Which statement is true regarding OCI Object Storage Versioning?
- A. A bucket that is versioning-enabled can and will always have the latest version of the object in the bucket.
- B. Objects are physically deleted from a bucket when versioning is enabled.
- C. Object Versioning does not provide data protection against accidental or malicious object update,
- D. Object Versioning is disabled on a bucket by default.
Answer: D
Explanation:
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. Reference: [Object Versioning]
NEW QUESTION # 33
Which TWO statements are TRUE about Private IP addresses in Oracle Cloud Infrastructure (OCI)?
- A. By default, the primary VNIC of an instance in a subnet has one primary private IP address.
- B. By default, the primary VNIC of an instance in a subnet has one primary private IP address and one secondary private IP address.
- C. A private IP can have an optional public IP assigned to it if it resides in a public subnet.
- D. Each VNIC can only have one private IP address.
Answer: A,C
Explanation:
Explanation
By default, the primary VNIC of an instance in a subnet has one primary private IP address. A private IP can have an optional public IP assigned to it if it resides in a public subnet. The explanation is that a private IP address is an IPv4 address that is assigned to a VNIC and belongs to the CIDR block of the VCN or subnet.
By default, the primary VNIC of an instance in a subnet has one primary private IP address, which is automatically assigned by OCI and cannot be changed. However, you can also assign secondary private IP addresses to a VNIC, either manually or automatically, up to a maximum of 31 per VNIC. A private IP address can have an optional public IP address assigned to it, which allows the instance to communicate with the internet. A public IP address can be either ephemeral or reserved, depending on whether you want to keep it after stopping or terminating the instance. A private IP address can only have a public IP address assigned to it if it resides in a public subnet, which means that the subnet's route table has a route rule that directs traffic to the internet gateway.
NEW QUESTION # 34
As a network architect you have been tasked with creating a fully redundant connection from your on-premisesdata center to your Virtual Cloud Network (VCN) in the us-ashburn-1 region.Which TWO options will accomplish this requirement?
- A. Configure two FastConnect virtual circuits to the us-ashburn-1 region and terminate them in diverse hardware on-premises.
- B. Configure one FastConnect virtual circuit to the us-ashburn-1 region andthe second FastConnect virtual circuit to the us-phoenix-1 region.
- C. Configure one FastConnect virtual circuit to the us-ashburn-1 region and a Site-to-Site VPN to the usashburn-1 region.
- D. Configure a Site-to-Site VPN from a single on-premises CPE.
Answer: A,C
Explanation:
Explanation
Configure two FastConnect virtual circuits to the us-ashburn-1 region and terminate them in diverse hardware on-premises. Configure one FastConnect virtual circuit to the us-ashburn-1 region and a Site-to-Site VPN to the us-ashburn-1 region. The explanation is that FastConnect is a service that provides a private and dedicated connection between your on-premises network and your VCN in OCI. FastConnect offers higher bandwidth, lower latency, and more consistent network performance than public internet connections. To create a fully redundant connection from your on-premises data center to your VCN in the us-ashburn-1 region, you can either configure two FastConnect virtual circuits to the same region and terminate them in diversehardware on-premises, or configure one FastConnect virtual circuit to the region and a Site-to-Site VPN to the same region as a backup option.

NEW QUESTION # 36
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 have to commit the upload after you have uploaded all the object parts.
- B. You do not need to split the object into parts. Object Storage splits the object into parts and uploads all of the parts automatically.
- 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.

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 CPUutilization.
- B. Burstable instances cost less than regular instances with the same total OCPU count.
- C. If the instance's average CPU utilization over the past 24 hours is below thebaseline, the system allows itto burst above the baseline.
- D. Burstable instances are charged according to the baseline OCPU.
- E. Baseline utilization is a fraction of each CPU core, either 25% or 75%.
Answer: A,E
Explanation:
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 # 44
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. You will receive another notification to reboot within the next 14 days.
- B. The instance will get terminated.
- 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]
NEW QUESTION # 45
You are in the process of migrating several legacy applications from on-premises to Oracle Cloud Infrastructure (OCI). The current servers are already virtualized. However, you notice that the version of CentOS currentlyrunning does not align with any of the Oracle-provided compute images.How would you migrate your existing virtual server images to OCI?
- A. Export your current image in the QCOW2 format and copy to an Object Storage bucket. Import it as a custom image. Select emulated mode to ensure compatibility with legacy drivers
- B. Export your current image in the VMDK format and copy to an Object Storage bucket. Import it as a custom image. Select native mode to ensure the best possible performance.
- C. Export your current image in the VDI format and copy to an Object Storagebucket. Import it as a customimage. Select native modeto ensure the best possible performance.
- D. Export your current image in the QED format and copy to an Object Storagebucket. Import it as a customimage. Select emulated modeto ensure compatibility with legacy drivers.
Answer: A
Explanation:
Explanation
Export your current image in the QCOW2 format and copy to an Object Storage bucket. Import it as a custom image. Select emulated mode to ensure compatibility with legacy drivers. The explanation is that QCOW2 is one of the supported formats for importing custom images to OCI. Custom images are images that you can create from your own on-premises or cloud servers and use them to launch instances in OCI. To import a custom image, you need to export your current image in a supported format, copy it to an Object Storage bucket, and then import it as a custom image using the OCI console or API. When you import a custom image, you can choose between native mode or emulated mode. Native mode offers better performance but requires compatible drivers and firmware. Emulated mode offers better compatibility but lower performance.
