QUESTION 40
Exhibit.

In the given example AGG-SW1 and AGG-SW2 use CX 8325 in VSX and Edge-1 withCX 6200F. You want toavcwl sub-optimal path.ng and ISL traffic for the VSX and upstream routers R1 and R2.
What is the HPE Aruba Networkingrecommended solution for me SVIs on the VSX switches connected to R1 and R2?

Configure the VSX SVI using the active-forwarding.

Configure the VSX SVI using the uncast IP.

Configure the VSX SVI using the VRRP virtual-ip.

Configure the VSX SVI using the active-gateway.

The scenario involves a VSX pair (AGG-SW1/SW2) connected upstream to routers R1/R2. The goal is to configure the SVIs on the VSX switches facing these upstream routers optimally to avoid suboptimal L3 paths and unnecessary traffic over the VSX Inter-Switch Link (ISL).
* VSX L3 Interface Options:
* Active Gateway:Primarily designed for downstream SVIs to provide a redundant default gateway to clients/access switches. Not typically used for upstream routed interfaces.
* Active Forwarding:Specifically designed for upstream routed interfaces (physical or SVIs) on a VSX pair. It allows both VSX members to actively route traffic arriving on that interface locally, without needing to forward L3 traffic across the ISL. This ensures optimal routing and utilizes both members effectively.
* Unicast IP (Standard IP):Without specific VSX features, standard routing applies. This could lead to suboptimal paths if, for example, return traffic prefers one VSX switch, but the optimal path requires crossing the ISL.
* VRRP:Can be run between VSX members but adds complexity and is generally superseded by Active Gateway (downstream) or Active Forwarding (upstream) in VSX designs.
* Analysis of Options:
* A. Configure active-forwarding: This enables local L3 forwarding on both VSX members for the upstream SVI, preventing unnecessary ISL traversal for routed traffic. This is the recommended best practice.
* B. Configure unicast IP: Standard configuration, potentially leading to suboptimal paths/ISL usage.
* C. Configure VRRP virtual-ip: Not the recommended approach for upstream links in VSX.
* D. Configure active-gateway: Incorrect, Active Gateway is for downstream SVIs.
* Conclusion:Using active-forwarding on the SVIs facing the upstream routers (R1/R2) is the HPE Aruba Networking recommended solution to ensure optimal routing and minimize L3 traffic across the ISL.

QUESTION 43
Identify the required configuration steps to enable DHCP EndpointProfiling with HPE Aruba Networking ClearPass. (Not all will be used)

Explanation:

To enable DHCP Endpoint Profiling, the switch needs to forward relevant DHCP packets from the client to the ClearPass server. The most common method is configuring the switch to act as a DHCP relay agent for the ClearPass server IP address on the client VLAN’s Switched Virtual Interface (SVI).
In scenarios where port access control (like 802.1X or MAC Auth) is enabled, clients might need to send DHCP requestsbeforethey are fully authenticated. To allow this while maintaining security, a pre- authentication role with limited access (specifically allowing DHCP) can be applied to the port initially.
The logical sequence based on the provided steps, assuming a pre-authentication workflow is intended, is:
* Create the role:Define the pre-authentication role container and associate it with the appropriate initial VLAN if needed.
* Permit DHCP in the role:Apply an Access Control List (ACL) or policy to this role that permits the necessary DHCP traffic (UDP ports 67 and 68). The step provided only mentions UDP 67, which allows the client’s initial Discover/Request packets towards the server/relay. (A complete solution requires allowing return traffic on UDP 68 as well).
* Apply the role:Configure the client-facing physical interface to use this pre-authentication role before the final role is assigned post-authentication.
* Configure DHCP Relay:Configure the ip helper-address <clearpass_ip> command on the client’s VLAN SVI. This instructs the switch to forward the DHCP packets it receives from clients in that VLAN to the ClearPass server (in addition to forwarding them to the actual DHCP server). ClearPass receives these packets and extracts information for profiling.
This sequence ensures that even before full authentication, DHCP is permitted, and the necessary packets are relayed to ClearPass for profiling.

QUESTION 44
Exhibit.

The customer has VSX clusters intwo locations interconnected over an MC-LAG interface.
If active-gateway configuration uses the same virtual IP address and vMAC on each of the VSX nodes, what must you take into consideration0

Transit traffic will Increase over the VSX interconnect MC-LAG.

Each ARP request will result in four responses.

The configuration would end up in an async setup.

Outbound traffic will be load-balancedover all VSX members for each session.

The scenario describes two separate VSX clusters interconnected via MC-LAG, where both clusters are configured to use theexact samevirtual IP address and virtual MAC address for their respective Active Gateway SVIs.
* Active Gateway Scope & Conflict:Active Gateway provides a highly available default gatewaywithina single VSX cluster (L2 domain). The vIP/vMAC combination should be unique within its L2 broadcast domain.
* Interconnecting Clusters with Same vIP/vMAC:When two VSX clusters using the identical Active Gateway vIP/vMAC are interconnected at Layer 2 (even via MC-LAG), this creates a situation where the same active L2 (vMAC) and L3 (vIP) address exists in multiple places within the extended broadcast domain.
* Consequences:This leads to MAC address conflicts and L3 ambiguity. ARP resolution becomes unreliable, potentially causing ARP tables to flap on connected devices. Traffic forwarding becomes unpredictable, as packets destined for the vIP/vMAC might be delivered to the “wrong” cluster. This unstable and unpredictable state is sometimes referred to as an asymmetric or “async” setup.
* Analysis of Options:
* A: ISL traffic might change, but it’s a symptom, not the root problem.
* B: Multiple ARP replies would occur, contributing to the confusion.
* C: The configuration results in an “async setup,” accurately describing the unstable state caused by duplicate active L2/L3 addresses across the interconnected L2 domain.
* D: Load-balancing happens within a cluster; this setup causes conflict, not predictable load balancing across clusters.
* Conclusion:Reusing the same Active Gateway vIP and vMAC across interconnected VSX clusters is not a valid design and leads to an unstable, asymmetric (“async”) environment due to address duplication within the extended L2 domain. Option C best describes this problematic outcome.

QUESTION 49
Youare configuring an HPE Aruba NetworkingGateway Ouster with AOS-10. What is true about 802.1 X functionality incombination with gateways? (Select two.)

Users onL3-oonnoctod gateways need to perform a full authentication after re-association on theAP.

The UDG remains fixed on L2-connected gateways but not on 1.3-connected gateways.

Regardless of using gateways, the CoA message is always sent to the APs.

The gateways areused as a RADIUS proxy, while the AP is theauthenticator.

The gateways actasRADIUS Proxy only in Tunnel and Bridged Mode.

This question asks about 802.1X functionality in an AOS-10 environment involving Gateway Clusters.
* AOS-10 Gateway/802.1X Architecture:
* Authenticator:The Access Point (AP) typically acts as the 802.1X authenticator, handling EAPoL frames with the client.
* RADIUS Proxy:The Gateway Cluster (specifically the cluster leader or UDG anchor) often acts as a RADIUS proxy, forwarding RADIUS messages between the APs and the central RADIUS server (e.g., ClearPass). This simplifies RADIUS configuration as the server only needs to know about the gateway cluster.
* CoA:Change of Authorization messages from the RADIUS server are typically sent to the device acting as the RADIUS client, which is the Gateway Cluster when operating in proxy mode.
* Mobility (L2 vs L3):Roaming behavior and User Designated Gateway (UDG) assignment can differ based on whether clients maintain their IP address (L2 mobility) or potentially require new IP information (L3 mobility). L2-connected gateway deployments generally allow for more seamless UDG persistence compared to L3-connected deployments where the client might roam across subnet boundaries managed by different gateways.
* Re-authentication:Seamless roaming mechanisms aim to minimize full re-authentications during roaming events.
* Analysis of Options:
* A: Full re-authentication after re-association on L3-connected gateways might occur in some scenarios but contradicts the goal of seamless roaming.
* B: States the UDG remains fixed on L2-connected but not on L3-connected gateways. This aligns with the architectural differences in handling mobility across L2 vs L3 boundaries within a cluster.
* C: Incorrect. CoA is generally sent to the RADIUS client/proxy (the Gateway Cluster), not always directly to the APs.
* D: Correct. Gateways commonly act as a RADIUS proxy, while the AP remains the authenticator handling EAPoL with the client.
* E: Incorrect. The RADIUS proxy function is not limited to only Tunnel and Bridged modes.
* Conclusion:Options B and D accurately describe common characteristics of 802.1X operation within an AOS-10 Gateway Cluster architecture.

Restart the routing service so thatBGP auto-discovers its neighbors.

Confirm that appropriate TCP ports are still allowed.

Restart NAT service for the BGP interface.

Confirm that BGP Peer AS has not changed.

QUESTION 52
Exhibit.

After an initial setup of CX 8325 VSX configuration, the active gateway is set up for SVI 10. For testing purposes. SVI 10 on sw-aggi is shut down while traffic from the client connected to Edge-1 is initiated towards the default route.
What is the expected behavior white performing this test?

Traffic is potentially dropped between the client and the destination.

Traffic is forwarded over the ISL without the risk of dropped packets.

Traffic Is unaffected and a 50nsfailover time is expected for agg-sw2 to start traffic forwarding.

Traffic is dropped and vsx-sync will disable SVI10 on agg-sw2 automatically.

QUESTION 53
Exhibit.

VSX cluster is already configured. Your task is to validate a correct configuration for the Edge-1 switch that is connected to a CCTV provider that will install its switching infrastructure. The CCTV switches do not support STP.
What needs to be configured on the Edge-1 switch ports connecting to CCTV-SW1 and CCTV-SW2 to prevent loop problems with the existing setup with automatic recovery features?

configure lag with lacp fallback for CCTV switch ports

configure spanning-tree and TCN-guard timeout for CCTV switch ports

configure spanning-tree with bpdu-guard timeout values for CCTV switch ports

configure spanning-tree with udld for CCTV switch ports

The requirement is to prevent loops on Edge-1 switch ports connected to third-party CCTV switches that do notsupport STP. The solution must also include an automatic recovery feature if a port gets disabled.
* Loop Prevention without STP:When connecting to non-STP devices, standard STP loop prevention (like BPDU Guard) might not work if the connected device doesn’t send BPDUs. AOS-CX offers a feature called loop-protect which sends probes to detect loops in non-STP environments.
* Automatic Recovery:Features that disable ports (like BPDU Guard or Loop Protect) often have a timeout or auto-recovery option (port-disable-timer for Loop Protect) allowing the port to automatically re-enable after a configured period.
* Analysis of Options:
* A: LACP fallback applies to LAGs, not general loop prevention.
* B: TCN-guard is an STP feature, irrelevant here.
* C: Suggests spanning-tree with bpdu-guard timeout. BPDU Guard detects loops by listening for BPDUs, which these CCTV switches don’t send. However, the timeout featuredoesprovide the required automatic recovery mechanism if the portweredisabled by BPDU Guard.
* D: UDLD detects unidirectional links, not typically bridging loops caused by topology.
* Re-evaluation:The ideal AOS-CX feature is loop-protect with port-disable-timer. Since this isn’t explicitly an option, we must evaluate the given choices. Option C is theonlyone that mentions a mechanism (bpdu-guard timeout) providing automatic recovery from a disabled state. While BPDU Guard isn’t the right detection mechanism here, it’s the closest fit regarding the auto- recoveryrequirement. It’s possible the question implicitly assumes some stray BPDUs might trigger it or that it’s the intended “best fit” answer despite the detection mechanism mismatch.
* Conclusion:Given the options, Option C is the most plausible because it includes the timeout feature associated with bpdu-guard, fulfilling the automatic recovery requirement, even though BPDU guard itself is not the ideal detection method for loops involving non-STP devices.
