Question 16

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?

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

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

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

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

Question 17

You are designing a networking infrastructure in multiple Oracle Cloud Infrastructure regions and require connectivity between workloads in each region. You have created a dynamic routing gateway (DRG) and a remote peering connection. However, your workloads are unable to communicate with each other.
What are two reasons for this? (Choose two.)

A.The route table associated with subnets in each VCN do not have a route rule defined to forward the traffic to their respective DRGs.

B.A local peering gateway needs to be created in each VCN with a default route rule added in the route table forwarding the traffic to the local peering gateway.

C.The security lists associated with subnets in each virtual cloud network (VCN) do not have the appropriate ingress rules.

D.Identity and Access Management (IAM) policies have not been defined to allow connectivity across the two VCNs in different regions.

E.An internet gateway needs to be created in each VCN with a default route rule added in the route table forwarding the traffic to the internet gateway

Question 18

You have multiple applications installed on a compute instance and these applications generate a large amount of log files. These log files must reside on the boot volume for a minimum of 15 days and must be retained for at least 60 days. The 60-day retention requirement is causing an issue with available disk space.
What are the two recommended methods to provide additional boot volume space for this compute instance?
(Choose two.)

A.Terminate the instance while preserving the boot volume. Create a new instance from the boot volume and select a DenseIO shape to take advantage of local NVMe storage.

B.Create an object storage bucket and use a script that runs daily to move log files older than 15 days to the bucket.

C.Create and attach a block volume to the compute instance and copy the log files.

D.Create a custom image and launch a new compute instance with a larger boot volume size.

E.Write a custom script to remove the log files on a daily basis and free up the space on the boot volume.

Question 19

As the Cloud Architect for your company, you have been tasked with designing a high performance (HPC) cluster in Oracle Cloud Infrastructure (OCI). The following requirements have been defined:
The cluster must be a minimum of three nodes, but may increase to six nodes when demand requires.
The cluster must be resilient to any potential infrastructure failures.
To minimize latency, all nodes must be deployed within the same availability domain (AD).
Adding or replacing nodes within the cluster should take no more than 30 minutes.
Which two steps should be performed to satisfy these requirements in OCI? (Choose two.)

A.Deploy the cluster in a single AD with a shared file system that leverages the file storage service (FSS). Deploy a standby cluster in another AD and configure it to use the same shared file system.

B.Deploy the cluster in a single AD. Place each of the nodes in one of the three different fault domains in that AD.

C.Create a backup of your HPC node compute instance boot volume. Launch new compute instances directly from the backup reduce provisioning time.

D.Create a custom image of your HPC node compute instance. Launch new compute instances using this image to reduce provisioning time.

E.Deploy the cluster in a single AD. Place each of the nodes in a different virtual cloud network (VCN) subnet.

Question 20

You have been asked to create an Identity and Access Management (IAM) user that will authenticate to Oracle Cloud Infrastructure (OCI) API endpoints. This user must not be given credentials that would allow them to log into the OCI console.
Which two authentication options can you use? (Choose two.)

A.SSL certificate

B.API signing key

C.SSH key pair

D.PEM Certificate file

E.Auth token
