On an OSPF network, an algorithm is used to prevent loops within an area, but loops may occur between areas. Therefore, OSPF defines a loop prevention mechanism for inter-area routes. Which of the following statements are true about the loop prevention mechanism?

Inter-area routes cannot be directly transmitted between non-backbone areas.

All non-backbone areas must be directly connected to area 0.

Inter-area routes need to be forwarded through area 0.

An ABR cannot inject Type 3 LSAs that describe routes to a network segment in an area back to the same area.

Inter-area routes cannot be directly transmitted between non-backbone areas.

All non-backbone areas must be directly connected to area 0.

Inter-area routes need to be forwarded through area 0.

The following figure shows the OSPF network of an enterprise and the OSPF configurations of R1. Which of the following statements is false about the network?

The network segment to which GE 0/0/1 of R1 belongs cannot be advertised.

GE 0/0/1 of R1 cannot send OSPF packets.

The network segment to which GE 0/0/1 of R1 belongs cannot be advertised.

GE 0/0/1 of R1 cannot accept OSPF packets.

If the export routing policy applied to a BGP peer changes, manual intervention is required so that the device resends Update messages to the peer.

IGP routes can be converted into BGP routes only through the network command.

A router cannot be configured with multiple BGP processes.

Open messages carry only the BGP header.

After receiving a configuration BPDU, the port is still in the Forwarding state.

The port does not participate in RSTP calculation.

The port can directly enter the Forwarding state from the Discarding state.

After receiving a configuration BPDU, the port is still in the Forwarding state.

The Up and Down states of the port do not cause network topology changes.
