• Question 111:

  For a compute instance that is launched in a private subnet in a Virtual Cloud Network (VCN), which action needs to be performed to connect to the Internet, assuming that the required security list is properly set up?

  A. Assign a Public IP address to the compute instance.
  B. Create and configure Network Address Translation (NAT) in a public subnet and route all traffic to it.

  D. Create a default route entry in the route table to forward all traffic to the Internet gateway.

• Question 112:

  You have been notified of an application failure indicating that one or more of the Oracle Cloud Infrastructure (OCI) resources have become unavailable. After scanning the Compute and Database consoles, you notice that one of the DB Systems is missing. What would you do to identify the reason for this missing resource?

  A. Navigate to the Audit console and search the previous 24 hours for all DELETE request actions to get a list of any resource that was deleted in the past 24 hours.
  B. Navigate to the Audit console and search the previous 24 hours for all the GET request actions to get a list of every event that occurred in the past 24 hours.
  C. View the service limits associated with your account to ensure that you have not exceeded the allowable number of DB Systems in your tenancy.
  D. Create a serial console connection to the DB System that does not appear in the management console. Connect to the serial console connection, and then review the system logs under /var/log/messages.
  A. Navigate to the Audit console and search the previous 24 hours for all DELETE request actions to get a list of any resource that was deleted in the past 24 hours.

  You can filter results by request actions to zero in on only the events with operations that interest you. For example, say that you only want to know about instances that were deleted during a specific time frame. Select a delete request action filter to see only the events with delete operations Reference: https://docs.cloud.oracle.com/en-us/iaas/Content/GSG/Tasks/usingaudit.htm

• Question 113:

  Which statement is true about Oracle Cloud Infrastructure Object Storage Service?

  A. An Archive Object Storage tier bucket can be upgraded to the Standard Object Storage tier.
  B. You cannot directly download an object from an Archive Object Storage bucket.
  C. An existing Standard Object Storage tier bucket can be downgraded to the Archive Object Storage tier.
  D. Data retrieval in Archive Object Storage is instantaneous.
  B. You cannot directly download an object from an Archive Object Storage bucket.

• Question 114:

  You have an Oracle Cloud Infrastructure (OCI) load balancer distributing traffic via an evenly- weighted round robin policy to your back-end web servers. You notice that one of your web servers is receiving more traffic than other web servers. How can you resolve this to make sure traffic is evenly distributed across all back-end webservers?

  A. Disable cookie-based session persistence on your backend set.
  B. Change kee
  C. Disable SSL configuration associated with your backend set.
  D. Create separate listeners for each backend web server.
  D. Create separate listeners for each backend web server.

• Question 115:

  In Oracle Cloud Infrastructure Container Engine for Kubernetes (OKE), what does a Replica Set do?

  A. It provides declarative updates for Pods.
  B. It maintains a stable set of replica Pods running at any given time.
  C. It ensures that all Nodes run a copy of a Pod.
  D. It exposes an application running on a set of Pods.
  D. It exposes an application running on a set of Pods.

• Question 116:

  Which is a customer's responsibility on an Oracle Cloud Infrastructure database?

  A. patching the database and OS
  B. creating the first default database on the DBCS server
  C. creating an ASM diskgroup for data file or temp file storage
  D. installing the operating system (OS), Grid Infrastructure, and database software
  A. patching the database and OS

  ---

  On autonomous there's no patching needed. But on the regular DB Cloud services you need to patch the DB and the OS. During the creation on the OCDB the first DB is created automatically Oracle automatically takes care of Operating system Installation/Configuration, Grid Infrastructure, ASM diskgroup Creation/Configuration , and database software Installation and first database on the DB System. that's all when Creating DB Systems. and then the customer responsible to apply the patches to the database and OS

• Question 117:

  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
  C. to implement Oracle RAC for high availability

• Question 118:

  You need to transfer over 12 TB of data from on-premises to your cloud account. You started copying this data over the internet and noticed that it will take too long to complete. Without increasing the costs of your subscription, what is the recommended way to send this amount of data to your cloud account?

  A. Use Data Transfer Service to send your data.
  B. Split the data into multiple parts and use the multipart tool.
  C. Use a 10 GB FastConnect line to send the data.
  D. Send the data over a VPN IPsec tunnel.
  E. Compress the data and use the multipart tool.
  A. Use Data Transfer Service to send your data.

  Overview of Data Transfer Service

  Oracle offers offline data transfer solutions that let you migrate data to Oracle Cloud Infrastructure. Moving data over the public internet is not always feasible due to high network costs, unreliable network connectivity, long transfer times, and

  security concerns. Our transfer solutions address these pain points, are easy to use, and provide significantly faster data upload compared to over-the- wire data transfer.

• Question 119:

  Where are DB Systems backups stored by default?

  A. ASM disk group
  B. locally attached NVMe on virtual machine
  C. block volume
  D. object storage on Oracle Cloud Infrastructure
  D. object storage on Oracle Cloud Infrastructure

• Question 120:

  Which two options are true for Autonomous Transaction Processing (ATP) database? (Choose two.)

  A. You can add/remove Diskgroup in ATP
  B. You can scale storage up or down in ATP
  C. You can scale CPU up or down in ATP
  D. You can add more Pluggable Database for consolidating multiple databases in ATP
  E. You can add new ORACLE_HOME for bringing older versions of on-premises databases to ATP
  B. You can scale storage up or down in ATP
  C. You can scale CPU up or down in ATP

  You can scale up/down your Autonomous Database to scale both in terms of compute and storage only when needed, allows people to pay per use.

  Oracle allows you to scale compute and storage independently, no need to do it together. these scaling activities fully online (no downtime required) in Details page Autonomous Database click Scale Up/Down. Click on arrow to select a value

  for CPU Core Count or Storage (TB).

  Or Select auto scaling to allow the system to automatically use up to three times more CPU and IO resources to meet workload demand, compared to the database operating with auto scaling disabled.
