• Question 112:

  Your on-premises hosted application uses Oracle database server. Your database administrator must have access to the database server for managing the application. Your database server is sized for seasonal peak workloads, which

  results in high licensing costs. You want to move your application to Oracle Cloud Infrastructure (OCI) to take advantage of CPU scaling options.

  Which database offering on OCI would you select?

  A. bare metal DB systems
  B. VM DB systems
  C. Autonomous Transactions Processing (ATP)
  D. Autonomous Data Warehouse (ADW)
  A. bare metal DB systems

  -

  In, Oracle Autonomous Database, Customers are not given OS logons or SYSDBA privileges to prevent phishing attacking.

  -

  If a bare metal DB system requires more compute node processing power, you can scale up (increase) the number of enabled CPU cores in the system without impacting the availability of that system.

  You cannot change the number of CPU cores for a virtual machine DB system in the same way as metal DB system. Instead, you must change the shape to one with a different number of OCPUs Changing the shape does not impact the

  amount of storage available to the DB system. However, the new shape can have different memory and network bandwidth characteristics, and you might need to reapply any customizations to these aspects after the change.

• Question 113:

  In which language are Terraform and Terraform providers written?

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

• Question 114:

  You have deployed a compute instance (VM.Standard2.24) to run an Oracle database. With this set up, you run into some performance issues and want to leverage an OCI Dense IO shape (VM.DenseIO2.24), with which you get 25.6 TB local NVMe SSD. You do not want to lose the configuration changes you made to the instance. Which of the following TWO steps ARE NOT required to make this transition?

  A. Terminate the VM.Standard2.24 instance and do not preserve the boot volume
  B. Create a new instance using the VM.Dense102.24 shape using the preserved boot volume and move the Oracle Database data to NVMe disks
  C. Terminate the VM.Standard2.24 instance and preserve the boot volume
  D. Create a new instance using a VM.DenseIO2.24 shape using the preserved boot volume and move the Oracle Database data to block volumes
  A. Terminate the VM.Standard2.24 instance and do not preserve the boot volume
  D. Create a new instance using a VM.DenseIO2.24 shape using the preserved boot volume and move the Oracle Database data to block volumes

  ---

  You can permanently terminate (delete) instances that you no longer need. Any attached VNICs and volumes are automatically detached when the instance terminates. Eventually, the instance's public and private IP addresses are released and become available for other instances. By default, the instance's boot volume is deleted when you terminate the instance, however you can preserve the boot volume associated with the instance, so that you can attach it to a different instance as a data volume, or use it to launch a new instance. Dense I/O Shapes Designed for large databases, big data workloads, and applications that require high-performance local storage. DenseIO shapes include locally-attached NVMe-based SSDs. so once you create the VM.DenseIO you need to moce the Database to locally-attached NVMe-based SSDs

• Question 115:

  A customer has established an Oracle Cloud Infrastructure (OCI) FastConnect connection to OCI. The virtual circuit is up and routes are being advertised from the customer's end, however the customer is unable to ping from compute

  instances inside the virtual cloud network (VCN) to servers residing in its on-premises data center.

  Which two options on OCI would remedy this situation? (Choose two.)

  A. Modify the route table associated with the VCN subnet in which the instance resides. Add a route to the customer's on-premises network via the Dynamic Routing Gateway (DRG).
  B. Modify the security list associated with the VCN subnet in which the instance resides. Add a stateful egress rule to allow ICMP traffic to the customer's on-premises network.
  C. Modify the security list associated with the VCN subnet in which the instance resides. Add a stateful ingress rule to allow ICMP traffic from anywhere.
  D. Modify the default VCN route table to add a route back to the customer's on-premises network via the DRG.
  A. Modify the route table associated with the VCN subnet in which the instance resides. Add a route to the customer's on-premises network via the Dynamic Routing Gateway (DRG).
  B. Modify the security list associated with the VCN subnet in which the instance resides. Add a stateful egress rule to allow ICMP traffic to the customer's on-premises network.

• Question 116:

  You are tasked with creating a highly available clustered application on Oracle Cloud Infrastructure consisting of three nodes. The round-trip latency between nodes must be less than 500 祍 (micro- seconds) and your cluster should be

  resilient to hardware failure.

  What is the recommended deployment strategy?

  A. Deploy the cluster nodes in a single region and deploy each node into a different AD. Select the same fault domain in each AD to ensure consistency.
  B. Deploy the cluster nodes in two separate regions and take advantage of multiple availability domains (ADs) in each region.
  C. Deploy the cluster nodes in a single region and deploy each node into a different AD.
  D. Deploy the cluster nodes in a single region and deploy each node in different fault domains within a single AD.
  D. Deploy the cluster nodes in a single region and deploy each node in different fault domains within a single AD.

• Question 117:

  In what two ways does Oracle Cloud Infrastructure (OCI) file storage service differ from OCI object storage and block volume services?

  A. You can move object storage buckets, block volumes and file storage mount targets between compartments.
  B. File Storage uses the network file system (NFS) protocol, whereas block volume uses iSCSI.
  C. Block volume service Is NVMe based, while file storage service is not.
  D. File storage mount target does not provide a private IP address, while the object storage bucket provides one.
  A. You can move object storage buckets, block volumes and file storage mount targets between compartments.
  B. File Storage uses the network file system (NFS) protocol, whereas block volume uses iSCSI.

  ---

  The mount target provides the IP address or DNS name that is used together with a unique export path to mount the file system. You can move mount targets from one compartment to another.

• Question 118:

  Which two statements are true about Database Cloud Service (DBCS)? (Choose two.)

  A. Data Guard as a Service is offered among regions.
  B. You have full control over backup schedule and retention.
  C. You can manage Oracle parameters at a global system level.
  D. You cannot manage the database as sys/sysdba.
  B. You have full control over backup schedule and retention.
  C. You can manage Oracle parameters at a global system level.

  Can I set up Data Guard across Availability Domains?

  Yes, you can set up Data Guard in the same or different Availability Domains in a region. However, Oracle recommends that you set up your Data Guard configuration across Availability Domains. Can I set up Data Guard across Oracle Cloud

  Infrastructure regions? Yes, you can set up Data Guard across regions,

  "but the Database Cloud Service Data Guard feature currently does not support it. " You can manually set up Data Guard across regions by logging on to your host and using DGMGRL. You must enable an internet gateway on the primary and standby DB system VCN for Data Guard to transport logs across regions. Learn more about DGMGRL. To configure a Data Guard system across regions or between on-premises and Oracle Cloud Infrastructure DB systems, you must access the database host directly and use the DGMGRL utility. https://docs.cloud.oracle.com/iaas/Content/Database/Tasks/usingdataguard.htm

• Question 119:

  Which two statements about fault domains are true? (Choose two.)

  A. A fault domain is a grouping of hardware and infrastructure within an availability domain
  B. Each availability domain contains three fault domains
  C. A failed instance in a fault domain is automatically relaunched
  D. A fault domain is selected automatically based on usage data
  A. A fault domain is a grouping of hardware and infrastructure within an availability domain
  B. Each availability domain contains three fault domains

  ---

  References:

  A fault domain is a grouping of hardware and infrastructure within an availability domain. Each availability domain contains three fault domains. Fault domains provide anti-affinity: they let you distribute your instances so that the instances are

  not on the same physical hardware within a single availability domain.

• Question 120:

  Which statement is true about cloning a volume?

  A. You need to detach a volume before cloning from it.
  B. A cloned volume is the same as a snapshot that has a dependency on the source volume.
