If technology migration on the network affects the services running on the live network, strictly follow the preset operation process and risk control measures during the implementation of the technology migration project. Generally, this type of project is defined as a migration project. Which of the following operations performed on the live network belongs to a non-migration project?

Modifying the description of router interfaces in batches

Modifying the description of router interfaces in batches

OSPF requires that routers in the same area have the same link state database (LSDB). As the number of routes on the network increases, some routers cannot carry so much routing information due to limited system resources. This state is called database overflow. If the Isdb-overflow-limit number 7 command is run on all routers on an OSPF network, which of the following conditions are likely to cause routers to enter the overflow state?

The number of Type 5 LSAs exceeds 7.

The number of Type 4 LSAs exceeds 7.

The number of Type 5 LSAs exceeds 7.

The number of Type 7 LSAs exceeds 7.

The number of Type 3 LSAs exceeds 7.
