13、A customer called with a requirement that internal clients must be on different subnets depending on the building they are in All 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?

Create AP groups for each desired location, map the correct VLANs to the internal SSlD and add the access prints for that location

Create an SSID. place it to the desired VLAN under WLANs. and configure 802.ix in ISE to assign the correct VLAN based on the SSlD from which the client is authenticating.

Create FiexConnect groups, place the access points in. and set the correct VLAN to SSlD mapping based on location.

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

14、Which common issue causes intermittent DMVPN tunnel flaps?

a routing neighbor reachability issue

a suboptimal routing table

interface bandwidth congestion

that the GRE tunnel to hub router is not encrypted

DMVPN Tunnel Flaps Intermittently
Problem
DMVPN tunnel flaps intermittently.
Solution
When DMVPN tunnels flap, check the neighborship between the routers as issues with neighborship formation between routers may cause the DMVPN tunnel to flap. In order to resolve this problem, make sure the neighborship between the routers is always up.

15、A network administrator of a global organization is collapsing all controllers to a single cluster located in central Europe. Which concern must addressed?

Some channels may not be available consistently across the organization.

Different RF policies per office are not available in this configuration.

Syslog must be configured to the time-zone of the NMS platform.

Centralized controllers cannot uniformly authenticate global users.

16、An engineer is reducing the subnet size of the corporate WLAN by segmenting the VLAN into smaller subnets. Clients will be assigned a subnet by location. Which type of groups can the engineer use to map the smaller subnets to the corporate WLAN?

WLC port groups

RF groups

AP groups

interface groups

17、How does AP failover priority for access points function when configured with priority 1 or 4?

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.

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.

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.

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.

18、Which statement about creating a mobility group is true, excluding mobility anchors?

Each WLC must use the same mobility domain name and be defined as a peer in each other’s static mobility members list.

If WLCs with HA SSO are deployed, each WLC in the WLC HA pair is considered separately as a mobility peer.

The WLCs do not have to be of the same model or type to be a member of a mobility group, however each member should be running different software versions.

A mobility group does not require all WLCs in the group to use the same virtual IP address.

Section: Mobility

19、An engineer must ensure that the new wireless LAN deployment can support seamless roaming between access points using a standard based on an amendment to the 802.11 protocol. Which protocol must the engineer selects?

802.11i

802.11ac

802.11r

802.11e

20、A wireless engineer is designing a wireless network to support real-time applications over wireless. Which IEEE protocol must the engineer enables on the WLC so that the number of packets that are exchanged between an access point and client are reduced and fast roaming occurs?

802.11w

802.11r

802.11i

802.11k

21、An engineer has configured guest anchoring for a newly created SSD however, the mobility tunnels are not up, and EPING is failing from the foreign WLC to the anchor WLC. Which traffic flow must be allowed at the firewall to enable the communication?

UDP port 16666

IP protocol 97

UDP port 97

TCP port 97

22、A wireless engineer is designing a wireless network to support real-time applications over wireless. Which IEEE protocol must the engineer enable on the WLC so that the number of packets that are exchanged between an access point and client are reduced and fast roaming occurs?

802.11w

802.11r

802.11i

802.11k

Section: Wired and Wireless Infrastructure

23、A network engineer is configuring high availability on an access point. What is the maximum number of controllers that can be configured?

So max 2 will be supported on an AP.

24、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 rule is needed at the firewall to allow UDP port 16666 for communication to work.

A rule is needed at the firewall to allow UDP port 97 for communication to work.

A rule is needed at the firewall to allow TCP port 97 for communication to work.

A rule is needed at the firewall to allow TCP port 16666 for communication to work.

25、An engineer must perform a pre deployment site survey For a new building in a high-security area The design must provide a primary signal RSSI of -65 dBM for the clients Which two requirements complete this design? (Choose two)

site access

AP model

WLC model

HVAC access

number of clients

26、A rapidly expanding company has tasked their network engineer with wirelessly connecting a new cubicle area with Cisco workgroup bridges until the wired network is complete. Each of 42 new users has a computer and VoIP phone. How many APs for workgroup bridging must be ordered to keep cost at a minimum while connecting all devices?

So, each AP will have 25 clients. Minimum 4 APs are sufficient.

27、An engineer must create data link redundancy for the company’s Cisco Wireless LAN controller. The engineer has decided to configure LAG-based redundancy instead of port-based redundancy. Which three features of LAG-based redundancy influenced this decision? (Choose three.)

Packets are always sent out on the same port they are received on.

All interface traffic passes as long as one port is up.

The same port has multiple untagged dynamic interfaces.

Interface connection to two separate nonstacked switches is available.

Full bandwidth of all links is available.

Ports are grouped into multiple LAGs.
