• Question 22:

  You need to create a high performance shared file system, and have been advised to use file storage service (FSS). You have logged into the Oracle Cloud Infrastructure console, created a file system, and followed the steps to mount the

  shared file system on your Linux instance. However, you are still unable to access the shared file system from your Linux instance.

  What is the likely reason for this?

  A. There are no security list rules for mount target traffic
  B. There is no internet gateway (IGW) set up for mount target traffic
  C. There is no Identity and Access Management (IAM) policies set up to allow you to access the mount target
  D. There is no route in your virtual cloud network's (VCN) route table for mount target traffic
  A. There are no security list rules for mount target traffic

  ---

  Virtual firewall rules for your VCN. Your VCN comes with a default security list, and you can add more. These security lists provide ingress and egress rules that specify the types of traffic allowed in and out of the instances. You can choose whether a given rule is stateful or stateless. Security list rules must be set up so that clients can connect to file system mount targets. For more information about how security lists work in Oracle Cloud Infrastructure, see Security Lists in the Networking documentation. For information about setting up specific security list rules required for mount target traffic, see Configuring VCN Security List Rules for File Storage. About Security explains how security lists interact with other types of security in your file system. https://docs.cloud.oracle.com/iaas/Content/File/Concepts/filestorageoverview.htm

• Question 23:

  Which two options are true for Autonomous Transaction Processing (ATP) database? (Choose two.)

  A. You can add/remove Diskgroup in ATP
  B. You can scale storage up or down in ATP
  C. You can scale CPU up or down in ATP
  D. You can add more Pluggable Database for consolidating multiple databases in ATP
  E. You can add new ORACLE_HOME for bringing older versions of on-premises databases to ATP
  B. You can scale storage up or down in ATP
  C. You can scale CPU up or down in ATP

  ---

  You can scale up/down your Autonomous Database to scale both in terms of compute and storage only when needed, allows people to pay per use.

  Oracle allows you to scale compute and storage independently, no need to do it together. these scaling activities fully online (no downtime required) in Details page Autonomous Database click Scale Up/Down. Click on arrow to select a value

  for CPU Core Count or Storage (TB).

  Or Select auto scaling to allow the system to automatically use up to three times more CPU and IO resources to meet workload demand, compared to the database operating with auto scaling disabled.

• Question 24:

  You have two NFS clients running in two different subnets within the same Oracle Cloud Infrastructure (OCI) Virtual Cloud Network (VCN). You have created a shared file system for the two NFS clients who want to connect to the same file system, but you want to restrict one of the clients to have READ access while the other has READ/Write access. 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.

• Question 25:

  Which service would you use if your big data workload required shared access and NFS-based connectivity?

  A. block volume
  B. archive storage
  C. object storage
  D. file storage
  D. file storage

• Question 26:

  As an Oracle Cloud Infrastructure tenancy administrator, you created predefined lists of values and associated them with tag key definitions.

  One of the users in your tenancy complains that she cannot see these predefined values.

  What is causing this issue?

  A. The user is trying to use free-form tags.
  B. Some of the predefined values are null.
  C. The user is not part of an Identity and Access Management group that gives access to tagging.
  D. The user has breached either the quota or service limit for using tags.
  A. The user is trying to use free-form tags.

• Question 27:

  You have just created an Autonomous Data Warehouse (ADW) and you want to connect to the ADW using SQL Developer. What three items are needed to connect to the ADW using SQL Developer? (Choose three.)

  A. the keystore password
  B. a security list with an ingress rule for TCP port 1521
  C. the client credentials file
  D. the public IP address of the ADW server
  E. the admin password
  A. the keystore password
  C. the client credentials file
  E. the admin password

• Question 28:

  You developed a microservices based application that runs on Oracle Cloud Infrastructure (OCI) Container Engine for Kubernetes (OKE). You want to provide access to this cluster to other team members. What should you do to provide access to this cluster using as fewest steps as possible?

  A. Create a group in OCI Infrastructure Access Management (IAM). Create a policy to grant access to the OKE cluster. Other team members should use OCI Cloud Shell to generate the kubeconfig into their own cloud shell environment and access the cluster using kubectl from cloud shell.
  B. Create a group in OCI Infrastructure Access Management (IAM). Create a policy to grant access to the OKE cluster. Create individual users and access token for each team member. Other team members should use OCI Cloud Shell to generate the kubeconfig into their own cloud shell environment and access the cluster using kubectl from cloud shell.
  C. Create a group in OCI Infrastructure Access Management (IAM). Create a policy to grant access to the OKE cluster. Create a cluster role and cluster role binding to provide access to the cluster for each team member. Other team members should install oci cli and kubectl locally on their laptop. Use the oci cli to generate the kubeconfig and use kubectl to access the cluster.
  D. Create a group in OCI Infrastructure Access Management (IAM). Create a policy to grant access to the OKE cluster. Other team members should install oci cli and kubectl locally on their laptop. Use the oci cli to generate the kubeconfig and use kubectl to access the cluster.
  B. Create a group in OCI Infrastructure Access Management (IAM). Create a policy to grant access to the OKE cluster. Create individual users and access token for each team member.

• Question 30:

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

  A. Snapshots are created under the root folder of file system, in a hidden directory named .snapshot
  B. Snapshots are not incremental
  C. You can restore the whole snapshot, but not the individual files
  D. It Is not possible to create snapshots from OCI console, but just the CLI
  A. Snapshots are created under the root folder of file system, in a hidden directory named .snapshot

  ---

  The File Storage service supports snapshots for data protection of your file system. Snapshots are a consistent, point-in-time view of your file systems. Snapshots are copy-on-write, and scoped to the entire file system. The File Storage

  service encrypts all file system and snapshot data at rest. You can take as many snapshots as you need.

  Data usage is metered against differentiated snapshot data. If nothing has changed within the file system since the last snapshot was taken, the new snapshot does not consume more storage Snapshots are accessible under the root

  directory of the file system at .snapshot/name. For data protection, you can use a tool that supports NFSv3 to copy your data to a different availability domain, region, file system, object storage, or remote location.
