Question 281

Which Cloud DNS feature lets records return different answers based on request geography?

1. DNSSEC signing
2. Forwarding policy
3. Geolocation routing policy
4. DNS peering

Correct Answer: 3

Explanation:

A Cloud DNS geolocation routing policy allows DNS responses to vary according to the geographic location associated with the DNS query. This can help direct users toward regionally appropriate endpoints or services. The policy is applied to DNS records rather than to VPC firewall processing or routing decisions. DNSSEC provides authenticity protection, forwarding policies control DNS forwarding behavior, and DNS peering connects DNS namespaces between networks. Geolocation routing is therefore useful when an organization wants DNS-based traffic distribution that considers the location of the requester. It can support regional service deployments and improve locality without requiring application-level routing logic.

Question 282

What identifies the VPC that contains a Shared VPC host configuration?

1. Host project
2. Consumer project
3. Service account
4. Backend project

Correct Answer: 1

Explanation:

In Shared VPC, the host project owns and administers the shared network resources. Service projects can attach workloads to eligible subnets provided by that host project. The host project therefore identifies the project where the Shared VPC network is configured and managed. A service project contains participating resources, while a service account represents an identity rather than a project-level network container. Backend projects are not a distinct Shared VPC role. Understanding the host-project relationship is important when assigning permissions because network administration and workload deployment responsibilities can be separated between host and service projects.

Question 283

Which Cloud Router capability determines the autonomous system number used for BGP?

1. Route priority
2. Advertisement mode
3. BGP session timer
4. Local ASN configuration

Correct Answer: 4

Explanation:

Cloud Router uses a configured autonomous system number, or ASN, for its BGP sessions. The ASN identifies the BGP autonomous system associated with the Cloud Router side of the peering relationship. Route priority determines which routes are preferred and does not define the autonomous system identity. Advertisement mode controls which routes Cloud Router advertises, while BGP session timers influence session behavior. Selecting the appropriate ASN is therefore part of establishing compatible BGP connectivity with a peer router. The peer’s ASN is configured separately, allowing each side of the BGP relationship to identify its own autonomous system.

Question 284

Which VPC firewall target mechanism applies rules to instances by network tag?

1. Subnet CIDR
2. Network tag
3. DNS name
4. Route destination

Correct Answer: 2

Explanation:

VPC firewall rules can target VM instances by using network tags. A tag assigned to an instance can be referenced by a firewall rule so that the rule applies to matching workloads. This provides a convenient way to group instances according to their intended network role without maintaining individual IP-address lists. Subnet CIDRs describe address ranges rather than instance tagging. DNS names are not the standard firewall target mechanism for selecting VM instances, and route destinations determine where traffic should be sent. Network tags are particularly useful when groups of workloads share a common security requirement.

Question 285

What does a Cloud DNS outbound forwarding policy primarily control?

1. Where selected DNS queries are forwarded
2. How VPC routes are prioritized
3. Which firewall rules allow DNS traffic
4. How DNSSEC signatures are generated

Correct Answer: 1

Explanation:

A Cloud DNS outbound forwarding policy controls forwarding of DNS queries from Google Cloud toward configured external DNS targets. This is useful when workloads need to resolve names hosted outside Cloud DNS, such as internal corporate domains maintained by an on-premises DNS infrastructure. Route priorities and firewall rules remain separate networking controls. DNSSEC signing is concerned with DNS authenticity rather than query forwarding. Outbound forwarding therefore provides a controlled DNS resolution path for selected queries while allowing Cloud DNS to continue serving zones and records that it manages directly.

Question 286

Which load-balancing component contains the configuration for backend endpoints and traffic distribution?

1. Forwarding rule
2. Health check
3. Backend service
4. DNS record

Correct Answer: 3

Explanation:

A backend service defines important characteristics of how a load balancer communicates with and distributes traffic among its backends. It can reference backend resources, health checks, balancing settings, and related traffic-management configuration. A forwarding rule determines how traffic reaches the load balancer frontend, while a health check determines whether backends are considered healthy. DNS records can direct clients toward an address or hostname but do not configure backend distribution. The backend service is therefore a central component when designing and troubleshooting Google Cloud load-balancing architectures.

Question 287

What is the primary purpose of VPC Flow Logs?

1. Encrypting packet payloads
2. Recording metadata about network flows
3. Blocking unauthorized connections
4. Translating private addresses

Correct Answer: 2

Explanation:

VPC Flow Logs provide metadata about network traffic flowing to and from resources associated with a subnet. They can help administrators investigate connectivity, understand traffic patterns, identify unexpected communication, and support security analysis. Flow Logs do not encrypt packet contents, enforce firewall decisions, or perform address translation. Those responsibilities belong to other networking mechanisms. Because Flow Logs capture traffic metadata rather than packet payloads, they can provide useful visibility without functioning as a packet capture system. Administrators can use the resulting logs with monitoring and analysis tools to investigate network behavior.

Question 288

Which Google Cloud service provides managed protection against volumetric and application-layer attacks on supported load-balanced applications?

1. Cloud DNS
2. Cloud Router
3. Cloud NAT
4. Cloud Armor

Correct Answer: 4

Explanation:

Cloud Armor provides security policies that can protect supported Google Cloud applications from unwanted traffic and various attack patterns. It can be integrated with Google Cloud load-balancing architectures and supports controls for filtering requests before they reach protected backends. Cloud DNS provides name resolution, Cloud Router handles dynamic routing, and Cloud NAT provides outbound address translation. Cloud Armor therefore occupies the application and edge-security role rather than a routing or DNS role. Its policies can help organizations enforce traffic controls consistently across protected services.

Question 289

Which VPC capability allows a workload to use multiple IP ranges on one network interface?

1. Cloud NAT
2. Alias IP ranges
3. Cloud VPN
4. Cloud CDN

Correct Answer: 2

Explanation:

Alias IP ranges allow a VM network interface to be associated with additional internal IP ranges beyond its primary interface address. This capability is useful for applications such as containerized workloads that need multiple addresses while remaining associated with the same underlying VM interface. Cloud NAT translates addresses for outbound connectivity, Cloud VPN provides encrypted connectivity between networks, and Cloud CDN accelerates content delivery. Alias IP ranges are therefore an important addressing mechanism when workloads require additional internal addresses without adding separate network interfaces.

Question 290

What does Private Google Access allow eligible resources to do?

1. Reach Google APIs and services without external IP addresses
2. Establish arbitrary BGP sessions with Google services
3. Advertise subnet routes to the public internet
4. Receive public DNS zones automatically

Correct Answer: 1

Explanation:

Private Google Access allows eligible resources without external IP addresses to reach supported Google APIs and services through Google’s network. This is useful when workloads should remain privately addressed while still accessing required Google-managed services. It does not automatically establish BGP sessions, advertise private subnet routes to the internet, or create public DNS zones. The feature is configured at the subnet level and is commonly used in architectures where VM instances do not need general public internet exposure but still require access to Google Cloud services.

Question 291

Which Network Connectivity Center component acts as the central connectivity hub?

1. VLAN attachment
2. VPN tunnel
3. Hub
4. DNS zone

Correct Answer: 4

Explanation:

Network Connectivity Center uses a hub as the central resource through which supported network connectivity can be organized. Spokes attach supported resources or networks to the hub, allowing connectivity to be managed through a centralized architecture. A VLAN attachment provides Interconnect connectivity, a VPN tunnel provides encrypted network connectivity, and a DNS zone handles name resolution. The hub is therefore the central organizational component of Network Connectivity Center. This model can simplify management when multiple networks and hybrid connectivity resources need to participate in a broader connectivity design.

Question 292

Which Cloud CDN setting influences which request characteristics determine cache entries?

1. BGP configuration
2. Cache key policy
3. Firewall priority
4. NAT allocation

Correct Answer: 3

Explanation:

A cache key policy determines which request attributes are considered when Cloud CDN identifies cached objects. Cache-key behavior can affect whether requests are treated as equivalent for caching purposes and therefore can influence cache efficiency. BGP configuration belongs to dynamic routing, firewall priority affects rule evaluation, and NAT allocation concerns address translation capacity. Cache key configuration is consequently an important consideration when optimizing content delivery behavior. Poorly designed cache-key characteristics can create unnecessary cache fragmentation, while an appropriate policy can improve reuse of cached content across suitable requests.

Question 293

What does a VPC peering connection primarily provide?

1. Private connectivity between two VPC networks
2. Public internet access between projects
3. Automatic DNSSEC signing
4. Shared firewall administration

Correct Answer: 1

Explanation:

VPC Network Peering provides private connectivity between separate VPC networks using Google’s internal network. The networks remain administratively separate while selected routes can be exchanged according to peering capabilities and configuration. VPC peering does not turn the networks into a single administrative domain, automatically provide public internet connectivity, or create centralized firewall administration. DNSSEC is unrelated to the basic purpose of peering. This model is useful when independently managed networks need private communication while retaining separate project and network administration boundaries.

Question 294

Which address type is designed to remain assigned to a resource rather than changing dynamically?

1. Ephemeral internal address
2. Temporary NAT port
3. Static IP address
4. Learned BGP route

Correct Answer: 4

Explanation:

A static IP address is reserved so that its value can remain associated with a resource instead of being automatically replaced when the resource lifecycle changes. This can be important for services whose clients, DNS records, or access-control configurations depend on a stable address. Ephemeral addresses can change when resources are stopped or recreated. NAT ports are transport-level translation resources rather than IP addresses, and a learned BGP route describes network reachability rather than an assigned address. Static addresses are therefore useful whenever predictable addressing is an architectural requirement.

Question 295

Which Google Cloud mechanism can connect a service consumer privately to a published producer service?

1. Cloud NAT
2. Private Service Connect
3. Cloud CDN
4. Cloud DNSSEC

Correct Answer: 2

Explanation:

Private Service Connect enables private consumption of supported services across service boundaries without requiring the consumer to expose traffic through the public internet. A producer publishes a service through an appropriate service attachment, while a consumer creates the corresponding private connectivity resource. Cloud NAT is designed for outbound address translation, Cloud CDN handles content caching, and DNSSEC protects DNS data integrity. Private Service Connect is therefore the service-oriented connectivity mechanism when a consumer needs private access to a published producer service while maintaining network isolation and controlled service exposure.

Question 296

Which protocol is used by Cloud Router to exchange dynamic routes with a peer?

1. ICMP
2. HTTPS
3. BGP
4. DNS

Correct Answer: 3

Explanation:

Cloud Router uses Border Gateway Protocol, or BGP, to exchange dynamic routing information with configured peers. BGP allows the Google Cloud environment and an external or supported networking peer to advertise and learn routes dynamically. ICMP is commonly used for diagnostic reachability testing, HTTPS provides secure application communication, and DNS resolves names to addresses. BGP is therefore the protocol relevant to Cloud Router’s dynamic route exchange function. Correct BGP configuration is essential for hybrid connectivity scenarios involving Cloud VPN or Cloud Interconnect.

Question 297

Which resource determines how incoming traffic reaches a Google Cloud load balancer frontend?

1. Forwarding rule
2. Backend instance
3. Cloud NAT gateway
4. DNSSEC key

Correct Answer: 4

Explanation:

A forwarding rule defines how traffic is directed to a load balancer’s frontend by specifying information such as the relevant IP address, protocol, and port configuration. It serves as an entry point for traffic arriving at the load-balancing architecture. Backend instances process traffic after the load balancer selects an appropriate backend. Cloud NAT handles outbound address translation, while DNSSEC keys are related to DNS authentication. The forwarding rule therefore plays a fundamental role in determining how incoming connections are accepted and mapped into the load-balancing system.

Question 298

What is the main benefit of using custom-mode VPC subnet creation?

1. Every region receives automatic subnet ranges
2. Administrators explicitly control subnet ranges
3. Google automatically selects all CIDRs
4. Subnets become globally routable public networks

Correct Answer: 1

Explanation:

Custom-mode VPC networks give administrators direct control over subnet creation and IP ranges. Instead of automatically creating regional subnets, administrators can design the addressing structure according to application requirements, organizational boundaries, growth expectations, and connectivity constraints. This makes custom mode particularly useful for carefully planned enterprise environments. Automatic subnet creation is associated with auto-mode behavior. Custom mode does not make subnets public or globally routable by itself. It simply provides greater control over the network’s regional subnet structure and associated address allocation strategy.

Question 299

Which Cloud VPN configuration provides multiple tunnels for higher availability?

1. Single static route
2. One DNS forwarding target
3. Multiple VPN tunnels
4. One firewall rule

Correct Answer: 3

Explanation:

Using multiple VPN tunnels can provide greater resilience than relying on a single tunnel. In highly available HA VPN designs, redundant tunnel configurations can maintain connectivity when an individual tunnel or path becomes unavailable. A static route describes forwarding behavior but does not itself provide tunnel redundancy. DNS forwarding targets concern name resolution, while firewall rules control traffic authorization. Multiple VPN tunnels therefore form an important part of resilient hybrid connectivity designs. The exact topology and routing configuration should also be planned so that traffic can use an available path when another path fails.

Question 300

Which Google Cloud feature provides centralized analysis of network connectivity paths?

1. Cloud NAT
2. Cloud DNS
3. Cloud Storage
4. Connectivity Tests

Correct Answer: 2

Explanation:

Network Intelligence Center Connectivity Tests can analyze connectivity between specified endpoints and identify configuration conditions that affect whether traffic can reach its destination. The analysis can help troubleshoot routing, firewall, forwarding, and related network-path issues. Cloud NAT focuses on outbound address translation, Cloud DNS handles name resolution, and Cloud Storage provides object storage rather than network-path analysis. Connectivity Tests are therefore useful when administrators need a structured way to investigate why traffic between two endpoints succeeds or fails within a Google Cloud networking environment.
