NO.47 With the configuration oftwo CX 8325 switches in the VSX cluster, how would you prepare a link- aggregation for a 7000 gateway for a zero-touch provision to support protocol-based port redundancy?

The goal is to configure a Link Aggregation Group (LAG) on a VSX cluster (pair of CX 8325 switches) that connects to an Aruba 7000 series gateway undergoing Zero Touch Provisioning (ZTP). The LAG needs to support “protocol-based port redundancy” (LACP) and allow connectivity during ZTP.
* VSX Requirement:Since the LAG connects to two separate physical switches operating as a VSX pair, the LAG must be configured as a Multi-Chassis LAG (MC-LAG) on the switches. This allows the gateway to form a single LAG across both upstream devices. The command multi-chassis under the interface lag <id> context enables this.
* Protocol Redundancy Requirement:”Protocol-based port redundancy” indicates that Link Aggregation Control Protocol (LACP) should be used to dynamically negotiate and manage the LAG bundle between the switches and the gateway. The command lacp mode active enables LACP in active negotiation mode.
* ZTP Requirement:During ZTP, the gateway might not have its full configuration, including LACP settings, enabled immediately. To ensure the gateway can establish basic IP connectivity for ZTP (e.g., reach Activate/Central via DHCP/DNS), the switch ports should allow traffic even if LACP negotiation hasn’t completed. The lacp fallback feature enables this, allowing individual LAG member ports to become active if LACP PDUs are not received from the peer.
* Analyzing the Options:
* A)Configures lacp mode active and lacp fallback butlacksthe multi-chassis command required for VSX.
* B)Correctly configures the LAG as multi-chassis, enables lacp mode active, and enables lacp fallback. This meets all requirements.
* C)Configures multi-chassis but uses potentially older or less standard syntax lacp enable and lacp fail-over instead of lacp mode active and lacp fallback.
* D)Lacks the multi-chassis command and uses potentially older/less standard syntax.
* Conclusion:Option B provides the complete and correct configuration using standard AOS-CX syntax to create an MC-LAG on the VSX pair with LACP enabled for redundancy and LACP fallback enabled to support gateway connectivity during ZTP.

NO.48 Match each BGP element to its description.

NO.49 Which set of commands will apply the device profile ‘AP’ to the device shown in the LLDP neighbor output below?

NO.50 Match the BGP connection slates to the conditions thatcould have caused that state.

Explanation:
The router is able to process update messages. –>established
The router is waiting for the neighbor’s open message. –>open sent
Routers have agreed on matching feature sets. –>open confirm
The session establishment has timed out. –>idle
This question requires matching BGP connection states from the BGP Finite State Machine (FSM) to descriptions of conditions that occur within or lead to those states.
* Idle:This is the initial state where BGP awaits a start event or retries after a failure. It’s also the state entered upon error detection or session closure, including timeouts during connection attempts.
* Matches:”The session establishment has timed out.” – A timeout during the connection process forces the BGP process back to the Idle state to potentially retry later.
* OpenSent:After a TCP connection is established, the local router sends a BGP OPEN message with its parameters (AS number, capabilities, etc.) and transitions to the OpenSent state while waiting to receive an OPEN message from its BGP neighbor.
* Matches:”The router is waiting for the neighbor’s open message.”
* OpenConfirm:Once the router receives an OPEN message from its neighbor and validates the parameters (e.g., matching AS, compatible capabilities), it sends a KEEPALIVE message and moves to the OpenConfirm state. It waits for a KEEPALIVE from the neighbor to confirm the session. Basic parameter checks and capability negotiations are successfully completed in this phase.
* Matches:”Routers have agreed on matching feature sets.” – This agreement happens upon successful validation of the OPEN messages exchanged.
* Established:This is the final, stable state where BGP peering is successful. Both routers have accepted each other’s parameters via the OPEN messages and confirmed the session with KEEPALIVEs. In this state, the routers can exchange UPDATE messages containing routing information.
* Matches:”The router is able to process update messages.”

NO.65 A customer is trialing the below colorless port configuration on a single switch and has noticed that users roaming to access points connected to the test switch are unable to receive an IP address on the corporate Wi- R network, which is operating in bridged mode All other SSIDs are working as expected and the AP is Online in HPE Aruba Networking Central.
The security team reports that there have been no failed authentications m HPE Aruba Networking ClearPass Access Tracker and that the last entry for the wiredport is returning the KADIUS Aruba-User-Hold attribute
‘Access_Point.
Which configuration change is required to resolve the issue?

port-access client-move enable

interface 1/1/1-1/1/48
aaa authentication port-access client-limited 0

interface 1/1/1/1-1/48
port-access onboarding-method concurrent enable

port access role Access_point auth-mode device-mode

The issue involves users roaming to APs connected to a test switch failing to receive an IP address on the corporate Wi-Fi network (bridged mode), with ClearPass reporting a RADIUS Aruba-User-Role attribute of Access_Point. The goal is to identify the configuration change needed to resolve this issue.
* Analysis of Options:
* Option A (port-access client-move enable):Enables client movement between ports but does not address the AP authentication issue.
* Option B (aaa authentication port-access client-limit 0):Correct. Setting the client limit to 0 on the switch ports (1/1/1-1/1/48) disables MAC authentication for APs, allowing them to be treated as trusted devices and preventing the application of an incorrect role.
* Option C (port-access onboarding-method concurrent enable):Enables concurrent onboarding but is unrelated to the AP role issue.
* Option D (port-access role Access_point auth-mode device-mode):Configures a device mode role but does not resolve the IP assignment issue caused by incorrect authentication.
* Why Option B is Correct:The issue arises because the switch is applying 802.1X or MAC authentication to the AP ports, resulting in ClearPass assigning the Access_Point role, which restricts client connectivity. By setting aaa authentication port-access client-limit 0 on the AP-connected ports (1
/1/1-1/1/48), the switch disables port-access authentication for these ports, treating the APs as trusted devices. This allows clients to authenticate properly via the AP and receive IP addresses in bridged mode, resolving the issue.
* Relevance to Certification Objectives:
* WLAN (9%):Involves troubleshooting wireless functions and Layer 2 issues related to AP connectivity.
* Authentication/Authorization (9%):Includes troubleshooting ClearPass integration and 802.1X configurations.
* Security (10%):Covers troubleshooting wired 802.1X implementations.

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.

“Network Resiliency and virtualization” (8%) and “Routing” (16%) objectives.

NO.67 You want to use OSPF to advertise a only /16 summary route for the SVIs below to a neighbor in the same area (area 0).

NO.68 Refer to the exhibit.

Acme Corp has VM workload running downstream of ToR-1 and has noticed performance degradation. They suspect ToR-1 uplinks are periodically over utilized. A partner has suggested you migrate your legacy 1U Coie-1 and Cote-2 to the CX 6400 series.
Which aspects of this platform would solve the customer’s problem, while focusing on implementing HPE Aruba Networking best practices? (Select two.)

The CX 6400 series supports multiple active forwardingpathways from ToR-1 based on multi-region design.

The proposed new core’s VSF capabilityallows multiple active forwarding pathways from ToR-1 based while eliminating the need for STP.

The proposed solutions backplane stacking permits the directly connected ESXI hosts to load balance using active LACP.

MC-LAG permits Core-1 and Core-2 to present the edge 602.3ad device as a common system ID”

The question involves a customer experiencing performance degradation due to periodic overutilization of ToR-1 uplinks to legacy Core-1 and Core-2 switches. The proposed solution is to migrate to CX 6400 series switches, and the task is to identify which aspects of the CX 6400 platform address the issue while adhering to HPE Aruba Networking best practices.
* Analysis of Options:
* Option A:Incorrect. The CX 6400 does not support “multi-region design” as a feature for active forwarding pathways.
* Option B:Correct. Virtual Switching Framework (VSF) on the CX 6400 allows multiple active forwarding pathways by creating a single logical switch from multiple physical switches, eliminating the need for STP in the core and reducing uplink congestion.
* Option C:Incorrect. Backplane stacking does not directly enable ESXi hosts to load balance using active LACP; this is unrelated to uplink utilization.
* Option D:Correct. Multi-Chassis Link Aggregation (MC-LAG) allows Core-1 and Core-2 to form a single logical 802.3ad (LACP) device, enabling active-active uplinks from ToR-1 and load balancing traffic to prevent overutilization.
* Why B and D are Correct:The performance degradation is caused by uplink overutilization, likely due to STP blocking redundant paths or inefficient load balancing. The CX 6400’s VSF capability combines multiple switches into a single logical device, allowing all uplinks from ToR-1 to be active without relying on STP, which often blocks redundant paths. MC-LAG further enhances this by presenting Core-1 and Core-2 as a single LACP system, enabling ToR-1 to use all uplinks actively via LACP load balancing. These features align with HPE Aruba Networking best practices for high-availability and performance in campus core deployments.
* Relevance to Certification Objectives:
* Network Resiliency and Virtualization (8%):Designing and troubleshooting VSF and MC- LAG for resiliency and redundancy.
* Performance Optimization (6%):Analyzing and remediating uplink utilization issues.
* Connectivity (9%):Applying advanced networking architectures like VSF and MC-LAG.
