WAN Architectures Study Set | Jeremy's IT Lab Day 53

[...] creates tunnels like IPsec, but does not encrypt the original packet.

GRE

[...] is a Cisco-developed solution that allows routers to dynamically create a full mesh of IPsec tunnels without having to manually configure every single tunnel.

DMVPN

[...] provides Internet connectivity via phone lines.

DSL

[...] provides Internet connectivity via TV lines.

Cable (CATV) Internet

[...] VPNs are used to permanently connect two sites over the Internet.

Site-to-site

[...] VPNs are used to provide on-demand access to the company network for end devices.

Remote-access

[...] VPNs typically use IPsec.

Site-to-site

[...] VPNs typically use TLS.

Remote-access

A cable [...] is required to convert data into a format suitable to be sent over the TV lines.

modem

A DSL [...] is required to convert data into a format suitable to be sent over the phone lines.

Does GRE support broadcast and multicast traffic?

Yes

Does IPsec support broadcast and multicast traffic?

No

In [...] MPLS VPNs, CE routers and PE routers can form routing protocol peerings.

Layer 3

In [...] MPLS VPNs, CE routers form routing protocol peerings with each other.

Layer 2

In [...] MPLS VPNs, the entire service provider network is transparent to the customer.
