You must ensure the HPEAruba network you are configuring for a client is capable of plug-and-play provisioning of access points. What enables this capability?

• A. UCC Service
• B. SRTP
• C. LLDP-MED
• D. CSMA

Answer: A

Explanation:
The capability that enables plug-and-play provisioning of access points in an HPE Aruba network is the UCC Service. The UCC Service is a cloud-based service that allows the access points to automatically discover and connect to the Aruba Central management platform without any manual intervention. The UCC Service also provides zero-touch configuration, firmware updates, and monitoring for the access points1.
The other options are incorrect because:
B) LLDP-MED: LLDP-MED is a protocol that enhances the interoperability between network devices and IP phones. It does not enable plug-and-play provisioning of access points2.
C) SRTP: SRTP is a protocol that provides encryption and authentication for voice and video traffic. It does not enable plug-and-play provisioning of access points3.
D) CSMA: CSMA is a protocol that regulates how devices share a common medium, such as a wireless channel. It does not enable plug-and-play provisioning of access points.

NEW QUESTION # 45
Review the exhibit.

You are troubleshooting an issue with a 10 102.39 0/24 subnet which is also VLAN 1000 used Tor wireless clients on a pair of Aruba CX 8360 switches The subnet SVI is configured on the 8360 pair, and the DHCP server is a Microsoft Windows Server 2022 Standard with an IP address of 10 200 1.100. The 10.102.250.0/24 subnet is used for switch management.
A large number of DHCP requests are failing You are observing sporadic DHCP behavior across clients attached to the CX 6100 switch.
Which action may help fix the issue?

• A.
• B.
• C.
• D.

Answer: C

Explanation:
Explanation
Option C is the only action that configures the DHCP relay on the SVI of VLAN 1000 on the CX 8360 switches. DHCP relay is a feature that allows a switch to forward DHCP requests from clients in one subnet to a DHCP server in another subnet. DHCP relay is required when the DHCP server and the clients are not in the same broadcast domain1.
Option C uses the following commands:
interface vlan 1000: This command enters the interface configuration mode for the SVI of VLAN 1000, which has an IP address of 10.102.39.1/24 and is used for wireless clients.
ip helper-address vrf default 10.200.1.100: This command configures the IP address of the DHCP server as a helper address for the SVI, which means that the switch will forward DHCP requests from clients on VLAN 1000 to this address. The vrf default parameter indicates that the SVI and the DHCP server are in the same VRF.

NEW QUESTION # 46
Refer to the exhibit.

A company has deployed 200 AP-635 access points. To but is not working as expected What would be the correct action to fix the issue?

• A. Change the SSID to WPA3-Enhanced Open
• B. Change the SSID to WPA3-Personal
• C. Change the SSID to WPA3-Enterprise (CCM).
• D. Change the SSID to WPA3-Enterpnse (CNSA).

Answer: D

Explanation:
Explanation
According to the Aruba Campus Access Professional documents1, WPA3-Enterprise is a security mode that supports 802.1X authentication and encryption with either AES-CCM or AES-GCMP. WPA3-Enterprise also optionally adds usage of Suite-B 192-bit minimum-level security suite that is aligned with Commercial National Security Algorithm (CNSA) for enterprise networks2. This mode provides the highest level of security and is suitable for government and financial institutions.
The exhibit shows that the SSID is configured with WPA3-Enterprise (CCM), which uses AES-CCM as the encryption protocol. However, this mode is not compatible with some devices that require CNSA compliance.
Therefore, changing the SSID to WPA3-Enterprise (CNSA) would fix the issue and allow all devices to connect to the network.

NEW QUESTION # 48
Refer to the image.

Your customer is complaining of weak Wi-Fi coverage in their office. They mention that the office on the other side of the hall has much better signal What is the likely cause of this issue7

• A. The AP is configured in Mesh mode
• B. The AP is a remote access point.
• C. The AP is using a directional antenna.
• D. The AP is an outdoor access point.

Answer: C

Explanation:
Explanation
The likely cause of the issue of weak Wi-Fi coverage in the office is that the AP is using a directional antenna.
A directional antenna is an antenna that radiates or receives radio waves more strongly in one or more directions, creating a focused beam of signal. A directional antenna can provide better coverage and performance for a specific area, but it can also create dead zones or weak spots for other areas. The other options are incorrect because they either do not affect the Wi-Fi coverage or do not match the scenario.

NEW QUESTION # 49
Which feature allows the device to remain operational when a remote link failure occurs between a Gateway cluster and a RADIUS server that is either in the cloud or a datacenter?

• A. MAC Authentication
• B. MAC caching
• C. Authentication survivability
• D. Opportunistic key caching

Answer: C

Explanation:
Explanation
Authentication survivability is a feature that allows the device to remain operational when a remote link failure occurs between a Gateway cluster and a RADIUS server that is either in the cloud or a datacenter.
Authentication survivability enables the Gateway cluster to cache successful authentication requests from the RADIUS server and use them to authenticate clients when the RADIUS server is unreachable. Authentication survivability also allows clients to use MAC caching or MAC authentication bypass (MAB) methods to access the network when the RADIUS server is down. References:

NEW QUESTION # 50
A customer is using stacked Aruba CX 6200 and CX 6300 switches for access and a VSX pair of Aruba CX 8325 as a collapsed core 802 1X is implemented for authentication. Due to the lack of cabling, some unmanaged switches are still in use Sometimes devices behind these switches cause network outages The switch should send a warning to the helpdesk when the problem occurs You have been asked to implement an effective solution to the problem What is the solution for this?

• A. Configure loop protection on all edge ports of the Aruba CX 6200 and CX 6300 switches No trap option is needed
• B. Configure spanning tree on the Aruba CX 8325 switches Set the trap-option
• C. Configure loop protection on all edge ports of the Aruba CX 6200 and CX 6300 switches Set up the trap-option
• D. Configure spanning tree on the Aruba CX 6200 and CX 6300 switches No trap option is needed

Answer: C

Explanation:
This is the correct solution to the problem of devices behind unmanaged switches causing network outages due to loops. Loop protection is a feature that allows an Aruba CX switch to detect and prevent loops by sending loop protection packets on each port, LAG, or VLAN on which loop protection is enabled. If a loop protection packet is received by the same switch that sent it, it indicates a loop exists and an action is taken based on the configuration. Loop protection should be configured on all edge ports of the Aruba CX 6200 and CX 6300 switches, which are the ports that connect to end devices or unmanaged switches. The trap-option should be set up to send a warning to the helpdesk when a loop is detected. The other options are incorrect because they either do not configure loop protection or do not set up the trap-option.

NEW QUESTION # 51
What is an Aruba-recommended best practice for hardening that only applies to Aruba CX 6300 series switches with dedicated management ports?

• A. Manually enable Enhanced Security Mode from a console session.
• B. Implement a control plane ACL to limit access to approved IPs and/or subnets
• C. Disable all management services on the default VRF.
• D. Create a dedicated management VRF, and assign the management port to it.

Answer: D

Explanation:
This is an Aruba-recommended best practice for hardening that only applies to Aruba CX 6300 series switches with dedicated management ports. A dedicated management port is a physical port that is used exclusively for out-of-band management access to the switch. A dedicated management VRF is a virtual routing and forwarding instance that isolates the management traffic from other traffic on the switch. By creating a dedicated management VRF and assigning the management port to it, the administrator can enhance the security and performance of the management access to the switch. The other options are incorrect because they either do not apply to switches with dedicated management ports or do not follow Aruba-recommended best practices.

NEW QUESTION # 53
The administrator notices that wired guest users that have exceeded their bandwidth limit are not being disconnected Access Tracker in ClearPass indicates a disconnect CoA message is being sent to the AOS-CX switch.
An administrator has performed the following configuration

What is the most likely cause of this issue?

• A. The SSL certificate for CPPM has not been added as a trust point on the switch
• B. There is a time difference between the switch and the ClearPass Policy Manager
• C. Change of Authorization has not been globally enabled on the switch
• D. There is a mismatch between the RADIUS secret on the switch and CPPM.

Answer: C

Explanation:
Explanation
Change of Authorization (CoA) is a feature that allows ClearPass Policy Manager (CPPM) to send messages to network devices such as switches to change the authorization state of a user session. CoA requires that both CPPM and the network device support this feature and have it enabled. For AOS-CX switches, CoA must be globally enabled using the command radius-server coa enable. If CoA is not enabled on the switch, the disconnect CoA message from CPPM will be ignored and the user session will not be terminated. References:

NEW QUESTION # 54
You are deploying Aruba CX 6300's with the customers requirement to only allow one (1) VoIP phone and one (1) device.
The following local role gets assigned to the phone
port-access rote VoIP device-traffic-class voice
What set of commands best fits this requirement?

• A. interface 1/1/1
  aaa authentication port-access client-limit 1
  aaa authentication port-access auth-mode device-mode
• B. interface 1/1/1
  aaa authentication port-access auth-mode multi-domain
• C. interface 1/1/1
  aaa authentication port-access client-limit 2
  aaa authentication port-access auth-mode client-mode
• D. interface 1/1/1
  aaa authentication port-access client-limit multi-domain 2 aaa authentication port-access auth-mode multi-domain

Answer: D

Explanation:
Aruba CX 6300 switches support various features to control the port access for different types of devices, such as client mode, device mode, and multidomain mode. These features can help limit the number of clients that can connect to a port and prevent unauthorized devices from accessing the network.
This is because option C shows how to configure the client limit and the auth-mode for a specific port using the interface command and the aaa authentication port-access command. The client limit specifies the maximum number of clients that can connect to a port. The auth-mode specifies the authentication mode for the port. In this case, option C sets both parameters to multi-domain mode, which allows only one voice device and one data device to be authenticated on a port

What is a primary benefit of BSS coloring?

• A. BSS color tags improve security by identifying rogue APS and tagging them as threats.
• B. BSS color tags are applied to WI-Fi channels and can reduce the threshold tor interference
• C. BSS color tags improve performance by allowing APS on the same channel to be farther apart
• D. BSS color tags are applied on the wireless controllers and can reduce the threshold for interference_

Answer: B

Explanation:
Explanation
The primary benefit of BSS coloring is D. BSS color tags are applied to Wi-Fi channels and can reduce the threshold for interference.
BSS coloring is a mechanism that allows Wi-Fi 6 devices to mark each frame with a color code that identifies the BSS (Basic Service Set) it belongs to. This helps differentiate between frames from different BSSs that share the same channel and avoid unnecessary collisions and backoffs. BSS coloring also introduces an adaptive threshold for interference, which means that Wi-Fi 6 devices can adjust the signal strength value that determines whether a channel is busy or not based on the current network environment. This allows for more efficient use of spectrum and higher throughput in dense scenarios12.

NEW QUESTION # 58
Two AOS-CX switches are configured with VSX at the the Access-Aggregation layer where servers attach to them An SVI interface is configured for VLAN 10 and serves as the default gateway for VLAN 10. The ISL link between the switches fails, but the keepalive interface functions. Active gateway has been configured on the VSX switches.

What is correct about access from the servers to the Core? (Select two.)

• A. Server 2 cannot access the core layer.
• B. Server 1 can access the core layer via the keepalrve link
• C. Server 1 can access the core layer via both uplinks
• D. Server 1 and Server 2 can communicate with each other via the core layer
• E. Server 1 can access the core layer on only one uplink
• F. Server 2 can access the core layer via the keepalive link

Answer: C,D

Explanation:
Explanation
These are the correct statements about access from the servers to the Core when the ISL link between the switches fails, but the keepalive interface functions. Server 1 can access the core layer via both uplinks because it is connected to VSX-A, which is still active for VLAN 10. Server 2 can also access the core layer via its uplink to VSX-B, which is still active for VLAN 10 because of Active Gateway feature. Server 1 and Server 2 can communicate with each other via the core layer because they are in the same VLAN and subnet, and their traffic can be routed through the core switches. The other statements are incorrect because they either describe scenarios that are not possible or not relevant to the question. References:

NEW QUESTION # 59
How is Dynamic Multicast Optimization (DMO) implemented in an HPE Aruba wireless network?

• A. The AP uses OOS to provide equal air time for multicast traffic,
• B. The controller converts multicast streams into unicast streams.
• C. DMO is configured individually tor each SSID in use in the network.
• D. DMO is configured globally for each SSID in use in the network.

Answer: C

Explanation:
Explanation
The correct answer is A. DMO is configured individually for each SSID in use in the network.
DMO is a feature that allows the AP to convert multicast streams into unicast streams over the wireless link.
This enhances the quality and reliability of streaming video, while preserving the bandwidth available to the non-video clients. DMO is configured individually for each SSID in use in the network, as different SSIDs may have different multicast requirements.
According to the Aruba document Configuring WLAN Settings for an SSID Profile, one of the steps to configure DMO is:
Dynamic multicast optimization: Select Enabled to allow IAP to convert multicast streams into unicast streams over the wireless link. Enabling Dynamic Multicast Optimization (DMO) enhances the quality and reliability of streaming video, while preserving the bandwidth available to the non-video clients.
The other options are incorrect because:
B: The AP does not use QoS to provide equal air time for multicast traffic. QoS is a feature that prioritizes different types of traffic based on their importance and latency sensitivity. QoS does not affect how multicast streams are transmitted over the wireless link.
C; DMO is not configured globally for each SSID in use in the network. DMO is configured individually for each SSID, as different SSIDs may have different multicast requirements.
D: The controller does not convert multicast streams into unicast streams. The AP does the conversion, as it is closer to the wireless clients and can optimize the transmission based on the client capabilities and channel conditions.

With Core-1. what is the default value for config-revision?

• A. 1-0
• B. 0. 0
• C. 0
• D. 1

Answer: C

Explanation:
The default value for config-revision on Core-1 is 0. Config-revision is a parameter that indicates the configuration version of a VSX pair. It is used to synchronize the configuration between the VSX peers and to detect any configuration mismatch. The config-revision value is set to 0 by default on both VSX peers and is incremented by 1 every time a configuration change is made on either peer. The other options are incorrect because they do not reflect the default value of config-revision.

NEW QUESTION # 62
What is the best practice for handling voice traffic with dynamic segmentation on AOS-CX switches?

• A. Switch authentication and user-based tunneling of the voice traffic.
• B. Switch authentication and local forwarding of the voice traffic
• C. Controller authentication and port-based tunneling of all traffic
• D. Central authentication and port-based tunneling of the voice traffic.

Answer: B

Explanation:
Explanation
This is the best practice for handling voice traffic with dynamic segmentation on AOS-CX switches. Dynamic segmentation is a feature that allows AOS-CX switches to tunnel user traffic to a controller or another switch based on user roles and policies. For voice traffic, it is recommended to use switch authentication and local forwarding, which means the voice devices are authenticated by the switch and their traffic is forwarded locally without tunneling. This reduces latency and jitter for voice traffic and improves voice quality. The other options are incorrect because they either use central authentication or tunneling, which are not optimal for voice traffic. References:

NEW QUESTION # 63
A customer wants to enable wired authentication across all their CX switches One of the requirements is that the switch must be able to authenticate a single computer connected through a VoIP phone.
Which feature should be enabled to support this requirement?

• A. Multi-Domain Authentication
• B. MAC Authentication
• C. Multi-Auth Mode
• D. Device-Based Mode

Answer: A

Explanation:
Explanation
Multi-Domain Authentication is the feature that should be enabled to support the requirement that the switch must be able to authenticate a single computer connected through a VoIP phone. Multi-Domain Authentication is a feature that allows an Aruba CX switch to apply different authentication methods and policies to different devices connected to the same port. For example, a VoIP phone and a computer can be connected to the same port using a single cable, but they can be authenticated separately using different credentials and assigned to different VLANs. The other options are incorrect because they either do not support multiple devices on the same port or do not provide authentication. References:

NEW QUESTION # 64
What is an OSPF transit network?

• A. a network on which a router discovers at least one neighbor
• B. a network that connects to a different routing protocol
• C. a network that uses tunnels to connect two areas
• D. a special network that connects two different areas

Answer: C

Explanation:
An OSPF transit network is a network that has at least two routers that are connected by a multi-access link and can forward traffic for other networks1. A transit network is different from a stub network, which has only one router connected to it and does not forward traffic for other networks2. A transit network is also different from a virtual link, which is a logical connection between two areas that are not physically adjacent2. A transit network is not necessarily connected to a different routing protocol, although it can be if the router performs redistribution2. Therefore, the correct answer is C. A network on which a router discovers at least one neighbor.

NEW QUESTION # 65
Describe the difference between Class of Service (CoS) and Differentiated Services Code Point (DSCP).

• A. CoS is only used to determine CLASS of traffic DSCP is only used to differentiate between different Classes.
• B. CoS is only contained in VLAN Tag fields DSCP is in the IP Header and preserved throughout the IP packet flow
• C. They are similar and can be used interchangeably.
• D. CoS has much finer granularity than DSCP

Answer: B

Explanation:
Explanation
CoS and DSCP are both methods of marking packets for quality of service (QoS) purposes. QoS is a mechanism that allows network devices to prioritize and differentiate traffic based on certain criteria, such as application type, source, destination, etc. CoS stands for Class of Service and is a 3-bit field in the 802.1Q VLAN tag header. CoS can only be used on Ethernet frames that have a VLAN tag, and it can only be preserved within a single VLAN domain. DSCP stands for Differentiated Services Code Point and is a 6-bit field in the IP header. DSCP can be used on any IP packet, regardless of the underlying layer 2 technology, and it can be preserved throughout the IP packet flow, unless it is modified by intermediate devices.
