Which two statements are correct about VXLANs? (Choose two.)

VXLANs have smaller broadcast domains than VLANs.
VXLANs have smaller broadcast domains than VLANs.
VXLANs have a smaller logical network identifier than VLANs.
VXLANs have a smaller logical network identifier than VLANs.
VXLANs can have a theoretical maximum of 16 million unique networks.
VXLANs can have a theoretical maximum of 16 million unique networks.
VXLANs are an overlay technology.
VXLANs are an overlay technology.
Suggested answer: C, D
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.

Question 4

Report Export Collapse

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.)

VLAN ID
VLAN ID
Routing instance name
Routing instance name
Multicast group
Multicast group
VNI
VNI
Suggested answer: C, D
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.

Question 8

Report Export Collapse

Which two statements define the use of route targets and route distinguishers in an EVPN? (Choose two.)

Route distinguishers ensure that routes from different client remain unique within the data center domain
Route distinguishers ensure that routes from different client remain unique within the data center domain
Route targets ensure that routes from different clients remain unique within the data center domain
Route targets ensure that routes from different clients remain unique within the data center domain
Route distinguishers identify the VRF into which the route should be placed
Route distinguishers identify the VRF into which the route should be placed
Route targets identify the VRF into which the route should be placed
Route targets identify the VRF into which the route should be placed
Suggested answer: A, C
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.

Question 10

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?

Enable the forwarding-options ecmp-do-local-lookup parameter.
Enable the forwarding-options ecmp-do-local-lookup parameter.
Enable the multipath multiple-as BGP parameter.
Enable the multipath multiple-as BGP parameter.
Enable the routing-options multipath global parameter.
Enable the routing-options multipath global parameter.
Enable the chassis ecmp-alb parameter.
Enable the chassis ecmp-alb parameter.
Suggested answer: B
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.
