Oracle 1Z0-1085-22 Online Questions & Answers

• Question 91:

  Which capability can be used to protect against unexpected hardware or power supply failures within an availability domain?

  A. Fault Domains
  B. Compartments
  C. Top of Rack Switches
  D. Power Distribution Units
  A. Fault Domains

  ---

  Explanation/Reference:

  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.

  Usually fault domains to do the following things:

  1) Protect against unexpected hardware failures or power supply failures.

  2) Protect against planned outages because of Compute hardware maintenance.

  B. Each Availability Domain has three Fault Domains.

  Explanation/Reference:

  Oracle Cloud Infrastructure 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. Most Oracle Cloud Infrastructure resources are either region-specific, such as a virtual cloud network, or availability domain-specific, such as a compute instance. Traffic between availability domains and between regions is encrypted. 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. The availability domains within the same region are connected to each other by a low latency, high bandwidth network, which makes it possible for you to provide high-availability connectivity to the internet and on-premises, and to build replicated systems in multiple availability domains for both high-availability and disaster recovery. 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.

• Question 93:

  Which capability enables you to search, purchase, and start using software in your Oracle Cloud Infrastructure (OCI) tenancy?

  A. OCI Marketplace
  B. OCI OS Management
  C. OCI Resource Manager
  D. OCI Registry
  A. OCI Marketplace

  ---

  Explanation/Reference:

  Oracle Cloud Infrastructure Marketplace is an online store that offers solutions specifically for customers of Oracle Cloud Infrastructure. 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 that determine 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.

• Question 94:

  Which Oracle Cloud Infrastructure service allows you to run code without provisioning any underlying infrastructure resources?

  A. Compute service
  B. Storage Gateway
  C. Oracle Container Engine for Kubernetes
  D. Oracle Functions
  D. Oracle Functions

  ---

  Explanation/Reference:

  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. Oracle Functions simply ensures your app is highly-available, scalable, secure, and monitored. With Oracle Functions, you can write code in Java, Python, Node, Go, and Ruby (and for advanced use cases, bring your own Dockerfile, and Graal VM). You can then deploy your code, call it directly or trigger it in response to events, and get billed only for the resources consumed during the execution.

• Question 95:

  Which is NOT covered by Oracle Cloud Infrastructure (OCI) Service Level Agreement (SLA)?

  A. Manageability
  B. Performance
  C. Reliability
  D. Availability
  C. Reliability

  ---

  Explanation/Reference:

  https://www.oracle.com/assets/paas-iaas-pub-cld-srvs-pillar-4021422.pdf Enterprises demand more than just availability from their cloud infrastructure. Mission-critical workloads also require consistent performance, and the ability to manage, monitor, and modify resources running in the cloud at any time. Only Oracle offers end-to-end SLAs covering performance, availability, manageability of services.

• Question 96:

  Which service level agreement type is NOT offered by Oracle Cloud Infrastructure Compute service?

  A. Data Plane
  B. Performance
  C. Application Plane
  D. Control Plane
  C. Application Plane

  ---

  Explanation/Reference:

  Oracle offers several different service level agreements as defined in this section (Service Level Agreements).Service level agreements range from least restrictive (data plane) to more restrictive (control plane) to most restrictive

  (performance).

• Question 99:

  Which Oracle Cloud Infrastructure service leverages Terraform to configure infrastructure as code?

  A. Resource Manager
  B. Events
  C. Compartment Explorer
  D. Oracle Functions
  A. Resource Manager

  ---

  Explanation/Reference:

  Resource Manager is an Oracle Cloud Infrastructure service that allows you to automate the process of provisioning your Oracle Cloud Infrastructure resources. Using Terraform, Resource Manager helps you install, configure, and manage resources through the "infrastructure-as-code" model. A Terraform configuration codifies your infrastructure in declarative configuration files. Resource Manager allows you to share and manage infrastructure configurations and state files across multiple teams and platforms. This infrastructure management can't be done with local Terraform installations and Oracle Terraform modules alone. For more information about the Oracle Cloud Infrastructure Terraform provider, see Terraform Provider. For a general introduction to Terraform and the "infrastructure-as-code" model, see https://www.terraform.io.
