Cloud Digital Leader Practice Exam 3 — 20 Questions

Question 1

A company runs a customer-facing web application with a published SLA of 99.95% monthly availability. In the past month, the application experienced two outages: a 12-minute outage and a 7-minute outage. Did the company meet its SLA?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

Yes — 99.95% availability in a 30-day month allows approximately 21.6 minutes of downtime; total outage of 19 minutes is within the budget, meaning the SLA was met. The SLA of 99.95% monthly availability permits a maximum downtime of approximately 21.6 minutes in a 30-day month (total minutes in month × (1 - 0.9995) = 43,200 × 0.0005 = 21.6 minutes). The combined outage of 19 minutes (12 + 7) is within this budget, so the SLA was met. This calculation assumes a 30-day month; if the month had 31 days, the allowable downtime would be about 22.3 minutes, still exceeding 19 minutes.

Answer

No — the company missed the SLA because any outage automatically constitutes an SLA breach

Answer

The answer cannot be determined without knowing the cause of the outages

Answer

No — two separate outages in one month always constitute an SLA breach regardless of duration

Question 2

A multinational retail company has an on-premises infrastructure with a mix of Windows and Linux servers. They are planning to migrate their e-commerce platform to Google Cloud to take advantage of scalability and reduce latency. The platform consists of a web frontend (Apache), a backend API (Node.js), and a MySQL database. They want to minimize downtime during the migration. They have a limited budget and need a solution that is cost-effective and quick to implement. The IT team has experience with containers but prefers to avoid managing Kubernetes. Which approach should they take?

Accepted Answer

Migrate the frontend to App Engine Standard, the backend to Cloud Run, and the database to Cloud SQL with read replicas.. It combines fully managed, serverless services (App Engine Standard for the web frontend and Cloud Run for the backend API) with Cloud SQL for the database, which meets the requirements of minimizing downtime, being cost-effective, and avoiding Kubernetes management. App Engine Standard and Cloud Run automatically scale to zero when not in use, reducing costs, and Cloud SQL with read replicas provides high availability and low-latency reads without complex orchestration. This approach also allows for a gradual migration with minimal disruption, as the existing code can be adapted with minimal changes.

Answer

Use Compute Engine for the web frontend, Cloud Functions for the backend API, and Cloud Spanner for the database.

Answer

Lift and shift all components to Compute Engine with an autoscaling managed instance group, and migrate the database to Cloud SQL.

Answer

Containerize all components using GKE, use Cloud SQL for the database, and deploy using a CI/CD pipeline.

Question 3

A company wants to allow a third-party security firm to conduct a penetration test against their Google Cloud environment to identify vulnerabilities. What is Google Cloud's policy on penetration testing?

Accepted Answer

Customers are authorized to penetration test their own GCP resources without prior Google approval, within the Acceptable Use Policy.. Google Cloud's policy explicitly authorizes customers to conduct penetration testing on their own GCP resources without prior approval from Google, as long as the testing complies with the Acceptable Use Policy. This is because Google treats the customer's environment as their own responsibility, and the shared responsibility model places security testing under the customer's control. Option B correctly reflects this policy, which is documented in Google Cloud's security testing guidelines.

Answer

Customers must submit a formal request to Google and wait for written approval before any penetration testing.

Answer

Penetration testing is illegal in cloud environments and customers should use vulnerability scanners instead.

Answer

Google automatically performs penetration testing on all customer resources monthly and shares the report.

Question 4

An architect is evaluating trade-offs between using Google Cloud's global network backbone for application traffic versus routing traffic over the public internet. She notes that Google's global network is one of the largest private networks in the world. What is the primary performance advantage of routing application traffic over Google's private backbone?

Accepted Answer

Traffic on Google's private backbone avoids public internet congestion and variable routing, providing consistently lower latency and higher throughput for traffic between regions and to users near Google PoPs. Google's private backbone is a dedicated, software-defined network that uses Google's own fiber infrastructure and BGP routing policies to keep traffic entirely within Google's controlled environment. This avoids the unpredictable congestion, packet loss, and variable routing paths of the public internet, resulting in consistently lower latency and higher throughput for traffic between Google Cloud regions and to users near Google Points of Presence (PoPs).

Answer

Google's private backbone uses faster optical fiber than public internet service providers

Answer

Google's private backbone is free for customers while public internet egress incurs data transfer charges

Answer

Using Google's backbone eliminates the need for application-level TLS encryption because the network is inherently secure

Question 6

A company's finance team wants to understand why their cloud bills vary significantly month to month, unlike their fixed on-premises IT costs. Which fundamental cloud pricing characteristic explains this variability?

Accepted Answer

Consumption-based pricing means cloud costs scale directly with actual usage, unlike fixed on-premises costs. Cloud computing operates on a consumption-based (pay-as-you-go) pricing model, where costs are directly tied to the amount of resources consumed (e.g., compute hours, storage GB, data transfer). Unlike fixed on-premises IT costs, which are incurred regardless of actual usage (e.g., hardware depreciation, facility leases), cloud bills fluctuate as usage scales up or down. This fundamental characteristic explains the month-to-month variability observed by the finance team.

Answer

Cloud providers change their prices frequently, causing unpredictable costs

Answer

Cloud providers apply hidden fees that vary randomly each month

Answer

Cloud costs are fixed like on-premises costs; the variability must be caused by billing errors

A company's security team wants to control which resources on the internet can communicate with their virtual machines in Google Cloud. Which fundamental cloud networking concept provides this control?

Accepted Answer

VPC firewall rules that control inbound and outbound network traffic to VMs based on IP ranges, protocols, and ports. VPC firewall rules are the fundamental cloud networking construct that controls network traffic to and from virtual machine instances in Google Cloud. These rules operate at the network layer, filtering traffic based on source/destination IP ranges, protocols (e.g., TCP, UDP, ICMP), and port numbers, thereby governing which internet resources can communicate with the VMs.

Answer

Cloud IAM policies that grant or deny permissions for external systems to access VM resources

Answer

Cloud Storage bucket policies that restrict access to VM storage volumes

Answer

DNS records that determine which internet addresses can resolve the VM's hostname

Question 15

A company wants to send transactional emails (receipts, password resets) and marketing emails at scale from their application. Which approach is recommended when using Google Cloud?

Accepted Answer

Integrate a third-party email delivery service (e.g., SendGrid, Mailgun) with the GCP application.. Google Cloud does not provide a native transactional email service, so integrating a dedicated third-party email delivery service like SendGrid or Mailgun is the recommended approach. These services handle deliverability, reputation management, and compliance with email standards (e.g., SPF, DKIM, DMARC), which are critical for high-volume transactional and marketing emails. Using GCP's native services like Cloud Functions or App Engine to send emails directly would rely on SMTP relays that often have strict sending limits and poor deliverability.

Answer

Use Gmail to manually send all transactional emails.

Answer

Use BigQuery to store and send emails directly to customers.

Answer

Deploy an SMTP server on Compute Engine and send emails directly from GCP IP addresses.

Question 16

A company's risk management team wants to understand Google Cloud's approach to supply chain security — specifically, how Google ensures that the hardware and firmware running in its data centers have not been tampered with. Which Google security initiative addresses hardware supply chain integrity?

Answer

Google relies on hardware manufacturers' security certifications to ensure supply chain integrity

Answer

Google encrypts all hardware components with AES-256 to prevent tampering

Question 17

A business user asks what makes cloud storage different from simply buying a larger external hard drive for the office. Which characteristic most clearly differentiates cloud storage from local storage devices?

Accepted Answer

Cloud storage is accessible from anywhere via the internet, scales elastically without hardware purchases, and provides built-in redundancy across multiple physical locations. Cloud storage is fundamentally different from local storage because it provides internet-based accessibility, elastic scalability without requiring hardware procurement, and built-in redundancy across geographically distributed data centers. These characteristics enable on-demand resource provisioning and high availability, which a single external hard drive cannot offer. The correct answer, B, captures these core differentiators that align with the NIST definition of cloud computing.

Answer

Cloud storage is faster than local storage for all types of data access

Answer

Cloud storage cannot be used for backup, while external hard drives are purpose-built for backup

Answer

Cloud storage requires specialized hardware on the customer's side to access data

Question 18

A company exports all their Google Cloud logs to Cloud Storage for long-term retention required by their compliance policy (7-year log retention). Which Cloud Logging feature enables routing logs to Cloud Storage?

Accepted Answer

Configure a Cloud Logging sink (log router) that routes logs to a Cloud Storage bucket.. Cloud Logging uses sinks (log routers) to export logs to supported destinations, including Cloud Storage. A sink defines a filter and a destination; when configured, it routes matching log entries to the specified Cloud Storage bucket for long-term retention. This is the only native mechanism for continuous, automated log export without custom scripting.

Answer

Cloud Logging automatically archives all logs to Cloud Storage with no configuration needed.

Answer

Enable log streaming in Cloud Storage settings to receive logs from Cloud Logging.

Answer

Use the Cloud Logging API to periodically download logs and upload them to Cloud Storage.

Question 19

A product manager wants to understand what 'latency' means for her company's cloud-hosted e-commerce application. Her developer explains that latency is critical for user experience. Which definition of latency is most accurate in this context?

Accepted Answer

Latency is the time elapsed between a user action (click, page load) and receiving the server's response — directly affecting how fast and responsive the application feels. Latency in the context of a cloud-hosted e-commerce application specifically measures the round-trip time from a user action (such as a click or page load) to the receipt of the server's response. This directly impacts perceived responsiveness and user experience, as higher latency leads to noticeable delays in interactions like adding items to a cart or checking out.

Answer

Latency is the total amount of data that can be transferred per second between the user and the application

Answer

Latency is the percentage of time the application is available versus unavailable

Answer

Latency is the number of requests the server can handle simultaneously before performance degrades

Question 20

A cloud team wants to understand their current Google Cloud resource inventory — specifically, which VMs are running in each region, their machine types, and whether they have public IP addresses. Which approach most efficiently provides this across all projects?

Accepted Answer

Use Cloud Asset Inventory to run a single org-wide query that returns all VM instances, their regions, machine types, and network configurations across all projects. Cloud Asset Inventory provides a single, unified API to query resources across all projects in an organization. By using the `gcloud asset search-all-resources` command with the `--asset-types=compute.googleapis.com/Instance` filter, you can retrieve all VM instances along with their regions, machine types, and network configurations (including public IP addresses) in one operation, without needing to access each project individually.

Answer

Log into each Google Cloud project individually through the Console and manually record VM details in a spreadsheet

Answer

Check the Cloud Billing reports, which list all resources that have incurred charges by resource type

Answer

Enable VPC flow logs in each project to capture VM network activity
