Architecture & Infrastructure Concepts Flashcards
Which are common examples of SCADA systems?
A. KVM datacenter systems
B. Power Grid
C. Fire detection and suppression
D. Water management
E. Facility and manufacturing control
F. Traffic and mass transit
B. Power Grid
D. Water management

Which type of hypervisor is also referred to as “native” or “bare metal”?
A. Type III
B. Type IV
C. Type I
D. Type II
C. Type I
Which term describes the provisioning and operations of infrastructure using configuration files that contain the infrastructure specifications instead of by manual processes?
A. Platform-as-a-service
B. Infrastructure-as-code
C. Hybrid cloud deployment
D. Managed security service provision
B. Infrastructure-as-code
Infrastructure-as-code (IaC) is a practice that uses code (configuration files) to manage and provision infrastructure. This approach automates the process, making it more efficient, reliable, and less prone to human error.
Which are valid examples of serverless technologies? Choose more than one option.
A. Functions
B. Controllers
C. Containers
D. Bastion hosts
E. Databases
F. Switches
A. Functions
C. Containers
D. Bastion hosts
E. Databases
In which type of network system does each node make its own decision and the final behavior of the system is the aggregate of the decisions of each individual node or host?
A. Centralized design
B. Software defined design
C. Decentralized design
D. Air gapped design
C. Decentralized design
In a decentralized network, each node operates independently, making its own decisions based on local information and rules.
Examples of decentralized networks include blockchain networks and peer-to-peer file-sharing networks.
In the cloud computing shred responsibility model (SRM) which service type does the provider bear the LEAST responsibility?
A. DBaaS
B. SaaS
C. PaaS
D. IaaS
D. IaaS
With IaaS, the provider is primarily responsible for the physical infrastructure, such as servers, storage, and networking. The customer, however, is responsible for managing the operating systems, applications, and data on those resources.
Which acronym refers to the collective network of connected devices and the technology that facilitates communication between devices and the cloud, as well as between the devices themselves?
A. IaaS
B. IaC
C. IoT
D. SaaS
C. IoT
Which is a framework intended to make a network more flexible and easier to centrally manage by abstracting the control plane from the data forwarding function in the different networking devices?
A. AWS
B. SDN
C. GCP
D. CSP
B. SDN
SDN (Software-Defined Networking) is a network architecture that separates the control plane from the data plane. This separation allows for centralized management and control of network functions, making the network more flexible, programmable, and easier to manage.
Which metric specifically refers to long-term data protection where the stored data does not suffer from bit rot, degradation, or other corruption?
A. Durability
B. Availability
C. Capacity
D. Resiliency
A. Durability
Durability refers to the ability of a storage system to maintain data integrity over an extended period, ensuring it is not susceptible to bit rot, degradation, or other forms of corruption.
What is a discrete environment within an operating system (or a serverless architecture) where one or more applications can run that is typically assigned all the resources and dependencies needed to function?
A. Containers
B. Functions
C. Partitions
D. Controllers
A. Containers
Containers provide a self-contained environment for applications, including their dependencies, libraries, and configurations. This isolation ensures that applications run consistently across different environments, whether it’s on a developer’s machine, a test server, or a production environment.
