A. OSPF over multicast EMS or VPLS network may not have consistent broadcast or multicastperformance
B. IP multicast is not supported over Lover 3 MPLS VPN； instead a Layer 2 MPLS WN must beutilized with service provider support
C. QoS requirements with MPLS-VPN must be implemented by the service provider
D. Hierarchical VPLS designs are the least scalable
E. IGMP snooping is not on option with VPLS or EMS； instead administrative scoping or allowingsufficient bandwidth for unnecessary multicast traffic at the edge links is required

D. OSPF totally stubby cannot distinguish among ABRs for the best route to destinationsoutsidethe areas
E. OSPF stub areas can distinguish among ASBRs for destinations that are external to the OSPFdomain
A. IDS is capable of both inline and promiscuous monitoring， while IPS is only capable ofpromiscuous monitoring
B. IDS will stop malicious traffic from reaching its intended target for certain types of attacks.
C. IPS processes information on Layer 3 and 4 as well as analyzing the contents and payload ofthe packets for more sophisticated embedded attacks （Layers 3 to 7）
D. IPS inspects traffic statefully and needs to see both sides of the connection to function properly
E. IDS placement at the perimeter of Data Center outside the firewall generates many warningsthat have relatively low value because no action is likely to be taken on this information
