Cloud Armor can apply security policies and help filter malicious or unwanted traffic before it reaches protected backend resources. BigQuery is designed for analytics, Cloud SQL provides managed relational databases, and Cloud Scheduler executes scheduled tasks. Therefore, when an organization needs protection against volumetric and application-layer attacks for internet-facing services, Cloud Armor and Google’s associated DDoS protection capabilities are the appropriate choice.

Q205. Which Google Cloud service should be used to store API keys, passwords, and other application secrets securely?

1) Cloud Storage
2) Secret Manager
3) Cloud DNS
4) Cloud Monitoring

Correct Answer: 2)

Explanation:

Secret Manager is designed specifically for securely storing, managing, and accessing sensitive information such as API keys, passwords, certificates, and tokens. Applications can retrieve secrets at runtime through authenticated access instead of embedding credentials directly into source code or configuration files. Secret Manager also supports secret versions, allowing organizations to manage updates and rotations more effectively. Cloud Storage is intended for object storage, Cloud DNS manages domain resolution, and Cloud Monitoring collects metrics and supports alerting. Therefore, when an application needs a secure centralized location for credentials and other sensitive values, Secret Manager is the most appropriate Google Cloud service.

Q206. Which Google Cloud service allows organizations to define and enforce constraints on resource configurations?

1) Organization Policy Service
2) Cloud Profiler
3) Cloud Trace
4) Cloud Scheduler

Correct Answer: 1)

Explanation:

Organization Policy Service allows administrators to define constraints that control how Google Cloud resources can be configured throughout an organization. Policies can help enforce organizational requirements, such as restricting resource locations, limiting certain resource types, or controlling configuration options. These policies can apply at organization, folder, or project levels and can be inherited by lower-level resources. Cloud Profiler analyzes application performance, Cloud Trace analyzes request latency, and Cloud Scheduler runs recurring jobs. Therefore, when an organization needs centralized governance and configuration restrictions across Google Cloud resources, Organization Policy Service is the appropriate solution.

Q207. Which Google Cloud feature allows administrators to estimate spending and receive notifications when costs approach a configured threshold?

1) Cloud Billing budgets and alerts
2) Cloud Monitoring uptime checks
3) Cloud DNS policies
4) Pub/Sub subscriptions

Correct Answer: 1)

Explanation:

Cloud Billing budgets and alerts help organizations monitor cloud spending against predefined budget amounts. Administrators can configure budgets for different scopes and set threshold percentages that trigger notifications as spending approaches or exceeds selected levels. Budgets themselves do not automatically stop resource usage or prevent charges; they are primarily monitoring and notification mechanisms. Cloud Monitoring uptime checks verify service availability, Cloud DNS manages DNS behavior, and Pub/Sub subscriptions receive messages. Therefore, when the requirement is to track spending and receive notifications at specified cost thresholds, Cloud Billing budgets and alerts provide the appropriate functionality.

Q208. Which IAM principal represents a collection of users that can be managed together?

1) Google Group
2) Service account key
3) VPC subnet
4) Compute Engine image

Correct Answer: 1)

Explanation:

A Google Group can be used as an IAM principal to simplify permission management for multiple users. Instead of assigning the same role separately to every individual, an administrator can add users to a group and grant the required IAM role to that group. When membership changes, access can be updated by modifying the group rather than changing resource-level IAM policies repeatedly. Service account keys are credentials, VPC subnets define network ranges, and Compute Engine images contain VM disk information. Therefore, when multiple users need common access that should be managed centrally, a Google Group is an effective IAM principal.

Q209. What is the recommended approach when an application running on Compute Engine needs to call Google Cloud APIs?

1) Store a service account key inside the source code
2) Attach an appropriate service account to the VM
3) Make the VM publicly accessible
4) Disable IAM permissions

Correct Answer: 2)

Explanation:

Attaching an appropriate service account to a Compute Engine VM allows applications running on that VM to authenticate to Google Cloud APIs using the VM’s identity. Administrators can grant the service account only the permissions required by the workload, following the principle of least privilege. This approach is generally preferable to storing long-lived service account keys in source code or on disk. Public network access is not inherently required for authentication to Google Cloud APIs. Therefore, when a Compute Engine application needs access to Google Cloud services, attaching a properly permissioned service account to the VM is the recommended approach.

Q210. Which authentication method can allow workloads outside Google Cloud to access Google Cloud resources without requiring long-lived service account keys?

1) Workload Identity Federation
2) Cloud Storage Lifecycle Management
3) Cloud DNS
4) VPC Firewall Rules

Correct Answer: 1)

Explanation:

Workload Identity Federation allows external workloads to obtain temporary Google Cloud credentials by using identities from supported external identity providers. This approach can reduce the need to create and distribute long-lived service account keys. It is particularly useful for workloads running outside Google Cloud, such as applications in another cloud provider, on-premises environments, or supported CI/CD systems. Administrators can establish trust relationships and grant the external identity appropriate permissions. Cloud Storage Lifecycle Management manages objects, Cloud DNS manages DNS records, and firewall rules control network traffic. Therefore, Workload Identity Federation is the appropriate solution for external workloads requiring secure Google Cloud access without long-lived keys.

Q211. Which command-line tool is commonly used to manage Google Cloud resources from a terminal?

1) gcloud CLI
2) kubectl only
3) npm
4) git

Correct Answer: 1)

Explanation:

The Google Cloud CLI, commonly accessed through the gcloud command, provides command-line tools for managing many Google Cloud resources. Administrators can use it to create and modify Compute Engine instances, configure projects, manage IAM settings, deploy workloads, and perform many other operations. Other tools can complement the Google Cloud CLI. For example, kubectl is specifically designed for interacting with Kubernetes clusters, while npm manages JavaScript packages and Git manages source code repositories. Therefore, when the question asks for the general command-line tool used to manage Google Cloud resources, the gcloud CLI is the correct answer.

Q212. Which Google Cloud environment provides a browser-based shell with the Google Cloud CLI and commonly used development tools already installed?

1) Cloud Shell
2) Cloud Storage
3) Cloud SQL
4) Cloud CDN

Correct Answer: 1)

Explanation:

Cloud Shell provides an online command-line environment that can be accessed through the Google Cloud console. It includes the Google Cloud CLI and commonly used development and administration tools, allowing users to manage resources without installing a local command-line environment. Cloud Shell is particularly useful when working from different computers or when a temporary, ready-to-use administrative environment is needed. Cloud Storage provides object storage, Cloud SQL provides managed relational databases, and Cloud CDN provides content caching. Therefore, when a user needs a browser-based terminal with Google Cloud management tools already available, Cloud Shell is the appropriate choice.

Q213. Which Compute Engine resource defines the configuration used to create multiple similar VM instances?

1) Instance template
2) Cloud DNS zone
3) BigQuery dataset
4) Pub/Sub subscription

Correct Answer: 1)

Explanation:

An instance template defines the configuration for Compute Engine virtual machine instances. It can specify settings such as machine type, boot disk configuration, network interfaces, service accounts, labels, and other VM properties. Managed instance groups commonly use instance templates to create and maintain multiple VM instances with consistent configurations. This makes templates particularly useful for scalable and repeatable deployments. Cloud DNS zones manage DNS information, BigQuery datasets organize analytical data, and Pub/Sub subscriptions receive messages. Therefore, when an organization needs a reusable VM configuration for creating multiple similar instances, an instance template is the appropriate Compute Engine resource.

Q214. Which managed instance group feature can replace an unhealthy VM automatically?

1) Autohealing
2) Cloud NAT
3) Cloud Storage Versioning
4) BigQuery clustering

Correct Answer: 1)

Explanation:

Managed instance group autohealing can automatically recreate VM instances that fail configured health checks. A health check determines whether an instance is responding as expected, and if an instance is considered unhealthy for the required conditions, the managed instance group can recreate it using the group’s instance template. This improves application resilience by reducing the need for administrators to manually replace failed instances. Cloud NAT handles outbound network access, Cloud Storage Versioning maintains previous object versions, and BigQuery clustering organizes table data for query efficiency. Therefore, autohealing is the managed instance group capability used to replace unhealthy VM instances automatically.

Q215. Which feature allows a managed instance group to increase or decrease the number of VM instances according to workload demand?

1) Autoscaling
2) Cloud DNS
3) IAM Conditions
4) Object Versioning

Correct Answer: 1)

Explanation:

Managed instance group autoscaling adjusts the number of VM instances according to workload demand and configured scaling policies. Depending on the configuration, scaling can consider signals such as CPU utilization or other supported metrics. When demand increases, additional instances can be created, while lower demand can cause the group to reduce the number of instances. This allows applications to respond dynamically to changing workloads while helping control resource usage. Cloud DNS manages domain names, IAM Conditions control conditional access, and Object Versioning applies to Cloud Storage objects. Therefore, autoscaling is the feature designed to dynamically adjust the size of a managed instance group.

Q216. Which Compute Engine storage option provides persistent block storage that remains available independently of the VM lifecycle?

1) Persistent Disk
2) Temporary RAM
3) Cloud DNS
4) Pub/Sub topic

Correct Answer: 1)

Explanation:

Persistent Disk provides durable block storage that can be attached to Compute Engine VM instances. The data stored on a persistent disk is designed to remain available independently of the lifecycle of the VM instance, allowing disks to be detached and attached to other instances when appropriate. Persistent disks are commonly used for operating system disks, application data, and workloads requiring durable block storage. Temporary memory does not provide persistent storage, while Cloud DNS and Pub/Sub serve networking and messaging functions. Therefore, when a Compute Engine workload requires durable block storage that is independent of the VM lifecycle, Persistent Disk is the appropriate choice.

Q217. Which Compute Engine storage feature can create a point-in-time copy of a persistent disk for backup or recovery purposes?

1) Persistent Disk snapshot
2) Cloud DNS record
3) Pub/Sub subscription
4) VPC route

Correct Answer: 1)

Explanation:

A Persistent Disk snapshot creates a point-in-time copy of data stored on a persistent disk. Snapshots are useful for backup, recovery, migration, and creating new disks based on an existing disk state. They can help administrators protect important VM data and provide a recovery option if the original disk becomes corrupted or data is accidentally removed. VPC routes control network packet forwarding, Pub/Sub subscriptions receive messages, and Cloud DNS records provide name-resolution information. Therefore, when an administrator needs a point-in-time copy of a persistent disk for backup or recovery, a persistent disk snapshot is the appropriate feature.

Q218. Which networking component dynamically exchanges routes between Google Cloud and an external network using BGP?

1) Cloud Router
2) Cloud Storage
3) Cloud Scheduler
4) Secret Manager

Correct Answer: 1)

Explanation:

Cloud Router uses the Border Gateway Protocol, or BGP, to dynamically exchange network routes between Google Cloud VPC networks and supported external networks. It is commonly used with Cloud VPN and Cloud Interconnect to allow routing information to be exchanged automatically instead of requiring administrators to maintain static routes manually. Dynamic route exchange can make hybrid network environments easier to operate and adapt as network topology changes. Cloud Storage manages objects, Cloud Scheduler runs recurring jobs, and Secret Manager stores sensitive values. Therefore, Cloud Router is the networking component responsible for dynamic BGP-based route exchange.

Q219. Which VPC networking concept determines the IP range available for resources deployed in a subnet?

1) Subnet IP range
2) IAM role
3) Cloud Billing budget
4) Pub/Sub topic

Correct Answer: 1)

Explanation:

A VPC subnet has an IP address range that determines the addresses available to resources deployed within that subnet. When creating or configuring a subnet, administrators specify a primary IP range and can configure additional ranges for supported workloads. Careful subnet planning helps prevent address conflicts and ensures sufficient capacity for current and future resources. IAM roles control permissions, Cloud Billing budgets track spending, and Pub/Sub topics handle asynchronous messaging. Therefore, when the question asks what determines the IP address range available within a subnet, the subnet IP range is the correct answer.

Q220. Which Google Cloud networking feature can connect two VPC networks using internal IP addresses without requiring public internet connectivity?

1) VPC Network Peering
2) Cloud CDN
3) Cloud Scheduler
4) Cloud Storage

Correct Answer: 1)

Explanation:

VPC Network Peering allows two VPC networks to communicate using internal IP addresses, provided the networks and configurations meet the applicable peering requirements. This can enable private communication between workloads in separate VPC networks without sending traffic through the public internet. Peering is useful when organizations need private connectivity between networks while keeping resources addressed through internal IP ranges. Cloud CDN provides content caching, Cloud Scheduler handles scheduled jobs, and Cloud Storage provides object storage. Therefore, when the requirement is to connect two VPC networks through private internal IP connectivity, VPC Network Peering is the appropriate networking feature.
