The other options are not suitable for this task, as they do not provide the functionality of OS Management service. Reference: [OS Management Service]
NEW QUESTION # 34
You have objects stored in an OCI Object Storage bucket that you want to share with a partner company. You decide to use pre-authenticated requests to grant access to the objects. Which statement is true about preauthenticated requests?
- A. Pre-authenticated requests can be used to delete buckets or objects.
- B. Deleting a pre-authenticated request does not revoke user access to the associated bucket or object.
- C. You need to provide your OCI credentials to the partner company.
- D. You cannot edit a pre-authenticated request.
Answer: D
Explanation:
You cannot edit a pre-authenticated request is a true statement about pre-authenticated requests. Pre-authenticated requests are URLs that allow users to access objects or buckets in OCI Object Storage without requiring additional authentication or authorization. Pre-authenticated requests can be created with an expiration date and time, and can be used for read or write operations. However, once created, pre-authenticated requests cannot be edited, but can only be deleted or extended. The other statements are false about pre-authenticated requests. Reference: [Pre-Authenticated Requests]

When creating an Oracle Cloud Infrastructure (OCI) Virtual Cloud Network (VCN) with the VCN wizard, which THREE gateways are created automatically?
- A. NAT Gateway
- B. Service Gateway
- C. Dynamic Routing Gateway
- D. Internet Gateway
- E. Bastion Host
- F. Storage Gateway
- G. Local Peering Gateway
Answer: A,B,D
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 # 36
Which THREE capabilities are available with the Oracle Cloud Infrastructure (OCI) DNS service?
- A. Creating and managing Identity Access Management (IAM) policies
- B. Creating and managing security lists
- C. Creating and managing records
- D. Creating and managing WAF rules
- E. Viewing all zones
- F. Creating and managing zones
Answer: C,E,F
Explanation:
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. References: [DNS Service], [Records], [Zones]
NEW QUESTION # 37
You want to distribute DNS traffic to different endpoints based on the location of the end user. Which Traffic Management Steering Policy would you use?
- A. IP Prefix
- B. Failover
- C. Geolocation
- D. Load Balancer
Answer: C
Explanation:
The explanation is that geolocation is a type of Traffic Management Steering Policy that allows you to distribute DNS traffic to different endpoints based on the location of the end user. Geolocation steering policies use geolocation data from third-party providers to map end user IP addresses to geographic regions. You can create rules that specify which endpoints to serve for each region or country, or use a default endpoint for unspecified regions.
NEW QUESTION # 38
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. You do not need to split the object into parts. Object Storage splits the object into parts and uploads all ofthe parts automatically.
- B. You do not have to commit the upload after you have uploaded all the object parts.
- C. While a multipart upload is still active, you can keep adding parts as long asthe total number is less than10,000.
- D. When you split the object into individual parts, each part can be as large as 50 GiB.
Answer: C,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 # 40
As a network architect you have been tasked with creating a fully redundant connection from your on-premises data center to your Virtual Cloud Network (VCN) in the us-ashburn-1 region.Which TWO options will accomplish this requirement?
- A. Configure one FastConnect virtual circuit to the us-ashburn-1 region and a Site-to-Site VPN to the usashburn-1 region.
- B. Configure two FastConnect virtual circuits to the us-ashburn-1 region and terminate them in diverse hardware on-premises.
- C. Configure one FastConnect virtual circuit to the us-ashburn-1 region and the second FastConnect virtual circuit to the us-phoenix-1 region.
- D. Configure a Site-to-Site VPN from a single on-premises CPE.
Answer: A,B
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 diverse hardware 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.
NEW QUESTION # 41
You are in the process of migrating several legacy applications from on-premises to Oracle Cloud Infrastructure (OCI). The current servers are already virtualized. However, you notice that the version of CentOS currentlyrunning does not align with any of the Oracle-provided compute images.How would you migrate your existing virtual server images to OCI?
- A. Export your current image in the VMDK format and copy to an Object Storage bucket. Import it as a custom image. Select native mode to ensure the best possible performance.
- B. Export your current image in the VDI format and copy to an Object Storagebucket. Import it as a customimage. Select native modeto ensure the best possible performance.
- C. Export your current image in the QED format and copy to an Object Storagebucket. Import it as a customimage. Select emulated modeto ensure compatibility with legacy drivers.
- D. Export your current image in the QCOW2 format and copy to an Object Storage bucket. Import it as a custom image. Select emulated mode to ensure compatibility with legacy drivers
Answer: D
Explanation:
Explanation
Export your current image in the QCOW2 format and copy to an Object Storage bucket. Import it as a custom image. Select emulated mode to ensure compatibility with legacy drivers. The explanation is that QCOW2 is one of the supported formats for importing custom images to OCI. Custom images are images that you can create from your own on-premises or cloud servers and use them to launch instances in OCI. To import a custom image, you need to export your current image in a supported format, copy it to an Object Storage bucket, and then import it as a custom image using the OCI console or API. When you import a custom image, you can choose between native mode or emulated mode. Native mode offers better performance but requires compatible drivers and firmware. Emulated mode offers better compatibility but lower performance.
NEW QUESTION # 42
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. User will be able to SSH to the VM from the Internet as SSH is open on the NSG.
- B. SSH traffic is not allowed in the security list nor on the NSG from the Internet.
- C. Internet traffic should be allowed only on the NSG.
- D. Public subnet does not have a route rule to the Internet Gateway.
Answer: B
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 # 43
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. Create a dynamic group with matching rules to specify which instances can make API calls against services.
- 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. Deploy the application and the SDK to all the instances that belong to the dynamic group.
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 # 44
What should be created before provisioning an Oracle Cloud Infrastructure (OCI) DB System?
- A. Compartment
- B. Compute Instance
- C. Bucket in Object Storage
- D. Virtual Cloud Network
Answer: D
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 # 45
Which statement is NOT correct regarding the Oracle Cloud Infrastructure (OI) File System snapshots?
- A. Even if nothing has changed within the file system since the last snapshot was taken, a new snapshot consumes more storage.
- B. Snapshots are accessible under the root directory of the file system at .snapshot/name.
- C. Before you can clone a file system, at least one snapshot must exist for the file system.
- D. Snapshots are a consistent, point-in-time view of your file systems.
Answer: A
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. Reference: [Snapshots and Storage Consumption]
NEW QUESTION # 46
You are using the Oracle Cloud Infrastructure (OCI) Vault service to create and manage Secrets. For your databasepassword, you have created a secret and rotated the secret one time. The secret versions are as follows:
Version Number | Status
-----------------------------------------
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. From the version 1 menu on the OCI console, select "Promote to Current".
- B. Deprecate version 2 (latest). Create new Secret version 3. Create soft link from version 3 to version 1.
- C. Create a new secret version 3 and set to Pending. Copy the content of version 1 into version 3.
- D. From the version 2 (latest) menu, select "Rollback" and select version 1 when given the option.
Answer: A
Explanation:
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 # 47
Which is NOT a valid Oracle Cloud Infrastructure (OCI) Virtual Cloud Network (VCN) approach?
- A. Ensure not all IP addresses are allocated at once within a VCN or subnet; instead reserve some IP addresses for future use.
- B. Use OCI tags to tag VCN resources so that all resources follow organizational tagging/naming conventions.
- C. Ensure VCN CIDR prefix overlaps with other VCNs in your tenancy or withyour organizations private IPnetwork ranges.
- D. Private subnets should ideally have individual route tables to control the flowof traffic within and outsideof VCN.
Answer: C
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.
