Answer: C
Explanation
The question involves configuring an OSPF virtual link to extend area 0 across a non-backbone area, based on 
an exhibit (not provided) and four configuration options (A to D). Since the exhibit is unavailable, I will 
assume a typical scenario where a virtual link is needed to connect two area 0 segments through a transit area 
(e.g., area 1).
Analysis of Options (Assumed Context):A virtual link is configured using the area 
virtual-link command in the OSPF process. The correct option likely includes:
Option A:Incorrect syntax or incorrect router ID/area for the virtual link.
Option B:Incorrect configuration, possibly missing the virtual link or using wrong parameters.
Option C:Correct. Likely includes the proper command, e.g., area 1 virtual-link 2.2.2.2, where 
area 1 is the transit area and 2.2.2.2 is the router ID of the remote ABR.
Option D:Incorrect, possibly configuring an unnecessary or incorrect virtual link.
Why Option C is Correct:OSPF requires all areas to connect to the backbone area (area 0). If two area 
0 segments are separated by a non-backbone area (e.g., area 1), a virtual link is configured between the 
Area Border Routers (ABRs) to logically extend area 0 through the transit area. The command area 
 virtual-link is used, specifying the transit area and the router ID of 
the remote ABR. Option C is assumed to provide the correct syntax and parameters based on standard 
OSPF virtual link configurations, ensuring area 0 connectivity and proper route advertisement.
Relevance to Certification Objectives:
Routing (16%):Designing and troubleshooting OSPF topologies, including virtual links.
Troubleshooting (10%):Resolving OSPF area connectivity issues.

Question #:3 - [Network Resiliency and Virtualization]
Exhibit.
After Implementing a distributed overlay with distributed anycast gateways, you noticed that toomany ARP 
packets are being replicated to every access (leaf) switch Which command can you use to optimize the 
network?
vlan 10 arp-suppression vlan 11 arp-suppression
evpn arp-suppression
evpn ip proxy-arp
interface vlan 10 ip proxy-arp interface vlan 11 ip proxy-arp
Answer: B
Explanation
In an EVPN VXLAN distributed overlay network, excessive ARP packet replication (flooding) to all leaf 
switches is observed. We need the command to optimize this.
EVPN ARP Optimization:EVPN uses its control plane (BGP) to distribute MAC and IP address 
reachability information. Leaf switches (VTEPs) learn these mappings. To reduce ARP flooding across 
the VXLAN fabric:

B. 
C. 
D. 
ARP Suppression:VTEPs intercept ARP requests. If the VTEP already knows the MAC address 
for the requested IP (learned via EVPN), it can suppress the ARP request, preventing it from 
being flooded over VXLAN.
Proxy ARP:VTEPs intercept ARP requests. If the VTEP knows the MAC for the requested IP, it 
can generate an ARP reply of the remote host.on behalf
AOS-CX Commands:These features are configured within the EVPN context.
evpn arp-suppression (B): Enables the ARP suppression feature for EVPN.
evpn ip proxy-arp (C): Enables the proxy ARP feature for EVPN.
Options A and D use standard interface/VLAN level arp-suppression or proxy-arp commands, 
which are not specific to optimizing flooding within the EVPN VXLAN fabric itself.
Conclusion:To optimize by reducing the replication/flooding of ARP packets across the EVPN 
VXLAN overlay, enabling evpn arp-suppression (Option B) is the direct command. This leverages the 
EVPN control plane knowledge to stop unnecessary ARP flooding.

"Switching" (19%) and "Routing" (16%) objectives in the context of overlays.
Question #:4 - [WLAN]
Which issue may becausing the new door locks on the APs to notwork?
AT power to the AP is too much.
BT power to the AP is too much.
AF power to the AP is not enough.
AT power to the AP is notenough.
Answer: C
Explanation
New PoE-powered door locks, connected via the PoE passthrough port on Aruba APs, are not working. We 
need to find the likely cause related to PoE power.
PoE Passthrough:An AP feature where the AP, powered by PoE from a switch, provides PoE power 
out to another device connected to one of its Ethernet ports.
Power Budget:The AP must receive enough power from the switch via its PoE input (e.g., 802.3af, 
802.3at, 802.3bt) to power itself meet the power demand of the downstream device (the door lock).and

A. 
B. 
C. 
D. 
PoE Standards Power (Approx. Available to Device):
802.3af (PoE): ~13 Watts
802.3at (PoE+): ~25.5 Watts
802.3bt (PoE++): 51W (Type 3) or 71W (Type 4)
Analysis:Modern APs (especially Wi-Fi 6/6E) can consume significant power themselves (>15W or 
>25W under load). Standard 802.3af PoE (supplying only ~13W) is often insufficient to power both a 
modern AP and a downstream PoE device like a door lock. The AP will power up, but won't enable 
PoE output if its input power budget is insufficient.
Analysis of Options:
A, B: Too much power (AT/BT) isn't the issue; devices only draw what they need.
C: AF power (~13W) received by the AP is very likely to power both the AP and the not enough
door lock.
D: AT power (~25.5W) be insufficient if the combined load of the AP and lock exceeds this, might
but AF being insufficient (C) is a more common limitation.
Conclusion:Insufficient input power to the AP is the most common reason for PoEpassthrough failure. 
802.3af (PoE) power is often inadequate.

primarily focused on automated troubleshooting or visibility.  
C. Automate processes with scripting like Python: AOS-CX supports on-box scripting (NAE) and 
REST APIs, enabling custom automation for monitoring and troubleshooting. While powerful, it 
requires development effort.  
D. AIOps integrated into HPE Aruba Networking Central: Aruba Central's AIOps capabilities are 
specifically designed to enhance visibility and automate aspects of troubleshooting. It uses AI
/ML to analyze network data, detect anomalies, provide insights into potential issues, correlate 
events, and offer prescriptive recommendations, directly addressing the client's need for better 
visibility and automated assistance with troubleshooting.  
Conclusion:While custom scripting (C) allows automation, Aruba Central AIOps (D) is the platform-
integrated solution specifically marketed and designed by HPE Aruba Networking to provide enhanced 
visibility and automated insights fortroubleshooting campus networks. It is the most direct and 
recommended solution among the options for achieving these goals within the Aruba ecosystem.

9 of 16Verified Solution - 100% Result
D. The edge switch acts as the intermediate node and transfers the Group Policy ID over static VXLAN to 
dynamic VXLAN tunnel and forwards the packet to switch Al.
Answer: A
Explanation
The question asks for the fourth step in applying a role-to-role ACL on traffic from a mobile device (M1) to a 
role (H2) in a network using Dynamic Segmentation with VXLAN. This follows question 17, which 
identified the first step as the AP forwarding the packet to the gateway.
Analysis of Options:
Option A:Correct. The fourth step involves the destination switch (Switch A1) determining the 
destination role (H2) based on the destination MAC or IP address and applying the role-to-role 
ACL to permit or deny the traffic.
Option B:Describes an earlier step (likely second or third) where the gateway forwards traffic 
over a VXLAN tunnel.
Option C:Describes the first step, as identified in question 17.
Option D:Describes an intermediate step (likely third) where the edge switch transfers the Group 
Policy ID over VXLAN.
Why Option A is Correct:In HPE Aruba Networking’s Dynamic Segmentation architecture, the traffic 
flow for role-based ACLs in a VXLAN environment follows these steps:
The AP forwards the packet from M1 to the gateway (question 17).
The gateway assigns the source role (M1’s role) and forwards the packet over a VXLAN tunnel 
with the Group Policy ID.
The edge switch transfers the Group Policy ID to the destination switch (A1) via VXLAN.
Switch A1 determines the destination role (H2) based on the destination MAC or IP address and 
enforces the role-to-role ACL, as defined in the Group-Based Policy (GBP).
The fourth step is critical for policy enforcement, ensuring that traffic complies with the security policies 
defined between the source and destination roles, providing secure network segmentation.
Relevance to Certification Objectives:
Security (10%):Designing and troubleshooting role-based security policies in customer networks.
Switching (19%):Implementing Layer 2/3 interconnection technologies like VXLAN for policy 
enforcement.

Question #:7 - [Switching]
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.

D. 
port-access onboarding-method concurrent enable
port access role Access_point
auth-mode device-mode
Answer: B
Explanation
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 settingaaa 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.

Option D (diag cable 1/1/X):Incorrect; “diag cable” is not a valid AOS-CX command.
Option E (diag 1/1/X transceiver all):Correct. This command displays detailed transceiver 
information, including status, errors, and signal quality, useful for diagnosing interface issues.
Why C and E are Correct:The diag cable-diagnostic 1/1/X command is used to perform TDR tests to 
identify cable faults, which could cause connectivity issues. The diag 1/1/X transceiver all command 
provides detailed transceiver diagnostics, such as power levels, errors, or hardware issues, helping 
pinpoint problems with the interface or connected device. These commands align with AOS-CX 
troubleshooting workflows for physical layer issues.
Relevance to Certification Objectives:
Troubleshooting (10%):Involves using diagnostic commands to troubleshoot campus network 
issues.
Connectivity (9%):Includes identifying problem areas in device deployment, such as cabling or 
transceiver issues.

D. 
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.
Answer: C
Explanation
The scenario describes two separate VSX clusters interconnected via MC-LAG, where both clusters are 
configured to use the virtual IP address and virtual MAC address for their respective Active exact same
Gateway SVIs.
Active Gateway Scope & Conflict:Active Gateway provides a highly available default gateway a within
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

A. 
B. 
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.

HTTPS Server : sw_image_version_mismatch_error  
Primary Software Version: GL.10.09.0010  
Secondary Software Version: GL.10.11.1021  
These errors clearly indicate that the primary and secondary VSX switches are running different AOS-CX 
software versions. For VSX to operate correctly, including configuration synchronization and enabling 
features like MC-LAG interfaces, both switches in the pair run the exact same software version.must
Analysis of Options:
A: vsx-software-upgrade is used for upgrades but doesn't resolve the current mismatch 
requirement.
B: NAE errors are a symptom of the underlying version mismatch.
C: Using the same CX OS version on both primary and secondary switches is the fundamental 
requirement to clear the mismatch errors and achieve a stable VSX operational state.
D: While ServiceOS is part of the system, the primary requirement and error message relate to 
the main AOS-CX software version.
