第5题：

Which two restrictions must the Enterprise Campus network designer consider when evaluatingWAN connectivity options？ （）

• A、 OSPF over multicast EMS or VPLS network may not have consistent broadcast or multicastperformance

第8题：

What is an important step to take when verifying a newly proposed network security solution？ （）

• A、Test the design on a pilot network for expected results prior to implementing on the production network.
• B、Run a network audit to determine types of traffic in use on the network.
• C、Launch campus updates into the production network and monitor impact to see if configuration changes are needed.

第9题：

Multicast is being deployed in the network， and only ip pim sparse-dense mode has been configured on all interfaces in the network to support a new video streaming application. No other multicast configuration was applied anywhere in the network. Since enabling multicast， the network monitoring tools show periodic spikes in link utilization throughout the network， even in areas where the video application is not being used. What could be a possible cause？（）

• A、PIM sparse mode is being used.
• B、PIM dense mode is being used.
• C、The BGP multicast address family has not been configured.
• D、IGMP version 3 is being used.
• E、IP PIM neighbor filters have not been applied.

第10题：

What is the purpose of a rendezvous point (RP)?（）

• A、acts as a meeting place for sources and receivers of multicast traffic
• B、used in PIM dense m ode to create a database of all multicast sources
• C、used in PIM dense and sparse mode to create a database of all multicast sources
• D、acts as the designated router for a broadcast segment when multicast routing is enabled
