• Question 102:

  Which is a customer's responsibility on an Oracle Cloud Infrastructure database?

  A. patching the database and OS

  B. creating the first default database on the DBCS server

  C. creating an ASM diskgroup for data file or temp file storage

  D. installing the operating system (OS), Grid Infrastructure, and database software

  Correct Answer: A

  On autonomous there's no patching needed. But on the regular DB Cloud services you need to patch the DB and the OS. During the creation on the OCDB the first DB is created automatically Oracle automatically takes care of Operating system Installation/Configuration, Grid Infrastructure, ASM diskgroup Creation/ Configuration , and database software Installation and first database on the DB System. that's all when Creating DB Systems. and then the customer responsible to apply the patches to the database and OS

• Question 103:

  Your company has decided to move a few applications to Oracle Cloud Infrastructure and you have been asked to design it for Disaster Recovery (DR). One of the items of your design is to deploy the DR at least 300 miles from the home site and minimize the network latency as much as possible. Based on that, what will be the recommended deployment?

  A. Deploy applications in two separated VCNs in different Availability Domains and use VCN Remote Peering

  B. Deploy applications in different regions and have them connected using VCN Remote Peering

  C. Deploy applications in two separated VCNs in different regions and use VCN Local Peering

  D. Deploy applications on the same region splitting workloads across Availability Domains.

  Correct Answer: B

• Question 104:

  You are an administrator with an application running on OCI. The company has a fleet of OCI compute virtual instances behind an OCI Load Balancer. The OCI Load Balancer Backend Set health check API is providing a `Critical' level warning. You have confirmed that your application is running healthy on the backend servers. What is the possible reason for this `Critical' warning?

  A. A user does not have correct IAM credentials on the Backend Servers.

  B. The Backend Server VCN's Route Table does not include the route for OCI LB.

  C. OCI Load Balancer Listener is not configured correctly.

  D. The Backend Server VCN's Security List does not include the IP range for the source of the health check requests.

  Correct Answer: D

  References:

  "In this case, your security rules might not include the IP range for the source of the health check requests.

  You can find the health check source IP on the Details page for each backend server. You can also use

  the API to find the IP in the sourceIpAddress field of the HealthCheckResult object." https:// docs.cloud.oracle.com/iaas/Content/Balance/Tasks/editinghealthcheck.htm#health-status

• Question 105:

  Which two resources are available by default when your Oracle Cloud Infrastructure tenancy is provisioned?

  A. an NVMe SSD boot disk for each instance, whose size is determined by the image and shape of the instance

  B. a range of public IP addresses that are reserved for your tenancy

  C. a set of images, where each image is a template of a virtual hard drive that consists of the OS and installed software and applications

  D. a variety of shapes, where each shape determines the number of CPUs and memory allocated to an instance.

  Correct Answer: CD

• Question 106:

  Your company is moving an Internet-facing, 2-tier web application into Oracle Cloud Infrastructure. The application must have a highly available architecture. Which two design options would you consider? (Choose two.)

  A. Configure a Dynamic Route Gateway in your VCN and make it highly available.

  B. Configure a NAT instance in your Virtual Cloud Network (VCN). Create a route rule by using the private IP of the NAT instance as a route target for all the private subnets in your VCN.

  C. Create an Internet Gateway and attach it to your VCN. Deploy public load balancer nodes into two Available Domains.

  D. Place all web servers behind a public load balancer.

  Correct Answer: CD

• Question 107:

  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.

  Correct Answer: BC

  References: https://cloud.oracle.com/database/faq#backup 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 108:

  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.

  Correct Answer: A

• Question 109:

  There are multiple options of migrating Oracle Databases from on-premises to Oracle Cloud Infrastructure. Which two characteristics do you need to consider when choosing a migration method? (Choose two.)

  A. On-premises database character set and application version

  B. On-premises database version and quantity of data, including indexes

  C. On-premises host operating system platform and network bandwidth D. On-premises connectivity using remote and local VCN peering

  Correct Answer: BC

  References: https://docs.cloud.oracle.com/iaas/Content/Database/Tasks/migrating.htm Some of the characteristics and factors to consider when choosing a migration method are: On-premises database version Database service database version On-premises host operating system and version On-premises database character set Quantity of data, including indexes Data types used in the on-premises database Storage for data staging Acceptable length of system outage Network bandwidth

• Question 110:

  When terminating a compute instance, which statement is true?

  A. The instance needs to be stopped first, and then terminated.

  B. The boot volume is always deleted.

  C. All block volumes attached to the instance are terminated.

  D. Users can preserve the boot volume associated with the instance.

  Correct Answer: D

  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.
