CS Cloud Computing & Services 5

Question 1

Which system is the de facto standard for orchestrating containers across a cluster, handling scheduling, scaling, and self-healing?

Accepted Answer

Kubernetes

Answer

Kubernetes automates deployment, scaling, and management of containerized applications across clusters.

Question 2

Processing data near where it is generated, such as on IoT devices, instead of sending everything to a central cloud is called what?

Accepted Answer

Edge computing

Answer

Edge computing moves computation closer to data sources to reduce latency and bandwidth usage.

Question 3

A team migrates an application to the cloud by moving VMs as-is, without redesigning the application. What is this migration strategy called?

Accepted Answer

Lift and shift (rehosting)

Answer

Lift and shift moves workloads to the cloud unchanged, trading cloud-native benefits for migration speed.

Question 4

What is a common cause of unexpected latency in a serverless function that has not been invoked recently?

Accepted Answer

Cold start, where the runtime environment must be initialized

Answer

A cold start occurs when the provider must provision and initialize a new execution environment before running the function.

Question 5

Which practice helps prevent a single misconfigured cloud storage bucket from exposing sensitive data publicly?

Accepted Answer

Enforcing least-privilege access policies and blocking public access by default

Answer

Least-privilege policies and default public-access blocks are the primary defenses against accidental bucket exposure.
