Option A
By illustrating relationships between different things
when part of the data in a table depends on a field in the table that isn't the table's primary key, it's known as:
The correct answer is A transitive dependence exists when a portion of the data in a table depends on a field that is not the primary key of the table.
A transitive dependency is a relationship between one non-prime property and another non-prime attribute, both of which are completely dependent on the candidate key. You can process an order based on conditions specified for a transaction thanks to transaction dependence. It gives a transaction the option to delay processing of some order lines until a number of requirements are satisfied. Other lines in the same order may also be subject to same constraints. When A depends on B and B depends on C, this is referred to as transitive dependency. Financial transactional data, such as data on insurance costs and claims, a purchase or sale, or deposits or withdrawals from a bank, are a few examples.

robin has been asked to secure network traffic between two application servers. unfortunately, the network administrator is on vacation and is not available to make any changes to the firewall between the servers. there are three applications running between the servers. currently, transmission control protocol (tcp) ports 443 and 1723 are known to be open. what is the best solution?
In the absence of the network administrator and the inability to make changes to the firewall, Robin can implement an encryption solution to secure network traffic between the two application servers. The best solution in this scenario is to use a Virtual Private Network (VPN) solution.
VPNs use encryption to secure network traffic between the two application servers by encapsulating the data within an encrypted tunnel. This encrypted traffic can then be transmitted over the open ports (443 and 1723) without being intercepted or read by unauthorized parties.
There are several VPN solutions available, both free and commercial, that can be set up quickly and easily on the application servers. Some popular VPN solutions include OpenVPN, PPTP, and L2TP/IPSec.
In conclusion, Robin can secure network traffic between the two application servers by implementing a VPN solution, even in the absence of the network administrator and without making changes to the firewall.

The changes needed to allow SSH connection to the instance are to add an outbound rule to the instance's security group, allowing outbound traffic over port 22 (the port used for SSH).
What is SSH connection?SSH (Secure Shell) is a cryptographic network protocol used to establish a secure connection between a client and a server. It is widely used for remote login to systems, allowing users to execute commands in a remote machine, and to move files from one host to another.
This will allow the instance to send and receive traffic over port 22, allowing SSH connections to be established. Additionally, if the VPC subnet's network ACL is configured to deny all outbound traffic, then it should also be updated to allow outbound traffic over port 22. This will allow the instance to send traffic over port 22 and complete the SSH connection.

prove the following: in the gale-shapley algorithm, run with n men and n women, what is the maximum number of times any woman can be proposed to?
In the Gale-Shapley algorithm, each man proposes to a woman of his choice who has not rejected him. Each woman can only be proposed to by one man at a time.
It can be shown that in the Gale-Shapley algorithm, run with n men and n women, the maximum number of women that can be proposed is n-1. This is because, in the worst case, a woman will be proposed to by all n-1 men who are not her favorite choice, before she finally accepts the one she likes best. Therefore, in stable matching, the maximum number of applications received by any woman is n-1.

A stack frame is a data structure created when a new function is called. It is used to store the state of the function's execution, including local variables and parameters. Each time a function is called, a new stack frame is allocated, and when the function returns, the stack frame is deleted. Variables allocated statically (as opposed to dynamically) live inside their respective stack frame, and are deleted automatically when the stack frame returns. The stack frames are stored in the call stack, and the order of the stack frames is determined by the order in which function calls are made. When all of the stack frames in the call stack have been returned, the program execution is complete.
