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.
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.

Your customer has asked you to assign a switch management role for a new user The customer requires the user role to only have Web Ul access to the System > Log page and only have access to the GET method for REST API for the /logs/event resource
Which default AOS-CX user role meets these requirements?
- A . administrators
- B . auditors
- C . sysops
- D . operators
B
Explanation:
The auditors role is the default AOS-CX user role that meets the requirements of having Web UI access to the System > Log page and having access to the GET method for REST API for the /logs/event resource. The auditors role has a level of 1 and allows read-only access to most commands except those related to security or passwords. It also allows access to the Web UI and REST API with limited permissions. The other options are incorrect because they either have higher levels of access or do not allow access to the Web UI or REST API.

Using Aruba best practices what should be enabled for visitor networks where encryption is needed but authentication is not required?
- A . Wi-Fi Protected Access 3 Enterprise
- B . Opportunistic Wireless Encryption
- C . Wired Equivalent Privacy
- D . Open Network Access
B
Explanation:
Opportunistic Wireless Encryption (OWE) is a feature that provides encryption for open wireless networks without requiring authentication. OWE uses an enhanced version of the 4-way handshake to establish a pairwise key between the client and the AP, which is then used to encrypt the wireless traffic using WPA2 or WPA3 protocols. OWE can be used for visitor networks where encryption is needed but authentication is not required.

A network administrator is attempting to troubleshoot a connectivity issue between a group of users and a particular server The administrator needs to examine the packets over a period of time from their desktop; however, the administrator is not directly connected to the AOS-CX switch involved with the traffic flow.
What statements are correct regarding the ERSPAN session that needs to be established on an AOS-CX switch’? (Select two )
- A . On the source AOS-CX switch, the destination specified is the switch to which the administrator’s desktop is connected
- B . The encapsulation protocol used is GRE.
- C . The encapsulation protocol used is VXLAN.
- D . The encapsulation protocol is UDP.
- E . On the source AOS-CX switch, the destination specified is the administrators desktop
B E
Explanation:
These are the correct statements regarding the ERSPAN session that needs to be established on an AOS-CX switch for a network administrator to examine the packets over a period of time from their desktop. ERSPAN (Encapsulated Remote Switched Port Analyzer) is a feature that allows an AOS-CX switch to mirror traffic from one or more source ports or VLANs to a remote destination IP address over a GRE (Generic Routing Encapsulation) tunnel. The destination IP address must be the IP address of the administrator’s desktop, which must have a packet capture tool installed to receive and analyze the mirrored traffic. The encapsulation protocol used for ERSPAN is GRE, which adds a header to the mirrored packets with information such as source and destination IP addresses, session ID, etc.
The other statements are incorrect because they either do not specify the correct destination IP address or do not use ERSPAN or GRE.

Match the appropriate QoS concept with its definition. (Options may be used more than once or not at all.)
Explanation:
QoS concept: Class of Service Definition: 3) A method for classifying network traffic using access categories based on the IEEE 802.11e QoS standards QoS concept: Differentiated services Definition: 2) A method for classifying network traffic at layer-3 or marking packets with one of 64 different service classes QoS concept: WMM Definition: 4) A method for classifying network traffic using access categories based on the IEEE 802.11e QoS standards
What are the requirements to ensure that WMM is working effectively’? (Select two)
- A . The APs and the controller are Wi-Fi CERTIFIED for WMM which is enabled
- B . All APs need to be from the AP-5xx series and AP-6xx series which are Wi-Fi CERTIFIED 6.
- C . The Client must be Wi-Fi CERTIFIED for WMM and configured for WMM marking.
- D . The Aruba AOS10 APs installed have to be converted to controlled mode
- E . The AP needs to be connected via a tagged VLAN to the wired port
A C
Explanation:
These are the correct requirements to ensure that WMM (Wi-Fi Multimedia) is working effectively. WMM is a standard that provides quality of service (QoS) for wireless networks by prioritizing traffic into four categories: voice, video, best effort, and background. To use WMM, both the APs and the controller must be Wi-Fi CERTIFIED for WMM, which means they have passed interoperability tests and comply with the standard. WMM must also be enabled on the APs and the controller, which is usually the default setting. The client device must also be Wi-Fi CERTIFIED for WMM and configured for WMM marking, which means it can tag its traffic with the appropriate priority level based on the application type. The other options are incorrect because they are either not related to WMM or not required for WMM to work.

Your customer is having issues with Wi-Fi 6 clients staying connected to poor-performing APs when a higher throughput APs are closer.
Which technology should you implement?
- A . Clearpass
- B . ClientMatch
- C . Airmatch
- D . ARM
B
Explanation:
Wi-Fi 6 is an industry certification for products that support the new wireless standard 802.11ax, also
known as "high-efficiency wireless". Wi-Fi 6 offers increased capacities, improved resource utilization
and higher throughput speeds than previous standards.
Option B: ClientMatch
This is because option B shows how to use ClientMatch to optimize the wireless performance of Wi-Fi 6 clients on a UniFi network. ClientMatch is a feature that uses machine learning to analyze the traffic patterns of each client and assign them to the best available AP based on their location, device type, and network conditions2.
Therefore, option B is the best technology to implement for your customer’s issue.

The administrator notices that wired guest users that have exceeded their bandwidth limit are not being disconnected Access Tracker in ClearPass indicates a disconnect CoA message is being sent to the AOS-CX switch.
An administrator has performed the following configuration
What is the most likely cause of this issue?
- A . Change of Authorization has not been globally enabled on the switch
- B . The SSL certificate for CPPM has not been added as a trust point on the switch
- C . There is a mismatch between the RADIUS secret on the switch and CPPM.
- D . There is a time difference between the switch and the ClearPass Policy Manager
What steps are part of the Key Management workflow when a wireless device is roaming
from AP1 to AP2? (Select two.)
- A . AP1 will cache the client’s information and send it to the Key Management service
- B . The Key Management service receives from AirMatch a list of all AP2’s neighbors
- C . The Key Management service receives a list of all AP1 s neighbors from AirMatch.
- D . The Key Management service then generates R1 keys for AP2’s neighbors.
- E . A client associates and authenticates with the AP2 after roaming from AP1
