Question 51
Question
You are designing a lab exercise for your team that has a large number of graphics with large file sizes. The application becomes unresponsive if the graphics are embedded in the application. You have uploaded the graphics to Oracle Cloud Infrastructure and only added the URL in the application.
You need to ensure these graphics are accessible without requiring any authentication for an extended period of time.
How can you achieve these requirements?
A. Create pre-authenticated requests (PAR) and specify 00:00:0000 as the expiration time.
B. Make the object storage bucket private and all objects public and use the URL found in the Object “Details”.
C. Make the object storage bucket public and use the URL found in the Object “Details”.
D. Create PARs and do not specify an expiration date.
Answer
C. Make the object storage bucket public and use the URL found in the Object “Details”.
Explanation
Pre-authenticated requests provide a way to let you access a bucket or an object without having your own credentials. For example, you can create a request that lets you upload backups to a bucket without owning API keys.
When you create a bucket, the bucket is considered a private bucket and the access to the bucket and bucket contents requires authentication and authorization. However, Object Storage supports anonymous, unauthenticated access to a bucket. You make a bucket public by enabling read access to the bucket.
Pre-authenticated requests have to select expiration date.
Question 52

Question 53
Question
You are the Cloud Architect of a company, and are designing a solution on Oracle Cloud Infrastructure where you want to have all your compute instances resistant to hardware failure.
Which two are recommended best practices to achieve the requirement on Oracle Cloud Infrastructure? (Choose two.)
A. Create a custom image of your system drive each time you change the image.
B. Attach block volumes from different Availability Domains to compute instances in different Availability Domains for high availability.
C. Design your system with redundant compute modes in different Availability Domains to support the failover capability.
D. Create backups of your block volumes that are associated with compute instances in different regions.
Answer
A. Create a custom image of your system drive each time you change the image.
C. Design your system with redundant compute modes in different Availability Domains to support the failover capability.
Explanation
System Resilience
Oracle Cloud Infrastructure runs on Oracle’s high-quality Sun servers. However, any hardware can experience a failure. Follow industry-wide hardware failure best practices to ensure the resilience of your solution. Some best practices include:
- Design your system with redundant compute nodes in different availability domains to support fail-over capability.
- Create a custom image of your system drive each time you change the image.
- Back up your data drives, or sync to spare drives, regularly.
- If you experience a hardware failure and have followed these practices, you can terminate the failed instance, launch your custom image to create a new instance, and then apply the backup data.

Question 54
Question
You are planning to deploy a multi-region web application in Oracle Cloud Infrastructure (OCI). You have customers in North America, Asia and Europe who will access the application.
What service is available in OCI to help you choose the regions the lowest latency to these markets?
A. Internet Intelligence
B. FastConnect
C. IPsec VPN
D. DNS Zone Management
Answer
A. Internet Intelligence
Question 55
Question
You must implement a backup solution for your Autonomous Data Warehouse (ADW) that will enable you to restore data as old as one year with a recovery point objective (RPO) of 10 days.
Which database backup strategy would you select?
A. Take weekly manual backups to supplement the automated backups and preserve them for 12 months.
B. Use the automated backups.
C. Take monthly manual backups to supplement the automated backups and preserve them for 12 months.
D. Take quarterly manual backups to supplement the automated backups and preserve them for 12 months.
Answer
B. Use the automated backups.
Explanation
Oracle Cloud Infrastructure automatically backs up your Autonomous Databases and retains these backups for
60 days. Automatic backups are weekly full backups and daily incremental backups. You can also create manual backups to supplement your automatic backups. Manual backups are stored in an Object Storage bucket that you create, and are retained for 60 days The retention period for manual backups is the same as automatic backups which is 60 days. So we cannot preserve the backup for 12 months

Question 56
Question
A customer wants to do development on-premise while leveraging services such as Java Cloud, Mobile Developer Cloud, and App Builder Services. The customer would also like to scale out the application, stretching from on-premises to the cloud by using a common API.
Which two Infrastructure options can the customer leverage to do this? (Choose two.)
A. Oracle Cloud at Customer
B. Oracle Cloud Infrastructure Classic
C. Oracle Cloud Ravello service
D. Oracle Cloud Infrastructure
Answer
A. Oracle Cloud at Customer
D. Oracle Cloud Infrastructure
Question 57
Question
For what business need should you use Database Cloud Service (DBCS) instead of Oracle database on a compute instance?
A. to bring your own license on a compute service
B. to lower license and infrastructure cost
C. to implement Oracle RAC for high availability
D. to build an Oracle database on a compute service
Answer
C. to implement Oracle RAC for high availability
Question 58
Question
Which two options are valid for loading data directly into Autonomous Data Warehouse (ADW)? (Choose two.)
A. Data Integrator
B. Data Pump
C. Data Transfer Service
D. SQL *Loader
Answer
B. Data Pump
D. SQL *Loader

Question 59
Question
Which statement is true about a pre-authenticated request in Oracle Cloud Infrastructure Object Storage?
A. You can create only 1, 000 pre-authenticated requests per bucket.
B. You can create a pre-authenticated request only for public buckets.
C. You cannot retire a pre-authenticated request before it expires.
D. You cannot extend the expiration date on a pre-authenticated request.
Answer
D. You cannot extend the expiration date on a pre-authenticated request.
Explanation
You can create an unlimited number of pre-authenticated requests. You can’t edit a pre-authenticated request. If you want to change user access options in response to changing requirements, you must create a new pre-authenticated request.
You can change a bucket’s access from public to private or from private to public. Changing the type of access doesn’t affect existing pre-authenticated requests. Existing pre-authenticated requests still work.

Question 60
Question
You need to create a high-performance shared file system and have been advised to use file storage service (FSS). You have logged into the Oracle Cloud Infrastructure console, created a file system, and followed the steps to mount the shared file system on your Linux instance. However, you are still unable to access the shared file system from your Linux instance.
What is the likely reason for this?
A.There are no security list rules for mount target traffic
B. There is no internet gateway (IGW) set up for mount target traffic
C. There is no Identity and Access Management (IAM) policies set up to allow you to access the mount target
D. There is no route in your virtual cloud network’s (VCN) route table for mount target traffic
Answer
A.There are no security list rules for mount target traffic
