NEW QUESTION # 23
Which statement is TRUE about delegating an existing domain to the OracleCloud Infrastructure (OCI) DNS service?
- A. Domains can be delegated to OCI DNS from the OCI Marketplace.
- B. Domains can be delegated to OCI DNS via FastConnect partners.
- C. Domains can be self-delegated to OCI DNS from its own service portal.
- D. Domains can be delegated to OCI DNS from the Domain Registrar's self-service portal.
- E. All domains can be retrieved to OCI DNS via DYN.
Answer: D
Explanation:
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 # 24
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. Copy the Object Storage bucket to a block volume.
- B. Create a new Object Storage bucket in another region and configure lifecycle policy to move data every 5 days.
- C. Create a lifecycle policy to regularly send data from the Standard to Archive storage.
- D. Create a replication policy to send data to a different bucket in another OCI region.
Answer: D
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 # 25
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. External User
- B. Premium
- C. Free
- D. Oracle Apps Premium
Answer: B
Explanation:
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]
NEW QUESTION # 26
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 # 27
Which is NOT a valid Oracle Cloud Infrastructure (OCI) Virtual Cloud Network (VCN) approach?
- A. Private subnets should ideally have individual route tables to control the flowof traffic within and outsideof VCN.
- B. Use OCI tags to tag VCN resources so that all resources follow organizational tagging/naming conventions.
- C. Ensure not all IP addresses are allocated at once within a VCN or subnet; instead reserve some IP addresses for future use.
- D. Ensure VCN CIDR prefix overlaps with other VCNs in your tenancy or withyour organizations private IPnetwork ranges.
Answer: D
Explanation:
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.
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. $59,500.00
- B. $0.00 (free with OCI)
- C. $59,415.00
- D. $150,000.00
Answer: A
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 # 29
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. Create a dynamic group with matching rules to specify which instances can make API calls against services.
- B. Create a policy granting permissions to the dynamic group to access services in your compartment or tenancy.
- C. Deploy the application and the SDK to all the instances that belong to the dynamic group.
- D. Generate Auth Tokens to enable instances in the dynamic group to authenticate with APIs.
Answer: D
Explanation:
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]

NEW QUESTION # 31
As your company's cloud architect, you have been invited by the CEO to join his staff meeting. They want your input on interconnecting Oracle Cloud Infrastructure (OCI) to another cloud provider in London, with some specific requirements:
* They want resources in the other cloud provider to leverage OCI Autonomous Data Warehouse ML capabilities.
* The connection between OCI and the other cloud provider should be provisioned as quickly as possible.
* The connection should offer high bandwidth and predictable performance.
Which other cloud provider should you recommend to interconnect with OCI and meet the above requirements?
- A. Microsoft Azure
- B. Digital Ocean
- C. Alibaba Cloud
- D. OCI
- E. Google Cloud
- F. IBM Cloud
- G. Amazon Web Services
Answer: A
Explanation:
The explanation is that Microsoft Azure is one of the cloud providers that has an interconnect location with OCI in London. This means that you can use OCI FastConnect to establish a private and dedicated connection between OCI and Azure in London, with high bandwidth and predictable performance. This connection can also enable you to leverage OCI Autonomous Data Warehouse ML capabilities from Azure resources, as you can access OCI services across regions using private IP addresses. The interconnect location can be provisioned quickly using the OCI and Azure consoles or APIs.
NEW QUESTION # 32
You 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, therefore you have provisioned one using the file storage service (FSS).
You have also created the corresponding mount target in one of the application subnets. The VCN security lists are properly configured so that the application servers can access FSS. The security team changed the settings for the DB System to have read-only access to the file system. However when they test it, they are unable to access FSS.
How would you allow access to FSS?
- A. Change the ingress rules corresponding to the DB System subnet to be stateful.
- B. 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.
- C. Create an NFS export option that allows READ_ONLY access where the source is the CIDR range of the DB System subnet.
- D. 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.
- E. Modify the security list associated with the subnet where the mount target resides.
Answer: C
Explanation:
Creating an NFS export option that allows READ_ONLY access where the source is the CIDR range of the DB System subnet is the correct answer. This is because NFS export options are used to control the level of access that clients have to file systems. By creating an NFS export option with READ_ONLY access for the DB System subnet, you can allow the DB System to read data from the file system, but not write or modify it. The other options are not correct, as they do not address the requirement of read-only access for the DB System. Reference: [NFS Export Options]
NEW QUESTION # 33
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. Statistic
- B. Interval
- C. Dimension
- D. Namespace
Answer: B
Explanation:
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]
NEW QUESTION # 34
Which is NOT a valid Oracle Cloud Infrastructure (OCI) Virtual Cloud Network (VCN) approach?
- A. Ensure VCN CIDR prefix overlaps with other VCNs in your tenancy or with your organizations private IP network ranges.
- B. Private subnets should ideally have individual route tables to control the flow of traffic within and outside of VCN.
- C. Use OCI tags to tag VCN resources so that all resources follow organizational tagging/naming conventions.
- D. Ensure not all IP addresses are allocated at once within a VCN or subnet; instead reserve some IP addresses for future use.
Answer: A
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.
NEW QUESTION # 35
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. API Signing Key
- B. SSH Key Pair with 2048-bit algorithm
- C. Auth Tokens
- D. OCI Username and Password
Answer: C
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]
NEW QUESTION # 36
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 need to detach a volume before cloning it.
- C. You can clone a volume to another region.
- D. You can change the block volume size when cloning a volume.
Answer: D
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 # 37
In which two ways can Oracle Security Zones assist with the cloud security shared responsibility model?
- A. Deny public access to Oracle Cloud Infrastructure resources, such as databases and object storage buckets.
- B. Encrypt storage resources with a customer-managed key.
- C. Allow access to an unsecured compartment, which is moved from a standard compartment.
- D. Add or move a standard compartment to a highly secured security zone compartment.
Answer: A,B
Explanation:
Explanation
Oracle Security Zones is a service that helps you enforce best practices and prevent misconfigurations on your OCI resources by applying predefined policies and controls. Some of the benefits of using Security Zones are:
Encrypt storage resources with a customer-managed key: Security Zones require that all storage resources, such as block volumes, boot volumes, file systems, and object storage buckets, are encrypted with a customer-managed key from Vault. This ensures that you have full control over the encryption and decryption of your data at rest.
Deny public access to OCI resources, such as databases and object storage buckets: Security Zones prevent you from creating or updating OCI resources that have public access enabled, such as databases and object storage buckets that are accessible from the internet. This reduces the risk of unauthorized access or data leakage.
NEW QUESTION # 38
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. From the version 1 menu on the OCI console, select "Promote to Current".
- B. Create a new secret version 3 and set to Pending. Copy the content of version 1 into version 3.
- C. Deprecate version 2 (latest). Create new Secret version 3. Create soft link from version 3 to version 1.
- D. From the version 2 (latest) menu, select "Rollback" and select version 1 when given the option.
Answer: A
Explanation:
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.
NEW QUESTION # 39
You are backing up your on-premises data to the Oracle Cloud Infrastructure (OCI) Object Storage Service.
Your requirements are:
1. Backups need to be retained for at least full 31 days.
2. Data should be accessible immediately if and when needed after the backup.
Which OCI Object Storage tier is suitable for storing the backup to minimize cost?
- A. Infrequent Access tier
- B. Auto-Tiering tier
- C. Standard tier
- D. Archive tier
Answer: A
Explanation:
Explanation
The explanation is that the Infrequent Access tier is suitable for storing data that is accessed less frequently but requires immediate access when needed. The Infrequent Access tier has lower storage costs than the Standard tier, but higher retrieval costs. The Infrequent Access tier also has a minimum storage duration of 30 days, which means that you will be charged for at least 30 days of storage even if you delete or move the data before that period.
NEW QUESTION # 40
Which THREE capabilities are available with the Oracle Cloud Infrastructure (OCI) DNS service?
- A. Creating and managing records
- B. Creating and managing zones
- C. Creating and managing WAF rules
- D. Creating and managing security lists
- E. Creating and managing Identity Access Management (IAM) policies
- F. Viewing all zones
Answer: A,B,F
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. Reference: [DNS Service], [Records], [Zones]

Which TWO are key benefits of setting up Site-to-Site VPN on Oracle Cloud Infrastructure (OCI)?
- A. When setting up Site-to-Site VPN, it creates a private connection that provides consistent network experience.
- B. When setting up Site-to-Site VPN, OCI provisions redundant VPN tunnels.
- C. When setting up Site-to-Site VPN, customers can configure it to use static or dynamic routing (BGP).
- D. When setting up Site-to-Site VPN, customers can expect bandwidth above 2 Gbps.
Answer: B,C
Explanation:
When setting up Site-to-Site VPN, customers can configure it to use static or dynamic routing (BGP). When setting up Site-to-Site VPN, OCI provisions redundant VPN tunnels. The explanation is that Site-to-Site VPN is a secure and encrypted connection between your on-premises network and your Virtual Cloud Network (VCN) in OCI over the public internet. When setting up Site-to-Site VPN, you can choose to use static routing or dynamic routing (Border Gateway Protocol or BGP) to exchange routes between your network and OCI. OCI also provisions two redundant VPN tunnels for each Site-to-Site VPN connection to provide high availability and failover.
