You are working on the migration of the web application infrastructure of your company from on-premises to Oracle Cloud Infrastructure. You need to ensure that the DNS cache entries of external clients will not direct them to the on-premises infrastructure after switching to the new infrastructure.
Which of the following options will minimize this problem?
A startup company is looking for a solution for processing of data transmitted by the IOT devices fitted to transport vehicles that carry frozen foods. The data should be consumed and processed in real time. The processed data should be archived to OCI Object Storage bucket. and use Autonomous Data warehouse (ADW) to handle analytics.
Which architecture will help you meet this requirement?
Real-time processing of high-volume streams of data
- OCI Streaming service provides a fully managed, scalable, durable storage option for continuous, highvolume
streams of data that you can consume and process in real-time
- Use cases
Log and Event data collection
Web/Mobile activity data ingestion
IoT Data streaming for processing and alerts
Messaging: use streaming to decouple components of large systems
- Oracle managed service with REST APIs (Create, Put, Get, Delete)
- Integrated Monitoring
A cloud consultant is working on a implementation project on Oracle Cloud Infrastructure (OCI). As part of the compliance requirements, the objects placed in OCI Object Storage should be automatically archived first and then deleted. He is testing a lifecycle policy on Object Storage and created a policy as below:
What will happen after this policy is applied?
You are a solutions architect for a global health care company which has numerous data centers around the globe. Due to the ever growing data that your company is storing, you were Instructed to set up a durable, cost effective solution to archive you data from your existing on-premises tape based backup Infrastructure to Oracle Cloud Infrastructure (OCI).
What is the most-effective mechanism to Implement this requirement?
Oracle Cloud Infrastructure offers two distinct storage tiers for you to store your unstructured data. Use the Object Storage Standard tier for data to which you need fast, immediate, and frequent access. Use the Archive Storage service's Archive tier for data that you access infrequently, but which must be preserved for long periods of time. Both storage tiers use the same manageable resources (for example, objects and buckets). The difference is that when you upload a file to Archive Storage, the object is immediately archived. Before you can access an archived object, you must first restore the object to the Standard tier.
you can use Storage Gateway to move files to Oracle Cloud Infrastructure Archive Storage as a cost effective backup solution. You can move individual files and compressed or uncompressed ZIP or TAR
archives. Storing secondary copies of data is an ideal use case for Storage Gateway.
An OCI Architect is working on a solution consisting of analysis of data from clinical trials of a pharmaceutical company. The data is being stored in OCI Autonomous Data Warehouse (ADW) having 8 CPU Cores and 70 TB of storage. The architect is planning to setup autoscaling to respond to dynamic changes in the workload.
Which of the following needs to be considered while configuring auto scaling? Choose two
Explanation
Auto scaling is enabled by default when you create an Autonomous Database instance or you can use Scale
Up/Down on the Oracle Cloud Infrastructure console to enable or disable auto scaling.
With auto scaling enabled the database can use up to three times more CPU and IO resources than specified
by the number of OCPUs currently shown in the Scale Up/Down dialog. When auto scaling is enabled, if
your workload requires additional CPU and IO resources the database automatically uses the resources
without any manual intervention required.
Enabling auto scaling does not change the concurrency and parallelism settings for the predefined services
IO throughput depends on the number of CPUs you provision and scales linearly with the number of CPUs.
