質問 # 31
You create a file system and then add a 2 GB file. You then take a snapshot of the file system.
What would be the total meteredBytes shown by the File Storage service after the hourly update cycle is complete?
- A. 2.5 GB
- B. 2 GB
- C. 4 GB
- D. 3 GB
正解：B
解説：
Explanation
The total meteredBytes shown by the File Storage service after the hourly update cycle is complete would be 2 GB. This is because snapshots do not consume any additional storage space unless there are changes made to the file system after taking the snapshot. Since no changes were made in this scenario, the snapshot would not add any extra storage cost. References: [Snapshots and MeteredBytes]
質問 # 32
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 are processed after they are uploaded. The process is fast but not immediate. It creates samples and sends them to storage outside of the instances. Which type of instance is ideal for a process like this; short lived and one that keeps the cost low?
- A. On-demand instances
- B. Preemptible instances
- C. Burstable instances
- D. Spot instances
正解：B
解説：
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.

You want a full-featured Identity-as-a-Service (IDaaS) solution that helps you manage workforce authentication and access to all of your Oracle and non-Oracle applications, whether they are SaaS apps, on-premises enterprise apps, or apps that are hosted in the cloud. Which IAM Identity Domain type should you create?
- A. Free
- B. Premium
- C. External User
- D. Oracle Apps Premium
正解：B
解説：
Premium is the IAM Identity Domain type that you should create if you want a full-featured IDaaS solution that helps you manage workforce authentication and access to all of your Oracle and non-Oracle applications. Premium Identity Domain provides users with access to Oracle Identity Cloud Service, which is an IDaaS solution that offers identity management, single sign-on, multifactor authentication, identity governance, and integration with third-party applications. The other options are not IAM Identity Domain types that provide a full-featured IDaaS solution. Reference: [Identity Domains], [Oracle Identity Cloud Service]

Which OCI service would you use?
- A. Logging
- B. Notifications
- C. Audit
- D. Service Connectors
- E. Notifications
正解：C
解説：
Explanation
Audit is the OCI service that would help identify the details of all users who were active in the last six hours along with any REST API calls that were executed. Audit is a service that records all API calls and other actions taken by or on behalf of users in OCI. It can be used to track user activity, monitor compliance, and troubleshoot issues. The other options are not suitable for this task. References: [Audit]
質問 # 36
Which is NOT a valid option for an Oracle Cloud Infrastructure (OCI) compute shape?
- A. Dedicated Virtual Machine Host
- B. Exadata Virtual Machine
- C. Bare Metal
- D. Virtual Machine
正解：B
解説：
Exadata Virtual Machine is not a valid option for an OCI compute shape. Exadata Virtual Machine is a deployment option for Exadata Cloud Service or Exadata Cloud@Customer, which are services that provide dedicated Exadata infrastructure for running Oracle databases in OCI. Exadata Virtual Machine allows you to create multiple virtual machines on each Exadata compute node and isolate them from each other using Oracle VM technology. The valid options for OCI compute shapes are:
Bare Metal: A bare metal instance is a physical server that gives you direct access to the underlying hardware and full isolation from other tenants.
Dedicated Virtual Machine Host: A dedicated virtual machine host is a physical server that hosts only your virtual machine instances and no other tenant's instances.
Virtual Machine: A virtual machine instance is a virtual server that runs on a shared physical server with other tenants' instances.
Burstable: A burstable instance is a virtual machine instance that has a baseline utilization of either 12% or 50% of each CPU core and can burst above the baseline when needed.
質問 # 37
You are using the Oracle Cloud Infrastructure (OCI) Vault service to create and manage Secrets. For your databasepassword, you have created a secret and rotated the secret one time. The secret versions are as follows:
Version Number | Status
-----------------------------------------
2 (latest) | Current
1 | Previous
You later realize that you have made a mistake in updating the secret content for version 2 and want to rollback to version 1.
What should you do to rollback to version 1?
- A. Create a new secret version 3 and set to Pending. Copy the content of version 1 into version 3.
- B. Deprecate version 2 (latest). Create new Secret version 3. Create soft link from version 3 to version 1.
- C. From the version 2 (latest) menu, select "Rollback" and select version 1 when given the option.
- D. From the version 1 menu on the OCI console, select "Promote to Current".
正解：D
解説：
Explanation
From the version 1 menu on the OCI console, select "Promote to Current". The explanation is that when you promote a secret version to current, it becomes the latest version of the secret and is used by default when you access the secret. This way, you can rollback to a previous version of the secret without creating a new version.
質問 # 38
Which of the following statements is true about cloning a volume in the Oracle Cloud Infrastructure (OCI) Block Volume service?
- A. You need to detach a volume before cloning it.
- B. You can change the block volume size when cloning a volume.
- C. You can clone a volume to another region.
- D. Creating a clone takes longer than creating a backup of a volume.
正解：B
解説：
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.
質問 # 39
As a network architect you have deployed a public subnet on your Virtual Cloud Network (VCN) with this security list:
You have also created a network security group (NSG) as shown in the table here, and assigned it to your bastion host:
You have confirmed that routing is correct but when you SSH to the VM from your home over the Internet you are unable to connect.
What could be the problem?
- A. SSH traffic is not allowed in the security list nor on the NSG from the Internet.
- B. Public subnet does not have a route rule to the Internet Gateway.
- C. User will be able to SSH to the VM from the Internet as SSH is open on the NSG.
- D. Internet traffic should be allowed only on the NSG.
正解：A
解説：
SSH traffic is not allowed in the security list nor on the NSG from the Internet is the correct answer. This is because the security list only allows ingress traffic from 10.0.0.24 on port 22, and the NSG only allows ingress traffic from 10.0.0.0/16 on port 22. Neither of them allows ingress traffic from 0.0.0.0/0 (the Internet) on port 22, which is required for SSH access. The other options are not correct, as they do not explain why SSH access is not possible. Reference: [Security Lists], [Network Security Groups]
質問 # 40
Which THREE capabilities are available with the Oracle Cloud Infrastructure (OCI) DNS service?
- A. Creating and managing Identity Access Management (IAM) policies
- B. Creating and managing security lists
- C. Creating and managing records
- D. Creating and managing zones
- E. Viewing all zones
- F. Creating and managing WAF rules
正解：C、D、E
解説：
Explanation
Creating and managing records, creating and managing zones, and viewing all zones are three capabilities that are available with the OCI DNS service. 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]
質問 # 41
Which statement is NOT correct regarding the Oracle Cloud Infrastructure (OI) File System snapshots?
- A. Snapshots are a consistent, point-in-time view of your file systems.
- B. Snapshots are accessible under the root directory of the file system at .snapshot/name.
- C. Before you can clone a file system, at least one snapshot must exist for the file system.
- D. Even if nothing has changed within the file system since the last snapshot was taken, a new snapshot consumes more storage.
正解：D
解説：
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.
References: [Snapshots and Storage Consumption]
質問 # 42
You need to set up instance principals so that an application running on aninstance can call Oracle CloudInfrastructure (OCI) public services, without the need to configure user credentials.
A developer in your team has already configured the application built using an OCISDK to authenticate using theinstance principals provider.
Which is NOTa necessary step to complete this set up?
- A. Deploy the application and the SDK to all the instances that belong to the dynamic group.
- B. Generate Auth Tokens to enable instances in the dynamic group to authenticate with APIs.
- C. Create a policy granting permissions to the dynamic group to access services in your compartment or tenancy.
- D. Create a dynamic group with matching rules to specify which instances can make API calls against services.
正解：B
解説：
Explanation
Generating Auth Tokens to enable instances in the dynamic group to authenticate with APIs is not a necessary step to complete this set up. This is because Auth Tokens are used to authenticate users, not instances, when making API calls to OCI services. Instance principals are a feature that allows instances to authenticate themselves using certificates, without requiring user credentials or Auth Tokens. The other options are necessary steps to complete this set up, as they enable instances in the dynamic group to make API calls against services using instance principals and IAM policies. References: [Instance Principals], [Auth Tokens]
質問 # 43
Which THREE protocols are supported by the Oracle Cloud Infrastructure (OCI) Network Load Balancer?
- A. HTTP
- B. TCP
- C. UDP
- D. BGP
- E. ICMP
- F. iSCSI
正解：B、C、E
解説：
Explanation
The explanation is that the OCI Network Load Balancer supports three protocols: UDP, TCP, and ICMP.
These protocols are used to distribute traffic across multiple backend servers based on different criteria, such as source and destination IP addresses, ports, and ICMP types and codes.
質問 # 44
When defining a query for metric data in Monitoring, which field provides the time window for aggregatingmetric data points plotted on the metric chart?
- A. Dimension
- B. Namespace
- C. Interval
- D. Statistic
正解：C
解説：
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. References: [Interval]
質問 # 45
Which TWO components are optional while creating the Monitoring Query Language (MQL) expressions in the Oracle Cloud Infrastructure (OCI) Monitoring service?
- A. Interval
- B. Dimensions
- C. Metric
- D. Statistic
- E. Grouping Function
正解：B、E
解説：
Explanation
Dimensions and Grouping Function are two optional components while creating the Monitoring Query Language (MQL) expressions in the OCI Monitoring service. Dimensions are key-value pairs that provide additional information about a metric, such as region, compartment, or resource type. Grouping Function is a function that aggregates metric data across one or more dimensions, such as sum, count, or average. The other options are required components for MQL expressions. References: [Dimensions], [Grouping Function]
質問 # 46

- A. Object Versioning does not provide data protection against accidental or malicious object update,
- B. Objects are physically deleted from a bucket when versioning is enabled.
- C. Object Versioning is disabled on a bucket by default.
- D. A bucket that is versioning-enabled can and will always have the latest version of the object in the bucket.
正解：C
解説：
overwrite, or deletion.
Explanation:
Object Versioning is disabled on a bucket by default is a true statement regarding OCI Object Storage Versioning. Object Versioning is a feature that allows users to preserve, retrieve, and restore every version of every object stored in a bucket. Object Versioning is disabled on a bucket by default, but can be enabled or suspended by the user at any time. The other statements are false regarding OCI Object Storage Versioning.
