You have mission critical application which requires to be globally available at all time. 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. According to standard security model which 2 are a customer's responsibilities in OCI? - Physical Security of OCI data center facilities - Object Storage Data Security - Virtual Machine Hypervisor - Customer Data - Local data persistence - ✔✔Customer Data & Object Storage Data SecurityWhich 3 services integrate with OCI Key Management? - File Storage - Auto Scaling - Identity and Access Management - Object Storage - Block Volume - Functions - ✔✔- 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. Which OCI service allows you to run code without provisioning any underlying infrastructure resources (such as virtual machines) ? - Compute Service - Storage Gateway - Oracle Container Engine for Kubernetes- Oracle Function - ✔✔- Oracle Function Explanation Oracle Functions is a fully managed, multi-tenant, highly scalable, on-demand, Functions-as- a-Service platform. It is built on enterprise-grade Oracle Cloud Infrastructure and powered by the Fn Project open source engine. Use Oracle Functions (sometimes abbreviated to just Functions) when you want to focus on writing code to meet business needs. The serverless and elastic architecture of Oracle Functions means there's no infrastructure administration or software administration for you to perform. You don't provision or maintain compute instances, and operating system software patches and upgrades are applied automatically. Which 2 OCI resources can be used to group/categorize expenses? - Tags - Users - Policies - Compartments - Groups - ✔✔- Tags - Compartments Which statement about OCI shared security model is true? - You are responsible for managing security control within the physical OCI network. - You are not responsible for any aspect of security in OCI. - You are responsible for securing all data that you place in OCI - You are responsible for securing the hypervisor within OCI Compute Service. - ✔✔You are responsible for securing all data that you place in OCI Which 3 components are part of OCI Identity And Access Management service ?

Which capability can be used to protect against unexpected hardware or power supply failures within an availability domain? - Fault Domain - Compartments - Lot of back switches - Power Distribution Unit - ✔✔- Fault Domain ExplanationA 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.

Which statement accurately describes an OCI Region? - Each Availability Domain has a single Fault Domain - Each Availability Domain has three Fault Domains - Each Fault Domain has multiple available domain - Each region has a single Fault Domain. - ✔✔- Each Availability Domain has three Fault Domains Explanation OCI is hosted in regions and availability domains. A region is a localized geographic area, and an availability domain is one or more data centers located within a region. A region is composed of one or more availability domains. Each availability domain contains three fault domains. A company has deployed an e-commerce web application with OCI. What should they do to manage that the application has the highest level of resilience? - Deploy the application across multiple Virtual Cloud Networks. - Deploy the application across multiple availability domains and subnets. - Deploy the application across multiple availability domains and Fault Domains - Deploy the application across multiple Regions and Availability Domain - ✔✔- Deploy the application across multiple Regions and Availability Domain Explanation for highest level of resilience you can deploy the application between regions and distribute on availability domain and fault domains 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 capability enables you to search, purchase and start using software in your OCI tenancy? - OCI Region - OCI Marketplace - OCI OS Management - OCI Resource Manager - ✔✔- OCI Marketplace Explanation OCI Marketplace is an online store that offers solutions specifically for customers of OCI In the Oracle Cloud Infrastructure Marketplace catalog, you can find listings for two types of solutions from Oracle and trusted partners: images and stacks. These listing types include different categories of applications. Also, some listings are free and others require payment.Images are templates of virtual hard drives thatdetermine the operating system and software to run on an instance. You can deploy image listings on an Oracle Cloud Infrastructure Compute instance. Marketplace also offers stack listings. Stacks represent definitions of groups of Oracle Cloud Infrastructure resources that you can act on as a group. Each stack has a configuration consisting of one or more declarative configuration files. With an image or a stack, you have a customized, more streamlined way of getting started with a publisher's software. A customer wants to deploy an e-commerce web application using multiple virtual machines, block storage, databases , load balancer and web application firewall. Which cloud method can be used to host that application? - Anything as a Service - Platform as a Service - Infrastructure as a Service - Software as a Service - ✔✔- Infrastructure as a Service Which OCI service leverages Terraform to configure infrastructure as a code? - Resource Manager - Compartment Trigger - Events - Oracle Function - ✔✔- Resource Manager Explanation quick 2 min video about Resource Manager - https://www [Show More]
