Sample Banco do Brasil Agente de Tecnologia Practice Questions

Try these sample questions to test your Banco do Brasil Agente de Tecnologia exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1In Java 17, a software engineer at Banco do Brasil is designing a payment processing module where a base class 'PaymentProcessor' defines a method 'public void process(Transaction tx)'. A subclass 'PixProcessor' overrides this method. At runtime, when an instance of 'PixProcessor' is referenced via a variable of type 'PaymentProcessor' and 'process(tx)' is invoked, which mechanism determines that the 'PixProcessor' implementation must execute?

A.Dynamic method dispatch (late binding) resolved at runtime via the virtual method table (vtable)

B.Static method binding resolved at compile time based on the reference type 'PaymentProcessor'

C.Bytecode weaving performed by the Java Native Interface (JNI) during class loading

D.Type erasure performed by the Java compiler during bytecode generation

Explanation: Dynamic method dispatch (or late binding) is the mechanism by which a call to an overridden method is resolved at runtime rather than compile time. In the JVM, virtual method invocation (invokevirtual) inspects the actual object type in the heap using its vtable to execute the subclass's overridden implementation. This forms the foundational basis of subtype polymorphism in Java.

2A banking system requires constructing complex 'LoanProposal' objects with varying attributes such as applicant rating, collateral items, guarantor data, and repayment schedules. Which GoF design pattern separates the construction of this complex object from its representation, allowing the same construction process to create various representations?

A.Builder Pattern

B.Prototype Pattern

C.Abstract Factory Pattern

D.Decorator Pattern

Explanation: The Builder pattern separates the construction of a complex object from its representation, allowing step-by-step object configuration and preventing 'telescoping constructors'. It is especially useful in financial applications where entity objects have numerous optional and required parameters. Prototype creates copies of existing objects, Abstract Factory produces families of related objects, and Decorator adds dynamic behaviors.

3A developer at Banco do Brasil refactors a monolithic 'AccountService' class that previously calculated interest, persisted database records, formatted PDF statements, and sent SMS alerts. By decomposing this class into 'InterestCalculator', 'AccountRepository', 'StatementGenerator', and 'NotificationService', which SOLID principle is most directly applied?

A.Single Responsibility Principle (SRP)

B.Open/Closed Principle (OCP)

C.Liskov Substitution Principle (LSP)

D.Interface Segregation Principle (ISP)

Explanation: The Single Responsibility Principle (SRP) states that a class should have one, and only one, reason to change. By splitting disparate responsibilities (business calculation, data persistence, reporting, and external messaging) into dedicated classes, each class gains a single, well-defined cohesion boundary.

4When working on a feature branch 'feat/pix-keys' in Git, a developer wants to incorporate the latest commits from 'main' while keeping a completely linear commit history without creating an extra merge commit. Which Git command should be executed?

A.git rebase main

B.git merge --no-ff main

C.git cherry-pick --abort

D.git revert HEAD

Explanation: The command 'git rebase main' replays the commits of the current branch ('feat/pix-keys') on top of the tip of the 'main' branch, resulting in a linear project history without merge commits. This prevents cluttered history graphs when adhering to rebase workflows.

5Consider the following Java Streams pipeline intended to calculate the total transaction volume for approved credit operations: ```java BigDecimal total = transactions.stream() .filter(t -> t.getStatus() == Status.APPROVED) .map(Transaction::getAmount) .reduce(BigDecimal.ZERO, BigDecimal::add); ``` What is the nature of the operations 'filter' and 'reduce' in this pipeline?

A.'filter' is an intermediate lazy operation, while 'reduce' is a terminal eager operation.

B.'filter' is a terminal operation, while 'reduce' is an intermediate lazy operation.

C.Both 'filter' and 'reduce' are intermediate lazy operations.

D.Both 'filter' and 'reduce' are terminal eager operations.

Explanation: In Java Streams, stream operations are divided into intermediate and terminal operations. Intermediate operations (such as filter, map, sorted) return a new Stream, are lazy, and do not execute until a terminal operation is invoked. Terminal operations (such as reduce, collect, forEach) traverse the pipeline, produce a final non-stream result, and close the stream.

6In a Scrum framework operating within Banco do Brasil's Digital Banking division, what is the primary purpose of the Daily Scrum meeting?

A.To inspect progress toward the Sprint Goal and adapt the Sprint Backlog as necessary.

B.To negotiate and modify the product vision and contract scope with external stakeholders.

C.To conduct a detailed technical architecture review of all system pull requests.

D.To evaluate individual developer performance metrics for quarterly bonus allocation.

Explanation: According to the Scrum Guide, the primary purpose of the Daily Scrum is for Developers to inspect progress toward the Sprint Goal and adapt the Sprint Backlog as necessary, adjusting upcoming planned work. It is a 15-minute time-boxed event for internal team alignment.

7In Python 3, which of the following built-in data types is immutable and suitable for use as a dictionary key?

A.tuple containing only integers and strings

B.list containing integers

C.set containing string elements

D.bytearray containing raw payload bytes

Explanation: Dictionary keys in Python must be hashable, which requires that they are immutable and have a constant hash value throughout their lifetime. A tuple containing only immutable objects (like integers and strings) is immutable and hashable. In contrast, lists, sets, and bytearrays are mutable data structures and cannot be used as dictionary keys (they raise TypeError: unhashable type).

8According to RFC 7231 / RFC 9110, which HTTP method is defined as idempotent and intended to completely replace the target resource's current representation with the uploaded payload?

A.PUT

B.POST

C.PATCH

D.CONNECT

Explanation: PUT is an idempotent HTTP method designed to create or completely replace the state of the resource identified by the Request-URI. Making multiple identical PUT requests must produce the same side effect as a single request. POST is not idempotent, PATCH is intended for partial modifications and is not inherently idempotent by specification, and CONNECT establishes a tunnel to a server.

9In Test-Driven Development (TDD), what is the correct chronological sequence of steps in the core development cycle?

A.Write a failing unit test -> Write minimal code to pass the test -> Refactor the code

B.Write production code -> Write integration tests -> Refactor production code

C.Refactor existing code -> Write automated end-to-end test -> Fix production bugs

D.Write all application interfaces -> Implement mock classes -> Write regression assertions

Explanation: The core TDD cycle follows the 'Red-Green-Refactor' methodology: (1) Red: write a concise unit test that fails because the feature does not yet exist; (2) Green: write the simplest, minimal code that makes the test pass; (3) Refactor: clean up the code, eliminating duplication and enhancing readability while keeping all tests passing.

10In a continuous integration and continuous delivery (CI/CD) pipeline for a core banking service, what is the primary objective of the 'Continuous Integration' (CI) phase?

A.Automatically merging developer code changes into a shared repository, followed by automated building and testing.

B.Provisioning production Kubernetes clusters on demand without developer intervention.

C.Deploying the built binaries directly to production customer-facing servers upon every commit.

D.Manually conducting business acceptance testing and signing off regulatory audit reports.

Explanation: Continuous Integration (CI) is a software development practice where developers frequently integrate their code changes into a central repository, after which automated builds and automated test suites run to detect integration errors as quickly as possible. Continuous Delivery/Deployment (CD) extends this by automating release staging and deployment.
