You are designing a multisite VPN solution for a customer and you are concerned with the
additional overhead of point-to-point tunnels and the associated overlay routing with DMVPN.
How does a GDOI-based VPN eliminate the additional tunnel and routing overhead found in
DMVPN?

You have been tasked to create a Layer 2 network design that uses vPC to provide resiliency
and avoid loops. vPC removes Layer 2 loops while providing redundancy through which
mechanism?

Refer to the exhibit.

You are designing an IPv4 unicast Layer 3 VPN load-balancing solution. Which L3VPN feature
needs to be configured on the PE routers to support the design requirement?

A metro service provider is planning Resilient Ethernet Protocol for his backbone. Which two
aspects must be considered before the network design is finalized? (Choose two.)

In an MPLS-VPN environment, what is the effect of configuring an identical set of route targets
for a particular VRF, but then configuring nonidentical route distinguisher across multiple PE
devices?

Tesla Radio GmbH is going to build a new research lab network based on a set of switches that
would connect to their existing enterprise network. They are considering a design that would
guarantee loop-free behavior within the set of switches. The design would also allow the groupof switches to seem like a single switch to the enterprise network, because it is owned by a
separate administrative group. Which Spanning Tree Protocol should be used to support the
design requirements?

Youare designing a Group Encrypted TransportVirtual Private Network solution consisting of 30
group members. Which measure helps protect encrypted user traffic from replay attacks?

If a network design must support rapid convergence on half-duplex interfaces, which IEEE
802.1w capability should be used?

When creating a design plan for IPv6 integration, you decide to use stateless encapsulation of
IPv6 packets into IPv4 tunnels between subscriber CPEs and a border relay. Which deployment
technique allows for this functionality?

Which mechanism should be added to a network design to identify unidirectional Spanning
Tree Protocol failures through BPDU loss?
