After the recent implementation of a new design that incorporated GRE tunnels into the
network, the network operations staff is seeing the following syslog message in multiple
routers on the network – %TUN-5-RECURDOWN: Tunnel0 temporarily disabled due to recursive
routing.
From a design perspective, what was not taken into account prior to implementing the
solution?

You are asked to design a large campus network that will be using multicast for data transport.
Which feature should be enabled at the Layer 2 access edge for host-only ports?

Which two features can be used to extend VRFs across a campus? (Choose two.)

Which technique can you use to detect forwardingpath failures at a uniform rate, and
reconvergencetimes will be consistent and predictable when your routersare in the same
broadcast domain?

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 therecently 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?

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.)

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

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?
