Oracle 1Z0-1072-22 Online Questions & Answers

• Question 31:

  You are a network architect and have designed the network infrastructure of a three-tier application on Oracle Cloud Infrastructure (OCI). In the architecture, back-end DB servers are in a private subnet. One of your DB administrators

  requests to have access to OCI object storage service.

  How can you meet this requirement?

  A. Add a new route rule to the private subnet route table to route default traffic to the internet gateway.
  B. Attach a public IP address to the instances in the private subnet, and then add a new route rule to the private subnet route table to route default traffic to the internet gateway.
  C. Create a dynamic routing gateway (DRG) and attach it to your virtual cloud network (VCN). Add a default route rule to the private subnets route table and set the target as DRG.
  D. Create a service gateway, add a new route rule to the private subnet route table that uses object storage as target type.
  D. Create a service gateway, add a new route rule to the private subnet route table that uses object storage as target type.

  A service gateway lets resources in your VCN privately access specific Oracle services, without exposing the data to an internet gateway or NAT. The resources in the VCN can be in a private subnet and use only private IP addresses. The

  traffic from the VCN to the service of interest travels over the Oracle network fabric and never traverses the internet. To give your VCN access to a given service CIDR label, you must enable that service CIDR label for the VCN's service

  gateway. You can do that when you create the service gateway, or later after it's created. You can also disable a service CIDR label for the service gateway at any time. For traffic to be routed from a subnet in your VCN to a service gateway,

  you must add a rule accordingly to the subnet's route table. The rule must use the service gateway as the target.

  A. Primary and standby databases must be in the same OCI region.
  B. Both database systems must be in the same compartment.
  C. Database systems need not be the same shape type (e.g, primary database can be a virtual machine, and standby database a bare metal shape, and vice versa).

• Question 35:

  Which two statements are true regarding cloning a block volume?

  A. You can change the block volume performance when creating a clone
  B. You can clone block volumes across regions
  C. You can change the block volume size when creating a clone
  D. You can skip block volume encryption when creating a clone
  A. You can change the block volume performance when creating a clone
  C. You can change the block volume size when creating a clone

  ---

  You can create a clone from a volume using the Block Volume service. Cloning enables you to make a copy of an existing block volume without needing to go through the backup and restore process. A cloned volume is a point-in-time direct

  disk-to-disk deep copy of the source volume, so all the data that is in the source volume when the clone is created is copied to the clone volume. You can only create a clone for a volume within the same region, availability domain and tenant.

  You can create a clone for a volume between compartments as long as you have the required access permissions for the operation.

  during create a clone you can do the following

  If you want to clone the block volume to a larger size volume, check Custom Block Volume Size (GB) and then specify the new size. You can only increase the size of the volume, you cannot decrease the size. If you clone the block volume to

  a larger size volume, you need to extend the volume's partition. See Extending the Partition for a Block Volume for more information. If you want to change the elastic performance setting when cloning the volume, check Custom Block Volume

  Performance and select the elastic performance setting you want the volume clone to use. See Block Volume Elastic Performance for more information. You can also change the elastic performance setting after you have cloned the volume,

  see Block Volume Elastic Performance. If you leave Custom Block Volume Performance unchecked, the cloned volume will use the same elastic performance setting as the source volume.

• Question 36:

  Which deployment architecture is offered when you deploy the Platform Service Manager based Database Cloud Service (DBCS) onto Oracle Cloud Infrastructure?

  A. Two node Primary RAC database leveraging ACFS for the shared file system
  B. Single Instance database with a Single Instance Data Guard in Maximum Performance mode
  C. Single Instance database with a Single Instance Data Guard in Maximum Protection mode
  D. Two node Primary RAC database with a two node RAC Data Guard Standby in Maximum Performance mode
  D. Two node Primary RAC database with a two node RAC Data Guard Standby in Maximum Performance mode

• Question 37:

  Which two parameters are required in a back end set's HTTP health check? (Choose two.)

  A. response body
  B. URL path
  C. timeout
  D. port
  E. status code
  B. URL path
  D. port

  ---

  https://docs.cloud.oracle.com/iaas/Content/GSG/Tasks/loadbalancing.htm#Create Enter the Health Check details.

  Load Balancing automatically checks the health of the instances for your load balancer. If it detects an unhealthy instance, it stops sending traffic to the instance and reroutes traffic to healthy instances. In this step, you provide the information

  required to check the health of servers in the backend set and ensure that they can receive data traffic.

  Protocol: Select HTTP.

  Port: Enter 80

  URL Path (URI): Enter /

  The rest of the fields are optional and can be left blank for this tutorial.

• Question 38:

  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
