  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 82:

  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.

• Question 83:

  You have an application deployed in Oracle Cloud Infrastructure running only in the Phoenix region. You were asked to create a disaster recovery (DR) plan that will protect against the loss of critical dat

  A. The DR site must be at least 500 miles from your primary site and data transfer between the two sites must not traverse the public Internet. Which is the recommended disaster recovery plan?
  B. Create a new virtual cloud network (VCN) in the Phoenix region and create a subnet in one availability domain (AD) that is not currently being used by your production systems. Establish VCN peering between the production and DR sites.
  C. Create a DR environment in Ashburn. Associate a DRG with the VCN in each region and create a remote peering connection between the two VCNs.
  D. Create a DR environment in Ashburn and provision a FastConnect virtual circuit using DRG between the regions.
  E. Create a DR environment in Ashburn. Associate a dynamic routing gateway (DRG) with the VCN in each region and configure an IPsec VPN connection between the two regions.
  B. Create a new virtual cloud network (VCN) in the Phoenix region and create a subnet in one availability domain (AD) that is not currently being used by your production systems. Establish VCN peering between the production and DR sites.

  ---

  Remote VCN peering is the process of connecting two VCNs in different regions (but the same tenancy ). The peering allows the VCNs' resources to communicate using private IP addresses without routing the traffic over the internet or

  through your on-premises network. Without peering, a given VCN would need an internet gateway and public IP addresses for the instances that need to communicate with another VCN in a different region.

  At a high level, the Networking service components required for a remote peering include:

  -

  Two VCNs with non-overlapping CIDRs, in different regions that support remote peering. The VCNs must be in the same tenancy.

  -

  A dynamic routing gateway (DRG) attached to each VCN in the peering relationship. Your VCN already has a DRG if you're using an IPSec VPN or an Oracle Cloud Infrastructure FastConnect private virtual circuit.

  A remote peering connection (RPC) on each DRG in the peering relationship.

  A connection between those two RPCs.

  Supporting route rules to enable traffic to flow over the connection, and only to and from select subnets in the respective VCNs (if desired).

  Supporting security rules to control the types of traffic allowed to and from the instances in the subnets that need to communicate with the other VCN.

  

• Question 84:

  Where is the tenancy Oracle Cloud Identifier (OCID) located?

  A. given by support on account creation
  B. at the bottom of every console page
  C. on the Identity ?Users page
  D. contained within the compartment OCID
  D. contained within the compartment OCID

  ---

  Identity > Compartments >(The root Compartment of the tenancy)

• Question 85:

  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.
  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.

  https://docs.cloud.oracle.com/iaas/Content/Compute/References/bestpracticescompute.htm 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 86:

  Which statement is true about Oracle Cloud Infrastructure (OCI) object storage support for server- side encryption?

  A. You must manually enable server-side encryption for each object as you upload to OCI object storage
  B. Objects are automatically encrypted as they are uploaded to object storage and decrypted upon retrieval
  C. You must manually decrypt the data when retrieving from OCI object storage
  D. Only the object data is encrypted and the user-defined metadata that is associated with the object is not encrypted
  B. Objects are automatically encrypted as they are uploaded to object storage and decrypted upon retrieval

  Encryption is automatically enabled for all data with no action required on the part of customers.

  -

  Oracle encrypt both the object data and the user-defined metadata associated with the object.

• Question 87:

  Your IT department wants to cut down storage costs, but also meet compliance requirements as set up by the central audit group. You have a legacy bucket with both Word does (*.docx) and Excel files (*.xlsx). Your auditors want to retain only Excel files for compliance purposes. Your IT departments wants to keep all other files for 365 days only. What two steps can you take to meet this requirement?

  A. Create Object Storage Lifecycle rules to archive objects from the legacy bucket after 365 days without any pattern matching
  B. Create Object Storage Lifecycle rules to delete objects from the legacy bucket after 365 days with a filter type - include by pattern: ''.docx
  C. It is not possible to meet this requirement
  D. Create Object Storage Lifecycle rules to delete objects from the legacy bucket after 365 days with a filter type - exclude by pattern: ''.xlsx"
  E. Create Object Storage Lifecycle rules to delete objects from the legacy bucket after 365 days without any pattern matching
  B. Create Object Storage Lifecycle rules to delete objects from the legacy bucket after 365 days with a filter type - include by pattern: ''.docx
  D. Create Object Storage Lifecycle rules to delete objects from the legacy bucket after 365 days with a filter type - exclude by pattern: ''.xlsx"

  ---

  Object Lifecycle Management lets you automatically manage the archiving and deletion of objects. By using Object Lifecycle Management to manage your Object Storage and Archive Storage data, you can reduce your storage costs and the amount of time you spend managing data. Use object name filters to specify which objects the lifecycle rule applies to. You can add object filters in any order. Object Lifecycle Management evaluates the precedence of the rules as follows: Pattern exclusions Pattern inclusions Prefix inclusions

• Question 88:

• Question 90:

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

  A. Check security lists and route tables of your virtual cloud network (VCN) and fix any issues associated with the rules
  B. Create separate listeners for each backend web server
  C. Delete and re-create your OCI load balancer
  D. Disable session persistence on your backend set
  D. Disable session persistence on your backend set
