Explanation
Oracle Cloud Infrastructure Marketplace is an online store that offers solutions specifically for customers of Oracle Cloud Infrastructure. In the Oracle CloudInfrastructure 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.
NEW QUESTION 17
Which capability can be used to protect against unexpected hardware or power supply failures within an Availability Domain?
- A. Compartments
- B. Fault Domains
- C. Power Distribution Units
- D. Top of Rack Switches
Answer: B
Explanation:
Fault domains can protect your application against unexpected hardware failures or outages caused by maintenance on the underlying computer hardware. Additionally, you can launch instances of all shapes within a fault domain. Oracle Cloud Infrastructure is typically designed with three availability domains per region, and each availability domain has three fault domains. When carrying out maintenance on the underlying computer hardware, Oracle Cloud Infrastructure ensures that only a single fault domain is impacted at one time to guarantee availability of your instances in the remaining fault domains.
Getting started is easy. When you create a new compute instance using the API, CLI or Console, you can specify the fault domain in which to place the instance. If you don't specify a fault domain, the instance will be distributed automatically in one of the three fault domains within that availability domain. Oracle Cloud Infrastructure makes a best-effort anti-affinity placement while optimizing for available capacity in the Availability Domain.

NEW QUESTION 20
A customer wants to use Oracle Cloud Infrastructure (OCI) storing 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?
- A. Object Storage (standard)
- B. Block Volume
- C. File Storage
- D. Archive Storage
Answer: A
Explanation:
Explanation
Oracle Cloud Infrastructure 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 maximizeperformance 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.
NEW QUESTION 21
What is the target time within which a given application must be restored after a disaster occurs?
- A. Elasticity
- B. RTO
- C. Fault Tolerant
- D. RPO
Answer: B
Explanation:
The RTO is the target time within which a given application must be restored after a disaster occurs.
Typically, the more critical the applications, the lower the RTO.
NEW QUESTION 22
Which three services integrate with Oracle Cloud Infrastructure (OCI) Key Management? (Choose all correct answers)
- A. Auto Scaling
- B. Functions
- C. Object Storage
- D. Identity and Access Management
- E. Block Volume
- F. File Storage
Answer: C,E,F
NEW QUESTION 23
___________________ is a fully-managed, scalable, andhighly available service that you can use to deploy your containerized applications to the cloud.
- A. Oracle Cloud Infrastructure Container Engine for Kubernetes
- B. Oracle Cloud Infrastructure Container Engine for Docker
- C. Oracle Cloud Infrastructure Container Engine for Containerization
- D. Oracle Cloud Infrastructure Container Engine for Deployment
Answer: A
Explanation:
Explanation
Oracle Cloud Infrastructure Container Engine for Kubernetes is a fully-managed, scalable, and highly available service that you can use to deploy your containerized applications to the cloud. Use Container Engine for Kubernetes (sometimes abbreviated to just OKE) when your development team wants to reliably build, deploy, and manage cloud-native applications. You specify the compute resources that your applications require, and Container Engine for Kubernetes provisions them on Oracle Cloud Infrastructure in an existing OCI tenancy.
You can access Container Engine for Kubernetes to define and create Kubernetes clusters using the Console and the RESTAPI. You can access the clusters you create using the Kubernetes command line (kubectl), the Kubernetes Dashboard, and the Kubernetes API.
Container Engine for Kubernetes is integrated with Oracle Cloud Infrastructure Identity and Access Management (IAM),which provides easy authentication with native Oracle Cloud Infrastructure identity functionality.

NEW QUESTION 27
Which two are enabled by Oracle Cloud Infrastructure Fault Domains?
- A. Protect against planned hardware maintenance
- B. Build replicated systems for disaster recovery
- C. To mitigate the risk of largescale events such as earthquakes
- D. To meet requirements for legal jurisdictions
- E. Protect against unexpected hardware or power supply failures
Answer: A,E
Explanation:
Explanation
A fault domain is a grouping of hardware and infrastructure within an availability domain. Each availabilitydomain 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.
Use fault domains to do the following things:
Protect against unexpected hardware failures or power supply failures.
Protect against plannedoutages because of Compute hardware maintenance.
We can use 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
