Oracle 1Z0-1072-20 Online Questions & Answers

• Question 91:

  Your organization has deployed a large, complex application across multiple compute instances in Oracle Cloud Infrastructure (OCI). These compute instances also have block volume storage attached to them. You want to create a time

  consistent backup of these block volume storage.

  Which implementation strategy should be used?

  A. Create a manual backup of each volume
  B. Use scripts available in OCI to backup block volume storage
  C. Group volumes in a volume group first and then use available scripts in OCI
  D. Group volumes in a volume group and create a manual backup of the volume group
  D. Group volumes in a volume group and create a manual backup of the volume group

  ---

  The Oracle Cloud Infrastructure Block Volume service provides you with the capability to group together multiple volumes in a volume group. A volume group can include both types of volumes, boot volumes, which are the system disks for

  your Compute instances, and block volumes for your data storage. You can use volume groups to create volume group backups and clones that are point- in-time and crash-consistent.

  This simplifies the process to create time-consistent backups of running enterprise applications that span multiple storage volumes across multiple instances. You can then restore an entire group of volumes from a volume group backup.

  To create a backup of the volume group

  Open the navigation menu. Under Core Infrastructure, go to Block Storage and click Volumes Groups. In the Volume Groups list, click Create Volume Group Backup in the Actions menu for the volume group you want to create a backup for.

• Question 92:

  Which two are required to create an IPSec VPN connection? (Choose two.)

  A. security list
  B. static route CIDR
  C. name
  D. compute instance
  A. security list
  B. static route CIDR

• 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:

  What is the default backup location for database backup on Database Cloud Service (DBCS)?

  A. Object Storage on Oracle Cloud Infrastructure
  B. ASM diskgroup
  C. block volume
  D. locally attached NVMe on Virtual Machine
  A. Object Storage on Oracle Cloud Infrastructure

• Question 95:

  A customer has established an Oracle Cloud Infrastructure (OCI) FastConnect connection to OCI. The virtual circuit is up and routes are being advertised from the customer's end, however the customer is unable to ping from compute

  instances inside the virtual cloud network (VCN) to servers residing in its on-premises data center.

  Which two options on OCI would remedy this situation? (Choose two.)

  A. Modify the route table associated with the VCN subnet in which the instance resides. Add a route to the customer's on-premises network via the Dynamic Routing Gateway (DRG).
  B. Modify the security list associated with the VCN subnet in which the instance resides. Add a stateful egress rule to allow ICMP traffic to the customer's on-premises network.
  C. Modify the security list associated with the VCN subnet in which the instance resides. Add a stateful ingress rule to allow ICMP traffic from anywhere.
  D. Modify the default VCN route table to add a route back to the customer's on-premises network via the DRG.
  A. Modify the route table associated with the VCN subnet in which the instance resides. Add a route to the customer's on-premises network via the Dynamic Routing Gateway (DRG).
  B. Modify the security list associated with the VCN subnet in which the instance resides. Add a stateful egress rule to allow ICMP traffic to the customer's on-premises network.

• Question 96:

  Your company uses the Oracle Cloud Infrastructure (OCI) Object Storage service to share large data sets with its data science team. The data science team consists of 20 people who work from offices in Washington, D.C., and Tokyo. While working in these offices, employees are assigned an IP address from the public IP range 129.146.31.0/27 Which two steps should you take to ensure that the Object Storage bucket used in this scenario was only accessible from these office locations? (Choose two.)

  A. Write an IAM policy that includes the conditional statement where request.networkSource.name =CorpNet
  B. Set the bucket visibility to public and only share the URL with the data science team via email
  C. Create a pre-authenticated request for each data set and only share with the data science team via email
  D. Create a Network Source named CorpNetwork with a CIDR block of 129.146.31.0/27
  E. Create a Network Source named CorpNetwork with a CIDR block of 129.146.0.0/16
  F. Write an IAM policy that includes the conditional statement where request.region = 129.146.31.0/27
  C. Create a pre-authenticated request for each data set and only share with the data science team via email
  E. Create a Network Source named CorpNetwork with a CIDR block of 129.146.0.0/16

• Question 97:

  Which two statements are true about restoring a volume from a block volume backup in Oracle Cloud Infrastructure Block Volume service?

  A. You can restore a volume from any full volume backup but not from an Incremental backup.
  B. You can only restore a volume to the same availability domain in which the original block volume resides.
  C. You can restore a block volume backup to a larger volume size.
  D. You can restore a volume to any availability domain within the same region where the backup is stored.
  E. You can restore only one volume from a manual block volume backup.
  C. You can restore a block volume backup to a larger volume size.
  D. You can restore a volume to any availability domain within the same region where the backup is stored.

• Question 98:

  Why are two subnets required to create a public load balancer when additional subnets are often used for back-end servers? (Choose two.)

  A. Routing is simpler when the load balancer is not in the same subnet as the back-end server.
  B. Performance is higher when more subnets are used.
  C. Additional subnets for back-end servers allow for separate route tables for these servers.
  D. Additional subnets for back-end servers allow for separate security lists for these servers.
  B. Performance is higher when more subnets are used.
  D. Additional subnets for back-end servers allow for separate security lists for these servers.

• Question 99:

  Which two choices are true for Autonomous Data Warehouse (ADW)? (Choose two.)

  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.
