You are running an online gaming application hosted on a VM.Standard2.1 instance shape in Oracle Cloud
Infrastructure. As the game becomes popular, you identify network throughput as a bottleneck on your
instance when uploading user data.
Though you want to resolve the issue, you want to observe the demand for a week before adding new
application instances.
Which action is the most efficient way to resolve this issue?
A. Add a secondary virtual network interface card (VNIC).
B. Change shape of the instance to a higher network bandwidth instance.
C. Delete the instance while preserving boot volume and spin up a new higher network bandwidth instance with this boot volume.
D. Change the performance tier of attached block volume to High Performance.
You have created a virtual cloud network (VCN) with three private subnets. Two of the subnets contain application servers and the third subnet contains a DB System. The application requires a shared file system so you have provisioned one using the file storage service (FSS). You also created the corresponding mount target in one of the application subnets. The VCN security lists are properly configured so that both application servers and the DB System can access the file system. The security team determines that the DB System should have read-only access to the file system. What change would you make to satisfy this requirement?
A. Create an NFS export option that allows READ_ONLY access where the source is the CIDR range of the DB System subnet.
B. Connect via SSH to one of the application servers where the file system has been mounted. Use the Unix command chmod to change permissions on the file system directory, allowing the database user read only access.
C. Modify the security list associated with the subnet where the mount target resides. Change the ingress rules corresponding to the DB System subnet to be stateless.
D. Create an instance principal for the DB System. Write an Identity and Access Management (IAM) policy that allows the instance principal read-only access to the file storage service.
At the end of a terraform apply operation, what is the default output?
A. nothing by default
B. statistics about what was added, changed, and destroyed
C. the entire state file
D. statistics about what was added, changed, and destroyed, and the values of outputs
Which three actions are required to configure a highly available and secure hybrid network between Oracle Cloud and your data center? (Choose three.)
A. Define a non-overlapping IP Address Space between the data center and the cloud.
B. Configure each of the CPEs to leverage each of the IPSec Tunnels created by the connection process.
C. Create two or more CPEs that map to the private IP addresses of the customer routers used in the IPSec VPN Tunnel.
D. Define a default route table entry for the VCN that directs all traffic to the data center network to a single DRG.
E. Create dynamic routing gateways in more than one AD within your region.
Which three load-balancing policies can be used with a back end set? (Choose three.)
A. Throughput
B. IP Hash
C. Weighted Round Robin
D. CPU Utilization
E. Least Connections
Within your tenancy you have a compute instance with a boot volume and a block volume attached. The boot volume contains the OS and the attached block volume contains the instance's important dat
A. Logs on the boot volume have filled the boot volume and are causing issues with the OS. What should you do to resolve this situation?
B. Stop the instance that is full. Create a manual backup of the block storage before making changes. Detach the block volume, create a new instance of the same shape with a larger custom boot volume and attach the block volume to the new instance. Configure the OS and any related application(s) to access the block volume under the same mount point as before.
C. Create a new instance with a larger boot volume size as well a new block volume which is the same size or larger than the one attached to the full instance. rsync the state of the boot volume and the state of the block volume between the two instances.
D. Detach the block volume from the full instance. Create a new instance of the same shape with a larger boot volume and rsync the state of the boot volume between the instances. Attach the block volume to the new instance.
E. Create a manual backup of the block storage instance. Create a custom image of the full instance. Once that completes deploy the custom image to a new instance.
You had an outage in your application caused by the loss of a shared volume provisioned by File Storage
Service (FSS). At this point, you need to restore the data from a snapshot you created of the FSS.
What are the steps to restore the data?
A. Access the directory where the shared volume is mounted, then cd into .snapshot folder, find the snapshot folder you want to recover and use cp or rsync tool to copy the files to the original location.
B. Open OCI Console, select File Storage Service, find the shared storage, then click on snapshot and restore.
C. Open OCI Console, select File Storage Service, find the snapshot you created and click restore.
D. Access the directory, where you mounted the shared volume, then cd into .snapshot folder and find the snapshot folder you want to recover and rename that folder to the original folder name.
Which two options are true for Autonomous Transaction Processing (ATP) database? (Choose two.)
A. You can add/remove Diskgroup in ATP
B. You can scale storage up or down in ATP
C. You can scale CPU up or down in ATP
D. You can add more Pluggable Database for consolidating multiple databases in ATP
E. You can add new ORACLE_HOME for bringing older versions of on-premises databases to ATP
In what two ways does Oracle Cloud Infrastructure (OCI) file storage service differ from OCI object storage and block volume services?
A. You can move object storage buckets, block volumes and file storage mount targets between compartments.
B. File Storage uses the network file system (NFS) protocol, whereas block volume uses iSCSI.
C. Block volume service Is NVMe based, while file storage service is not.
D. File storage mount target does not provide a private IP address, while the object storage bucket provides one.
Your application consists of three Oracle Cloud Infrastructure compute instances running behind a public load balancer. You have configured the load balancer to perform health checks on these instances, but one of the three instances fails to pass the configured health check. Which of the following action will the load balancer perform?
A. Stop sending traffic to the instance that failed health check
B. Terminate the instance that failed health check
C. Stop the instances that failed health check
D. Remove the instance that failed the health check from the backend set
