Which virtualization type abstracts and isolates workloads from the physical host machine, allowing for portability, flexibility, and scalability?
- Container Virtualization
- Network Virtualization
- Server Virtualization
- Virtual Machine (VM) Virtualization
Virtual Machine (VM) Virtualization abstracts entire VMs from the host, enabling portability and flexibility as VMs can run on different hosts without modification.
Under the GDPR, what rights does an individual have concerning automated decision-making and profiling?
- The right to access results
- The right to data portability
- The right to opt-out
- The right to refuse consent
Under GDPR, individuals have the right to opt-out of automated decision-making and profiling that significantly affects them.
One of the primary reasons for data breaches in an organization is due to ________.
- External Hackers
- Inadequate Encryption
- Insider Threats
- Lack of Firewalls
Insider threats are a significant cause of data breaches, as employees or insiders have access to sensitive data and may misuse it intentionally or unintentionally.
An e-commerce platform is experiencing challenges in managing user sessions across its distributed infrastructure. They are considering a middleware solution to manage and maintain user session data uniformly. What kind of middleware should they look into?
- Distributed Cache
- Message Queues
- Publish-Subscribe
- Remote Procedure Calls
A Distributed Cache can efficiently manage and maintain user session data across a distributed infrastructure, ensuring uniform access and reliability.
Which technology enables devices to gather and exchange data over the internet, which can then be processed and analyzed in the cloud?
- 5G
- LoRa
- MQTT
- Wi-Fi
MQTT (Message Queuing Telemetry Transport) is a lightweight messaging protocol that enables devices to gather and exchange data over the internet. This data can be transmitted to the cloud for processing and analysis. MQTT is commonly used in IoT applications.
Virtualization technology allows multiple ________ to run on a single physical machine.
- Applications
- Operating Systems
- Processors
- Virtual Machines
Virtualization technology enables multiple virtual machines (VMs) to run on a single physical machine, abstracting and isolating each VM from the host hardware. This enables efficient resource utilization and isolation.
In Kubernetes, what is the role of an "etcd"?
- A container orchestration tool
- A container runtime
- A distributed file system for pod data
- A network overlay solution
Etcd is a distributed key-value store used in Kubernetes to store all configuration data, which ensures high availability and consistency. It's crucial for maintaining a shared configuration and service discovery among all nodes in the cluster.
Which of the following is a form of virtualization that separates a physical machine into multiple virtual machines?
- Hypervisor
- Emulation
- Containerization
- Virtual Private Network (VPN)
The correct option is 'Hypervisor.' A hypervisor is a type of virtualization technology that allows a single physical machine to run multiple virtual machines. These virtual machines, or VMs, are isolated from each other and from the host system. The hypervisor controls and allocates hardware resources to these VMs, making it an efficient solution for server virtualization. Virtual Private Networks (VPNs) are not related to machine virtualization. Emulation often replicates a specific environment for compatibility, while containerization is a different virtualization method where applications share the same OS kernel.
A software company in the EU offers a service that uses machine learning to make automated decisions about user profiles. A user is unhappy about a decision made about him and requests an explanation. Under which regulation and provision should the company address this request?
- CCPA, Section 1798.105
- GDPR, Article 22
- HIPAA, Section 164.524
- ISO 27001, Clause 8.2.3
GDPR, Article 22, grants users the right to request an explanation for automated decisions that significantly affect them. This ensures transparency and accountability in cases where algorithms or AI systems are used for decision-making.
While the ________ strategy offers a faster migration, it may not immediately take full advantage of cloud-native capabilities.
- Refactoring
- Rehosting
- Replatforming
- Repurchasing
The blank should be filled with "Rehosting." Rehosting is a migration strategy where applications are moved to the cloud with minimal changes, offering a faster migration but not leveraging cloud-native capabilities.
