Question #21
You have multiple IAM users who launch different types of compute instances and block volumes every day. As a result, your Oracle Cloud Infrastructure (OCI) tenancy quickly hit the service limit and you can no longer create any new instances. As you are cleaning up the environment, you notice that the majority of the instances and block volumes are untagged. Therefore, it is difficult to pinpoint the owner of these resources and verify if they are safe to terminate.
Because of this, your company has issued a new mandate, which requires adding a predefined set of tags to identify owners before launching compute instances.
Which option is the simplest way to implement this new requirement? (Choose the best answer.)
  1. A
    Create tag variables to automatically tag a resource with the user name.
  2. B
    Create a policy to automatically tag a resource with the user name.
  3. C
    Create a policy using IAM requiring users to tag specific resources. This will allow a user to launch compute instances only if certain tags were defined.
  4. D
    Create tag variables for each compartment to automatically tag a resource with the user name.
  5. E
    Create a default tag for each compartment, which ensures that appropriate tags are applied at resource creation.

Correct Answer:
E

Question #22
You have an Oracle database system in a virtual cloud network (VCN) that needs to be accessible on port 1521 from your on-premises network CIDR
172.17.0.0/24.
You have the following configuration currently:
✑ Virtual cloud network (VCN) is associated with a Dynamic Routing Gateway (DRG), and DRG has an active IPSec connection with your on-premises data center.
✑ Oracle database system is hosted in a private subnet.
✑ The private subnet route table has following configuration.

✑ The private subnet security list has following INGRESS security rule.

✑ The Oracle database system is part of a network security group with following security rules.

However, you are still unable to connect to the Oracle Database system.
Which action will resolve this issue? (Choose the best answer.)
  1. A
    Add an EGRESS rule in private subnet security list as following.
  2. B
    Add an EGRESS rule in network security group as following.
  3. C
    Add a route rule in the private subnet route table as following.
  4. D
    Add an Egress rule in private subnet security list as following.

Correct Answer:
A

Question #23
A retail company runs their online shopping platform entirely on Oracle Cloud Infrastructure (OCI). This is a 3-tier web application that includes a 100 Mbps Load
Balancer, Virtual Machine Instances for web and application tiers, and an Oracle DB Systems Virtual Machine. Due to unprecedented growth, they noticed an increase in the incoming traffic to their website and all users start getting 503 (Service Unavailable) errors.
What is the potential problem in this scenario? (Choose the best answer.)
  1. A
    You did not configure a Service Gateway to allow connection between web servers and Load Balancer.
  2. B
    The Traffic Management Policy is not set to Load Balancer the traffic to the web servers.
  3. C
    The Load Balancer health check status indicates critical situation for half of the backend web servers.
  4. D
    The Database is down hence users cannot access the web site.
  5. E
    All the web servers are too busy and not able to answer any request from users.

Correct Answer:
C

Question #24
An automobile company wants to deploy their CRM application for Oracle Database on Oracle Cloud Infrastructure (OCI) DB Systems for one of its major clients.
In compliance with the business continuity program of the client, they need to provide a Recovery Point Objective (RPO) of 24 hours and a Recovery Time
Objective (RTO) of 1 hour. The CRM application should be available even in the event that an entire OCI Region is down.
Which approach meets these requirements in the most cost effective manner? (Choose the best answer.)
  1. A
    Deploy a 1 node VM Oracle database in one region. Manually Configure a Recovery Manager (RMAN) database backup schedule to take hourly database backups. Asynchronously copy the database backups to object storage in another OCI region. If the primary OCI region is unavailable, launch a new 1 node VM Database in the other OCI region and restore the production database from the backup.
  2. B
    Deploy a 1 node VM Oracle database in one region and replicate the database to a 1 node VM Oracle database in another region using a manual setup and configuration of Oracle Data Guard.
  3. C
    Deploy an Autonomous Transaction Processing database in one region and replicate it to an Autonomous Transaction Processing database in another region using Oracle GoldenGate.
  4. D
    Deploy a 2 node Virtual Machine (VM) Oracle RAC database in one region and replicate the database to a 2 node VM Oracle RAC database in another region using a manual setup and configuration of Oracle Data Guard.

Correct Answer:
B
