1What are the two fundamental data entities in the Neo4j property graph model?

A.Tables and rows

B.Nodes and relationships

C.Documents and collections

D.Keys and values

Explanation: Neo4j uses the property graph model built on two primary entities: nodes (which represent entities) and relationships (which represent connections between entities). Both nodes and relationships can have properties (key-value pairs) and nodes have labels while relationships have types. Tables/rows belong to the relational model, documents to NoSQL, and key-value is a different store model.

2In Cypher, which syntax correctly matches a node with the label Person?

A.MATCH [p:Person] RETURN p

B.MATCH {p:Person} RETURN p

C.MATCH (p:Person) RETURN p

D.MATCH <p:Person> RETURN p

Explanation: In Cypher, nodes are enclosed in parentheses (). Square brackets [] are used for relationships, curly braces {} for property maps, and angle brackets < > denote relationship direction (as part of -[]-> or <-[]-). So MATCH (p:Person) RETURN p is the correct syntax.

3Which Cypher pattern represents a directed relationship from node a to node b with type KNOWS?

A.(a)-[:KNOWS]-(b)

B.(a)-[:KNOWS]->(b)

C.(a)=[:KNOWS]=>(b)

D.(a).[:KNOWS].(b)

Explanation: Cypher uses arrow notation to express direction. A dash-bracket-arrow pattern like -[:KNOWS]-> indicates a directed relationship from left to right. Using just -[:KNOWS]- (no arrow) matches an undirected pattern (either direction). The equals sign and dot-bracket forms are not valid Cypher syntax.

4What does the following Cypher query return? MATCH (p:Person {name: 'Alice'})-[:FRIEND]->(friend) RETURN friend.name

A.The names of all Person nodes in the database

B.The names of people who are friends of Alice

C.The names of people who have Alice as a friend

D.Alice's own name

Explanation: The pattern matches Alice via the inline property filter {name: 'Alice'}, then follows outgoing FRIEND relationships to friend nodes, and returns friend.name. Since the arrow points away from Alice, the result is people Alice considers friends (outgoing direction). Reversing the arrow to <- would give people who list Alice as their friend.

5Which Cypher clause creates a new node only if a matching one does not already exist?

A.CREATE

B.MERGE

C.INSERT

D.UPSERT

Explanation: MERGE is Cypher's match-or-create operation. It first tries to match the given pattern and only creates the pattern if no match exists, making it idempotent. CREATE always creates a new node even if an identical one exists. INSERT and UPSERT are not Cypher keywords (UPSERT belongs to SQL dialects).

6What is the correct Cypher to delete a node and all of its relationships in a single statement?

A.MATCH (n:Person {name: 'Alice'}) DELETE n

B.MATCH (n:Person {name: 'Alice'}) REMOVE n

C.MATCH (n:Person {name: 'Alice'}) DETACH DELETE n

D.MATCH (n:Person {name: 'Alice'}) DROP n

Explanation: DETACH DELETE deletes a node together with all of its relationships atomically. A plain DELETE on a node with relationships will throw an error because Neo4j refuses to leave dangling relationships. REMOVE is for labels and properties, not nodes. DROP is not a Cypher delete keyword (it applies to indexes, constraints, databases).

7What is a 'label' in Neo4j terminology?

A.A property key on a relationship

B.A type marker attached to a node to group nodes of the same kind

C.The unique identifier (id) of a node

D.A visual color assigned in Neo4j Browser

Explanation: A label is a marker attached to a node to classify it (e.g., :Person, :Movie). Nodes can have zero, one, or multiple labels. Labels make queries more efficient because they let Neo4j narrow the search space. Relationships have 'types', not labels. The internal node id is separate from labels.

8Which is true about relationships in Neo4j?

A.Relationships must always be directed; they cannot be undirected

B.A relationship can have multiple types at the same time

C.Relationships can have properties, like nodes can

D.Relationships connect only one node to itself

Explanation: Relationships in Neo4j can store properties (e.g., {since: 2020}) just like nodes can. Every relationship in Neo4j has exactly one type and is stored as directed in the data, though you can query it in either direction. Relationships connect two nodes (possibly the same node via a self-loop).

9Which Cypher clause is used to filter results after a MATCH?

A.HAVING

B.WHERE

C.FILTER

D.RESTRICT

Explanation: Cypher uses WHERE to filter patterns and rows, similar to SQL. HAVING does not exist in Cypher (group-level filters are handled in WITH...WHERE). FILTER was an older list comprehension form replaced by list comprehensions [x IN list WHERE ...]. RESTRICT is not a Cypher keyword.

10How do you pass the variable $name into a Cypher query using a parameter?

A.MATCH (p:Person) WHERE p.name = name RETURN p

B.MATCH (p:Person) WHERE p.name = $name RETURN p

C.MATCH (p:Person) WHERE p.name = @name RETURN p

D.MATCH (p:Person) WHERE p.name = :name RETURN p

Explanation: Cypher parameters are referenced with a leading $ sign (e.g., $name). Parameters improve performance (plan cache reuse) and security (prevents Cypher injection). Neither @ nor : are used for parameters in Cypher. A bare name without $ would be treated as a variable and likely fail.

Neo4j Certified Professional Study Tips from Top Performers

1Master the basic Cypher pattern syntax — parentheses for nodes, square brackets for relationships, arrows for direction

2Understand the difference between CREATE and MERGE — MERGE is a match-or-create idempotent operation

3Know when to use WITH to chain query parts and scope variables, especially before aggregations

4Practice OPTIONAL MATCH for left-join semantics and handling missing patterns

5Remember that UNIQUE, NODE KEY, and EXISTENCE constraints are distinct — NODE KEY combines uniqueness and existence

6Study the APOC library basics (apoc.load.json/csv, apoc.path.expand) and GDS core algorithms (PageRank, Louvain, Node2Vec)

7Use PROFILE and EXPLAIN to read query plans and identify missing indexes
