You create an autoscaling configuration of Linux compute instances in Oracle Cloud Infrastructure (OCI). You noticed that your application is running slow.

After checking your compute instances, you noticed that autoscaling is not launching additional instances, even though the existing compute instances already have high memory usage. How can you resolve this issue?

• Modify the scaling policy to monitor memory usage and scale up the number of instances when it meets the threshold.

• Modify the scaling policy to monitor CPU usage and scale up the number of instances when it meets the threshold.

• Install the monitoring agent to all compute instances which will trigger the autoscaling group.

• Install OCI SDK in all compute instances and create a script that will trigger the autoscaling event if there is high memory usage

You developed a microservices based application that runs on Oracle Cloud Infrastructure (OCI) Container Engine for Kubernetes (OKE). You want to provide access to this cluster to other team members.

What should you do to provide access to this cluster using as fewest steps as possible?

• Create a group in OCI Infrastructure Access Management (IAM). Create a policy to grant access to the OKE cluster. Other team members should use OCI Cloud Shell to generate the kubeconfig into their own cloud shell environment and access the cluster using kubectl from cloud shell.

• Create a group in OCI Infrastructure Access Management (IAM). Create a policy to grant access to the OKE cluster. Create individual users and access token for each team member. Other team members should use OCI Cloud Shell to generate the kubeconfig into their own cloud shell environment and access the cluster using kubectl from cloud shell

• Create a group in OCI Infrastructure Access Management (IAM). Create a policy to grant access to the OKE cluster. Create a cluster role and cluster role binding to provide access to the cluster for each team member. Other team members should install oci cli and kubectl locally on their laptop. Use the oci cli to generate the kubeconfig and use kubectl to access the cluster.

• Create a group in OCI Infrastructure Access Management (IAM). Create a policy to grant access to the OKE cluster. Other team members should install oci cli and kubectl locally on their laptop. Use the oci cli to generate the kubeconfig and use kubectl to access the cluster

You have been notified of an application failure indicating that one or more of the Oracle Cloud Infrastructure (OCI) resources have become unavailable. After scanning the Compute and Database consoles, you notice that one of the DB Systems is missing.

What would you do to identify the reason for this missing resource?

• Navigate to the Audit console and search the previous 24 hours for all DELETE request actions to get a list of any resource that was deleted in the past 24 hours.

• Navigate to the Audit console and search the previous 24 hours for all the GET request actions to get a list of every event that occurred in the past 24 hours.

• View the service limits associated with your account to ensure that you have not exceeded the allowable number of DB Systems in your tenancy

• Create a serial console connection to the DB System that does not appear in the management console. Connect to the serial console connection, and then review the system logs under /var/log/messages.

Which two statements are true when Oracle Data Guard is configured (using the Console) between two Virtual Machine DB Systems deployed in Oracle Cloud Infrastructure? (Choose two.)

• Primary is a 1-node RAC DB system and Standby is a 2-node RAC DB system.

• Primary is a 2-node RAC DB system and Standby is a 2-node RAC DB system.

• Primary is a 1-node RAC DB system and Standby is a 1-node RAC DB system.

• Primary is a 2-node RAC DB system and Standby is a 1-node RAC DB system.

• Primary is a Bare Metal DB system and Standby is a 1-node RAC DB system.

You are deploying a highly available web application In Oracle Cloud Infrastructure and have decided to use a public load balancer. The back-end web servers will be distributed across all three availability domains (ADs).

How many subnets should you create to deliver a secure, highly available application?

• two subnets in total; one regional private subnet to host your back-end web servers and one regional public subnet to host your public load load balancer

• two subnets in total; one regional public subnet to host your back-end web servers and one regional private subnet to host your public load load balancer

• three subnets in total; one regional public subnet to host your back-end web servers and two AD specific private subnets to host your private load load balancer.

• one subnet in total; one regional private subnet to host your back-end web servers and your public load balancer

You have hired a new employee to run reports from the Autonomous Data Warehouse (ADW) and are not confident in their SQL writing ability. Into which consumer group will you assign this individual to minimize the impact of their code?

• Lowest

• Medium

• Highest

• High

• Low

You are managing a tier-1 OLTP application on an Autonomous Transaction Processing (ATP) database. Your business needs to run hourly batch processes on this ATP database that may consume more CPUs than what is available on the server.

How can you limit these batch processes to not interfere with the OLTP transactions?

• Configure ATP resource management rules to change CPU/IO shares for the consumer group of batch processes

• Copy OLTP data into new tables in a new table space and run batch processes against these new tables.

• Disable automated backup during the batch process operations.

• ATP is designed for OLTP workload only, you cannot run batch processes on ATP

Which two tagging related items are valid attributes that may be included in payload of an audit log event? (Choose two.)

• Predefined values // Tag variables

• Free-form tags

• Defined tags

• Cost-tracking tags

• Default tags

You are a network architect and have designed the network infrastructure of a three-tier application on Oracle Cloud Infrastructure (OCI). In the architecture, back-end DB servers are in a private subnet. One of your DB administrators requests to have access to OCI object storage service. How can you meet this requirement?

• Add a new route rule to the private subnet route table to route default traffic to the internet gateway.

• Attach a public IP address to the instances in the private subnet, and then add a new route rule to the private subnet route table to route default traffic to the internet gateway.

• Create a dynamic routing gateway (DRG) and attach it to your virtual cloud network (VCN). Add a default route rule to the private subnets route table and set the target as DRG.

• Create a service gateway, add a new route rule to the private subnet route table that uses object storage as target type.

A customer has launched a compute Instance in the Virtual Cloud Network (VCN), which has an Internet gateway, a service gateway, a default security lists and a default route table. Customer has opened up Port 22 in the security lists attached to the compute instance subnet, however is still unable to connect to compute instances using ssh.

Which option would remedy this situation?

• Modify the route table associated with the VCN subnet in which the instance resides. Add a following route to the route table.

  Destination CIDR: 0.0.0.0/0

  Target: Internet Gateway (IGW)

• Modify the security list associated with the VCN subnet in which the instance resides. Add a stateful egress rule to allow icmp traffic in addition to the port 22.

• Modify the route table associated with the VCN subnet in which the instance resides. Add a following route to the route table. Destination CIDR: 0.0.0.0/0

  Target: Dynamic Routing Gateway (DRG)

• Modify the route table associated with the VCN subnet in which the instance resides. Add a following route to the route table. Destination CIDR: 0.0.0.0/0

  Target: Service Gateway (SGW)
