Which two combinations are supported when configuring a Virtual Chassis Fabric? (Choose two.)
Which two statements are correct about VXLANs? (Choose two.)
Explanation:
VXLAN (Virtual Extensible LAN) is an overlay technology designed to support large-scale, multi-tenant environments. Unlike traditional VLANs which are limited to 4096 unique network identifiers, VXLANs can support up to 16 million unique network segments, providing significantly greater scalability. This is achieved through a 24-bit VXLAN Network Identifier (VNI). Additionally, being an overlay technology, VXLAN allows for the creation of virtualized Layer 2 networks over an existing Layer 3 infrastructure.

You are asked to configure VXLAN for you c data center using multicast to exchange VTEP information?
In this scenario, which two configuration parameters must match on the VTEPs in the same VXLAN segment? (Choose two.)
Explanation:
C) Multicast group must match on the VTEPs in the same VXLAN segment to ensure that they can properly participate in the same broadcast domain. D. VNI (VXLAN Network Identifier) must also match to ensure that all VTEPs are part of the same VXLAN overlay network.
Refer to the exhibit.
Referring to the exhibit, which two statements are correct? (Choose two.)
Which two statements about a DHCP relay in an EVPN-VXLAN fabric are correct? (Choose two.)
You are creating a new EVPN and are asked to selectively accept certain MAC advertisement routers from your EVPN peers using VXLAN Encapsulation.
Which statements is correct in this scenario?
Which two statements define the use of route targets and route distinguishers in an EVPN? (Choose two.)
Explanation:
A) Route distinguishers (RDs) ensure that routes from different clients remain unique within the data center domain by appending a unique identifier to each route, allowing overlapping IP spaces to coexist in the same network.
C) Route targets (RTs) identify the VRF into which the route should be placed. They are used in the import and export policies to control the distribution of routes among different VRFs, ensuring that routes are only shared with the intended VRFs.
Which two statements are true Virtual Chassis? (Choose two.)
You want to enable an EBGP-based IP fabric to allow ECMP routes to be populated into the RIB. In this scenario, which action will accomplish this task?
Explanation:
To enable ECMP (Equal-Cost Multi-Path) routes in the Routing Information Base (RIB) in an EBGP-based IP fabric, you should enable the 'multipath multiple-as' BGP parameter. This setting allows the use of multiple paths for BGP routes even when they come from different autonomous systems, which is key in a typical EBGP deployment in a data center IP fabric.
