第5题：

What does the OSPF command capability vrf-lite achieve？（）

• A、It enables provider edge （PE） specific checks on a router when the OSPF process is associated with the VRF
• B、It disables provider edge （PE） specific checks on a router when the OSPF process is associated with the VRF
• C、It enables the exchange of the "VRF-Lite" capability when the OSPF adjacency is formed.
• D、It disables the MPLS processing on the OSPF learned routes inside the VRF

第6题：

When the Cisco IOS OSPF command ip ospf dead-interval minimal hello-multiplier 5 is configured， which two statements are true？ （）

• A、OSPF hello interval is 5 seconds
• B、OSPF hello interval is 1 second
• C、OSPF dead interval is 1 second
• D、OSPF dead interval is 5 seconds

第7题：

When designing the routing for an Enterprise Campus network it is important to keep while of thefollowing filtering aspects in mind？（）

• A、 Filtering is only useful when combined with route summarization
• B、 It is best to filter （allow） the default and summary prefixes only in the Enterprise Edge to remotesites or site-to-site IPsec VPN networks
• C、 IGPs （for example EIGRP or OSPF） are superior to route filtering in avoiding in inappropriatetransit traffic through remote nodes or inaccurate or inappropriate routing updates
• D、 The primary limitation of router filtering is that it can only be applied on outbound updates

• C、OSPF routes cannot be exported into EIGRP, RIP, an d IS - IS.
• D、At the interdomain level, OSPF cannot import routes learned using BGP.
• E、OSPF routes can be exported into BGP.
