HPE6-A85 Exam Dumps - HP Certification Questions and Answers

The client's broadcast domain in ArubaOS can be set with role-based VLAN overrides within the firewall role settings. This allows for dynamic assignment of VLANs to users based on their role, which determines their level of network access, including their broadcast domain.

When using an Aruba standalone AP, selecting “Native VLAN” for the Client VLAN Assignment means that the clients will get their IP addresses from the same subnet as the access point’s IP address. This is because the access point acts as a DHCP server for the clients in this mode.References:https://www.arubanetworks.com/techdocs/Instant_86_WebHelp/Content/instant-ug/iap-dhcp/iap-dhcp.htm

OSPF Open Shortest Path First. OSPF is a link-state routing protocol that uses a hierarchical structure to create a routing topology for IP networks. OSPF routers exchange routing information with their neighbors using Hello packets, which are sent periodically on each interface. To establish an adjacency Adjacency is a relationship formed between selected neighboring routers for the purpose of exchanging routing information., OSPF routers must agree on several parameters, including Hello timers, which specify how often Hello packets are sent on an interface. If the Hello timers do not match between neighboring routers, they will not form an adjacency and will not exchange routes.

AAA Authentication, Authorization, and Accounting (AAA) Authentication, Authorization, and Accounting (AAA) is a framework that provides security services for network access control . AAA consists of three components:

Authentication: The process of verifying the identity of a user or device that wants to access the network based on credentials such as username and password , certificates , tokens , etc . Authentication can use different protocols such as PAP , CHAP , EAP , RADIUS , TACACS+ , etc .

Authorization: The process of granting or denying access to network resources based on the identity and privileges of a user or device . Authorization can use different methods such as ACLs , RBAC , MAC , DAC , etc .

Accounting: The process of recording and reporting the activities and usage of network resources by users or devices . Accounting can use different formats such as syslog , SNMP , NetFlow , etc .

service. Here is my answer:

The correct match for each AAA service with its definition is:

Accounting: C. Tracking user activity on the network

Authentication: D. Who can access the network based on credentials/certificates

Authorization: B. Control users access on the network

The other options are not correct matches because:

A list of rules that specifies which entities are permitted or denied access: This option is a definition of an access control list (ACL) Access Control List (ACL) Access Control List (ACL) is a list of rules that specifies which entities are permitted or denied access to a network resource such as a router , switch , firewall , server , etc . ACLs can be based on different criteria such as source and destination IP addresses , port numbers , protocol types , time of day , etc . ACLs can be applied to different interfaces or directions such as inbound or outbound .ACLs can be verified by using commands such as show access-lists , show ip access-lists , debug ip packet , etc . , not an AAA service.

Who can access the network based on credentials/certificates: This option is a definition of authentication, not authorization. Authorization is the process of granting or denying access to network resources based on the identity and privileges of a user or device, not based on credentials/certificates.

Aruba ClientMatch is a technology that continuously monitors client behavior and automatically adjusts client connections to optimize Wi-Fi performance. This includes steering clients to the least congested access point and the best radio on the WLAN, which effectively provides load balancing across different radio bands and AP radios.

Features: 1) Clustered Instant Access Points Aruba OS version: a) Aruba OS 8

Features: 2) Dynamic Radius Proxy Aruba OS version: a) Aruba OS 8

Features: 3) Scales to more than 10,000 devices Aruba OS version: b) Aruba OS 10

Features: 4) Unifies wired and wireless management Aruba OS version: a) Aruba OS 8 

Features: 5) Wireless controllers Aruba OS version: a) Aruba OS 8

ArubaOS is the operating system for all Aruba Mobility Controllers (MCs) and controller-managed wireless access points (APs). ArubaOS 8 delivers unified wired and wireless access, seamless roaming, enterprise grade security, and a highly available network with the required reliability to support high density environments1. Some of the features of ArubaOS 8 are:

Clustered Instant Access Points: This feature allows multiple Instant APs to form a cluster and share configuration and state information. This enables seamless roaming, load balancing, and fast failover for clients2.

Dynamic Radius Proxy: This feature allows an MC to act as a proxy for RADIUS authentication requests from clients or APs. This simplifies the configuration and management of RADIUS servers and reduces the network traffic between MCs and RADIUS servers3.

Wireless controllers: Aruba wireless controllers are devices that centrally manage and control the wireless network. They provide functions such as AP provisioning, configuration, security, policy enforcement, and network optimization.

ArubaOS 10 is the next-generation operating system that works with Aruba Central, a cloud-based network management platform. ArubaOS 10 delivers greater scalability, security, and AI-powered optimization across large campuses, branches, and remote work environments. Some of the features of ArubaOS 10 are:

Scales to more than 10,000 devices: ArubaOS 10 can support up to 10,000 devices per cluster, which is ten times more than ArubaOS 8. This enables customers to scale their networks without compromising performance or reliability.

Unifies wired and wireless management: ArubaOS 10 provides a single platform for managing both wired and wireless devices across the network. Customers can use Aruba Central to configure, monitor, troubleshoot, and update their devices from anywhere.

Both ArubaOS 8 and ArubaOS 10 share some common features, such as:

Unifies wired and wireless management: Both operating systems provide unified wired and wireless access for customers who use Aruba switches and APs. Customers can use a single interface to manage their entire network infrastructure1 .

Based on the exhibit showing the logging server configurations, server 172.17.17.43 will receive the smallest quantity of data because it is set to the "Warning" event log level. This means it will only log events that are categorized as warnings or higher severity, which are typically less frequent than lower severity levels such as "Information," "Debug," or "Emergency."

For "headless" devices that lack 802.1X support, Multi-Preshared Keys (mPSK) provide a more secure alternative to WPA2-Personal, which uses a single preshared key. mPSK allows for the assignment of unique PSKs to devices or groups of devices, which enhances security by not sharing a single PSK across multiple devices.

To troubleshoot an Aruba CX 6200 switch that is failing to boot correctly, accessing the switch via the RJ-45 console port on any of its member switches provides direct access to the switch's console for troubleshooting. This method allows a network technician to interact with the boot process, view boot messages, and access boot options, including the selection of different OS images or ServiceOS for recovery purposes.

AirMatch is a feature that provides centralized RF planning and optimization service for Aruba wireless networks. It uses cloud-based algorithms and machine learning to optimize the RF performance and user experience.References:https://www.arubanetworks.com/assets/ds/DS_AirMatch.pdf

In Aruba networks, the recommended Virtual Switching Framework (VSF) topologies include the daisy chain plus Multi-Active Detection (MAD) and the ring topology. The daisy chain topology with MAD provides a straightforward and effective way to connect multiple switches in a series while ensuring there is a mechanism in place (MAD) to detect and handle situations where more than one switch in the VSF might become active simultaneously. The ring topology offers redundancy by creating a looped connection pattern among the VSF members, enhancing network resilience and reliability.
