches throughout the network.
Which two methods are best to accomplish your task? (Choose two.)

A.    Configure the VLAN Trunking Protocol pruning on the new switches because they may not
need all of the VLANs.
B.    Prior to installation, ensure that all switches are running the same Cisco IOS software version as the VTP server.
C.    Ensure that all the new Cisco switches have their VTP domain name set to the default value of “null”
D.    Configure one of the new switches as a VTP server to distribute the VLANs appropriately.
E.    Ensure that all switches are running the same VTP version.
F.    Ensure that all switches have the same VLAN Trunking Protocol password and encryption level.
G.    Configure all new switches as VTP clients and relocated switches as VTP server because they already have all the VLANs in their database.

Answer: CE

You are the network administrator for ACME corporation.
Your organization has deployed a single
Cisco 5500 Series Wireless Controller with 100 Cisco Aironet 3500 Series Aps.

A.    The WLC has been recently rebooted, which causes the TPC algorithm to set power level 3 on
all APs for 90 seconds.
B.    The controller TPC algorithm seems to have a problem. It might have been set to work in TPCv2 mode instead of TPCv1.
C.    The WLC is misconfigured because the static power of level 3 has been set for all the APs under TPC settings.

Answer: C

Which statement about a Cisco Mesh Network when a radar event is detected by the MAP on a mesh tree when coordinated channel change is enabled Is true?

A.    The MAP immediately stops transmission on the current channel and joins the parent again after 30 minutes after the channel is marked as clean.
B.    The MAP continues transmission of the beacons and probes for 10 seconds after the radar detection and suspends operation for the next 30 mins.
C.    The MAP propagates radar event information to the RAP in the same BGN. Searchs for a different parent working on a nono-dfs channel and join there.
D.    The MAP propagates the radar event information to the RAP and the whole sector moves to the new channel.

Answer: A
The MAP performs the following steps as a response to radar detection:
1. The MAP sends a radar seen indication to the parent and ultimately to the RAP indicating that the channel is infected. The RAP sends this message to the controller. The message appears to be coming from the RAP. The MAP, RAP, and controller mark the channel as infected for 30 minutes.
2. The MAP blocks the channel for 30 minutes. This 30-minute period is called the nonoccupancy period.
3. The controller sends a TRAP, which indicates that the radar has been detected on the channel. The TRAP remains until the nonoccupancy period expires.
4. The MAP has 10 seconds to move away from the channel. This is called the channel move time, which is defined as the time for the system to clear the channel and is measured from the end of the radar burst to the end of the final transmission on the channel.
5. The MAP enters the quiet mode. In the quiet mode, the MAP stops data transmissions. Beacons are still generated and probe responses are still delivered. The quiet mode exists until the channel move time is over (10 seconds).
6. The controller picks up a new random channel and sends the channel to the RAP.
7. The RAP receives the new channel information and sends channel change frames (unicast, encrypted) to a MAP, and each MAP sends the same information to its lower children down the sector. Each mesh access point sends the channel change frames once every 100 msecs for a total of five times.
8. Each mesh access point tunes to the new channel and enters into the silent mode. During the silent mode, only the receiver is ON. There is no packet transmission. An AP keeps scanning the new channel for any radar presence for 60 seconds. This process is called the channel availability check (CAC). The MAP should not disconnect from the controller. The network should remain stable during this one-minute period.

DFS functionality allows a MAP that detects a radar signal to transmit that up to the RAP, which then acts as if it has experienced radar and moves the sector. This process is called the coordinated channel change. This functionally can be turned on or off on the controller.
The coordinated channel change is enabled by default.
