   How do graph queries differ from traditional SQL queries in the context of network analytics?

   • AGraph queries are only used for real-time data, while SQL queries are used for historical data.
   • BGraph queries focus on relationships between entities, while SQL queries focus on data stored in tables.
   • CGraph queries are written in a declarative language, while SQL queries are written in a procedural language.

   A junior engineer is learning about the data model for their network analytics platform. They ask why the platform uses a graph database instead of a traditional relational database. Which explanation is most accurate?

   • AA graph database makes it easier to evolve the data model as new network elements and relationships are added.
   • BA graph database is required to store data in JSON format.
   • CA graph database eliminates the need for any indexing.
   • DA graph database is always faster than a relational database for any query.

   A large data center has a multi-tier application. The operations team is using a graph database to model the application's dependencies. They run a query to find all components that depend on a specific database cluster. The query returns a large number of components, including some that are in a different tenant and should not be impacted. The team suspects the query is too broad. What is the most likely reason for this over-inclusive result?

   • AThe query did not filter by tenant, and the graph model includes relationships that cross tenant boundaries.
   • BThe graph database is corrupted and returning incorrect results.
   • CThe query is using the wrong relationship type.
   • DThe query is returning all paths, not just the shortest path, and some paths go through other tenants.

   A network operator wants to identify all switches that are directly connected to a specific server. Which type of graph query would be most appropriate for this troubleshooting scenario?

   • AA query that matches the server node and traverses one hop to find connected switch nodes.
   • BA query that returns all devices in the network with their interface counts.
   • CA query that calculates the average latency between all pairs of devices.
   • DA query that lists all configuration changes made in the last 24 hours.
