NEW QUESTION # 22
When creating an Oracle Cloud Infrastructure (OCI) Virtual Cloud Network (VCN) with the VCN wizard, which THREE gateways are created automatically?
- A. Bastion Host
- B. Local Peering Gateway
- C. Internet Gateway
- D. Dynamic Routing Gateway
- E. Service Gateway
- F. Storage Gateway
- G. NAT Gateway
Answer: C,E,G
Explanation:
Explanation
Internet Gateway, NAT Gateway, and Service Gateway are three gateways that are created automatically when creating a VCN with the VCN wizard. An Internet Gateway allows public traffic between the VCN and the internet. A NAT Gateway allows private traffic from the VCN to access the internet without exposing the VCN resources to incoming internet connections. A Service Gateway allows private traffic from the VCN to access OCI services such as Object Storage, Email Delivery, and Notifications. The other options are not created automatically by the VCN wizard, but can be added manually later if needed. References: [VCN Wizard], [Gateways]
NEW QUESTION # 23
Which THREE protocols are supported by the Oracle Cloud Infrastructure (OCI) Network Load Balancer?
- A. TCP
- B. BGP
- C. HTTP
- D. UDP
- E. iSCSI
- F. ICMP
Answer: A,D,F
Explanation:
Explanation
The explanation is that the OCI Network Load Balancer supports three protocols: UDP, TCP, and ICMP.
These protocols are used to distribute traffic across multiple backend servers based on different criteria, such as source and destination IP addresses, ports, and ICMP types and codes.
NEW QUESTION # 24
As a network architect you have deployed a public subnet on your Virtual Cloud Network (VCN) with this security list:
You have also created a network security group (NSG) as shown in the table here, and assigned it to your bastion host:
You have confirmed that routing is correct but when you SSH to the VM from your home over the Internet youare unable to connect.
What could be the problem?
- A. Public subnet does not have a route rule to the Internet Gateway.
- B. Internet traffic should be allowed only on the NSG.
- C. SSH traffic is not allowed in the security list nor on the NSG from the Internet.
- D. User will be able to SSH to the VM from the Internet as SSH is open on the NSG.
Answer: C
Explanation:
Explanation
SSH traffic is not allowed in the security list nor on the NSG from the Internet is the correct answer. This is because the security list only allows ingress traffic from 10.0.0.24 on port 22, and the NSG only allows ingress traffic from 10.0.0.0/16 on port 22. Neither of them allows ingress traffic from 0.0.0.0/0 (the Internet) on port
22, which is required for SSH access. The other options are not correct, as they do not explain why SSH access is not possible. References: [Security Lists], [Network Security Groups]
NEW QUESTION # 25
You need to set up instance principals so that an application running on aninstance can call Oracle CloudInfrastructure (OCI) public services, without the need to configure user credentials.
A developer in your team has already configured the application built using an OCISDK to authenticate using theinstance principals provider.
Which is NOTa necessary step to complete this set up?
- A. Deploy the application and the SDK to all the instances that belong to the dynamic group.
- 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. Create a dynamic group with matching rules to specify which instances can make API calls against services.
Answer: B
Explanation:
Explanation
Generating Auth Tokens to enable instances in the dynamic group to authenticate with APIs is not a necessary step to complete this set up. This is because Auth Tokens are used to authenticate users, not instances, when making API calls to OCI services. Instance principals are a feature that allows instances to authenticate themselves using certificates, without requiring user credentials or Auth Tokens. The other options are necessary steps to complete this set up, as they enable instances in the dynamic group to make API calls against services using instance principals and IAM policies. References: [Instance Principals], [Auth Tokens]
NEW QUESTION # 26
Which statement accurately describes the key features and benefits of OCI Confidential Computing?
- A. It encrypts and isolates in-use data and the applications processing that data, thereby preventing unauthorized access or modification.
- B. It optimizes network performance and reduces latency through advancedrouting algorithms and cachingmechanisms.
- C. It provides automatic scalability and load balancing capabilities, which allow seamless integration withother cloud providers.
- D. It enables users to securely store and retrieve data by using distributed file systems, ensuring high availability and fault tolerance.
Answer: A
Explanation:
Explanation
It encrypts and isolates in-use data and the applications processing that data, thereby preventing unauthorized access or modification is an accurate description of the key features and benefits of OCI Confidential Computing. Confidential Computing is a feature that leverages hardware-based Trusted Execution Environments (TEEs) to protect data and applications from unauthorized access or modification while they are in use by the CPU or memory. This adds an extra layer of security to cloud computing, as it protects data not only at rest and in transit, but also in use. The other options are not accurate descriptions of the key features and benefits of OCI Confidential Computing. References: [Confidential Computing]
NEW QUESTION # 27
You have a block volume created in the US West (Phoenix) region. You enabled Cross Region Replication for thevolume and selected US West (San Jose) as the destination region. Now, you would like to create a new volumefrom the volume replica in the US West (San Jose) region.
What should you do?
- A. Initiate the replica.
- B. Activate the replica.
- C. No action required. By default, the replica is available as a block volume.
- D. Trigger the replica.
Answer: B
Explanation:
Explanation
The explanation is that when you enable Cross Region Replication for a block volume, Object Storage creates a replica of the volume in another region of your choice. The replica is not available as a block volume until you activate it. To activate a replica, you need to select the replica from the Block Storage console and click Activate Replica. This will create a new block volume from the replica in the destination region.
NEW QUESTION # 28
You are a security administrator for your company's Oracle Cloud Infrastructure (OCI) tenancy. Your storage administrator informs you that she cannot associate an encryption key from an existing Vault to a new Object Storage bucket.
What could be a possible reason for this behavior?
- A. There is no Identity and Access Management (IAM) policy that allows the Object Storage service to use the key.
- B. The secret for the key was not created beforehand
- C. The storage administrator forgot to select "Encrypt using Oracle managed keys" while creating the bucket.
- D. The Object Storage bucket policy lacks the necessary Access Control List (ACL).
Answer: A
Explanation:
There is no Identity and Access Management (IAM) policy that allows the Object Storage service to use the key. The explanation is that when you create an Object Storage bucket with encryption using a customer-managed key from Vault, you need to have an IAM policy that allows the Object Storage service to use the key on your behalf. The policy should look like this:
allow service objectstorage-<region> to use key in compartment <compartment-name> where <region> is the region where your bucket resides and <compartment-name> is the compartment where your key resides.

- A. Configure one FastConnect virtual circuit to the us-ashburn-1 region andthe second FastConnect virtual circuit to the us-phoenix-1 region.
- B. Configure a Site-to-Site VPN from a single on-premises CPE.
- C. Configure one FastConnect virtual circuit to the us-ashburn-1 region and a Site-to-Site VPN to the usashburn-1 region.
- D. Configure two FastConnect virtual circuits to the us-ashburn-1 region and terminate them in diverse hardware on-premises.
Answer: C,D
Explanation:
Explanation
Configure two FastConnect virtual circuits to the us-ashburn-1 region and terminate them in diverse hardware on-premises. Configure one FastConnect virtual circuit to the us-ashburn-1 region and a Site-to-Site VPN to the us-ashburn-1 region. The explanation is that FastConnect is a service that provides a private and dedicated connection between your on-premises network and your VCN in OCI. FastConnect offers higher bandwidth, lower latency, and more consistent network performance than public internet connections. To create a fully redundant connection from your on-premises data center to your VCN in the us-ashburn-1 region, you can either configure two FastConnect virtual circuits to the same region and terminate them in diversehardware on-premises, or configure one FastConnect virtual circuit to the region and a Site-to-Site VPN to the same region as a backup option.

Which IAM Identity Domain type should you create?
- A. Oracle Apps Premium
- B. Premium
- C. External User
- D. Free
Answer: B
Explanation:
Premium is the IAM Identity Domain type that you should create if you want a full-featured IDaaS solution that helps you manage workforce authentication and access to all of your Oracle and non-Oracle applications. Premium Identity Domain provides users with access to Oracle Identity Cloud Service, which is an IDaaS solution that offers identity management, single sign-on, multifactor authentication, identity governance, and integration with third-party applications. The other options are not IAM Identity Domain types that provide a full-featured IDaaS solution. Reference: [Identity Domains], [Oracle Identity Cloud Service]
NEW QUESTION # 32
You just got a last minute request to create a set of instances in Oracle Cloud Infrastructure (OCI). The configuration and installed software are identical for every instance, and you already have a running instance in your OCI tenancy. Which image option allows you to achieve this task with the least amount of effort?
- A. Use Oracle-provided images and customize the installation using a third-party tool.
- B. Select an image from the OCI Marketplace.
- C. Create a custom image and use it as a template for the new instances.
- D. Bring your own image and use it as a template for the new instances.
Answer: C
Explanation:
Creating a custom image and using it as a template for the new instances is the option that allows you to achieve this task with the least amount of effort. A custom image is a copy of an existing instance that you can use to launch other instances with the same configuration and installed software. The other options are not suitable for this scenario, as they would require more time and effort to create and customize the instances. Reference: [Custom Images]
NEW QUESTION # 33
You have an instance running in Oracle Cloud Infrastructure (OCI) that cannot be live-migrated during an infrastructure maintenance event. OCI schedules a maintenance due date within 14 to 16 days and sends you a notification.
What would happen if you choose not to proactively reboot the instance before the scheduled maintenance due date?
- A. You will receive another notification to reboot within the next 14 days.
- B. The instance will get terminated.
- C. You will receive another notification to reboot within the next 7 days.
- D. The instance is either reboot-migrated or rebuilt in place for you.
Answer: D
Explanation:
If you choose not to proactively reboot the instance before the scheduled maintenance due date, the instance is either reboot-migrated or rebuilt in place for you. Reboot-migration is a process where OCI migrates your instance to a new physical host without changing its configuration or public IP address. Rebuild in place is a process where OCI shuts down your instance, performs maintenance on the physical host, and restarts your instance with the same configuration and public IP address. The other options are not correct. Reference: [Reboot-Migration], [Rebuild in Place]
NEW QUESTION # 34
Which is NOT a valid Oracle Cloud Infrastructure (OCI) Virtual Cloud Network (VCN) approach?
- A. Use OCI tags to tag VCN resources so that all resources follow organizational tagging/naming conventions.
- B. Ensure VCN CIDR prefix overlaps with other VCNs in your tenancy or withyour organizations private IPnetwork ranges.
- C. Ensure not all IP addresses are allocated at once within a VCN or subnet; instead reserve some IP addresses for future use.
- D. Private subnets should ideally have individual route tables to control the flowof traffic within and outsideof VCN.
Answer: B
Explanation:
Explanation
Ensure VCN CIDR prefix overlaps with other VCNs in your tenancy or with your organizations private IP network ranges. The explanation is that a VCN CIDR prefix is the range of IPv4 addresses that can be used within the VCN and its subnets. The VCN CIDR prefix should not overlap with other VCNs in your tenancy or with your organization's private IP network ranges, as this can cause routing conflicts and connectivity issues. You should choose a VCN CIDR prefix that is large enough to accommodate your current and future needs, but not too large to waste IP addresses. You can use any of the private IPv4 address ranges specified in RFC 1918 for your VCN CIDR prefix.
NEW QUESTION # 35
Which TWO statements about the Oracle Cloud Infrastructure (OCI) File Storage Service are accurate?
- A. Customer can encrypt data in their file system using their own Vault encryption key.
- B. Mount targets use Oracle-managed keys by default.
- C. File systems use Oracle-managed keys by default.
- D. Communication with file systems in a mount target is encrypted via HTTPS.
- E. Customer can encrypt the communication to a mount target via export options.
Answer: A,C
Explanation:
File systems use Oracle-managed keys by default. Customer can encrypt data in their file system using their own Vault encryption key. The explanation is that File Storage Service encrypts all data at rest using AES-256 encryption algorithm. By default, File Storage Service uses Oracle-managed keys to encrypt and decrypt data. However, you can also use your own Vault encryption key to encrypt data in your file system. To do so, you need to create a key in Vault and associate it with your file system when you create or update it.
NEW QUESTION # 36
What should be created before provisioning an Oracle Cloud Infrastructure (OCI) DB System?
- A. Virtual Cloud Network
- B. Compartment
- C. Bucket in Object Storage
- D. Compute Instance
Answer: A
Explanation:
Explanation
The explanation is that a Virtual Cloud Network (VCN) is a software-defined network that you set up in OCI to connect your cloud resources, such as compute instances and databases. A VCN provides you with complete control over your network environment, including selecting your own IP address range, creating subnets, route tables, gateways, security lists, etc. You need to create a VCN before provisioning an OCI DB System, as you need to specify which subnet in your VCN you want to launch your DB System in.
NEW QUESTION # 37
You plan to upload a large file (3 TiB) to Oracle Cloud Infrastructure (OCI) Object Storage. You would like tominimize the impact of network failures while uploading, and therefore you decide to use the multipart upload capability.
Which TWO statements are true about performing a multipart upload using the Multipart Upload API?
- A. While a multipart upload is still active, you can keep adding parts as long asthe total number is less than10,000.
- B. You do not need to split the object into parts. Object Storage splits the object into parts and uploads all ofthe parts automatically.
- C. You do not have to commit the upload after you have uploaded all the object parts.
- D. When you split the object into individual parts, each part can be as large as 50 GiB.
Answer: A,D
Explanation:
Explanation
While a multipart upload is still active, you can keep adding parts as long as the total number is less than
10,000. When you split the object into individual parts, each part can be as large as 50 GiB. The explanation is that a multipart upload allows you to upload a large object in parts, which can improve performance and reliability. You need to split the object into parts yourself and upload each part separately using the Multipart Upload API. You can add parts to an active multipart upload until you reach the maximum number of 10,000 parts per upload. Each part can range from 10 MiB to 50 GiB in size, except for the last part, which can be any size.
NEW QUESTION # 38
Which is NOT a valid option for an Oracle Cloud Infrastructure (OCI) compute shape?
- A. Bare Metal
- B. Dedicated Virtual Machine Host
- C. Virtual Machine
- D. Exadata Virtual Machine
Answer: D
Explanation:
Explanation
Exadata Virtual Machine is not a valid option for an OCI compute shape. Exadata Virtual Machine is a deployment option for Exadata Cloud Service or Exadata Cloud@Customer, which are services that provide dedicated Exadata infrastructure for running Oracle databases in OCI. Exadata Virtual Machine allows you to create multiple virtual machines on each Exadata compute node and isolate them from each other using Oracle VM technology. The valid options for OCI compute shapes are:
Bare Metal: A bare metal instance is a physical server that gives you direct access to the underlying hardware and full isolation from other tenants.
Dedicated Virtual Machine Host: A dedicated virtual machine host is a physical server that hosts only your virtual machine instances and no other tenant's instances.
Virtual Machine: A virtual machine instance is a virtual server that runs on a shared physical server with other tenants' instances.
Burstable: A burstable instance is a virtual machine instance that has a baseline utilization of either 12% or 50% of each CPU core and can burst above the baseline when needed.
NEW QUESTION # 39
Which TWO statements are TRUE about Private IP addresses in Oracle Cloud Infrastructure (OCI)?
- A. A private IP can have an optional public IP assigned to it if it resides in a public subnet.
- B. By default, the primary VNIC of an instance in a subnet has one primary private IP address and one secondary private IP address.
- C. By default, the primary VNIC of an instance in a subnet has one primary private IP address.
- D. Each VNIC can only have one private IP address.
Answer: A,C
Explanation:
By default, the primary VNIC of an instance in a subnet has one primary private IP address. A private IP can have an optional public IP assigned to it if it resides in a public subnet. The explanation is that a private IP address is an IPv4 address that is assigned to a VNIC and belongs to the CIDR block of the VCN or subnet. By default, the primary VNIC of an instance in a subnet has one primary private IP address, which is automatically assigned by OCI and cannot be changed. However, you can also assign secondary private IP addresses to a VNIC, either manually or automatically, up to a maximum of 31 per VNIC. A private IP address can have an optional public IP address assigned to it, which allows the instance to communicate with the internet. A public IP address can be either ephemeral or reserved, depending on whether you want to keep it after stopping or terminating the instance. A private IP address can only have a public IP address assigned to it if it resides in a public subnet, which means that the subnet's route table has a route rule that directs traffic to the internet gateway.
NEW QUESTION # 40
You are responsible for deploying an application on Oracle Cloud Infrastructure (OCI). The application is memory intensive and performs poorly if enough memory is not available. You have created an instance pool of Linux compute instances in OCI to host the application and defined Autoscaling Configuration for the instance pool.
What should you do to ensure that the instance pool autoscales to prevent poor application performance?
- A. Install OCI SDK on all compute instances and create a script that triggers the autoscaling event if there is high memory usage.
- B. Install the monitoring agent on all compute instances, which triggers the autoscaling group.
- C. Configure the autoscaling policy to monitor CPU usage and scale up the number of instances when it
- D. Configure the autoscaling policy to monitor memory usage and scale up the number of instances when it meets the threshold.
Answer: D
Explanation:
meets the threshold
