NEW QUESTION 25
Which two statements are true about Oracle Cloud Infrastructure IPSec VPN Connect?
- A. OCI IPSec VPN can be configured in tunnel mode only
- B. Each OCI IPSec VPN consists of multiple redundant IPSec tunnels
- C. OCI IPSec VPN tunnel supports only static routes to route traffic
- D. OCI IPSec VPN can be configured in trans port mode only
Answer: A,B
Explanation:
VPN Connect provides a site-to-site IPSec VPN between your on-premises network and your virtual cloud network (VCN). The IPSec protocol suite encrypts IP traffic before the packets are transferred from the source to the destination and decrypts the traffic when it arrives.
On general, IPSec can be configured in the following modes:
Transport mode: IPSec encrypts and authenticates only the actual payload of the packet, and the header information stays intact.
Tunnel mode (supported by Oracle): IPSec encrypts and authenticates the entire packet. After encryption, the packet is then encapsulated to form a new IP packet that has different header information.
Oracle Cloud Infrastructure supports only the tunnel mode for IPSec VPNs.
Each Oracle IPSec VPN consists of multiple redundant IPSec tunnels. For a given tunnel, you can use either Border Gateway Protocol (BGP) dynamic routing or static routing to route that tunnel's traffic. More details about routing follow.
IPSec VPN site-to-site tunnels offer the following advantages:
Public internet lines are used to transmit data, so dedicated, expensive lease lines from one site to another aren't necessary.
The internal IP addresses of the participating networks and nodes are hidden from external users.
The entire communication between the source and destination sites is encrypted, significantly lowering the chances of information theft.
NEW QUESTION 26
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. The maximum size for an uploaded object is 10 TiB
- B. You do not have to commit the upload after you have uploaded all the object parts
- C. Individual object parts can be as small as 10 MiB or as large as 50 GiB
- D. While a multipart upload is still active, you cannot add parts even if the total number of parts is less than
10,000
Answer: A,C
Explanation:
Explanation
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.

Which two statements are true about the Oracle Cloud Infrastructure Object Storage Service? (Choose two.)
- A. Data is stored redundantly only in a single AD.
- B. It provides strong consistency.
- C. It can be directly attached or detached from a compute instance.
- D. It provides higher IOPS than Block Storage.
- E. Data is stored redundantly across multiple availability domains (ADs).
Answer: B,E
Explanation:
Explanation
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.

You have hired a new employee to run reports from the Autonomous Data Warehouse (ADW) and are not confident in their SQL writing ability.
Into which consumer group will you assign this individual to minimize the impact of their code?
- A. Highest
- B. Low
- C. Lowest
- D. High
- E. Medium
Answer: B
Explanation:
Explanation
in ADW, The tnsnames.ora file provided with the credentials zip file contains three database service names identifiable as high, medium, and low. The predefined service names provide different levels of performance and concurrency for Autonomous Data Warehouse.
high: The High database service provides the highest level of resources to each SQL statement resulting in the highest performance, but supports the fewest number of concurrent SQL statements. Any SQL statement in this service can use all the CPU and IO resources in your database. The number of concurrent SQL statements that can be run in this service is 3, this number is independent of the number of OCPUs in your database.
medium: The Medium database service provides a lower level of resources to each SQL statement potentially resulting a lower level of performance, but supports more concurrent SQL statements. Any SQL statement in this service can use multiple CPU and IO resources in your database. The number of concurrent SQL statements that can be run in this service depends on the number of OCPUs in your database.
low: The Low database service provides the least level of resources to each SQL statement, but supports the most number of concurrent SQL statements. Any SQL statement in this service can use a single CPU and multiple IO resources in your database. The number of concurrent SQL statements that can be run in this service can be up to 300 times the number of OCPUs.
The predefined service names provide different levels of performance and concurrency for Autonomous DB Choose whichever database service offers the best balance of performance and concurrency.
Use the low database service name. to minimize the impact of their SQLs to by low consumer group

Your organization has deployed a large, complex application across multiple compute instances in Oracle Cloud Infrastructure (OCI). These compute instances also have block volume storage attached to them. You want to create a time consistent backup of these block volume storage.
Which implementation strategy should be used?
- A. Use scripts available in OCI to backup block volume storage
- B. Group volumes in a volume group first and then use available scripts in OCI
- C. Create a manual backup of each volume
- D. Group volumes in a volume group and create a manual backup of the volume group
Answer: D
Explanation:
Explanation
The Oracle Cloud Infrastructure Block Volume service provides you with the capability to group together multiple volumes in a volume group. A volume group can include both types of volumes, boot volumes, which are the system disks for your Compute instances, and block volumes for your data storage. You can use volume groups to create volume group backups and clones that are point-in-time and crash-consistent.
This simplifies the process to create time-consistent backups of running enterprise applications that span multiple storage volumes across multiple instances. You can then restore an entire group of volumes from a volume group backup.
To create a backup of the volume group
Open the navigation menu. Under Core Infrastructure, go to Block Storage and click Volumes Groups.
In the Volume Groups list, click Create Volume Group Backup in the Actions menu for the volume group you want to create a backup for.
