NEW QUESTION # 30
When creating an Oracle Cloud Infrastructure (OCI) Virtual Cloud Network (VCN) with the VCN wizard, which THREE gateways are created automatically?
- A. Storage Gateway
- B. Local Peering Gateway
- C. NAT Gateway
- D. Internet Gateway
- E. Dynamic Routing Gateway
- F. Service Gateway
- G. Bastion Host
Answer: C,D,F
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. Reference: [VCN Wizard], [Gateways]
NEW QUESTION # 31
Which is NOT a valid option for an Oracle Cloud Infrastructure (OCI) compute shape?
- A. Dedicated Virtual Machine Host
- B. Bare Metal
- C. Exadata Virtual Machine
- D. Virtual Machine
Answer: C
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 # 32
Which TWO statements are NOTcorrect regarding the Oracle Cloud Infrastructure (OCI) burstable instances?
- A. Baseline utilization is a fraction of each CPU core, either 25% or 75%.
- B. Burstable instances cost less than regular instances with the same total OCPU count.
- C. If the instance's average CPU utilization over the past 24 hours is below thebaseline, the system allows itto burst above the baseline.
- D. Burstable instances are designed for scenarios where an instance is not typically idle and has high CPUutilization.
- E. Burstable instances are charged according to the baseline OCPU.
Answer: A,D
Explanation:
Explanation
The explanation is that burstable instances are VM instances that have a baseline utilization of either 12% or 50% of each CPU core, not 25% or 75%. Burstable instances are designed for scenarios where an instance is typically idle or has low CPU utilization but occasionally needs to burst above the baseline to handle spikes in demand. Burstable instances cost less than regular instances with the same total OCPU count but charge extra for bursting above the baseline OCPU.
NEW QUESTION # 33
You are backing up your on-premises data to the Oracle Cloud Infrastructure (OCI) Object Storage Service.
Your requirements are:
1. Backups need to be retained for at least full 31 days.
2. Data should be accessible immediately if and when needed after the backup.
Which OCI Object Storage tier is suitable for storing the backup to minimize cost?
- A. Standard tier
- B. Infrequent Access tier
- C. Archive tier
- D. Auto-Tiering tier
Answer: B
Explanation:
The explanation is that the Infrequent Access tier is suitable for storing data that is accessed less frequently but requires immediate access when needed. The Infrequent Access tier has lower storage costs than the Standard tier, but higher retrieval costs. The Infrequent Access tier also has a minimum storage duration of 30 days, which means that you will be charged for at least 30 days of storage even if you delete or move the data before that period.
NEW QUESTION # 34
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.
- C. By default, the primary VNIC of an instance in a subnet has one primary private IP address and one secondary private IP address.
- D. Each VNIC can only have one private IP address.
Answer: A,B
Explanation:
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 # 35
You created a virtual cloud network (VCN) with three private subnets. Two of the subnets contain applicationservers and the third subnet contains a DB System. The application requires a shared file system, therefore youhave provisioned one using the file storage service (FSS).
You have also created the corresponding mount target in one of the application subnets. The VCN security listsare properly configured so that the application servers can access FSS. The securityteam changed the settings forthe DB System to have read-only access to the file system. However when they testit, they are unable to accessFSS.
How would you allow access to FSS?
- A. Create an instance principal for the DB System. Write an Identity andAccess Management (IAM) policythat allows the instance principal read-only access to the file storage service.
- B. Modify the security list associated with the subnet where the mount target resides.
- C. Change the ingress rules corresponding to the DB System subnet to be stateful.
- D. Create an NFS export option that allows READ_ONLY access where the source is the CIDR range of the DBSystem subnet.
- E. Modify the security list associated with the subnet where the mount target resides. Change the ingressrules corresponding to the DB System subnet to be stateless.
Answer: D
Explanation:
Explanation
Creating an NFS export option that allows READ_ONLY access where the source is the CIDR range of the DB System subnet is the correct answer. This is because NFS export options are used to control the level of access that clients have to file systems. By creating an NFS export option with READ_ONLY access for the DB System subnet, you can allow the DB System to read data from the file system, but not write or modify it.
The other options are not correct, as they do not address the requirement of read-only access for the DB System. References: [NFS Export Options]
NEW QUESTION # 36
Which TWO are key benefits of setting up Site-to-Site VPN on Oracle Cloud Infrastructure (OCI)?
- A. When setting up Site-to-Site VPN, customers can expect bandwidth above 2 Gbps.
- B. When setting up Site-to-Site VPN, it creates a private connection that provides consistent network experience.
- C. When setting up Site-to-Site VPN, customers can configure it to use static or dynamic routing (BGP).
- D. When setting up Site-to-Site VPN, OCI provisions redundant VPN tunnels.
Answer: C,D
Explanation:
Explanation
When setting up Site-to-Site VPN, customers can configure it to use static or dynamic routing (BGP). When setting up Site-to-Site VPN, OCI provisions redundant VPN tunnels. The explanation is that Site-to-Site VPN is a secure and encrypted connection between your on-premises network and your Virtual Cloud Network (VCN) in OCI over the public internet. When setting up Site-to-Site VPN, you can choose to use static routing or dynamic routing (Border Gateway Protocol or BGP) to exchange routes between your network and OCI.
OCI also provisions two redundant VPN tunnels for each Site-to-Site VPN connection to provide high availability and failover.
NEW QUESTION # 37
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.
- C. By default, the primary VNIC of an instance in a subnet has one primary private IP address and one secondary private IP address.
- D. Each VNIC can only have one private IP address.
Answer: A,B
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 # 38
Which of the following statements is true about cloning a volume in the Oracle Cloud Infrastructure (OCI) Block Volume service?
- A. Creating a clone takes longer than creating a backup of a volume.
- B. You need to detach a volume before cloning it.
- C. You can clone a volume to another region.
- D. You can change the block volume size when cloning a volume.
Answer: D
Explanation:
You can change the block volume size when cloning a volume. The explanation is that cloning a volume is a way of creating an exact copy of an existing volume without creating a backup first. Cloning a volume is faster and cheaper than creating a backup and restoring it to a new volume. When you clone a volume, you can change the block volume size, performance, encryption settings, and tags of the new volume. You do not need to detach a volume before cloning it, as cloning does not affect the source volume or its attachments. You cannot clone a volume to another region, as cloning only works within the same region and availability domain. Creating a clone usually takes less time than creating a backup of a volume, as cloning does not involve transferring data to Object Storage.
NEW QUESTION # 39
Which THREE capabilities are available with the Oracle Cloud Infrastructure (OCI) DNS service?
- A. Creating and managing records
- B. Viewing all zones
- C. Creating and managing security lists
- D. Creating and managing zones
- E. Creating and managing Identity Access Management (IAM) policies
- F. Creating and managing WAF rules
Answer: A,B,D
Explanation:
Creating and managing records, creating and managing zones, and viewing all zones are three capabilities that are available with the OCI DNS service. Records are data elements that map domain names to IP addresses or other information. Zones are collections of records that correspond to a domain name or a subdomain name. The OCI DNS service allows users to create and manage records and zones for their domains or subdomains, as well as view all zones in their tenancy. The other options are not capabilities of the OCI DNS service, but of other OCI services such as WAF, IAM, and Networking. Reference: [DNS Service], [Records], [Zones]
NEW QUESTION # 40
You are using the Oracle Cloud Infrastructure (OCI) Vault service to create and manage Secrets. For your database password, you have created a secret and rotated the secret one time. The secret versions are as follows:
-----------------------------------------
2 (latest) | Current
1 | Previous
You later realize that you have made a mistake in updating the secret content for version 2 and want to rollback to version 1.
What should you do to rollback to version 1?
- A. Deprecate version 2 (latest). Create new Secret version 3. Create soft link from version 3 to version 1.
- B. Create a new secret version 3 and set to Pending. Copy the content of version 1 into version 3.
- C. From the version 1 menu on the OCI console, select "Promote to Current".
- D. From the version 2 (latest) menu, select "Rollback" and select version 1 when given the option.
Answer: C
Explanation:
From the version 1 menu on the OCI console, select "Promote to Current". The explanation is that when you promote a secret version to current, it becomes the latest version of the secret and is used by default when you access the secret. This way, you can rollback to a previous version of the secret without creating a new version.
NEW QUESTION # 41
Your DevOps team needs to interconnect the on-premises network to the Oracle Cloud Infrastructure (OCI) resources, such as a managed database that resides in a private subnet. They indicate that they have a low budget and their bandwidth requirements are minimal, so you decide that a site-to-site VPN is the best option.
They provide you with their router public IP address. You need to create an object in OCI that represents this router. Which object would you create?
- A. Customer Premises Equipment (CPE)
- B. Virtual Network Interface Card (vNIC)
- C. IPSec Tunnel
- D. Dynamic Routing Gateway (DRG)
- E. Internet Gateway
- F. Bastion Host
Answer: A
Explanation:
Customer Premises Equipment (CPE). The explanation is that CPE is an object in OCI that represents your on-premises router or VPN device that connects to your VCN via a site-to-site VPN. A site-to-site VPN is a secure and encrypted connection between your on-premises network and your VCN over the public internet. To set up a site-to-site VPN, you need to create a CPE object with your router's public IP address and other information, such as vendor and platform. You also need to create a Dynamic Routing Gateway (DRG) object in your VCN and attach it to your VCN. Then, you need to create an IPSec connection between your CPE and DRG, which will create two redundant VPN tunnels for high availability.
NEW QUESTION # 42
Which statement is NOT correct regarding the Oracle Cloud Infrastructure (OI) File System snapshots?
- A. Snapshots are accessible under the root directory of the file system at .snapshot/name.
- B. Before you can clone a file system, at least one snapshot must exist for the file system.
- C. Even if nothing has changed within the file system since the last snapshot was taken, a new snapshot consumes more storage.
- D. Snapshots are a consistent, point-in-time view of your file systems.
Answer: C
Explanation:
Explanation
Even if nothing has changed within the file system since the last snapshot was taken, a new snapshot does not consume more storage. This is because snapshots are incremental and only store the changes made to the file system since the previous snapshot. The other statements are correct regarding the OCI File System snapshots.
References: [Snapshots and Storage Consumption]

This means that you can use OCI FastConnect to establish a private and dedicated connection between OCI and Azure in London, with high bandwidth and predictable performance. This connection can also enable you to leverage OCI Autonomous Data Warehouse ML capabilities from Azure resources, as you can access OCI services across regions using private IP addresses. The interconnect location can be provisioned quickly using the OCI and Azure consoles or APIs.
NEW QUESTION # 45
What should be created before provisioning an Oracle Cloud Infrastructure (OCI) DB System?
- A. Bucket in Object Storage
- B. Compartment
- C. Compute Instance
- D. Virtual Cloud Network
Answer: D
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 # 46
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 within14 to 16 days and sends you anotification.
What would happen if you choose not to proactively reboot the instance beforethe scheduled maintenance duedate?
- A. The instance will get terminated.
- B. You will receive another notification to reboot within the next 7 days.
- C. You will receive another notification to reboot within the next 14 days.
- D. The instance is either reboot-migrated or rebuilt in place for you.
Answer: D
Explanation:
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. References:
