Question 1:
You have created a new compartment called Production to host some production apps. You have also created users in your tenancy and added them to a Group called “production group“. Your users are still unable to access the Production compartment. How can you resolve this situation?
A. Write an IAM Policy for each specific user granting them access to the production compartment
B. Every compartment you create comes with a predefined set of policies, so no further action is needed
C. Your users get automatic access to all compartments, so no further action is needed
D. Write an IAM Policy for “production_group“ granting it access to the production compartment
Answer: D
Explanation:
When creating a compartment, you must provide a name for it (maximum 100 characters, including letters, numbers, periods, hyphens, and underscores) that is unique within its parent compartment. You must also provide a description, which is a non-unique, changeable description for the compartment, from 1 through 400 characters.
After creating a compartment, you need to write at least one policy for it, otherwise no one can access it (except administrators or users who have permissions set at the tenancy level). When creating a compartment inside another compartment, the compartment inherits access permissions from compartments higher up its hierarchy.
When you create an access policy, you need to specify which compartment to attach it to. This controls who can later modify or delete the policy. Depending on how you‘ve designed your compartment hierarchy, you might attach it to the tenancy, a parent, or to the specific compartment itself.

Question 2:
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. 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
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. Create an NFS export option that allows READ_ONLY access where the source is the CIDR range of the DB System subnet
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
Answer: C
Explanation:
NFS export options enable you to create more granular access control than is possible using just security list rules to limit VCN access. You can use NFS export options to specify access levels for IP addresses or CIDR blocks connecting to file systems through exports in a mount target.

Question 3:
You have a working application in the US East region. The app is a 3-tier app with a database backend. You take regular backups of the database into OCI Object Storage in the US East region. For Business continuity; you are leveraging OCI Object Storage cross-region copy feature to copy database backups to the US West region. Which of the following three steps do you need to execute to meet your requirement?
A. Specify an existing destination bucket
B. Provide an option to choose bulk copying of objects
C. Specify the bucket visibility for both the source and destination buckets
D. Write an IAM policy and authorize the Object Storage service to manage objects on your behalf
E. Choose an overwrite rule
F. Provide a destination object name
Answer: A, D, E
Explanation:
You can copy objects to other buckets in the same region and to buckets in other regions.
You must have the required access to both the source and destination buckets when performing an object copy. You must also have permissions to manage objects in the source and destination buckets.
Because Object Storage is a regional service, you must authorize the Object Storage service for each region carrying out copy operations on your behalf. For example, you might authorize the Object Storage service in region US East (Ashburn) to manage objects on your behalf. Once you authorize the Object Storage service, you can copy an object stored in a US East (Ashburn) bucket to a bucket in another region.
You can use overwrite rules to control the copying of objects based on their entity tag (ETag) values. Specify an existing target bucket for the copy request. The copy operation does not automatically create buckets.

Question 4:
A customer has established an Oracle Cloud Infrastructure (OCI) FastConnect connection to OCI. The virtual circuit is up and routes are being advertised from the customers end, however the customer is unable to ping from compute instances inside the virtual cloud network (VCN) to servers residing in its on-premises data center.
Which two options on OCI would remedy this situation? (Choose two.)
A. Modify the security list associated with the VCN subnet in which the instance resides. Add a stateful egress rule to allow ICMP traffic to the customers on-premises network
B. Modify the route table associated with the VCN subnet in which the instance resides. Add a route to the customers on-premises network via the Dynamic Routing Gateway (DRG)
C. Modify the security list associated with the VCN subnet in which the instance resides. Add a stateful ingress rule to allow ICMP traffic from anywhere
D. Modify the default VCN route table to add a route back to the customers on-premises network via the DRG
Answer: A, B
Explanation:
Your subnet doesn‘t necessarily use the default VCN route table, so you can modify it. You need a route in the subnet of the instance to the on premise network with gateway DRG.
Customer ping initiates from compute instance inside VCN, so without an egress rule the ping won‘t go out, regardless of ingress rule. The stateful egress rule allows to traffic to go out.

Question 5:
You currently manage an e-commerce application that utilizes 25 identical compute resources to handle customer traffic. The stakeholders have asked you to create another 25 identical compute resources in order to deploy and test a new version of the software?
What is the most efficient process to create 25 additional compute resources that are identical to the first 25?
A. Clone the boot volume of 1 of the 25 servers. Use the boot volume clone to provision 25 more servers
B. Create a custom image from 1 of the 25 servers. Use this custom image to provision 25 more servers
C. Provision a new server and configure it to be identical to the first 25. Create a custom image from the new server, then use the custom image to provision 24 more servers
D. Create a manual backup of each boot volume belonging to the 25 servers. Restore each backup to create 25 new boot volumes, from which you will provision 25 more servers
Answer: B
Explanation:
Steps to create Custom Image :
· Open the navigation menu and click Compute. Under Compute, click Instances.
· Click the instance that you want to use as the basis for the custom image.
· Click More Actions, and then click Create custom image.
· In the Create in compartment list, select the compartment to create the custom image in.
· Enter a Name for the image. You can change the name later, if needed. You cannot use the name of a platform image for a custom image. Avoid entering confidential information.
· Show tagging options: If you have permissions to create a resource, then you also have permissions to apply free-form tags to that resource. To apply a defined tag, you must have permissions to use the tag namespace. If you are not sure whether to apply tags, skip this option (you can apply tags later) or ask your administrator.
· Click Create custom image.

Question 6:
You have a high-demand web application running on OCI. Your tenancy administrator has set up a schedule-based autoscaling policy on instance pool with initial size of 5 instances for the application.
Policy 1:
Target pool size: 10 instances
Execution time: 8:30 a.in. on every Monday through Friday, in every month, in every year
Cron expression: 0 30 8 ? * MON-FRI *
Which statement accurately explains the goal of this policy?
A. Goal: A recurring monthly schedule. On all days of the month, set the initial pool size to 5 instances. At 8:30 a.m. on every day of the month, scale out to 10 instances
B. Goal: A one-time schedule with only one scaling out even. At 8:30 a.m., on December 31, 2021, scale the instance pool to 10 instances from 5
C. Goal: A recurring weekly schedule. On all days of the week at 8:30 a.m., scale out the pool to instances from the initial size of 5
D. Goal: A recurring daily schedule. On weekday morning at 8:30 am. Scale out to 10 instances
Answer: D
Explanation:
Autoscaling lets you automatically adjust the number or the lifecycle state of compute instances in an instance pool. This helps you provide consistent performance for your end users during periods of high demand, and helps you reduce your costs during periods of low demand.
A cron expression is a string composed of six or seven fields that represent the different parts of a schedule, such as hours or days of the week. Cron expressions use this format:

Question 7:
You have provisioned an Autonomous Data Warehouse (ADW) database with 16 enabled OCPUs and need to configure the consumer group for your application.
Which two are true when deciding the number of sessions for each application? (Choose two.)
A. The MEDIUM consumer group can run 20 concurrent SQL statements when HIGH consumer group has 0 SQL statements
B. The HIGH consumer group can run up to 16 concurrent SQL statements in addition to 32 concurrent SQL statements in MEDIUM and LOW consumer group each
C. The MEDIUM and LOW consumer group can run up to 16 concurrent SQL statements if HIGH consumer group has 0 SQL statements
D. The HIGH consumer group can run up to 16 concurrent SQL statements as long as MEDIUM and LOW consumer groups have 0 SQL statements
E. The HIGH consumer group can run 3 concurrent SQL statements when MEDIUM consumer group has 0 SQL statements
Answer: A, E
Explanation:
For example, for an Autonomous Data Warehouse with 16 OCPUs,
The HIGH consumer group will be able to run 3 concurrent SQL statements when the MEDIUM consumer group is not running any statements.
The MEDIUM consumer group will be able to run 20 concurrent SQL statements when the HIGH consumer group is not running any statements.
The LOW consumer group will be able to run 4800 concurrent SQL statements.
The HIGH consumer group can run at least 1 SQL statement when the MEDIUM consumer group is also running statements.
When these concurrency levels are reached for a consumer group new SQL statements in that consumer group will be queued until one or more running statements finish.

Question 8:
Which statement is true regarding Autonomous Transaction Processing (ATP)?
A. After terminating a database, the database name is available for immediate reuse
B. A maximum of 2 TB of storage can be enabled for an ATP database
C. A maximum of 8 cores can be enabled for an ATP database
D. A database name cannot be used concurrently for both an Autonomous Data Warehouse (ADW) and an ATP database
Answer: D
Explanation:
The database name must be unique among all Autonomous Data Warehouses and Autonomous Databases in your tenancy in the same region. Terminating an Autonomous Transaction Processing database permanently deletes the instance and removes all automatic backups. You cannot recover a terminated database.
The maximum number of CPUs and maximum storage capacity that can be provisioned in Oracle Autonomous Database In the current release up to 128 CPUs and 128TB can be provisioned from the cloud console. Customers requiring more resources need to call their Oracle account team.

Question 9:
Which two options are necessary for achieving high availability on Oracle Cloud Infrastructure?
A. Attach your block volume form Availability Domain 1 to a compute instance in Availability Domain 2 (and vice versa) so that they are highly available
B. Store your database across multiple regions so that half of the data resides in one region and the other half resides in another region
C. Store your database files on Object Storage so that they are available in all Availability Domains in all regions.
D. Configure your database to have Data Guard in another Availability Domain in Sync mode within a region
E. Distribute your application servers across all Availability Domains within a region
Answer: D, E
Explanation:
Block volumes are AD specific. So volumes are only accessible to instances in the same availability domain. You cannot move a volume between availability domains or regions, they are only accessible within the region or availability domain they were created in.

Question 10:
Which two Oracle Cloud Infrastructure database services allow you to dynamically scale CPU and storage? (Choose two.)
A. Autonomous Transaction Processing (ATP)
B. virtual machine DB system
C. bare metal DB system
D. Autonomous Data Warehouse (ADW)
Answer: A, D
Explanation:
Autonomous Data Warehouse (ADW) and Autonomous Transaction Processing (ATP) scale up both CPU and Storage.
If a bare metal DB system requires more compute node processing power, you can scale up (increase) the number of enabled CPU cores in the system without impacting the availability of that system but you can‘t increase the storage. So Bare Metal scale only CPU.
If the original DB system VM shape uses a single node, running databases on the DB system nodes are sequentially stopped and then restarted on the new shape so this is not dynamic. So VM DB system scale only storage.
