1Z0-1072-26 Storage Practice Test 2 — 15 Questions

Question 1

What is the maximum size of a single Object in OCI Object Storage?

Accepted Answer

10 TB. The maximum object size supported is 10 TiB.

Answer

Unlimited

Answer

1 TB

Answer

1 GB

Question 2

A Block Volume backup failed. Which is the most likely reason?

Accepted Answer

Insufficient IAM permissions. Block Volume backup failures are frequently caused by missing or insufficient Identity and Access Management (IAM) permissions for the user or service principal attempting to create the backup, or because the volume is currently attached and locked in an incompatible state (though permissions are the primary administrative failure point among the choices).

Answer

Bucket size limit

Answer

FastConnect is down

Answer

File system is mounted

Question 3

Which tier of Block Volume performance allows you to dynamically adjust the IOPS/GB?

Accepted Answer

Balanced. Balanced and Higher Performance tiers allow dynamic adjustment of performance settings.

Answer

Lower Cost

Answer

Archive

Answer

Ultra High Performance

Question 4

You are experiencing high latency on your FSS mount. What should you check first?

Accepted Answer

Network Security List rules. File Storage Service (FSS) in OCI relies heavily on network traffic (NFS traffic over TCP ports 2048, 2050, and 111). Incorrectly configured Network Security Lists or Network Security Groups can cause connection timeouts or high latency.

Answer

Block volume size

Answer

Object storage versioning

Answer

Bucket policies

Question 5

You want to move data from a local server to OCI Object Storage. Which tool is recommended for large-scale data migration over the internet?

Accepted Answer

OCI CLI. For large-scale data migration (typically terabytes to petabytes), especially when bandwidth is a bottleneck, the OCI Data Transfer service (Appliance or Disk) or Storage Gateway/Rclone/FastConnect is more appropriate. However, for large-scale data migration specifically over the internet where physical appliances aren't used, OCI CLI supports parallel multi-part uploads, but the best tool for massive datasets is often considered Object Storage parallel uploads via SDK/CLI or Data Transfer Service. Wait, actually, for large-scale data migration *over the internet*, OCI CLI (using `oci os object bulk-upload` or parallel multipart uploads) is indeed the correct native command-line tool, whereas Data Transfer Appliance is for offline shipping, and Web Console is not for large-scale. Let's re-evaluate: OCI Data Transfer Appliance is offline. Storage Gateway is for hybrid cloud storage integration/caching, not bulk migration. Web Console is for small files. Therefore, OCI CLI is the correct answer for online migration.

Answer

OCI Data Transfer Appliance

Answer

Web Console

Answer

Storage Gateway

Question 6

Which command-line utility is used to manage OCI Block Volumes?

Accepted Answer

oci-cli. While 'oci-cli' is used to manage the OCI Block Volume resource (provisioning, attaching, detaching), the question asks for a utility to 'manage' them. If the context implies managing the volume from within the OS (partitioning/formatting), 'fdisk' or 'lsblk' would be more appropriate. However, given the options, 'oci-cli' is the only one specific to OCI infrastructure management.

Answer

nfsstat

Answer

fdisk

Answer

mount

Question 7

When cloning a Block Volume, what must be true about the source and target volumes?

Accepted Answer

They must be in the same availability domain. Clones are created within the same availability domain as the source volume.

Answer

They must be in different regions

Answer

They must have the same size

Answer

They must use different encryption keys

Question 8

You need to share a block volume across multiple compute instances. Which configuration is required?

Accepted Answer

Block volumes cannot be shared. Block volumes do not support multi-attach. You must use a network file system instead.

Answer

Enable multi-attach flag

Answer

RAID 1 configuration

Answer

Use iSCSI with multiple logins

Question 9

How do you provide access to an object to an external user without creating an IAM account?

Accepted Answer

Pre-authenticated request. Pre-authenticated requests are specific to Oracle Cloud Infrastructure (OCI), while 'IAM account' is a general term often associated with AWS. In AWS, the correct mechanism for granting temporary access without an IAM account is a Presigned URL or AWS STS. If this is an OCI exam, 'IAM user' is typically used instead of 'IAM account', or the question needs to specify the cloud provider.

Answer

Public internet

Answer

Bucket policy

Answer

API Key

Question 10

What is the maximum number of volumes you can attach to a single compute instance?

Accepted Answer

32. The question does not specify the cloud provider or service being tested. Maximum volume attachment limits vary drastically by cloud provider and instance type.

Answer

8

Answer

Unlimited

Answer

1

Question 11

You need to automate the movement of old backups to Archive storage. Which approach is most efficient?

Accepted Answer

Lifecycle Policy. Lifecycle policies are the native, serverless, and most cost-effective way to transition objects between storage tiers based on age or other criteria, eliminating the need for compute resources or manual scripts.

Answer

Bucket replication

Answer

Manual script

Answer

Copy and delete command

Question 12

Which TWO of the following statements about Storage Gateway are correct?

Accepted Answer

It requires local cache disk space. Option B is correct because AWS Storage Gateway (in its File, Volume, and Tape Gateway configurations) always requires local cache disk space on the gateway host to buffer data before it is uploaded to AWS, improving performance and reducing latency. Option D is correct because the File Gateway configuration presents an SMB or NFS file share that maps local files directly to objects in Amazon S3 (Object Storage), allowing files to be stored as objects with their metadata. Option A is incorrect because Storage Gateway is available as a downloadable virtual appliance (VMware, Hyper-V, KVM) or as an Amazon EC2 instance, not only as a physical appliance. Option C is incorrect because Storage Gateway does not provide direct block volume mapping; block-level access is offered by services like Amazon EBS, while Storage Gateway's Volume Gateway presents iSCSI block volumes backed by S3/EBS snapshots, not direct block mapping to the underlying storage. Option E is incorrect because Storage Gateway supports both SMB and NFS for File Gateway, not SMB only.

Answer

It is a physical appliance only

Answer

It supports direct block volume mapping

Answer

It supports SMB only

Question 13

Which THREE of the following are true about OCI Block Volume backups?

Accepted Answer

Can be scheduled via policies. OCI Block Volume backups are stored in Object Storage, can be scheduled using Volume Backup Policies, and support both full and incremental backup types. This confirms options A, B, and C are correct.

Answer

Available only in US regions

Answer

Must be deleted before resizing

Question 14

Which THREE configurations are required for a functioning File Storage Service mount?

Accepted Answer

Export options. A File Storage Service (FSS) requires a mount target to provide an IP address, a subnet to define the network location, and export options to define access permissions (NFS export rules).

Answer

Public internet gateway

Answer

Block volume attachment

Question 15

Which TWO are common performance issues for Block Volumes?

Accepted Answer

IOPS saturation. Network congestion and excessive IOPS exceeding the limit are common.

Answer

Too many users

Answer

Lack of encryption

Answer

Storage bucket latency
