What is the frequency of OCI Usage Report generation? - Annually - Monthly - Weekly - Daily

- Daily Explanation A usage report is a comma-separated value (CSV) file that can be used to get a detailed breakdown of resources in OCI for audit or invoice reconciliation. The usage report is automatically generated daily, and is stored in an Oracle-owned Object Storage bucket. It contains one row per each OCI resource (such as instance, Object Storage bucket, VNIC) per hour along with consumption information, metadata, and tags. Usage reports generally contain 24 hours of usage data, although occasionally a usage report may contain late-arriving data that is older than 24 hours. Usage reports are retained for one year.

Which service is the most effective for moving large amounts of data from your on- premises to OCI? - Internet Gateway - Data transfer appliance - Dynamic Routing Gateway - Data feed

- Data transfer appliance Explanation Oracle offers offline data transfer solutions that let you migrate data to Oracle Cloud Infrastructure. You can also export data currently residing in Oracle Cloud Infrastructure to your data center offline. Moving data over the public internet is not always feasible because of high network costs, unreliable network connectivity, long transfer times, and security concerns. Our transfer solutions address these pain points, are easy to use, and provide faster data upload compared to over-the-wire data transfer. You send your data as files on secure, high-capacity, Oracle-supplied storage appliances to an Oracle transfer site. Operators at the Oracle transfer site upload the data into your designated Object Storage bucket in your tenancy.This solution supports data transfer when you are migrating a large volume of data and when using disks is not a practical alternative. You do not need to write any code or purchase any hardware. Oracle supplies the transfer appliance and software required to manage the transfer.

- File Storage - Object Storage - Block Volume Explanation: DATA ENCRYPTIONProtect customer data at-rest and in-transit in a way that allows customers to meet their security and compliance requirements for cryptographic algorithms and key management The Oracle Cloud Infrastructure Block Volume service always encrypts all block volumes, boot volumes, and volume backups at rest by using the Advanced Encryption Standard (AES) algorithm with 256-bit encryption. By default all volumes and their backups are encrypted using the Oracle-provided encryption keys. Each time a volume is cloned or restored from a backup the volume is assigned a new unique encryption key. The File Storage service encrypts all file system and snapshot data at rest. By default all file systems are encrypted using Oracle-managed encryption keys. You have the option to encrypt all of your file systems using the keys that you own and manage using the Vault service. Object Storage employs 256-bit Advanced Encryption Standard (AES-256) to encrypt object data on the server. Each object is encrypted with its own data encryption key. Data encryption keys are always encrypted with a master encryption key that is assigned to the bucket. Encryption is enabled by default and cannot be turned off. By default, Oracle manages the master encryption key.

A customer wants to use OCI for starring application backups which can be stored for months but retrieved immediately based on business needs. Which OCI storage service can be used to meet this requirement? - Block volume - Archive storage - Object storage (standard) - File storage

- Object storage (standard) Explanation OCI offers two distinct storage class tiers to address the need for both performant, frequently accessed "hot" storage, and less frequently accessed "cold" storage. Storage tiers help you maximize performance where appropriate and minimize costs where possible. Use Object Storage for data to which you need fast, immediate, and frequent access. Data accessibility and performance justifies a higher price to store data in the Object Storage tier. Use Archive Storage for data to which you seldom or rarely access, but that must be retained and preserved for long periods of time. The cost efficiency of the Archive Storage tier offsets the long lead time required to access the data. Unlike Object Storage, Archive Storage data retrieval is not instantaneous.

Which 2 are enabled OCI Fault Domains? - Protect against unexpected hardware failures or power supply failures. - Build redundant systems for disaster recovery. - Protect Against planned hardware maintenance. - Protect against planned outages because of Computer hardware maintenance.

- Protect against unexpected hardware failures or power supply failures - Protect against planned outages because of Computer hardware maintenance. Explanation A fault domain is a grouping of hardware and infrastructure within an availability domain. Each availability domain contains three fault domains. Fault domains provide anti-affinity: they let you distribute your instances so that the instances are not on the same physical hardware within a single availability domain. A hardware failure or Compute hardware maintenance event that affects one fault domain does not affect instances in other fault domains. In addition, the physical hardware in a fault domain has independent and redundant power supplies, which prevents a failure in the power supply hardware within one fault domain from affecting other fault domains. To control the placement of your compute instances, bare metal DB system instances, or virtual machine DB system instances, you can optionally specify the fault domain for a new instance or instance pool at launch time. If you don't specify the fault domain, the system selects one for you. Oracle Cloud Infrastructure makes a best-effort anti-affinity placement across different fault domains, while optimizing for available capacity in the availability domain. To change the fault domain for an instance, terminate it and launch a new instance in the preferred fault domain.

which statement is correct regarding the OCI Compute services? - You cannot attach a block volume to a compute instance - You can launch either virtual machines or bare metal instances - You can attach a maximum of one public to each compute instance - When you stop a compute instance, all data on the boot volume is lost

- You can launch either virtual machines or bare metal instances Explanation Oracle Cloud Infrastructure offers both bare metal and virtual machine instances: Bare Metal: A bare metal compute instance gives you dedicated physical server access for highest performance and strong isolation. Virtual Machine: A virtual machine (VM) is an independent computing environment that runs on top of physical bare metal hardware. The virtualization makes it possible to run multiple VMs that are isolated from each other. VMs are ideal for running applications that do not require the performance and resources (CPU, memory, network bandwidth, storage) of an entire physical machine. An OCI VM compute instance runs on the same hardware as a bare metal instance, leveraging the same cloud-optimized hardware, firmware, software stack, and networking infrastructure.

Which statement is true for an OCI compute instance? - always get a private IP address - cannot leverage auto scaling feature - always get a public IP address - does not use a boot volume

- always get a private IP address Explanation When you create an instance, the instance is automatically attached to a virtual network interface card (VNIC) in the cloud network's subnet and given a private IP address from the subnet's CIDR. You can let the IP address be automatically assigned, or you can specify a particular address of your choice. The private IP address lets instances within the cloud network communicate with each other.

Cloud __________ Scaling refers to adding more CPU or memory to an existing server, or replacing one server with a more powerful server. Cloud __________ Scaling refers to provisioning additional servers to meet your needs, often splitting workloads between servers to limit the number of requests any individual server is getting. In a cloud-based environment, this would mean adding additional instances instead of moving to a larger instance size.

Which deployment strategy should you adopt? - Use multiple fault domain in any availability domain with multiple regions. - Use multiple fault domains in one regions - Use multiple fault domains in each availability domain in each region - Use multiple availability domains in one Region

Use multiple fault domain in any availability domain with multiple regions Explanation: Availability domains are isolated from each other, fault tolerant, and very unlikely to fail simultaneously. Because availability domains do not share infrastructure such as power or cooling, or the internal availability domain network, a failure at one availability domain within a region is unlikely to impact the availability of the others within the same region. fault domain is a grouping of hardware and infrastructure within an availability domain. Each availability domain contains three fault domains. Fault domains provide anti-affinity: they let you distribute your instances so that the instances are not on the same physical hardware within a single availability domain. A hardware failure or Compute hardware maintenance event that affects one fault domain does not affect instances in other fault domains. In addition, the physical hardware in a fault domain has independent and redundant power supplies, which prevents a failure in the power supply hardware within one fault domain from affecting other fault domains.
