NEW QUESTION 15

You are about to upload log file (5 TiB size) to Oracle Cloud Infrastructure object storage and have decided to use multipart upload capability for a more efficient and resilient upload.
Which two statements are true about multipart upload? (Choose two.)

• A. Individual object parts can be as small as 10 MiB or as large as 50 GiB
• B. While a multipart upload is still active, you cannot add parts even if the total number of parts is less than 10,000
• C. The maximum size for an uploaded object is 10 TiB
• D. You do not have to commit the upload after you have uploaded all the object parts

Answer: AC

Explanation:
With multipart upload, you split the object you want to upload into individual parts. Individual parts can be as large as 50 GiB or as small as 10 MiB. (Object Storage waives the minimum part size restriction for the last uploaded part.) Decide what part number you want to use for each part. Part numbers can range from 1 to 10,000. You do not need to assign contiguous numbers, but Object Storage constructs the object by ordering part numbers in ascending order.
The maximum size for an uploaded object is 10 TiB
While a multipart upload is still active, you can keep adding parts as long as the total number is less than 10,000.

NEW QUESTION 21

You are in the process of setting up a highly available student registration website on Oracle Cloud Infrastructure (OCI). You use a load balancer and a database service on OCI. You launch two compute instances each in a different subnet and add them to the back end set of a public load balancer. The load balancer is configured correctly and working. You then deploy the student registration application on these two compute instances. The application can communicate with the database service. However, when you type the URL of this student registration application in your browser, no web page appears.
What could be the cause?

• A. The security lists of the subnets on which the two instances are located do not have “allow” rules for port 80 and 443.
• B. The load balancer performed a health check on the application and found that compute instances were not in a healthy state and terminated the instances.
• C. The client requested https access to the application and the load balancer service does not support end-to-end SSL from the client to the listener to the back-end set.
• D. The Dynamic Routing Gateway is preventing the client traffic from your data center network from reaching the public IP of the load balancer.

NEW QUESTION 23

You have hired a new employee to run reports from the Autonomous Data Warehouse (ADW) and are not confident in their SQL writing ability.
Into which consumer group will you assign this individual to minimize the impact of their code?

• A. Lowest
• B. Medium
• C. Highest
• D. High
• E. Low

Answer: E

Explanation:
in ADW, The tnsnames.ora file provided with the credentials zip file contains three database service names identifiable as high, medium, and low. The predefined service names provide different levels of performance and concurrency for Autonomous Data Warehouse.
high: The High database service provides the highest level of resources to each SQL statement resulting in the highest performance, but supports the fewest number of concurrent SQL statements. Any SQL statement in this service can use all the CPU and IO resources in your database. The number of concurrent SQL statements that can be run in this service is 3, this number is independent of the number of OCPUs in your database.
medium: The Medium database service provides a lower level of resources to each SQL statement potentially resulting a lower level of performance, but supports more concurrent SQL statements. Any SQL statement in this service can use multiple CPU and IO resources in your database. The number of concurrent SQL statements that can be run in this service depends on the number of OCPUs in your database.
low: The Low database service provides the least level of resources to each SQL statement, but supports the most number of concurrent SQL statements. Any SQL statement in this service can use a single CPU and multiple IO resources in your database. The number of concurrent SQL statements that can be run in this service can be up to 300 times the number of OCPUs.
The predefined service names provide different levels of performance and concurrency for Autonomous DB Choose whichever database service offers the best balance of performance and concurrency.
Use the low database service name. to minimize the impact of their SQLs to by low consumer group

NEW QUESTION 24

You are deploying a highly available web application In Oracle Cloud Infrastructure and have decided to use a public load balancer. The back-end web servers will be distributed across all three availability domains (ADs).
How many subnets should you create to deliver a secure, highly available application?

• A. two subnets in total; one regional private subnet to host your back-end web servers and one regional public subnet to host your public load load balancer.
• B. two subnets in total; one regional public subnet to host your back-end web servers and one regional private subnet to host your public load load balancer.
• C. three subnets in total; one regional public subnet to host your back-end web servers and two AD specific private subnets to host your private load load balancer.
• D. one subnet in total; one regional private subnet to host your back-end web servers and your public load balancer.

Answer: A

Explanation:
To accept traffic from the internet, you create a public load balancer. The service assigns it a public IP address that serves as the entry point for incoming traffic. You can associate the public IP address with a friendly DNS name through any DNS vendor.
A public load balancer is regional in scope. If your region includes multiple availability domains, a public load balancer requires either a regional subnet (recommended) or two availability domain-specific
(AD-specific) subnets, each in a separate availability domain. With a regional subnet, the Load Balancing service creates a primary load balancer and a standby load balancer, each in a different availability
domain, to ensure accessibility even during an availability domain outage.
If you create a load balancer in
two AD-specific subnets, one subnet hosts the primary load balancer and the other hosts a standby load balancer. If the primary load balancer fails, the public IP address switches to the secondary load balancer. The service treats the two load balancers as equivalent and you cannot specify which one is "primary".
Whether you use regional or AD-specific subnets, each load balancer requires one private IP address from its host subnet. The Load Balancing service supplies a floating public IP address to the primary load balancer. The floating public IP address does not come from your backend subnets.
You cannot specify a private subnet for your public load balancer.
The backend servers (Compute instances) associated with a backend set can exist anywhere, as long as the associated network security groups (NSGs), security lists, and route tables allow the intended traffic flow. Oracle recommends that you create your load balancer in a regional subnet.
Oracle recommends that you distribute your backend servers across all availability domains within the region.
