To answer this question, let's go through each option to understand why it is correct or incorrect:
Option A) Reduces convergence time - This option is correct. Link-State routing protocols, such as OSPF (Open Shortest Path First) and IS-IS (Intermediate System to Intermediate System), use the shortest path first algorithm to calculate the best path for each destination. This allows for faster convergence, meaning that the network can quickly adapt to changes in the topology.
Option B) Allows for a larger scalable network - This option is correct. Link-State routing protocols can scale well in large networks. They maintain a detailed map of the network topology, which allows for efficient path calculation and scalability.
Option C) Allows for a larger scalable network - This option is correct. This is a duplicate of option B.
Option D) Allows the use of a more robust addressing scheme - This option is correct. Link-State routing protocols support the use of hierarchical addressing schemes, such as Classless Inter-Domain Routing (CIDR), which allows for efficient allocation and utilization of IP addresses.
Based on the explanations above, the correct answer is E) all of the above. All of the options listed are benefits of a Link-State routing protocol.
