Oracle 1z0-1072-22 Sample Questions – Free Practice Test & Real Exam Prep

Question #1

You have an Oracle Cloud Infrastructure (OCI) load balancerdistributing traffic via an evenly-weighted round robin policy to your back-end web servers. You notice that one ofyour web servers is receiving more traffic than other web servers. How can you resolve this to make sure traffic is evenly distributed across all back-end webservers?

  • A. Disable cookie-based session persistence on your backend set. 
  • B. Change keep-alive setting between the load balancer and backend server. 
  • C. Disable SSL configuration associated with your backend set. 
  • D. Create separatelisteners for each backend web server. 
Question #2

You are managing a tier-1 OLTP application on an Autonomous Transaction Processing (ATP) database. Your business needs to run hourly batch processes on this ATP database that may consume more CPUs than what isavailable on the server. How can you limit these batch processes to not interfere with the OLTP transactions?

  • A. Configure ATP resource management rules to change CPU/IO shares for the consumer group of batch processes. 
  • B. Copy OLTP data into new tablesin a new table space and run batch processes against these new tables. 
  • C. Disable automated backup during the batch process operations. 
  • D. ATP is designed for OLTP workload only, you cannot run batch processes on ATP. 
Answer: A
Explanation: 
Autonomous TransactionProcessing comes with predefined CPU/IO shares assigned to different consumer groups. You can modify these predefined CPU/IO shares if your workload requires different CPU/IO resource allocations. By default, the CPU/IO shares assigned to the consumer groups TPURGENT, TP, HIGH, MEDIUM, and LOW are 12, 8, 4, 2, and 1, respectively. The shares determine how much CPU/IO resources a consumer group can use with respect to the other consumer groups. With the default settings the consumer group TPURGENT will be able to use 12 times more CPU/IO resources compared to LOW, when needed. The consumer group TP will be able to use 4 times more CPU/IO resources compared to MEDIUM, when needed.

Question #3

Your company has been running several small applications in Oracle Cloud Infrastructure and is planning a proof-of-concept (POC) to deploy PeopleSoft. If your existing resources are being maintained in the root compartment, what is therecommended approach for defining security for the upcoming POC?

  • A. Create a new compartment for the POC and grant appropriate permissions to create and manage resources within the compartment. 
  • B. Provision all new resources into the root compartment. Grant permissions that only allow for creation and management of resources specific to the POC. 
  • C. Provision all new resources into the root compartment. Use defined tags to separate resources that belong to different applications. 
  • D. Create a new tenancy for the POC. Provision all new resources into the root compartment. Grant appropriate permissions to create and manage resources within the root compartment. 
Answer: A

Question #4

Which two statements below are correct with respect to adding secondary Virtual Network Interface Cards (VNICs) to an existing compute instance in Oracle Cloud Infrastructure? (Choose two.)

  • A. The secondaryVNIC is required to be in the same Virtual Cloud Network (VCN), but can be in different subnet, as the primary VNIC. 
  • B. The primary and secondary VNIC association can be in different virtual cloud networks (VCNs). 
  • C. You cannot assign an Ephemeral Public IP to a secondary VNIC. 
  • D. The primary and secondary VNIC association must be in the same availability domain. 
  • E. You can remove the primary VNIC after the secondary VNIC's attachment is complete. 
Answer: B,D
Explanation: “You can add secondary VNICs to an instanceafter it’s launched. Each secondary VNIC can be in a subnet in the same VCN as the primary VNIC, or in a different subnet that is either in the same VCN or a different one. However, all the VNICs must be in the same availability domain as the instance.”

Question #5

You deployed an Oracle Cloud Infrastructure (OCI) compute instance (VM.Standard2.16) to run a SQL database. After a few weeks, you need to increase disk performance by usingNVMe disks but keeping the same number of CPUs. As a first step, you terminate the instance and preserve the boot volume. What is the next step?

  • A. Create a new instance using a VM.DenseIO2.16 shape using the preserved boot volume and move the SQL Database data to block volume 
  • B. Create a new instance using a VM.DenseIO2.8 shape using the preserved boot volume and move the SQL Database data to NVMe disks 
  • C. Create a new instance using a VM.Standard1.16 shape using the preserved boot volume and move the SQL Database data to NVMe disks 
  • D. Create a new instance using a VM.DenseIO2.16 shape using the preserved boot volume move the SQL Database data to NVMe disks 
Answer: D
Explanation:
Question #6

Which two methods are supportedfor migrating your on-premises Oracle database to an Oracle Autonomous Transaction Processing (ATP) database in Oracle Cloud Infrastructure? (Choose two.)

  • A. Load text files into ATP using SQL Developer. 
  • B. Use RMAN duplicate. 
  • C. Use Oracle Data Pump. 
  • D. Transfer the physical database files and re-create the database. 
  • E. Use database backup and restore. 
Question #7

Which two statements are true about Oracle Cloud Infrastructure storage services?

  • A. You can move Object Storage buckets, Block Volumes and File Storage mount targets between compartments. 
  • B. File storage mount target does not provide a private IP address, while the Object Storage bucket provides one. 
  • C. File Storage uses the network file system (NFS) protocol, whereas Block Volume uses ISCSI. 
  • D. Block Volume service scales to Exabytes per Instance, while File Storage service offers unlimited scalability. 
  • E. You can take Incremental snapshots of BlockVolumes, File Storage file systems and Object Storage buckets. 
Answer: A,C

Question #8

You created a public subnet and an internet gateway in your virtual cloud network (VCN) of Oracle Cloud Infrastructure. The public subnet has an associated route table and securitylist. However, after creating several compute instances in the public subnet, none can reach the Internet. Which two are possible reasons for the connectivity issue? (Choose two.)

  • A. The route table has no default route forrouting traffic to the internet gateway. 
  • B. There is no stateful egress rule in the security list associated with the public subnet. 
  • C. There is no dynamic routing gateway (DRG) associated with the VCN. 
  • D. There is no stateful ingress rule in the securitylist associated with the public subnet. 
  • E. A NAT gateway is needed to enable the communication flow to internet. 
Answer: A,B
Explanation: An internet gateway as an optional virtual router that connects the edge of the VCN with the internet. To use the gateway, the hosts on both ends of the connection must have public IP addresses for routing. Connections that originate in your VCN and are destined for a public IP address (either inside or outside the VCN) go through the internet gateway. Connections that originate outside the VCN and are destined for a public IP address inside the VCN go through the internet gateway. Working with Internet Gateways 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 reenable the internet gateway at any time. Compare this with a dynamic routing gateway (DRG), which you create asa standalone object that you then attach to a particular VCN. DRGs use a different model because they're intended to be modular building blocks for privately connecting VCNs to your on-premises network. For traffic to flow between a subnet and an internetgateway, 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 more information, see Route Tables. For the purposes of access control, you must specify thecompartment 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. For more information, see Access Control. You may optionally assign a friendly name to the internet gateway. It doesn't have to be unique, and you can change it later. Oracle automatically assigns the internet gateway a unique identifier called an Oracle Cloud ID (OCID). For more information, see Resource Identifiers. To delete an internet gateway, it does not have to be disabled, but theremust not be a route table that lists it as a target. AS per compute instances can connect to the Internet so you use egress no ingress

Question #9

  • B. Primary is a 2-node RAC DB system and Standby is a 2-node RAC DB system. 
  • C. Primary is a 1-node RAC DB system and Standby is a 1-node RAC DB system. 
  • D. Primary is a 2-node RAC DB system and Standby is a 1-node RAC DB system. 
  • E. Primary is a Bare Metal DB system and Standby is a 1-node RAC DB system. 
Question #10
