Question 81

A company has multiple Google Cloud projects and wants to centralize networking for several application teams. Which architecture should it consider?

1. Separate public IPs for every VM
2. Shared VPC
3. Cloud CDN
4. Cloud Storage replication

Correct Answer: 2

Explanation

Shared VPC allows an organization to centrally manage networking resources in a host project while allowing workloads in attached service projects to use those networks. This model is useful when a central networking team needs control over subnets, routes, and firewall policies while application teams manage their own workloads. It can improve consistency and simplify governance across multiple projects. Cloud CDN, public IP addresses, and Cloud Storage replication address different requirements. Therefore, Shared VPC is appropriate when multiple projects need centralized network management.

Question 82

Which Google Cloud service provides a managed Kubernetes environment?

1. Google Kubernetes Engine
2. Cloud SQL
3. BigQuery
4. Cloud Composer

Correct Answer: 1

Explanation

Google Kubernetes Engine (GKE) is Google’s managed Kubernetes service for deploying and operating containerized applications. It provides Kubernetes control-plane management and supports features for workload scheduling, scaling, networking, security, and observability. Organizations can choose between different operational models depending on how much infrastructure management they want to handle. Cloud SQL is a relational database service, BigQuery is a data warehouse, and Cloud Composer is a managed workflow orchestration service. Therefore, GKE is the appropriate choice for running Kubernetes workloads on Google Cloud.

Question 83

A security team wants to prevent resources from being created in unapproved geographic locations. Which control is most appropriate?

1. Organization Policy constraint
2. Cloud Monitoring alert
3. Pub/Sub subscription
4. Cloud Trace configuration

Correct Answer: 1

Explanation

Organization Policy constraints can enforce centralized governance requirements across Google Cloud resource hierarchies. A location-related constraint can restrict where certain resources are permitted to be created, helping organizations satisfy regulatory, residency, or internal governance requirements. Unlike a monitoring alert, an organization policy can actively prevent prohibited configurations rather than merely report them after deployment. Pub/Sub handles messaging and Cloud Trace provides distributed tracing. Therefore, an Organization Policy constraint is the appropriate preventive control for restricting resource locations.

Question 84

A workload on Compute Engine requires persistent block storage that remains available after a VM restarts. Which storage option should be used?

1. Persistent Disk
2. Local SSD only
3. Cloud CDN
4. Memorystore

Correct Answer: 1

Explanation

Persistent Disk provides durable block storage that is independent of the lifecycle of an individual VM instance. Data stored on a Persistent Disk can remain available when a VM is stopped or restarted and can be attached to supported compute resources according to the selected configuration. Local SSD provides high-performance temporary storage and is tied more closely to the VM lifecycle. Cloud CDN is a content-delivery service, while Memorystore provides in-memory caching. Therefore, Persistent Disk is the appropriate choice for durable block storage required by a Compute Engine workload.

Question 85

A company wants private access from VMs to Google APIs without assigning external IP addresses to those VMs. Which capability should the architect consider?

1. Private Google Access
2. Cloud CDN
3. External HTTP Load Balancing
4. Public DNS forwarding

Correct Answer: 1

Explanation

Private Google Access allows eligible resources without external IP addresses to access supported Google APIs and services through private connectivity. This can reduce the need to expose workloads directly to the public internet while allowing applications to interact with services such as Cloud Storage and other Google APIs. External load balancing and public DNS serve different connectivity purposes, while Cloud CDN focuses on content delivery. Therefore, Private Google Access should be considered when VMs need access to Google APIs without requiring external IP addresses.

Question 86

Which Google Cloud service is designed for distributed workflow orchestration using managed workflows based on Apache Airflow?

1. Cloud Composer
2. Cloud Run
3. Cloud Armor
4. Cloud Router

Correct Answer: 1

Explanation

Cloud Composer is a managed workflow orchestration service built around Apache Airflow. It allows teams to create, schedule, monitor, and manage workflows that coordinate tasks across data processing and other cloud services. It is particularly useful when workflows contain dependencies between multiple steps and need centralized scheduling and orchestration. Cloud Run executes containers, Cloud Armor provides application protection, and Cloud Router exchanges dynamic routing information. Therefore, Cloud Composer is the appropriate service for managed Apache Airflow-based workflow orchestration.

Question 87

A global application needs users to connect to the nearest available Google Cloud frontend while maintaining a single global endpoint. Which design should the architect consider?

1. Global external Application Load Balancer
2. Regional internal load balancer only
3. Single VM with a static IP
4. Cloud Storage bucket without a load balancer

Correct Answer: 1

Explanation

A global external Application Load Balancer can provide a single global frontend while distributing traffic to appropriate backends based on the configured architecture and health status. This is useful for applications serving users across multiple geographic locations because traffic can be directed toward suitable healthy backends rather than relying on one regional endpoint. A single VM introduces a single point of failure, while a regional internal load balancer is intended for different connectivity scenarios. Therefore, a global external Application Load Balancer is appropriate for a globally accessible application requiring a unified endpoint.

Question 88

A company wants to transfer a large amount of data from an existing object-storage environment into Cloud Storage and schedule recurring transfers. Which service should it use?

1. Storage Transfer Service
2. Cloud Trace
3. Cloud KMS
4. Cloud Scheduler alone

Correct Answer: 1

Explanation

Storage Transfer Service is designed to move large amounts of data into Cloud Storage from supported sources, including other cloud storage environments and on-premises locations. It supports managed transfer jobs and can automate recurring transfers according to configured schedules. This makes it more suitable than manually copying objects or using a general scheduling service alone. Cloud Trace is used for application tracing, Cloud KMS manages cryptographic keys, and Cloud Scheduler only schedules tasks. Therefore, Storage Transfer Service is the appropriate choice for recurring large-scale object transfers.

Question 89

Which database is generally suited for very high-throughput key-value workloads with predictable low-latency access at large scale?

1. Bigtable
2. Cloud SQL
3. Firestore
4. Cloud Storage

Correct Answer: 1

Explanation

Bigtable is a fully managed NoSQL database designed for large-scale analytical and operational workloads requiring high throughput and low-latency access. It is particularly suitable for massive key-value or wide-column datasets such as time-series information, telemetry, and large operational datasets. Cloud SQL provides managed relational databases, Firestore is a document-oriented NoSQL database, and Cloud Storage is object storage rather than a database. Therefore, Bigtable is generally appropriate for very high-throughput key-value workloads that require predictable performance at significant scale.

Question 90

A company needs to securely connect its on-premises network to Google Cloud using an encrypted tunnel over the public internet. Which solution should it consider?

1. Cloud VPN
2. Cloud CDN
3. Cloud Storage
4. Cloud DNS

Correct Answer: 3

Explanation

Cloud VPN provides encrypted connectivity between an on-premises network and Google Cloud over the public internet. It is useful when organizations need secure hybrid connectivity without deploying a dedicated private physical connection. Depending on availability and architecture requirements, HA VPN can provide higher availability than a basic single-tunnel design. Cloud CDN distributes content, Cloud Storage stores objects, and Cloud DNS manages name resolution. Therefore, Cloud VPN is the appropriate solution when encrypted site-to-site connectivity over the public internet is required.

Question 91

A company requires dedicated private connectivity between its data center and Google Cloud with predictable network performance. Which option should be evaluated?

1. Cloud Interconnect
2. Cloud NAT
3. Cloud CDN
4. Public DNS

Correct Answer: 1

Explanation

Cloud Interconnect provides private connectivity between an organization’s network and Google Cloud. It can be appropriate for workloads requiring high bandwidth, predictable network performance, or reduced dependence on the public internet. Depending on the architecture and connectivity provider, organizations can use Dedicated or Partner Interconnect. Cloud NAT provides outbound internet access for resources without external IP addresses, while Cloud CDN accelerates content delivery. Public DNS does not provide private network connectivity. Therefore, Cloud Interconnect should be evaluated for dedicated hybrid connectivity requirements.

Question 92

A development team wants to deploy containers without managing Kubernetes clusters or VM instances. Which service is most appropriate for a stateless HTTP application?

1. Compute Engine
2. Cloud Run
3. GKE Standard
4. Bare Metal Solution

Correct Answer: 2

Explanation

Cloud Run provides a managed environment for running containerized applications without requiring the development team to manage VM instances or Kubernetes clusters. It is particularly suitable for stateless HTTP services that can scale according to incoming demand. Compute Engine requires VM management, while GKE Standard requires Kubernetes infrastructure management and operational expertise. Bare Metal Solution is intended for specialized workloads requiring dedicated physical infrastructure. Therefore, Cloud Run is the appropriate choice when a team wants to deploy a stateless containerized HTTP application with minimal infrastructure management.

Question 93

A company needs to allow a workload to access Google Cloud resources using a specific identity without giving developers permanent service account keys. Which approach should be preferred?

1. Service account impersonation
2. Shared administrator passwords
3. Hard-coded JSON keys
4. Anonymous access

Correct Answer: 1

Explanation

Service account impersonation allows an authorized identity to act as a service account temporarily and obtain short-lived credentials instead of relying on long-lived service account keys. This reduces the risk associated with storing and distributing permanent credentials and provides more controlled access. Hard-coded JSON keys can become difficult to rotate and protect, while shared passwords and anonymous access provide poor identity management. Therefore, service account impersonation is a preferred approach when workloads or administrators need to operate using a specific service account without distributing permanent keys.

Question 94

Which Google Cloud feature allows DNS records to be used only within a private VPC environment?

1. Private Cloud DNS zone
2. Public IP address
3. Cloud CDN
4. External load balancer

Correct Answer: 1

Explanation

A private Cloud DNS zone provides DNS name resolution within selected VPC networks rather than exposing those records publicly on the internet. This is useful for internal applications, private service endpoints, and workloads that need internal DNS names. Organizations can use private zones to create consistent internal naming without making internal addresses publicly resolvable. Public IP addresses, Cloud CDN, and external load balancers serve different purposes. Therefore, a private Cloud DNS zone is appropriate when DNS records should be available only to resources within a private VPC environment.

Question 95

A company is designing a new application and wants separate Google Cloud projects for development, testing, and production. What is a major benefit of this approach?

1. Stronger resource and access isolation
2. Eliminates all IAM requirements
3. Prevents all application failures
4. Removes the need for monitoring

Correct Answer: 1

Explanation

Separating development, testing, and production into different projects can provide stronger resource, access, billing, and administrative isolation. IAM permissions can be scoped appropriately so that developers do not automatically receive broad access to production resources. Project separation can also simplify quota management, auditing, and cost visibility. However, separate projects do not eliminate IAM, monitoring, or application failures. They are a governance and isolation mechanism rather than a guarantee of reliability. Therefore, stronger resource and access isolation is a major benefit of using separate projects.

Question 96

Which capability helps prevent unauthorized services or resource types from being deployed across an organization?

1. Organization Policy
2. Cloud Trace
3. Cloud CDN
4. BigQuery reservations

Correct Answer: 1

Explanation

Organization Policy can enforce centralized constraints on resource configurations and supported services throughout an organization’s resource hierarchy. Administrators can use appropriate constraints to restrict certain resource types or configurations according to organizational governance requirements. This provides preventive control instead of relying solely on after-the-fact monitoring. Cloud Trace focuses on distributed application tracing, Cloud CDN accelerates content delivery, and BigQuery reservations manage analytical compute capacity. Therefore, Organization Policy is the appropriate governance capability for restricting prohibited resource configurations or deployments.

Question 97

A company wants to improve reliability by defining a target percentage of successful requests and monitoring whether the application meets that target. What should the team establish?

1. SLO
2. Firewall rule
3. Storage class
4. IAM binding

Correct Answer: 3

Explanation

A Service Level Objective (SLO) defines a measurable reliability target for a service, such as a required percentage of successful requests or an acceptable latency threshold. Teams can monitor performance against the SLO and use the resulting information to guide reliability decisions. SLOs are often supported by Service Level Indicators (SLIs), which provide the measurements used to evaluate performance. Firewall rules control network traffic, storage classes define storage characteristics, and IAM bindings control authorization. Therefore, establishing an SLO is appropriate when defining measurable application reliability targets.

Question 98

A company has a workload with predictable resource usage throughout the year and wants to reduce compute costs by committing to a consistent usage level. Which option should it evaluate?

1. Committed use discounts
2. Cloud CDN
3. Cloud DNS
4. Pub/Sub subscriptions

Correct Answer: 1

Explanation

Committed use discounts can reduce eligible Google Cloud costs when an organization commits to a specified level of resource usage for a defined period. They are generally more appropriate for workloads with predictable and sustained usage because the organization can make use of the committed capacity over the commitment term. Highly variable workloads may require different cost-optimization strategies. Cloud CDN, Cloud DNS, and Pub/Sub address content delivery, DNS, and messaging rather than compute commitment pricing. Therefore, committed use discounts should be evaluated for predictable long-term compute usage.

Question 99

A security team wants to reduce the risk of sensitive data moving between Google Cloud services outside approved security boundaries. Which service should be evaluated?

1. VPC Service Controls
2. Cloud Scheduler
3. Cloud Trace
4. Cloud Deploy

Correct Answer: 1

Explanation

VPC Service Controls can help create security perimeters around supported Google Cloud services and reduce the risk of unauthorized data exfiltration. The controls can restrict access to protected resources based on defined perimeter rules and access conditions. This is particularly useful for organizations handling sensitive information that need additional protection beyond identity-based IAM controls. Cloud Scheduler manages scheduled jobs, Cloud Trace provides tracing, and Cloud Deploy manages application delivery. Therefore, VPC Service Controls should be evaluated when reducing data-exfiltration risk is a key security requirement.

Question 100

A company needs to recover an application quickly after a regional disaster and has defined a maximum acceptable data loss of five minutes. Which requirement does the five-minute limit represent?

1. RTO
2. RPO
3. SLA
4. SLI

Correct Answer: 2

Explanation

Recovery Point Objective (RPO) defines the maximum amount of data loss that an organization is willing to tolerate after a failure. A five-minute RPO means the recovery strategy should aim to ensure that no more than approximately five minutes of data is lost. Recovery Time Objective (RTO), in contrast, defines how quickly the service should be restored after disruption. SLA represents a service-level agreement, while SLI is a measurable indicator used to assess service performance. Therefore, the five-minute maximum data-loss requirement represents the RPO.
