The calculated Equivalent Isotropic Radiated Power (EIRP) for AP1 is 17 dBm.

EIRP is the measured radiated power of an antenna in a specific direction. It is equal to the input power to the antenna multiplied by the gain of the antenna. It can also take into account the losses in transmission line, connectors, and other components. The formula for EIRP is:

EIRP = P + G - L

where P is the output power of the radio, G is the gain of the antenna, and L is the loss of the cable and connectors.

For AP1, we have:

P = 10 dBm G = 9 dBi L = 2 dB

Therefore,

EIRP = 10 + 9 - 2 EIRP = 17 dBm

In MSTP, root-bridge priority is configured per MST instance , not directly per individual VLAN. Since Core-1 already has spanning-tree instance 1 priority 0, Core-1 is intended to become the preferred root for MST instance 1 . To make VLAN 10 use that spanning-tree topology, VLAN 10 must therefore be mapped into instance 1 with:

spanning-tree instance 1 vlan 10

HPE Aruba Networking documents this exact syntax and states that the command either creates an MST instance with the specified VLAN mapping or maps a VLAN to an existing instance. Aruba Networks

This is how MSTP provides VLAN load balancing. Different VLANs can be assigned to separate MST instances, and each instance can have a different root bridge. For example, VLAN 10 can belong to instance 1 with Core-1 as root, while VLAN 20 can belong to another instance whose root priority favors Core-2 . Aruba specifically describes this ability to forward different VLAN groups along separate paths as an MSTP load-sharing mechanism. Aruba Networks

Options B, C, and D are not the appropriate AOS-CX MSTP VLAN-to-instance mapping syntax. The required command is therefore A .

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.
