s about "The Complete Neo4j Java Driver 2026: From Zero to Expert!" for a course on "Neo4j Drivers & APIs Mastery Hub": Question: When using the Neo4j Java Driver 2026, which of the following best describes the primary advantage of employing the `Transaction.runAsync()` method over `Transaction.run()` for long-running or potentially blocking operations?
`runAsync()` returns a `CompletionStage` which allows for non-blocking asynchronous handling of the query result, preventing the driver thread from being held up.
`runAsync()` is optimized for read-heavy workloads and provides significantly lower latency compared to synchronous operations.
`runAsync()` guarantees immediate execution without any potential for thread blocking, ensuring optimal performance.
`runAsync()` automatically handles transaction retries and error propagation, simplifying error management for developers.

In the context of the Neo4j Java Driver 2026's connection pooling mechanism, what is the fundamental difference between `ConnectionAcquisitionTimeout` and `ConnectionTimeout`?
`ConnectionAcquisitionTimeout` refers to the time the driver waits to establish a new connection to the Neo4j instance, while `ConnectionTimeout` is the maximum time a client application can hold a connection from the pool.
`ConnectionAcquisitionTimeout` is the time limit for resolving the Neo4j host and port, while `ConnectionTimeout` is the duration the driver will attempt to establish a TCP connection to the resolved address.
`ConnectionAcquisitionTimeout` dictates the maximum time a thread will wait for a connection to become available from the pool, whereas `ConnectionTimeout` is the server-side setting for how long a database connection can remain idle.
`ConnectionAcquisitionTimeout` is a client-side setting for acquiring an existing connection from the pool, and `ConnectionTimeout` is a client-side setting for the initial handshake with the Neo4j server.

The Neo4j Java Driver 2026 introduces a new `BookmarkManager` interface. What is the primary purpose of implementing a custom `BookmarkManager` for distributed or highly available Neo4j deployments?
To automatically synchronize bookmarks between different Neo4j clusters, ensuring consistency in read operations across geographically distributed data.
To inject custom logic for validating bookmark integrity before they are used to ensure data consistency in the event of network partitions.
To optimize query execution plans by caching frequently used bookmarks, thereby reducing database load.
To provide a centralized, persistent, and fault-tolerant mechanism for storing and retrieving bookmarks across multiple driver instances and Neo4j replicas.
