• Question 153:

  You currently manage an e-commerce application that utilizes 25 identical compute resources to handle customer traffic. The stakeholders have asked you to create another 25 identical compute resources in order to deploy and test a new version of the software?

  A. Create a custom image from 1 of the 25 servers. Use this custom image to provision 25 more servers
  B. Create a manual backup of each boot volume belonging to the 25 servers. Restore each backup to create 25 new boot volumes, from which you will provision 25 more servers
  C. Provision a new server and configure it to be identical to the first 25. Create a custom image from the new server, then use the custom image to provision 24 more servers
  D. Clone the boot volume of 1 of the 25 servers. Use the boot volume clone to provision 25 more servers
  A. Create a custom image from 1 of the 25 servers. Use this custom image to provision 25 more servers

  B. Private and Public subnets cannot reside in the same Availability Domain for a given VCN.
  C. Subnets can have their IP addresses overlap with other subnets in another network for a given VCN.
  D. Instances obtain their private IP and the associated security list from their subnets.
  A. You can have multiple subnets in an Availability Domain for a given VCN.

• Question 156:

  A new employee has just started working for your company. You create an Oracle Cloud Infrastructure user account for this employee, following which they are able to log in, but still cannot create any resources. What should you do to resolve this?

  A. Send the employee API Signing Keys to log in.
  B. Delete the account and create another one.
  C. Make sure that the employee is logging in to the Oracle Cloud Infrastructure account from your corporate network only.
  D. Add the employee to a group with policies to grant access to relevant resources.
  D. Add the employee to a group with policies to grant access to relevant resources.

• Question 157:

  Which two are true for achieving High Availability on Oracle Cloud Infrastructure? (Choose two.)

  A. Store your database across multiple regions so that half of the data resides in one region and the other half resides in another region.
  B. Attach your block volume form Availability Domain 1 to a compute instance in Availability Domain 2 (and vice versa) so that they are highly available.
  C. Configure your database to have Data Guard in another Availability Domain in Sync mode within a region.
  D. Store your database files on Object Storage so that they are available in all Availability Domains in all regions.
  E. Distribute your application servers across all Availability Domains within a region.
  C. Configure your database to have Data Guard in another Availability Domain in Sync mode within a region.
  E. Distribute your application servers across all Availability Domains within a region.

• Question 158:

  You are a network architect of an application running on Oracle Cloud Infrastructure (OCI). Your security team has informed you about a security patch that needs to be applied immediately to one of the backend web servers. What should you do to ensure that the OCI load balancer does not forward traffic to this backend server during maintenance?

  A. Drain all existing connections to this backend server and mark the backend web server offline
  B. Create another OCI load balancer for the backend web servers, which are active and handling traffic
  C. Edit the security list associated with the subnet to avoid traffic connectivity to this backend serve
  D. Stop the load balancer for maintenance and restart the load balancer after the maintenance is finished
  A. Drain all existing connections to this backend server and mark the backend web server offline

  ---

  A load balancer improves resource utilization, facilitates scaling, and helps ensure high availability. You can configure multiple load balancing policies and application-specific health checks to ensure that the load balancer directs traffic only to healthy instances. The load balancer can reduce your maintenance window by draining traffic from an unhealthy application server before you remove it from service for maintenance. 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. Edit Drain State: Opens a dialog box in which you can change the drain state. If you set the server's drain status to true, the load balancer stops forwarding new TCP connections and new non-sticky HTTP requests to this backend server. This setting allows an administrator to take the server out of rotation for maintenance purposes.

  e. Edit Offline State: Opens a dialog box in which you can change the offline status.

  If you set the server's offline status to true, the load balance forwards no ingress traffic to this backend server.

• Question 159:

  Which two options are available within the service console of Autonomous Transaction Processing?

  A. Monitor the health of the database server including CPU, memory and query performance
  B. Configure resource management rules and reset the admin password
  C. Perform a manual backup of the ATP database
  D. Fine tune a long running query using optimizer hints
  A. Monitor the health of the database server including CPU, memory and query performance
  B. Configure resource management rules and reset the admin password

• Question 160:

  Which statement is true about Data Guard Implementation in DB systems?

  A. Both DB systems must be in the same compartment, and they must be the same shape
  B. You can define the backup window and set custom backup retention period for the automatic database backup schedule.
  C. You cannot manage Oracle database initialization parameters at a global level.
  D. You cannot manage the database as sys/sysdba.
  A. Both DB systems must be in the same compartment, and they must be the same shape

  ---

  An Oracle Data Guard implementation requires two DB systems, one containing the primary database and one containing the standby database. When you enable Oracle Data Guard for a virtual machine DB system database, a new DB

  system with the standby database is created and associated with the primary database. For a bare metal DB system, the DB system with the database that you want to use as the standby must already exist before you enable Oracle Data

  Guard.

  Requirement details are as follows:

  -Both DB systems must be in the same compartment.

  -

  The DB systems must be the same shape type (for example, if the shape of the primary database is a virtual machine, then the shape of the standby database can be any other virtual machine shape).

  -

  If your primary and standby databases are in different regions, then you must peer the virtual cloud networks (VCNs) for each database. See Remote VCN Peering (Across Regions).

  -

  Configure the security list ingress and egress rules for the subnets of both DB systems in the Oracle Data Guard association to enable TCP traffic to move between the applicable ports. Ensure that the rules you create are stateful (the default).
