Question 101<\/b><\/h3>\n

Which Google Cloud feature can assign multiple internal addresses to a single VM interface?<\/b><\/p>\n

    \n
  1. Cloud DNS forwarding<\/span><\/li>\n
  2. Cloud Armor policy<\/span><\/li>\n
  3. VPC route<\/span><\/li>\n
  4. Alias IP range<\/span><\/li>\n<\/ol>\n

    Correct Answer: 4<\/b><\/p>\n

    Explanation:<\/b><\/p>\n

    Alias IP ranges allow additional internal IP addresses or ranges to be associated with a VM network interface. This capability is useful for workloads that need multiple network identities without requiring a separate network interface for each address. It is commonly relevant to containerized and other specialized workload architectures. Cloud DNS forwarding handles name resolution, Cloud Armor provides security policies, and VPC routes determine packet forwarding. Alias IP ranges therefore address workload-level network addressing rather than routing, DNS, or application security functions.<\/span><\/p>\n

    Question 102<\/b><\/h3>\n

    Which routing mode can make dynamically learned routes available across VPC regions?<\/b><\/p>\n

      \n
    1. Regional dynamic routing<\/span><\/li>\n
    2. Global dynamic routing<\/span><\/li>\n
    3. Static routing<\/span><\/li>\n
    4. Local-only routing<\/span><\/li>\n<\/ol>\n

      Correct Answer: 2<\/b><\/p>\n

      Explanation:<\/b><\/p>\n

      Global dynamic routing allows routes learned through Cloud Router to be available across regions within the VPC, subject to the applicable routing behavior and configuration. This can simplify hybrid connectivity when external networks need to reach workloads located in multiple Google Cloud regions. Regional dynamic routing limits the scope of dynamically learned routes to the relevant region. Static routing relies on manually configured entries rather than dynamic BGP exchange. Selecting the appropriate mode depends on the desired geographic scope of hybrid route propagation.<\/span><\/p>\n

      Question 103<\/b><\/h3>\n

      Which component is responsible for checking whether a backend responds on a configured port?<\/b><\/p>\n

        \n
      1. Forwarding rule<\/span><\/li>\n
      2. Health check<\/span><\/li>\n
      3. DNS zone<\/span><\/li>\n
      4. Route table<\/span><\/li>\n<\/ol>\n

        Correct Answer: 3<\/b><\/p>\n

        Explanation:<\/b><\/p>\n

        A load-balancer health check can test whether a backend responds according to configured health-check criteria, including the relevant protocol and port. The resulting health information helps the load balancer determine whether the backend should receive traffic. A forwarding rule defines how traffic reaches a frontend, a DNS zone manages name records, and route tables determine packet forwarding. Health checks therefore provide operational information about backend availability. Proper health-check configuration is important because an incorrectly configured check can cause healthy resources to be treated as unavailable.<\/span><\/p>\n

        Question 104<\/b><\/h3>\n

        Which Google Cloud service is designed to distribute application requests across healthy backends?<\/b><\/p>\n

          \n
        1. Cloud Load Balancing<\/span><\/li>\n
        2. Cloud DNS<\/span><\/li>\n
        3. Cloud NAT<\/span><\/li>\n
        4. Cloud Router<\/span><\/li>\n<\/ol>\n

          Correct Answer: 1<\/b><\/p>\n

          Explanation:<\/b><\/p>\n

          Cloud Load Balancing distributes incoming traffic across eligible backend resources according to the selected load-balancing architecture and configuration. Health information can influence which backends receive traffic, helping applications maintain availability when individual resources become unhealthy. Different load balancers support different protocols, traffic sources, and application architectures. Cloud DNS provides name resolution, Cloud NAT provides outbound address translation, and Cloud Router exchanges dynamic routes. Cloud Load Balancing is therefore the service responsible for directing client or network traffic across suitable backend resources.<\/span><\/p>\n

          Question 105<\/b><\/h3>\n

          What does an internal load balancer frontend normally provide?<\/b><\/p>\n

            \n
          1. A private entry point for internal clients<\/span><\/li>\n
          2. A BGP peer identity<\/span><\/li>\n
          3. A DNS zone transfer server<\/span><\/li>\n
          4. A NAT allocation pool<\/span><\/li>\n<\/ol>\n

            Correct Answer: 2<\/b><\/p>\n

            Explanation:<\/b><\/p>\n

            An internal load balancer frontend provides a private network entry point for clients that need to access an application or service without exposing the frontend directly to the public internet. The frontend can use an internal IP address within the appropriate VPC architecture. BGP peer identities belong to routing configurations, DNS zone transfers relate to name resolution, and NAT allocation concerns address translation. Internal load balancing is particularly useful for multi-tier applications where frontend clients or application components need controlled private access to backend services.<\/span><\/p>\n

            Question 106<\/b><\/h3>\n

            Which Google Cloud service can establish encrypted tunnels for hybrid network connectivity?<\/b><\/p>\n

              \n
            1. Cloud Interconnect<\/span><\/li>\n
            2. Cloud DNS<\/span><\/li>\n
            3. Cloud VPN<\/span><\/li>\n
            4. Cloud CDN<\/span><\/li>\n<\/ol>\n

              Correct Answer: 4<\/b><\/p>\n

              Explanation:<\/b><\/p>\n

              Cloud VPN establishes encrypted tunnels between supported network environments. It is commonly used for hybrid connectivity when organizations need secure communication between Google Cloud and external networks over an IP-based transport. HA VPN provides a highly available VPN architecture when configured appropriately. Cloud Interconnect provides private connectivity but is not itself an encrypted VPN tunnel service. Cloud DNS manages name resolution, while Cloud CDN handles content delivery. Cloud VPN is therefore the networking service most directly associated with encrypted tunnel-based connectivity.<\/span><\/p>\n

              Question 107<\/b><\/h3>\n

              Which service provides centralized visibility into Google Cloud network topology?<\/b><\/p>\n

                \n
              1. Network Intelligence Center<\/span><\/li>\n
              2. Cloud NAT<\/span><\/li>\n
              3. Cloud DNS<\/span><\/li>\n
              4. Cloud Armor<\/span><\/li>\n<\/ol>\n

                Correct Answer: 1<\/b><\/p>\n

                Explanation:<\/b><\/p>\n

                Network Intelligence Center provides networking visibility and diagnostic capabilities across supported Google Cloud environments. Its features can help engineers understand network topology, test connectivity, analyze performance, and investigate configuration-related problems. This centralized visibility is valuable in environments containing many VPCs, workloads, load balancers, and hybrid connections. Cloud NAT, Cloud DNS, and Cloud Armor each provide specific networking functions rather than a broad network-analysis platform. Network Intelligence Center therefore serves as an important operational tool for understanding and troubleshooting complex Google Cloud network architectures.<\/span><\/p>\n

                Question 108<\/b><\/h3>\n

                Which DNS capability forwards queries to resolvers outside the local Cloud DNS environment?<\/b><\/p>\n

                  \n
                1. Private zone attachment<\/span><\/li>\n
                2. DNS forwarding<\/span><\/li>\n
                3. DNSSEC validation<\/span><\/li>\n
                4. Record-set import<\/span><\/li>\n<\/ol>\n

                  Correct Answer: 3<\/b><\/p>\n

                  Explanation:<\/b><\/p>\n

                  DNS forwarding allows matching DNS queries to be sent to designated DNS resolvers outside the local Cloud DNS resolution environment. This is particularly useful in hybrid architectures where Google Cloud workloads must resolve names maintained by on-premises or other external DNS systems. Private zones provide internally managed DNS records, while DNSSEC relates to DNS security and validation. Record-set management is a separate function. DNS forwarding therefore provides a mechanism for integrating Google Cloud DNS resolution with another DNS infrastructure.<\/span><\/p>\n

                  Question 109<\/b><\/h3>\n

                  Which networking capability can keep supported workloads privately addressed while accessing Google APIs?<\/b><\/p>\n

                    \n
                  1. Cloud CDN<\/span><\/li>\n
                  2. Private Google Access<\/span><\/li>\n
                  3. Cloud Armor<\/span><\/li>\n
                  4. Cloud Router<\/span><\/li>\n<\/ol>\n

                    Correct Answer: 4<\/b><\/p>\n

                    Explanation:<\/b><\/p>\n

                    Private Google Access enables eligible resources without external IP addresses to access supported Google APIs and services. This allows workloads to retain private network addressing while still communicating with required managed Google services. The capability is configured in the relevant subnet and depends on supported workload and service conditions. Cloud CDN handles content caching, Cloud Armor provides security policies, and Cloud Router manages dynamic routing. Private Google Access is therefore useful when organizations want to minimize external IP exposure while maintaining access to supported Google services.<\/span><\/p>\n

                    Question 110<\/b><\/h3>\n

                    Which service provides private connectivity between a consumer and a published service?<\/b><\/p>\n

                      \n
                    1. Cloud Router<\/span><\/li>\n
                    2. Cloud NAT<\/span><\/li>\n
                    3. Private Service Connect<\/span><\/li>\n
                    4. Cloud DNS<\/span><\/li>\n<\/ol>\n

                      Correct Answer: 2<\/b><\/p>\n

                      Explanation:<\/b><\/p>\n

                      Private Service Connect provides a private connectivity model for accessing supported published services. A consumer can use a private endpoint to reach a service while maintaining separation between the consumer network and the service producer’s underlying infrastructure. This architecture is useful for managed services and service-oriented applications where public exposure is undesirable. Cloud Router handles dynamic routing, Cloud NAT provides address translation, and Cloud DNS manages name resolution. Private Service Connect therefore focuses on controlled private service consumption rather than general-purpose routing or DNS operations.<\/span><\/p>\n

                      Question 111<\/b><\/h3>\n

                      Which Google Cloud service can protect supported applications from unwanted web traffic?<\/b><\/p>\n

                        \n
                      1. Cloud Armor<\/span><\/li>\n
                      2. Cloud DNS<\/span><\/li>\n
                      3. Cloud Router<\/span><\/li>\n
                      4. Cloud NAT<\/span><\/li>\n<\/ol>\n

                        Correct Answer: 3<\/b><\/p>\n

                        Explanation:<\/b><\/p>\n

                        Cloud Armor provides security policies that can control and filter traffic directed toward supported applications and load-balancing architectures. These policies can help protect applications from unwanted requests and various web-based threats. Cloud Armor can complement other security mechanisms such as identity controls, VPC firewall policies, application protections, and monitoring. Cloud DNS provides name resolution, Cloud Router exchanges routes, and Cloud NAT performs outbound translation. Cloud Armor is therefore the service specifically designed for policy-based protection of supported application traffic at the network edge.<\/span><\/p>\n

                        Question 112<\/b><\/h3>\n

                        What is the main purpose of a Cloud Interconnect VLAN attachment?<\/b><\/p>\n

                          \n
                        1. To provide a logical connection for Interconnect traffic<\/span><\/li>\n
                        2. To store private DNS records<\/span><\/li>\n
                        3. To perform application-layer health checks<\/span><\/li>\n
                        4. To create firewall hierarchy<\/span><\/li>\n<\/ol>\n

                          Correct Answer: 1<\/b><\/p>\n

                          Explanation:<\/b><\/p>\n

                          A VLAN attachment represents a logical connection between a Google Cloud VPC network and an external network over Cloud Interconnect. It works with Cloud Router in configurations that use dynamic routing to exchange network information. The attachment is part of the Interconnect architecture that allows traffic to move between the external environment and the selected Google Cloud network. Private DNS records, application health checks, and firewall hierarchy are handled by other services. Understanding VLAN attachments is important when configuring private hybrid connectivity through Dedicated or Partner Interconnect.<\/span><\/p>\n

                          Question 113<\/b><\/h3>\n

                          Which network design principle separates workloads according to their communication requirements?<\/b><\/p>\n

                            \n
                          1. Network segmentation<\/span><\/li>\n
                          2. DNS delegation<\/span><\/li>\n
                          3. Route aggregation<\/span><\/li>\n
                          4. Packet sampling<\/span><\/li>\n<\/ol>\n

                            Correct Answer: 4<\/b><\/p>\n

                            Explanation:<\/b><\/p>\n

                            Network segmentation separates workloads into distinct communication boundaries based on application, security, organizational, or operational requirements. For example, development, production, and administrative workloads can be placed into appropriately controlled network environments. Firewall policies, VPC architecture, subnet design, and identity-based controls can support segmentation. DNS delegation addresses domain management, route aggregation concerns routing efficiency, and packet sampling relates to traffic observation. Segmentation is therefore a broader architectural approach used to reduce unnecessary connectivity and establish clearer security boundaries between workloads.<\/span><\/p>\n

                            Question 114<\/b><\/h3>\n

                            Which Google Cloud feature can provide centralized firewall controls across multiple projects?<\/b><\/p>\n

                              \n
                            1. Cloud CDN<\/span><\/li>\n
                            2. Hierarchical firewall policy<\/span><\/li>\n
                            3. Cloud DNS zone<\/span><\/li>\n
                            4. Cloud NAT gateway<\/span><\/li>\n<\/ol>\n

                              Correct Answer: 3<\/b><\/p>\n

                              Explanation:<\/b><\/p>\n

                              Hierarchical firewall policies can provide centralized network traffic controls at higher levels of the Google Cloud resource hierarchy. This allows organizations to establish security requirements that can apply consistently across multiple projects and network environments. Such policies can complement network-level firewall configurations and support organizational governance. Cloud CDN manages content delivery, Cloud DNS manages name resolution, and Cloud NAT provides outbound address translation. Hierarchical firewall policies are therefore appropriate when network security requirements need to be centrally managed across a broader resource hierarchy.<\/span><\/p>\n

                              Question 115<\/b><\/h3>\n

                              Which information is most useful when selecting subnet CIDR ranges?<\/b><\/p>\n

                                \n
                              1. Existing and planned network address requirements<\/span><\/li>\n
                              2. The browser version used by engineers<\/span><\/li>\n
                              3. The number of Cloud DNS zones<\/span><\/li>\n
                              4. The preferred load-balancer name<\/span><\/li>\n<\/ol>\n

                                Correct Answer: 1<\/b><\/p>\n

                                Explanation:<\/b><\/p>\n

                                Subnet CIDR ranges should be selected after considering existing and planned address requirements. Engineers should evaluate current workloads, expected growth, regional expansion, hybrid connections, peered networks, and potential future integrations. The selected range should also avoid conflicts with other networks that need to communicate with the subnet. Browser versions, DNS-zone counts, and resource naming conventions do not determine appropriate IP capacity. Careful CIDR planning provides enough address space for growth while reducing the risk of overlapping ranges and difficult network migrations later.<\/span><\/p>\n

                                Question 116<\/b><\/h3>\n

                                Which routing protocol is used by Cloud Router for dynamic route exchange?<\/b><\/p>\n

                                  \n
                                1. OSPF<\/span><\/li>\n
                                2. EIGRP<\/span><\/li>\n
                                3. BGP<\/span><\/li>\n
                                4. IS-IS<\/span><\/li>\n<\/ol>\n

                                  Correct Answer: 2<\/b><\/p>\n

                                  Explanation:<\/b><\/p>\n

                                  Cloud Router uses the Border Gateway Protocol, or BGP, for dynamic route exchange with supported external peers. BGP allows Google Cloud and connected networks to advertise and learn network prefixes dynamically. This is commonly used with HA VPN and Cloud Interconnect for hybrid connectivity. OSPF, EIGRP, and IS-IS are different routing protocols and are not the protocol Cloud Router uses for its supported dynamic routing sessions. Understanding BGP is therefore essential when designing hybrid Google Cloud networks that depend on Cloud Router.<\/span><\/p>\n

                                  Question 117<\/b><\/h3>\n

                                  Which service can cache eligible web content at Google’s edge locations?<\/b><\/p>\n

                                    \n
                                  1. Cloud Router<\/span><\/li>\n
                                  2. Cloud VPN<\/span><\/li>\n
                                  3. Cloud CDN<\/span><\/li>\n
                                  4. Cloud DNS<\/span><\/li>\n<\/ol>\n

                                    Correct Answer: 3<\/b><\/p>\n

                                    Explanation:<\/b><\/p>\n

                                    Cloud CDN caches eligible content at Google’s distributed edge locations. By serving cacheable content from an edge location closer to users, the service can reduce latency and decrease repeated requests reaching the origin backend. Cloud CDN is commonly useful for static or otherwise cacheable content that receives repeated requests. Cloud Router handles dynamic routing, Cloud VPN establishes encrypted connectivity, and Cloud DNS manages DNS resolution. Cloud CDN therefore focuses on improving content delivery efficiency rather than establishing network paths or managing network addresses.<\/span><\/p>\n

                                    Question 118<\/b><\/h3>\n

                                    Which capability helps determine why traffic cannot reach a destination in a VPC?<\/b><\/p>\n

                                      \n
                                    1. Network Topology<\/span><\/li>\n
                                    2. Connectivity Tests<\/span><\/li>\n
                                    3. Cloud CDN<\/span><\/li>\n
                                    4. Cloud DNS<\/span><\/li>\n<\/ol>\n

                                      Correct Answer: 4<\/b><\/p>\n

                                      Explanation:<\/b><\/p>\n

                                      Connectivity Tests can analyze network paths and configuration conditions that influence whether traffic can reach a selected destination. The analysis can consider relevant routes, firewall behavior, and other networking components. This makes the feature useful for troubleshooting connectivity failures without relying entirely on manual inspection. Network Topology provides broader visual network information, while Cloud CDN and Cloud DNS perform content-delivery and name-resolution functions. Connectivity Tests is therefore particularly suited to answering questions about why a specific network connection succeeds or fails.<\/span><\/p>\n

                                        Correct Answer: 1<\/b><\/p>\n

                                        Explanation:<\/b><\/p>\n

                                        Partner Interconnect provides private connectivity to Google Cloud through a supported service provider. It is useful for organizations that need Interconnect-style connectivity but prefer or require a provider-assisted connection model. Dedicated Interconnect uses a direct physical connection to Google’s network, while HA VPN uses encrypted tunnels over an IP-based transport. Cloud NAT is an address-translation service rather than a hybrid connectivity option. Partner Interconnect therefore fits architectures where a telecommunications or connectivity provider supplies the physical network path.<\/span><\/p>\n

                                          Correct Answer: 2<\/b><\/p>\n

                                          Explanation:<\/b><\/p>\n

                                          VPC Flow Logs provide traffic-flow metadata that can help reveal communication between workloads and network endpoints. Engineers can use this information to identify unexpected connections, investigate traffic patterns, support security analysis, and troubleshoot connectivity. Flow Logs do not capture complete application payloads, but they provide useful visibility into network-level communication. Cloud DNS records describe name-resolution activity, CDN metadata concerns cached content, and BGP authentication data relates to routing sessions. VPC Flow Logs are therefore particularly valuable when investigating which workloads are communicating across a network.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
