What is a characteristic of VXLAN?
VXLAN is a network virtualization technology often used in multi-tenant environments. It allows for the segmentation and isolation of networks in virtualized and cloud environments, making it a suitable solution for multi-tenant scenarios. This characteristic aligns with the description provided in option D.
It can't be A as it uses a L3 underlay, not a L2 underlay.
VXLAN offers the following benefits: VLAN flexibility in multitenant segments - D Higher scalability Improved network utilization https://www.ciscopress.com/articles/article.asp?p=2999385&seqNum=3
A is incorrect bcoz VXLAN extends Layer 2 and Layer 3 overlay networks over a Layer 3 underlay, not a Layer 2 underlay. VXLAN encapsulates Layer 2 frames within UDP packets, allowing them to be transmitted over a Layer 3 network.
'D' 'A' makes no sense. L2 underlay?
D is correct
i will go with D cause A have a tiny issue
D is the correct answer. D is wrong: 'A VXLAN is a virtual layer 2 network (known as the overlay network) built on top of an existing physical layer 3 network (known as the underlay network). VXLAN uses a logical tunnel to transport traffic between two endpoints.'
Whoops! D is the correct answer. A is wrong: 'A VXLAN is a virtual layer 2 network (known as the overlay network) built on top of an existing physical layer 3 network (known as the underlay network). VXLAN uses a logical tunnel to transport traffic between two endpoints.' 'Built on top of an existing physical layer 3 network' is the key concept.'
A. **It extends Layer 2 and Layer 3 overlay networks over a Layer 3 underlay.** VXLAN is a network virtualization technology that enables the creation of Layer 2 and Layer 3 overlay networks on top of a Layer 3 (IP) underlay network. VXLAN is often used in virtualized and cloud environments to provide network segmentation and isolation. It allows for the extension of Layer 2 domains across Layer 3 networks. The other options are not accurate: B. VXLAN typically has a 50-byte packet header. C. VXLAN uses UDP (User Datagram Protocol) for transport, not TCP. D. VXLAN is often used in multi-tenant environments, but the term "multi-tenant solution" is a bit broad. VXLAN itself is a technology that facilitates network virtualization and segmentation, which can be used in multi-tenant scenarios.
You've mistyped the presented answer, which is: "A. It extends Layer 2 and Layer 3 overlay networks over a **Layer 2** underlay" The underlay, as you pointed out, should be Layer 3, so A is incorrect. Leaving D as the correct answer.
Shouldnt be A?
It extends L2 over L3.
