What is the primary function of Azure Blob Storage?
- Message Queue
- NoSQL Database
- Object Storage
- Relational Database
Azure Blob Storage is an object storage solution in Microsoft Azure. Its primary function is to store and manage unstructured data, such as documents, images, and videos. It provides scalable, secure storage with a simple HTTP/HTTPS interface.
_______ is an architectural style for designing networked applications.
- JSON
- REST
- SOAP
- XML
REST (Representational State Transfer) is an architectural style for designing networked applications. It emphasizes a stateless client-server communication model, scalability, and a uniform interface. RESTful APIs are built based on these principles.
The Strategy design pattern defines a family of _______ algorithms and encapsulates each one, making them interchangeable.
- dependent
- interchangeable
- nested
- related
The Strategy design pattern defines a family of interchangeable algorithms. It allows a client to choose from a family of algorithms and gives them the flexibility to interchange algorithms without altering the client code.
What is the primary purpose of responsive web design?
- To ensure a consistent user experience across various devices and screen sizes
- To focus only on desktop users
- To make web pages load faster
- To use only fixed layouts for web pages
The primary purpose of responsive web design is to ensure a consistent and optimal user experience across various devices and screen sizes. This approach allows websites to adapt to different resolutions and orientations.
_______ is known for its speed and event-driven architecture, making it suitable for building real-time applications and APIs.
- Django
- Flask
- Node.js
- Ruby on Rails
Node.js is known for its speed and event-driven architecture, making it suitable for building real-time applications and APIs. It uses JavaScript on the server side.
The HTML tag is used to represent _______ text.
- Bold
- Highlighted
- Italic
- Underlined
The HTML tag is used to represent bold text. It makes the enclosed text appear bold in the browser.
Your organization has experienced a data breach. Outline the steps you would take to respond and recover from the incident.
- All of the above
- Conduct a forensic investigation
- Identify and contain the breach
- Notify affected parties and regulatory bodies
Responding to a data breach involves a comprehensive approach. Identifying and containing the breach, notifying affected parties, regulatory bodies, and conducting a forensic investigation are critical steps to minimize damage and prevent future incidents.
Explain the difference between query optimization in relational databases and NoSQL databases.
- NoSQL databases do not require query optimization since they are schema-less.
- Optimization in relational databases focuses on SQL queries and involves techniques like indexing and join strategies. NoSQL optimization varies based on the specific database type (e.g., document, key-value, graph), often emphasizing distributed and horizontal scaling.
- Optimization strategies are similar, emphasizing efficient indexing and join operations in both relational and NoSQL databases.
- Query optimization is irrelevant in NoSQL databases as they are designed to handle unstructured data without optimization.
Query optimization in relational databases involves SQL-specific techniques, while NoSQL optimization is context-dependent on the type of NoSQL database used.
You're working on a project that requires real-time data processing. Which cloud platform service would you recommend, and why?
- AWS Lambda
- Azure Stream Analytics
- Google Cloud Dataflow
- IBM Cloud Functions
For real-time data processing, Google Cloud Dataflow is a suitable choice. It allows for both batch and stream processing, making it versatile. It's fully managed, scalable, and integrates seamlessly with other Google Cloud services.
In a project, you need to efficiently find the top 5 most frequent elements in a large dataset. Which data structure and algorithm combination would you use?
- Binary Search Tree (BST)
- Hash Map with Heap
- QuickSort Algorithm
- Trie Data Structure
Using a Hash Map to track element frequencies and a Heap to efficiently find the top elements is a common approach. This combination allows constant-time lookup and log-linear time complexity for maintaining and extracting the most frequent elements.
