You have an analytics workload that requires a shared file system to store persistent dat a. Which Oracle Cloud Infrastructure (OCI) Storage service is most suited for this requirement?
Correct Answer: B
Question 42
A customer wants a dedicated and secure connection to their on-premises data center from their Oracle Cloud Infrastructure (OCI) resources. Which TWO OCI services can be used? (Choose all correct answers)
Correct Answer: A,D
Question 43
You want to leverage a managed Real Application Cluster (RAC) offering in Oracle Cloud Infrastructure. which OCI Managed database service would you choose?
Correct Answer: B
There are 2 types of DB systems on virtual machines: A 1-node VM DB system consists of one VM. A 2-node VM DB system consists of two VMs clustered with RAC enabled. Reference: https://docs.cloud.oracle.com/en-us/iaas/Content/Database/Concepts/overview.htm Oracle Cloud Infrastructure offers single-node DB systems on either bare metal or virtual machines, and 2-node RAC DB systems on virtual machines. If you need to provision a DB system for development or testing purposes, then a special fast provisioning single-node virtual machine system is available. You can manage these systems by using the Console, the API, the Oracle Cloud Infrastructure CLI, the Database CLI (DBCLI), Enterprise Manager, Enterprise Manager Express, or SQL Developer.
Question 44
After Signing up for a new Oracle cloud Infrastructure tenancy, what would you subscribe to in order to deploy infrastructure and services in different parts of the world?
Correct Answer: D
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. Oracle is adding multiple cloud regions around the world to provide local access to cloud resources for our customers. To accomplish this quickly, we've chosen to launch regions in new geographies with one availability domain. As regions require expansion, we have the option to add capacity to existing availability domains, to add additional availability domains to an existing region, or to build a new region. The expansion approach in a particular scenario is based on customer requirements as well as considerations of regional demand patterns and resource availability. For any region with one availability domain, a second availability domain or region in the same country or geo-political area will be made available within a year to enable further options for disaster recovery that support customer requirements for data residency where they exist.
Question 45
Which Oracle Cloud Infrastructure storage service can provide a shared file system across multiple compute instances?
Correct Answer: A
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.
