Topic 1 Question 52
You have an application that will run on Compute Engine. You need to design an architecture that takes into account a disaster recovery plan that requires your application to fail over to another region in case of a regional outage. What should you do?
Deploy the application on two Compute Engine instances in the same project but in a different region. Use the first instance to serve traffic, and use the HTTP load balancing service to fail over to the standby instance in case of a disaster.
Deploy the application on a Compute Engine instance. Use the instance to serve traffic, and use the HTTP load balancing service to fail over to an instance on your premises in case of a disaster.
Deploy the application on two Compute Engine instance groups, each in the same project but in a different region. Use the first instance group to serve traffic, and use the HTTP load balancing service to fail over to the standby instance group in case of a disaster.

Groups are better for management that non-groups so A and B are eliminated. Keeping the the instances in the same project will help maintain consistency, so C is better than D.
👍 26Eroc2019/10/26Yes, but why not choose a cost-effective solution like A, preferring a not required performance optimization solution like C? The question it's just asking for a simple fail over

Google recommend using MIG for Zonal outage and multiple MIG for regional outage https://cloud.google.com/architecture/disaster-recovery#compute-engine sentence says: Compute Engine instances are zonal resources, so in the event of a zone outage instances are unavailable by default. Compute Engine does offer managed instance groups (MIGs) which can automatically scale up additional VMs from pre-configured instance templates, both within a single zone and across multiple zones within a region. MIGs are ideal for applications that require resilience to zone loss and are stateless, but require configuration and resource planning. Multiple regional MIGs can be used to achieve region outage resilience for stateless applications.
