Oracle 1Z0-1072 Online Questions & Answers

• Question 121:

  You have an instance running in a development compartment that needs to make API calls against other OCI services, but you do not want to configure user credentials or a store a configuration file on the instance. How can you meet this requirement?

  A. Create a dynamic group with matching rules to include your instance
  B. B. Instances can automatically make calls to other OCI services
  C. C. Instances are secure and cannot make calls to other OCI services
  D. D. Create a dynamic group with matching rules to include your instance and write a policy for this dynamic group
  D. D. Create a dynamic group with matching rules to include your instance and write a policy for this dynamic group

  ---

  Dynamic groups allow you to group Oracle Cloud Infrastructure computer instances as "principal" actors (similar to user groups).

  When you create a dynamic group, rather than adding members explicitly to the group, you instead define a set of matching rules to define the group members. For example, a rule could specify that all instances in a particular compartment are members of the dynamic group. The members can change dynamically as instances are launched and terminated in that compartment.

  A dynamic group has no permissions until you write at least one policy that gives that dynamic group permission to either the tenancy or a compartment. When writing the policy, you can specify the dynamic group by using either the unique name or the dynamic group's OCID. Per the preceding note, even if you specify the dynamic group name in the policy, IAM internally uses the OCID to determine the dynamic group.

• Question 122:

  Which two statements about file storage service (FSS) are accurate? (Choose two.)

  A. FSS leverages UNIX user group and permission checking for file access security
  B. Encryption of file system in FSS is optional
  C. Identity and Access Management (IAM) controls which file systems are mountable by which instances
  D. Security lists can be used as a virtual firewall to prevent an instance from mounting an FSS mount target within the same subnet
  E. Data in transit to an FSS mount target is encrypted
  A. FSS leverages UNIX user group and permission checking for file access security
  E. Data in transit to an FSS mount target is encrypted

  ---

  All data is encrypted at rest. and In-transit encryption provides a way to secure your data between instances and mounted file systems using TLS v. 1.2 (Transport Layer Security) encryption. File Storage service supports the AUTH_UNIX style of authentication and permission checking for remote NFS client requests.

• Question 123:

  Which two are true for Oracle Cloud Infrastructure DNS? (Choose two.)

  A. It can function only as a primary DNS.
  B. It supports other cloud providers such as AWS and Azure.
  C. It supports segregation of traffic by using the private pool.
  D. It does not provide DDoS protection.
  B. It supports other cloud providers such as AWS and Azure.
  C. It supports segregation of traffic by using the private pool.

  References:

  B: Support for Oracle Cloud Infrastructure, other Cloud provider endpoints (AWS, Azure) and private assets, including Cloud, CDNs and Data Centers

  C: Customers may purchase Oracle Cloud Infrastructure Private Pool and Vanity Nameserver to have their Domain Names and Zones under a private IP pool with dedicated nameservers to segregate from those of other customers in order to reduce the risk of external issues affecting their websites.

• Question 124:

  In which language are Terraform and Terraform providers written?

  A. Python
  B. Go
  C. C
  D. Ruby
  B. Go

• Question 125:

  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 126:

  Which two statements are true about data guard service on DB Systems in Oracle Cloud Infrastructure (OCI)? (Choose two.)

  A. Data guard implementation requires two DB Systems, one running the primary database on a virtual machine and the standby database running on bare metal
  B. Data guard configuration on the OCI is limited to one standby database per primary database
  C. Data guard configuration on the OCI is limited to a virtual machine only
  D. Data guard implementation requires two DB Systems, one containing the primary database and one containing the standby database
  B. Data guard configuration on the OCI is limited to one standby database per primary database
  D. Data guard implementation requires two DB Systems, one containing the primary database and one containing the standby database

• Question 127:

  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.

  ---

  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 128:

  Which two are valid options when migrating a database from on-premise to Oracle Cloud Infrastructure? (Choose two.)

  A. snapping or cloning storage form on-premise to Oracle Cloud Infrastructure
  B. performing a backup to Oracle Cloud Infrastructure Object Storage, and then restoring to a database server on Oracle Cloud Infrastructure
  C. performing RMAN backup to an on-premise storage device, and then shipping to Oracle Cloud Infrastructure
  D. converting the Oracle database to a NoSQL database and migrating to Oracle Cloud Infrastructure by using rsync file copy
  A. snapping or cloning storage form on-premise to Oracle Cloud Infrastructure
  C. performing RMAN backup to an on-premise storage device, and then shipping to Oracle Cloud Infrastructure

• Question 129:

  Which three load-balancing policies can be used with a back end set? (Choose three.)

  A. Throughput
  B. IP Hash
  C. Weighted Round Robin
  D. CPU Utilization
  E. Least Connections
  B. IP Hash
  C. Weighted Round Robin
  E. Least Connections

  ---

  References:

  After you create a load balancer, you can apply policies to control traffic distribution to your backend servers. The Load Balancing service supports three primary policy types:

  Round RobinLeast ConnectionsIP Hash

• Question 130:

  Which two actions will occur when a back-end server that is registered with a backend set is marked to drain connections? (Choose two.)

  A. It disallows new connections to that backend server.
  B. It keeps the connections to that instance open and attempts to complete any in-flight requests.
  C. It redirects the requests to a user-defined error page.
  D. It immediately closes all existing connections to that instance.
  E. It forcibly closes all connections to that instance after a timeout period.
  A. It disallows new connections to that backend server.
  B. It keeps the connections to that instance open and attempts to complete any in-flight requests.

  ---

  References: 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.
