NEW QUESTION # 22
company sells services to photographers where patrons can preview the photos that they want prints for.
To avoid unauthorized copies, the sample photos have lower resolution and are watermarked. The photos areprocessed after they are uploaded. The process is fast but not immediate. It creates samples and sends them tostorage outside of the instances.Which type of instance is ideal for a process likethis; short lived and one thatkeeps the cost low?
- A. On-demand instances
- B. Preemptible instances
- C. Burstable instances
- D. Spot instances
Answer: B
Explanation:
Explanation
The explanation is that preemptible instances are VM instances that offer lower costs than regular instances but can be reclaimed by OCI at any time due to capacity constraints or after running for a maximum of 24 hours. Preemptible instances are ideal for short-lived and stateless workloads that can tolerate interruptions and do not require guaranteed availability or performance. Preemptible instances are billed by the second at a fixed rate that is lower than regular instances.
NEW QUESTION # 23
Which is NOT a valid Oracle Cloud Infrastructure (OCI) Virtual Cloud Network (VCN) approach?
- A. Use OCI tags to tag VCN resources so that all resources follow organizational tagging/naming conventions.
- B. Private subnets should ideally have individual route tables to control the flow of traffic within and outside of VCN.
- C. Ensure VCN CIDR prefix overlaps with other VCNs in your tenancy or with your organizations private IP network ranges.
- D. Ensure not all IP addresses are allocated at once within a VCN or subnet; instead reserve some IP addresses for future use.
Answer: C
Explanation:
Ensure VCN CIDR prefix overlaps with other VCNs in your tenancy or with your organizations private IP network ranges. The explanation is that a VCN CIDR prefix is the range of IPv4 addresses that can be used within the VCN and its subnets. The VCN CIDR prefix should not overlap with other VCNs in your tenancy or with your organization's private IP network ranges, as this can cause routing conflicts and connectivity issues. You should choose a VCN CIDR prefix that is large enough to accommodate your current and future needs, but not too large to waste IP addresses. You can use any of the private IPv4 address ranges specified in RFC 1918 for your VCN CIDR prefix.

Records are data elements that map domain names to IP addresses or other information. Zones are collections of records that correspond to a domain name or a subdomain name.
The OCI DNS service allows users to create and manage records and zones for their domains or subdomains, as well as view all zones in their tenancy. The other options are not capabilities of the OCI DNS service, but of other OCI services such as WAF, IAM, and Networking. References: [DNS Service], [Records], [Zones]
NEW QUESTION # 27
Which TWO statements are NOTcorrect regarding the Oracle Cloud Infrastructure (OCI) burstable instances?
- A. If the instance's average CPU utilization over the past 24 hours is below the baseline, the system allows it to burst above the baseline.
- B. Burstable instances cost less than regular instances with the same total OCPU count.
- C. Burstable instances are charged according to the baseline OCPU.
- D. Burstable instances are designed for scenarios where an instance is not typically idle and has high CPU utilization.
- E. Baseline utilization is a fraction of each CPU core, either 25% or 75%.
Answer: D,E
Explanation:
The explanation is that burstable instances are VM instances that have a baseline utilization of either 12% or 50% of each CPU core, not 25% or 75%. Burstable instances are designed for scenarios where an instance is typically idle or has low CPU utilization but occasionally needs to burst above the baseline to handle spikes in demand. Burstable instances cost less than regular instances with the same total OCPU count but charge extra for bursting above the baseline OCPU.
NEW QUESTION # 28
Company XYZ is spending $300,000.00 USD per month in egress fees for 7 Petabytes that they consume for Outbound Data Transfer in North America with their current cloud provider. The company is seeking to lower that expense considerably without reducing consumption. You propose migration to OCI because the Gigabyte Outbound Data Transfer in North America costs just $0.0085 USD per month. With OCI, how much will they spend per month for 7 Petabytes of Outbound Data Transfer? (1 Petabyte = 1000 Terabytes)
- A. $0.00 (free with OCI)
- B. $150,000.00
- C. $59,415.00
- D. $59,500.00
Answer: C
Explanation:
Explanation
$59,415.00 is the amount that Company XYZ will spend per month for 7 Petabytes of Outbound Data Transfer in North America with OCI. This is calculated by multiplying 7 Petabytes by 1000 Terabytes (to convert Petabytes to Terabytes), then multiplying by $0.0085 USD (the cost per Gigabyte Outbound Data Transfer in North America), then dividing by 1000 (to convert Gigabytes to Terabytes). The formula is:
(7 * 1000 * 0.0085) / 1000 = $59,415.00

NEW QUESTION # 31
You have an instance running in Oracle Cloud Infrastructure (OCI) that cannot be live-migrated during an infrastructure maintenance event. OCI schedules a maintenance due date within 14 to 16 days and sends you a notification.
What would happen if you choose not to proactively reboot the instance before the scheduled maintenance due date?
- A. The instance will get terminated.
- B. You will receive another notification to reboot within the next 7 days.
- C. You will receive another notification to reboot within the next 14 days.
- D. The instance is either reboot-migrated or rebuilt in place for you.
Answer: D
Explanation:
If you choose not to proactively reboot the instance before the scheduled maintenance due date, the instance is either reboot-migrated or rebuilt in place for you. Reboot-migration is a process where OCI migrates your instance to a new physical host without changing its configuration or public IP address. Rebuild in place is a process where OCI shuts down your instance, performs maintenance on the physical host, and restarts your instance with the same configuration and public IP address. The other options are not correct. Reference: [Reboot-Migration], [Rebuild in Place]
NEW QUESTION # 32

- A. Configure the autoscaling policy to monitor CPU usage and scale up the number of instances when it meets the threshold
- B. Install OCI SDK on all compute instances and create a script that triggers theautoscaling event if there ishigh memory usage.
- C. Install the monitoring agent on all compute instances, which triggers the autoscaling group.
- D. Configure the autoscaling policy to monitor memory usage and scale up the number of instances when itmeets the threshold.
Answer: D
NEW QUESTION # 33
You are a security administrator for your company's Oracle Cloud Infrastructure (OCI) tenancy. Your storage administrator informs you that she cannot associate an encryption key from an existing Vault to a new Object Storage bucket.
What could be a possible reason for this behavior?
- A. There is no Identity and Access Management (IAM) policy that allows the Object Storage service to use thekey.
- B. The secret for the key was not created beforehand
- C. The storage administrator forgot to select "Encrypt using Oracle managed keys" while creating the bucket.
- D. The Object Storage bucket policy lacks the necessary Access Control List (ACL).
Answer: A
Explanation:
Explanation
There is no Identity and Access Management (IAM) policy that allows the Object Storage service to use the key. The explanation is that when you create an Object Storage bucket with encryption using a customer-managed key from Vault, you need to have an IAM policy that allows the Object Storage service to use the key on your behalf. The policy should look like this:
allow service objectstorage-<region> to use key in compartment <compartment-name> where <region> is the region where your bucket resides and <compartment-name> is the compartment where your key resides.
NEW QUESTION # 34
You have a high-demand web application running on Oracle Cloud Infrastructure (OCI). Your tenancy administrator has set up a schedule-based autoscaling policy on instance pool with an initial size of 5 instances for the application.
Policy 1:
Target pool size:10 instances
Execution time:8:30 a.m. 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 recurring daily schedule. On weekday mornings at 8.30 a.m., scale out to 10 instances.
- C. Goal: A one-time schedule with only one scaling out event. At 8:30 a.m., on December 31, 2021, scale the instance pool to 10 instances from 5.
- D. Goal: A recurring weekly schedule. On all days of the week at 8.30 a.m., scale out the pool to 10 instances from the initial size of 5
Answer: B
Explanation:
The explanation is that a schedule-based autoscaling policy allows you to adjust the size of your instance pool based on a cron expression that specifies the date and time of the scaling action. The cron expression consists of six fields: seconds, minutes, hours, day of month, month, and day of week. In this case, the cron expression is 0 30 8 ? * MON-FRI *, which means that the scaling action will occur at 8:30 a.m. on every Monday through Friday, regardless of the day of month or month. Therefore, the goal of this policy is to scale out the instance pool to 10 instances on weekday mornings at 8:30 a.m.
NEW QUESTION # 35
You have a block volume created in the US West (Phoenix) region. You enabled Cross Region Replication for the volume and selected US West (San Jose) as the destination region. Now, you would like to create a new volume from the volume replica in the US West (San Jose) region.
What should you do?
- A. Trigger the replica.
- B. Initiate the replica.
- C. Activate the replica.
- D. No action required. By default, the replica is available as a block volume.
Answer: C
Explanation:
The explanation is that when you enable Cross Region Replication for a block volume, Object Storage creates a replica of the volume in another region of your choice. The replica is not available as a block volume until you activate it. To activate a replica, you need to select the replica from the Block Storage console and click Activate Replica. This will create a new block volume from the replica in the destination region.
NEW QUESTION # 36
You want to distribute DNS traffic to different endpoints based on the location of the end user. Which Traffic Management Steering Policy would you use?
- A. Failover
- B. IP Prefix
- C. Load Balancer
- D. Geolocation
Answer: D
Explanation:
The explanation is that geolocation is a type of Traffic Management Steering Policy that allows you to distribute DNS traffic to different endpoints based on the location of the end user. Geolocation steering policies use geolocation data from third-party providers to map end user IP addresses to geographic regions. You can create rules that specify which endpoints to serve for each region or country, or use a default endpoint for unspecified regions.
NEW QUESTION # 37
Which statement is NOT correct regarding the Oracle Cloud Infrastructure (OI) File System snapshots?
- A. Even if nothing has changed within the file system since the last snapshot was taken, a new snapshot consumes more storage.
- B. Snapshots are a consistent, point-in-time view of your file systems.
- C. Before you can clone a file system, at least one snapshot must exist for the file system.
- D. Snapshots are accessible under the root directory of the file system at .snapshot/name.
Answer: A
Explanation:
Even if nothing has changed within the file system since the last snapshot was taken, a new snapshot does not consume more storage. This is because snapshots are incremental and only store the changes made to the file system since the previous snapshot. The other statements are correct regarding the OCI File System snapshots. Reference: [Snapshots and Storage Consumption]
NEW QUESTION # 38

Answer: A
Explanation:
It encrypts and isolates in-use data and the applications processing that data, thereby preventing unauthorized access or modification is an accurate description of the key features and benefits of OCI Confidential Computing. Confidential Computing is a feature that leverages hardware-based Trusted Execution Environments (TEEs) to protect data and applications from unauthorized access or modification while they are in use by the CPU or memory. This adds an extra layer of security to cloud computing, as it protects data not only at rest and in transit, but also in use. The other options are not accurate descriptions of the key features and benefits of OCI Confidential Computing. Reference: [Confidential Computing]
NEW QUESTION # 39
A financial firm is designing an application architecture for its online trading platform that should have high availability and fault tolerance.
Their solutions architects configured the application to use an Oracle Cloud Infrastructure (OCI) Object Storage bucket located in the US West (us-phoenix-1) region to store large amounts of financial dat a. The stored financial data in the bucket should not be impacted even if there is an outage in one of the Availability Domains or a complete region.
What should the architect do to avoid any costly service disruptions and ensure data durability?
- A. Create a replication policy to send data to a different bucket in another OCI region.
- B. Copy the Object Storage bucket to a block volume.
- C. Create a new Object Storage bucket in another region and configure lifecycle policy to move data every 5 days.
- D. Create a lifecycle policy to regularly send data from the Standard to Archive storage.
Answer: A
Explanation:
Create a replication policy to send data to a different bucket in another OCI region. The explanation is that replication is a feature of Object Storage that allows you to automatically copy objects from one bucket to another bucket, either in the same region or in a different region. Replication can help you improve data availability and durability, as well as meet compliance and disaster recovery requirements. To enable replication, you need to create a replication policy that specifies the source and destination buckets, the replication frequency, and the replication filters. Replication policies are evaluated every five minutes and copy any new or updated objects from the source bucket to the destination bucket.
NEW QUESTION # 40
Which Oracle Cloud Infrastructure (OCI) Identity and Access Management (IAM) policy is invalid?
- A. Allow any-user to inspect users in tenancy
- B. Allow group A-Admins to manage all-resources in compartment Project-A
- C. Allow group A-Developers to create volumes in compartment Project-A
- D. Allow dynamic-group FrontEnd to manage instance-family in compartment Project-A
Answer: C
Explanation:
Allow group A-Developers to create volumes in compartment Project-A is an invalid IAM policy. This is because create is not a valid verb for volumes. The correct verb for creating volumes is attach. The other options are valid IAM policies that use correct verbs and syntax. Reference: [IAM Policies], [Verbs]
NEW QUESTION # 41
You are using a custom application with third-party APIs to manage the application and data hosted in an Oracle Cloud Infrastructure (OCI) tenancy. Although your third-party APIs do not support OCI's signature-based authentication, you want them to communicate with OCI resources. Which authentication option should you use to ensure this?
- A. SSH Key Pair with 2048-bit algorithm
- B. OCI Username and Password
- C. API Signing Key
- D. Auth Tokens
Answer: D
Explanation:
Auth Tokens is the authentication option that you should use to ensure that your custom application with third-party APIs can communicate with OCI resources. Auth Tokens are tokens that can be used as an alternative to passwords when making API calls to OCI services. Auth Tokens can be generated and revoked by users in the OCI Console or CLI, and can be used with any API client that supports basic authentication. The other options are not suitable for this scenario, as they either require OCI's signature-based authentication or are not applicable for API calls. Reference: [Auth Tokens]
