A company wants a design that would support OSPF through a service provider ATM network.
Which two OSPF network types should the designer use to establish OSPF neighborship
between OSPF routers through the ATM network? (Choose two.)

Youare designing the QoS features for a large enterprise network that includes DMVPN. When
would you need to configure QoS preclassify?

A green data center is being deployed and a design requirement is to be able to readily scale
server virtualization. Which IETF standard technology can provide this requirement?

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?
