TRUE

FALSE

NEW QUESTION 44
Which of the following description of the OSPF default route is false?

OSPF routing can be issued by the area border router (ABR) Type3 default Summary LSA, used to guide the routers in the area to forward packets between areas

When the router does not have an exact matching route, it can forward packets through the default route

Due to the hierarchical management of OSFP routing, the priority of Type5/7 missing routing is higher than Type3 routing

NEW QUESTION 64
In a certain network environment, there are both switches running RSTP and switches running SIP. What will happen to the network? (Multiple choice)

If it is a Huawei switching equipment, RSTP will switch to STP mode. After the STP switching equipment is evacuated from the network, the switching equipment running RSTP can be migrated back to the RSTP working mode

RSTP can interoperate with STP, but the advantages of RSTP such as rapid convergence are lost at this time

RSTP and STP are not interoperable and will perform independent operations
