300-430 Question 1

Single answer

An organization has deployed a Cisco FlexConnect solution for its branch offices. During a WAN outage, users in one of the branch offices report issues with accessing local resources despite being connected to the wireless network. Upon investigation, it is observed that the SSID in use is not functioning as expected during the WAN downtime. What could be the cause of this issue?

A
The SSID is not configured for FlexConnect Local Switching.
B
The AP is not in connected mode with the controller.
C
The VLAN mappings for the SSID are not defined on the AP in FlexConnect mode.
D
The FlexConnect AP is not configured for standalone mode.

Show answer and explanation

Correct answer: A

Explanation

In a Cisco FlexConnect deployment, SSIDs that need to continue functioning during WAN outages must be configured for Local Switching. This allows the AP to locally switch the traffic instead of trying to send it to the controller over the WAN. If Local Switching is not enabled, the SSID traffic will fail during WAN downtime, leading to the issue described.

A. Correct.
If the SSID is not configured for FlexConnect Local Switching, traffic from the SSID will still attempt to traverse the WAN to the controller, causing issues during a WAN outage.
B. Incorrect.
APs in connected or standalone mode will continue to operate with their configuration; however, this is not directly related to the issue described.
C. Incorrect.
While VLAN mappings are crucial for FlexConnect Local Switching, their absence would not result in complete SSID failure but may cause incorrect VLAN tagging.
D. Incorrect.
FlexConnect APs do not need to be explicitly configured for standalone mode; they automatically switch to standalone mode during a WAN outage.

300-430 Question 2

Single answer

A university campus deploys FlexConnect access points in its remote buildings to maintain wireless connectivity during WAN link failures. However, during a recent WAN outage, students reported losing access to the internet, even though the local network was operational. What configuration step did the network administrator likely miss to ensure internet access in this scenario?

A
Enable FlexConnect Local Switching on the access points.
B
Enable VLAN-based central switching on the WLAN.
C
Configure a backup RADIUS server that is reachable locally.
D
Enable FlexConnect Local Authentication on the WLAN.

Show answer and explanation

Correct answer: D

Explanation

When deploying FlexConnect in remote sites, enabling Local Authentication is critical to ensure client devices can authenticate to the WLAN during WAN outages. If Local Authentication is not enabled, clients will lose connectivity even when Local Switching is configured, as the access point will still attempt to reach the controller for authentication. By enabling Local Authentication, the AP can authenticate clients locally, ensuring uninterrupted connectivity.

A. Incorrect.
FlexConnect Local Switching ensures traffic is switched locally at the access point rather than being tunneled back to the controller. This helps during WAN outages but does not address authentication, which is the issue in this scenario.
B. Incorrect.
VLAN-based central switching routes all traffic through the controller, which is not ideal for WAN outage scenarios. This option would not solve the problem described.
C. Incorrect.
While a backup RADIUS server can help with authentication in some cases, it would not necessarily resolve the issue unless it was specifically configured to handle local authentication requests.
D. Correct.
FlexConnect Local Authentication allows authentication to occur locally at the access point without requiring a connection to the central controller. This configuration is essential for maintaining client connectivity when the WAN link to the controller is down.

300-430 Question 3

Single answer

An organization has deployed FlexConnect in their branch offices to provide wireless connectivity. During the deployment, the network engineer configures FlexConnect Local Switching for the branch access points. Which of the following is a valid reason to enable FlexConnect Local Switching in this scenario?

A
To allow the branch office access points to authenticate clients locally without requiring the WAN link to the controller
B
To enable seamless roaming between branch office access points and the central office access points
C
To reduce WAN bandwidth usage by routing client data traffic directly to the local network at the branch office
D
To centralize all client traffic at the controller to simplify security policy enforcement

Show answer and explanation

Correct answer: C

Explanation

FlexConnect Local Switching is a feature that enables access points to locally switch client data traffic directly to the local network at the branch office rather than tunneling all traffic back to the controller over the WAN. This reduces WAN bandwidth usage and improves performance for branch office deployments. It is particularly useful in environments where WAN links are limited or where local data offloading is preferred.

A. Incorrect.
This is incorrect because FlexConnect Local Switching does not handle client authentication locally. While authentication can be locally cached under certain conditions, Local Switching specifically refers to how client data traffic is handled.
B. Incorrect.
This is incorrect because seamless roaming between branch and central office access points requires centralized control, not Local Switching.
C. Correct.
This is correct because FlexConnect Local Switching allows client data traffic to be bridged locally at the branch office, avoiding the need to send it back to the controller over the WAN, which reduces WAN bandwidth usage.
D. Incorrect.
This is incorrect because centralizing client traffic at the controller is the opposite of what FlexConnect Local Switching achieves. Local Switching is designed to offload client traffic to the local network.

300-430 Question 4

Single answer

A retail company has deployed Cisco FlexConnect-enabled access points (APs) at their branch locations to ensure continued wireless connectivity even in case of WAN failures. One of their requirements is to allow clients to authenticate locally during WAN outages. Which feature must be configured to meet this requirement?

A
FlexConnect Local Switching
B
FlexConnect Central Authentication
C
FlexConnect Local Authentication
D
FlexConnect Split Tunneling

Show answer and explanation

Correct answer: C

Explanation

FlexConnect Local Authentication is the correct feature to configure because it enables access points to authenticate clients locally in the absence of a WAN connection. This is critical in environments like retail branches where WAN failures would otherwise disrupt client connectivity and authentication. Other features, such as Local Switching, Central Authentication, and Split Tunneling, do not address the specific need for local client authentication during WAN outages.

A. Incorrect.
FlexConnect Local Switching allows the AP to locally switch traffic to the local VLAN at the branch site. While important in FlexConnect, this does not handle client authentication during WAN outages.
B. Incorrect.
FlexConnect Central Authentication requires the WAN connection to be active because authentication is performed by resources located at the central site. This does not meet the requirement of authenticating clients locally during WAN failures.
C. Correct.
FlexConnect Local Authentication allows the access point to authenticate clients locally using a cached RADIUS server configuration or a local RADIUS server. This meets the requirement of supporting client authentication during WAN outages.
D. Incorrect.
FlexConnect Split Tunneling enables traffic to be split between local and central paths based on specific policies, but it does not address client authentication during WAN outages.

300-430 Question 5

Single answer

A retail company is deploying Cisco FlexConnect in their branch locations to minimize WAN usage while maintaining connectivity to the centralized Wireless LAN Controller (WLC). During the design phase, the engineer is asked to ensure that wireless clients can continue to access local resources even if the WAN link to the WLC goes down. Which feature of FlexConnect should the engineer enable?

A
Local Switching
B
Central Authentication
C
FlexConnect ACLs
D
FlexConnect Grouping

Show answer and explanation

Correct answer: A

Explanation

FlexConnect's Local Switching feature is key to enabling wireless clients to access local resources without relying on the WAN link to the WLC. This is especially useful in branch deployments where WAN connectivity may be intermittent or unreliable. Central Authentication and other features do not address this requirement.

A. Correct.
Local Switching enables traffic from wireless clients to be locally switched at the access point, allowing them to access local resources even if the WAN link to the WLC is down.
B. Incorrect.
Central Authentication requires the WAN link to the WLC to authenticate clients, which would not work if the WAN link is unavailable.
C. Incorrect.
FlexConnect ACLs are used to control traffic at the access point level but do not ensure local resource access when the WAN link is down.
D. Incorrect.
FlexConnect Grouping is a management feature to configure multiple access points simultaneously but does not directly impact client connectivity to local resources.

300-430 Question 6

Single answer

An organization has deployed Cisco FlexConnect for their branch office wireless network. The branch office experiences WAN link failures occasionally, and the IT administrator wants to ensure that the wireless clients can continue accessing local resources during such outages. Which FlexConnect operating mode and switching mode combination should the administrator configure to meet this requirement?

A
Centralized switching with connected mode
B
Centralized switching with standalone mode
C
Local switching with connected mode
D
Local switching with standalone mode

Show answer and explanation

Correct answer: D

Explanation

FlexConnect operating modes (connected and standalone) determine whether the AP requires connectivity to the controller for operation. Switching modes (centralized and local) dictate whether client traffic is tunneled to the controller or switched locally. In this case, 'local switching' ensures client traffic remains within the branch office, and 'standalone mode' allows the AP to operate independently of the controller during WAN failures. Therefore, 'local switching with standalone mode' is the correct configuration.

A. Incorrect.
Centralized switching with connected mode requires the WAN link to be active because all client traffic is tunneled back to the central controller. This does not meet the requirement for continued access during WAN outages.
B. Incorrect.
Centralized switching with standalone mode is not a valid configuration since FlexConnect centralized switching relies on connectivity to the WAN and central controller.
C. Incorrect.
Local switching with connected mode allows traffic to be locally switched at the branch office, but the connected mode requires the WAN link to remain active for the controller to manage the APs.
D. Correct.
Local switching with standalone mode allows traffic to be locally switched at the branch office and enables the AP to continue functioning even during WAN failures, meeting the requirement.

300-430 Question 7

Single answer

An organization has deployed a Cisco wireless network using FlexConnect mode to support branch locations. The administrator wants to ensure that wireless clients can continue to access local resources even if the WAN link to the central office becomes unavailable. Which FlexConnect feature or configuration is required to achieve this?

A
Enable Local Switching on the FlexConnect APs.
B
Configure the APs to operate in Bridge Mode.
C
Enable OfficeExtend Mode on the APs.
D
Configure the APs to operate in Monitor Mode.

Show answer and explanation

Correct answer: A

Explanation

FlexConnect is designed to support deployments where branch sites have limited or unreliable WAN connectivity to the central controller. Enabling Local Switching on FlexConnect APs allows them to switch client traffic directly to the local network, ensuring uninterrupted access to local resources even if the WAN link to the central office becomes unavailable. This is a key feature of FlexConnect and is critical for ensuring network resilience in branch deployments.

A. Correct.
Enabling Local Switching on FlexConnect APs allows wireless traffic to be forwarded directly to the local network at the branch site without needing to traverse the WAN link to the central office. This ensures clients can access local resources even if the WAN link is down.
B. Incorrect.
Bridge Mode is not a FlexConnect-specific mode and is typically used for creating point-to-point or point-to-multipoint wireless links. It does not address the issue of local resource access in the event of WAN failure.
C. Incorrect.
OfficeExtend Mode is used to provide secure connectivity for teleworkers and is not related to enabling local resource access in a FlexConnect deployment.
D. Incorrect.
Monitor Mode is used for intrusion detection, site surveys, or troubleshooting, and does not enable local resource access or traffic forwarding in a FlexConnect environment.

300-430 Question 8

Select 2

A company is deploying a wireless network in a branch office using FlexConnect. They want the access points to locally switch traffic for certain SSIDs while maintaining central authentication. Additionally, they need the ability to operate independently of the WAN link to the central controller in case of link failure. Which FlexConnect deployment configuration should they use?

A
FlexConnect local switching with connected mode
B
FlexConnect local switching with standalone mode
C
FlexConnect central switching with connected mode
D
FlexConnect central switching with standalone mode

Show answer and explanation

Correct answers: A, B

Explanation

To meet the requirements of local traffic switching and the ability to operate independently during WAN link failure, the correct configuration is FlexConnect local switching with both connected and standalone modes. Local switching ensures that client traffic is routed locally at the site, while connected mode allows for central authentication when the WAN link is active. Standalone mode ensures continuity of service in the event of a WAN failure.

A. Correct.
This option is correct because FlexConnect local switching allows the access point to switch traffic locally at the site, and connected mode ensures that the AP is in communication with the controller for central authentication when the WAN link is active.
B. Correct.
This option is correct because standalone mode allows the access point to operate independently of the WAN link and the controller, ensuring continued operation during link failure.
C. Incorrect.
This option is incorrect because central switching requires all client traffic to tunnel back to the controller, which does not meet the requirement for local traffic switching.
D. Incorrect.
This option is incorrect because central switching with standalone mode is not a supported configuration in FlexConnect, as central switching inherently requires connectivity to the controller.

300-430 Question 9

Single answer

Which configuration ensures that wireless clients can continue to access local resources, such as printers, even when the WAN link is down?

A
Configure the access points in FlexConnect local switching mode
B
Enable central authentication on the access points
C
Deploy the access points in FlexConnect central switching mode
D
Enable VLAN-based central authentication and switching

Show answer and explanation

Correct answer: A

Explanation

FlexConnect local switching mode is designed to handle scenarios where access points at a remote site need to operate independently of the controller due to WAN link issues. By switching client traffic locally, FlexConnect ensures uninterrupted access to local resources like printers and servers, even when the central controller is unavailable.

A. Correct.
Correct: FlexConnect local switching mode allows access points to switch traffic locally at the site, enabling clients to access local resources even when the WAN link is unavailable.
B. Incorrect.
Incorrect: Central authentication requires a connection to the central controller, which is not feasible when the WAN link is down.
C. Incorrect.
Incorrect: Central switching mode sends all client traffic to the central controller, which would fail if the WAN link is unstable or down.
D. Incorrect.
Incorrect: VLAN-based central authentication and switching still depends on the central controller, which cannot be reached during WAN outages.

300-430 Question 10

Single answer

A company is deploying a branch office using Cisco FlexConnect to minimize traffic backhauling to the central data center. The branch office has a wireless network with both local and central resources. Which FlexConnect configuration ensures local traffic, such as file sharing between branch users, is handled locally, while critical traffic, such as guest authentication, is sent to the central controller for processing?

A
FlexConnect Local Switching with Central Authentication
B
FlexConnect Central Switching with Local Authentication
C
FlexConnect Local Switching with Local Authentication
D
FlexConnect Central Switching with Central Authentication

Show answer and explanation

Correct answer: A

Explanation

FlexConnect Local Switching with Central Authentication is the correct choice for this scenario because it allows local traffic to be handled at the branch office, reducing dependency on the central controller, while ensuring that critical traffic, such as guest authentication, is sent to the central controller for processing. This configuration balances the need for local autonomy and central management.

A. Correct.
FlexConnect Local Switching with Central Authentication allows local traffic, such as file sharing, to be switched locally at the branch, while critical traffic, such as guest authentication, is sent to the central controller for processing. This is the appropriate configuration for the scenario.
B. Incorrect.
FlexConnect Central Switching with Local Authentication sends all traffic, including local traffic, to the central controller for switching, which does not optimize local traffic handling at the branch office.
C. Incorrect.
FlexConnect Local Switching with Local Authentication processes both local traffic and authentication at the branch, which does not meet the requirement of sending critical traffic, such as guest authentication, to the central controller.
D. Incorrect.
FlexConnect Central Switching with Central Authentication sends both traffic and authentication to the central controller, which negates the benefits of minimizing traffic backhauling in this scenario.
