• Question 183:

  Which statement is true about DB Systems?

  A. Data Guard as a Service is offered between regions.
  B. You cannot manage the database as sys/sysdba.
  C. You have full control over the automatic backup schedule and retention periods.
  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 184:

  You need to set up instance principals so that an application running on an instance can call Oracle Cloud Infrastructure (OCI) public services, without the need to configure user credentials. A developer in your team has already configured

  the application built using an OCI SDK to authenticate using the instance principals provider.

  Which is NOT a necessary step to complete this set up?

  A. Create a dynamic group with matching rules to specify which instances you want to allow to make API calls against services.
  B. Generate Auth Tokens to enable instances in the dynamic group to authenticate with APIs.
  C. Create a policy granting permissions to the dynamic group to access services in your compartment or tenancy.
  D. Deploy the application and the SDK to all the instances that belong to the dynamic group.
  D. Deploy the application and the SDK to all the instances that belong to the dynamic group.

• Question 185:

  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 186:

  An instance is launched with a primary VNIC that is created during instance launch. Which two operations are true when you add secondary VNICs to an existing instance? (Choose two.)

  A. You can remove the primary VNIC after the secondary VNIC's attachment is complete.
  B. You can remove the secondary VNIC later if it is not needed.
  C. The primary and secondary VNIC association should be within the same Availability Domain.
  D. It is not possible to connect two VNICs to an instance.
  B. You can remove the secondary VNIC later if it is not needed.
  C. The primary and secondary VNIC association should be within the same Availability Domain.

• Question 188:

  Which two statements about Oracle Cloud Infrastructure File Storage Service are accurate? (Choose two.)

  A. Customer can encrypt the communication to a mount target via export options.
  B. Mount targets use Oracle-managed keys by default.
  C. File systems use Oracle-managed keys by default.
  D. Customer can encrypt data in their file system using their own Vault encryption key.
  E. Communication with file systems in a mount target is encrypted via HTTPS.
  B. Mount targets use Oracle-managed keys by default.
  D. Customer can encrypt data in their file system using their own Vault encryption key.

• Question 189:

  Which two features are offered natively on Oracle Cloud Infrastructure Database Cloud Service (DBCS)? (Choose two.)

  A. Data Guard in Async mode within a region
  B. GoldenGate replication between two regions
  C. Data Guard in Maximum Protection mode
  D. backup to Object Storage
  A. Data Guard in Async mode within a region
  D. backup to Object Storage

  ---

  Data Guard in Maximum Performance protection mode is supported not simply Maximum Protection mode, however, you can configure additional protection modes and transport types by logging on to the DB system and accessing Data Guard command-line interface( DGMGRL).

• Question 190:

  Which statement is true about Oracle Cloud Infrastructure FastConnect?

  A. For private peering, FastConnect extends your existing infrastructure to allow you to consume object storage from your on-premises data center
  B. For private peering, FastConnect extends your existing infrastructure to a virtual cloud network
  C. The FastConnect provider network offers only 1 Gbps port connection speed increments
  D. For public peering, a dynamic routing gateway must be configured and attached to the virtual cloud network (VCN)
  B. For private peering, FastConnect extends your existing infrastructure to a virtual cloud network

  ---

  With FastConnect, you can choose to use private peering, public peering, or both. Private peering: To extend your existing infrastructure into a virtual cloud network (VCN) in Oracle Cloud Infrastructure (for example, to implement a hybrid cloud, or a lift and shift scenario). Communication across the connection is with IPv4 private addresses (typically RFC 1918). Public peering: To access public services in Oracle Cloud Infrastructure without using the internet. For example, Object Storage, the Oracle Cloud Infrastructure Console and APIs, or public load balancers in your VCN. Communication across the connection is with IPv4 public IP addresses. Without FastConnect, the traffic destined for public IP addresses would be routed over the internet.
