Google Professional Cloud Network Engineer exam dumps: questions 701 to 789 of 789

Correct answer: B

• A. Incorrect.

  Cloud VPN with IPsec tunnels provides encryption and secure connectivity, but it may not provide the low latency and high throughput required for transferring large volumes of data.

• B. Correct.

  Cloud Interconnect (Dedicated Interconnect or Partner Interconnect) establishes a direct, private connection between your on-premises network and Google Cloud, ensuring low latency, high security, and the ability to handle large data transfers.

• C. Incorrect.

  Transferring data over the public internet using HTTPS is secure but does not guarantee low latency or high throughput, making it unsuitable for large-scale data transfers.

• D. Incorrect.

  Cloud CDN is designed for caching and delivering content to end users. It is not suitable for transferring data between on-premises networks and a VPC.

Correct answer: A

• A. Correct.

  This is the correct choice. Cloud VPN with dynamic routing enabled via BGP provides encrypted communication, supports dynamic routing, and avoids public internet exposure, fulfilling all requirements.

• B. Incorrect.

  While Cloud Interconnect provides direct connectivity and avoids public internet, it does not inherently provide encryption. Additional mechanisms would be necessary to encrypt the data transfer.

• C. Incorrect.

  Cloud NAT is used for enabling private instances to access the internet securely, but it does not establish secure, site-to-site communication or support encryption for such transfers.

• D. Incorrect.

  Cloud CDN is designed to cache and deliver web content to users and is not suitable for secure site-to-site data transfers.

Correct answer: A

• A. Correct.

  This is the correct option. Cloud VPN provides a secure IPsec tunnel to establish site-to-site connectivity, ensuring high throughput and encryption during transit.

• B. Incorrect.

  While Cloud Interconnect provides a dedicated private connection with high throughput, it does not inherently provide encryption. You would need to implement encryption separately, which adds complexity.

• C. Incorrect.

  Cloud NAT is used for outbound internet traffic from private Google Cloud resources, not for establishing site-to-site connections.

• D. Incorrect.

  Using a public HTTP endpoint with HTTPS provides encryption, but it is not suitable for site-to-site data transfer as it lacks the necessary dedicated, secure tunnel for such use cases.

Correct answer: A

• A. Correct.

  This is the correct option. Cloud VPN (High Availability) supports encryption for data in transit, dynamic routing through BGP, and provides a reliable solution for site-to-site connectivity.

• B. Incorrect.

  While Dedicated Interconnect provides low latency and high bandwidth, it does not inherently provide encryption for data in transit. You would need to implement encryption at the application layer.

• C. Incorrect.

  Cloud VPN (Classic) supports static routing but does not meet the requirement for dynamic routing using BGP. Additionally, it is considered less reliable compared to the High Availability option.

• D. Incorrect.

  Partner Interconnect provides a connection via a service provider, but it does not provide encryption for data in transit. You would need to handle encryption separately, which may not meet the organization's requirements.

Correct answers: A, C

• A. Correct.

  Correct: A Cloud Router is required for each VPC to enable dynamic route exchange via BGP with the Router Appliance.

• B. Incorrect.

  Incorrect: Router Appliances are typically deployed in a specific VPC, not necessarily in a shared VPC subnet unless explicitly required by the architecture.

• C. Correct.

  Correct: BGP is essential for dynamic route exchange between the Router Appliance and the on-premises router.

• D. Incorrect.

  Incorrect: Enabling Private Google Access is not mandatory for deploying Router Appliances. It is used for accessing Google APIs and services privately.

• E. Incorrect.

  Incorrect: IAM permissions are not directly set up for Router Appliances to manage routes. Route management is handled by Cloud Router and attached BGP sessions.
