When using a Cisco Catalyst 9800 Series Wireless Controller, which statement about
AutoQoS is true?

A.

It has a set of predefined profiles that you cannot modify further

B.

It matches traffic and assigns each matched packet to QoS groups

C.

It automates deployment of wired QoS and makes wireless QoS implementation easier

D.

It allows the output policy map to put specific QoS queues into specific subgroups

Which command set configures a Cisco Catalyst 9800 Series Wireless Controller so that
the client traffic enters the network at the AP switch port?

A. Option A

B. Option B

C. Option C

D. Option D

An engineer is implementing Cisco Identity-Based Networking on a Cisco AireOS
controller. The engineer has two ACLs on the controller. The first ACL, named BASE_ACL,
is applied to the corporate_clients interface on the WLC, which is used for all corporate
clients. The second ACL, named HR_ACL, is referenced by ISE in the Human Resources
group policy. What is the resulting ACL when a Human Resources user connects?

A.

HR_ACL appended with BASE_ACL

B.

HR_ACL only

C.

BASE_ACL appended with HR_ACL

D.

BASE_ACL only

All APs are receiving multicast traffic, instead of only the APs that need it. What is the
cause of this problem?

A.

The multicast group includes all APs

B.

The wrong multicast address was used

C.

The multicast group is assigned the wrong VLAN

D.

Multicast IGMP snooping is not enabled

An engineer is performing a Cisco Hyperlocation accuracy test and executes the cmxloc
start command on Cisco CMX. Which two parameters are relevant? (Choose two.)

A.

X, Y real location

B.

client description

C.

AP name

D.

client MAC address

E.

WLC IP address

An engineer must use Cisco AVC on a Cisco WLC to prioritize Cisco IP cameras that use
the wireless network. Which element do you configure in a rule?

A.

permit-ACL

B.

WMM required

C.

mark

D.

rate-limit

Which two restrictions are in place with regards to configuring mDNS? (Choose two.)

A.

mDNS uses only UDP port 5436 as a destination port.

B.

mDNS cannot use UDP port 5353 as the destination port.

C.

mDNS is not supported on FlexConnect APs with a locally switched WLAN.

D.

Controller software must be newer than 7.0.6+.

E.

mDNS is not supported over IPv6.

Which statement about the VideoStream/Multicast Direct feature is true?

A.

IP multicast traffic is reliable over WLAN by default as defined by the IEEE 802.11
wireless multicast delivery mechanism.

B.

Each VideoStream client acknowledges receiving a video IP multicast stream.

C.

It converts the unicast frame to a multicast frame over the air.

D.

It makes the delivery of the IP multicast stream less reliable over the air, but reliable
over Ethernet.

An engineer is configuring multicast for two WLCs. The controllers are in different physical locations and each handles around 500 wireless clients. How should the CAPWAP multicast group address be assigned during configuration?

A. Each WLC must be assigned a unique multicast group address.

B. Each WLC management address must be in the same multicast group.

C. Both WLCs must be assigned the same multicast group address.

D. Each WLC management address must be in a different multicast group.

An engineer is troubleshooting a Cisco CMX high-availability deployment and notices that the primary and backup Cisco CMX servers are both considered primary. Which command must the engineer run on the backup server?

A. cmxha convert backup

B. cmxha backup convert

C. cmxha secondary convert

D. cmxha convert secondary

An engineer implemented AP Authorization with Cisco ISE utilizing AP MAC addresses as local users in Cisco ISE. Everything has been working fine until recently. It has been noticed that APs that reboot are temporarily disconnected from the network and cannot rejoin the controller. Which action completes the implementation?

A. Remove APs from the exclusion list, due to authentication failures.

B. Disable the Cisco ISE password policy that disables accounts for unchanged passwords.

C. Install a valid EAP certificate on Cisco ISE for the APs.

D. Upgrade Cisco ISE to a newer version due to bugs.

An engineer is deploying a virtual MSE. The network has 3000 APs and needs 7000 IPS licenses. To which size server does the engineer scale it?

A. virtual

B. standard

C. high end

D. low end
