HP HPE6-A85 Dumps Questions Answers

The correct statement when comparing 5 GHz and 6 GHz channels with identical channel widths is that 5 GHz channels travel different distances and provide different throughputs to clients compared to 6 GHz channels. This statement reflects the fact that higher frequency signals tend to have higher attenuation Attenuation is a general term that refers to any reduction in signal strength during transmission over distance or through an object or medium . Higher attenuation means that higher frequency signals have shorter range and lower throughput than lower frequency signals. Some facts about this statement are:

• 5 GHz channels have lower frequency than 6 GHz channels, which means they have lower attenuation than 6 GHz channels.
• Lower attenuation means that 5 GHz channels can travel longer distances and provide higher throughputs to clients than 6 GHz channels with identical channel widths.
• However, the difference in distance and throughput between 5 GHz and 6 GHz channels may not be significant in indoor environments where there are many obstacles and reflections that affect signal propagation.
• The advantage of using 6 GHz channels over 5 GHz channels is that they offer more spectrum availability, less interference, and more non-overlapping channels than 5 GHz channels.

The other options are not correct because:

• 5 GHz channels travel the same distances and provide different throughputs to clients compared to 6 GHz channels: This option is false because 5 GHz channels do not travel the same distances as 6 GHz channels due to higher attenuation of higher frequency signals.
• 5 GHz channels travel the same distances and provide the same throughputs to clients compared to 6 GHz channels: This option is false because 5 GHz channels do not travel the same distances or provide the same throughputs as 6 GHz channels due to higher attenuation of higher frequency signals.
• 5 GHz channels travel different distances and provide the same throughputs to clients compared to 6 GHz channels: This option is false because 5 GHz channels do not provide the same throughputs as

6 GHz channels due to higher attenuation of higher frequency signals.

The Alerts and Events dashboard displays all types of alerts and events generated for events pertaining to device provisioning, configuration, and user management. You can use the Config icon to configure alerts and notifications for different alert categories and severities1. You can also view the alerts and events in the List view and Summary view2.

The status of “ALFOE” means that LACP Link Aggregation Control Protocol (LACP) is a network protocol that provides dynamic negotiation of link aggregation between two devices. LACP allows multiple physical links to be combined into a single logical link for increased bandwidth, redundancy, and load balancing. LACP is defined in IEEE 802.3ad standard. is working fine with no problems when checking LACP with “show lacp interfaces”. The status of “ALFOE” is an acronym that stands for:

• A: Active - The interface is actively sending LACP packets to negotiate link aggregation with the peer device.
• L: Link Up - The interface has physical connectivity with the peer device.
• F: Aggregatable - The interface can be aggregated with other interfaces into a single logical link.
• O: Synchronized - The interface has successfully negotiated link aggregation parameters with the peer device and can transmit or receive traffic on the logical link.
• E: Collecting/Distributing - The interface is collecting incoming traffic from the peer device and distributing outgoing traffic to the peer device on the logical link.

The other options are not correct because:

• The interface on the local switch is configured as static-LAG: This option is false because static-LAG does not use LACP to negotiate link aggregation. Static-LAG requires manual configuration of link aggregation parameters on both devices and does not have any status indicators.
• LACP is not configured on the peer side: This option is false because if LACP is not configured on the peer side, the status of the interface would be “ALF–” instead of “ALFOE”. This means that the interface would not be synchronized or collecting/distributing with the peer device.
• LACP is in a synchronizing process: This option is false because if LACP is in a synchronizing process, the status of the interface would be “ALF-O” instead of “ALFOE”. This means that the interface would not be collecting/distributing with the peer device.
