Which cryptographic algorithm uses two keys: one public and one private?
- AES
- DES
- RSA
- SHA
The RSA algorithm uses a pair of keys - one public and one private. The public key is used for encryption, while the private key is used for decryption. It's widely used for secure data transmission and digital signatures.
Malware that is designed to replicate itself and spread to other devices or systems is known as _______.
- Spyware
- Trojan Horse
- Virus

When an operating system spends much of its time paging, rather than executing application software, it is said to be in a state of _______.
- Booting
- Fragmentation
- Multitasking
- Thrashing
'Thrashing' occurs in an operating system when it spends a significant amount of time swapping data between RAM and secondary storage due to excessive paging. This can severely degrade system performance and is an undesirable state.
What is the primary purpose of recurrent neural networks (RNNs)?
- Dimensionality reduction
- Handling static data
- Image classification
- Modeling sequential data
RNNs are designed for 'modeling sequential data.' They are capable of processing data with temporal dependencies, making them suitable for tasks like natural language processing, speech recognition, and time series analysis. RNNs maintain a hidden state that carries information from previous time steps.
You are tasked with creating a web application that will have high traffic with users all around the world. Which deployment approach might help distribute the load and deliver content faster to users?
- Agile Development
- Database Normalization
- Multi-Region Deployment
- Waterfall Model
Multi-Region Deployment involves deploying your application in multiple geographic regions. This approach helps distribute the load and deliver content faster to users by serving content from servers closer to the end-users, reducing latency and improving performance.
When automating a web application test that requires multiple browser interactions, which Python framework provides robust solutions?
- Behave with Appium
- PyTest with Splinter
- Robot Framework with WebDriver
- Selenium with Python
Selenium with Python is a powerful combination for automating web applications that require multiple browser interactions. Selenium provides a robust set of tools and libraries for browser automation, and when combined with Python, it offers a flexible and scalable solution for writing and executing web tests. PyTest, Behave, and Robot Framework are also popular testing frameworks but may not be as specialized for multi-browser interactions as Selenium with Python.
