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 from the Domain Registrar's self-service portal.
- 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 OCI Marketplace.
- E. All domains can be retrieved to OCI DNS via DYN.
Answer: A
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 # 20
You plan to upload a large file (3 TiB) to Oracle Cloud Infrastructure (OCI) Object Storage. You would like to minimize 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. You do not need to split the object into parts. Object Storage splits the object into parts and uploads all of the parts automatically.
- B. You do not have to commit the upload after you have uploaded all the object parts.
- C. When you split the object into individual parts, each part can be as large as 50 GiB.
- D. While a multipart upload is still active, you can keep adding parts as long as the total number is less than 10,000.
Answer: C,D
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.

- C. Network Visualizer
- D. Traffic Analytics
Answer: C
Explanation:
Explanation
Network Visualizer is the tool that provides a diagram of the implemented topology of all VCNs in a selected region and tenancy. Network Visualizer is a feature of the OCI Networking service that allows users to view and manage their network resources in a graphical interface. It can help users understand their network topology, troubleshoot issues, and optimize performance. The other options are not tools that provide a diagram of the VCN topology, but rather other features or services of OCI Networking. References: [Network Visualizer]
NEW QUESTION # 22
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 new Object Storage bucket in another region and configure lifecycle policy to move data every 5 days.
- B. Copy the Object Storage bucket to a block volume.
- 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 # 23
When creating an Oracle Cloud Infrastructure (OCI) Virtual Cloud Network (VCN) with the VCN wizard, which THREE gateways are created automatically?
- A. Service Gateway
- B. Internet Gateway
- C. Storage Gateway
- D. Bastion Host
- E. Dynamic Routing Gateway
- F. NAT Gateway
- G. Local Peering Gateway
Answer: A,B,F
Explanation:
Explanation
Internet Gateway, NAT Gateway, and Service Gateway are three gateways that are created automatically when creating a VCN with the VCN wizard. An Internet Gateway allows public traffic between the VCN and the internet. A NAT Gateway allows private traffic from the VCN to access the internet without exposing the VCN resources to incoming internet connections. A Service Gateway allows private traffic from the VCN to access OCI services such as Object Storage, Email Delivery, and Notifications. The other options are not created automatically by the VCN wizard, but can be added manually later if needed. References: [VCN Wizard], [Gateways]
NEW QUESTION # 24
You have a block volume created in the US West (Phoenix) region. You enabled Cross Region Replication for thevolume and selected US West (San Jose) as the destination region. Now, you would like to create a new volumefrom the volume replica in the US West (San Jose) region.
What should you do?
- A. Trigger the replica.
- B. No action required. By default, the replica is available as a block volume.
- C. Initiate the replica.
- D. Activate the replica.
Answer: D
Explanation:
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 # 25
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. Creating a clone takes longer than creating a backup of a volume.
- C. You can change the block volume size when cloning a volume.
- D. You can clone a volume to another region.
Answer: C
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 # 26
You have objects stored in an OCI Object Storage bucket that you want to share with a partner company. You decide to use pre-authenticated requests to grant access to the objects. Which statement is true about preauthenticated requests?
- A. Pre-authenticated requests can be used to delete buckets or objects.
- B. Deleting a pre-authenticated request does not revoke user access to the associated bucket or object.
- C. You cannot edit a pre-authenticated request.
- D. You need to provide your OCI credentials to the partner company.
Answer: C
Explanation:
Explanation
You cannot edit a pre-authenticated request is a true statement about pre-authenticated requests.
Pre-authenticated requests are URLs that allow users to access objects or buckets in OCI Object Storage without requiring additional authentication or authorization. Pre-authenticated requests can be created with an expiration date and time, and can be used for read or write operations. However, once created, pre-authenticated requests cannot be edited, but can only be deleted or extended. The other statements are false about pre-authenticated requests. References: [Pre-Authenticated Requests]
NEW QUESTION # 27
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 14 days.
- C. The instance is either reboot-migrated or rebuilt in place for you.
- D. You will receive another notification to reboot within the next 7 days.
Answer: C
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]
