Cisco CCNP Enterprise 300-430 Questions & Answers

• Question 151:

  A company has a single WLAN configured for 802.1x authentication with the QoS set to Silver. This WLAN supports all corporate and BYOD access. A decision has been made to allow users to install Cisco Jabber on their personal mobile devices. Users report poor voice quality when using Jabber.

  QoS is being applied only as best effort. What must be configured to ensure that the WLAN remains on the Silver class and to ensure Platinum class for Jabber?

  A. Configure an AVC profile for the Jabber traffic and apply it to the WLAN.

  B. Configure the WLAN to broadcast on 5 GHz radios only and allow Jabber users to conned.

  C. Enable Cisco Centralized Key Management on the WLAN so that the Jabber-enabled devices will connect.

  D. Configure QoS on the mobile devices that have Jabber installed.

  Correct Answer: A

• Question 152:

  An engineer must implement intrusion protection the WLAN. The AP coverage is adequate and on- channel attacks are the primary concern. The building is historic, which makes adding APs difficult. Which Ap mode and submode must be implemented?

  A. Ap mode: local, Ap submode: WIPS

  B. Ap mode: monitor, Ap submode: WIPS

  C. Ap mode: monitor, Ap submode: none

  D. Ap mode: local, Ap submode: none

  Correct Answer: A

  the on-channel says no need to scan other channels.

• Question 153:

  A network engineer has been hired to perform a new MSE implementation on an existing network. The MSE must be installed in a different network than the Cisco WLC. Which configuration allows the devices to communicate over NMSP?

  A. Allow UDP/16113portonthe central switch.

  B. Allow TCP/16666 port on the router.

  C. Allow TCP/16113 port on the firewall.

  D. Allow UDP/16666 port on the VPN router.

• Question 154:

  A corporation has a wireless network where all access points are configured in FlexConnect. The WLC has a Data WLAN and a VoWiFi WLAN implemented where centrally-switched is configured for the APs. Which QoS configuration must be implemented for the wireless packets to maintain the marking across the wired and wireless network?

  A. Enable CAC

  B. Trust DSCP

  C. Set QoS to Platinum

  D. Allow WMM

  Correct Answer: B

  WMM is WiFi Multimedia Qos, the question was which feature provides for wireless and WIRED

• Question 155:

  An engineer must track guest traffic flow using the WLAN infrastructure. Which Cisco CMX feature must be configured and used to accomplish this tracking?

  A. analytics

  B. connect and engage

  C. presence

  D. detect and locate.

  Correct Answer: C

  The Cisco CMX Presence Analytics service is a comprehensive analytics and engagement platform that uses APs to detect visitor presence based on their mobile devices' Received Signal Strength Indication (RSSI). The AP detects these client mobile devices irrespective of the latter's wireless association state as long as they are within the specified signal range, and the wireless option is enabled on the mobile device (ability to detect devices wirelessly even if they are not connected to the network https://www.cisco.com/c/en/us/td/docs/wireless/mse/10- 4/cmx_config/b_cg_cmx104/the_cisco_cmx_presence_analytics_service.html

• Question 156:

  What is configured to use more than one port on the OEAP to extend the wired network's?

  A. AAA override

  B. client load balancing

  C. remote LAN ACL

  D. remote LAN

  Correct Answer: D

• Question 157:

  Which configured is applied to prevent the network from a Layer 2 flooding of multicast frames with a seamless transfer of multicast data to the client when roaming from one controller to another?

  A. Enable IGMPv3 on the central Layer 3 switch.

  B. Enable IGMP snooping on the WLC

  C. Enable multicast mode on the WLC

  D. Create multicast groups on the central Layer 3 switch.

  Correct Answer: B

• Question 158:

  When configuring a Cisco WLC, which CLI command adds a VLAN with VLAN ID of 30 to a FlexConnect group named BranchA-FCG?

  A. config flexconnect BranchA-FCG vlan 30 add

  B. config flexconnect group BranchA-FCG vlan add 30

  C. config flexconnect group BranchA-FCG vlan 30 add

  D. config flexconnect BranchA-FCG vlan add 30

  Correct Answer: B

• Question 159:

  Which two configurations are applied on the WLC to enable multicast, check multicast stream subscriptions, and stream content only to subscribed clients? (Choose two)

  A. Enable IGMP snooping

  B. Set the IGMP timeout to 180 seconds

  C. Enable broadcast forwarding

  D. Enable 802.3x flow control mode.

  E. Set the AP multicast to 238.255.255.255

  Correct Answer: AC

• Question 160:

  Refer to the exhibit.

  

  An engineer tries to manage the rogues on the Cisco WLC. Based on the configuration, which AP is marked as malicious by the controller?

  A. rogue AP with SSID admin seen for 4000 seconds and heard at -70dBm

  B. rogue AP with SSID admin seen for 3000 seconds and heard at -60dBm

  C. rogue AP with SSID admin seen for 4000 seconds and heard at -60dBm

  D. rogue AP with SSID admin seen for 3000 seconds and heard at -70dBm

  Correct Answer: C

  Duration - Requires that the rogue access point be detected for a minimum period of time (everything greater than that triggers the rule - 4000 is more than 3600). RSSI - Requires that the rogue access point have a minimum RSSI value (everything greater than that triggers the rule - -60dBm is greater signal power than -65dBm)
