Google Associate Cloud Engineer Question 100
Select 3Google Cloud PlatformYou are tasked with deploying a web application on Google Cloud Platform using a managed instance group that automatically adjusts the number of instances based on traffic demand. Which of the following steps are necessary to create an autoscaled managed instance group using an instance template?
- A
Create an instance template specifying the machine type and startup script.
- B
Configure a firewall rule to allow HTTP and HTTPS traffic.
- C
Set up a target pool for load balancing.
- D
Define an autoscaling policy for the managed instance group.
- E
Create the managed instance group using the instance template.
Show answer and explanation
Correct answers: A, D, E
Explanation
To create an autoscaled managed instance group, you must first define the VM configuration using an instance template, specify how the group should scale by setting up an autoscaling policy, and then create the instance group itself using the template. While firewall rules and load balancing configurations are important for network traffic, they are not directly required steps in the creation of the autoscaled managed instance group.
- A. Correct.
An instance template is required to define the configuration of the VM instances within the group, including the machine type and startup script.
- B. Incorrect.
While configuring a firewall rule is important for web traffic, it is not directly related to creating an autoscaled managed instance group.
- C. Incorrect.
A target pool is used for load balancing with legacy networks and is not necessary for setting up an autoscaled managed instance group.
- D. Correct.
An autoscaling policy is essential to define how the instance group should scale in response to load changes.
- E. Correct.
The managed instance group must be created using the instance template to define the initial setup and scaling parameters.
