Question 21

Your organization is planning on using Oracle Cloud Infrastructure (OCI) File Storage Service (FSS). You will be deploying multiple compute instance in Oracle Cloud Infrastructure(OCI) and mounting the file system to these compute instances.
The file system will hold payment data processed by a Database instance and utilized by compute instances to create a overall inventory report. You need to restrict access to this data for specific compute instances and must be allowed/blocked per compute instance's CIDR block.
Which option can you use to secure access?

A.Create a new VCN security list, choose SOURCE TYPE as Service and SOURCE SERVICE as FSS.
Add stateless ingress and egress rules for specific IP address and CIDR blocks.

B.Use 'Export option' feature of FSS to restrict access to the mounted file systems.

C.Create and configure OCI Web Application Firewall service with built in DNS based intelligent routing.

D.Use stateless Security List rule to restrict access from known IP addresses only.

Question 22

You are working on the migration of the web application infrastructure of your company from on-premises to Oracle Cloud Infrastructure. You need to ensure that the DNS cache entries of external clients will not direct them to the on-premises infrastructure after switching to the new infrastructure.
Which of the following options will minimize this problem?

A.Reduce the TTL of the DNS records after the switch.

B.Increase the TTL of the DNS records before the switch.

C.DNS changes propagate fast enough that it is not necessary to take any action.

D.Reduce the TTL of the DNS records before the switch.

E.Increase the TTL of the DNS records after the switch.

Question 23

You notice that a majority of your Oracle Cloud Infrastructure (OCI) resources like compute instances, block volumes, and load balancers are not tagged. You have received a mandate from your CIO to add a predefined set of tags to identify owners for respective OCI resources. E.g. if Chris and Larry each create compute instances in a compartment, the instances that Chris creates include tags that contain his name as the value, while the instances that Larry creates have his name.
Which option is the simplest way to implement this new tagging requirement?

A.Create a default tag for each compartment, which ensure that appropriate tags are applied at the time of resource creation.

B.Create an OCI Identity and Access Management policy requiring users to tag resources with their user name.

C.Create an OCI Identity and Access Management policy to automatically tag a resource with the user name.

D.Create tag variables to automatically tag a resource with the user name.

Question 24

Which of the below options is true regarding Oracle Cloud Infrastructure's load balancing service?

A.The public load balancer applies a floating public IP address to the primary load balancer.

B.A public load balancer is Availability Domain specific in scope.

C.You can dynamically change the load balancer shape to handle more incoming traffic.

D.When you create a private load balancer, the service requires 2 or more subnets to host both the primary and standby load balancers.

Question 25

You have provisioned a new VM.DenseIO2.24 compute instance with local NVMe drives. The compute instance is running production application. This is a write heavy application, with a significant Impact to the business it the application goes down.
What should you do to help maintain write performance and protect against NVMe devices failure.

A.NVMe drive have built in capability to recover themself so no other actions are required

B.Configure RAID 6 for NVMe devices.

C.Configure RAID 1 for NVMe devices.

D.Configure RAID 10 for NVMe devices.
