• Question 2:

  Which two statements are true about Oracle Cloud Infrastructure Compute Service? (Choose two.)

  A. You can launch a virtual or bare metal instance by using the same LaunchInstance API.
  B. You cannot launch a bare metal server in Oracle Cloud Infrastructure Compute Service.
  C. You can attach a block volume in an Availability Domain other than your compute instance.
  D. You can share custom images across tenancies and regions.
  A. You can launch a virtual or bare metal instance by using the same LaunchInstance API.
  D. You can share custom images across tenancies and regions.

  Regions and Availability Domains

  Volumes are only accessible to instances in the same availability domain . You cannot move a volume between availability domains or regions.

• Question 3:

  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 4:

  Your application consists of three Oracle Cloud Infrastructure compute instances running behind a public load balancer. You have configured the load balancer to perform health checks on these instances, but one of the three instances fails to pass the configured health check. Which of the following action will the load balancer perform?

  A. Stop sending traffic to the instance that failed health check
  B. Terminate the instance that failed health check
  C. Stop the instances that failed health check
  D. Remove the instance that failed the health check from the backend set
  A. Stop sending traffic to the instance that failed health check

  ---

  health check A test to confirm the availability of backend servers. A health check can be a request or a connection attempt. Based on a time interval you specify, the load balancer applies the health check policy to continuously monitor

  backend servers. If a server fails the health check, the load balancer takes the server temporarily out of rotation. If the server subsequently passes the health check, the load balancer returns it to the rotation.

  You configure your health check policy when you create a backend set. You can configure TCP-level or HTTP-level health checks for your backend servers.

  -

  TCP-level health checks attempt to make a TCP connection with the backend servers and validate the response based on the connection status.

  -

  HTTP-level health checks send requests to the backend servers at a specific URI and validate the response based on the status code or entity data (body) returned. The service provides application-specific health check capabilities to help you increase availability and reduce your application maintenance window.

• Question 5:

  What is the maximum number of security lists that can be associated with a subnet?

  A. four
  B. three
  C. five
  D. two
  C. five

  ---

  you may optionally specify one or more security lists for the subnet to use (up to five). If you don't specify any, the subnet uses the cloud network's default security list. You can change which security list the subnet uses at any time. https://docs.cloud.oracle.com/iaas/Content/Network/Tasks/managingVCNs.htm

• Question 6:

  Which two configuration formats does Terraform support? (Choose two.)

  A. YAML
  B. JSON
  C. HCL
  D. XML
  B. JSON
  C. HCL

  ---

  References:

  Terraform configuration files can use either of two formats: Terraform domain-specific language (HashiCorp Configuration Language format [HCL]), which is the recommended approach, or JSON format if the files need to be machine

  readable.

• Question 7:

  You have an application running on Oracle Cloud Infrastructure. You identified that the read and write operations are slowing your application down enough to impair user access. The application is currently using a VM.Standard 1.2 compute without any block storage attached to it. Which two options allow you to increase disk performance? (Choose two.)

  A. Terminate the compute instance preserving the boot volume. Create a new compute instance using a VM Dense IO shape using the boot volume preserved.
  B. Terminate the compute instance preserving the boot volume. Create a new compute instance using a VM Standard shape and attach a new block volume to host your application.
  C. Create a backup of the boot volume. Create a new compute instance using a VM Dense IO shape and restore the backup.
  D. Terminate the compute instance and create a backup of the boot volume. Create a new compute instance using a VM Dense IO shape and restore the backup.
  A. Terminate the compute instance preserving the boot volume. Create a new compute instance using a VM Dense IO shape using the boot volume preserved.
  B. Terminate the compute instance preserving the boot volume. Create a new compute instance using a VM Standard shape and attach a new block volume to host your application.

  ---

  You can permanently terminate (delete) instances that you no longer need.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.

  You can use a boot volume backup to create an instance or you can attach it to another instance as a data volume. However before you can use a boot volume backup, you need to restore it to a boot volume.

• Question 8:

  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 9:

  Which three must be configured for a load balancer to accept incoming traffic? (Choose two.)

  A. a listener
  B. a back-end server
  C. a back end set
  D. a security list that is open on a listener port
  E. a certificate
  A. a listener
  B. a back-end server
  C. a back end set

  The essential components for load balancing include:

  ?A load balancer with pre-provisioned bandwidth.

  ?A backend set with a health check policy. See Managing Backend Sets. ?Backend servers for your backend set. See Managing Backend Servers. ?One or more listeners . See Managing Load Balancer Listeners. ?Load balancer subnet

  security rules to allow the intended traffic. To learn more about these rules, see Security Rules.

  ?Optionally, you can associate your listeners with SSL server certificate bundles to manage how your system handles SSL traffic. See Managing SSL Certificates

• Question 10:

  You deployed a database on a Standard Compute instance in Oracle Cloud Infrastructure (OCI) due to cost concerns. The database requires additional storage with high I/O and you decided to use OCI Block Volume service for it. With this requirement in mind, which elastic performance option should you choose for the Block Volume?

  A. Balanced Performance
  B. Higher performance
  C. Extreme performance
  D. Lower cost
  B. Higher performance
