  B. Deploy all web servers into multiple Availability Domains and behind a public load balancer, and deploy two single-node OCI database systems across two Availability Domains with Data Guard enabled.
  C. Deploy all web servers into multiple Availability Domains and behind a private load balancer, and deploy two single-node OCI database systems across two Availability Domains with Data Guard enabled.
  D. Deploy all web servers into one Availability Domain, and deploy a single-node OCI database system into a different Availability Domain.
  B. Deploy all web servers into multiple Availability Domains and behind a public load balancer, and deploy two single-node OCI database systems across two Availability Domains with Data Guard enabled.

• Question 92:

  A customer has launched a compute Instance in the Virtual Cloud Network (VCN), which has an Internet gateway, a service gateway, a default security lists and a default route table. Customer has opened up Port 22 in the security lists

  attached to the compute instance subnet, however is still unable to connect to compute instances using ssh.

  Which option would remedy this situation?

  A. Modify the route table associated with the VCN subnet in which the instance resides. Add a following route to the route table. Destination CIDR: 0.0.0.0/0 Target: Internet Gateway (IGW)
  B. Modify the security list associated with the VCN subnet in which the instance resides. Add a stateful egress rule to allow icmp traffic in addition to the port 22.
  C. Modify the route table associated with the VCN subnet in which the instance resides. Add a following route to the route table. Destination CIDR: 0.0.0.0/0 Target: Dynamic Routing Gateway (DRG)
  D. Modify the route table associated with the VCN subnet in which the instance resides. Add a following route to the route table. Destination CIDR: 0.0.0.0/0 Target: Service Gateway (SGW)
  A. Modify the route table associated with the VCN subnet in which the instance resides. Add a following route to the route table. Destination CIDR: 0.0.0.0/0 Target: Internet Gateway (IGW)

  ---

  You create an internet gateway in the context of a specific VCN. In other words, the internet gateway is automatically attached to a VCN. However, you can disable and re-enable the internet gateway at any time.

  For traffic to flow between a subnet and an internet gateway, you must create a route rule accordingly in the subnet's route table (for example, destination CIDR = 0.0.0.0/0 and target = internet gateway). If the internet gateway is disabled, that

  means no traffic will flow to or from the internet even if there's a route rule that enables that traffic. For the purposes of access control, you must specify the compartment where you want the internet gateway to reside. If you're not sure which

  compartment to use, put the internet gateway in the same compartment as the cloud network.

• Question 93:

  What happens when you run terraform plan?

  A. It configures, reconfigures, and instantiates resources and their dependencies.
  B. It shows the operator the course of action that would be taken if a change is applied.
  C. It deletes all existing resources and re-creates them.
  D. It shows a dependency graph.
  B. It shows the operator the course of action that would be taken if a change is applied.

  ---

  References:

  The terraform plan command is used to create an execution plan. Terraform performs a refresh, unless explicitly disabled, and then determines what actions are necessary to achieve the desired state specified in the configuration files.

  This command is a convenient way to check whether the execution plan for a set of changes matches your expectations without making any changes to real resources or to the state. For example, terraform plan might be run before

  committing a change to version control, to create confidence that it will behave as expected.

• Question 94:

  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 95:

  Which two tagging related items are valid attributes that may be included in payload of an audit log event? (Choose two.)

  A. Predefined values
  B. Free-form tags
  C. Tag variables
  D. Defined tags
  E. Cost-tracking tags
  F. Default tags
  B. Free-form tags
  D. Defined tags

• Question 97:

  You are about to upload log file (5 TiB size) to Oracle Cloud Infrastructure object storage and have decided to use multipart upload capability for a more efficient and resilient upload. Which two statements are true about multipart upload? (Choose two.)

  A. Individual object parts can be as small as 10 MiB or as large as 50 GiB
  B. While a multipart upload is still active, you cannot add parts even if the total number of parts is less than 10,000
  C. The maximum size for an uploaded object is 10 TiB
  D. You do not have to commit the upload after you have uploaded all the object parts
  A. Individual object parts can be as small as 10 MiB or as large as 50 GiB
  C. The maximum size for an uploaded object is 10 TiB

  ---

  With multipart upload, you split the object you want to upload into individual parts. Individual parts can be as large as 50 GiB or as small as 10 MiB. (Object Storage waives the minimum part size restriction for the last uploaded part.) Decide what part number you want to use for each part. Part numbers can range from 1 to 10,000. You do not need to assign contiguous numbers, but Object Storage constructs the object by ordering part numbers in ascending order. The maximum size for an uploaded object is 10 TiB While a multipart upload is still active, you can keep adding parts as long as the total number is less than 10,000. https://docs.cloud.oracle.com/en-us/iaas/Content/Object/Tasks/usingmultipartuploads.htm

• Question 98:

  You are responsible for creating and maintaining an enterprise application that consists of multiple storage volumes across multiple compute instances in Oracle Cloud Infrastructure (OCI). The storage volumes include boot volumes and block

  volumes for your data storage. You need to create

  backups of these storage volumes in the most time-efficient manner.

  How can you meet this requirement?

  A. Create clones of all boot volumes and block volumes one at a time.
  B. Create on-demand full backups of boot volumes, and copy data in block volumes to Object Storage using OCI CLI.
  C. Create on-demand full backups of block volumes, and create custom images from the boot volumes.
  D. Group together multiple storage volumes in a volume group and create volume group backups.
  D. Group together multiple storage volumes in a volume group and create volume group backups.
