In which collaboration tool can developers create and manage branches for implementing new features or fixing bugs?
- Bitbucket
- Git
- Jira
- Trello
Bitbucket is a collaboration tool that allows developers to create and manage branches for implementing new features or fixing bugs. It is particularly known for its integration with Git and providing version control capabilities.
Which branching strategy encourages developers to create feature branches off the main branch for each new feature?
- Feature Branching
- Forking Workflow
- Git Flow
- Trunk-Based Development
The branching strategy that encourages creating feature branches off the main branch for each new feature is known as "Git Flow." It promotes a structured approach to managing features, releases, and hotfixes in a Git repository.
What is the primary goal of authentication?
- Authorizing access to resources
- Confirming the identity of a user
- Ensuring data integrity
- Validating network connectivity
The primary goal of authentication is to confirm the identity of a user. It verifies that the user is who they claim to be before granting access to resources or systems.
Enabling _______ compression can reduce the size of files transferred over the network, improving overall performance.
- Gzip
- RAR
- Tar
- ZIP
Enabling Gzip compression is a common practice to reduce the size of files transferred over the network. Gzip compresses files before sending them, reducing bandwidth usage and improving overall performance.
Among the options, which language is often associated with the server-side environment in a Node.js application?
- Java
- JavaScript
- Python
- Ruby
JavaScript is often associated with the server-side environment in a Node.js application. Node.js enables server-side scripting using JavaScript.
The HTTP _______ status code is used to indicate that the requested resource could not be found.
- 200
- 302
- 404
- 500

In database systems, a _______ is a mechanism to control access to data items by multiple transactions.
- Buffer
- Lock
- Semaphore
- Trigger
In database systems, a lock is a mechanism used to control access to data items by multiple transactions. It helps in preventing conflicts and ensuring the consistency of the data during concurrent access. Locks can be applied at various levels, such as row-level, page-level, or table-level.
In _______ caching, data is stored closer to the end-user to reduce latency.
- Client-Side
- Edge
- Remote
- Server-Side
Edge caching involves storing data closer to the end-user, typically on servers at the edge of the network. This reduces latency and improves the user experience.
How does distributed tracing differ from traditional logging and monitoring?
- Distributed tracing focuses on tracking requests as they traverse various services in a microservices architecture, providing end-to-end visibility. Traditional logging captures events and errors but lacks the context of request flow. Monitoring involves tracking system metrics, often lacking detailed request-level insights.
- Distributed tracing is primarily concerned with server-side events, while traditional logging focuses on client-side interactions.
- Distributed tracing is suitable only for monolithic applications, while traditional logging and monitoring are better for microservices.
- Traditional logging and monitoring provide real-time insights, whereas distributed tracing is retrospective in nature.
Distributed tracing is designed to follow the journey of a request across services, offering a comprehensive view of its path. Traditional logging captures events without the contextual flow, and monitoring deals with system-level metrics.
