Question 8

A company runs a batch processing workload every night that takes 60 minutes on a single n1-standard-32 VM. They want to reduce costs by using preemptible VMs but need the job to complete within 90 minutes. The job can be parallelized if necessary. Which approach is most cost-effective?

Accepted Answer

Split the workload across 4 preemptible n1-standard-8 VMs with checkpointing.. Preemptible VMs can be terminated at any time, so running multiple smaller instances with checkpointing and retries reduces cost and meets the deadline.

Answer

Use a single non-preemptible VM to ensure completion.

Answer

Use the same VM but as preemptible; if preempted, restart the job from scratch.

Answer

Use a single preemptible VM with persistent disk snapshots every 10 minutes.

Question 9

A data analytics firm wants to query data across Cloud Storage and BigQuery without moving the data. They need a single SQL interface. Which Google Cloud service enables this?

Accepted Answer

BigQuery external tables (federated queries). BigQuery allows querying external data sources like Cloud Storage via external tables (federated queries) without loading data.

Answer

Answer

Cloud SQL federated queries

Answer

BigQuery Omni

Question 10

A company wants to reduce its carbon footprint by using cloud infrastructure powered by renewable energy. Which Google Cloud sustainability commitment is most relevant?

Accepted Answer

100% renewable energy match. Google Cloud matches 100% of its global electricity consumption with renewable energy purchases.

Answer

Net zero emissions by 2025

Answer

Carbon offset program

Answer

Carbon-free energy by 2025

Question 11

A company is evaluating total cost of ownership (TCO) for migrating a legacy application to Google Cloud. Which cost should they include in the cloud TCO calculation that is often overlooked?

Accepted Answer

Data egress fees. Egress charges for data leaving Google Cloud are an often-overlooked cost that can significantly impact TCO.

Answer

Software licensing for operating systems

Answer

Cost of physical security for data centers

Answer

Cost of electricity for servers

Question 12

A customer wants to run a containerized application on Google Cloud with zero downtime during updates and the ability to roll back quickly. Which service and deployment strategy should they use?

Accepted Answer

Google Kubernetes Engine with rolling updates. Google Kubernetes Engine (GKE) with a rolling update strategy provides zero-downtime deployments and easy rollback via kubectl rollout undo.

Answer

Compute Engine with a load balancer and instance group update

Answer

Cloud Run with manual traffic splitting

Answer

App Engine with automatic scaling

Question 13

A company wants to store data across multiple regions for disaster recovery and comply with data residency requirements in the European Union. Which TWO Google Cloud features should they use?

Accepted Answer

Cloud Storage Object holds. Dual-region buckets store data in two regions within a continent, meeting data residency. Object holds prevent premature deletion during replication. Multi-region is not recommended for data residency because it may spread data globally.

Answer

Cloud CDN

Answer

Cloud Interconnect

Answer

Multi-region Cloud Storage buckets

Question 14

A financial company wants to run sensitive workloads on Google Cloud while ensuring data never leaves a specific geographic boundary and meets strict compliance requirements. Which THREE Google Cloud services should they combine?

Question 15

A retail company runs a web application on Google Kubernetes Engine (GKE). They want to automatically scale the application based on custom metrics (e.g., number of items in a shopping cart). Which TWO resources should they configure?

Accepted Answer

Custom Metrics Stackdriver Adapter. Horizontal Pod Autoscaler (HPA) can scale pods based on custom metrics. Custom Metrics adapter (e.g., Stackdriver adapter) exposes application metrics to HPA.

Answer

Cluster Autoscaler

Answer

Vertical Pod Autoscaler (VPA)

Answer

Cloud Load Balancing

Question 16

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 17

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 18

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 19

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

Sustainability (renewable energy match). Google Cloud matches 100% of its global energy consumption with renewable energy and aims for carbon-free energy by 2030. Security, open source, and compliance are unrelated to renewable energy.

Answer

Open cloud (Kubernetes/TensorFlow)

Answer

Security (BeyondCorp/encryption)

Answer

Trust and compliance (certifications)

Question 20

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

Private cloud (on-premises only)

Answer

Multi-cloud (AWS + Azure + Google Cloud)

Answer

Public cloud (Google Cloud only)
