質問 # 132
Which statement is true about OracleCloud Infrastructure FastConnect?

  • A. For private peering, FastConnect extends your existing infrastructure toa virtual cloud network
  • B. The FastConnect provider network offers only 1 Gbps port connection speed increments
  • C. For private peering, FastConnect extends your existing infrastructure to allow you to consume object storage from your on-premises data center
  • D. For public peering, a dynamic routing gateway must be configured and attached to the virtual cloud network (VCN)

正解：A

解説：
Explanation
With FastConnect, you can choose to use , or both.
Private peering: To extend your existing infrastructure into a virtual cloud network (VCN) in Oracle Cloud Infrastructure (for example, to implement a hybrid cloud, or a lift and shift scenario). Communication across the connection is with IPv4 private addresses (typically RFC 1918).
Public peering: To access public services in Oracle Cloud Infrastructure without using the internet. For example, Object Storage, the Oracle Cloud InfrastructureConsole and APIs, or public load balancers in your VCN. Communication across the connection is with IPv4 public IP addresses. Without FastConnect, the traffic destined for public IP addresses would be routed over the internet.

質問 # 137
You have hired a new employee to run reports from the Autonomous Data Warehouse (ADW) and are not confident in their SQL writing ability.
Into which consumer group will you assign this individual to minimize the impact of their code?

  • A. High
  • B. Medium
  • C. Low
  • D. Highest
  • E. Lowest

正解：C

解説：
Explanation
in ADW, The tnsnames.ora file provided with the credentials zip file contains three database service names identifiable as high, medium, and low. The predefined service names provide differentlevels of performance and concurrency for Autonomous Data Warehouse.
high: The High database service provides the highest level of resources to each SQL statement resulting in the highest performance, but supports the fewest number of concurrent SQL statements. Any SQL statement in this service can use all the CPU and IO resources in your database. The number of concurrent SQL statements that can be run in this service is 3, this number is independent of the number of OCPUs in your database.
medium: The Medium database service provides a lower level of resources to each SQL statement potentially resulting a lower level of performance, but supports more concurrent SQL statements. Any SQL statement in this service can use multiple CPU and IO resources in yourdatabase. The number of concurrent SQL statements that can be run in this service depends on the number of OCPUs in your database.
low: The Low database service provides the least level of resources to each SQL statement, but supports the most number of concurrent SQL statements. Any SQL statement in this service can use a single CPU and multiple IO resources in your database. The number of concurrent SQL statements that can be run in this service can be up to 300 times the number of OCPUs.
The predefinedservice names provide different levels of performance and concurrency for Autonomous DB Choose whichever database service offers the best balance of performance and concurrency.
Use the low database service name. to minimize the impact of their SQLs to by low consumer group

質問 # 141
You have created a new compartment called Production to host some production apps. You have also created users in your tenancy and added them to a Group called "production group". Your users are still unable to access the Production compartment. How can you resolve this situation?

  • A. Every compartment you create comes with a predefined set of policies, so no further action is needed
  • B. Write an IAM Policy for "production_group" granting it access to the production compartment
  • C. Your users get automatic access to all compartments, so no further action is needed
  • D. Write an IAM Policy for each specific user granting them access to the production compartment

正解：B

解説：
Explanation
When creating a compartment, you must provide a name for it (maximum 100 characters, including letters, numbers, periods, hyphens, and underscores) that is unique within its parent compartment. You must also provide a description, which is a non-unique, changeable description for the compartment, from 1through 400 characters.
After creating a compartment, you need to write at least one policy for it, otherwise no one can access it (except administrators or users who have permissions set at the tenancy level). When creating a compartment inside anothercompartment, the compartment inherits access permissions from compartments higher up its hierarchy.
When you create an access policy, you need to specify which compartment to attach it to. This controls who can later modify or delete the policy. Dependingon how you've designed your compartment hierarchy, you might attach it to the tenancy, a parent, or to the specific compartment itself.


質問 # 142
How can you provide users access to an existing compartment?

  • A. by granting users access to a compartment when the compartment is created
  • B. by adding users to a compartment. All users in the compartment will have access to the objects in the compartment.
  • C. by granting access directly to the user when the user is created
  • D. by adding users to a group and defining a policy to provide the group access to the compartment

正解：D

解説：
A policy is a document that specifies who can access which Oracle Cloud Infrastructure resources that your company has, and how. A policy simply allows a group to work in certain ways with specific types of resources in a particular compartment In general, here's the process an IAM administrator in your organization needs to follow:
Define users, groups, and one or more compartments to hold the cloud resources for your organization.
Create one or more policies, each written in the policy language.
Place users into the appropriate groups depending on the compartments and resources they need to work with.
Provide the users with the one-time passwords that they need in order to access the Console and work with the compartments. For more information,


質問 # 143
You are a network architect of an application running on Oracle Cloud Infrastructure (OCI). Your security team has informed you about a security patch that needs to be applied immediately to one of the backend web servers. What should you do to ensure that the OCI load balancer does not forward traffic to this backend server during maintenance?

  • A. Edit the security list associated with the subnet to avoid traffic connectivity to this backend serve
  • B. Drain all existing connections to this backend server and mark the backend web server offline
  • C. Create another OCI load balancer for the backend web servers, which are active and handling traffic
  • D. Stop the load balancer for maintenance and restart the load balancer after the maintenance is finished

正解：B

解説：
A load balancer improves resource utilization, facilitates scaling, and helps ensure high availability. You can configure multiple load balancing policies and application-specific health checks to ensure that the load balancer directs traffic only to healthy instances. The load balancer can reduce your maintenance window by draining traffic from an unhealthy application server before you remove it from service for maintenance.
The Load Balancing service considers a server marked drain available for existing persisted sessions. New requests that are not part of an existing persisted session are not sent to that server.
Edit Drain State: Opens a dialog box in which you can change the drain state.
If you set the server's drain status to true, the load balancer stops forwarding new TCP connections and new non-sticky HTTP requests to this backend server.
This setting allows an administrator to take the server out of rotation for maintenance purposes.
e. Edit Offline State: Opens a dialog box in which you can change the offline status.
If you set the server's offline status to true, the load balance forwards no ingress traffic to this backend server.


質問 # 144

質問 # 147
You are designing a two-tier web application in Oracle Cloud Infrastructure (OCI). Your clients want to access the web servers from anywhere, but want to prevent access to the database servers from the Internet.
Which is the recommended way to design the network architecture?

  • A. Create public subnets for web servers and private subnets for database servers in your VCN, and associate separate security lists and route tables for each subnet.
  • B. Create a single public subnet for your web servers and database servers, and associate only your web servers to internet gateway.
  • C. Create public subnets for web servers and private subnets for database servers in your virtual cloud network (VCN), and associate separate internet gateways for each subnet.
  • D. Create public subnets for web servers and associate a dynamic routing gateway with that subnet, and a private subnet for database servers with no association to dynamic gateway.

正解：A

解説：
When you create a subnet, by default it's considered public, which means instances in that subnet are allowed to have public IP addresses. Whoever launches the instance chooses whether it will have a public IP address. You can override that behavior when creating the subnet and request that it be private, which means instances launched in the subnet are prohibited from having public IP addresses. Network administrators can therefore ensure that instances in the subnet have no internet access, even if the VCN has a working internet gateway, and security rules and firewall rules allow the traffic.
There are two optional gateways (virtual routers) that you can add to your VCN depending on the type of internet access you need:
Internet gateway: For resources with public IP addresses that need to be reached from the internet (example: a web server) or need to initiate connections to the internet.
NAT gateway: For resources without public IP addresses that need to initiate connections to the internet (example: for software updates) but need to be protected from inbound connections from the internet.
Just having an internet gateway alone does not expose the instances in the VCN's subnets directly to the internet. The following requirements must also be met:
The internet gateway must be enabled (by default, the internet gateway is enabled upon creation).
The subnet must be public.
The subnet must have a route rule that directs traffic to the internet gateway.
The subnet must have security list rules that allow the traffic (and each instance's firewall must allow the traffic).
The instance must have a public IP address.

質問 # 149
You have an application running on Oracle Cloud Infrastructure. You identified that the read and write operations are slowing your application down enough to impair user access. The application is currently using a VM.Standard 1.2 compute without any block storage attached to it.
Which two options allow you to increase disk performance? (Choose two.)

  • A. Terminate the compute instance and create a backup of the boot volume. Create a new compute instance using a VM Dense IO shape and restore the backup.
  • B. Terminate the compute instance preserving the boot volume. Create a new compute instance using a VM Dense IO shape using the boot volume preserved.
  • C. Terminate the compute instance preserving the boot volume. Create a new compute instance using a VM Standard shape and attach a new block volume to host your application.
  • D. Create a backup of the boot volume. Create a new compute instance using a VM Dense IO shape and restore the backup.

正解：B、C

解説：
You can permanently terminate (delete) instances that you no longer need.By default, the instance's boot volume is deleted when you terminate the instance, however you can preserve the boot volume associated with the instance, so that you can attach it to a different instance as a data volume, or use it to launch a new instance.
You can use a boot volume backup to create an instance or you can attach it to another instance as a data volume. However before you can use a boot volume backup, you need to restore it to a boot volume.
