Refer to the exhibit which illustrates the current configuration of Router-1. Clients of VLAN 10 require access to services hosted in the 10.1.100.0/24subnet. This 'equites one 01 more routes to be added to Rculer-1 that do not currently exist. Which script would install a route from 10.2.10.0/24 to 10.1.100.0/24 on Router-1? A return path is not required as part of this answer.
Correct Answer: D
The goal is to add a static route on Router-1 to allow clients in VLAN 10 (subnet 10.2.10.0/24, presumably in VRF 'IoT-Medical' based on options) to reach services in the 10.1.100.0/24 subnet. The exhibit indicates interface 1/1/1 (IP 10.255.101.10/24) is in VRF 'service', and the likely next hop towards the destination is Core-1 at 10.255.101.11 (also implied to be reachable via VRF 'service'). This requires adding a route in the source VRF ('IoT-Medical') pointing towards the destination via the next hop in the 'service' VRF. * Static Route Syntax (with VRF):ip route <destination_prefix> <next-hop-ip> [vrf <source-vrf>] * Analysis of Options: * A: Claims Core-1 isn't in VRF 'service', contradicting the likely setup. * B: Uses unusual interface:ip syntax (1/1/1:10.255.101.11). Defines the route in VRF 'IoT- Medical'. * C: Uses interface 1/1/1 as the next hop. This is less specific than using the IP address and relies on the interface being point-to-point or having proxy ARP enabled. Defines the route in VRF 'IoT-Medical'. * D: ip route 10.1.100.0/24 10.255.101.11 vrf IoT-Medical. This uses the standard syntax to define a static route for the destination 10.1.100.0/24 via the next-hop IP 10.255.101.11 within the context of the IoT-Medical VRF. The successful function of this route depends on inter-VRF routing (route leaking) being configured between 'IoT-Medical' and 'service' VRFs, but the command itself correctly defines the desired static route. * Conclusion:Option D provides the correct and standard command syntax to configure the required static route within the specified source VRF ('IoT-Medical').

Question 2
Youare configuring an HPE Aruba NetworkingGateway Ouster with AOS-10. What is true about 802.1 X functionality incombination with gateways? (Select two.)
Correct Answer: B,D
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. References:Aruba AOS-10 documentation (Gateway Clusters, User-Based Tunneling, 802.1X/RADIUS interaction, L2/L3 Mobility).

Question 3
Exhibit.
Correct Answer: C
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 <transit-area> virtual-link <router-id> 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 <transit-area> virtual-link <remote-router-id> 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 4
Which setof commands willapply the device profile 'AP'to the device shown in the LLDP neighbor output below?
Correct Answer: A
The goal is to configure the switch to automatically apply a specific device profile (named AP-PROFILE in the options) to ports where an Aruba AP Model 635 connects, using LLDP information for detection. * LLDP Information:The LLDP neighbor output shows: * Neighbor Chassis-Description: ArubaOS (MODEL: 635), Version Aruba AP * Neighbor Chassis-Name: AP-42 * Device Profile Mechanism:This involves creating an LLDP group that matches specific attributes of the desired device, creating a device profile containing the desired port configurations (VLAN, PoE, QoS, Role, etc.), associating the profile with the LLDP group, and enabling the feature globally. * Analyzing Configuration Options:All options configure an LLDP group AP-LLDP-GROUP and a device profile AP-PROFILE. The key is the matching condition within the LLDP group and the completeness of the profile configuration. * Matching Condition: * Options A, C, D use seq 10 match sys-desc 635. This condition checks if the LLDP System Description contains the string "635". Based on the output (...MODEL: 635...), this conditionwill matchthe target AP. * Option B uses seq 10 match sys-name 635. This checks if the LLDP System Name contains "635". The output shows Neighbor Chassis-Name: AP-42. This conditionwill not match.
Question 5
A client is unable to connect to the network, In the HPE Aruba Networking ClearPass access tracker, wo can seean EAP timeout What is a possible cause of this message?
Correct Answer: D
The question involves an EAP timeout in HPE Aruba Networking ClearPass Access Tracker during an 802.1 X authentication attempt, with the task of identifying a possible cause. * Analysis of Options: * Option A:Incorrect. A client certificate trust issue would cause a different error, not an EAP timeout. * Option B:Incorrect. An expired client certificate would result in an authentication failure, not a timeout. * Option C:Incorrect. If the client sees an expired RADIUS server certificate, it would reject it, but this typically causes a trust error, not a timeout. * Option D:Correct. If the client does not trust the RADIUS server's certificate (e.g., missing CA certificate or untrusted issuer), it may fail to proceed with the EAP handshake, leading to an EAP timeout. * Why Option D is Correct:In 802.1X authentication with EAP (e.g., EAP-TLS or EAP-PEAP), the client must trust the RADIUS server's certificate to establish a secure TLS tunnel. If the client's trust store lacks the Certificate Authority (CA) certificate or the server's certificate is untrusted (e.g., self- signed without proper installation), the clientaborts the EAP handshake, resulting in an EAP timeout logged in ClearPass. This is a common issue in 802.1X deployments and can be resolved by ensuring the client has the correct CA certificate or by using a trusted server certificate, as per HPE Aruba Networking's security guidelines. * Relevance to Certification Objectives: * Authentication/Authorization (9%):Troubleshooting 802.1X and ClearPass authentication issues. * Security (10%):Diagnosing wired 802.1X with EAP-TLS failures. * Troubleshooting (10%):Resolving authentication timeouts in campus networks.
