Which of the following design decisions would best meet these requirements?

  1. A

    Use Cloud Interconnect to establish a private connection between regions.

  2. B

    Configure a Shared VPC and use VPC Network Peering for communication between regions.

  3. C

    Implement a global external HTTP(S) Load Balancer with backends in multiple regions.

  4. D

    Enable Private Google Access for secure communication between services in different regions.

  5. E

    Use a single VPC with subnets in multiple regions and leverage Google Cloud's global network.

Show answer and explanation

Correct answers: C, E

Explanation

To meet the requirements of low latency, high availability, and secure connectivity for an inter-region application, the best design involves using Google Cloud's global infrastructure. A global external HTTP(S) Load Balancer ensures low-latency and highly available traffic distribution, while a single VPC with subnets across regions leverages Google's global network backbone for secure and efficient communication between regions.

  • A. Incorrect.

    Cloud Interconnect is used for private, high-bandwidth connections between on-premises networks and Google Cloud, not for inter-region communication within Google Cloud.

  • B. Incorrect.

    While VPC Network Peering can connect VPCs across regions, it is less efficient than leveraging Google Cloud's global network for inter-region communication within a single VPC.

  • C. Correct.

    A global external HTTP(S) Load Balancer provides low-latency, highly available, and secure communication by distributing traffic across multiple regions.

  • D. Incorrect.

    Private Google Access enables private communication to Google services from instances without public IPs but does not directly address inter-region communication requirements.

  • E. Correct.

    A single VPC with subnets in multiple regions allows you to use Google Cloud's global network backbone, ensuring low-latency and secure communication between regions.

Google Professional Cloud Network Engineer Question 2

Select 3Google Cloud Platform

You are designing the network architecture for a new application deployment on Google Cloud. The application requires a highly available and secure setup with low latency for global users. It also needs to integrate with an existing on-premises environment. Which considerations should you prioritize when designing the network architecture?

  1. A

    Set up a multi-region Virtual Private Cloud (VPC) with subnets in each region to reduce latency for global users.

  2. B

    Use Cloud VPN or Interconnect to establish secure connectivity to the on-premises environment.

  3. C

    Enable private Google access for the VPC to ensure secure and low-latency access to Google APIs and services.

  4. D

    Deploy a single-region VPC and rely on global load balancing to handle traffic from all regions.

  5. E

    Implement a firewall rule allowing all inbound traffic to improve application reachability.

Show answer and explanation

Correct answers: A, B, C

Explanation

To meet the requirements of a highly available, secure, and low-latency network architecture for global users and on-premises integration, you should design a multi-region VPC, establish secure connectivity using Cloud VPN or Interconnect, and enable private Google access for optimized performance and security. A single-region VPC or overly permissive firewall rules would not fulfill these requirements.

  • A. Correct.

    Correct: A multi-region VPC with subnets in each region ensures low latency for global users by placing resources closer to their physical locations.

  • B. Correct.

    Correct: Using Cloud VPN or Interconnect is essential for providing secure and reliable connectivity between the Google Cloud environment and the on-premises network.

  • C. Correct.

    Correct: Enabling private Google access allows resources in the VPC to securely communicate with Google APIs and services without traversing the public internet, reducing latency and enhancing security.

  • D. Incorrect.

    Incorrect: While global load balancing is useful, relying solely on a single-region VPC would not guarantee low latency for global users or meet the requirements for high availability.

  • E. Incorrect.

    Incorrect: Allowing all inbound traffic through a firewall rule is a security risk and does not align with best practices for secure and controlled network architecture.

Google Professional Cloud Network Engineer Question 3

Select 3Google Cloud Platform

You are tasked with designing a network architecture for a company that plans to run a hybrid cloud setup using Google Cloud and their on-premises data center. The company has strict compliance requirements to ensure that sensitive data never leaves their private on-premises network, while non-sensitive workloads can run in Google Cloud. Which of the following considerations are MOST important when designing the overall network architecture to meet these requirements?

  1. A

    Implementing a Dedicated Interconnect or VPN to establish connectivity between Google Cloud and the on-premises network

  2. B

    Using Google Cloud's Shared VPC to centrally manage network resources across multiple projects

  3. C

    Configuring private Google Access for on-premises workloads to securely access Google APIs without exposing them to the internet

  4. D

    Designing custom IAM roles to restrict access to sensitive data in Google Cloud

  5. E

    Setting up firewall rules to restrict traffic between on-premises and Google Cloud based on compliance requirements

Show answer and explanation

Correct answers: A, C, E

Explanation

Designing a hybrid cloud network architecture requires secure and efficient connectivity between on-premises and Google Cloud while adhering to compliance requirements. A Dedicated Interconnect or VPN ensures secure connectivity, private Google Access enables secure communication with Google APIs, and firewall rules provide control over traffic to enforce compliance. Shared VPC and IAM roles are valuable but do not directly address the specific compliance and connectivity needs of this scenario.

  • A. Correct.

    Correct: A Dedicated Interconnect or VPN is essential for securely connecting the on-premises network to Google Cloud and meeting the hybrid cloud requirements.

  • B. Incorrect.

    Incorrect: While Shared VPC is useful for centralizing network resource management, it does not specifically address the compliance requirement to keep sensitive data on-premises.

  • C. Correct.

    Correct: Private Google Access ensures on-premises workloads can securely access Google APIs without exposing them to the public internet, aligning with compliance and security requirements.

  • D. Incorrect.

    Incorrect: While IAM roles are important for access control, they do not address the need for network-level compliance or connectivity between on-premises and Google Cloud.

  • E. Correct.

    Correct: Firewall rules are critical for enforcing compliance requirements by restricting and controlling traffic flow between on-premises and Google Cloud.
