NEW QUESTION # 32
Your company has deployed a business critical application in Oracle Cloud Infrastructure. What should you do to ensure that your application has the highest level of resilience and availability?
- A. Deploy the application across multiple Virtual Cloud Networks
- B. Deploy the application across multiple Availability Domains and Fault Domains
- C. Deploy the application across multiple Regions and Availability Domains
- D. Deploy the application across multiple Availability Domains and Subnets
Answer: C
Explanation:
To design a high availability architecture, three key elements should be considered- redundancy, monitoring, and failover:
1) Redundancy means that multiple components can perform the same task. The problem of a single point of failure is eliminated because redundant components can take over a task performed by a component that has failed.
2) Monitoring means checking whether or not a component is working properly.
3) Failover is the process by which a secondary component becomes primary when the primary component fails.
The best practices introduced here focus on these three key elements. Although high availability can be achieved at many different levels, including the application level and the cloud infrastructure level, here we will focus on the cloud infrastructure level.
An Oracle Cloud Infrastructure region is a localized geographic area composed of one or more availability domains, each composed of three fault domains. High availability is ensured by a redundancy of fault domains within the availability domains.
An availability domain is one or more data centers located within a region. Availability domains are isolated from each other, fault tolerant, and unlikely to fail simultaneously. Because availability domains do not share physical infrastructure, such as power or cooling, or the internal availability domain network, a failure that impacts one availability domain is unlikely to impact the availability of others.
A fault domain is a grouping of hardware and infrastructure within an availability domain. Each availability domain contains three fault domains. Fault domains let you distribute your instances so that they are not on the same physical hardware within a single availability domain. As a result, an unexpected hardware failure or a Compute hardware maintenance that affects one fault domain does not affect instances in other fault domains. You can optionally specify the fault domain for a new instance at launch time, or you can let the system select one for you.
All the availability domains in a region are connected to each other by a low-latency, high bandwidth network. This predictable, encrypted interconnection between availability domains provides the building blocks for both high availability and disaster recovery.

NEW QUESTION # 37
Which statement is NOT true about compartments in Oracle Cloud infrastructure?
- A. Identity and Access Management (IAM) policies can be written to grant access to resources in specific compartments.
- B. Compartments are global resource.
- C. Compartments can be nested to create a hierarchy.
- D. Components provide a way to store and manage encryption keys and secrets.
Answer: D
Explanation:
Compartments do not provide a way to store and manage encryption keys and secrets in Oracle Cloud Infrastructure. Compartments are logical containers that help users organize and isolate their cloud resources. Compartments can be nested to create a hierarchy that reflects the structure of an organization or project. To store and manage encryption keys and secrets, users can use the Oracle Cloud Infrastructure Vault service, which is a fully managed service that provides centralized management of encryption keys, secrets, and certificates.

NEW QUESTION # 39
A customer wants to deploy a customized e commerce Web application using multiple virtual machines, block storage, databases, load balancer and web application firewall.
What cloud model can be used to host this application?
- A. Anything as a Service (XaaS)
- B. Infrastructure as a Service (IaaS)
- C. Software as a Service (SaaS)
- D. Platform as a Service (PaaS)
Answer: B
Explanation:
https://www.oracle.com/cloud/what-is-iaas/
What Is IaaS?
Infrastructure as a service (IaaS) is a type of cloud service model in which computing resources are hosted in the cloud. Businesses can use the IaaS model to shift some or all of their use of on-premises or colocated data center infrastructure to the cloud, where it is owned and managed by a cloud provider. These infrastructure elements can include compute, network, and storage hardware as well as other components and software.
In the IaaS model, the cloud provider owns and operates the hardware and software and also owns or leases the data center. When you have an IaaS solution, you rent the resources like compute or storage, provision them when needed, and pay for the resources your organization consumes. For some resources such as compute, you'll pay for the resources you use. For others such as storage, you'll pay for capacity.
How Does IaaS Work?
In a typical IaaS model, a business-which can be of any size-consumes services like compute, storage, and databases from a cloud provider. The cloud provider offers those services by hosting hardware and software in the cloud. The business will no longer need to purchase and manage its own equipment, or space to host the equipment, and the cost will shift to a pay-as-you-go model. When the business needs less, it pays for less. And when it grows, it can provision additional computing resources and other technologies in minutes.
In contrast, in a traditional on-premises scenario, a business manages and maintains its own data center. The business must invest in servers, storage, software, and other technologies, and hire an IT staff or contractors to purchase, manage, and upgrade all the equipment and licenses. The data center has to be built to meet peak demand, even though sometimes workloads decline and those resources stand idle. Conversely, if the business grows quickly, the IT department might struggle to keep up.

NEW QUESTION # 41
Which two should be considered when designing a fault tolerant solution in Oracle Cloud Infrastructure (OCI)?
- A. performing data integrity check when using OCI File Storage Service
- B. ensuring your solution components are distributed across OCI Fault Domains
- C. creating a manual cluster of compute instances
- D. writing custom scripts that will monitor your solution
- E. using multiple OCI Availability Domains (AD), where available, to deploy your solution
Answer: B,E
Explanation:
Creating a manual cluster of compute instances, and Writing custom scripts that will monitor your solution are not valid ways to ensure fault tolerance at all. Also, Performing Data Integrity check when using OCI File Storage Service is not valid since OCI takes care of it.
Therefore, we are left with:
1) Using multiple OCI Availibility Domains (AD), where available, to deploy your solution - Which is excellent because we have multiple AD's so that if one fails, we have a backup AD!
2) Ensuring your solution components are distributed across OCI Fault Domains - So that we can protect our deployment against unexpected power failures, AD failure etc.

You have an application that requires a shared file system. Which of the following services would you use?
- A. File Storage
- B. Archive Storage
- C. Block Volume
- D. Object Storage
Answer: A
Explanation:
Explanation
Oracle Cloud Infrastructure File Storage service provides a durable, scalable, secure, enterprise-grade network file system. You can connect to a File Storage service file system from any bare metal, virtual machine, or container instance in your Virtual Cloud Network (VCN). You can also access a file system from outside the VCN using Oracle Cloud Infrastructure FastConnect and Internet Protocol security (IPSec) virtual private network (VPN).
Large Compute clusters of thousands of instances can use the File Storage service for high-performance shared storage. Storage provisioning is fully managed and automatic as your use scales from a single byte to exabytes without upfront provisioning.
The File Storage service supports the Network File System version 3.0 (NFSv3) protocol. The service supports the Network Lock Manager (NLM) protocol for file locking functionality.
Oracle Cloud Infrastructure File Storage employs 5-way replicated storage, located in different fault domains, to provide redundancy for resilient data protection. Data is protected with erasure encoding.
The File Storage service uses the "eventual overwrite" method of data eradication. Files are created in the file system with a unique encryption key. When you delete a single file, its associated encryption key is eradicated, making the file inaccessible. When you delete an entire file system, the file system is marked as inaccessible. The service systematically traverses deleted files and file systems, frees all the used space, and eradicates all residual files.
Use the File Storage service when your application or workload includes big data and analytics, media processing, or content management, and you require Portable Operating System Interface (POSIX)-compliant file system access semantics and concurrently accessible storage. The File Storage service is designed to meet the needs of applications and users that need an enterprise file system across a wide range of use cases, including the following:

NEW QUESTION # 50
Which TWO statements are true regarding Oracle Cloud Infrastructure (OCI) Regions?
(Choose al correct answers)
- A. Some regions provide multiple subregions.
- B. Some regions provide multiple availability domains.
- C. Some regions provide a single availability domain.
- D. Some regions provide a single fault domain.
- E. Some regions only provide test/dev environments.
Answer: B,C
Explanation:
These statements are true regarding OCI regions. A region is a localized geographic area that hosts one or more availability domains. An availability domain is one or more data centers that host OCI resources such as compute instances, block volumes, and subnets. Availability domains are isolated from each other, fault tolerant, and very unlikely to fail simultaneously1 Some regions provide multiple availability domains, while some regions provide a single availability domain. The number of availability domains per region varies depending on the region type and the customer demand. You can check the list of regions and their availability domains here: 2 Commercial regions: These are the standard regions that are available to all customers and offer a wide range of OCI services and features. Commercial regions can have one, two, or three availability domains per region.
Government regions: These are the regions that are dedicated to US government customers and meet specific compliance and security requirements. Government regions can have one or two availability domains per region.
Dedicated regions: These are the regions that are deployed within a customer's data center and provide a fully managed OCI environment that is consistent with the public cloud regions. Dedicated regions can have one or two availability domains per region.
The other statements are false regarding OCI regions. There is no concept of subregions in OCI. A region is composed of one or more availability domains, not subregions1 Regions do not only provide test/dev environments. Regions can host any type of workload or application, whether it is for production, development, testing, or disaster recovery purposes. Regions offer different performance levels, service levels, and pricing options to suit different customer needs and use cases1 Regions do not provide a single fault domain. A fault domain is a grouping of hardware and infrastructure within an availability domain that is designed to be isolated from failures in other fault domains. Fault domains let you distribute your instances so that they are not on the same physical hardware within a single availability domain. Each availability domain has three fault domains, regardless of the number of availability domains in a region3
