Which of the following IP addresses can be used by another host to communicate with the host whose IP address is 200.200.200.201/30 without the need to forward traffic through a router?
Correct : C
Detailed
The subnet 200.200.200.200/30 allows two usable IP addresses, 200.200.200.201 and 200.200.200.202. These two addresses can communicate with each other directly, without the need for routing .

What are the advantages of OSPF?
Correct : A, B, C, D
Detailed
OSPF (Open Shortest Path First) has several key advantages:
It can load balance traffic among equal-cost routes.
OSPF supports hierarchical area structures, allowing for network scalability and reduced routing table sizes.
OSPF supports strong security measures through packet authentication (MD5 or plain text).
It supports Classless Inter-Domain Routing (CIDR), allowing for more efficient IP address allocation and route aggregation.

In RSTP, an edge port becomes a common STP port after receiving a configuration BPDU.
Correct : A
Detailed
In RSTP (Rapid Spanning Tree Protocol), if an edge port receives a BPDU (Bridge Protocol Data Unit), it loses its edge status and becomes a regular STP port. This ensures that the edge port behaves as expected when connecting to another switch.

Which of the following MAC addresses cannot be used as the MAC address of host network adapters?
Correct : C
Detailed
MAC addresses that start with the first octet having the least significant bit (LSB) of the first byte set to 1 (such as 01-02-03-04-05-06) are multicast MAC addresses, and these cannot be assigned to a host's network interface card (NIC). Only unicast MAC addresses can be assigned to hosts.
