ENSA Module 7 -- MPLS

Front

What does MPLS stand for in networking?

Back

Multi-Protocol Label Switching

Front

In MPLS, what is the primary function of a PE?

Back

To assign labels to incoming packets

Front

What is the main advantage of MPLS over traditional IP routing? Options: Lower cost, Faster packet forwarding, Easier configuration, Better security

Back

Faster packet forwarding

Front

How does MPLS improve the efficiency of data transmission in a network?

Back

By using labels instead of IP addresses for routing

Front

What is a key feature of MPLS VPNs?

Back

They provide a virtual private network over an MPLS infrastructure

Front

Which layer of the OSI model does MPLS operate on? Options: Layer 2, Layer 3, Layer 2.5, Layer 3.5

Back

Layer 2.5

Front

What is a common use case for MPLS in modern networks? Options: Home networking, Small office networks, Large enterprise and service provider networks, Personal mobile devices

Back

Large enterprise and service provider networks

Front

The service provider participates in customer routing by establishing a peering between the customer’s routers and the provider’s routers.

Back

L3 MPLS VPN

Front

The customer routes that are received by the provider’s router are redistributed through the MPLS network to the customer’s remote locations.

Back

L3 MPLS VPN

Front

The service provider is not involved in the customer routing. Instead, the provider deploys a Virtual Private LAN Service (VPLS) to emulate an Ethernet multiaccess LAN.
