Exam Question 12
Question
Which two resources reside exclusively in a single Oracle Cloud Infrastructure Availability Domain? (Choose two.)
A. Identity and Access Management Groups
B. Object Storage
C. Web Application Firewall policy
D. Block volume
E. Compute instance
Answer
D. Block volume
E. Compute instance
Explanation
Availability Domain-Specific Resources:
- DB systems (Oracle Database service)
- ephemeral public IPs
- instances: They can be attached only to volumes in the same availability domain.
- subnets: When you create a subnet, you choose whether it is regional or specific to an availability domain. Oracle recommends using regional subnets.
- volumes: They can be attached only to an instance in the same availability domain.

Exam Question 15
Question
Which two statements are true about Oracle Cloud Infrastructure storage services? (Choose two.)
A. You can take incremental snapshots of Block Volumes, File Storage file systems and Object Storage buckets.
B. You can move Object Storage buckets, Block Volumes and File Storage mount targets between compartments.
C. File Storage uses the network file system (NFS) protocol, whereas Block Volume uses iSCSI.
D. Block Volume service scales to Exabytes per instance, while File Storage service offers unlimited scalability.
E. File storage mount target does not provide a private IP address, while the Object Storage bucket provides one.
Answer
B. You can move Object Storage buckets, Block Volumes and File Storage mount targets between compartments.
C. File Storage uses the network file system (NFS) protocol, whereas Block Volume uses iSCSI.
Explanation
The mount target provides the IP address or DNS name that is used together with a unique export path to mount the file system. You can move mount targets from one compartment to another.
Exam Question 16
Question
You deployed an Oracle Cloud Infrastructure (OCI) compute instance (VM.Standard2.16) to run a SQL database. After a few weeks, you need to increase disk performance by using NVMe disks but keeping the same number of CPUs. As a first step, you terminate the instance and preserve the boot volume. What is the next step?
A. Create a new instance using a VM.Standard1.16 shape using the preserved boot volume and move the SQL Database data to NVMe disks.
B. Create a new instance using a VM.DenseIO2.8 shape using the preserved boot volume and move the SQL Database data to NVMe disks.
C. Create a new instance using a VM.DenseIO2.16 shape using the preserved boot volume and move the SQL Database data to block volume.
D. Create a new instance using a VM.DenseIO2.16 shape using the preserved boot volume and move the SQL Database data to NVMe disks.
Answer
D. Create a new instance using a VM.DenseIO2.16 shape using the preserved boot volume and move the SQL Database data to NVMe disks.
Explanation
Increase disk performance by using NVMe disks you can use Dense IO Shape also as the number of CPUs will not change so we should VM.DenseIO2.16

Question
You provisioned an Oracle Autonomous Data Warehouse (ADW) on Oracle Cloud Infrastructure (OCI) and imported data into ADW. You want to give your business analyst the ability to connect to the ADW database and run queries. Which two actions can help you meet this requirement? (Choose two.)
A. Create a database user account for the business analyst.
B. Grant the predefined database role DWROLE to the database user.
C. Grant unlimited tablespace privilege to the database user.
D. Grant the predefined database role DWADW to the database user.
E. Grant the predefined database role DWUSER to the database user.
Answer
B. Grant the predefined database role DWROLE to the database user.
C. Grant unlimited tablespace privilege to the database user.
Exam Question 18
Question
Which two statements are true about restoring a volume from a block volume backup in Oracle Cloud Infrastructure Block Volume service? (Choose two.)
A. You can restore a volume to any availability domain within the same region where the backup is stored.
B. You can restore only one volume from a manual block volume backup.
C. You can restore a volume from any full volume backup but not from an incremental backup.
D. You can restore a block volume backup to a larger volume size.
E. You can only restore a volume to the same availability domain in which the original block volume resides.
Answer
A. You can restore a volume to any availability domain within the same region where the backup is stored.
D. You can restore a block volume backup to a larger volume size.

Exam Question 20
Question
As a solution architect, you designed the network infrastructure of a three-tier web application on Oracle Cloud Infrastructure (OCI) and the back-end database servers are put in a private subnet. One of your database administrators requests to have private access to OCI object storage service. How should you fulfill this request?
A. Add a new route rule to the private subnet route table to route default traffic to the internet gateway.
B. Attach a public IP address to the instances in the private subnet, and then add a new route rule to the private subnet route table to route default traffic to the internet gateway.
C. Create a dynamic routing gateway (DRG) and attach it to your virtual cloud network (VCN). Add a default route rule to the private subnets route table and set the target as DRG.
D. Create a service gateway, add a new route rule to the private subnet route table that uses object storage as target type.
Answer
D. Create a service gateway, add a new route rule to the private subnet route table that uses object storage as target type.
Explanation
A service gateway lets resources in your VCN privately access specific Oracle services, without exposing the data to an internet gateway or NAT. The resources in the VCN can be in a private subnet and use only private IP addresses. The traffic from the VCN to the service of interest travels over the Oracle network fabric and never traverses the internet.
To give your VCN access to a given service CIDR label, you must enable that service CIDR label for the VCN’s service gateway. You can do that when you create the service gateway, or later after it’s created. You can also disable a service CIDR label for the service gateway at any time.
For traffic to be routed from a subnet in your VCN to a service gateway, you must add a rule accordingly to the subnet’s route table. The rule must use the service gateway as the target.
