• Question 81:

  Which two statements are true about restoring a block volume from a manual or policy-based block volume backup? (Choose two.)

  A. It can be restored as new volumes with different sizes from the backups

  B. It can be restored as a new volume to any AD across different regions

  C. It must be restored as a new volume to the same availability domain (AD) on which the original block volume backup resides

  D. It can be restored as a new volume to any AD in the same region

  Correct Answer: AD

  A ?Backups are encrypted and stored in Oracle Cloud Infrastructure Object Storage, and can be restored as new volumes to any availability domain within the same region they are stored. D- You can restore a block volume backup to a larger volume size. To do this, check Custom Block Volume Size (GB), and then specify the new size. You can only increase the size of the volume, you cannot decrease the size.

• Question 82:

  You currently manage an e-commerce application that utilizes 25 identical compute resources to handle customer traffic. The stakeholders have asked you to create another 25 identical compute resources in order to deploy and test a new version of the software? What is the most efficient process to create 25

  additional compute resources that are identical to the first 25?

  A. Create a custom image from 1 of the 25 servers. Use this custom image to provision 25 more servers

  B. Create a manual backup of each boot volume belonging to the 25 servers. Restore each backup to create 25 new boot volumes, from which you will provision 25 more servers

  C. Provision a new server and configure it to be identical to the first 25. Create a custom image from the new server, then use the custom image to provision 24 more servers

  D. Clone the boot volume of 1 of the 25 servers. Use the boot volume clone to provision 25 more servers

  Correct Answer: A

• Question 83:

  You deployed a web server in Oracle Cloud Infrastructure using an ephemeral public IP. After a few

  changes in your web server configuration, you rebooted the server and a new public IP was associated to

  your instance.

  What should you do to prevent this from happening again?

  A. Create a reserved public IP and associate it with the security list that your complete instance is using

  B. Create a reserved public IP and associate it with the subnet of your compute instance

  C. Create a reserved public IP and associate it with the VNIC of your compute instance

  D. Create a reserved public IP and associate it with the hosts file of your web server

  Correct Answer: C

  A public IP address is an IPv4 address that is reachable from the internet. If a resource in your tenancy

  needs to be directly reachable from the internet, it must have a public IP address. Depending on the type

  of resource, there might be other requirements.

  There are two types of public IPs:

  Ephemeral: Think of it as temporary and existing for the lifetime of the instance. Reserved: Think of it as

  persistent and existing beyond the lifetime of the instance it's assigned to. You can unassign it and then

  reassign it to another instance whenever you like. Exception: reserved public IPs on public load balancers.

  To create a new reserved public IP in your pool

  Confirm you're viewing the region and compartment where you want to create the reserved public IP.

  Open the navigation menu. Under Core Infrastructure, go to Networking and click Public IPs.

  Click Create Reserved Public IP.

  Enter the following:

  Name: An optional friendly name for the reserved public IP. The name doesn't have to be unique, and you

  can change it later. Avoid entering confidential information.

  Compartment: Leave as is.

  Tags:Optionally, you can apply tags. If you have permissions to create a resource, you also have

  permissions to apply free-form tags to that resource. To apply a defined tag, you must have permissions to

  use the tag namespace. For more information about tagging, see Resource Tags. If you are not sure if you

  should apply tags, skip this option (you can apply tags later) or ask your administrator.

  Click Create Reserved Public IP.

  To assign a reserved public IP to a private IP

  Prerequisite: The private IP must not have an ephemeral or reserved public IP already assigned to it. If it

  does, first delete the ephemeral public IP, or unassign the reserved public IP. Confirm you're viewing the

  compartment that contains the instance with the private IP you're interested in.

  Open the navigation menu. Under Core Infrastructure, go to Compute and click Instances.

  Click the instance to view its details.

  Under Resources, click Attached VNICs.

  The primary VNIC and any secondary VNICs attached to the instance are displayed.

  Click the VNIC you're interested in.

  Under Resources, click IP Addresses.

  The VNIC's primary private IP and any secondary private IPs are displayed. For the private IP you're

  interested in, click the Actions icon (three dots), and then click Edit. In the Public IP Address section, for

  Public IP Type, select the radio button for Reserved Public IP.

  Enter the following:

  Compartment: The compartment that contains the reserved public IP you want to assign. Reserved Public

  IP: The reserved public IP you want to assign. You have three choices:

  Create a new reserved public IP. You may optionally provide a friendly name for it. The name doesn't have

  to be unique, and you can change it later. Avoid entering confidential information. Assign a reserved public

  IP that is currently unassigned.

  Move a reserved public IP from another private IP.

  Click Update.

• Question 84:

  You have provisioned an Autonomous Data Warehouse (ADW) database with 16 enabled OCPUs and need to configure the consumer group for your application. Which two are true when deciding the number of sessions for each application? (Choose two.)

  A. The MEDIUM and LOW consumer group can run up to 16 concurrent SQL statements if HIGH consumer group has 0 SQL statements

  B. The HIGH consumer group can run up to 16 concurrent SQL statements as long as MEDIUM and LOW consumer groups have 0 SQL statements

  C. The MEDIUM consumer group can run 20 concurrent SQL statements when HIGH consumer group has 0 SQL statements

  D. The HIGH consumer group can run up to 16 concurrent SQL statements in addition to 32 concurrent SQL statements in MEDIUM and LOW consumer group each

  E. The HIGH consumer group can run 3 concurrent SQL statements when MEDIUM consumer group has 0 SQL statements

  Correct Answer: CE

• Question 85:

  You are implementing Oracle Cloud Infrastructure (OCI) FastConnect to access OCI public access points

  (e.g.

  ?object storage). You want other Internet traffic from your on-premises environment to use your

  existing connection with your ISP.

  What is the correct way to establish OCI FastConnect to access these OCI public endpoints?

  A.

  Configure private peering on your FastConnect link. Redistribute BGP routes learned into your existing routing table and advertise a default from your network infrastructure to OCI.

  B.

  Configure private peering on your FastConnect link with a static route that points to OCI object storage service.

  C.

  Configure public peering on your FastConnect link with a static route that points to OCI object storage service.

  D.

  Configure public peering on your FastConnect link. Redistribute BGP routes learned into your existing routing table and advertise a specific route for your network infrastructure to OCI.

• Question 86:

  Where are DB Systems backups stored by default?

  A. ASM disk group

  B. locally attached NVMe on virtual machine

  C. block volume

  D. object storage on Oracle Cloud Infrastructure

  Correct Answer: D

• Question 87:

  You have an Oracle Cloud Infrastructure (OCI) load balancer distributing traffic via an evenly- weighted round robin policy to your backend web servers. You notice that one of your web servers is receiving more traffic than other web servers. How can you resolve this imbalance?

  A. Check security lists and route tables of your virtual cloud network (VCN) and fix any issues associated with the rules

  B. Create separate listeners for each backend web server

  C. Delete and re-create your OCI load balancer

  D. Disable session persistence on your backend set

  Correct Answer: D

  Session persistence is a method to direct all requests originating from a single logical client to a single backend web server. Backend servers that use caching to improve performance, or to enable log-in sessions or shopping carts, can benefit from session persistence

• Question 88:

  You want an Oracle Cloud Infrastructure (OCI) compute instance in your compartment to make API calls to

  other services within OCI without storing credentials in a configuration file.

  What do you need to do?

  A. Create a dynamic group with appropriate matching rules to include the instance, and reference this group in your IAM policy statement

  B. Instances cannot access services outside their compartment

  C. VM instances are treated as users. Create a user, assign the user to that VM instance, and reference the instance in your Identity and Access Management (IAM) policy statement

  D. By default, all VM instances are created with an instance principal. Reference this instance principal in your IAM policy statement

  Correct Answer: A

• Question 89:

  What is a valid option when exporting a custom image?

  A. object storage URL

  B. archive storage URL

  C. file storage service

  D. block volume

  Correct Answer: A

  You can use the Console or API to export images, and the exported images are stored in the Oracle Cloud Infrastructure Object Storage service. To perform an image export, you need write access to the Object Storage bucket for the image.

• Question 90:

  Your organization has deployed a large, complex application across multiple compute instances in Oracle

  Cloud Infrastructure (OCI). These compute instances also have block volume storage attached to them.

  You want to create a time consistent backup of these block volume storage.

  Which implementation strategy should be used?

  A. Create a manual backup of each volume

  B. Use scripts available in OCI to backup block volume storage

  C. Group volumes in a volume group first and then use available scripts in OCI

  D. Group volumes in a volume group and create a manual backup of the volume group

  Correct Answer: D

  The Oracle Cloud Infrastructure Block Volume service provides you with the capability to group together multiple volumes in a volume group. A volume group can include both types of volumes, boot volumes, which are the system disks for your Compute instances, and block volumes for your data storage. You can use volume groups to create volume group backups and clones that are point- in-time and crash-consistent. This simplifies the process to create time-consistent backups of running enterprise applications that span multiple storage volumes across multiple instances. You can then restore an entire group of volumes from a volume group backup. To create a backup of the volume group Open the navigation menu. Under Core Infrastructure, go to Block Storage and click Volumes Groups. In the Volume Groups list, click Create Volume Group Backup in the Actions menu for the volume group you want to create a backup for.
