HP Aruba Certified Campus Access Associate HPE6-A85 Exam Practice Test

Answer : D

ICMP (Internet Control Message Protocol) is used by network devices to send error and operational information related to IP communications. It is used to send messages like 'destination unreachable' or 'time exceeded' when there are issues in IP communication

Answer : A

On Aruba switches, the Link Layer Discovery Protocol (LLDP) is enabled by default on all ports. This protocol is an industry-standard network discovery protocol that is used for network devices to advertise their identity, capabilities, and neighbors on a locally managed network, typical in an IEEE 802 network. This is beneficial for network mapping and troubleshooting purposes. Since LLDP is enabled by default, there is no need for any additional configuration on Switch 1 port 1/1/24 to receive LLDP messages from Router 1, as long as LLDP is not disabled on the port.

Answer : C

A slow amber-flashing Stack-LED indicates that stacking mode is selected on the switch. This means that the switch is ready to join a stack or form a new stack if no other switches are present.

Answer : B

Virtual Router Redundancy Protocol (VRRP) is a network protocol that provides automatic assignment of available Internet Protocol (IP) routers to participating hosts. VRRP sends its messages over multicast for communication among routers for the election process of the master and advertisement of the virtual IP address.

Answer : D

While both 5 GHz and 6 GHz channels can provide similar throughputs, the higher frequency of the 6 GHz band means its signals have a shorter range and are more attenuated by obstacles compared to 5 GHz signals. This results in 5 GHz channels generally being able to travel longer distances than 6 GHz channels under similar conditions, although both can support high data rates for connected clients.

Answer : B

In the context of Aruba networks, a Microbranch environment is managed using a group persona that aligns with the functionality required. ArubaOS 10 Branch Gateway Group Persona would be the correct device type and group persona for managing a Microbranch environment, as it would provide the necessary features and controls for branch networking requirements.

Answer : C

Aruba AirMatch is a feature that optimizes RF Radio Frequency. RF is any frequency within the electromagnetic spectrum associated with radio wave propagation. When an RF current is supplied to an antenna, an electromagnetic field is created that then is able to propagate through space. performance and user experience by using machine learning algorithms and historical data to dynamically adjust AP power levels, channel assignments, and channel width. AirMatch performs live firmware upgrades on Aruba APs by partitioning all the APs based on RF neighborhood data and minimizing the impact on clients. AirMatch uses a rolling upgrade process that upgrades one partition at a time while ensuring that adjacent partitions are not upgraded simultaneously.
