A customer has two Cisco 550B WLCs that manage all the access points in their network and provide N+1 redundancy and load balancing. The primary Cisco WLC has 60 licenses and the secondary Cisco WLC has 40. The customer wants to convert the N+1 model to an HA model and provide SSO.
Configuration must be performed during a maintenance window. After performing all the configurations on both controllers, the config redundancy unit secondary command is issued on the secondary Cisco WLC and it fails.
Which parameter needs to be in place to complete the configuration?
- A . A cable in the RP port
- B . The secondary Cisco WLC needs a minimum of 50 base licenses
- C . The primary Cisco WLC is already set as the secondary unit.
- D . SSO needs to be enabled
An engineer at a global enterprise organization must ensure that a mesh deployment has the highest number of channels available to the backhaul, regardless of region deployed, which design meets this requirement?
- A . one controller per continent
- B . one controller per country code
- C . redundant controllers in the most restrictive regulatory domain
- D . redundant controllers in the least restrictive regulatory domain
A customer celled with a requirement that internal clients must be on different subnets depending on the building they are in, AH access points are operating in local mode and will not be modified, and this is a single controller solution.
Which design approach creates the desired result?
- A . Create an SSID, place it to the desired VLAN under WLANs, and configure 802 lx in ISE to assign the correct VLAN based on the SSID from which the client is authenticating.
- B . Create FlexConnecI groups, place the access points in. and sat the correct VLAN to SSID mapping based on location.
- C . Create AP groups for each desired location, map the correct VLANs to the internal SSID, and add the access points for that location.
- D . Create mobility anchors for the SSID, and on the controller under the internal SSID. create a foreign map to the desired VLAN based on location.
A high-density wireless network is designed.
Which Cisco WLC configuration setting must be incorporated in the design to encourage clients to use the 5 GHz spectrum?
- A . RRM
- B . Cisco centralized key management
- C . Band select
- D . Load balancing
An engineer changed the TPC Power Threshold for a wireless deployment from the default value to – 65 dBm. The engineer conducts a new post-deployment Survey to validate the results.
What is the expected outcome?
- A . Increase cell size
- B . Decreased client signal strength
- C . Increased received sensitivity
- D . Decreased channel overlap
A network engineer is working on a predictive WLAN design, the new wireless network must support access to Internet, email, voice, and the inventory database, to successfully support these services.
Which configuration must the engineer use for the signal strength levels and SNR on the planning tool?
- A . signal strength of -67 dBm, 25-dB SNR, and maximum 1 percent packet loss.
- B . signal strength of -67 dBm, 20-dB SNR, and maximum 5 percent, packet loss.
- C . signal strength of 67 dBm, 20-dB SNR, and maximum 1 percent packet loss.
- D . signal strength of-70 dBm,30-dB SNR. and maximum 10 percent packet loss.
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 Yagi antenna
- B . AP with a patch antenna
- C . AP with a monopole antenna
- D . AP with an integrated antenna
- E . AP with a dipole antenna
An engineer must perform an assessment of a customer LAN for a future IEEE 802.11ac Wave 2 wireless deployment All access switches are Fast Ethernet-Capable only, and the wired infrastructure between existing APs and access switches is based on the CAT 6A standard.
Which two actions provide maximum support of Cisco 3800 Series access points? (Choose two.)
- A . Replace the existing switches with mGig switches.
- B . Replace the existing switches with gigabit switches with 10G uplinks.
- C . Ensure that cable distances between access switches and APs are not longer than 100 meters.
- D . Replace the existing wiring infrastructure with the CAT-7E wiring standard,
- E . Ensure that cable distances between access switches and APs are not longer than 55 meters.
An engineer as performing a Layer 1 passive wireless site survey utilizing a channel analyzer software in the 2.4 GHz spectrum.
Which chart indicates the ratio of interference present during the duration of the capture?
A)
B)
C)
- A . Option A
- B . Option B
- C . Option C
- D . Option D
During a post-deployment site Survey, issues are found with non wi-Fi interference.
What should the engineer use to identify the source of the Interference?
- A . Network analysis module
- B . Wireless intrusion prevention
- C . Wireshark
- D . Cisco spectrum expert
