Neo4j GDS Certification Practice Questions - Neo4j Graph Data Science Certification Exam - Neo4j GDS Certification Practice Questions - Neo4j Graph Data Science Certification Exam

Question 1

Which GDS procedure creates a native projection of nodes labeled 'Person' and 'KNOWS' relationships?

CALL gds.graph.project('myGraph', 'Person', 'KNOWS') CALL gds.graph.create('myGraph', 'Person', 'KNOWS') CALL gds.project.graph('myGraph', 'Person', 'KNOWS') CALL gds.native.project('myGraph', 'Person', 'KNOWS')

Correct Answer:

CALL gds.graph.project('myGraph', 'Person', 'KNOWS')

Question 2

What is the key difference between a native projection and a Cypher projection in GDS?

Native projections use pre-existing graph schema for fast loading; Cypher projections use custom Cypher queries for flexibility Native projections require schema indexes; Cypher projections work on any graph Native projections only support directed graphs; Cypher projections support both Native projections store data on disk; Cypher projections keep data in memory

Correct Answer:

Native projections use pre-existing graph schema for fast loading; Cypher projections use custom Cypher queries for flexibility

Question 3

Which GDS execution mode returns results row-by-row and does NOT write back to Neo4j?

stream stats mutate write

Correct Answer:

stream

Question 4

After running `CALL gds.pageRank.mutate('myGraph', {mutateProperty: 'score'})`, where is the 'score' property stored?

In the in-memory projected graph only Written to Neo4j node properties immediately Written to a GDS catalog result set Stored in a temporary on-disk file

Correct Answer:

In the in-memory projected graph only

Question 5

Which Cypher correctly streams PageRank scores for all nodes in a named graph?

CALL gds.pageRank.stream('myGraph') YIELD nodeId, score RETURN gds.util.asNode(nodeId).name AS name, score ORDER BY score DESC CALL gds.pageRank.run('myGraph') YIELD nodeId, score RETURN nodeId, score CALL gds.algorithms.pageRank('myGraph') YIELD nodeId, score RETURN nodeId, score MATCH (n) CALL gds.pageRank.stream(n) YIELD score RETURN n.name, score

Correct Answer:

CALL gds.pageRank.stream('myGraph') YIELD nodeId, score RETURN gds.util.asNode(nodeId).name AS name, score ORDER BY score DESC
