Question 92
Question
Which two statements are true about the Oracle Cloud Infrastructure Object Storage Service? (Choose two.)
A. It provides higher IOPS than Block Storage.
B. It can be directly attached or detached from a compute instance.
C. Data is stored redundantly only in a single AD.
D. Data is stored redundantly across multiple availability domains (ADs).
E. It provides strong consistency.
Answer
D. Data is stored redundantly across multiple availability domains (ADs).
E. It provides strong consistency.
Explanation
STRONG CONSISTENCY: When a read request is made, Object Storage always serves the most recent copy of the data that was written to the system.
DURABILITY: Object Storage is a regional service. Data is stored redundantly across multiple storage servers. Object Storage actively monitors data integrity using checksums and automatically detects and repairs corrupt data. Object Storage actively monitors and ensures data redundancy. If a redundancy loss is detected, Object Storage automatically creates more data copies. For more details about Object Storage durability, see the Oracle Cloud Infrastructure Object Storage FAQ.
CUSTOM METADATA: You can define your own extensive metadata as key-value pairs for any purpose. For example, you can create descriptive tags for objects, retrieve those tags, and sort through the data. You can assign custom metadata to objects and buckets using the Oracle Cloud Infrastructure CLI or SDK. See Software Development Kits and Command Line Interface for details.
ENCRYPTION: Object Storage employs 256-bit Advanced Encryption Standard (AES-256) to encrypt object data on the server. Each object is encrypted with its own key. Data encryption keys are encrypted with a master encryption key that is frequently rotated. Encryption is enabled by default and cannot be turned off.

Question 93
Question
Your company is moving an Internet-facing, 2-tier web application into Oracle Cloud Infrastructure.
The application must have a highly available architecture.
Which two design options would you consider? (Choose two.)
A. Configure a Dynamic Route Gateway in your VCN and make it highly available.
B. Configure a NAT instance in your Virtual Cloud Network (VCN). Create a route rule by using the private IP of the NAT instance as a route target for all the private subnets in your VCN.
C. Create an Internet Gateway and attach it to your VCN. Deploy public load balancer nodes into two Available Domains.
D. Place all web servers behind a public load balancer.
Answer
C. Create an Internet Gateway and attach it to your VCN. Deploy public load balancer nodes into two Available Domains.
D. Place all web servers behind a public load balancer.
Question 94
Question
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 preserving the boot volume. Create a new compute instance using a VM Dense IO shape using the boot volume preserved.
B. 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.
C. Create a backup of the boot volume. Create a new compute instance using a VM Dense IO shape and restore the backup.
D. 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.
Answer
A. Terminate the compute instance preserving the boot volume. Create a new compute instance using a VM Dense IO shape using the boot volume preserved.
B. 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.
Explanation
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.
Question 95
Question
Which statement is true about DB Systems?
A. Data Guard as a Service is offered between regions.
B. You cannot manage the database as sys/sysdba.
C. You have full control over the automatic backup schedule and retention periods.
D. You can manage Oracle database initialization parameters at a global level.
Answer
B. You cannot manage the database as sys/sysdba.
C. You have full control over the automatic backup schedule and retention periods.
Question 96
Question
What does Terraform use to create, manage, and manipulate infrastructure resources?
A. resources
B. provisioner
C. instances
D. provider
Answer
D. provider
Explanation
The Oracle Cloud Infrastructure provider is used to interact with the many resources supported by the Oracle Cloud Infrastructure. The provider needs to be configured with credentials for the Oracle Cloud Infrastructure account.
Question 97
Question
Which two statements are true about Database Cloud Service (DBCS)? (Choose two.)
A. Data Guard as a Service is offered among regions.
B. You have full control over backup schedule and retention.
C. You can manage Oracle parameters at a global system level.
D. You cannot manage the database as sys/sysdba.
Answer
B. You have full control over backup schedule and retention.
C. You can manage Oracle parameters at a global system level.
Explanation
Can I set up Data Guard across Availability Domains? Yes, you can set up Data Guard in the same or different Availability Domains in a region. However, Oracle recommends that you set up your Data Guard configuration across Availability Domains.
Can I set up Data Guard across Oracle Cloud Infrastructure regions? Yes, you can set up Data Guard across regions, but the Database Cloud Service Data Guard feature currently does not support it. You can manually set up Data Guard across regions by logging on to your host and using DGMGRL. You must enable an internet gateway on the primary and standby DB system VCN for Data Guard to transport logs across regions. Learn more about DGMGRL.
To configure a Data Guard system across regions or between on-premises and Oracle Cloud Infrastructure DB systems, you must access the database host directly and use the DGMGRL utility.

Question 98
Question
You have an application deployed in Oracle Cloud Infrastructure running only in the Phoenix region.
You were asked to create a disaster recovery (DR) plan that will protect against the loss of critical data. The DR site must be at least 500 miles from your primary site and data transfer between the two sites must not traverse the public Internet.
Which is the recommended disaster recovery plan?
A. Create a new virtual cloud network (VCN) in the Phoenix region and create a subnet in one availability domain (AD) that is not currently being used by your production systems. Establish VCN peering between the production and DR sites.
B. Create a DR environment in Ashburn. Associate a DRG with the VCN in each region and create a remote peering connection between the two VCNs.
C. Create a DR environment in Ashburn and provision a FastConnect virtual circuit using DRG between the regions.
D. Create a DR environment in Ashburn. Associate a dynamic routing gateway (DRG) with the VCN in each region and configure an IPsec VPN connection between the two regions.
Answer
B. Create a DR environment in Ashburn. Associate a DRG with the VCN in each region and create a remote peering connection between the two VCNs.
Explanation
Remote VCN peering is the process of connecting two VCNs in different regions (but the same tenancy). 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. Without peering, a given VCN would need an internet gateway and public IP addresses for the instances that need to communicate with another VCN in a different region.
At a high level, the Networking service components required for a remote peering include:
- Two VCNs with non-overlapping CIDRs, in different regions that support remote peering. The VCNs must be in the same tenancy.
- A dynamic routing gateway (DRG) attached to each VCN in the peering relationship. Your VCN already has a DRG if you’re using an IPSec VP Nor an Oracle Cloud Infrastructure FastConnectprivate virtual circuit.
A remote peering connection (RPC) on each DRG in the peering relationship.
A connection between those two RPCs.
Supporting route rules to enable traffic to flow over the connection, and only to and from select subnets in the respective VCNs (if desired).
Supporting security rules to control the types of traffic allowed to and from the instances in the subnets that need to communicate with the other VCN.
Question 99
Question
What is the maximum IP address size range that you can have in a Virtual Cloud Network?
A. /16
B. /26
C. /24
D. /8
Answer
A. /16
Explanation
When you create your VCN, you assign a contiguous IPv4 CIDR block of your choice. VCN sizes ranging from /16 (65,533 IP addresses) to /30 (1 IP address) are allowed. Example: 10.0.0.0/16, 192.168.0.0/24.
