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?

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?

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?

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 the QoS features for a large enterprise network that includes DMVPN. When

would you need to configure QoS preclassify?

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.)

Which restriction prevents a designer from using a GDOI-based VPN to secure traffic that
traverses the Internet?

A company is planning to connect its 30 sites with a VPLS WAN backbone. A router at each site
should establish neighborships with all other routers using the OSPF routing protocol. Which three
points must be considered regarding DR and BDR when different router platforms are used?
(Choose three.)

A network administrator is in charge of multiple IPsec VPN headend devices that service
thousands of remote connectivity, point-to-point, IPsec/GRE tunnels. During a recent power
outage, in which it was found that a backup power supply in one of those headend devices was
faulty, one of the headend routers suffered a complete shutdown event. When the router was
successfully recovered, remote users found intermittent connectivity issues that went away after
several hours. Network operations staff accessed the headend devices and found that the recently
recovered unit was near 100% CPU for a long period of time. How would you redesign the network
VPN headend devices to prevent this from happening again in the future?

Which technique can you use to detect forwarding path failures at a uniform rate, and
reconvergence times will be consistent and predictable when your routers are in the same
broadcast domain?
