Answer c. is correct. If the LEFT keyword is replaced with the FULL keyword in the given SQL query, the total number of rows that are returned must be equal to the number of rows in the Invoices table plus the number of rows in the Vendors table.

This is because a FULL JOIN returns all rows from both tables, including those that do not have matching values in the join condition. In this case, if we perform a FULL JOIN between the  Invoices and Vendors tables, we will get all rows from both tables and if there are any non-matching rows, they will be included in the result set with NULL values. Therefore, the total number of rows that are returned will be the sum of the number of rows in the Invoices table and the number of rows in the Vendors table.

It is important to note that using a FULL JOIN can result in a large number of rows being returned, and it may not always be necessary or desirable to use it, depending on the specific requirements of the query.

It seems that your Outlook webmail has deleted many of your emails and attachment, including deleted items and sent items, but your storage is still full. This issue could be caused by a few factors:

1. Synchronization delay: Sometimes, it takes time for Outlook to update and synchronize with the server, so it may not immediately reflect the updated storage usage after deleting items. Wait for a while and then check your storage again.

2. Mail retention policies: Some organizations may have mail retention policies in place, which temporarily hold deleted items before they are permanently removed. This could result in your storage remaining full even after deleting emails and attachments. You may need to check with your IT department to see if this is the case.

3. Large emails still present: You may have overlooked some large emails with attachments still present in your account. Double-check all your folders, including the archive folder, to ensure no significant emails are contributing to your storage usage.

4. Recoverable items folder: When items are deleted from your account, they may be moved to a hidden folder called the "Recoverable Items" folder, which also takes up storage space. To clear this folder, you can empty your deleted items folder and then manually delete items from the Recoverable Items folder.

In this case, Team 2 has a larger team size and higher velocity than Team 1. However, simply comparing these numbers is not sufficient to determine which team has a higher performance.

To more accurately compare performance, we can calculate the average velocity per team member. Team 1 has an average velocity of 90 (450/5), while Team 2 has an average velocity of approximately 78 (700/9). Based on this calculation, Team 1 has a higher performance than Team 2 on a per-person basis.However, it is important to note that there may be other factors that could influence the overall performance of each team, such as the complexity and scope of the projects they are working on.

Based on the team's past velocities for iterations one to six, the most reasonable velocity estimate for the next sprint would be around 45 to 48 story points. It is important to note that this is just an estimate and there could be various factors that could affect the team's velocity for the next sprint.

To estimate the most reasonable velocity for the next sprint, we can use various methods, such as taking an average of the previous velocities or using a weighted average that gives more weight to the more recent velocities. One simple method is to use the average of the last few velocities.In this case, the average velocity of the last six iterations is (40 + 50 + 43 + 47 + 46 + 44) / 6 = 45 story points. Therefore, a reasonable velocity estimate for the next sprint could be around 45 story points.

The "cone of uncertainty" is a concept that helps visualize the reduction of ambiguity and risk as a Scrum project progresses. In the context of Scrum projects, it illustrates that the level of uncertainty is highest at the beginning of the project and gradually narrows down as more information is gathered and work is completed.

Scrum, an agile project management framework, acknowledges the uncertainty inherent in complex projects. By using iterative development cycles, called sprints, Scrum allows teams to adapt to changing requirements and priorities, thus managing uncertainty more effectively. The cone of uncertainty emphasizes the importance of early and continuous feedback through stakeholder collaboration and regular inspection of the product and processes.

As the team moves through the sprints, they learn more about the project requirements, identify potential risks, and make necessary adjustments. This continuous improvement reduces the range of possible outcomes and increases the accuracy of project estimates. Consequently, the cone of uncertainty narrows, representing a decrease in project risks and an increase in the team's confidence regarding the final product.

In summary, the cone of uncertainty demonstrates the importance of acknowledging and managing uncertainty in Scrum projects. It shows that uncertainty decreases as the project moves forward, thanks to the iterative approach and ongoing feedback, allowing teams to make more accurate predictions and improve overall project success.

Peer-to-peer (P2P) networks are best suited for sharing large files, such as music, videos, and software. They are particularly useful for individuals or organizations that need to transfer data quickly and efficiently, without relying on a central server.

P2P networks operate on a decentralized model, where each participant acts as both a client and a server. This means that users can share files directly with one another, without having to go through a central authority. This allows for faster and more efficient file transfers, since there is no need to wait for a centralized server to process requests and send files. Another advantage of P2P networks is their ability to handle high levels of traffic. Because the network is distributed across multiple nodes, there is no single point of failure. This means that the network can continue to function even if some nodes are down or overloaded with traffic.

P2P networks are also relatively secure, since files are transferred directly between users, rather than being stored on a central server that may be vulnerable to attacks. However, users should still exercise caution and use encryption and other security measures to protect their data.
