I'd say it's A because source file originally means "a file that contains original data," which I believe A has the closest meaning to it.
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. The recommended disaster recovery plan is
<u>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 DRsites.</u>
<u></u>
Explanation:
- Local VCN peering is the process of connecting two VCNs in the same region and tenancy so that their resources can communicate using private IP addresses without routing the traffic over the internet or through your on-premises network.
- You have a central VCN that has resources that you want to share with other VCNs.
- A VCN is a customizable private network in Oracle Cloud Infrastructure. Just like a traditional data center network, a VCN provides you with complete control over your network environment.
- A subnet, or subnetwork, is a segmented piece of a larger network. More specifically, subnets are a logical partition of an IP network into multiple, smaller network segments.
- A VCN resides in a single Oracle Cloud Infrastructure region and covers a single, contiguous IPv4 CIDR block of your choice.
Answer:
Pair Programming
Explanation:
In Extreme Programming XP, pair programming is a practice in which two programmers work together in a pair at one machine, when writing a code.
One of the two programmers is called the "driver" or developer who writes the code and supervises all the changes made to the program.
The other one is called an "navigator" or observer who provides ideas on how the program should be written, observes or reviews it the program, identify the issues or errors in the code, help in code simplifications.
The two developers implements the program, do coding, review the program and check each other's work. They both are required to be equally skilled in order to implement and test the code. This improves the process of the software development. By working in a pair and reviewing and testing the code together, they develop a better code.

Answer:
Disadvantages of public key cryptography is that : Assymetric cryptography is slower than the private key cryptography.
Explanation:
We are dealing with big data applications most of time. Almost all applications are data intensive. Private key cryptography which is also known as symmetric cryptography. Symmetric cryptography based systems are faster. Since there is no key transmitted with the data, encrypted data can be transferred over the channel or session even if the path is vulnerable or have chances of interception as the chances of decrypting the data is almost impossible.
Also, The identity of the receiver is guaranteed using the password based authentication used by symmetric crypto systems. Only the trusted receiver who has the access to the secret key can only decrypt the payload
Public Key Cryptography is slower than private key cryptography. Today’s application’s are data intensive. In case of data intensive applications , encrypting huge data will take a lot more time than that of symmetric key cryptography. Whenever Bulk data transmission is needed symmetric key cryptography is preferred. Secret key based crypto systems have proven to be more faster than any currently available assymetric key based crypto systems.
