Question #31
A customer is looking Tor a wireless authentication solution for all of their loT devices that meet the following requirements
– The wireless traffic between the IoT devices and the Access Points must be encrypted
– Unique passphrase per device
– 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
Correct Answer: A C
A C
Explanation:
MPSK is a feature that allows device-specific or group-specific passphrases for WPA2 PSK-based deployments. The passphrases are generated by a RADIUS server such as ClearPass Policy Manager and sent to the APs. The wireless traffic between the IoT devices and the APs is encrypted using the passphrases. The passphrases can also be used to perform role-based access by mapping them to different VLANs and user roles 12. ClearPass Policy Manager is a network access control solution that can provide device fingerprinting and profiling for IoT devices based on various attributes such as MAC address, DHCP options, HTTP user agents, etc3. ClearPass Policy Manager can also integrate with other IoT platforms and services to enhance the visibility and security of IoT devices.

Question #32
Which method is used to onboard a new UXI in an existing environment with 802.1X authentication? (The sensor has no cellular connection)
- A . Use the UXI app on your smartphone and connect the UXI via Bluetooth
- B . Connect the new UXI from an already installed one and adjust the initial configuration.
- C . Use the Aruba installer app on your smartphone to scan the barcode
- D . Use the CLI via the serial cable and adjust the initial configuration.
Correct Answer: A
A
Explanation:
To onboard a new UXI in an existing environment with 802.1X authentication, you need to use the UXI app on your smartphone and connect the UXI via Bluetooth. The UXI app allows you to scan the QR code on the UXI sensor and configure its network settings, such as SSID, password, IP address, etc.
The Bluetooth connection allows you to communicate with the UXI sensor without requiring any network access or cellular connection. The other options are incorrect because they either do not use the UXI app or do not use Bluetooth.

Question #33
You need to create a keepalive network between two Aruba CX 8325 switches for VSX configuration How should you establish the keepalive connection?
- A . SVI, VLAN trunk allowed all on ISL in default VRF
- B . routed port in custom VRF
- C . loopback 0 and OSPF area 0 in default VRF
- D . SVI, VLAN trunk allowed all on ISL in custom VRF
Correct Answer: B
B
Explanation:
To establish a keepalive connection between two Aruba CX 8325 switches for VSX configuration, you need to use a routed port in custom VRF. A routed port is a physical port that acts as a layer 3 interface and does not belong to any VLAN. A custom VRF is a virtual routing and forwarding instance that provides logical separation of routing tables. By using a routed port in custom VRF, you can isolate the keepalive traffic from other traffic and prevent routing loops or conflicts. The other options are incorrect because they either do not use a routed port or do not use a custom VRF.

Correct Answer:
Question #35
With the Aruba CX 6200 24G switch with uplinks or 1/1/25 and 1/1/26, how do you protect client ports from forming layer-2 loops?
- A . int 1/1/1-1/1/24, loop-protect
- B . int 1/1/1-1/1/28. loop-protect
- C . int 1/1/1-1/1/28. loop-guard
- D . int 1/1/1-1/1/24. loop-guard
Correct Answer: A
A
Explanation:
The command loop-protect enables loop protection on each layer 2 interface (port, LAG, or VLAN) for which loop protection is needed. Loop protection can find loops in untagged layer 2 links, as well as on tagged VLANs.

Question #37
You need lo have different routing-table requirements with Aruba CX 6300 VSF configuration Assuming the correct layer-2 VLAN already exists how would you create a new OSPF configuration for a separate routing table?
- A . Create a new OSPF area, and attach VRF name.
- B . Create a new OSPF process ID with vrf name.
- C . Attach a new OSFP process ID with a custom routing table
- D . Attach OSPF process ID in the VRF configuration.
Correct Answer: B
B
Explanation:
To create a new OSPF configuration for a separate routing table, you need to create a new OSPF process ID with vrf name. This will create a new OSPF instance that is associated with the specified VRF and its routing table. The other options are incorrect because they either do not create a new OSPF instance or do not associate it with a VRF.

Question #38
The customer needs a network hardware refresh to replace an aging Aruba 5406R core switch pair using spanning tree configuration with Aruba CX 8360-32YC switches.
What is the benefit of VSX clustering with the new solution?
- A . stacked data-plane
- B . faster MSTP converge processing
- C . dual Aruba AP LAN port connectivity for PoE redundancy
- D . dual control plane provides better resiliency
Correct Answer: D
D
Explanation:
VSX clustering is a feature that allows two Aruba CX switches to operate as a single logical device, providing high availability, scalability, and simplified management.
VSX clustering has several benefits over spanning tree configuration, such as:
* Dual control plane provides better resiliency. Unlike stacking, where switches share a single control plane, VSX switches have independent control planes that synchronize their states over an inter-switch link (ISL). This means that if one switch fails or reboots, the other switch can continue to operate without affecting traffic flows or network services.
* Active-active forwarding provides better performance. Unlike spanning tree, where some links are blocked to prevent loops, VSX switches use all available links for forwarding traffic, providing load balancing and increased bandwidth utilization.
* Multichassis LAG provides better redundancy. Unlike single-chassis LAG, where all member ports belong to one switch, VSX switches can form multichassis LAGs with downstream or upstream devices, where member ports are distributed across both switches. This provides link redundancy and seamless failover in case of switch or port failure.
