A. Publish all events in a specific compartment to Oracle Streaming service for later analysis.
B. Triggers Function using Oracle Functions when new files are uploaded in an OCI Object Storage bucket.
C. Publish a notification when long lived tasks complete, such as OCI Autonomous Database backup completion.
D. Capture Monitoring Alarms and invoke Autoscaling of compute instances.
E. Trigger a notification when a function completes its execution.
Correct Answer: D
Question 2:
An organization has its IT infrastructure in a hybrid setup with an on-premises environment and an Oracle Cloud Infrastructure (OCI) Virtual Cloud Network (VCN) in the us-phonix-1 region. The on-premise applications communications with compute instances inside the VPN over a hardware VPN connection.
They are looking to implement an Intrusion detected and Prevention (IDS/IPS) system for their OCI environment. This platform should have the ability to scale to thousands of compute of instances running inside the VCN.
How should they architect their solution on OCI to achieve this goal?
A. Setup an OCI Private Load Balance! and configure IDS/IPS related health checks at TCP and/or HTTP level to inspect traffic
B. Configure each host with an agent that collects all network traffic and sends that traffic to the IDS/IPS platform to inspection
C. There Is no need to implement an IPS/IDS system as traffic coming over IPSec VPN tunnels Is already encrypt
D. Configure autoscaling on a compute Instance pool and set vNIC to promiscuous mode to called traffic across the vcn and send it IDS/IPS platform for inspection.
Correct Answer: B
in Transit routing through a private IP in the VCN you set up an instance in the VCN to act as a firewall or intrusion detection system to filter or inspect the traffic between the on- premises network and Oracle Services Network.
The Networking service lets you implement network security functions such as intrusion detection, application-level firewalls In fact, the IDS model can be host-based IDS (HIDS) or network- based IDS (NIDS). HIDS is installed at a host to
periodically monitor specific system logs for patterns of intrusions. In contrast, an NIDS sniffs the traffic to analyze suspicious behaviors. A signature-based NIDS (SNIDS) examines the traffic for patterns of known intrusions. SNIDS can
quickly and reliably diagnose theattacking techniques and security holes without generating an over-whelming number of false alarms because SNIDS relies on known signatures.
However, anomaly-based NIDS (ANIDS) detects unusual behaviors based on statistical methods. ANIDS could detect symptoms of attacks without specific knowledge of details. However, if the training data of the normal traffic are
inadequate, ANIDS may generate a large number of false alarms.
Question 3:
An online Stock trading application is deployed to multiple Availability Domains in the us phoenix-1 region. Considering the high volume of transactions that the trading application handles, the company has hired you to ensure that the data stored by the application available, and disaster resilient.
In the event of failure, the Recovery lime Objective (UK)) must be less than 2 hours to meet regulator requirements. Which Disaster Recovery strategy should be used to achieve the RTO requirement In the event of system failure?
A. Configure hourly block volumes backupsthrough the Storage Gateway service.
B. Configure hourly block volumes backups using the Oracle Cloud Infrastructure (OCI) Command Line Interface (CLI)
C. Store hourly block volumes backup to NVMe device under a compute instance and generate a custom Image every 5 minutes.
D. Configure your application to use synchronous master slave data replication between Availability Domains.
Correct Answer: B
You can use theCLI, REST APIs, or the SDKs to automate, script, and manage volume backups and their lifecycle. Planning Your Backup The primary use of backups is to support business continuity, disaster recovery, and long- term archiving requirements.
When determining a backup schedule, your backup plan and goals should consider the following: Frequency:How often you want to back up your data. Recovery time:How long you can wait for a backup to be restored and accessible to the applications that use it.
The time for a backup to complete varies on several factors, but it will generally take a few minutes or longer,depending on the size of the data being backed up and the amount of data that has changed since your last backup.
Number of stored backups:How many backups you need to keep available and the deletion schedule for those you no longer need. You can only create one backup at a time, so if a backup is underway, it will need to complete before you can create another one. For details about the number of backups you can store
Question 4:
You have deployed a multi-tierapplication with multiple compute instances in Oracle Cloud Infrastructure. You want to back up these volumes and have decided to use Volume Group\’s feature. The Block volume and Compute instances exist in different compartments within your tenancy.
Periodically. a few child compartments are moved under different parent compartments, and you notice that sometimes volume group backup fails.
What could be the cause?
A. You are exceeding your volume group backup quota configured.
B. You have the same block volume attached to multiple compute instances; if these compute instances are in different compartments then all concerned compartments must be moved at the same time.
C. Compute instance with multiple block volumes attached cannot move when a compartment is moved.
D. The Identity and Access Management policy allowing backup failed to move when the compartment was moved.
Correct Answer: D
You can move a compartment to a different parent compartment within the same tenancy. When you move a compartment, all its contents (subcompartments and resources) are moved with it. Moving a compartment has implications for the
contents. After you move a compartment to a new parent compartment, the access policies of the new parent take effect and the policies of the previous parent no longer apply. Before you move a compartment, ensure that:
You are aware of the policies that govern access to the compartment in its current position. You are aware of the polices in the new parent compartment that will take effect when you move thecompartment.
In some cases, when moving nested compartments with policies that specify the hierarchy, the polices are automatically updated to ensure consistency.
Question 5:
As a part of migration exercise for an existing on premises application to Oracle Cloud Infrastructure (OCT), yon ore required to transfer a 7 TB file to OCI Object Storage. You have decided to upload functionality of Object Storage. Which two statements are true?
A. Active multipart upload can be checked by listing all parts that have been uploaded, however It Is not possible to list information for individual object part in an active multipart upload
B. It is possible to spill this fileInto multiple parts using the APIs provided by Object Storage.
C. It is possible to split this file into multiple parts using rclone tool provided by Object Storage.
D. After initiating a multipart upload by making a CreateMultlPartUpload RESI API Call, the upload remains active until you explicitly commit it or abort.
E. Contiguous numbers need to be assigned for each part so that Object Storage constructs the object by ordering, part numbers in ascending order
Correct Answer: AD
You can check on anactive multipart upload by listing all parts that have been uploaded. (You cannot list information for an individual object part in an active multipart upload.)
After you finish creating object parts, initiate a multipart upload by making a CreateMultipartUpload REST API call. Provide the object name and any object metadata. Object Storage responds with a unique upload ID that you must include in any requests related to this multipart upload.
Object Storage also marks the upload as active.The upload remains active until you explicitly commit it or abort it.
Question 6:
You have an application running in Microsoft Azure and want to use Oracle Autonomous Data warehouse (ADW) instance for running business analytics.
How can you build a secure solution for such a use-case?
A. Connect the Oracle ADW in your VCN to the Microsoft Azure VNet over the internet.
B. Create a software VPN connection between Oracle Cloud Infrastructure (OCI) Virtual Cloud Network (VCN) and Microsoft Azure Virtual Network (VNet) and connect the application with Oracle ADW instance.
C. Setup an interconnect between OCI and Microsoft Azure using FastConnect and ExpressRoute. Use a Service Gateway in OCI Virtual Cloud Network to provide connectivity to the Oracle ADW instance for the application in Microsoft Azure VNet.
D. Create a software Remote Peering Connection between Oracle Cloud Infrastructure (OCI) Virtual Cloud Network (VCN) and Microsoft Azure Virtual Network (VNet) and connect the application with Oracle ADW instance.
Correct Answer: C
Question 7:

Question 8:
You are tasked with building a highly available, fault tolerant web application for your current employer. The security team is concerned about an increase in malicious web- based attacks across the internet and asked what you can do to add ahigher level of security to the website.
How should you architect the solution on Oracle Cloud Infrastructure (OCI) to meet all requirements defined by your organization? (Choose the best answer.)
A. Deploy at least 3 web application servers, each in a different fault domain, using a regional private subnet. Place a public load balancer in a regional public subnet and create a backend set for all of the web application servers. Deploy a Web Application Firewall (WAF) and configure the load balancer publicIP address as the origin.
B. Deploy at least 3 web application servers, each in a different fault domain, using a regional private subnet. Place a public load balancer in a regional public subnet and create a backend set for all of the web application servers. Create a Geolocation steering policy in Traffic Management and add an answer pool that directs to the public IP address of the load balancer. Configure a global catch-all rule to use this answer pool.
C. Deploy at least 3 web application servers, eachin a different fault domain, using a regional public subnet. Ensure that each web application server is assigned a public IP address. Deploy a Web Application Firewall (WAF) and configure one Origin for each public IP address.
D. Deploy at least 3 webapplication servers, each in a different fault domain, using a regional public subnet. Use the OCI Traffic Management service to create a load balancing policy that will resolve DNS evenly between all web servers.
Correct Answer: A
Question 9:
You have designed and deployed your Autonomous Data Warehouse (ADW) such that it is accessible from your on-premises data center and servers running on both private and public networks in Oracle Cloud Infrastructure (OCI).
As you are testing the connectivity to your ADW database from the different access paths, you notice that the server running on the private network is unable to connect to ADW.
Which two stepsdo you need to take to enable connectivity from the server on the private network to ADW? (Choose two.)
A. Add an entry in the Security List of the ADW allowing ingress traffic for C10R block 10.2.2.0/24
B. Add an entry in the route table (associated withthe private subnet) with destination of 0.0.0.0/: target type of NAT Gateway, add a stateful egress rule to the security list (associated with the private subnet) with destination of 0.0.0.0./0 and for all IP protocols.
C. Add an entry in the access tablelist of ASW for CIDR block 10.2.2.0/24.
D. Add an entry in the route table (associated with the private subnet) with destination of 0.0.0.0./0; target type of internet Gateway, add a stateful egress in the security list (associated with the private subnet) with destination of 0.0.0.0/0 and for all IP protocols.
E. Add an entry in the access control list of ADW for IP address 129.146.160.11
Correct Answer: BE
There are 3 connections to ADW 1- Connecting to (ADW) from Public Internet 2- Connecting to ADW (via NATor Service Gateway) from a server running on a private subnet in OCI (in the same tenancy) 3- Connecting to ADW (via internet Gateway) from a server running on a public subnet in OCI (in the same tenancy
Question 10:
You have multiple IAM users who launch different types of compute Instances and block volumes every day. As a result, your Oracle cloud Infrastructure (OCF) tenancy quickly hit the service limit and you can no longer create any new instances. As you are cleaning up environment, you notice that the majority of the Instances and block volumes are untagged. Therefore, It is difficult to pinpoint the owner of these resources verify if they are safe to terminate.
Because of this, your company has issued a new mandate, which requires adding compute instances.
Which option is the simplest way to implement this new requirement?
A. Create a policy to automatically tag a resource with the user name.
B. Create a policy using IAM requiring users to tag specific resources.This will allow a user to launch compute instances on\y if certain tags were defined.
C. Create tag variables to automatically tag a resource with the user name.
D. Create a default tag for each compartment, which ensure that appropriate tags are applied at resource creation
E. Create tag variables for each compartment to automatically tag a resource with the user name.
Correct Answer: C
Tag Variables You can use a variable to set the value of a defined tag. When you add the tag to a resource, the variable resolves to the data it represents. You can use tag variables in defined tags and default tags. Supported Tag Variables The following tag variables are supported. ${iam.principal.name}The name of the principal that tagged the resource ${iam.principal.type}Thetype of principal that tagged the resource. ${oci.datetime}The date and time that the tag was created.
Consider the following example: Operations.CostCenter=”${iam.principal.name}at${oci.datetime}” Operations is the namespace, CostCenter is the tag key, and the tag value contains two tag variables${iam.principal.name}and${oci.datetime}. When you add this tag to a resource, the variable resolves to your user name (the name of the principal that applied the tag) and a time date stamp for when youadded the tag. user_name at 2019-06-18T18:00:57.604Z
The variable is replaced with data at the time you apply the tag. If you later edit the tag, the variable is gone and only the data remains. You can edit the tag value in all the ways you would edit anyother tag value. To create a tag variable, you must use a specific format. ${}Type a dollar sign followed by open and close curly brackets.
The tag variable goes between the curly brackets. You can use tag variables with other tag variables andwith string values. Tag defaults let you specify tags to be applied automatically to all resources, at the time of creation, in a specificcompartment.This feature allows you to ensure that appropriate tags are applied at resource creation without requiring the user who is creating the resource to have access to the tag namespaces. https://docs.cloud.oracle.com/en-us/iaas/Content/Tagging/Tasks/managingtagdefaults.htm
Question 11:
You want to automate the processing of new Image files to generate thumbnails. the expected rate is 10 new files every hour. Which of the following is the most cost effective option to meet thisrequirement in Oracle Cloud Infrastructure (OCI)?
A. Upload files to an OCI Object storage bucket. Every time a file is uploaded, an event is emitted. Write a rule to filter these events with an action to trigger a function in Oracle Functions. The function processes the image in the file and stores the thumbnails back in an Object storage bucket.
B. Upload files to an OCI Object storage bucket. Every time a file is uploaded, trigger an event with an action to provision a compute instance with a cloud-init script to access the file, process it and store it back in an Object storage bucket. Terminate the instance using Autoscaling policy after the processing is finished.
C. Build a web application to ingest the files and save them to a NoSQL Database. Configure OCI Events service to trigger a notification using Oracle Notification Service (ONS). ONS invokes a custom application to process the image files to generate thumbnails. Store thumbnails in a NoSQL Database table.
D. Upload all files to an Oracle Streaming Service (OSS) stream. Set up a cron job to invoke a function in Oracle Functions to fetch data from the stream. Invoke another function to process the image files and generate thumbnails. Store thumbnails in another OSS stream.
Correct Answer: A
You can invoke a function that you\’ve deployed to Oracle Functions by triggered by an event in the Events service when update the Object storage to fetch the data then the function can process the File and store back to Object storage
Question 12:
You notice that a majority of your Oracle Cloud Infrastructure (OCI) resources like compute instances, block volumes, and load balancers are not tagged. You have received a mandate from your CIO to add a predefined set of tags to identify owners for respective OCI resources. E.g.if Chris and Larry each create compute instances in a compartment, the instances that Chris creates include tags that contain his name as the value, while the instances that Larry creates have his name.
Which option is the simplest way to implement this new tagging requirement?
A. Create a default tag for each compartment, which ensure that appropriate tags are applied at the time of resource creation.
B. Create an OCI Identity and Access Management policy requiring users to tag resources with their username.
C. Create an OCI Identity and Access Management policy to automatically tag a resource with the user name.
D. Create tag variables to automatically tag a resource with the user name.
Correct Answer: D
