You are tasked with securely transmitting credit card data over the internet. Which cryptographic protocol would be most appropriate to ensure data integrity, confidentiality, and authentication?
- FTP
- MD5
- SHA-256
- SSL/TLS
The most appropriate cryptographic protocol for securely transmitting sensitive data like credit card information over the internet is 'SSL/TLS' (Secure Sockets Layer/Transport Layer Security). SSL/TLS provides data integrity, confidentiality, and authentication through encryption and certificates.
You are tasked with setting up a virtual environment where the virtual machines should have direct access to the physical hardware resources without much intervention from the host operating system. Which type of hypervisor would you opt for?
- Full Virtualization
- Paravirtualization
- Type 1 (Bare-Metal Hypervisor)
- Type 2 (Hosted Hypervisor)
In this scenario, a Type 1 hypervisor, also known as a bare-metal hypervisor, is the choice. It allows virtual machines to interact directly with physical hardware, making it a preferred choice for performance-critical environments.
A research team wants to train a model that can generate music based on the style of a given composer. What type of neural network architecture might be most effective for such a task?
- Convolutional Neural Network (CNN)
- Echo State Network (ESN)
- Radial Basis Function Network (RBFN)
- Recurrent Neural Network (RNN)
For generating music based on the style of a composer, a 'Recurrent Neural Network (RNN)' is an effective choice. RNNs are capable of modeling sequential data, making them suitable for tasks that involve capturing patterns and structures in music compositions over time.
The process of identifying and resolving network connectivity issues is known as _______.
- Debugging
- Encryption
- Firewall Configuration
- Troubleshooting
The process of identifying and resolving network connectivity issues is known as 'Troubleshooting.' It involves diagnosing and fixing problems in a network, ensuring that it operates smoothly and efficiently.
An organization detected an unauthorized access attempt from an IP address located in a different country. They want to proactively block future attempts from that entire IP range. Which system would they use to implement this action?
- Firewall
- Intrusion Prevention System (IPS)
- Proxy Server
- Virtual Private Network (VPN)
The organization would use a 'Firewall' to proactively block future access attempts from that entire IP range. Firewalls are network security devices that can filter and control incoming and outgoing traffic based on security policies, including blocking access from specific IP addresses or ranges.
Which type of attack involves overwhelming a network or service with a flood of illegitimate requests to cause it to become unavailable to users?
- Spoofing Attack
- DDoS Attack
- Phishing Attack
- Injection Attack
A "DDoS Attack" (Option b) stands for "Distributed Denial of Service" attack. It involves multiple systems flooding a network or service with a high volume of illegitimate requests, making it unavailable to users. This is a common attack used to disrupt online services.
Which advanced threat detection approach uses machine learning to detect malware content in real time?
- Behavioral Analysis
- Heuristic Analysis
- Sandbox Analysis
- Signature-Based Detection
'Behavioral Analysis' is an advanced threat detection approach that uses machine learning to analyze the behavior of files and processes in real time, identifying abnormal activities and potentially harmful content.
