NEW QUESTION # 28
Which TWO statements are NOTcorrect regarding the Oracle Cloud Infrastructure (OCI) burstable instances?
- A. Burstable instances are designed for scenarios where an instance is not typically idle and has high CPU utilization.
- B. 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.
- C. Burstable instances are charged according to the baseline OCPU.
- D. Baseline utilization is a fraction of each CPU core, either 25% or 75%.
- E. Burstable instances cost less than regular instances with the same total OCPU count.
Answer: A,D
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 # 29
When defining a query for metric data in Monitoring, which field provides the time window for aggregating metric data points plotted on the metric chart?
- A. Statistic
- B. Namespace
- C. Dimension
- D. Interval
Answer: D
Explanation:
Interval is the field that provides the time window for aggregating metric data points plotted on the metric chart. Interval is a parameter that specifies how often metric data points are collected and aggregated by the Monitoring service. For example, an interval of 5 minutes means that metric data points are aggregated every 5 minutes and displayed on the chart. The other options are not fields that provide the time window for aggregating metric data points, but rather other parameters that define the metric query. Reference: [Interval]
NEW QUESTION # 30
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. The storage administrator forgot to select "Encrypt using Oracle managed keys" while creating the bucket.
- B. There is no Identity and Access Management (IAM) policy that allows the Object Storage service to use thekey.
- C. The secret for the key was not created beforehand
- D. The Object Storage bucket policy lacks the necessary Access Control List (ACL).
Answer: B
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 # 31
Which of the following statements is true about cloning a volume in the Oracle Cloud Infrastructure (OCI) Block Volume service?
- A. Creating a clone takes longer than creating a backup of a volume.
- B. You can change the block volume size when cloning a volume.
- C. You need to detach a volume before cloning it.
- D. You can clone a volume to another region.
Answer: B
Explanation:
You can change the block volume size when cloning a volume. The explanation is that cloning a volume is a way of creating an exact copy of an existing volume without creating a backup first. Cloning a volume is faster and cheaper than creating a backup and restoring it to a new volume. When you clone a volume, you can change the block volume size, performance, encryption settings, and tags of the new volume. You do not need to detach a volume before cloning it, as cloning does not affect the source volume or its attachments. You cannot clone a volume to another region, as cloning only works within the same region and availability domain. Creating a clone usually takes less time than creating a backup of a volume, as cloning does not involve transferring data to Object Storage.
NEW QUESTION # 32
You plan to launch a VM instance with the VM.Standard2.24 shape and Oracle Linux 8 platform image. You wantto protect your VM instance from low-level threats, such as rootkits and bootkits that can infect the firmwareand operating system and are difficult to detect.
What should you do?
- A. Create a burstable instance.
- B. Create a shielded instance.
- C. Use in-transit encryption.
- D. Use Vulnerability Scanning Service.
Answer: B
Explanation:
Explanation
The explanation is that shielded instances are VM instances that have additional security features to protect them from low-level threats, such as rootkits and bootkits that can infect the firmware and operating system and are difficult to detect. Shielded instances use verified boot, which ensures that only trusted software components are executed during the boot process. Shielded instances also use virtual trusted platform module (vTPM), which provides a secure storage for encryption keys and certificates. Shielded instances are available for Oracle Linux 8 platform images with VM.Standard2.* shapes.
NEW QUESTION # 33
You are responsible for deploying an application on Oracle Cloud Infrastructure (OCI). The application is memoryintensive and performs poorly if enough memory is not available.

NEW QUESTION # 34
You plan to upload a large file (3 TiB) to Oracle Cloud Infrastructure (OCI) Object Storage. You would like tominimize the impact of network failures while uploading, and therefore you decide to use the multipart upload capability.
Which TWO statements are true about performing a multipart upload using the Multipart Upload API?
- A. While a multipart upload is still active, you can keep adding parts as long asthe total number is less than10,000.
- B. When you split the object into individual parts, each part can be as large as 50 GiB.
- C. You do not need to split the object into parts. Object Storage splits the object into parts and uploads all ofthe parts automatically.
- D. You do not have to commit the upload after you have uploaded all the object parts.
Answer: A,B
Explanation:
Explanation
While a multipart upload is still active, you can keep adding parts as long as the total number is less than
10,000. When you split the object into individual parts, each part can be as large as 50 GiB. The explanation is that a multipart upload allows you to upload a large object in parts, which can improve performance and reliability. You need to split the object into parts yourself and upload each part separately using the Multipart Upload API. You can add parts to an active multipart upload until you reach the maximum number of 10,000 parts per upload. Each part can range from 10 MiB to 50 GiB in size, except for the last part, which can be any size.
NEW QUESTION # 35
You have three compartments: ProjectA, ProjectB, and ProjectC. For each compartment, there is an admin group set up: A-Admins, B-Admins, and C-Admins.
Each admin group has full access over their respective compartments as shown in the graphic below.
Your organization has set up a tag namespace, EmployeeGroup.Role and all your admin groups are tagged with a value of 'Admin'.
You want to set up a Test compartment for members of the three projects to share. You also need to provide admin access to all three of your existing admin groups.
Which policy would you write to accomplish this task?
- A. Allow all-group to manage all-resources in compartment Test where
request.principal.group.tag.EmployeeGroup.Role='Admin' - B. Allow any-user to manage all-resources in compartment Test where request.principal.group.tag.EmployeeGroup.Role='Admin'
- C. Allow dynamic-group to manage all-resources in compartment Test where request.principal.group.tag.EmployeeGroup.Role='Admin'
- D. Allow group any-group to manage all-resources in compartment Test where request.principal.group.tag.EmployeeGroup.Role='Admin'
Answer: B
Explanation:
Allow all-group to manage all-resources in compartment Test where request.principal.group.tag.EmployeeGroup.Role='Admin' is the policy that would accomplish this task. This policy grants admin access to all groups that have the tag EmployeeGroup.Role='Admin' in the compartment Test. The other options are not correct, as they use incorrect terms such as dynamic-group, any-group, or any-user. Reference: [Tag-Based Authorization]
NEW QUESTION # 36
Which statement is NOT correct regarding the Oracle Cloud Infrastructure (OI) File System snapshots?
- A. Before you can clone a file system, at least one snapshot must exist for the file system.
- B. Even if nothing has changed within the file system since the last snapshot was taken, a new snapshot consumes more storage.
- C. Snapshots are a consistent, point-in-time view of your file systems.
- D. Snapshots are accessible under the root directory of the file system at .snapshot/name.
Answer: B
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]

Which statement is TRUE about delegating an existing domain to the Oracle Cloud Infrastructure (OCI) DNS service?
- A. Domains can be delegated to OCI DNS via FastConnect partners.
- B. Domains can be delegated to OCI DNS from the OCI Marketplace.
- C. Domains can be delegated to OCI DNS from the Domain Registrar's self-service portal.
- D. Domains can be self-delegated to OCI DNS from its own service portal.
- E. All domains can be retrieved to OCI DNS via DYN.
Answer: C
Explanation:
Domains can be delegated to OCI DNS from the Domain Registrar's self-service portal. The explanation is that delegating a domain to OCI DNS means that you are transferring the authority to resolve DNS queries for your domain from your current DNS provider to OCI DNS. To delegate a domain to OCI DNS, you need to create a zone in OCI DNS that matches your domain name and add any records that you want to serve from OCI DNS. Then, you need to update the name servers for your domain at your Domain Registrar's self-service portal with the name servers provided by OCI DNS. This will point your domain to OCI DNS and allow it to resolve DNS queries for your domain.
NEW QUESTION # 41
