Which OCr feature would you leverage to meet this requirement?

  A. Use VCN security rules to control access for the NFS clients
  B. Use OCI Identity Access Management to control access for the NFS clients
  C. Use File Storage NFS Export Options to control access for the NFS clients
  D. Use NFS security to control access for the NES clients
  C. Use File Storage NFS Export Options to control access for the NFS clients

  Oracle Cloud Infrastructure File Storage service provides a durable, scalable, secure, enterprise-grade network file system. You can connect to a File Storage service file system from any bare metal, virtual machine, or container instance in your Virtual Cloud Network (VCN). You can also access a file system from outside the VCN using Oracle Cloud Infrastructure FastConnect and Internet Protocol security (IPSec) virtual private network (VPN). EXPORT Exports control how NFS clients access file systems when they connect to a mount target. File systems are exported (made available) through mount targets. Each mount target maintains an export set which contains one or many exports. A file system must have at least one export in one mount target in order for instances to mount the file system. The information used by an export includes the file system OCID, mount target OCID, export set OCID, export path, and client export options. For more information, see Managing Mount Targets. EXPORT SET Collection of one or more exports that control what file systems the mount target exports using NFSv3 protocol and how those file systems are found using the NFS mount protocol. Each mount target has an export set. Each file system associated with the mount target has at least one export in the export set. EXPORT PATH A path that is specified when an export is created. It uniquely identifies the file system within the mount target, letting you associate up to 100 file systems to a single mount target. This path is unrelated to any path within the file system itself, or the client mount point path. EXPORT OPTIONS NFS export options are a set of parameters within the export that specify the level of access granted to NFS clients when they connect to a mount target. An NFS export options entry within an export defines access for a single IP address or CIDR block range. For more information, see Working with NFS Export Options.

  D. You can manage Oracle database initialization parameters at a global level.
  B. You cannot manage the database as sys/sysdba.
  C. You have full control over the automatic backup schedule and retention periods.

• Question 173:

  You have provisioned an Autonomous Data Warehouse (ADW) database with 16 enabled OCPUs and need to configure the consumer group for your application. Which two are true when deciding the number of sessions for each application? (Choose two.)

  A. The MEDIUM and LOW consumer group can run up to 16 concurrent SQL statements if HIGH consumer group has 0 SQL statements
  B. The HIGH consumer group can run up to 16 concurrent SQL statements as long as MEDIUM and LOW consumer groups have 0 SQL statements
  C. The MEDIUM consumer group can run 20 concurrent SQL statements when HIGH consumer group has 0 SQL statements
  D. The HIGH consumer group can run up to 16 concurrent SQL statements in addition to 32 concurrent SQL statements in MEDIUM and LOW consumer group each
  E. The HIGH consumer group can run 3 concurrent SQL statements when MEDIUM consumer group has 0 SQL statements
  C. The MEDIUM consumer group can run 20 concurrent SQL statements when HIGH consumer group has 0 SQL statements
  E. The HIGH consumer group can run 3 concurrent SQL statements when MEDIUM consumer group has 0 SQL statements

• Question 174:

  Which two Oracle Cloud Infrastructure services use a Dynamic Routing Gateway?

  A. OCI FastConnect Public Peering
  B. Local Peering
  C. OCI FastConnect Private Peering
  D. Internet Gateway
  E. OCI IPSec VPN Connect
  C. OCI FastConnect Private Peering
  E. OCI IPSec VPN Connect

  ---

  You can think of a DRG as a virtual router that provides a path for private traffic (that is, traffic that uses private IPv4 addresses) between your VCN and networks outside the VCN's region. You use a DRG when connecting your existing on-

  premises network to your virtual cloud network (VCN) with one (or both) of these:

  IPSec VPN

  Oracle Cloud Infrastructure FastConnect (Private Only) You also use a DRG when peering a VCN with a VCN in a different region:

  Remote VCN Peering (Across Regions)

  

• Question 175:

  You are running your warehouse using Autonomous Data Warehouse (ADW) service and you noticed that a newly configured batch job is always running in serial even through nothing else is running in the database. All your jobs are configured to run with parallelism enabled. What could be the reason for this batch job to run in serial?

  A. The batch job depends on only one table and parallelism cannot be enabled on single-table queries.
  B. The parallelism of batch job depends on the number of ADW databases involved in the query.
  C. The new batch job is connected to LOW consumer group.
  D. The new batch job runs on database tables that are not enable for parallel execution.
  E. Parallelism on the database is controlled by the application, not the database.
  C. The new batch job is connected to LOW consumer group.

• Question 176:

  You create a public Load Balancer instance and configure a back end set "BES1" with one back end server running a service on port 80. You also create a listener on port 80 and configure that listener to use the back end set "BES1". A client

  makes one HTTP request to the Load Balancer with the correct protocol and port.

  How many connections does the Load Balancer maintain?

  A. 1
  B. 2
  C. 4
  D. 3
  B. 2

• Question 177:

  Your company is developing a new database application in Oracle Cloud Infrastructure. You need to test application functionality including a hardware failure scenario. Since the application is still in the development phase, you want to minimize infrastructure costs. Which database service deployment option meets this requirement?

  A. two node real application cluster (RAC) system
  B. Autonomous Data Warehouse (ADW) system as it provides auto fail over functionality
  C. two node bare metal system with data guard enabled
  D. single node bare metal system
  A. two node real application cluster (RAC) system

• Question 178:

  Your company has decided to move a few applications to Oracle Cloud Infrastructure and you have been asked to design it for Disaster Recovery (DR). One of the items of your design is to deploy the DR at least 300 miles from the home site and minimize the network latency as much as possible. Based on that, what will be the recommended deployment?

  A. Deploy applications in two separated VCNs in different Availability Domains and use VCN Remote Peering
  B. Deploy applications in different regions and have them connected using VCN Remote Peering
  C. Deploy applications in two separated VCNs in different regions and use VCN Local Peering
  D. Deploy applications on the same region splitting workloads across Availability Domains.
  B. Deploy applications in different regions and have them connected using VCN Remote Peering

• Question 179:

  Which statement is true about the Oracle Cloud Infrastructure File Storage Service Mount Target?

  A. You can access multiple file systems through a single mount target
  B. Mount target has a public IP address and DNS name
  C. Mount target lives in a single subnet of your choice, but is not highly available
  D. Each mount target requires six internal IP addresses in the subnet to function
  A. You can access multiple file systems through a single mount target

  ---

  A mount target is an NFS endpoint that lives in a VCN subnet of your choice and provides network access for file systems. The mount target provides the IP address or DNS name that is used together with a unique export path to mount the file system. A single mount target can export many file systems. Typically, you create your first mount target and export when you create your first file system. The mount target maintains an export set which contains all of the exports for its associated file systems. Limitations and Considerations

  Each availability domain is limited to two mount targets by default. However, you can export up to 100 file systems through each mount target.

  See Service Limits for a list of applicable limits and instructions for requesting a limit increase. Each mount target requires three internal IP addresses in the subnet to function. Two of the IP addresses are used during mount target creation.

  The third IP address must remain available for the mount target to use for high availability failover.

  The File Storage service doesn't "reserve" the third IP address required for high availability failover. Use care when designing your subnets and file systems to ensure that sufficient IP addresses remain available for your mount targets.
