  A. Create resources in the right order without regard to the order in the terraform plan file.
  B. Automatically re-provision the resources that are tainted or whose configuration has changed.
  C. Automatically translate a deployed infrastructure and create a plan.

• Question 205:

  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 206:

  Where do you find the tnsnames.ora for your Autonomous Data Warehouse (ADW) database?

  A. You can download tnsnames.ora from Oracle Cloud Infrastructure web console under ADW details page
  B. The tnsnames.ora file is included in credentials.zip file that you download from service console of ADW
  C. The ADW database will place the tnsnames.ora file in an object storage bucket
  D. You are automatically prompted to download the tnsnames.ora file upon creation of the ADW database
  B. The tnsnames.ora file is included in credentials.zip file that you download from service console of ADW

  -From the Service Console click the Administration link.

  -Click Download Client Credentials (Wallet).

  -

  On the Download Client Credentials (Wallet) page, enter a wallet password in the Password field and confirm the password in the Confirm Password field. The password must be at least 8 characters long and must include at least 1 letter

  and either 1 numeric character or 1 special character. This password protects the downloaded Client Credentials wallet.

  -

  Click Download to save the client security credentials zip file. By default the filename is:

  Wallet_databasename.zip. You can save this file as any filename you want. You must protect this file to prevent unauthorized database access.

  The zip file includes the following:

  tnsnames.ora and sqlnet.ora: Network configuration files storing connect descriptors and SQL*Net client side configuration.

  cwallet.sso and ewallet.p12: Auto-open SSO wallet and PKCS12 file. PKCS12 file is protected by the wallet password provided in the UI.

  keystore.jks and truststore.jks: Java keystore and truststore files. They are protected by the wallet password provided while downloading the wallet.

  ojdbc.properties: Contains the wallet related connection property required for JDBC connection. This should be in the same path as tnsnames.ora.

• Question 207:

  Your application front end consists of several Oracle Cloud Infrastructure compute instances behind a public load balancer. You have configured the load balancer to perform health checks on these instances. What will happen if an instance fails to pass the configured health checks?

  A. The instance is replaced automatically by the load balancer.
  B. The instance is terminated automatically by the load balancer.
  C. The instance is taken out of the back end set by the load balancer.
  D. The load balancer stops sending traffic to that instance.
  D. The load balancer stops sending traffic to that instance.

  ---

  One or more of the backend servers reports as unhealthy. A backend server might be unhealthy or the health check might be misconfigured.

• Question 208:

  You have launched a compute instance running Oracle database in a private subnet in the Oracle Cloud Infrastructure US East region. You have also created a Service Gateway to back up the data files to OCI Object Storage in the same region. You have modified the security list associated with the private subnet to allow traffic to the Service Gateway, but your instance still cannot access OCI Object Storage. How can you resolve this issue?

  A. Add a stateful rule that enables ingress HTTPS (TOP port 443) traffic to 001 Object Storage in the security list associated with the private subnet
  B. Add a stateful rule that enables egress HTTPS (TCP port 443) traffic to OCI Object Storage in the security list associated with the private subnet
  C. Add a rule in the Route Table associated with the private subnet with Target type as "Service Gateway" and destination service as all IAD services in the Oracle Service Network.'
  D. Use the default Security List, which has ports open for OCI Object Storage
  C. Add a rule in the Route Table associated with the private subnet with Target type as "Service Gateway" and destination service as all IAD services in the Oracle Service Network.'

  ---

  A service gateway lets your virtual cloud network (VCN) privately access specific Oracle services without exposing the data to the public internet. No internet gateway or NAT is required to reach those specific services. The resources in the

  VCN can be in a private subnet and use only private IP addresses. The traffic from the VCN to the Oracle service travels over the Oracle network fabric and never traverses the internet.

  The service gateway is regional and enables access only to supported Oracle services in the same region as the VCN.

  For traffic to be routed from a subnet in your VCN to a service gateway, you must add a rule accordingly to the subnet's route table. The rule must use the service gateway as the target. For the destination, you must use the service CIDR label

  that is enabled for the service gateway. This means that you don't have to know the specific public CIDRs, which could change over time.

• Question 209:

  Within your tenancy you have a compute instance with a boot volume and a block volume attached. The boot volume contains the OS and the attached block volume contains the instance's important dat

  A. Logs on the boot volume have filled the boot volume and are causing issues with the OS. What should you do to resolve this situation?
  B. Stop the instance that is full. Create a manual backup of the block storage before making changes. Detach the block volume, create a new instance of the same shape with a larger custom boot volume and attach the block volume to the new instance. Configure the OS and any related application(s) to access the block volume under the same mount point as before.
  C. Create a new instance with a larger boot volume size as well a new block volume which is the same size or larger than the one attached to the full instance. rsync the state of the boot volume and the state of the block volume between the two instances.
  D. Detach the block volume from the full instance. Create a new instance of the same shape with a larger boot volume and rsync the state of the boot volume between the instances. Attach the block volume to the new instance.
  E. Create a manual backup of the block storage instance. Create a custom image of the full instance. Once that completes deploy the custom image to a new instance.
  A. Logs on the boot volume have filled the boot volume and are causing issues with the OS. What should you do to resolve this situation?
