Question 3

An engineer must implement Cisco Identity-Based Networking Services at a remote site using ISE to dynamically assign groups of users to specific IP subnets. If the subnet assigned to a client is available at the remote site, then traffic must be offloaded locally, and subnets are unavailable at the remote site must be tunneled back to the WLC. Which feature meets these requirements?

Accepted Answer

VLAN-based central switching allows for local offloading of traffic when the subnet is available at the remote site, and it can tunnel traffic back to the WLC when the subnet is unavailable.

Question 5

An organization is supporting remote workers in different locations. In order to provide wireless network connectivity and services, OfficeExtend has been implemented. The wireless connectivity is working, but users report losing connectivity to their local network printers. Which solution must be used to address this issue?

Accepted Answer

OEAP split tunnel allows traffic destined for the local network, such as local network printers, to bypass the tunnel back to the corporate network, thus maintaining connectivity to local resources.

Question 6

Branch wireless users report that they can no longer access services from head office but can access services locally at the site. New wireless users can associate to the wireless while the WAN is down. Which three elements (Cisco FlexConnect state, operation mode, and authentication method) are seen in this scenario? (Choose three.)

Accepted Answer

The answer of Branch wireless users report that they can...

Question 7

An engineer must configure MSE to provide guests access using social media authentication. Which service does the engineer configure so that guests use Facebook credentials to authenticate?

Accepted Answer

Social Connect is the service that allows guests to authenticate using social media credentials like Facebook.

Question 8

Which two steps are needed to complete integration of the MSE to Cisco Prime Infrastructure and be able to track the location of clients/rogues on maps? (Choose two.)

Accepted Answer

The answer of Which two steps are needed to complete...

Question 9

A network engineer observes a spike in controller CPU overhead and overall network utilization after multicast is enabled on a controller with 500 APs. Which feature corrects the issue?

Accepted Answer

The answer of A network engineer observes a spike in...

Question 10

An engineer is implementing a FlexConnect group for access points at a remote location using local switching but central DHCP. Which client feature becomes available only if this configuration is changed?

Accepted Answer

The answer of An engineer is implementing a FlexConnect group...

Question 11

A wireless engineer needs to implement client tracking. Which method does the angle of arrival use to determine the location of a wireless device?

Accepted Answer

The angle of arrival method determines the location of a wireless device by measuring the angle at which signals arrive at the receiving antenna, which is referred to as the angle of incidence.

Question 12

A network engineer is deploying 8865 IP phones with wireless clients connected to them. In order to apply the appropriate QoS, the IP voice traffic needs to be distinguished from client data traffic. Which switch configuration feature must be enabled?

Accepted Answer

The Voice VLAN feature allows the switch to distinguish between voice traffic from IP phones and data traffic from connected clients, enabling appropriate QoS policies to be applied.

Question 13

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

Accepted Answer

Remote LAN is configured to use more than one port on the OEAP to extend the wired network, allowing multiple devices to connect through the OEAP.

Question 14

An engineer has been hired to implement a way for users to stream video content without having issues on the wireless network. To accomplish this goal, the engineer must set up a reliable way for a Media Stream to work between Cisco FlexConnect APs. Which feature must be enabled to guarantee delivery?

Accepted Answer

Multicast-to-Unicast Direct is used in Cisco FlexConnect to convert multicast traffic to unicast, ensuring reliable delivery over wireless networks.

Question 15

A corporation is spread across different countries and uses MPLS to connect the offices. The senior management wants to utilize the wireless network for all the employees. To ensure strong connectivity and minimize delays, an engineer needs to control the amount of traffic that is traversing between the APs and the central WLC. Which configuration should be used to accomplish this goal?

Accepted Answer

FlexConnect mode with local authentication allows the APs to handle client authentication locally, reducing the traffic between the APs and the central WLC, thus minimizing delays and ensuring strong connectivity.

Question 16

What is the difference between PIM sparse mode and PIM dense mode?

Accepted Answer

Sparse mode uses distribution trees to efficiently route multicast traffic only to interested receivers, while dense mode floods multicast traffic to all parts of the network and then prunes back unwanted traffic.

Question 17

A company is collecting the requirements for an on-premises event. During the event, a wireless client connected to a dedicated WLAN will run a video application that will need on average 391595179 bits per second to function properly. What is the QoS marking that needs to be applied to that WLAN?

Accepted Answer

The answer of A company is collecting the requirements for...

Question 18

When implementing self-registration for guest/BYOD devices, what happens when an employee tries to connect four devices to the network at the same time?

Accepted Answer

The answer of When implementing self-registration for guest/BYOD devices, what...

Question 19

The Cisco Hyperlocation detection threshold is currently set to -50 dBm. After reviewing the wireless user location, discrepancies have been noticed. To improve the Cisco Hyperlocation accuracy, an engineer attempts to change the detection threshold to -100 dBm. However, the Cisco Catalyst 9800 Series Wireless Controller does not allow this change to be applied. What actions should be taken to resolve this issue?

Accepted Answer

The Cisco Hyperlocation detection threshold cannot be changed while it is enabled. Disabling it first allows the threshold to be adjusted before re-enabling it.

Question 20

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?

Accepted Answer

The Network Mobility Services Protocol (NMSP) uses TCP port 16113 for communication between the Cisco Wireless LAN Controller (WLC) and the Mobility Services Engine (MSE). Therefore, allowing TCP/16113 on the firewall will enable the necessary communication.
