Which transparent LAN service allows a service provider to offer Layer 2 Ethernet service to
connect an enterprise in a metro region?

A network engineer wants customers to retain routing information and Layer 2 connectivity for
non-Ethernet VPNs within their networks. Which two technologies can be used to accomplish this
goal? (Choose two.)

Two customer sites are connected to a service provider backbone through L2VPN. GRE is
carrying L2VPN circuits across the backbone. Which part of the packet carries the information to
route the L2VPN circuits?

Refer to the exhibit.

RTP header compression is used on the link for the voice packet. If the header overhead starts
reducing at 70%, and is reduced to the maximum amount, what will the overhead percentage be?

Which protocol is used to establish LSP tunnels, enabling resource allocation such as bandwidth
along the path?

A customer wants the minimum delay for the transit traffic that traverses the service provider core.
An engineer realizes that the customer sites are remotely dispersed and wants to give them a
specific path through the MPLS core with guaranteed bandwidth and without relying on the
shortest path of OSPF as the customer IGP. Which technology will achieve the required result?

A network engineer is implementing an MPLS network among devices from different vendors. The
devices must be configured with MPLS VPN service and MPLS TE. Based on options provided,
which three protocols fulfill all of these requirements? (Choose three.)

Refer to the exhibit.

An MPLS-based service provider wants to deploy QoS over its backbone. Original customer QoS
information must be preserved when the packet leaves the MPLS network. In addition, the egress
LSR must forward packets according to the LSP Diff-Service information, as depicted in the
topology. Which QoS model satisfies these requirements?

A network engineer wants to leak only IPv6 loopback addresses from level 2 to level 1. All of the
other level 2 prefixes should not be advertised into level 1. Which technique will achieve this goal,
based on IOS SRE release?

DRAG DROP
Drag the layer 2 QoS marking type on the left to the correct layer 2 QoS names on the right.
