  https://docs.cloud.oracle.com/iaas/Content/Balance/Reference/sessionpersistence.htm The Load Balancing service considers a server marked drain available for existing persisted sessions. New requests that are not part of an existing

  persisted session are not sent to that server.

• Question 2:

  Which two statements about the Oracle File Storage Service (FSS) Security are accurate? (Choose two.)

  A. Oracle IAM controls which filesystems are mountable by which instances.
  B. Security lists can be used as a virtual firewall to prevent an instance from mounting an FSS mount target within a subnet.
  C. Encryption of file storage in FSS is optional.
  D. Data in transit to an FSS mount target is encrypted.
  E. FSS leverages UNIX user group and permission checking for file access security.
  D. Data in transit to an FSS mount target is encrypted.
  E. FSS leverages UNIX user group and permission checking for file access security.

  All data is encrypted at rest. and In-transit encryption provides a way to secure your data between instances and mounted file systems using TLS v. 1.2 (Transport Layer Security) encryption. File Storage service supports the AUTH_UNIX style of authentication and permission checking for remote NFS client requests.

• Question 3:

  You want an instance in your compartment to make API calls to other services within Oracle Cloud Infrastructure without storing credentials in a configuration file. What do you need to do?

  A. No action is required. By default, all VM instances are created with an Instance Principal.
  B. Instances cannot access services outside their compartment.
  C. VM instances are treated as users. Create a user and assign the user to that VM instance.
  D. Create appropriate matching rules in the Dynamic Group to create an Instance Principal.
  D. Create appropriate matching rules in the Dynamic Group to create an Instance Principal.

• Question 4:

  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
  A. Oracle Cloud at Customer
  D. Oracle Cloud Infrastructure

• Question 5:

  You have an external facing web server running in the Oracle Cloud Infrastructure (OCI) London region. You are notified that customers in North America and Australia are facing high latency while connecting to your web server. Which services are available on OCI that can help you get current latency statistics to your web server from these markets?

  A. Use DNS Zone Management service to check latency over that connection
  B. Setup an IPsec VPN with customers in those markets and check latency over that connection
  C. Use the Internet Intelligence tool. Run tests using the web server's public IP address and review traceroute details from different vantage points
  D. Setup a FastConnect with customers in those markets and check latency over that connection
  C. Use the Internet Intelligence tool. Run tests using the web server's public IP address and review traceroute details from different vantage points

  The second tool, OCI IP Troubleshooting, helps troubleshoot issues with public facing IP addresses. This feature is also part of our Internet Intelligence toolset, providing analytical insight to help network operations teams reduce the time it takes to troubleshoot an issue by providing awareness of availability and latency across the Internet.

• Question 6:

  Which storage would you use if your big data workload requires shared access and an NFS based interface?

  A. File Storage
  B. Storage Software Cloud Appliance
  C. Object Storage
  D. Archive Storage
  E. Block Volume
  A. File Storage

  References:

  https://docs.cloud.oracle.com/iaas/Content/File/Concepts/filestorageoverview.htm The File Storage service is designed to meet the needs of applications and users that need an enterprise file system across a wide range of use cases,

  including the following:

  General Purpose File Storage: Access to an unlimited pool of file systems to manage growth of structured and unstructured data.

  Big Data and Analytics: Run analytic workloads and use shared file systems to store persistent data. Lift and Shift of Enterprise Applications: Migrate existing Oracle applications that need NFS storage, such as Oracle E-Business Suite and

  PeopleSoft.

  Databases and Transactional Applications: Run test and development workloads with Oracle, MySQL, or other databases.

  Backups, Business Continuity, and Disaster Recovery: Host a secondary copy of relevant file systems from on premises to the cloud for backup and disaster recovery purposes. MicroServices and Docker: Deliver stateful persistence for

  containers. Easily scale as your container- based environments grow.

• Question 7:

  At the end of a terraform apply operation, what is the default output?

  A. nothing by default
  B. statistics about what was added, changed, and destroyed
  C. the entire state file
  D. statistics about what was added, changed, and destroyed, and the values of outputs
  D. statistics about what was added, changed, and destroyed, and the values of outputs

• Question 8:

  Which three actions are required to configure a highly available and secure hybrid network between Oracle Cloud and your data center? (Choose three.)

  A. Define a non-overlapping IP Address Space between the data center and the cloud.
  B. Configure each of the CPEs to leverage each of the IPSec Tunnels created by the connection process.
  C. Create two or more CPEs that map to the private IP addresses of the customer routers used in the IPSec VPN Tunnel.
  D. Define a default route table entry for the VCN that directs all traffic to the data center network to a single DRG.
  E. Create dynamic routing gateways in more than one AD within your region.
  A. Define a non-overlapping IP Address Space between the data center and the cloud.
  B. Configure each of the CPEs to leverage each of the IPSec Tunnels created by the connection process.
  C. Create two or more CPEs that map to the private IP addresses of the customer routers used in the IPSec VPN Tunnel.
