What is the difference between structured and unstructured logging?
- Structured logging is only suitable for large-scale applications, while unstructured logging is more flexible for small projects.
- Structured logging is suitable for backend systems, while unstructured logging is preferred for frontend development.
- Structured logging provides well-defined formats for log entries, making them machine-readable and easily searchable. Unstructured logging, on the other hand, lacks a predefined format, making it harder to analyze automatically.
- Structured logging uses a hierarchical format, while unstructured logging uses a flat format.
Structured logging introduces a consistent format to log entries, aiding in automated analysis and troubleshooting. Unstructured logging, by contrast, lacks a standardized format, making it less suitable for automated processing.
Which server-side language is known for its simplicity and readability, often used for web development alongside frameworks like Django and Flask?
- Java
- PHP
- Python
- Ruby
Python is known for its simplicity and readability, making it a popular choice for server-side web development. It is often used with frameworks like Django and Flask.
RESTful APIs follow the principle of _______ over configuration.
- Configuration
- Convention
- Simplicity
- Standardization
RESTful APIs follow the principle of Convention over Configuration (CoC). This means that developers only need to specify unconventional aspects of the application. Conventions are predefined rules that simplify development and promote consistency.
What is the purpose of continuous integration in the context of pull requests and code review?
- Automatically Integrates Code Changes
- Enhances Collaboration Among Developers
- Ensures Code Quality through Automated Builds
- Identifies and Fixes Bugs Early
Continuous Integration ensures code quality by automatically building and testing changes as soon as they are pushed. This helps catch and fix issues early, promoting collaboration and maintaining a reliable codebase.
In a project with a strict release schedule, a merge conflict arises just before a critical deadline. How would you prioritize resolving the conflict while minimizing disruption to the release timeline?
- Delegate the conflict resolution to another team member.
- Identify critical changes for the release, prioritize resolving conflicts related to those changes first, and communicate with the team about any potential delays.
- Ignore the conflict until after the release, focusing on meeting the deadline.
- Roll back all changes, releasing the previous version without the conflicting updates.
Prioritizing conflicts based on critical changes ensures that essential features are not compromised. Effective communication is crucial to manage expectations regarding potential delays.
In database design, a _______ is a collection of database objects, such as tables, views, and indexes.
- Cluster
- Index
- Schema
- Tablespace
In database design, a schema is a collection of database objects, such as tables, views, and indexes. It provides a logical structure for organizing and accessing data in a database.
The "git merge --no-ff" command ensures a _______ merge.
- Non-Fast-Forward
- Force
- Recursive
- Annotated
The "git merge --no-ff" command ensures a Non-Fast-Forward merge. This option preserves the branch hierarchy, creating a new merge commit even if it could be fast-forwarded. It provides a cleaner history and better traceability.
Query optimization techniques can vary significantly depending on the _______ model used by the database system.
- Concurrency
- Data
- Query language
- Storage
Query optimization techniques can vary significantly depending on the query language model used by the database system. Different query languages may have distinct optimization strategies, affecting the overall performance of queries.
_______ allows developers to create and maintain documentation for their projects, making it easier for team members to understand the codebase.
- Code Linting
- Continuous Integration (CI)
- Documentation Generator
- Version Control System (VCS)
Documentation Generator allows developers to create and maintain documentation for their projects, making it easier for team members to understand the codebase. Clear documentation is crucial for code maintainability and knowledge transfer.
