Virtual Extensible LAN

What is the primary purpose of Data Center Interconnect (DCI)?

• To treat each data center as an individual entity.

• To connect multiple data centers together seamlessly across geographic distances.

• To limit the distribution of applications to a single data center.

• To prevent applications from moving between different cloud-based data centers.

What is a significant challenge when scaling applications across multiple data centers?

• Ensuring all data centers use the same physical connectivity type.

• Managing different IP addressing schemes across data centers.

• Limiting the number of virtual machines per data center.

• Preventing applications from being distributed globally.

How does Virtual Extensible LAN (VXLAN) differ from traditional VLANs in terms of scale and functionality?

• VLANs support more virtual networks than VXLAN.

• VXLAN is limited to Layer 2 domains, while VLANs operate at Layer 3.

• VXLAN supports a significantly larger number of virtual networks and can tunnel frames across Layer 3 networks.

• VLANs are designed for large service providers, unlike VXLAN.

What is a VXLAN Tunnel Endpoint (VTEP)?

• A virtual machine running within a data center.

• A physical server that hosts multiple virtual machines.

• A top of rack switch that contains a VXLAN tunnel endpoint with an IP address.

• A virtual switch that connects virtual machines to the network.

What is the correct order of headers added to an original frame during VXLAN encapsulation?

• IP Header, UDP Header, VXLAN Header, Ethernet Header

• Ethernet Header, IP Header, UDP Header, VXLAN Header

• VXLAN Header, UDP Header, IP Header, Ethernet Header

• UDP Header, VXLAN Header, Ethernet Header, IP Header
