An enterprise network has two core routers that connect to 200 distribution routers and uses fullmesh IBGP peering between these routers as its routing method. The distribution routers are experiencing high CPU utilization due to the BGP process. Which design solution is the most cost effective?
Implement route reflectors on the two core routers
Increase the memory on the core routers
Implement e BGP between the core and distribution routers
Increase the memory on the distribution routers
Increase bandwidth between the core routers

How can EIGRP topologies be designed to converge as fast as possible in the event of a point-topoint link failure?
Limit the query domain by use of distribute lists.
Build neighbor adjacencies in a triangulated fashion.
Build neighbor adjacencies in squared fashion.
Limit the query domain by use of summarization.
Limit the query domain by use of default routes.
Which effect of using ingress filtering to prevent spoofed addresses on a network design is true?
It reduces the effectiveness of DDoS attacks when associated with DSCP remarking to Scavenger.
It protects the network Infrastructure against spoofed DDoS attacks.
It Classifies bogon traffic and remarks it with DSCP bulk.
It filters RFC 1918 IP addresses.
Which relationship between IBGP and the underlying physical topology is true?
iBGP full mesh requirement does not dictate any specific network topology.
iBGP can worn only on a ring network topology with a link-state protocol like OSPF or IS-IS
iBGP full mesh requires an underlying fully meshed network topology.
iBGP does not work on a ring network topology even with an underlying IGP.

Traffic was equally balanced between Layer 3 links on core switches SW1 and SW2 before an introduction of the new video server in the network. This video server uses multicast to send video streams to hosts and now one of the links between core switches is over utilized Which design solution solves this issue?
Add more links between core switches.
Aggregate links Layer 2 link aggregation.
Apply a more granular load- balancing method on SW1.
Apply a more granular load-balancing method on SW2.
Filter IGMP joins on an over -utilized link.
