Google Associate Cloud Engineer Question 276
Select 2Google Cloud PlatformYour company has deployed a web application on Google Cloud. The application is hosted on Compute Engine instances that do not have external IP addresses. You need to ensure that these instances can connect to external services on the internet to fetch updates. Additionally, you want to manage DNS records for the domain used by the application. What combination of Google Cloud services should you configure to achieve this?
- A
Set up Cloud NAT for the Compute Engine instances
- B
Configure Cloud DNS to manage the domain's DNS records
- C
Assign external IP addresses to the Compute Engine instances
- D
Use a VPN to connect the instances to the internet
- E
Create a Cloud Router to route traffic to the internet
Show answer and explanation
Correct answers: A, B
Explanation
To allow Compute Engine instances without external IP addresses to access the internet, Cloud NAT is used. This enables outbound connections to the internet while keeping the instances secure. For managing DNS records of the application's domain, Cloud DNS is the appropriate service. This combination ensures secure internet access and proper DNS management.
- A. Correct.
Correct. Cloud NAT allows instances without external IP addresses to access the internet for outbound connections, which is necessary for fetching updates.
- B. Correct.
Correct. Cloud DNS is used to manage DNS records for a domain, which is needed to manage the application's domain.
- C. Incorrect.
Incorrect. Assigning external IP addresses is not required as Cloud NAT can handle outbound connections without exposing instances directly to the internet.
- D. Incorrect.
Incorrect. A VPN is not necessary for connecting instances to the internet for outbound traffic.
- E. Incorrect.
Incorrect. While Cloud Router is used with Cloud NAT, it is not sufficient by itself to allow internet connectivity for outbound traffic from instances without external IPs.
