第5题：

Which of the following is true regarding the effect of EIGRP queries on the network design？（）

• A、 EIGRP queries will be the most significant issue with respect to stability and convergence 
• B、 EIGRP queries are not a consideration as long as EIGRP has a feasible successor with a nexthop AD that is greater than the FD of the current successor route 
• C、 EIGRP queries will only increase the convergence time when there are no EIGRP stubsdesigned in the network

• A、OSPF external LSAs are automatically flooded into all OSPF areas， unlike type 7 LSAs， which require that redistribution be configured.
• B、External LSAs （type 5） are automatically changed to type 1 LSAs at ASBRs.
• C、Type 5 LSAs are route summaries describing routes to networks outside the OSPF Autonomous System.
• D、External network LSAs （type 5） redistributed from other routing protocols into OSPF are not permitted to flood into a stub area.
