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.
In cloud networking, which service allows users to deploy and manage applications without worrying about the underlying infrastructure?
- Infrastructure as a Service (IaaS)
- On-Premises Deployment
- Platform as a Service (PaaS)
- Software as a Service (SaaS)
'Platform as a Service (PaaS)' is a cloud computing service that provides a platform for developers to build, deploy, and manage applications without having to manage the underlying infrastructure. It abstracts hardware and allows a focus on software development.
An organization is assessing its IT risks and identifies a potential threat from an outdated software component. However, the business impact of this threat is deemed to be very low. What might be a suitable course of action?
- Continuously monitor the threat and assess its potential impact.
- Ignore the threat since it has a low business impact.
- Immediately replace the outdated software to eliminate the threat.
- Isolate the outdated software to minimize the risk.
When dealing with a low-impact threat from outdated software, it's typically suitable to continuously monitor the threat and assess its potential impact. This approach allows for a balanced allocation of resources to manage risks effectively.
In the context of cybersecurity, what is the primary goal of data loss prevention (DLP) systems?
- To detect malware
- To encrypt all data
- To prevent all data loss
- To protect against hackers
Data Loss Prevention (DLP) systems are primarily designed to 'protect against hackers' and unauthorized access, ensuring sensitive data doesn't fall into the wrong hands. They use policies and rules to monitor and prevent data breaches.
In agile project management, what term describes a fixed-length iteration during which a potentially shippable product increment is created?
- Kanban
- Scrum
- Sprint
- Waterfall
In agile project management, a 'Sprint' is a fixed-length iteration typically lasting two to four weeks during which the development team creates a potentially shippable product increment. Sprints are a core component of the Scrum framework, an agile methodology.
