NEW QUESTION # 33
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. operators
- B. auditors
- C. sysops
- D. administrators
Answer: B
Explanation:
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.

NEW QUESTION # 34
You need to ensure that voice traffic sent through an ArubaOS-CX switch arrives with minimal latency What is the best scheduling technology to use for this task?
- A. DWRR queuing
- B. Rate limiting
- C. QoS shaping
- D. Strict queuing
Answer: D
Explanation:
Explanation
Strict queuing is the best scheduling technology to use for voice traffic on an AOS-CX switch. Scheduling is a mechanism that determines how packets are transmitted from different queues on an egress port. Strict queuing is a scheduling method that gives the highest priority queue absolute preference over all other queues, regardless of their size or utilization. Voice traffic should be assigned to the highest priority queue and scheduled with strict queuing to ensure minimal latency and jitter. The other options are incorrect because they are either not scheduling methods or not optimal for voice traffic. References:

NEW QUESTION # 35
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. Open Network Access
- D. Wired Equivalent Privacy
Answer: B
Explanation:
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. References: https://www.arubanetworks.com/assets/tg/TG_OWE.pdf
NEW QUESTION # 36
Your Aruba CX 6300 VSF stack has OSPF adjacency over SVI 10 with LAG 1 to a neighboring device The following configuration was created on the switch:
- A.
- B.
- C.
- D.
Answer: C
Explanation:
Explanation
The correct configuration for OSPF adjacency over SVI 10 with LAG 1 to a neighboring device is shown in Option C. The configuration includes the following steps:
* Create a VLAN 10 and assign it a name and an IP address.
* Create a LAG 1 and assign it a name and a mode of dynamic or static.
* Add member ports to LAG 1 and enable the LAG interface.
* Assign VLAN 10 as the untagged VLAN for LAG 1.
* Enable OSPF on the switch and assign it a router ID.
* Create an OSPF area 0 and add SVI 10 as an interface in that area.
Option A is incorrect because it does not enable OSPF on the switch or create an OSPF area. Option B is incorrect because it assigns VLAN 10 as the tagged VLAN for LAG 1, which is not compatible with SVI 10.
Option D is incorrect because it does not add member ports to LAG 1 or enable the LAG interface.

NEW 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. Attach OSPF process ID in the VRF configuration.
- B. Create a new OSPF process ID with vrf name.
- C. Create a new OSPF area, and attach VRF name.
- D. Attach a new OSFP process ID with a custom routing table
Answer: B
Explanation:
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. References:

NEW QUESTION # 38
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. There is a time difference between the switch and the ClearPass Policy Manager
- B. The SSL certificate for CPPM has not been added as a trust point on the switch
- C. Change of Authorization has not been globally enabled on the switch
- D. There is a mismatch between the RADIUS secret on the switch and CPPM.
Answer: C
Explanation:
Explanation
Change of Authorization (CoA) is a feature that allows ClearPass Policy Manager (CPPM) to send messages to network devices such as switches to change the authorization state of a user session. CoA requires that both CPPM and the network device support this feature and have it enabled. For AOS-CX switches, CoA must be globally enabled using the command radius-server coa enable. If CoA is not enabled on the switch, the disconnect CoA message from CPPM will be ignored and the user session will not be terminated. References:

NEW QUESTION # 39
A large retail client is looking to generate a rich set of contextual data based on the location information of wireless clients in their stores Which standard uses Round Trip Time (RTT) and Fine Time Measurements (FTM) to calculate the distance a client is from an AP?
- A. 802.11mc
- B. 802.11be
- C. 802.11ah
- D. 802.11V
Answer: A
Explanation:
Explanation
802.11mc is a standard that uses Round Trip Time (RTT) and Fine Time Measurements (FTM) to calculate the distance a client is from an AP. 802.11mc defines a protocol for exchanging FTM frames between an AP and a client, which contain timestamps that indicate when the frames were transmitted and received. By measuring the RTT of these frames, the AP or the client can estimate their distance based on the speed of light. The other options are incorrect because they either do not use RTT or FTM or do not exist as standards. References:

NEW QUESTION # 40
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. The encapsulation protocol used is VXLAN.
- B. On the source AOS-CX switch, the destination specified is the switch to which the administrator's desktop is connected
- C. The encapsulation protocol is UDP.
- D. On the source AOS-CX switch, the destination specified is the administrators desktop
- E. The encapsulation protocol used is GRE.
Answer: D,E
Explanation:
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.

NEW QUESTION # 41
In AOS 10. which session-based ACL below will only allow ping from any wired station to wireless clients but will not allow ping from wireless clients to wired stations"? The wired host ingress traffic arrives on a trusted port.
- A. ip access-list session pingFromWired any any svc-icmp deny any user svc-icmp permit
- B. ip access-list session pingFromWired any user any permit
- C. ip access-list session pingFromWired any any svc-icmp permit user any svc-icmp deny
- D. ip access-list session pingFromWired user any svc-icmp deny any any svc-icmp permit
Answer: A
Explanation:
Explanation
A session-based ACL is applied to traffic entering or leaving a port or VLAN based on the direction of the session initiation. To allow ping from any wired station to wireless clients but not vice versa, a session-based ACL should be used to deny icmp echo traffic from any source to any destination, and then permit icmp echo-reply traffic from any source to user destination. The user role represents wireless clients in AOS 10.

NEW QUESTION # 42
A customer wants to provide wired security as close to the source as possible The wired security must meet the following requirements:
-allow ping from the IT management VLAN to the user VLAN
-deny ping sourcing from the user VLAN to the IT management VLAN
The customer is using Aruba CX 6300s
What is the correct way to implement these requirements?
- A. Apply an outbound ACL on the user VLAN allowing temp echo-reply traffic toward the IT management VLAN
- B. Apply an inbound ACL on the user VLAN allowing icmp echo-reply traffic toward the IT management VLAN
- C. Apply an inbound ACL on the user VLAN denying icmp echo traffic toward the IT management VLAN
- D. Apply an outbound ACL on the user VLAN denying icmp echo traffic toward the IT management VLAN
Answer: C
Explanation:
Explanation
An inbound ACL is applied to traffic entering a port or VLAN. An outbound ACL is applied to traffic leaving a port or VLAN4. To deny ping sourcing from the user VLAN to the IT management VLAN, an inbound ACL on the user VLAN should be used to filter icmp echo traffic toward the IT management VLAN. Icmp echo-reply traffic is not needed to be allowed because it is already permitted by default5. References: 4

NEW QUESTION # 43
What is one advantage of using OCSP vs CRLs for certificate validation?
- A. higher availability for certificate validation
- B. supports longer certificate validity periods
- C. less complex to implement
- D. reduces latency between the time a certificate is revoked and validation reflects this status
Answer: D
Explanation:
Explanation
OCSP is a protocol that allows clients to query the CA or a trusted responder for the status of a specific certificate. OCSP requests and responses are smaller and faster than CRLs, and they can provide real-time information about the revocation status of a certificate12. CRLs are lists of all revoked certificates that are downloaded from the CA. CRLs can present issues, as they can become outdated and have to be downloaded frequently13. Therefore, OCSP reduces latency between the time a certificate is revoked and validation reflects this status. References: 1 https://sectigostore.com/blog/ocsp-vs-crl-whats-the-difference/ 2

NEW QUESTION # 44
What steps are part of the Key Management workflow when a wireless device is roaming from AP1 to AP2?
(Select two.)
- A. The Key Management service receives from AirMatch a list of all AP2's neighbors
- B. A client associates and authenticates with the AP2 after roaming from AP1
- C. The Key Management service then generates R1 keys for AP2's neighbors.
- D. The Key Management service receives a list of all AP1 s neighbors from AirMatch.
- E. AP1 will cache the client's information and send it to the Key Management service
Answer: C,D
Explanation:
Explanation
Key Management is a service that runs on Aruba Mobility Controllers (MCs) or Mobility Master (MM) to optimize roaming performance for wireless clients. Key Management works with AirMatch, a service that optimizes radio resource management for Aruba APs, to pre-generate and distribute R1 keys for neighboring APs before a client roams. When a wireless device is roaming from AP1 to AP2, the following steps are part of the Key Management workflow3:
* The client associates and authenticates with AP1 using 802.1X or PSK methods.
* The Key Management service caches the client's information and generates an R0 key for the client.
* The Key Management service receives a list of all AP1's neighbors from AirMatch.
* The Key Management service then generates R1 keys for AP1's neighbors using the R0 key and sends them to the corresponding APs.
* When the client roams to AP2, one of AP1's neighbors, it performs an 802.11r fast transition using the pre-generated R1 key without needing to re-authenticate.

NEW QUESTION # 45
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 Local with EAP-TLS
- B. MPSK and an internal RADIUS server
- C. MPSK Local with MAC Authentication
- D. ClearPass Policy Manager
- E. Local User Derivation Rules
Answer: B,D
Explanation:
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. References: 1

NEW QUESTION # 46
Your customer is interested in hearing more about how roles can help keep consistent policy enforcement in a distributed overlay fabric How would you explain this concept to them''
- A. Group Based Policy ID is applied on ingress VTEP after device authentication and policy is enforced on egress VTEP
- B. Role-based policies enhance User Based Tunneling across the campus network and the policy traffic is protected with iPsec
- C. Role-based policies are tied to IP addresses which have an advantage over IP-based policies and role names are sent between VTEPs
- D. Group Based Policy ID is applied on egress VTEP after device authentication and policy is enforced on ingress VTEP
Answer: A
Explanation:
Explanation
This is the correct explanation of how roles can help keep consistent policy enforcement in a distributed overlay fabric. Roles are used to assign group based policy IDs (GBPs) to devices after they authenticate with ClearPass or a local database. GBPs are then used to tag the traffic from the devices and send them to the ingress VTEP, which applies the GBP on the VXLAN header. The egress VTEP then enforces the policy based on the GBP and the destination device. The other options are incorrect because they either do not describe the correct sequence of events or do not use the correct terms. References:

NEW QUESTION # 47
What are the requirements to ensure that WMM is working effectively'? (Select two)
- A. The Aruba AOS10 APs installed have to be converted to controlled mode
- B. All APs need to be from the AP-5xx series and AP-6xx series which are Wi-Fi CERTIFIED 6.
- C. The AP needs to be connected via a tagged VLAN to the wired port
- D. The Client must be Wi-Fi CERTIFIED for WMM and configured for WMM marking.
- E. The APs and the controller are Wi-Fi CERTIFIED for WMM which is enabled
Answer: D,E
Explanation:
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. References:

NEW QUESTION # 48
You need to create a keepalive network between two Aruba CX 8325 switches for VSX configuration How should you establish the keepalive connection?
- A. routed port in custom VRF
- B. SVI, VLAN trunk allowed all on ISL in default VRF
- C. loopback 0 and OSPF area 0 in default VRF
- D. SVI, VLAN trunk allowed all on ISL in custom VRF
Answer: A
Explanation:
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. References:

- A. show port-access role
- B. show port-access captiveportal profile
- C. show aaa authentication port-access interface all client-status
- D. diag-dump captiveportal client verbose
Answer: C
Explanation:
Explanation
The show aaa authentication port-access interface all client-status command displays the status of all clients authenticated by port-based access control on all interfaces. The output includes the MAC address, user role, VLAN ID, and session timeout for each client. This command can be used to examine information on which role the guest user has been assigned by the AOS-CX switch. References:

NEW QUESTION # 50
In an ArubaOS 10 architecture using an AP and a gateway, what happens when a client attempts to join the network and the WLAN is configured with OWE?
- A. RADIUS protocol is utilized.
- B. The Gateway will not respond.
- C. Authentication information is not exchanged
- D. No encryption is applied.
Answer: C
Explanation:
Explanation
This is the correct statement about what happens when a client attempts to join the network and the WLAN is configured with OWE (Opportunistic Wireless Encryption). OWE is a standard that provides encryption for open networks without requiring any authentication or credentials from the client or the network. OWE uses a Diffie-Hellman key exchange mechanism to establish a secure session between the client and the AP without exchanging any authentication information. The other options are incorrect because they either describe scenarios that require authentication or encryption methods that are not used by OWE. References:
