NEW QUESTION # 57
A system engineer needs to preconfigure several Aruba CX 6300 switches that will be sent to a remote office An untrained local field technician will do the rollout of the switches and the mounting of several AP-515s and AP-575S. Cables running to theAPs are not labeled.
The VLANs are already preconfigured to VLAN 100 (mgmt), VLAN 200 (clients), and VLAN 300 (guests) What is the correct configuration to ensure that APs will work properly?

Answer: B

Explanation:
Explanation
Option C is the correct configuration to ensure that APs will work properly. It uses the ap command to configure a port profile for APs with VLAN 100 as the native VLAN and VLAN 200 and 300 as tagged VLANs. It also enables LLDP on the ports to discover the APs and assign them to the port profile automatically. The other options are incorrect because they either do not use the ap command, do not enable LLDP, or do not configure the VLANs correctly. References:

NEW QUESTION # 58
A customer is looking Tor a wireless authentication solution for all of their loT devices that meet the following requirements
- The wireless traffic between the IoT devices and the Access Points must be encrypted
- Unique passphrase per device
- Use fingerprint information to perform role-based access
Which solutions will address the customer's requirements? (Select two.)

A. MPSK Local with EAP-TLS
B. MPSK and an internal RADIUS server
C. Local User Derivation Rules
D. ClearPass Policy Manager
E. MPSK Local with MAC Authentication

Answer: B,D

Explanation:
Explanation
MPSK is a feature that allows device-specific or group-specific passphrases for WPA2 PSK-based deployments. The passphrases are generated by a RADIUS server such as ClearPass Policy Manager and sent to the APs. The wireless traffic between the IoT devices and the APs is encrypted using the passphrases. The passphrases can also be used to perform role-based access by mapping them to different VLANs and user roles
12. ClearPass Policy Manager is a network access control solution that can provide device fingerprinting and profiling for IoT devices based on various attributes such as MAC address, DHCP options, HTTP user agents, etc3. ClearPass Policy Manager can also integrate with other IoT platforms and services to enhance the visibility and security of IoT devices. References: 1

NEW QUESTION # 60
A customer just upgraded aggregation layer switches and noticed traffic dropping for 120 seconds after the aggregation layer came online again. What is the best way to avoid having this traffic dropped given the topology below?

A. Configure the linkup delay timer to exclude LAGS 101 and 102, which will allow time for routing adjacencies to form and to learn upstream routes
B. Configure the linkup delay timer to include LAGs 101 and 102, which will allow time for routing adjacencies lo form and to learn upstream routes
C. Configure the linkup delay timer to 120 seconds, which will allow the right amount of time for the initial phase to sync
D. Configure the linkup delay timer to 240 seconds to double the amount of lime for the initial phase to sync

Answer: B

Explanation:
The reason is that the linkup delay timer is a feature that delays bringing downstream VSX links up, following a VSX device reboot or an ISL flap. The linkup delay timer has two phases: initial synchronization phase and link-up delay phase.
The initial synchronization phase is the download phase where the rebooted node learns all the LACP+MAC+ARP+STP database entries from its VSX peer through ISLP. The initial synchronization timer, which is not configurable, is the required time to download the database information from the peer.
The link-up delay phase is the duration for installing the downloaded entries to the ASIC, establishing router adjacencies with core nodes and learning upstream routes. The link-up delay timer default value is 180 seconds. Depending on the network size, ARP/routing tables size, you might be required to set the timer to a higher value (maximum 600 seconds).
When both VSX devices reboot, the link-up delay timer is not used.
Therefore, by configuring the linkup delay timer to include LAGs 101 and 102, which are part of the same VSX device as LAG 201, you can ensure that both devices have enough time to synchronize their databases and form routing adjacencies before bringing down their downstream links.

NEW QUESTION # 61
Your customer currently has Iwo (2) 5406 modular switches with MSTP configured as their core switches. You are proposing a new solution. What would you explain regarding the Aruba CX VSX switch pair when the Primary VSX node is replaced and the system MAC is replaced?

A. Configure vMAC on the Primary VSX node under VSX to retain MAC after hardware replacement.
B. During the initial VSX configuration, the system-mac is assigned with a fixed MAC based on VSX ID.
C. VSX will select the MAC address from a node that is a higher ID.
D. VSX will select the MAC address from a node that is the lower ID.

Answer: B

Explanation:
The system-mac command is used to configure a fixed MAC address for the VSX system. This MAC address is used as the source MAC address for all routed traffic from the VSX node. The system-mac command is highly recommended for preventing traffic disruptions when the primary VSX switch restores after the secondary VSX switch, such as during a primary switch hardware replacement or a power outage2. During the initial VSX configuration, the system-mac is assigned with a fixed MAC based on VSX ID. The system-mac command can be used to change this default MAC address if needed2. Therefore, answer D is correct.

NEW QUESTION # 62
A network engineer recently identified that a wired device connected to a CX Switch is misbehaving on the network To address this issue, a new ClearPass policy has been put in place to prevent this device from connecting to the network again.
Which steps need to be implemented to allow ClearPass to perform a CoA and change the access for this wired device? (Select two.)

A. Use Dynamic Segmentation.
B. Configure dynamic authorization on the switchport
C. Configure dynamic authorization on the switch.
D. Bounce the switchport
E. Confirm that NTP is configured on the switch and ClearPass

Answer: C,D

Explanation:
Explanation
CoA (Change of Authorization) is a feature that allows ClearPass to dynamically change the authorization and access privileges of a device after it has been authenticated1. CoA uses RADIUS messages to communicate with the network device and instruct it to perform an action, such as reauthenticating the device, applying a new VLAN or user role, or disconnecting the device2.
To enable CoA on a CX switch, the network engineer needs to configure dynamic authorization on the switch, which is a global command that allows the switch to accept RADIUS messages from ClearPass and execute the requested actions3. The network engineer also needs to specify the IP address and shared secret of ClearPass as a dynamic authorization client on the switch3.
To trigger CoA for a specific wired device, the network engineer needs to bounce the switchport, which is an action that temporarily disables and re-enables the port where the device is connected. This forces the device to reauthenticate and receive the new policy from ClearPass. Bouncing the switchport can be done manually by using the interface shutdown and no shutdown commands, or automatically by using ClearPass as a CoA server and sending a RADIUS message with the Port-Bounce-Host AVP (Attribute-Value Pair).

NEW QUESTION # 63
Using Aruba best practices what should be enabled for visitor networks where encryption is needed but authentication is not required?

A. Open Network Access
B. Opportunistic Wireless Encryption
C. Wi-Fi Protected Access 3 Enterprise
D. Wired Equivalent Privacy

Answer: B

Explanation:
Opportunistic Wireless Encryption (OWE) is a feature that provides encryption for open wireless networks without requiring authentication. OWE uses an enhanced version of the 4-way handshake to establish a pairwise key between the client and the AP, which is then used to encrypt the wireless traffic using WPA2 or WPA3 protocols. OWE can be used for visitor networks where encryption is needed but authentication is not required. Reference: https://www.arubanetworks.com/assets/tg/TG_OWE.pdf

NEW QUESTION # 64
The customer needs a network hardware refresh to replace an aging Aruba 5406R core switch pair using spanning tree configuration with Aruba CX 8360-32YC switches What is the benefit of VSX clustering with the new solution?

A. faster MSTP converge processing
B. dual Aruba AP LAN port connectivity for PoE redundancy
C. dual control plane provides better resiliency
D. stacked data-plane

Answer: C

Explanation:
VSX clustering is a feature that allows two Aruba CX switches to operate as a single logical device, providing high availability, scalability, and simplified management. VSX clustering has several benefits over spanning tree configuration, such as:
Dual control plane provides better resiliency. Unlike stacking, where switches share a single control plane, VSX switches have independent control planes that synchronize their states over an inter-switch link (ISL). This means that if one switch fails or reboots, the other switch can continue to operate without affecting traffic flows or network services.
Active-active forwarding provides better performance. Unlike spanning tree, where some links are blocked to prevent loops, VSX switches use all available links for forwarding traffic, providing load balancing and increased bandwidth utilization.
Multichassis LAG provides better redundancy. Unlike single-chassis LAG, where all member ports belong to one switch, VSX switches can form multichassis LAGs with downstream or upstream devices, where member ports are distributed across both switches. This provides link redundancy and seamless failover in case of switch or port failure.

NEW QUESTION # 65
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. Authentication survivability
B. MAC caching
C. Opportunistic key caching
D. MAC Authentication

Answer: A

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.

NEW QUESTION # 67
Which Aruba AP mode is sending captured RF data to Aruba Central for waterfall plot?

A. Hybrid Mode
B. Dual Mode
C. Spectrum Monitor
D. Air Monitor

Answer: C

Explanation:
Spectrum Monitor is an Aruba AP mode that is sending captured RF data to Aruba Central for waterfall plot. Spectrum Monitor is a mode that allows an AP to scan all channels in both 2.4 GHz and 5 GHz bands and collect information about the RF environment, such as interference sources, noise floor, channel utilization, etc. The AP then sends this data to Aruba Central, which is a cloud-based network management platform that can display the data in various formats, including waterfall plot. Waterfall plot is a graphical representation of the RF spectrum over time, showing the frequency, amplitude, and duration of RF signals. The other options are incorrect because they are either not AP modes or not sending RF data to Aruba Central.

NEW QUESTION # 68
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-Personal
B. Change the SSID to WPA3-Enterprise (CCM).
C. Change the SSID to WPA3-Enterpnse (CNSA).
D. Change the SSID to WPA3-Enhanced Open

Answer: C

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 # 69
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 a remote access point.
B. The AP is using a directional antenna.
C. The AP is an outdoor access point.
D. The AP is configured in Mesh mode

Answer: B

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 # 71
What steps are part of the Key Management workflow when a wireless device is roaming from AP1 to AP2?
(Select two.)

A. The Key Management service then generates R1 keys for AP2's neighbors.
B. AP1 will cache the client's information and send it to the Key Management service
C. A client associates and authenticates with the AP2 after roaming from AP1
D. The Key Management service receives a list of all AP1 s neighbors from AirMatch.
E. The Key Management service receives from AirMatch a list of all AP2's neighbors

Answer: A,B

Explanation:
Explanation
The correct steps that are part of the Key Management workflow when a wireless device is roaming from AP1 to AP2 are A and D.
A: AP1 will cache the client's information and send it to the Key Management service. This is true because when a client associates and authenticates with AP1, AP1 will generate a pairwise master key (PMK) for the client and store it in its cache. AP1 will also send the PMK and other client information, such as MAC address, VLAN, and SSID, to the Key Management service, which is a centralized service that runs on Aruba Mobility Controllers (MCs) or Mobility Master (MM) devices1. The Key Management service will use this information to facilitate fast roaming for the client.
D: The Key Management service then generates R1 keys for AP2's neighbors. This is true because when the Key Management service receives the client information from AP1, it will use the PMK to derive R0 and R1 keys for the client. R0 keys are used to generate R1 keys, which are used to generate pairwise transient keys (PTKs) for encryption. The Key Management service will distribute the R1 keys to AP2 and its neighboring APs, which are determined by AirMatch based on RF proximity2. This way, when the client roams to AP2 or any of its neighbors, it can skip the 802.1X authentication and use the R1 key to quickly generate a PTK with the new AP3.
B: The Key Management service receives from AirMatch a list of all AP2's neighbors. This is false because the Key Management service does not receive this information from AirMatch directly. AirMatch is a feature that runs on MCs or MM devices and optimizes the RF performance of Aruba devices by using machine learning algorithms. AirMatch periodically sends neighbor reports to all APs, which contain information about their nearby APs based on signal strength and interference. The APs then send these reports to the Key Management service, which uses them to determine which APs should receive R1 keys for a given client2.
C: The Key Management service receives a list of all AP1 s neighbors from AirMatch. This is false for the same reason as B. The Key Management service does not receive this information from AirMatch directly, but from the APs that send their neighbor reports.
E: A client associates and authenticates with the AP2 after roaming from AP1. This is false because a client does not need to authenticate with AP2 after roaming from AP1 if it has already authenticated with AP1 and received R1 keys from the Key Management service. The client only needs to associate with AP2 and perform a four-way handshake using the R1 key to generate a PTK for encryption3. This is called fast roaming or
802.11r roaming, and it reduces the latency and disruption caused by full authentication.
