You are tasked to quickly identify the details of allusers who were active in the last six hours along with any REST API calls that were executed.
Which OCI service would you use?

• A. Logging
• B. Audit
• C. Notifications
• D. Notifications
• E. Service Connectors

Answer: B

Explanation:
Explanation
Audit is the OCI service that would help identify the details of all users who were active in the last six hours along with any REST API calls that were executed. Audit is a service that records all API calls and other actions taken by or on behalf of users in OCI. It can be used to track user activity, monitor compliance, and troubleshoot issues. The other options are not suitable for this task. References: [Audit]

NEW QUESTION # 31
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. Modify the security list associated with the subnet where the mount target resides.
• B. 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.
• C. Create an NFS export option that allows READ_ONLY access where the source is the CIDR range of the DBSystem subnet.
• D. Change the ingress rules corresponding to the DB System subnet to be stateful.
• E. 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.

Answer: C

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 # 32
Which THREE capabilities are available with the Oracle Cloud Infrastructure (OCI) DNS service?

• A. Creating and managing WAF rules
• B. Creating and managing zones
• C. Creating and managing security lists
• D. Creating and managing Identity Access Management (IAM) policies
• E. Creating and managing records
• F. Viewing all zones

Answer: B,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 # 33
When creating an Oracle Cloud Infrastructure (OCI) Virtual Cloud Network (VCN) with the VCN wizard, which THREE gateways are created automatically?

• A. Dynamic Routing Gateway
• B. Bastion Host
• C. Local Peering Gateway
• D. Storage Gateway
• E. NAT Gateway
• F. Service Gateway
• G. Internet Gateway

Answer: E,F,G

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 # 34
You have a block volume created in the US West (Phoenix) region. You enabled Cross Region Replication for the volume and selected US West (San Jose) as the destination region. Now, you would like to create a new volume from the volume replica in the US West (San Jose) region.
What should you do?

• A. Trigger the replica.
• B. Activate the replica.
• C. Initiate the replica.
• D. No action required. By default, the replica is available as a block volume.

Answer: B

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.

Cloud Guard monitors user activity and resource configurations using data collectors and detectors, evaluates them against predefined or custom rules, generates problems and recommendations based on severity levels, and executes responders to fix the issues automatically or manually.

NEW QUESTION # 38
You are using a custom application with third-party APIs to manage the application and data hosted in an Oracle Cloud Infrastructure (OCI) tenancy. Although your third-party APIs do not support OCI's signature-based authentication, you want them to communicate with OCI resources. Which authentication option should you use to ensure this?

• A. OCI Username and Password
• B. Auth Tokens
• C. API Signing Key
• D. SSH Key Pair with 2048-bit algorithm

Answer: B

Explanation:
Auth Tokens is the authentication option that you should use to ensure that your custom application with third-party APIs can communicate with OCI resources. Auth Tokens are tokens that can be used as an alternative to passwords when making API calls to OCI services. Auth Tokens can be generated and revoked by users in the OCI Console or CLI, and can be used with any API client that supports basic authentication. The other options are not suitable for this scenario, as they either require OCI's signature-based authentication or are not applicable for API calls. Reference: [Auth Tokens]

NEW QUESTION # 39
Which Oracle Cloud Infrastructure (OCI) Identity and Access Management (IAM) policy is invalid?

• A. Allow group A-Admins to manage all-resources in compartment Project-A
• B. Allow group A-Developers to create volumes in compartment Project-A
• C. Allow dynamic-group FrontEnd to manage instance-family in compartment Project-A
• D. Allow any-user to inspect users in tenancy

Answer: B

Explanation:
Allow group A-Developers to create volumes in compartment Project-A is an invalid IAM policy. This is because create is not a valid verb for volumes. The correct verb for creating volumes is attach. The other options are valid IAM policies that use correct verbs and syntax. Reference: [IAM Policies], [Verbs]

NEW QUESTION # 40
You have a high-demand web application running on Oracle Cloud Infrastructure (OCI). Your tenancy administrator has set up a schedule-based autoscaling policy on instance pool withan initial size of 5 instancesfor the application.
Policy 1:
Target pool size:10 instances
Execution time:8:30 a.m. on every Monday through Friday, in every month, in every year Cron expression:0 30 8 ? * MON-FRI * Which statement accurately explains the goal of this policy?

• A. Goal: A recurring monthly schedule. On all days of the month, set the initial pool size to 5 instances. At
  8.30 a.m., on every day of the month, scale out to 10 instances.
• B. Goal: A recurring daily schedule. On weekday mornings at 8.30 a.m., scale out to 10 instances.
• C. Goal: A recurring weekly schedule. On all days of the week at 8.30 a.m., scale out the pool to 10 instancesfrom the initial size of 5
• D. Goal: A one-time schedule with only one scaling out event. At 8:30 a.m., on December 31, 2021, scale theinstance pool to 10 instances from 5.

Answer: B

Explanation:
Explanation
The explanation is that a schedule-based autoscaling policy allows you to adjust the size of your instance pool based on a cron expression that specifies the date and time of the scaling action. The cron expression consists of six fields: seconds, minutes, hours, day of month, month, and day of week. In this case, the cron expression is 0 30 8 ? * MON-FRI *, which means that the scaling action will occur at 8:30 a.m. on every Monday through Friday, regardless of the day of month or month. Therefore, the goal of this policy is to scale out the instance pool to 10 instances on weekday mornings at 8:30 a.m.

NEW QUESTION # 43
Which statement is TRUE about delegating an existing domain to the OracleCloud Infrastructure (OCI) DNS service?

• A. All domains can be retrieved to OCI DNS via DYN.
• B. Domains can be delegated to OCI DNS from the Domain Registrar's self-service portal.
• C. Domains can be self-delegated to OCI DNS from its own service portal.
• D. Domains can be delegated to OCI DNS from the OCI Marketplace.
• E. Domains can be delegated to OCI DNS via FastConnect partners.

Answer: B

Explanation:
Explanation
Domains can be delegated to OCI DNS from the Domain Registrar's self-service portal. The explanation is that delegating a domain to OCI DNS means that you are transferring the authority to resolve DNS queries for your domain from your current DNS provider to OCI DNS. To delegate a domain to OCI DNS, you need to create a zone in OCI DNS that matches your domain name and add any records that you want to serve from OCI DNS. Then, you need to update the name servers for your domain at your Domain Registrar's self-service portal with the name servers provided by OCI DNS. This will point your domain to OCI DNS and allow it to resolve DNS queries for your domain.

NEW QUESTION # 44
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. The secret for the key was not created beforehand
• B. The Object Storage bucket policy lacks the necessary Access Control List (ACL).
• C. There is no Identity and Access Management (IAM) policy that allows the Object Storage service to use thekey.
• D. The storage administrator forgot to select "Encrypt using Oracle managed keys" while creating the bucket.

Answer: C

Explanation:
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.

NEW QUESTION # 45
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. SSH traffic is not allowed in the security list nor on the NSG from the Internet.
• B. User will be able to SSH to the VM from the Internet as SSH is open on the NSG.
• C. Internet traffic should be allowed only on the NSG.
• D. Public subnet does not have a route rule to the Internet Gateway.

Answer: A

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 # 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. Private subnets should ideally have individual route tables to control the flowof traffic within and outsideof VCN.
• C. Use OCI tags to tag VCN resources so that all resources follow organizational tagging/naming conventions.
• D. Ensure VCN CIDR prefix overlaps with other VCNs in your tenancy or withyour organizations private IPnetwork ranges.

Answer: D

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 # 48
You want to distribute DNS traffic to different endpoints based on the locationof the end user. Which TrafficManagement Steering Policy would you use?

• A. IP Prefix
• B. Failover
• C. Geolocation
• D. Load Balancer

Answer: C

Explanation:
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 # 49
You are responsible for creating and maintaining an enterprise application that consists of multiple storage volumes across multiple compute instances in Oracle Cloud Infrastructure (OCI).
The storage volumes include boot volumes and block volumes for your data storage. You need to create a backup for the boot volumes that will be done daily and a backup for the block volumes that will be done every six hours.
How can you meet this requirement?

• A. Create clones of all boot volumes and block volumes one at a time.
• B. Group multiple storage volumes in a volume group and create volume group backups.
• C. Group the boot volumes into a volume group and create a custom backup policy. Group the block volumes and create a custom backup policy.
• D. Create on-demand full backups of block volumes, and create custom images from the boot volumes. Use a function to run at a specific time to start the backup process.

Answer: C

Explanation:
Group the boot volumes into a volume group and create a custom backup policy. Group the block volumes and create a custom backup policy. The explanation is that volume groups are logical collections of block volumes and boot volumes that can be backed up together as a consistent point-in-time snapshot. You can create a custom backup policy for each volume group and specify the frequency and retention period of the backups. This way, you can meet different backup requirements for different types of volumes.
