Google Professional Cloud Network Engineer Question 201
Select 4Google Cloud PlatformYour organization is planning to implement IPv6 in its Google Cloud environment to support modern networking demands and ensure scalability. Which considerations should you account for when designing and planning an IPv6 network in Google Cloud?
- A
Ensure that all required Google Cloud services support IPv6 before enabling it.
- B
Plan for dual-stack support to enable seamless communication between IPv4 and IPv6 networks.
- C
Deploy IPv6-only networks to eliminate the dependency on IPv4 routing.
- D
Allocate IPv6 address ranges to subnets using Global Unicast Addresses (GUAs) provided by Google Cloud.
- E
Ensure that firewall rules are updated to allow IPv6 traffic where required.
Show answer and explanation
Correct answers: A, B, D, E
Explanation
When planning for IPv6 in Google Cloud, it is important to ensure compatibility with services, implement dual-stack support for a seamless transition, and allocate proper IPv6 address ranges. Additionally, updating firewall rules is necessary to allow IPv6 traffic. However, deploying IPv6-only networks is not currently practical during the transition phase, as many systems still rely on IPv4.
- A. Correct.
Correct: It is critical to verify that the services you intend to use support IPv6 to avoid service disruptions or compatibility issues.
- B. Correct.
Correct: Dual-stack architecture allows for co-existence of IPv4 and IPv6, ensuring compatibility with legacy systems and smooth transition.
- C. Incorrect.
Incorrect: While IPv6-only networks might be a future goal, most environments require dual-stack support during the transition period.
- D. Correct.
Correct: When using IPv6 in Google Cloud, subnets are assigned Global Unicast Addresses (GUAs) for external and internal communication.
- E. Correct.
Correct: Firewall rules must explicitly allow IPv6 traffic, as IPv6 traffic is not automatically permitted by default.
