Question 341

Which Google Cloud service provides managed private connectivity to Google APIs?

1. Cloud NAT
2. Private Service Connect
3. Cloud Router
4. Cloud Armor

Correct Answer: 2

Explanation:

Private Service Connect can provide private connectivity to supported Google APIs and services from VPC environments. It allows applications to access services through internal networking rather than requiring direct public internet paths. This approach can help organizations maintain stronger network boundaries while consuming managed Google services. Cloud NAT serves outbound address translation, Cloud Router handles dynamic routing, and Cloud Armor provides traffic protection. Therefore, Private Service Connect is the appropriate service when the requirement is private access to supported Google APIs and services.

Question 342

Which VPN option is designed for high availability using multiple tunnels?

1. Classic VPN
2. Static VPN
3. HA VPN
4. External VPN

Correct Answer: 3

Explanation:

HA VPN is designed to provide highly available IPsec connectivity between Google Cloud and peer networks. It uses VPN tunnels and gateway interfaces in configurations that support redundancy and dynamic routing. Organizations commonly use HA VPN when they need resilient hybrid connectivity between VPC networks and on-premises environments. Classic VPN provides a different and older connectivity model, while the other listed choices do not represent the Google Cloud HA VPN service. Therefore, HA VPN is the appropriate option when availability and redundant tunnel configurations are important requirements.

Question 343

What does a VPC firewall rule primarily control?

1. Whether network traffic is allowed or denied
2. How DNS records are resolved
3. Which route has the shortest path
4. How NAT addresses are allocated

Correct Answer: 1

Explanation:

VPC firewall rules control whether network traffic is allowed or denied for applicable resources. Rules can evaluate characteristics such as direction, protocol, ports, sources, destinations, and targets. This provides an important layer of traffic control within a Google Cloud network. Firewall rules do not determine DNS resolution, route selection, or NAT address allocation. Those functions belong to other networking components. When designing a secure VPC, firewall rules should be configured according to the required communication paths while avoiding unnecessary access. Therefore, controlling permitted and denied traffic is the primary purpose of VPC firewall rules.

Question 344

Which resource is required to establish a BGP session for Cloud VPN connectivity?

1. Cloud DNS zone
2. Cloud Router
3. Cloud CDN service
4. Cloud Armor policy

Correct Answer: 2

Explanation:

Cloud Router provides the BGP functionality required for dynamic route exchange with supported Cloud VPN configurations. The router establishes BGP sessions with the peer network and exchanges prefixes so that routing information can be learned dynamically. This avoids relying exclusively on manually configured static routes for hybrid connectivity. Cloud DNS zones provide name resolution, Cloud CDN handles content delivery, and Cloud Armor provides security policies. Therefore, Cloud Router is the required Google Cloud resource when BGP-based dynamic routing is used with supported Cloud VPN architectures.

Question 345

Which feature can connect two VPC networks privately without using public IP addresses?

1. Cloud NAT
2. Cloud CDN
3. VPC Network Peering
4. Cloud DNS

Correct Answer: 3

Explanation:

VPC Network Peering provides private connectivity between separate VPC networks using Google’s internal network. Once peering is configured correctly, supported subnet routes can be exchanged so resources can communicate using internal IP addresses. The two VPC networks remain separate administrative entities, which means peering does not combine them into a single VPC. Cloud NAT focuses on outbound translation, Cloud CDN distributes content, and Cloud DNS provides name-resolution capabilities. Therefore, VPC Network Peering is the feature intended for private communication between separate VPC networks.

Question 346

Which Google Cloud service can cache content closer to users?

1. Cloud Router
2. Cloud CDN
3. Cloud NAT
4. Cloud VPN

Correct Answer: 2

Explanation:

Cloud CDN uses Google’s distributed edge infrastructure to cache eligible content closer to users. By serving cached responses from locations closer to clients, it can reduce latency and decrease repeated requests to origin infrastructure. Cloud CDN is commonly integrated with supported load-balancing architectures for applications that serve cacheable content. Cloud Router manages dynamic routes, Cloud NAT performs address translation, and Cloud VPN provides encrypted network connectivity. Therefore, Cloud CDN is the Google Cloud service designed specifically to improve content delivery through distributed caching.

Question 347

Which IP address type identifies a VM within a VPC network?

1. Internal IP address
2. External DNS address
3. Public gateway address
4. NAT pool identifier

Correct Answer: 1

Explanation:

An internal IP address identifies a VM within its VPC network and is assigned from the applicable subnet range. Internal addresses are used for communication between resources that have appropriate network connectivity. A VM can also have an external IP address when public connectivity is required, but that address serves a different purpose. DNS names and NAT configurations do not themselves identify a VM’s internal network interface. Therefore, the internal IP address is the fundamental address used to identify and communicate with a VM within its VPC environment.

Question 348

Which load-balancing capability routes requests according to URL paths?

1. Cloud NAT
2. BGP routing
3. Path-based routing
4. DNS forwarding

Correct Answer: 3

Explanation:

Path-based routing allows an HTTP or HTTPS load balancer to direct requests to different backend services according to URL paths. For example, requests targeting one application path can be sent to one backend while another path is handled by a different backend. This capability is typically configured through URL maps and related load-balancing resources. Cloud NAT handles address translation, BGP exchanges network routes, and DNS forwarding handles name-resolution requests. Therefore, path-based routing is the capability specifically designed to distribute application requests according to URL paths.

Question 349

Which resource provides a private IP range for resources in a region?

1. VPC network
2. Cloud Router
3. VPC subnet
4. Cloud VPN gateway

Correct Answer: 3

Explanation:

A VPC subnet provides IP address ranges that resources in the corresponding region can use for internal addressing. Although the VPC network itself is global, each subnet is associated with a particular region. Subnets therefore form the regional IP addressing structure within a VPC. Cloud Router manages dynamic routing, and Cloud VPN gateways support encrypted connectivity with peer networks. Understanding the relationship between global VPC networks and regional subnets is essential when planning address allocation and resource placement. Thus, the VPC subnet is the resource that provides the regional IP range.

Question 350

Which technology is appropriate when a company requires high-bandwidth private connectivity to Google Cloud?

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

Correct Answer: 2

Explanation:

Cloud Interconnect is designed to provide private connectivity between an external network and Google Cloud. Dedicated Interconnect and Partner Interconnect can support organizations with substantial data-transfer requirements and hybrid network architectures. Because the connectivity does not rely on ordinary public internet paths, it can be integrated into enterprise network designs that require private access to Google Cloud resources. Cloud DNS handles name resolution, Cloud NAT provides outbound translation, and Cloud Armor supplies security controls. Therefore, Cloud Interconnect is the appropriate networking technology for high-bandwidth private connectivity requirements.

Question 351

Which routing protocol does Google Cloud use for dynamic hybrid route exchange?

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

Correct Answer: 1

Explanation:

Border Gateway Protocol is used by Cloud Router for dynamic route exchange with supported external networks. BGP allows Google Cloud and connected peer networks to advertise and learn IP prefixes dynamically. This is particularly useful for hybrid architectures involving HA VPN and Cloud Interconnect. Dynamic exchange means route changes can be propagated without manually updating every route on both sides. OSPF, RIP, and IS-IS are different routing protocols and are not the standard protocol used by Cloud Router for these supported hybrid connectivity scenarios. Therefore, BGP is the correct answer.

Question 352

What does Private Google Access primarily avoid for eligible VM instances?

1. Internal DNS resolution
2. The need for external IP addresses
3. Subnet configuration
4. Firewall evaluation

Correct Answer: 2

Explanation:

Private Google Access allows eligible resources without external IP addresses to access supported Google APIs and services. This means a VM does not need a public external IP address merely to communicate with supported Google services. The feature is especially useful for workloads designed to remain private while still consuming Google-managed services. Private Google Access does not eliminate the need for subnets or firewall controls, and it does not simply replace internal DNS functionality. Therefore, its key benefit is enabling access to supported Google services without assigning external IP addresses to the participating resources.

Question 353

Which component can distribute traffic across multiple backend instances?

1. Cloud DNS
2. Cloud Router
3. Load balancer
4. Cloud NAT

Correct Answer: 3

Explanation:

A load balancer distributes incoming traffic across multiple backend resources according to the configuration and traffic type. Google Cloud provides several load-balancing options for application, proxy, and passthrough use cases. Load balancing can improve availability and help distribute workload demand across backend instances or other supported resources. Cloud DNS provides name resolution, Cloud Router exchanges routes, and Cloud NAT performs outbound address translation. Therefore, the load balancer is the networking component responsible for distributing traffic among backend resources.

Question 354

Which Google Cloud service performs network address translation for outbound traffic?

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

Correct Answer: 3

Explanation:

Cloud NAT performs network address translation for outbound connections from supported resources that do not have external IP addresses. It allows private workloads to initiate connections to external destinations while keeping their individual internal addresses private. Cloud NAT is commonly used for software updates, external API calls, and other outbound requirements. Cloud Armor handles security policies, Cloud DNS provides DNS services, and Cloud Router exchanges dynamic routes. Therefore, Cloud NAT is the service responsible for translating private source addresses for supported outbound traffic.

Question 355

Which feature provides centralized firewall policies across multiple Google Cloud resources?

1. Hierarchical firewall policies
2. Cloud CDN
3. Cloud NAT
4. Cloud DNS

Correct Answer: 1

Explanation:

Hierarchical firewall policies allow organizations to apply firewall controls at higher levels of the Google Cloud resource hierarchy. Policies can be associated with organizations or folders and can affect resources beneath those hierarchy levels. This provides centralized control compared with configuring every individual VPC independently. Cloud CDN is used for content delivery, Cloud NAT provides address translation, and Cloud DNS manages DNS services. Hierarchical firewall policies are therefore useful when security requirements need to be applied consistently across multiple projects or VPC environments.

Question 356

Which Google Cloud option provides encrypted connectivity over the public internet?

1. Cloud Interconnect
2. Cloud VPN
3. Cloud CDN
4. Private Google Access

Correct Answer: 2

Explanation:

Cloud VPN provides encrypted connectivity between Google Cloud and peer networks through IPsec tunnels. It is useful when an organization needs secure hybrid connectivity but does not require dedicated physical connectivity. HA VPN can provide highly available configurations for supported architectures. Cloud Interconnect uses private connectivity rather than ordinary public internet VPN tunnels, Cloud CDN handles content caching, and Private Google Access provides access to supported Google APIs from eligible resources. Therefore, Cloud VPN is the appropriate option for encrypted connectivity over the public internet.

Question 357

Which VPC property determines whether dynamic routes are available across regions?

1. DNS policy
2. Firewall priority
3. Dynamic routing mode
4. NAT configuration

Correct Answer: 3

Explanation:

The VPC’s dynamic routing mode determines the scope at which dynamically learned routes from Cloud Router are available. Regional dynamic routing limits learned routes to the region containing the Cloud Router, while global dynamic routing can make those learned routes available across regions in the VPC. This distinction is important in hybrid environments where resources may exist in multiple Google Cloud regions. DNS policies, firewall priorities, and NAT configurations serve different networking functions. Therefore, dynamic routing mode is the VPC property that determines the regional scope of dynamically learned routes.

Question 358

Which service can enforce security policies on supported load-balanced applications?

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

Correct Answer: 1

Explanation:

Cloud Armor provides security policies for supported Google Cloud load-balancing architectures. These policies can help control unwanted traffic and provide protections for internet-facing applications. Administrators can define rules that evaluate characteristics of incoming requests and apply appropriate actions based on the configured policy. Cloud Router manages dynamic routing, Cloud DNS provides name resolution, and Cloud NAT handles outbound translation. Therefore, Cloud Armor is the service associated with applying security policies to supported load-balanced applications.

Question 359

Which connectivity model lets a service producer expose a service privately to consumers?

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

Correct Answer: 3

Explanation:

Private Service Connect allows service producers to publish supported services privately so that consumers can connect through private network endpoints. This model helps separate service consumers from producer network details while keeping service traffic on Google’s network. It can be useful for organizations that need private access to services without exposing them through traditional public endpoints. Cloud CDN focuses on caching, Cloud NAT handles outbound translation, and Cloud Router manages dynamic route exchange. Therefore, Private Service Connect is the appropriate connectivity model for privately published services.

Question 360

Which resource contains the IP range from which VM internal addresses are assigned?

1. Cloud Router
2. VPC subnet
3. Cloud VPN gateway
4. Load balancer

Correct Answer: 2

Explanation:

A VPC subnet contains the primary IP range from which VM instances and other supported resources can receive internal IP addresses. Subnets are regional resources within a global VPC network, allowing organizations to organize address space by region. Secondary ranges can also be configured for supported workloads such as Google Kubernetes Engine. Cloud Router manages dynamic route exchange, Cloud VPN gateways support encrypted connectivity, and load balancers distribute traffic. Therefore, the VPC subnet is the resource that contains the IP range used for internal VM addressing.
