Oracle Oracle Certifications 1Z0-1072-21 Questions & Answers

• Question 121:

  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

  Correct Answer: A

  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 122:

  You are in the process of setting up a highly available student registration website on Oracle Cloud Infrastructure (OCI). You use a load balancer and a database service on OCI. You launch two compute instances each in a different subnet and add them to the back end set of a public load balancer. The load balancer is configured correctly and working. You then deploy the student registration application on these two compute instances. The application can communicate with the database service. However, when you type the URL of this student registration application in your browser, no web page appears. What could be the cause?

  A. The security lists of the subnets on which the two instances are located do not have "allow" rules for port 80 and 443.

  B. The load balancer performed a health check on the application and found that compute instances were not in a healthy state and terminated the instances.

  C. The client requested https access to the application and the load balancer service does not support end-to-end SSL from the client to the listener to the back-end set.

  D. The Dynamic Routing Gateway is preventing the client traffic from your data center network from reaching the public IP of the load balancer.

  Correct Answer: A

• Question 123:

  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.

  Correct Answer: AB

  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.

• Question 124:

  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

  Correct Answer: BCE

  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 Robin Least Connections IP Hash

• Question 125:

  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

  Correct Answer: D

• Question 126:

  What does Terraform use to create, manage, and manipulate infrastructure resources?

  A. resources

  B. provisioner

  C. instances

  D. provider

  Correct Answer: D

  The Oracle Cloud Infrastructure provider is used to interact with the many resources supported by the Oracle Cloud Infrastructure. The provider needs to be configured with credentials for the Oracle Cloud Infrastructure account.

• Question 127:

  Which tool can automatically install Oracle Cloud Infrastructure CLI?

  A. Python

  B. RPM

  C. APT

  D. PIP

  Correct Answer: D

  References: https://docs.cloud.oracle.com/iaas/Content/API/SDKDocs/climanualinst.htm

• Question 128:

  Which two statements are true about the Oracle Cloud Infrastructure Object Storage Service? (Choose two.)

  A. It provides higher IOPS than Block Storage.

  B. It can be directly attached or detached from a compute instance.

  C. Data is stored redundantly only in a single AD.

  D. Data is stored redundantly across multiple availability domains (ADs) in a multi-AD region.

  E. It provides strong consistency.

  Correct Answer: DE

  STRONG CONSISTENCY When a read request is made, Object Storage always serves the most recent copy of the data that was written to the system. DURABILITY Object Storage is a regional service. Data is stored redundantly across multiple storage servers. Object Storage actively monitors data integrity using checksums and automatically detects and repairs corrupt data. Object Storage actively monitors and ensures data redundancy. If a redundancy loss is detected, Object Storage automatically creates more data copies. For more details about Object Storage durability, see the Oracle Cloud Infrastructure Object Storage FAQ. CUSTOM METADATA You can define your own extensive metadata as key-value pairs for any purpose. For example, you can create descriptive tags for objects, retrieve those tags, and sort through the data. You can assign custom metadata to objects and buckets using the Oracle Cloud Infrastructure CLI or SDK. See Software Development Kits and Command Line Interface for details. ENCRYPTION Object Storage employs 256-bit Advanced Encryption Standard (AES-256) to encrypt object data on the server. Each object is encrypted with its own key. Data encryption keys are encrypted with a master encryption key that is frequently rotated. Encryption is enabled by default and cannot be turned off.

• Question 129:

  Which three actions are required to configure a highly available and secure hybrid network between Oracle Cloud and your data center? (Choose three.)

  A. Define a non-overlapping IP Address Space between the data center and the cloud.

  B. Configure each of the CPEs to leverage each of the IPSec Tunnels created by the connection process.

  C. Create two or more CPEs that map to the private IP addresses of the customer routers used in the IPSec VPN Tunnel.

  D. Define a default route table entry for the VCN that directs all traffic to the data center network to a single DRG.

  E. Create dynamic routing gateways in more than one AD within your region.

  Correct Answer: ABC

• Question 130:

  You have one database-style application that frequently makes many random reads and writes across the

  dataset.

  A. Object Storage Service

  B. Archive Storage Service

  C. File Storage Service

  D. Block Storage Service

  Correct Answer: D
