Which database engine meets these requirements?

Explanations:

Amazon Aurora MySQL is a relational database suitable for transactional workloads but lacks the graph capabilities needed for complex network visualizations and rapid querying of interconnected data.

Amazon Neptune is a fully managed graph database service that supports both property graph and RDF graph models, making it ideal for storing and querying network components, routes, and relationships efficiently. Its capabilities enable rapid querying of complex relationships and paths, which is essential for the application’s requirements.

Amazon ElastiCache for Redis is an in-memory data store primarily used for caching and real-time data processing. While it provides fast data access, it does not offer structured querying capabilities for complex relationships between networking components, which is needed for identifying routes and redundancy.

Amazon DynamoDB is a NoSQL database that offers high scalability and performance for key-value and document data. However, it is not optimized for graph-based queries needed to evaluate networks and routes, making it less suitable for the application’s requirements compared to a graph database like Neptune.
