Your customer has four (4) Aruba 7200 Series Gateways and two (2) 7000 Series Gateways. The customer wants to form a cluster with these Gateways.
What design consideration would prevent you from using all of those Gateways?
- A . Multiple versions between Gateways in the same cluster profile are not allowed AOS 10.x.
- B . A heterogeneous cluster is not supported in AOS 10.x.
- C . The AP load should be lowest value of worst-case scenario load.
- D . A combination of 7200 series and 7000 series gateways supports up to 4 nodes
B
Explanation:
The reason is that AOS 10.x does not support clustering gateways with different versions in the same cluster profile. A cluster profile defines the configuration settings for a group of gateways that are managed by Aruba Central.
According to the Aruba documentation2, "You can combine 7200 Series and 7000 Series gateways in the same cluster with a maximum size of four devices with reduced AP client capacity on 7000 Series gateways."
Review the exhibit.
You are troubleshooting an issue with a 10 102.39 0/24 subnet which is also VLAN 1000 used Tor wireless clients on a pair of Aruba CX 8360 switches The subnet SVI is configured on the 8360 pair, and the DHCP server is a Microsoft Windows Server 2022 Standard with an IP address of 10 200 1.100. The 10.102.250.0/24 subnet is used for switch management.
A large number of DHCP requests are failing You are observing sporadic DHCP behavior across clients
attached to the CX 6100 switch.
Which action may help fix the issue?
A)
B)
C)
D)
- A . Option A
- B . Option B
- C . Option C
- D . Option D
C
Explanation:
Option B is the correct action that may help fix the issue of sporadic DHCP behavior across clients attached to the CX 6100 switch. Option B enables DHCP relay on VLAN 1000 interface on Core-1 switch, which allows DHCP requests from clients in VLAN 1000 to be forwarded to the DHCP server in a different subnet (10.200.1.100). Without DHCP relay, clients in VLAN 1000 cannot obtain IP addresses from the DHCP server because they are in different broadcast domains. The other options are incorrect because they either do not enable DHCP relay or do not configure it correctly.

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
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.

A company recently deployed new Aruba Access Points at different branch offices Wireless 802.1X authentication will be against a RADIUS server in the cloud. The security team is concerned that the traffic between the AP and the RADIUS server will be exposed..
What is the appropriate solution for this scenario?
- A . Enable EAP-TLS on all wireless devices
- B . Configure RadSec on the AP and Aruba Central.
- C . Enable EAP-TTLS on all wireless devices.
- D . Configure RadSec on the AP and the RADIUS server
D
Explanation:
This is the appropriate solution for this scenario where wireless 802.1X authentication will be against a RADIUS server in the cloud and the security team is concerned that the traffic between the AP and the RADIUS server will be exposed. RadSec, also known as RADIUS over TLS, is a protocol that provides encryption and authentication for RADIUS traffic over TCP and TLS. RadSec can be configured on both the AP and the RADIUS server to establish a secure tunnel for exchanging RADIUS packets. The other options are incorrect because they either do not provide encryption or authentication for RADIUS traffic or do not involve RadSec.

What is the primary purpose of implementing Aruba’s Dynamic Segmentation?
- A . To segregate network traffic based on VLAN IDs
- B . To provide robust network security at the edge
- C . To apply user roles dynamically across wired and wireless networks
- D . To reduce the complexity of VLAN configurations
What is an Aruba-recommended best practice for hardening that only applies to Aruba CX 6300 series switches with dedicated management ports?
- A . Implement a control plane ACL to limit access to approved IPs and/or subnets
- B . Manually enable Enhanced Security Mode from a console session.
- C . Disable all management services on the default VRF.
- D . Create a dedicated management VRF, and assign the management port to it.
D
Explanation:
This is an Aruba-recommended best practice for hardening that only applies to Aruba CX 6300 series switches with dedicated management ports. A dedicated management port is a physical port that is used exclusively for out-of-band management access to the switch. A dedicated management VRF is a virtual routing and forwarding instance that isolates the management traffic from other traffic on the switch. By creating a dedicated management VRF and assigning the management port to it, the administrator can enhance the security and performance of the management access to the switch. The other options are incorrect because they either do not apply to switches with dedicated management ports or do not follow Aruba-recommended best practices.

What is a primary benefit of BSS coloring?
- A . BSS color tags improve performance by allowing clients on the same channel to share airtime.
- B . BSS color tags are applied to client devices and can reduce the threshold for interference
- C . BSS color tags are applied to Wi-Fi channels and can reduce the threshold for interference
- D . BSS color tags improve security by identifying rogue APs and removing them from the network.
A customer is using a legacy application that communicates at layer-2. The customer would like to keep this application working across the campus which is connected via layer-3. The legacy devices are connected to Aruba CX 6300 switches throughout the campus.
Which technology minimizes flooding so the legacy application can work efficiently?
- A . Generic Routing Encapsulation (GRE)
- B . EVPN-VXLAN
- C . Ethernet over IP (EolP)
- D . Static VXLAN
B
Explanation:
EVPN-VXLAN is a technology that allows layer-2 communication across layer-3 networks by using Ethernet VPN (EVPN) as a control plane and Virtual Extensible LAN (VXLAN) as a data plane3. EVPN-VXLAN can be used to support legacy applications that communicate at layer-2 across different campuses or data centers that are connected via layer-3. EVPN-VXLAN minimizes flooding by using BGP to distribute MAC addresses and IP addresses of hosts across different VXLAN segments3. EVPN-VXLAN also provides benefits such as loop prevention, load balancing, mobility, and scalability3.

Your customer is having connectivity issues with a newly-deployed Microbranch group The access points in this group are online in Aruba Central, but no VPN tunnels are forming..
What is the most likely cause of this issue?
- A . There is a time difference between the AP and the gateways The gateways should have NTP added
- B . The SSL certificate on the gateway used to encrypt the connection has not been added to the APs trust list
- C . There may be a firewall blocking GRE tunneling between the AP and the gateway
- D . The gateway group is running in automatic cluster mode and should be in manual cluster mode
C
Explanation:
This is the most likely cause of the issue where the access points in a Microbranch group are online in Aruba Central, but no VPN tunnels are forming. A Microbranch group is a group that contains both APs and Gateways and allows them to form VPN tunnels for secure communication. The VPN tunnels use GRE (Generic Routing Encapsulation) as the encapsulation protocol and IPSec as the encryption protocol. If there is a firewall blocking GRE traffic between the AP and the gateway, the VPN tunnels cannot be established. The other options are incorrect because they either do not affect the VPN tunnel formation or do not apply to a Microbranch group.

On AOS10 Gateways, which device persona is only available when configuring a Gateway-only group’?
- A . Edge
- B . Mobility
- C . Branch
- D . VPN Concentrator
D
Explanation:
VPN Concentrator is the device persona that is only available when configuring a Gateway-only group on AOS10 Gateways. A device persona defines the role and functionality of a Gateway in a network. A Gateway-only group is a group that contains only Gateways and no APs. A VPN Concentrator persona enables a Gateway to terminate VPN tunnels from remote APs or clients and provide secure access to corporate resources. The other options are incorrect because they are either not device personas or not exclusive to Gateway-only groups.
