⫸ Additive manufacturing. Ans: Process of creating objects by
adding layers of material
⫸ Filament printing. Ans: Type of 3D printing that uses melted
filament to create objects layer by layer
⫸ Fused deposition modeling (FDM). Ans: Another term for
filament printing
⫸ Print bed. Ans: Surface used for 3D printing, can be adhesive on
top or bottom
⫸ Resin printing. Ans: Type of 3D printing that uses liquid resin and
a light source to create objects layer by layer
⫸ Stereolithography printer. Ans: Another term for resin printing
⫸ Private cloud. Ans: Cloud infrastructure owned and used
exclusively by a single organization
,⫸ Public cloud. Ans: Cloud infrastructure provided by a third party
and accessible to anyone
⫸ Hybrid cloud. Ans: Combination of private and public cloud
deployments
⫸ Infrastructure as a Service (IaaS). Ans: Cloud deployment model
where the cloud provider manages the hardware and the end user
manages the rest
⫸ Software as a Service (SaaS). Ans: Cloud deployment model
where the cloud provider manages the entire application and the end
user simply uses it
⫸ Platform as a Service (PaaS). Ans: Cloud deployment model
where the cloud provider provides a platform for the end user to build
and deploy their own applications
⫸ Virtualization. Ans: Technology that allows multiple operating
systems to run on one physical device
⫸ Hypervisor. Ans: Software that manages virtual machines and
their resources
⫸ VM escape. Ans: Security vulnerability where malware on a
virtual machine gains access to the hypervisor and other virtual
machines
,⫸ Sandboxing. Ans: Isolating software development and testing
environments to prevent interference with production systems
⫸ Troubleshooting. Ans: Process of identifying and resolving
problems in a system or application
⫸ Change control. Ans: Formal process for implementing changes in
a controlled and documented manner
⫸ Root cause. Ans: Underlying reason for a problem or issue
⫸ Plan of action. Ans: Detailed plan for implementing a fix or
resolution to a problem
⫸ Rollback. Ans: Reverting back to a previous configuration or state
⫸ Preventative measures. Ans: Actions taken to prevent a problem
from occurring in the future
⫸ Lab testing. Ans: Testing a fix or solution in a controlled
environment before implementing it in the production environment
⫸ Change control board. Ans: Group responsible for reviewing and
approving changes to the environment
, ⫸ Network Cables. Ans: Cabling used for network communication,
such as twisted pair and coaxial cables.
⫸ Twisted Pair. Ans: Type of copper cabling commonly used for
ethernet networks, with four pairs of wires twisted together to reduce
interference.
⫸ Category 5e. Ans: Enhanced version of category 5 twisted pair
cable, commonly used for ethernet networks with a maximum
distance of 100 meters.
⫸ Category 6A. Ans: Augmented version of category 6 twisted pair
cable, supported by 10GBASE-T ethernet standard for a maximum
distance of 100 meters.
⫸ Coaxial Cable. Ans: Cable with a central wire conductor,
insulator, metal shielding, and plastic jacket, commonly used for cable
modem networks.
⫸ Plenum-rated Cable. Ans: Special type of network cable used in
shared plenum areas to prevent smoke or toxic fumes during a fire,
with FEP or low smoke PVC jacket.
⫸ UTP. Ans: Unshielded Twisted Pair cable, commonly used for
ethernet networks with no special shielding around the cables or
individual wires.
