Google Professional Cloud Network Engineer Question 79
Select 3Google Cloud PlatformYou are designing a Google Cloud network for a multinational company that requires high availability and low latency between its global offices. The company also plans to migrate its on-premises applications to Google Cloud while retaining its existing IP address ranges to minimize disruption. Which of the following steps should you take to plan the IP address management strategy?
- A
Use Private Google Access to allow VMs to connect to Google APIs and services without assigning external IPs.
- B
Enable Bring Your Own IP (BYOIP) to migrate the existing IP ranges to Google Cloud.
- C
Plan the subnet ranges in each region to avoid overlaps with the on-premises IP ranges.
- D
Use IPv6 addressing to ensure scalability and accommodate future growth.
- E
Configure Public IPs for all applications to ensure connectivity across regions.
Show answer and explanation
Correct answers: B, C, D
Explanation
To meet the company's requirements for seamless migration and global connectivity, it is essential to enable Bring Your Own IP (BYOIP) to retain existing IP ranges, plan subnet ranges to prevent overlaps, and use IPv6 for future growth and scalability. These steps ensure minimal disruption, efficient IP address management, and support for global operations.
- A. Incorrect.
Private Google Access is useful for accessing Google APIs and services privately but does not address the requirement to retain existing IP ranges or manage global connectivity.
- B. Correct.
Bring Your Own IP (BYOIP) allows the company to migrate its existing IP ranges to Google Cloud, meeting the requirement to retain the current IP addresses.
- C. Correct.
Planning subnet ranges to avoid overlaps with on-premises IP ranges ensures seamless hybrid connectivity and prevents routing issues.
- D. Correct.
Using IPv6 addressing allows for scalability and future growth while accommodating the global nature of the network.
- E. Incorrect.
Configuring Public IPs for all applications is unnecessary and could expose the network to potential security risks. Private IPs can be used with proper routing to ensure secure connectivity across regions.
