質問 # 31
Your customer recently ordered for a 1-Gbps Fast Connect connection In ap-tokyo-1 region of Oracle Cloud Infrastructure (OCI). They will us this to one Virtual cloud Network (VCN) in their production (OC1) tenancy and VCN In their development OC1 tenancy As a Solution Architect, how should yon configure and architect the connectivity between on premises and VCNs In OCI?

A. Create a hub-VCN that uses Dynamic Routing Gateway (DRG) to communicate with on-premises network over FastConnect. Connect the hub-VCN to the production VCN spoke and with development VCN spoke, each peered via their respective local Peering Gateway (LPG)
B. Create a single private virtual circuit over FastConnect and attach fastConnect to either of the VCN's Dynamic Routing Gateway. Use Remote Peering to peer production and development VCNs.
C. Create two private virtual circuits on the FastConnect link. Create two Dynamic Routing Gateways, one for each VCNs. Attach the virtual circuits to the dynamic routing gateways.
D. You cannot achieve connectivity using single FastConnect link as the production and the development VCNs-are in separate tenancies. Request one more FastConnect connection.

正解：A

解説：
There's an advanced routing scenario called transit routing that enables communication between an onpremises network and multiple VCNs over a single Oracle Cloud Infrastructure FastConnect or IPSec VPN.
The VCNs must be in the same region and locally peered in a hub-and-spoke layout. As part of the scenario, the VCN that is acting as the hub has a route table associated with each LPG (typically route tables are associated with a VCN's subnets).

質問 # 34
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 default tag for each compartment, which ensure that appropriate tags are applied at resource creation
B. Create a policy to automatically tag a resource with the user name.
C. 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.
D. Create tag variables for each compartment to automatically tag a resource with the user name.
E. Create tag variables to automatically tag a resource with the user name.

正解：E

解説：
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} The type 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 you added 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 any other tag value. To create a tag variable, you must use a specific format.
${<variable>} 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 and with string values. Tag defaults let you specify tags to be applied automatically to all resources, at the time of creation, in a specific compartment. 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.

質問 # 35
You are part of a project team working in the development environment created in OCI. You have realized that the CIDR block specified for one of the subnet in a VCN is not correct and want to delete the subnet. While deleting you are getting an error indicating that there are still resources that you must delete first. The error includes the OCID of the VNIC that is in the subnet.
Which of the following action you will take to troubleshoot this issue?

A. Use OCI CLI to delete the subnet using --force option
B. Use OCI CLI to call "GetVnic" operation to find out the parent resource of the VNIC
C. Copy and Paste OCID of the VNIC in the search box of the OCI Console to find out the parent resource of the VNIC
D. Use OCI CLI to delete the VNIC first and then delete the subnet

正解：B

解説：
VCN, it must first be empty and have no related resources or attached gateways To delete a VCN's subnets, they must first be empty.
Note: When you create one of the preceding resources, you specify a VCN and subnet for it. The relevant service creates at least one VNIC in the subnet and attaches the VNIC to the resource. The service manages the VNICs on your behalf, so they are not readily apparent to you in the Console. The VNIC enables the resource to communicate with other resources over the network. Although this documentation commonly talks about the resource itself being in the subnet, it's actually the resource's attached VNIC.
If the subnet is not empty, you instead get an error indicating that there are still resources that you must delete first. The error includes the OCID of a VNIC that is in the subnet (there could be more, but the error returns only a single VNIC's OCID).
You can use the Oracle Cloud Infrastructure command line interface (CLI) or another SDK or client to call the GetVnic operation with the VNIC OCID. The response includes the VNIC's display name. Depending on the type of parent resource, the display name can indicate which parent resource the VNIC belongs to. You can then delete that parent resource, or you can contact your administrator to determine who owns the resource. When the VNIC's parent resource is deleted, the attached VNIC is also deleted from the subnet. If there are remaining VNICs in the subnet, repeat the process of determining and deleting each parent resource until the subnet is empty. Then you can delete the subnet.
For example, if you're using the CLI, use this command to get information about the VNIC.
oci network vnic get --vnic-id <VNIC_OCID

質問 # 42
You are designing the network infrastructure for two application servers: appserver-1 and appserver-2 running in two different subnets inside the same Virtual Cloud Network (VCN) Oracle Cloud Infrastructure (OCI). You have a requirement where your end users will access appserver-1 from the internet and appserver-2 from the on-premises network. The on-premises network is connected to your VCN over a FastConnect virtual circuit.
How should you design your routing configuration to meet these requirements?

A. Configure two routing tables: Route Table-1 that has a route to internet via the Internet gateway. Associate this route table to the subnet containing appserver-1. Route Table-2 that propagate specific routes for the on-premises network via the Dynamic Routing Gateway (DRG) Associate this route table to subnet containing appserver-2.
B. Configure a single routing table (Route Table-1) that has two set of rules. One that has route to internet via the internet Gateway and another that propagate specific routes for the on-premise network via the Dynamic Routing Gateway. Associate the routing table with all the VCN subnets.
C. Configure two routing table (Route table-1 Route Table-2) that have rule to route all traffic via the Dynamic Routing Gateway (DRG) Associate the two routing tables with all the VCN subnets.
D. Configure a single routing table (Routing Table-1) that has two set of rules: one that has route to internet via the Internet Gateway and another that propagates specific routes for the on-premises network via Dynamic Routing Gateway (DRG). Associate the routing table with the VCN.

正解：A

解説：
An internet gateway is an optional virtual router you can add to your VCN to enable direct connectivity to the internet. Resources that need to use the gateway for internet access must be in a public subnet and have public IP addresses. Each public subnet that needs to use the internet gateway must have a route table rule that specifies the gateway as the target. For traffic to flow between a subnet and an internet gateway, you must create a route rule accordingly in the subnet's route table (for example, destination CIDR = 0.0.0.0/0 and target = internet gateway).
Dynamic Routing Gateway (DRG) is A virtual edge router attached to your VCN. Necessary for private peering. The DRG is a single point of entry for private traffic coming in to your VCN,After creating the DRG, you must attach it to your VCN and add a route for the DRG in the VCN's route table to enable traffic flow.

質問 # 45
All three Data Guard Configuration are fully supported on Oracle Cloud infrastructure (OCI). You want to deploy a maximum availability architecture (MAA) for database workload.
Which option should you consider while designing your Data Guard configuration to ensure best RTO and PRO without causing any data loss?

A. Configure "Maximum Performance" mode In SYNC mode between two availability domains (same region) which provides, the highest level of data protection that is possible without affecting the performance of the primary database.
B. Configure ''Maximum Scalability" mode which provides the highest level of scalability without compromising the availability of the primary database.
C. Configure "Maximum Protection" mode which provides zero data loss If the primary database fails.
D. Configure ''Maximum Availability" mode in SYNC mode between two availability domains (same region), and use the Maximum Availability mode in SYNC mode between two regions.

正解：D

解説：
https://docs.cloud.oracle.com/en-us/iaas/Content/Resources/Assets/whitepapers/best-practices-for-dr-on-oci.pdf All three Data Guard configurations are fully supported on Oracle Cloud Infrastructure. However, because of a high risk of production outage, we don't recommend using the maximum protection mode for your Data Guard configuration.
We recommend using the maximum availability mode in SYNC mode between two availability domains (same region), and using the maximum availability mode in ASYNC mode between two regions. This architecture provides you the best RTO and RPO without causing any data loss. We recommend building this architecture in daisy-chain mode: the primary database ships redo logs to the first standby database in another availability domain in SYNC mode, and then the first standby database ships the redo logs to another region in ASYNC mode. This method ensures that your primary database is not doing the double work of shipping redo logs, which can cause performance impact on a production workload.

This configuration offers the following benefits:
No data loss within a region.
No overhead on the production database to maintain standbys in another region.
Option to configure lagging on the DR site if needed for business reasons.
Option to configure multiple standbys in different regions without any additional overhead on the production database. A typical use case is a CDN application Bottom of Form

A global media organization is working on a project which lets users upload their videos on their site. After upload is complete, the video should be automatically processed by an Al algorithm. The algorithm will try to recognize actions in the videos so that it can be used to show related advertisements in future. The development team wants to focus on writing Al code and don't want to worry about underlying infrastructure for high-availability, scalability, security and monitoring.
Which OCI services should you recommend for this project?

A. Use OCI Events service for triggering automatic processing of video, Oracle Container Engine for Kubernetes (OKE) and OCI Digital Assistant
B. Use Oracle Container Engine for Kubernetes (OKE) for deployment of Al Code, OCI Notifications and Object Storage
C. Use OCI Resource Manager to manage the underlying infrastructure, OCI Functions and OCI Events service.
D. Use Object Storage for storing videos, OCI Events service and OCI Functions

正解：D

解説：
Oracle Functions is a fully managed, multi-tenant, highly scalable, on-demand, Functions-as-a-Service platform. It is built on enterprise-grade Oracle Cloud Infrastructure and powered by the Fn Project open source engine. Use Oracle Functions (sometimes abbreviated to just Functions) when you want to focus on writing code to meet business needs.
The serverless and elastic architecture of Oracle Functions means there's no infrastructure administration or software administration for you to perform. You don't provision or maintain compute instances, and operating system software patches and upgrades are applied automatically. Oracle Functions simply ensures your app is highly-available, scalable, secure, and monitored. With Oracle Functions, you can write code in Java, Python, Node, Go, and Ruby (and for advanced use cases, bring your own Dockerfile, and Graal VM). You can then deploy your code, call it directly or trigger it in response to events, and get billed only for the resources consumed during the execution.
You can create automation based on state changes for your Oracle Cloud Infrastructure resources by using event types, rules, and actions. When the function is executing inside the container, the function can read from and write to other resources and services running in the same subnet (for example, Database as a Service). The function can also read from and write to other shared resources (for example, Object Storage), and other Oracle Cloud Services.

C. It is possible to spill this fileInto multiple parts using the APIs provided by Object Storage.
D. It is possible to split this file into multiple parts using rclone tool provided by Object Storage.
E. 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

正解：B、E

解説：
You can check on an active 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.
