Cloud Digital Leader Why Cloud Technology Can Transform Business Practice Test 2 — 15 Questions

Question 1

A startup wants to launch a new application quickly and only pay for the compute resources they use, avoiding upfront hardware purchases. Which cloud benefit best supports this goal?

Accepted Answer

Cost optimisation (pay-as-you-go). Pay-as-you-go pricing allows customers to pay only for what they use, avoiding large capital expenditures (CAPEX) on hardware. Agility is about speed, scalability is about handling load, and global reach is about geographic coverage.

Answer

Scalability

Answer

Agility

Answer

Global reach

Question 2

A company runs a batch job that processes data every night. The job can tolerate interruptions and currently runs on a dedicated on-premises server that is underutilized. They want to migrate to Google Cloud and minimise compute cost. Which compute option is most cost-effective?

Accepted Answer

Preemptible VMs. Preemptible VMs offer significantly lower cost (up to 80% discount) but can be terminated at any time, making them ideal for fault-tolerant batch workloads. Standard VMs are more expensive, sole-tenant nodes are for isolation, and GPUs add cost.

Answer

Sole-tenant nodes

Answer

Standard (on-demand) VMs

Answer

VMs with GPUs

Question 3

A retail company experiences sudden traffic spikes during flash sales. Their on-premises infrastructure often runs out of capacity, causing downtime. They are migrating to Google Cloud and need to automatically handle traffic spikes without manual intervention. Which approach should they take?

Accepted Answer

Create a managed instance group with autoscaling. Managed instance groups with autoscaling automatically add and remove VM instances based on load, handling spikes without manual intervention. GPUs are not needed; manual scaling is wasteful; Cloud Load Balancing alone does not auto-scale compute.

Answer

Manually add VMs when traffic increases

Answer

Use a GPU-accelerated VM for compute

Answer

Use a single large VM and rely on Cloud Load Balancing

Question 4

A company wants to reduce its carbon footprint and has committed to using 100% renewable energy for its cloud infrastructure. Which Google Cloud value proposition directly supports this goal?

Accepted Answer

Answer

Open cloud (Kubernetes/TensorFlow)

Answer

Security (BeyondCorp/encryption)

Answer

Trust and compliance (certifications)

Question 5

A financial services firm must keep sensitive data on-premises due to regulatory requirements but wants to use Google Cloud's AI/ML services for analytics on that data. Which deployment model should they adopt?

Accepted Answer

Hybrid cloud (on-premises + Google Cloud). Hybrid cloud connects on-premises infrastructure to Google Cloud, allowing data to remain on-prem while leveraging cloud AI/ML services via secure connections. Public cloud would move data off-prem, private cloud is on-prem only, multi-cloud is about multiple public clouds.

Answer

Scalability

Answer

Agility

Answer

Innovation (AI/ML access)

Question 7
