Which of the following best describes the term "risk appetite" in IT risk management?
- A measure of potential profit
- A tolerance for loss
- Likelihood of an incident
- Willingness to accept risk
"Risk appetite" in IT risk management refers to an organization's 'willingness to accept risk.' It signifies how much risk an organization is prepared to undertake in pursuit of its objectives, balancing potential rewards and uncertainties.
Which layer of the OSI model deals with the logical addressing of devices and routing?
- Data link layer
- Network layer
- Physical layer
- Transport layer
The 'Network layer' in the OSI model is responsible for logical addressing of devices and routing. This layer handles tasks like IP addressing and determining the best path for data to travel.
Which type of database is designed to store data in key-value pairs?
- Columnar Database
- Graph Database
- NoSQL Database
- Relational Database
NoSQL databases are designed to store data in various formats, including key-value pairs. They are suitable for handling unstructured or semi-structured data and are often used in modern web and big data applications.
Web pages that can change content dynamically without requiring the page to be fully reloaded are often referred to as _______.
- AJAX pages
- Cookies
- Dynamic pages
- Static pages
Web pages that can change content dynamically without a full page reload are often referred to as 'AJAX pages.' AJAX stands for Asynchronous JavaScript and XML, and it allows for seamless, dynamic content updates in web applications.
In a hybrid cloud environment, what mechanism ensures secure data transmission between on-premises data centers and the cloud?
- Cloud-based firewall
- Data encryption
- Intrusion Detection System (IDS)
- Virtual Private Network (VPN)
In a hybrid cloud environment, a 'Virtual Private Network (VPN)' is commonly used to ensure secure data transmission between on-premises data centers and the cloud. VPNs create encrypted communication tunnels over the public internet, enhancing security. Data encryption alone may not secure the entire transmission path.
The technology that enables one physical piece of hardware to function as multiple "logical" devices is known as _______.
- Cloud Computing
- Firewall
- Mainframe
- Virtualization
The technology that enables one physical piece of hardware to function as multiple "logical" devices is called 'Virtualization.' It abstracts and isolates resources for efficient use.
A security measure where multiple layers of defense are placed throughout an information technology system is known as _______.
- Antivirus
- Defense-in-Depth
- Encryption
- Firewall
Defense-in-Depth is a comprehensive security strategy that involves implementing multiple layers of defense mechanisms to protect an IT system, making it more resilient to various threats and attacks.
Which type of virtualization allows multiple operating systems to run on a single physical machine?
- Application Virtualization
- Cloud Virtualization
- Hypervisor Virtualization
- Network Virtualization
Hypervisor virtualization allows multiple operating systems (OS) to run on a single physical machine simultaneously. A hypervisor, also known as a virtual machine monitor, manages and allocates resources to each virtualized OS, enabling efficient utilization of hardware resources and facilitating tasks like testing different OS environments on a single server.
In computer architecture, what is the role of the control unit?
- Executes arithmetic operations
- Manages computer peripherals
- Manages instruction execution
- Stores data temporarily
In computer architecture, the 'control unit' is responsible for managing instruction execution. It fetches, decodes, and coordinates the execution of instructions, ensuring the proper flow of data and control within the CPU.
In the realm of information assurance, which process ensures that data has not been altered during transmission?
- Data Authentication
- Data Compression
- Data Encryption
- Data Integrity Check
Data Integrity Check ensures that data remains unaltered during transmission. This is typically achieved through methods like checksums or hash functions, which detect any changes in data.
