In BGP routing，what does the rule of synchronization mean？（）

• A、A BGP router can only advertise an EBGP learned route，provided that the route is an IGP route in the routing table.
• B、A BGP router can only advertise an IBGP learned route，provided that the route is an IGP route in the routing table.
• C、A BGP router can only advertise an IBGP learned route，provided that the route is an IGP route that is not in the routing table.
• D、A BGP router can only advertise an EBGP learned route，provided that the route is a metric of 0 in the BGP table.

SR7750调测BGP邻居状态变化的命令是（）

• A、debug router bgp open

第5题：

You have a router running BGP for the MPLS network and OSPF for the local LAN network at the sales office. A route is being learned from the MPLS network that also exists on the OSPF local network. It is important that the router chooses the local LAN route being learned from the downstream switch running OSPF rather than the upstream BGP neighbor. Also， if the local OSPF route goes away， the BGP route needs to be used. What should be configured to make sure that the router will choose the LAN network as the preferred path？（）

• A、static route needs to be added
• B、floating static route needs to be added
• C、bgp backdoor command
• D、ospf backdoor command

You issue the command show process memory ∣ include BGP and notice that BGP is consuming alarge percentage of the router’s memory. Which of the following steps would result in lowering theamount of memory being consumed by BGP？（Choose all that apply.）（）

• A、Filter unneeded BGP routes
• B、Run BGP on a different platform that already has more memory
• C、Upgrade the router memory
• D、Increase the BGP update timer
• E、Compress the BGP table
• F、Use a default route instead of maintaining a full BGP table

第9题：

When BGP is used as the PE-CE routing protocol, which of these statements is correct?（）

• A、On the CE router, PE neighbors must be configured in the VRF context on the CE router
• B、On PE routers, the CE IBGP neighbors are configured in the global BGP configuration
• C、On PE routers, the CE EBGP neighbors are configured in the VRF context
• D、A separate BGP process must be used on the PE routers for CE routers so that they do not use the same BGP routing process as that used for the PE router's other provider neighbors

第10题：

Two routers configured to run BGP have been connected to a firewall， one on the inside interface and one on the outside interface. BGP has been configured so the two routers should peer， including the correct BGP session endpoint addresses and the correct BGP session hop-count limit （EBGP multihop）. What is a good first test to see if BGP will work across the firewall？（）

• A、Attempt to TELNET from the router connected to the inside of the firewall to the router connected to the outside of the firewall. If telnet works， BGP will work， since telnet and BGP both use TCP to transport data.
• B、Ping from the router connected to the inside interface of the firewall to the router connected to the outside interface of the firewall. If you can ping between them， BGP should work， since BGP uses IP to transport packets.
• C、There is no way to make BGP work across a firewall without special configuration， so there is no simple test that will show you if BGP will work or not， other than trying to start the peering session.
• D、There is no way to make BGP work across a firewall.
