質問 # 96
Which two statements are true about Oracle Cloud Infrastructure (OCI) DB Systems Data Guard service?

  • A. Both DB systems must use the same VCN, and port 1521 must be open
  • B. Data guard implementation for Bare Metal shapes requires two DB Systems, one containing the primary database and one containing the standby database.
  • C. Data guard configuration on the OCI is limited to a virtual machine only
  • D. Data guard implementation requires two DB Systems, one running the primary database on a virtual machine and the standby database running on bare metal.

正解：A、B

解説：
Explanation
An Oracle Data Guard implementation requires two DB systems, one containing the primary database and one containing the standby database. When you enable Oracle Data Guard for a virtual machine DB system database, a new DB system with the standby database is created and associated with the primary database. For a bare metal DB system, the DB system with the database that you want to use asthe standby must already exist before you enable Oracle Data Guard.
Requirement details are as follows:
- Both DB systems must be in the same compartment.
- The DB systems must be the same shape type (for example, if the shape of the primary database isa virtual machine, then the shape of the standby database can be any other virtual machine shape).
- If your primary and standby databases are in different regions, then you must peer the virtual cloud networks (VCNs) for each database.
- Configure thesecurity list ingress and egress rules for the subnets of both DB systems in the Oracle Data Guard association to enable TCP traffic to move between the applicable ports. Ensure that the rules you create are stateful (the default).

質問 # 99
You deployed a web server in Oracle Cloud Infrastructure using an ephemeral public IP. After a few changes in your web server configuration, you rebooted the server and a new public IP was associated to your instance.
What should you doto prevent this from happening again?

  • A. Create a reserved public IP and associate it with the hosts file of your web server
  • B. Create a reservedpublic IP and associate it with the VNIC of your compute instance
  • C. Create a reserved public IP and associate it with the security list that your complete instance is using
  • D. Create a reserved public IP and associate it with the subnet of your compute instance

正解：B

解説：
Explanation
A public IP address is an IPv4 address that is reachable from the internet. If a resourcein your tenancy needs to be directly reachable from the internet, it must have a public IP address. Depending on the type of resource, there might be other requirements.
There are two types of public IPs:
Ephemeral: Think of it as temporary and existingfor the lifetime of the instance.
Reserved: Think of it as persistent and existing beyond the lifetime of the instance it's assigned to. You can unassign it and then reassign it to another instance whenever you like. Exception: reserved public IPs on public load balancers.
To create a new reservedpublic IP in your pool
Confirm you're viewing the region and compartment where you want to create the reserved public IP.
Open the navigation menu. Under Core Infrastructure, go to Networking and click Public IPs.
Click Create Reserved Public IP.
Enter the following:
Name: An optional friendly name for the reserved public IP. The name doesn't have to be unique, and you can change it later. Avoid entering confidential information.
Compartment: Leave as is.
Tags:Optionally, you can apply tags. If you have permissionsto create a resource, you also have permissions to apply free-form tags to that resource. To apply a defined tag, you must have permissions to use the tag namespace. For more information about tagging, see Resource Tags. If you are not sure if you should apply tags, skip this option (you can apply tags later) or ask your administrator.
Click Create Reserved Public IP.
To assign a reserved public IP to a private IP
Prerequisite: The private IP must not have an ephemeral or reserved public IP already assigned to it. If it does, first delete the ephemeral public IP, or unassign the reserved public IP.
Confirm you're viewing the compartment that contains the instance with the private IP you're interested in.
Open the navigation menu. Under Core Infrastructure, go to Compute and click Instances.
Click the instance to view its details.
Under Resources, click Attached VNICs.
The primary VNIC and any secondary VNICs attached to the instance are displayed.
Click the VNIC you're interested in.
Under Resources, click IP Addresses.
The VNIC's primary private IP and any secondary private IPs are displayed.
For the private IP you're interested in, click the Actions icon (three dots), and then click Edit.
In the Public IP Address section, for Public IP Type, select the radio button for Reserved Public IP.
Enter the following:
Compartment: The compartment that contains the reserved public IP you want to assign.
Reserved Public IP: The reserved public IP you want to assign. You have three choices:
Create a new reserved public IP. You may optionally provide a friendly name for it. The name doesn't have to be unique, and you can change it later. Avoid entering confidential information.
Assign a reserved public IP that is currently unassigned.
Move a reserved publicIP from another private IP.
Click Update.


質問 # 100
Your company decided to move a few applications to Oracle Cloud Infrastructure (OCI) in the US West (us-phoenix-1) region.
You need to design a cloud-based disaster recovery (DR) solution with a requirement to deploy the DR resources in the US East (us-ashburn-1) region to minimize network latency.
What is the recommended deployment?

  • A. Deploy production and DR applications in two separate VCNs in different availability domains (ADs) within the primary region, and then use a VCN remote peering connection for connectivity.
  • B. Deploy production and DR applications in two separate VCNs, each in different regions. Connect them using a VCN remote peering connection.
  • C. Deploy production and DR applications in the same VCN. Create production subnets in one AD, and DR subnets in another AD (assume a multi-AD region).
  • D. Deploy production and DR applications in two separate virtual cloud networks (VCNs), each in different regions, and then use VCN local peering gateways for connectivity.

正解：D

解説：
Remote VCN peering is the process of connecting two VCNs in different regions The peering allows the VCNs' resources to communicate using private IP addresses without routing the traffic over the internet or through your on-premises network.


質問 # 101
Which two statements are true regarding cloning a block volume?

  • A. You can clone block volumes across regions
  • B. You can skip block volume encryption when creating a clone
  • C. You can change the block volume size when creating a clone
  • D. You can change the block volume performance when creating a clone

正解：C、D

解説：
You can create a clone from a volume using the Block Volume service. Cloning enables you to make a copy of an existing block volume without needing to go through the backup and restore process.
A cloned volume is a point-in-time direct disk-to-disk deep copy of the source volume, so all the data that is in the source volume when the clone is created is copied to the clone volume.
You can only create a clone for a volume within the same region, availability domain and tenant. You can create a clone for a volume between compartments as long as you have the required access permissions for the operation.
during create a clone you can do the following
If you want to clone the block volume to a larger size volume, check Custom Block Volume Size (GB) and then specify the new size. You can only increase the size of the volume, you cannot decrease the size. If you clone the block volume to a larger size volume, you need to extend the volume's partition. See Extending the Partition for a Block Volume for more information.
If you want to change the elastic performance setting when cloning the volume, check Custom Block Volume Performance and select the elastic performance setting you want the volume clone to use. See Block Volume Elastic Performance for more information. You can also change the elastic performance setting after you have cloned the volume, see Block Volume Elastic Performance. If you leave Custom Block Volume Performance unchecked, the cloned volume will use the same elastic performance setting as the source volume.

質問 # 114
Which statement is true about the Oracle Cloud Infrastructure File Storage Service Snapshots?

  • A. You can restore the whole snapshot, but not the individual files
  • B. Snapshots are not incremental
  • C. It Is not possible to create snapshots from OCI console, but just the CLI
  • D. Snapshots are created under the root folder of file system, in a hidden directory named .snapshot

正解：D

解説：
Explanation
The File Storage service supports snapshotsfor data protection of your file system. Snapshots are a consistent, point-in-time view of your file systems. Snapshots are copy-on-write, and scoped to the entire file system. The File Storage service encrypts all file system and snapshot data at rest. You can take as many snapshots as you need.
Data usage is metered against differentiated snapshot data. If nothing has changed within the file system since the last snapshot was taken, the new snapshot does not consume more storage Snapshots are accessibleunder the root directory of the file system at .snapshot/name. For data protection, you can use a tool that supports NFSv3 to copy your data to a different availability domain, region, file system, object storage, or remote location.


質問 # 115
What happens when you run terraform plan?

  • A. It deletes all existing resources and re-creates them.
  • B. It shows adependency graph.
  • C. It shows the operator the course of action that would be taken if a change is applied.
  • D. It configures, reconfigures, and instantiates resources and their dependencies.

正解：C

解説：
Explanation
References:
The terraform plan command is used to create an execution plan. Terraform performs a refresh, unless explicitly disabled, and then determines what actions are necessary to achieve the desired state specified in theconfiguration files.
This command is a convenient way to check whether the execution plan for a set of changes matches your expectations without making any changes to real resources or to the state. For example, terraform plan might be run before committing a change to version control, to create confidence that it will behave as expected.
