  Explanation

  These are two correct statements regarding OSPFv2 route redistribution for Aruba OS CX switches. Route redistribution is a process that allows routes from one routing protocol or source to be injected into another routing protocol or destination. OSPFv2 is a link-state routing protocol that supports route redistribution from various sources, such as connected, static, BGP, etc. The "redistribute connected" command will redistribute all connected routes for the switch, including local loopback addresses, into OSPFv2. The "redistribute static route-map connected-routes" command will redistribute all static routes that have a matching permit statement in the route map named "connected- routes" into OSPFv2. The other statements are incorrect because they either do not reflect the correct behavior of route redistribution commands or do not exist as valid commands.

• Question 3:

  Your manufacturing client is deploying twenty headless scanners in their warehouse.

  These new devices do not support 802.1X authentication.

  How does the gateway determine the device's role and VLAN derivation-rules when using MPSK Local?

  A. From the Type-Length-Value based on the Aruba-MPSK-Key-Name.
  B. It pulls the device roles from HPE Aruba Networking Central during deployment.
  C. From the device's Calling-Station-ID in the RADIUS Access-Request.
  D. From the MPSK roles defined in HPE Aruba Networking Central's security dashboard.
  A. From the Type-Length-Value based on the Aruba-MPSK-Key-Name.

• Question 4:

  You are proposing new CX 8360 VSX switches to replace a customer's existing core switches.

  The customer is concerned about the possibility of a split-brain scenario between the VSX pair.

  How is the VSX pair affected when the ISL is down and keepalive is up?

  A. The VSX pair is out-of-sync.
  B. The VSX pair nodes are still forwarding traffic.
  C. The VSX LAGs are in a degraded state.
  D. The VSX pair is not at risk.
  D. The VSX pair is not at risk.

• Question 5:

  A customer is using a legacy application that communicates at layer-2. The customer would like to keep this application working to a remote site connected via layer-3 All legacy devices are connected to a dedicated Aruba CX 6200 switch at each site.

  What technology on the Aruba CX 6200 could be used to meet this requirement?

  A. Inclusive Multicast Ethernet Tag (IMET)
  B. Ethernet over IP (EolP)
  C. Generic Routing Encapsulation (GRE)
  D. Static VXLAN
  A. Inclusive Multicast Ethernet Tag (IMET)

  ---

  Explanation

  VXLAN is a technology that can be used to meet the requirement of using a legacy application that communicates at layer-2 across a layer-3 network. Static VXLAN is a feature that allows the creation of layer-2 overlay networks over a layer- 3 underlay network using VXLAN tunnels. Static VXLAN does not require any control plane protocol or VTEP discovery mechanism, and can be configured manually on the Aruba CX 6200 switches. The other options are incorrect because they either do not support layer-2 communication over layer-3 network or are not supported by Aruba CX 6200 switches.

• Question 6:

  Which Aruba AP mode is sending captured RF data to Aruba Central for waterfall plot?

  A. Hybrid Mode
  B. Air Monitor
  C. Spectrum Monitor
  D. Dual Mode
  C. Spectrum Monitor

  ---

  Explanation

  Spectrum Monitor is an Aruba AP mode that is sending captured RF data to Aruba Central for waterfall plot. Spectrum Monitor is a mode that allows an AP to scan all channels in both 2.4 GHz and 5 GHz bands and collect information about the RF environment, such as interference sources, noise floor, channel utilization, etc. The AP then sends this data to Aruba Central, which is a cloud-based network management platform that can display the data in various formats, including waterfall plot. Waterfall plot is a graphical representation of the RF spectrum over time, showing the frequency, amplitude, and duration of RF signals. The other options are incorrect because they are either not AP modes or not sending RF data to Aruba Central.

• Question 7:

  A customer is looking Tor a wireless authentication solution for all of their loT devices that meet the following requirements

  1. The wireless traffic between the IoT devices and the Access Points must be encrypted

  2. Unique passphrase per device

  3. Use fingerprint information to perform role-based access

  Which solutions will address the customer's requirements? (Select two.)

  A. MPSK and an internal RADIUS server
  B. MPSK Local with MAC Authentication
  C. ClearPass Policy Manager
  D. MPSK Local with EAP-TLS
  E. Local User Derivation Rules
  C. ClearPass Policy Manager
  D. MPSK Local with EAP-TLS

  ---

  Explanation

  The correct answers are C and D.

  MPSK (Multi Pre-Shared Key) is a feature that allows multiple PSKs to be used on a single SSID, providing device-specific or group-specific passphrases for enhanced security and deployment flexibility for headless IoT devices 1. MPSK requires MAC authentication against a ClearPass Policy Manager server, which returns the encrypted passphrase for the device in a RADIUS VSA2. ClearPass Policy Manager is a platform that provides role- and device-based network access control for any user across any wired, wireless and VPN infrastructure 3. ClearPass Policy Manager can also use device profiling and posture assessment to assign roles based on device fingerprint information 4. MPSK Local is a variant of MPSK that allows the user to configure up to 24 PSKs per SSID locally on the device, without requiring ClearPass Policy Manager5. MPSK Local can be combined with EAP-TLS (Extensible Authentication Protocol-Transport Layer Security), which is a secure authentication method that uses certificates to encrypt the wireless traffic between the IoT devices and the access points 6. EAP-TLS can also use device certificates to perform role-based access control 6.

  Therefore, both ClearPass Policy Manager and MPSK Local with EAP-TLS can meet the customer's requirements for wireless authentication, encryption, unique passphrase, and role-based access for their IoT devices.

  MPSK and an internal RADIUS server is not a valid solution, because MPSK does not support internal RADIUS servers and requires ClearPass Policy Manager789. MPSK Local with MAC Authentication is not a valid solution, because MAC Authentication does not encrypt the wireless traffic or use fingerprint information for role-based access 2. Local User Derivation Rules are not a valid solution, because they do not provide unique passphrase per device or use fingerprint information for role-based access101112.

• Question 9:

  You are working on a network where the customer has a dedicated router with redundant Internet connections Tor outbound high-importance real-time audio streams from their datacenter All of this traffic.

  originates from a single subnet uses a unique range of UDP ports is required to be routed to the dedicated router

  All other traffic should route normally. The SVI for the subnet containing the servers originating the traffic is located on the core routing switch in the datacenter.

  What should be configured?

  A. Configure a new OSPF area including both the core routing switch and the dedicated router
  B. Configure a BGP link between the core routing switch and the dedicated router and route filtering.
  C. Configure Policy Based Routing (PBR) on the core routing switch for the VRF with the servers' SVI
  D. Configure a dedicated VRF on the core routing switch and make the dedicated router the default route.
  C. Configure Policy Based Routing (PBR) on the core routing switch for the VRF with the servers' SVI

  ---

  Explanation

  The reason is that PBR allows you to route packets based on policies that match certain criteria, such as source or destination IP addresses, ports, protocols, etc. PBR can also be used to set metrics, next-hop addresses, or tag traffic for different routes.

• Question 10:

  A customer wants to find wireless clients indoors with meter-level accuracy by using supported Aruba APs as responders.

  Which IEEE standard enables this capability?

  A. 802.11r
  B. 802.11mc
  C. 802.11k
  D. 802.11w
  B. 802.11mc

  ---

  Explanation

  802.11mc is the correct standard because it enables Fine Timing Measurement (FTM), which uses round-trip timing to estimate distance between the client and nearby APs. With multiple AP measurements, the client location can be calculated with much greater precision than conventional RSSI-based methods. 802.11r is related to fast transition roaming, 802.11k is related to radio resource measurements, and 802.11w protects certain management frames. None of those standards provide the same RTT/ FTM-based positioning function.
