The correct answer is B. Spanning-tree instance VLAN mapping. To load-balance VLANs with MSTP, you need to configure the same VLAN-to-instance mapping on all switches in the same MST region. This means that you need to assign different VLANs to different MST instances, and then adjust the spanning tree parameters (such as priority, cost, or port role) for each instance to achieve the desired load balancing. For example, you can make one switch the root for instance 1 and another switch the root for instance 2, and then map half of the VLANs to instance 1 and the other half to instance 2.
According to the Cisco document Understand the Multiple Spanning Tree Protocol (802.1s), one of the steps to configure MST is: Split your set of VLANs into more instances and configure different MST settings for each of these instances. In order to easily achieve this, elect Bridge D1 to be the root for VLANs 501 through 1000, and Bridge D2 to be the root for VLANs 1 through 500. These statements are true for this configuration: Switch D1(config)#spanning-tree mst configuration Switch D1(config-mst)#instance 1 vlan 501-1000
Switch D1(config-mst)#exit
Switch D1(config)#spanning-tree mst 1 priority 0

Switch D2(config)#spanning-tree mst configuration Switch D2(config-mst)#instance 2 vlan 1-500
Switch D2(config-mst)#exit
Switch D2(config)#spanning-tree mst 2 priority 0 The above commands create two MST instances, 1 and 2, and map VLANs 501-1000 to instance 1 and VLANs 1-500 to instance 2. Then, they make switch D1 the root for instance 1 and switch D2 the root for instance 2.
The other options are incorrect because:
A. Spanning-tree bpdu-guard setting is a security feature that disables a port if it receives a BPDU from an
unauthorized device. It does not affect load balancing with MSTP.
C. Spanning-tree CIST mapping is not a valid command. CIST stands for Common and Internal Spanning
Tree, which is the spanning tree instance that runs within an MST region and interacts with other regions or non-MST switches. D. Spanning-tree root-guard setting is another security feature that prevents a port from becoming a root port if it receives superior BPDUs from another switch. It does not affect load balancing with MSTP.

Wi-Fi calling is a feature that allows you to make or receive voice calls over Wi-Fi instead of cellular network. Wi-Fi calling can provide better voice quality and reliability in areas with poor or no cellular coverage.

The auditors role is the default AOS-CX user role that meets the requirements of having Web UI access to the System > Log page and having access to the GET method for REST API for the /logs/event resource.
The auditors role has a level of 1 and allows read-only access to most commands except those related to security or passwords. It also allows access to the Web UI and REST API with limited permissions. The other options are incorrect because they either have higher levels of access or do not allow access to the
Web UI or REST API.

The active gateway feature is used to provide active-active layer 3 default gateway for hosts on the same subnet. It allows the switch to convert multicast streams into unicast streams over the wireless link, which improves the quality and reliability of streaming video, while preserving the bandwidth available to the non-video clients. The active gateway feature is unique to VSX configuration because it eliminates the need for VRRP and avoids traffic being pushed over the ISL link, which can cause latency in the network 12.
The correct answer to the question is C. Sixteen different VMACs are supported for each IPv4 and IPv6 stack simultaneously. This means that you can have a maximum of eight VMACs for IPv4, and a maximum of eight VMACs for IPv6, on a VSX pair. Only 15 VMACs are supported on 6400 switch series 2.
The other options are incorrect because:
A. Sixteen different VMACs are not supported total as shared. They are supported for each IPv4 and IPv6
stack separately.
B. Active gateway can be used without MSTP instances. MSTP is a protocol that allows multiple spanning
tree instances to coexist on the same switch, but it does not affect how active gateway works.
D. Active gateway does not copy traffic over the ISL link for an optimized path. It avoids using the ISL link
for routed traffic and uses the local switch interface MAC instead of the virtual MAC address (VMAC) for source address 1.

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 outage 2. 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 needed 2. Therefore, answer D is correct.

802.11k is the correct answer because it defines radio resource measurement mechanisms that help clients learn more about the surrounding RF environment, including neighbor-related information. This can improve roaming efficiency by giving the client more useful data when selecting a candidate AP. 802.11r is focused on fast transition keying and reduced reauthentication delay. 802.11w protects management frames, and 802.3at is a PoE standard unrelated to WLAN roaming intelligence.

RadSec is the right answer because it protects RADIUS traffic by carrying it over TLS, providing confidentiality and server authentication for the AAA exchange path. This addresses the stated concern about exposure between the AP and the cloud-based RADIUS service. EAP-TLS strengthens client authentication but does not itself secure the RADIUS transport hop in the same way. GRE is a tunneling technology unrelated to RADIUS protection, and WPA3-Personal changes the client access method rather than securing the AP-to-RADIUS transport.

According to the Aruba Documentation Portal1, the Aruba CX 6200F VSF stack is a feature that allows you to create a virtual switching framework (VSF) with up to eight members that can be managed as a single logical device. The VSF stack provides benefits such as load balancing, failover, redundancy, and security.
To add a new device to the VSF stack, you need to configure the device with the VSF command vsf member and specify the type, link, and secondary-member information. The type of the new device can be one of the following: JL726A, JL726B, JL726C, or JL726D. The link is the interface that connects the new device to the existing VSF members. The secondary-member is an optional parameter that specifies which member will act as a backup in case of a failure.

According to the Aruba Documentation Portal1, the firewall role derivation flow in the correct order is: Server derived role User derived role Authentication default role Initiation role assigned

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 points 1.
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 points 2.
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 points 3. 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.

This is the correct statement about what happens when a client attempts to join the network and the WLAN is configured with OWE (Opportunistic Wireless Encryption). OWE is a standard that provides encryption for open networks without requiring any authentication or credentials from the client or the network. OWE uses a Diffie-Hellman key exchange mechanism to establish a secure session between the client and the AP without exchanging any authentication information. The other options are incorrect because they either describe scenarios that require authentication or encryption methods that are not used by OWE.

The information that the Inter-Switch Link Protocol configuration uses in the configuration created is B.
MAC tables.
The Inter-Switch Link Protocol (ISL) is a protocol that enables the synchronization of data and state information between two VSX peer switches. The ISL uses a version control mechanism and provides backward compatibility regarding VSX synchronization capabilities. The ISL can span long distances (transceiver dependent) and supports different speeds, such as 10G, 25G, 40G, or 100G1. One of the data components that the ISL synchronizes is the MAC table, which is a database that stores the MAC addresses of the devices connected to the switch and the corresponding ports or VLANs. The ISL ensures that both VSX peers have the same MAC table entries and can forward traffic to the correct destination 2.
The ISL also synchronizes other data components, such as ARP table, LACP states for VSX LAGs, and MSTP states 2.

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.

The correct answers are C and D.
MPSK (Multi Pre-Shared Key) is a feature that allows multiple PSKs to be used on a single SSID, providing device-specific or group-specific passphrases for enhanced security and deployment flexibility for headless
IoT devices 1. MPSK requires MAC authentication against a ClearPass Policy Manager server, which returns the encrypted passphrase for the device in a RADIUS VSA2. ClearPass Policy Manager is a platform that provides role-and device-based network access control for any user across any wired, wireless and VPN infrastructure 3. ClearPass Policy Manager can also use device profiling and posture assessment to assign roles based on device fingerprint information 4. MPSK Local is a variant of MPSK that allows the user to configure up to 24 PSKs per SSID locally on the device, without requiring ClearPass Policy Manager5. MPSK Local can be combined with EAP-TLS (Extensible Authentication Protocol- Transport Layer Security), which is a secure authentication method that uses certificates to encrypt the wireless traffic between the IoT devices and the access points 6. EAP-TLS can also use device certificates to perform role-based access control 6.
Therefore, both ClearPass Policy Manager and MPSK Local with EAP-TLS can meet the customer's requirements for wireless authentication, encryption, unique passphrase, and role-based access for their
IoT devices.
MPSK and an internal RADIUS server is not a valid solution, because MPSK does not support internal RADIUS servers and requires ClearPass Policy Manager789. MPSK Local with MAC Authentication is not a valid solution, because MAC Authentication does not encrypt the wireless traffic or use fingerprint information for role-based access 2. Local User Derivation Rules are not a valid solution, because they do not provide unique passphrase per device or use fingerprint information for role-based access101112.

The correct answer is A. SNMPv3.
SNMPv3 is a protocol that is used to retrieve data stored in a Management Information Base (MIB), which is a database of managed objects in a network. SNMPv3 provides security and access control features that are not available in earlier versions of SNMP. SNMPv3 can also use encryption to protect the data from unauthorized access or modification.
According to the Aruba Certified Professional ?Campus Access document1, one of the skills that this certification validates is: Implement and Analyze the output from common network monitoring tools The document also mentions that the candidate should have a distinguished understanding of different protocols across vendors, which implies that they should be familiar with SNMPv3 and how it can be used to access MIB data.

OWE, also called Enhanced Open in many Aruba workflows, is intended for situations where encryption is required but user authentication is not. It protects traffic on an otherwise open network by establishing encryption without using a shared password or 802.1X. WPA3-Personal requires a passphrase, and WPA3-Enterprise requires 802.1X with a RADIUS-based authentication workflow. A purely open network with captive portal does not provide over-the-air encryption before portal interaction.

Two parts of the solution for these requirements are
Option C and
Option E.
Option C is a part of the solution because it defines a policy-based routing action list named route_test, which specifies the next hop IP address as 10.1.1.253 for the matching traffic. This is the new default route that the user wants to use for the subnet 10.2.250.0/24. The interface null parameter indicates that the traffic will be routed to the next hop without using a specific interface 1.
Option E is a part of the solution because it applies the policy-based routing action list route_test to the VLAN interface 250, which has an IP address of 10.2.250.1/24.
This is the subnet that the user wants to test the new default route for. The apply policy command enables policy-based routing on the interface and associates it with the action list 2.
Option A is not a part of the solution because it defines a policy-based routing action list named route_test, but does not specify the next hop IP address as 10.1.1.253, which is the new default route that the user wants to use. Instead, it specifies a next hop IP address of 10.1.1.254, which is different from the requirement.
Option B is not a part of the solution because it defines a policy-based routing action list named route_test, but does not specify any next hop IP address at all, which is necessary for policy-based routing to work. Instead, it specifies an interface null parameter without any IP address, which is invalid.
Option D is not a part of the solution because it applies the policy-based routing action list route_test to the VLAN interface 200, which has an IP address of 10.2.200.1/24. This is not the subnet that the user wants to test the new default route for, but a different subnet that should not be affected by this change.

MAC caching is the correct feature because it allows returning guest devices to be recognized by their MAC address after the initial successful portal interaction, reducing the need to present the splash page repeatedly. This is a common user-experience improvement for guest access environments where devices often sleep and reconnect. Dynamic authorization is an AAA policy-change mechanism, not a guest portal convenience feature. OSPF graceful restart and port mirroring are unrelated to captive portal behavior.
