These are the correct statements about access from the servers to the Core when the ISL link between the switches fails, but the keepalive interface functions. Server 1 can access the core layer via both uplinks because it is connected to VSX-A, which is still active for VLAN 10. Server 2 can also access the core layer via its uplink to VSX-B, which is still active for VLAN 10 because of Active Gateway feature. Server 1 and Server 2 can communicate with each other via the core layer because they are in the same VLAN and subnet, and their traffic can be routed through the core switches. The other statements are incorrect because they either describe scenarios that are not possible or not relevant to the question.

Function

Correct Role

Is the Authentication Source

Backend Services

Is responsible for granting or denying access

Authentication Server

Software that enables use of 802.1X network authentication protocol

Supplicant

The device that controls initial network access

Authenticator

IEEE 802.1X separates network-access authentication into distinct functional roles. The supplicant is the client-side software participating in 802.1X authentication. It runs on the endpoint and exchanges EAPOL messages with the network authenticator when requesting access.

The authenticator is the network-access device controlling the port or wireless connection. In an Aruba deployment, this can be an Aruba switch, AP, or gateway/controller. It operates as the gatekeeper and controls the client ' s initial access while relaying authentication information between the supplicant and authentication server. Aruba explicitly describes the authenticator as the component that permits or denies network access at the enforcement point. Aruba Networking

The Authentication Server, typically HPE Aruba Networking ClearPass Policy Manager, processes authentication requests and ultimately returns an accept or reject decision to the authenticator. Aruba Networking

Finally, Backend Services supply the authentication source. Examples include Microsoft Active Directory, LDAP, SQL databases, or other identity repositories. Aruba defines an authentication source as the identity store against which users or devices are authenticated. Aruba Networking

These are two benefits enabled by LLDP-MED (Link Layer Discovery Protocol - Media Endpoint Discovery). LLDP-MED is an extension of LLDP that provides additional capabilities for network devices such as VoIP phones and APs. One of the capabilities is to automatically configure voice VLANs for VoIP phones, which allows them to be placed in a separate VLAN from data devices and receive QoS and security policies. Another capability is to request power as needed from PoE-enabled switch ports, which allows APs to adjust their power consumption and performance based on the available power budget. The other options are incorrect because they are either not enabled by LLDP-MED or not related to LLDP-ME

D.  

a) A device with IP address 10.1.3.7 in a network wants to send the traffic stream to a device with IP address 10.13.4.2 in the other network - >  Unicast 

b) One/more senders and one/more recipients participate in data transfer traffic - >  Multicast 

c) Sent to all hosts on a remote network - >  IP Directed Broadcast 

d) Sent to all NICs on the same network segment as the source NIC - >  Broadcast
