NO.52 You work for a German company as the Lead Oracle Cloud Infrastructure architect. You have designed a highly scalable architecture for your company’s business critical application which uses the Load Balancer service auto which uses the Load Balancer service, autoscaling configuration for the application servers and a 2 Node VM Oracle RAC database. During the peak utilization period of the- application yon notice that the application is running slow and customers are complaining. This is resulting in support tickets being created for API timeouts and negative sentiment from the customer base.
What are two possible reasons for this application slowness?

Autoscaling configuration for the application servers didn’t happen due to IAM policy that’s blocking access to the application server compartment

The Load Balancer configuration is not sending traffic to the listener of the application servers.

Autoscaling configuration for the application servers didn’t happen due to compartment quota breach of the VM shapes used by the application servers.

Autoscaling configuration for the application servers didn’t happen due to service limit breach of the VM shapes used by the application servers

NO.57 You are working as a solutions architect for an online retail store In Frankfurt which uses multiple compute instance VMs spread among three availability domains In the eu-frankfurt-1 region.
You noticed the website Is having very high traffic, so you enabled autoscaling to sun tee me no f your application but, you observed that one of the availability domains is not receiving any traffic.
What could be wrong In this situation?

Autoscaling only works with single availability domains.

You have to manually acid all three availability domains to your load balancer configuration.

Autoscaling can be enabled for multiple availability domains only in uk-london t region.

Autoscaling is using an Instance Pool configured to create instances in two availability Domains.

You forgot to attach a load balancer to your instance pool configuration.

Autoscaling lets you automatically adjust the number of Compute instances in an instance pool based on performance metrics such as CPU utilization. This helps you provide consistent performance for your end users during periods of high demand, and helps you reduce your costs during periods of low demand.
you can associate a load balancer with an instance pool. If you do this, when you add an instance to the instance pool, the instance is automatically added to the load balancer’s backend set . After the instance reaches a healthy state (the instance is listening on the configured port number), incoming traffic is automatically routed to the new instance.
Instance pools let you provision and create multiple Compute instances based off the same configuration, within the same region.
By default, the instances in a pool are distributed across all fault Domains in a best-effort manner based on capacity. If capacity isn’t available in one fault domain, the instances are placed in other fault domains to allow the instance pool to launch successfully.
In a high availability scenario, you can require that the instances in a pool are evenly distributed across each of the fault domains that you specify. When sufficient capacity isn’t available in one of the fault domains, the instance pool will not launch or scale successfully, and a work request for the instance pool will return an “out of capacity” error. To fix the capacity error, either wait for capacity to become available, or use the UpdateInstancePool operation to update the placement configuration (the availability domain and fault domain) for the instance pool.
during create the instance pool you can select the location where you want to place the instances” In the Availability Domain list, select the availability domain to launch the instances in.
If you want the instances in the pool to be placed evenly in one or more fault domains, select the Distribute instances evenly across selected fault domains check box. Then, select the fault domains to place the instances in.
