NO.39 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.

NO.40 You want to use OSPF to advertise a only .16 summary route for the SVlsbelow to a neighbor In the same area (area 0).
Which configuration will achieve this?

The goal is to configure OSPF on a router so that it advertisesonlya 10.1.0.0/16 summary route for the specific SVIs (VLAN 11, 12, 13, assumed to be within the 10.1.x.x range) to its OSPF neighborswithin the same area (Area 0).
* OSPF Intra-Area Behavior:A fundamental principle of OSPF (link-state protocols) is that all routers within the same area must have an identical Link State Database (LSDB) for that area. This means all routers learn about all the specific networks (Type-1 Router LSAs, Type-2 Network LSAs) within their area. OSPFv2 doesnotsupport summarizing routes in a way that hides specific network LSAs from other routerswithin the same area. Summarization occurs only at area boundaries (by ABRs using Type-
3 Summary LSAs via the area range command) or for external routes redistributed into OSPF (by ASBRs using Type-5 External LSAs via the summary-address command).
* Analysis of Options:
* A) area 0 range 10.1.0.0/16:This command is used on an Area Border Router (ABR) to summarize routes originatingfromArea 0 when advertising theminto another area(e.g., the backbone). It does not affect LSA floodingwithinArea 0. It also includes redistribute connected, which is unrelated here.
* B) summary-address 10.1.0.0/16:This command is used on an Autonomous System Boundary Router (ASBR) to summarizeexternalroutes being redistributed into OSPF. It is not used for summarizing internal OSPF routes like SVIs defined within an OSPF area.
* C) & D) summary-address 10.1.0.0/16:Same issue as B; incorrect command for summarizing internal OSPF routes.
* E) area 0 range 10.1.0.0/16:Similar to A, this uses the area range command. It correctly shows the SVIs configured for OSPF Area 0 first. However, like A, this command performs inter-area summarization on an ABR and does not suppress the specific LSAswithinArea 0.
* Conclusion:The question asks for something that OSPFv2 cannot do: advertiseonlya summary route within the same area while suppressing specifics. Therefore, none of the configurations will achieve the exactstated outcome. However, if the question is flawed and intends to ask which configuration uses the correct command structure for summarizinginternalOSPF routes (even if only effective between areas), then the area range command is the relevant one. Both A and E use this command. Option E is slightly better structured as it shows the interfaces being added to OSPF Area 0 first. Assuming this is the intended direction despite the impossibility of the specific request, E is the most plausible choice among the given options.

NO.42 Match the BGP connection states to the conditions that could have caused that state.

Explanation:
The last keepalive is less than 3 times the negotiated holddown timer. –>established The router has not received a response. The neighbor might be unreachable. –>active The router is waiting for an initial response from the neighbor. –>connect The router starts listening for a connection. –>idle This question requires matching specific BGP connection states from the BGP Finite State Machine (FSM) to descriptions of the router’s activity or condition in those states.
* Idle:This is the starting state. The BGP process is administratively up but is not actively trying to connect. It refuses all incoming BGP connection attempts but listens for a start event (like configuration or operator initiation) or potentially listens for incoming connections if configured for passive peering.
* Matches:”The router starts listening for a connection.” (This describes the passive aspect of the Idle state before active attempts begin).
* Connect:In this state, BGP is actively trying to establish a TCP connection with the peer. It has initiated the TCP three-way handshake and is waiting for it to complete, or it is waiting for a remote peer to initiate the TCP connection.
* Matches:”The router is waiting for an initial response from the neighbor.” (Specifically, waiting for the TCP handshake to complete).
* Active:If the TCP connection attempt in the Connect state fails (e.g., timeout), the router transitions to the Active state. In this state, it will periodically retry establishing the TCP connection while also listening for an incoming connection from the peer. This state indicates repeated failures to establish TCP connectivity.
* Matches:”The router has not received a response. The neighbor might be unreachable.” (This reflects the condition in the Active state where connection attempts fail, suggesting the neighbor is unreachable at the TCP level).
* Established:This is the final, operational state where the TCP connection is up, BGP session parameters have been successfully negotiated via OPEN messages, and KEEPALIVE messages are being exchanged. Routing information (UPDATEs) can be exchanged. The condition described implies the session is healthy and timers are being maintained.
* Matches:”The last keepalive is less than 3 times the negotiated holddown timer.” (While phrased slightly unusually, this indicates the holddown timer hasnotexpired because keepalives are being received within the expected window (Holddown Timer = ~3 * Keepalive Interval). This confirms the session is alive, which is true in the Established state).

NO.44 Review the diagram and existing configuration of RouterA above. Which configuration changes are necessary to permit load balancing between RouterA and RouterB? (Selecttwo) Exhibit.

NO.45 You are configuring an SSID that is using PSK as a security mechanism. Why should you use WPA3- Personal with WPA3 Transition Mode disabled?

WPA3-Porsonal with Transition Modedisabled is optional tor 6 GHz-enabled networks as there is a built-in tailback to 6 GHz mode with WPA2

WPA3-Personal with Transition Mode disabled is mandatory for 6 GHz-enabled networks.

WPAS-Personalwith Transition Mods disabled is mandatory for 5 GHz-enabled networks.

WPA3-Porsonal with Transition Mode disabled should be used to prevent legacy clients from connecting to thenetwork.

NO.46 You are configuring an SSID thatisusing 802.IX as a security mechanism. Whatis the reason tor using WPA3- Ertorpnse (CCM-128) when deploying Wi-Fi 6 networks?

WPA3-Entorprise(CCM-128) is also called WPA3-Entorpnso 192-bit mode. lt is WPA3 only and enforces specific EAP certificate ciphers.

WPA3-Enterprise (CCM-128) is also called WPA3-Ente’prise Transition Mode. It will allow WPA2 clients to conned.

WPA3-Enterprise(CCM-128) is also called WPA3-Eniarpnse Compatibility Mode. It will allow WPA2 clients to connect.

WPA3-Enterprise(CCM-128) is also called WPA3-EnterpriseOnly Mode. There is no support tor WPA2 clients.

NO.47 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.

NO.49 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.

NO.50 You are configuring VSX active gateway on CX 8360 campus aggregation switches when the switch prompt returns the following error: “No more than IB VMACs can be configured.” What should be done to address this issue?

Limit the number of SVIs with active-gatewayto 16.

Change the switch profile to ”Leal” to increase the number of supported vMACs.

Change the aggregation switch to a higher-end model, such as a CX 8400.

As MAC addresses are link-local, use the same VMAC across SVIs.

NO.51 Which command will permit read-only access to a user with physical access to an AOS-CS switch?
