A network engineer is working on a design for a wireless network that must support data, voice, and location services. To support these services, which access point placement must the engineer use?

A.

corner only

B.

perimeter and corner

C.

perimeter only

D.

indoor and outdoor

Which non-Wi-Fi interferer can be identified by Metageek Chanalyzer?

A.

A customer has two Cisco wireless controllers named WLC-A and WLC-B. Each controller is in a different building on a campus. The WLCs have different Layer 3 interfaces and broadcast the same SSIDs from their respective APs. Users must remain connected to the same VLAN and

maintain their IP addresses during roaming from the APs that are attached to WLC-A and WLC B. Which action accomplishes the requirement?

A.

Create a mobility group between the two WLCs to allow auto-anchoring.

B.

Create an SSO cluster to ensure that client sessions sync between WLCs.

C.

Enable 802.11r on each SSID on both WLCs to allow caching of the PMK.

D.

Enable AP groups using the same name on both WLCs for each group.

When conducting a site survey for real-time traffic over wireless, which two design capabilities of smartphones and tablets must be considered? (Choose two.)

A.

no support for 802.11ac

B.

higher data rates than laptops

C.

fewer antennas than laptops

D.

no support for 802.11r

E.

lower data rates than laptops

A customer is running a guest WLAN with a foreign/export-anchor setup. There is one anchor WLC in the US and two in Europe. Anchor WLC priorities are used to prefer local anchors. During a routine network audit, it is discovered that a large number of guest client sessions in the US are anchored to the WLCs in Europe. Which

reason explains this behavior?

A.

The foreign WLC failed and recovered.

B.

The US anchor WLC failed and recovered.

C.

The US anchor WLC is anchored to itself with a priority value of zero.

D.

The anchor WLC is in the same mobility group.

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.

Band Select

B.

RRM

C.

Cisco Centralized Key Management

D.

load balancing

Which feature must be incorporated into the network design to allow seamless Layer 3 roaming between controllers?

A.

Same VLANs across controllers

B.

Mobility groups

C.

Client load balancing

D.

Link aggregation

A customer deploys a new Cisco high-density wireless network within the open areas of a mall to provide free public wireless on 5 GHz. The existing mall tenants have their own wireless networks that are independently managed. Which design approach minimizes channel

utilization for the public network?

A.

Enable all 5-GHz channels that are supported by the region and use 40-MHz channels.

B.

Enable UNII-1 channels only and use 80-MHz channels.

C.

Enable UNII-1 channels only and use 20-MHz channels.

D.

Enable all 5-GHz channels that are supported by the region and use 20-MHz channels.

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 hospital has a Cisco Catalyst 9800 Series Wireless Controller in a SSO solution deployed to the primary data center The hospital plans to increase redundancy in the wireless environment Management decides to deploy an extra Catalyst 9800 WLC offsite to another data center on a different subnet. A WAN link connects the data centers with a firewall at both ends. Which two design approaches must the engineer take to ensure that the APs can fail over? (Choose two)

A.

Create a mobility tunnel between the wireless controllers.

B.

Open HTTPS port 443 between the wireless controllers.

C.

Create a static RF group leader on one of the wireless controllers.

D.

Open UDP ports 16666 and 16667 between the wireless controllers.

E.

Create a mobility group with the same names on both wireless controllers.
