Question 361

Which Google Cloud service provides centralized visibility into network topology?

1. Cloud Trace
2. Error Reporting
3. Cloud Profiler
4. Network Intelligence Center

Correct Answer: 4

Explanation:

Network Intelligence Center provides centralized tools for analyzing and understanding Google Cloud network environments. Its capabilities can help administrators examine network topology, troubleshoot connectivity, monitor performance, and identify configuration-related issues. This centralized visibility is valuable in complex environments containing multiple VPC networks, regions, projects, and hybrid connections. Cloud Trace focuses on distributed application tracing, Error Reporting identifies application errors, and Cloud Profiler analyzes application performance. Network Intelligence Center is therefore the appropriate service when the requirement involves understanding network structure and connectivity relationships across a Google Cloud environment.

Question 362

Which VPC feature allows resources to communicate using IPv6 addresses?

1. IPv6 subnet ranges
2. Cloud NAT rules
3. BGP communities
4. DNS forwarding targets

Correct Answer: 1

Explanation:

IPv6 subnet ranges enable supported Google Cloud VPC resources to use IPv6 addressing. Depending on the network architecture and resource support, IPv6 can provide additional address capacity and enable modern dual-stack or IPv6-focused deployments. IPv6 configuration must be planned carefully because address assignment, routing, firewall behavior, and workload compatibility all affect connectivity. Cloud NAT rules are related to address translation, BGP communities influence route attributes, and DNS forwarding targets determine where DNS queries are sent. Therefore, IPv6 subnet ranges are the networking feature directly associated with assigning IPv6 address space within a VPC.

Question 363

What does a route’s priority influence in Google Cloud VPC routing?

1. DNS response selection
2. Firewall logging frequency
3. Selection between applicable routes
4. Load-balancer health checks

Correct Answer: 3

Explanation:

Route priority helps determine which applicable route is selected when multiple routes can potentially reach the same destination. Google Cloud evaluates routing information according to its routing rules, including destination specificity and route priority where applicable. Administrators can use route priorities to influence forwarding behavior when routes overlap appropriately. DNS response selection is handled by DNS configuration, firewall logging frequency is unrelated to route selection, and load-balancer health checks determine backend availability rather than VPC route choice. Understanding route priority is important when troubleshooting unexpected traffic paths or designing environments containing multiple static or dynamic routing sources.

Question 364

Which component attaches a VLAN configuration to Dedicated Interconnect connectivity?

1. Cloud DNS zone
2. VLAN attachment
3. Firewall endpoint
4. Service directory namespace

Correct Answer: 2

Explanation:

A VLAN attachment connects a VPC network to a Dedicated Interconnect connection through a configured VLAN. It provides the logical connectivity needed for exchanging traffic between Google Cloud and an external network over the Interconnect infrastructure. VLAN attachments are associated with Cloud Router configurations so that dynamic routing can operate across the connection. Cloud DNS zones manage name resolution, firewall endpoints are unrelated to Interconnect configuration, and Service Directory namespaces provide service discovery capabilities. Consequently, when an architecture requires a logical attachment between a VPC and Dedicated Interconnect, the appropriate resource is a VLAN attachment.

Question 365

Which service can provide private access to Google APIs from supported serverless workloads?

1. Cloud Scheduler
2. Cloud Tasks
3. Private Google Access
4. Artifact Registry

Correct Answer: 3

Explanation:

Private Google Access enables eligible resources without external IP addresses to reach supported Google APIs and services through private connectivity. This capability can be relevant to architectures where workloads need Google-managed services while avoiding direct public IP exposure. Serverless networking configurations may use additional connectivity components depending on the service and deployment model, but Private Google Access addresses the requirement for private access to supported Google APIs. Cloud Scheduler manages scheduled jobs, Cloud Tasks handles asynchronous task delivery, and Artifact Registry stores software artifacts. Those services do not provide the underlying private Google API access mechanism.

Question 366

Which VPN architecture provides multiple tunnels for higher availability?

1. HA VPN
2. Classic static routing
3. Public DNS forwarding
4. Internet Network Endpoint Group

Correct Answer: 1

Explanation:

HA VPN is designed to provide highly available VPN connectivity by using redundant tunnels and appropriate interface configurations. It works with Cloud Router and BGP to support dynamic route exchange in supported architectures. Redundant tunnel design helps reduce dependency on a single tunnel and can improve resilience when one connectivity path becomes unavailable. Classic static routing does not provide the same high-availability architecture, public DNS forwarding concerns name resolution, and an Internet Network Endpoint Group represents a load-balancing backend construct. HA VPN is therefore the appropriate choice when resilient encrypted hybrid connectivity is required.

Question 367

Which Google Cloud construct identifies a collection of VM instances for firewall targeting?

1. DNS policy
2. Network tag
3. Cloud Router interface
4. Interconnect circuit

Correct Answer: 2

Explanation:

Network tags can be applied to Google Cloud VM instances and can be referenced by applicable firewall rules to identify target resources. This allows administrators to associate security policies with groups of instances without necessarily specifying every VM individually. Tags can represent application roles or other logical classifications, making them useful for controlling which instances a rule affects. DNS policies manage DNS behavior, Cloud Router interfaces support routing connections, and Interconnect circuits provide connectivity infrastructure. Network tags are therefore useful when firewall targeting needs to follow VM groupings based on logical workload characteristics.

Question 368

What does a Cloud Router BGP session primarily exchange?

1. TLS certificates
2. DNS resource records
3. IP routing information
4. Application cookies

Correct Answer: 3

Explanation:

A Cloud Router BGP session exchanges IP routing information between Google Cloud and a connected network. BGP allows each side to advertise reachable prefixes and learn routes dynamically. This is especially useful for hybrid connectivity because routing changes can propagate without requiring administrators to manually maintain every route. TLS certificates are used for secure application communication, DNS resource records contain name-resolution information, and application cookies belong to application-layer communication. Cloud Router operates at the routing control plane and therefore uses BGP to exchange network reachability information rather than application or DNS data.

Question 369

Which feature can prevent a subnet from being accidentally deleted?

1. Cloud Monitoring alert
2. DNSSEC configuration
3. Deletion protection
4. Packet capture session

Correct Answer: 3

Explanation:

Deletion protection can help prevent accidental removal of supported Google Cloud resources by requiring the protection setting to be addressed before deletion can proceed. This is useful for infrastructure components where unintended deletion could cause service disruption or loss of connectivity. Cloud Monitoring alerts provide operational notifications, DNSSEC protects DNS authenticity, and packet capture sessions are used for traffic analysis. Deletion protection does not replace access controls or change the permissions required to manage resources, but it provides an additional safeguard against accidental resource removal when supported by the resource type.

Question 370

Which Google Cloud service provides managed external DNS hosting?

1. Cloud DNS
2. Cloud Logging
3. Cloud Build
4. Cloud Deploy

Correct Answer: 1

Explanation:

Cloud DNS is Google’s managed DNS service and can host public DNS zones that contain records used by internet-facing applications and services. It provides scalable authoritative DNS infrastructure without requiring organizations to operate their own DNS servers. Cloud Logging collects and analyzes log data, Cloud Build provides build automation, and Cloud Deploy manages application deployment workflows. When an organization needs managed authoritative DNS for domains accessible externally, Cloud DNS is the relevant Google Cloud service. DNS configuration can also coexist with private zones and other DNS features depending on the overall network architecture.

Question 371

Which routing protocol is commonly used between Cloud Router and on-premises routers?

1. OSPF
2. EIGRP
3. BGP
4. IS-IS

Correct Answer: 3

Explanation:

Cloud Router uses Border Gateway Protocol for dynamic route exchange with supported connected networks. BGP allows Cloud Router and an external router to advertise and learn IP prefixes dynamically. This is a fundamental part of hybrid networking architectures involving HA VPN, Dedicated Interconnect, Partner Interconnect, and related connectivity configurations. OSPF, EIGRP, and IS-IS are routing protocols used in various traditional networking environments, but they are not the dynamic routing protocol used by Cloud Router for these Google Cloud connectivity scenarios. Correct BGP configuration is therefore essential when dynamic route exchange is required.

Question 372

Which service provides managed private connectivity to a producer’s published service?

1. Private Service Connect
2. Cloud Workstations
3. Cloud Shell
4. Batch

Correct Answer: 1

Explanation:

Private Service Connect allows service consumers to access supported published services through private connectivity. Instead of requiring consumers to establish broad network-level connectivity to the producer’s VPC, the service can be exposed through a controlled private endpoint or attachment model. This helps preserve network isolation while enabling service consumption. Cloud Workstations provides managed development environments, Cloud Shell provides a browser-based command-line environment, and Batch manages large-scale batch workloads. None of those services provides the service-consumer connectivity model offered by Private Service Connect.

Question 373

Which load-balancing component determines whether a backend is serving traffic successfully?

1. Forwarding rule
2. Health check
3. Route advertisement
4. Backend firewall tag

Correct Answer: 2

Explanation:

A health check evaluates whether a backend is responding according to the configured health-check criteria. Load balancers use health information to determine which backends are eligible to receive traffic. This prevents requests from being directed toward backends that are unavailable or failing the required checks. A forwarding rule determines how incoming traffic is directed toward a load-balancing configuration, while route advertisements influence network reachability. A firewall tag can help identify instances for security rules but does not determine backend health. Therefore, health checks are the component responsible for backend availability evaluation.

Question 374

Which network design allows separate projects to share centrally managed subnets?

1. Cloud CDN architecture
2. VPC Service Controls
3. Shared VPC
4. Cloud Armor policy

Correct Answer: 3

Explanation:

Shared VPC allows an organization to maintain a host project containing the VPC network and make selected subnets available to attached service projects. This enables application teams to deploy resources into centrally managed network infrastructure while network administrators retain control over important networking components. It is useful for organizations that want project-level separation for workloads without creating completely independent VPC networks for every project. Cloud CDN focuses on content delivery, VPC Service Controls provide service-perimeter controls, and Cloud Armor provides security policies for supported applications. Shared VPC specifically addresses centralized network sharing across projects.

Question 375

Which mechanism can connect multiple VPC networks through a centralized hub?

1. Network Connectivity Center
2. Cloud NAT
3. Cloud CDN
4. Cloud DNSSEC

Correct Answer: 1

Explanation:

Network Connectivity Center provides a hub-and-spoke framework for connecting supported network resources. Organizations can use it to establish centralized connectivity between multiple VPC networks and supported hybrid networking resources. This architecture can simplify large-scale connectivity compared with maintaining numerous independent point-to-point relationships. Cloud NAT handles outbound address translation, Cloud CDN distributes cached content, and DNSSEC provides authentication for DNS responses. Network Connectivity Center therefore addresses centralized network connectivity rather than application delivery, address translation, or DNS security.

Question 376

Which resource controls whether a VM can receive traffic on a specific TCP port?

1. Cloud Router advertisement
2. Firewall rule
3. DNS record set
4. NAT IP pool

Correct Answer: 2

Explanation:

A VPC firewall rule can allow or deny traffic based on criteria such as protocol, port, direction, source, destination, and target resources. For example, an ingress rule can permit TCP traffic to a specific application port for selected VM instances. Firewall rules therefore provide the network-level access control needed to regulate whether traffic can reach a VM. Cloud Router advertisements manage route exchange, DNS record sets map names to data, and NAT IP pools support address translation. Consequently, when the requirement concerns permitting or blocking traffic on a particular TCP port, firewall rules are the relevant control.

Question 377

Which feature helps identify the path packets are expected to take through Google Cloud networking?

1. Cloud Storage Transfer
2. Network Topology
3. Secret Manager
4. Cloud Composer

Correct Answer: 2

Explanation:

Network Topology, available through Network Intelligence Center, provides a visual representation of relationships among network resources and connectivity paths. It can help administrators understand how VPC networks, instances, load balancers, hybrid connections, and other supported components relate to each other. This visibility is useful when analyzing complex architectures or investigating unexpected traffic behavior. Cloud Storage Transfer moves data between storage environments, Secret Manager stores sensitive configuration information, and Cloud Composer manages workflow orchestration. Network Topology is therefore the feature specifically associated with visualizing network relationships and understanding the broader structure of a Google Cloud network.

Question 378

Which Interconnect option uses a supported service provider instead of a direct physical connection?

1. Dedicated Interconnect
2. HA VPN
3. Partner Interconnect
4. Private Google Access

Correct Answer: 3

Explanation:

Partner Interconnect provides connectivity to Google Cloud through a supported service provider. It is useful when an organization needs private connectivity but does not establish a direct Dedicated Interconnect connection at a Google-approved colocation facility. The service provider supplies the connectivity path, while Google Cloud resources such as VLAN attachments and Cloud Router support the cloud-side configuration. Dedicated Interconnect uses a direct physical connection, HA VPN establishes encrypted tunnels, and Private Google Access enables private access to supported Google services. Partner Interconnect therefore fits architectures that rely on an approved connectivity provider.

Question 379

Which Google Cloud feature can analyze whether firewall rules permit a connectivity attempt?

1. Connectivity Tests
2. Cloud Scheduler
3. Artifact Registry
4. Cloud Functions

Correct Answer: 1

Explanation:

Connectivity Tests can analyze network reachability and evaluate configuration elements that influence whether traffic can successfully travel between supported endpoints. Firewall rules are among the important controls considered during connectivity analysis. This makes Connectivity Tests useful when an administrator needs to determine why traffic is being blocked or whether a particular network path should be available. Cloud Scheduler manages scheduled operations, Artifact Registry stores packages and container images, and Cloud Functions provides event-driven compute. Those services do not perform network-path analysis. Connectivity Tests therefore provide a focused troubleshooting mechanism for connectivity and firewall-related issues.

Question 380

Which Google Cloud feature can export VPC flow information for analysis outside the VPC?

1. Cloud NAT logging
2. VPC Flow Logs integration
3. Cloud CDN cache statistics
4. Cloud DNS query forwarding

Correct Answer: 2

Explanation:

VPC Flow Logs generate network traffic metadata that can be collected and analyzed through Google Cloud’s logging and monitoring ecosystem. This information can support security investigations, traffic analysis, capacity planning, and troubleshooting. Depending on the configured architecture, flow-log information can be routed for additional processing or analysis outside the immediate VPC environment. Cloud NAT logging focuses on NAT activity, Cloud CDN cache statistics concern content delivery performance, and Cloud DNS query forwarding handles DNS requests. VPC Flow Logs are therefore the appropriate feature when network-flow metadata needs to be collected for broader analysis.
