Oracle Cloud 1z0-1072 Practice Test 1-13
QUESTION 1
Your application consists of three Oracle Cloud Infrastructure compute instances running behind a public load balancer.
You have configured the load balancer to perform health checks on these instances, but one of the three instances fails
to pass the configured health check. Which of the following action will the load balancer perform?
A. Stop sending traffic to the instance that failed health check
B. B. Terminate the instance that failed health check
C. C. Stop the instances that failed health check
D. D. Remove the instance that failed the health check from the backend set
Correct Answer: A
health check A test to confirm the availability of backend servers. A health check can be a request or a connection
attempt. Based on a time interval you specify, the load balancer applies the health check policy to continuously monitor
backend servers. If a server fails the health check, the load balancer takes the server temporarily out of rotation. If the
server subsequently passes the health check, the load balancer returns it to the rotation.
You configure your health check policy when you create a backend set. You can configure TCP-level or HTTP-level
health checks for your backend servers.
–
TCP-level health checks attempt to make a TCP connection with the backend servers and validate the response based
on the connection status.
–
HTTP-level health checks send requests to the backend servers at a specific URI and validate the response based on
the status code or entity data (body) returned. The service provides application-specific health check capabilities to help
you increase availability and reduce your application maintenance window.
QUESTION 2
You have a working application in the US East region. The app is a 3-tier app with a database backend – you take
regular backups of the database into OCI Object Storage in the US East region. For Business continuity; you are
leveraging OCI Object Storage cross-region copy feature to copy database backups to the US West region. Which of
the following three steps do you need to execute to meet your requirement?
A. Write an IAM policy and authorize the Object Storage service to manage objects on your behalf
B. Specify an existing destination bucket
C. Specify the bucket visibility for both the source and destination buckets
D. D. Provide a destination object name
E. E. Provide an option to choose bulk copying of objects
F. F. Choose an overwrite rule
Correct Answer: ABF
You can copy objects to other buckets in the same region and to buckets in other regions.
You must have the required access to both the source and destination buckets when performing an object copy. You
must also have permissions to manage objects in the source and destination buckets.
Because Object Storage is a regional service, you must authorize the Object Storage service for each region carrying
out copy operations on your behalf. For example, you might authorize the Object Storage service in region US East
(Ashburn) to manage objects on your behalf. Once you authorize the Object Storage service, you can copy an object
stored in a US East (Ashburn) bucket to a bucket in another region.
You can use overwrite rules to control the copying of objects based on their entity tag (ETag) values.
Specify an existing target bucket for the copy request. The copy operation does not automatically create buckets.
QUESTION 3
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.
Correct Answer: DE
STRONG CONSISTENCYWhen a read request is made, Object Storage always serves the most recent copy of the
data that was written to the system.DURABILITYObject 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 METADATAYou 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.ENCRYPTIONObject 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 4
A customer wants to do development on-premise while leveraging services such as Java Cloud, Mobile Developer
Cloud, and App Builder Services. The customer would also like to scale out the application, stretching from on-premises
to the cloud by using a common API.
Which two Infrastructure options can the customer leverage to do this? (Choose two.)
A. Oracle Cloud at Customer
B. Oracle Cloud Infrastructure Classic
C. Oracle Cloud Ravello service
D. Oracle Cloud Infrastructure
Correct Answer: AD
QUESTION 5
Which option lists Virtual Cloud Networks (VCNs) that can be peered?
A. VCN A (172.16.0.0/24) and VCN B (172.16.0.0/28)
B. VCN A (10.0.0.0/16) and VCN B (10.1.0.0/16)
C. VCN A (10.0.2.0/16) and VCN B (10.0.2.0/25)
D. VCN A (10.0.0.0/16) and VCN B (10.0.16.0/24)
Correct Answer: B
QUESTION 6
You are about to upload log file (5 TiB size) to Oracle Cloud Infrastructure object storage and have decided to use
multipart upload capability for a more efficient and resilient upload. Which two statements are true about multipart
upload? (Choose two.)
A. Individual object parts can be as small as 10 MiB or as large as 50 GiB
B. While a multipart upload is still active, you cannot add parts even if the total number of parts is less than 10,000
C. The maximum size for an uploaded object is 10 TiB
D. You do not have to commit the upload after you have uploaded all the object parts
Correct Answer: AC
With multipart upload, you split the object you want to upload into individual parts. Individual parts can be as large as 50
GiB or as small as 10 MiB. (Object Storage waives the minimum part size restriction for the last uploaded part.) Decide
what part number you want to use for each part. Part numbers can range from 1 to 10,000. You do not need to assign
contiguous numbers, but Object Storage constructs the object by ordering part numbers in ascending order.
The maximum size for an uploaded object is 10 TiB
While a multipart upload is still active, you can keep adding parts as long as the total number is less than 10,000.
QUESTION 7
Which two statements are true about encryption on Oracle Cloud Infrastructure (OCI)? (Choose two.)
A. By default, object storage and block storage are encrypted at rest.
B. A customer is responsible for data encryption in all services of OCI.
C. By default, DB Systems offers an encrypted database.
D. By default, NVMe drives are encrypted but the block volume service is not.
Correct Answer: AC

QUESTION 8
You have an instance running in a development compartment that needs to make API calls against other OCI services,
but you do not want to configure user credentials or store a configuration file on the instance. How can you meet this
requirement?
A. Create a dynamic group with matching rules to include your instance
B. B. Instances can automatically make calls to other OCI services
C. C. Instances are secure and cannot make calls to other OCI services
D. D. Create a dynamic group with matching rules to include your instance and write a policy for this dynamic group
Correct Answer: D
Dynamic groups allow you to group Oracle Cloud Infrastructure computer instances as “principal” actors (similar to user
groups).
When you create a dynamic group, rather than adding members explicitly to the group, you instead define a set of
matching rules to define the group members. For example, a rule could specify that all instances in a particular
compartment are members of the dynamic group. The members can change dynamically as instances are launched and
terminated in that compartment.
A dynamic group has no permissions until you write at least one policy that gives that dynamic group permission to
either the tenancy or a compartment. When writing the policy, you can specify the dynamic group by using either the
unique name or the dynamic group\\’s OCID. Per the preceding note, even if you specify the dynamic group name in the
policy, IAM internally uses the OCID to determine the dynamic group.
QUESTION 9
Which two tools would you use to manage Database Cloud Service (DBCS)? (Choose two.)
A. psql
B. Oracle Swingbench
C. SQL Developer
D. Oracle Enterprise Manager
Correct Answer: CD
QUESTION 10
Which two are true for achieving High Availability on Oracle Cloud Infrastructure? (Choose two.)
A. Store your database across multiple regions so that half of the data resides in one region and the other half resides in
another region.
B. Attach your block volume form Availability Domain 1 to a compute instance in Availability Domain 2 (and vice versa)
so that they are highly available.
C. Configure your database to have Data Guard in another Availability Domain in Sync mode within a region.
D. Store your database files on Object Storage so that they are available in all Availability Domains in all regions.
E. Distribute your application servers across all Availability Domains within a region.
Correct Answer: CE
