Question 261
Question
Which is a customer’s responsibility on an Oracle Cloud Infrastructure database?
A. patching the database and OS
B. creating the first default database on the DBCS server
C. creating an ASM diskgroup for data file or temp file storage
D. installing the operating system (OS), Grid Infrastructure, and database software
Answer
A. patching the database and OS
Explanation
On autonomous there’s no patching needed. But on the regular DB Cloud services you need to patch the DB and the OS. During the creation on the OCDB the first DB is created automatically
Oracle automatically takes care of Operating system Installation/Configuration, Grid Infrastructure, ASM diskgroup Creation/Configuration, and database software Installation and first database on the DB System. that’s all when Creating DB Systems. and then the customer responsible to apply the patches to the database and OS
Question 262
Question
As the Cloud Architect for your company, you have been tasked with designing a high-performance (HPC) cluster in Oracle Cloud Infrastructure (OCI). The following requirements have been defined:
- The cluster must be a minimum of three nodes, but may increase to six nodes when demand requires.
- The cluster must be resilient to any potential infrastructure failures.
- To minimize latency, all nodes must be deployed within the same availability domain (AD).
- Adding or replacing nodes within the cluster should take no more than 30 minutes.
Which two steps should be performed to satisfy these requirements in OCI? (Choose two.)
A. Deploy the cluster in a single AD with a shared file system that leverages the file storage service (FSS). Deploy a standby cluster in another AD and configure it to use the same shared file system.
B. Deploy the cluster in a single AD. Place each of the nodes in one of the three different fault domains in that AD.
C. Create a backup of your HPC node compute instance boot volume. Launch new compute instances directly from the backup reduce provisioning time.
D. Create a custom image of your HPC node compute instance. Launch new compute instances using this image to reduce provisioning time.
E. Deploy the cluster in a single AD. Place each of the nodes in a different virtual cloud network (VCN) subnet.
Answer
B. Deploy the cluster in a single AD. Place each of the nodes in one of the three different fault domains in that AD.
D. Create a custom image of your HPC node compute instance. Launch new compute instances using this image to reduce provisioning time.
Explanation
A fault domain is a grouping of hardware and infrastructure within an availability domain. Each availability domain contains three fault domains. Fault domains provide anti-affinity: they let you distribute your instances so that the instances are not on the same physical hardware within a single availability domain. A hardware failure or Compute hardware maintenance event that affects one fault domain does not affect instances in other fault domains. In addition, the physical hardware in a fault domain has independent and redundant power supplies, which prevents a failure in the power supply hardware within one fault domain from affecting other fault domains.
To control the placement of your compute instances, bare metal DB system instances, or virtual machine DB system instances, you can optionally specify the fault domain for a new instance or instance pool at launch time. If you don’t specify the fault domain, the system selects one for you. Oracle Cloud Infrastructure makes a best-effort anti-affinity placement across different fault domains, while optimizing for available capacity in the availability domain. To change the fault domain for an instance, terminate it and launch a new instance in the preferred fault domain.
Use fault domains to do the following things:
- Protect against unexpected hardware failures or power supply failures.
- Protect against planned outages because of Compute hardware maintenance.
Question 263
Question
What is true about data guard set up with fast-start failover (FSFO) in Oracle Cloud Infrastructure (OCI)?
A. The best practice for high availability and durability is to run the primary, standby, and observer in separate availability domains (ADs).
B. When you configure data guard using OCI console, the default mode is set to maxprotection.
C. You cannot create the standby DB system in a different AD from the primary DB system.
D. You cannot use database command-line interface (CLI) to set up data guard with FSFO.
Answer
A. The best practice for high availability and durability is to run the primary, standby, and observer in separate availability domains (ADs).
Explanation
The best practice for high availability and durability is to run the primary, standby, and observer in separate availability domains. The observer determines whether or not to failover to a specific target standby database

Question 264
Question
A company currently uses Microsoft Active Directory as its identity provider. The company recently subscribed to Oracle Cloud Infrastructure (OCI) to leverage the cloud platform for test and development. As the administrator, you configured the OCI tenancy to be federated with Microsoft Active Directory. Now you need to give access to developers so that they can start creating resources in their OCI accounts.
Which step will you perform to make sure you are not duplicating user creation inside of OCI tenancy?
A. Create a group for developers on OCI and map the group to a similar group in Microsoft Active Directory during the federation process.
B. Create a new user account in OCI for each user, and then create policies to provide access to developers.
C. Create a group for developers on OCI, export all the developers from Microsoft Active Directory, and then import them into the Identity and Access Management (IAM) group.
D. Create a single user account in OCI, and then create policies to provide access to developers to this single account.
Answer
A. Create a group for developers on OCI and map the group to a similar group in Microsoft Active Directory during the federation process.
Explanation
When working with your IdP, your administrator defines groups and assigns each user to one or more groups according to the type of access the user needs. Oracle Cloud Infrastructure also uses the concept of groups (in conjunction with IAM policies) to define the type of access a user has. As part of setting up the relationship with the IdP, your administrator can map each IdP group to a similarly defined IAM group, so that your company can re-use the IdP group definitions when authorizing user access to Oracle Cloud Infrastructure resources.
Question 265
Question
Which two statements are true about Autonomous Data Warehouse (ADW) backup?
A. You can perform manual backups to OCI object storage in addition to automated backups available on ADW
B. You can backup ADW database only to a standard bucket type in OCI object storage
C. Oracle Cloud Infrastructure (OCI) recommends backing up ADW databases manually to on-premises storage devices
D. You must backup ADW database to object storage bucket named ADW_backup
Answer
A. You can perform manual backups to OCI object storage in addition to automated backups available on ADW
B. You can backup ADW database only to a standard bucket type in OCI object storage
Explanation
Autonomous Database automatically backs up your database for you. In addition to automatic backups Autonomous Database also allows you take manual backups to your Oracle Cloud Infrastructure Object Storage. for example if you want to take a backup before a major change to make restore and recovery faster.
Also, Manual backups are only supported with buckets created in the standard storage tier
if you provision an Autonomous Data Warehouse instance named ADWC1, the bucket name should be backup_adwc1 (the bucket name is lowercase)
Question 266
Question
You are in the process of setting up a highly available student registration website on Oracle Cloud Infrastructure (OCI). You use a load balancer and a database service on OCI. You launch two compute instances each in a different subnet and add them to the back end set of a public load balancer. The load balancer is configured correctly and working. You then deploy the student registration application on these two compute instances. The application can communicate with the database service. However, when you type the URL of this student registration application in your browser, no web page appears. What could be the cause?
A. The security lists of the subnets on which the two instances are located do not have “allow” rules for port 80 and 443.
B. The load balancer performed a health check on the application and found that compute instances were not in a healthy state and terminated the instances.
C. The Dynamic Routing Gateway is preventing the client traffic from your data center network from reaching the public IP of the load balancer.
D. The client requested HTTPS access to the application and the load balancer service does not support end-to-end SSL from the client to the listener to the back-end set.
Answer
A. The security lists of the subnets on which the two instances are located do not have “allow” rulesfor port 80 and 443.

Question 268
Question
Which type of IP address may be unassigned and reassigned between compute instances?
A. Public IP
B. Private IP
C. IPv6 IP
D. Floating IP
Answer
D. Floating IP
