What is an example of a composite key in a database table?
InvoiceID
CustomerID
ProductID
OrderID + ProductID
Answer:
b
Explanation:
OrderID + ProductID is an example of a composite key in a database table. The correct option is 4.
What is composite key?A composite key is a key in a database table that consists of two or more columns that uniquely identify each row.
In a database table, a composite key is the combination of OrderID and ProductID in a table that tracks sales transactions.
Because a single order can contain multiple products and multiple orders can contain the same product, neither column can uniquely identify a row by itself.
However, by combining the two columns, each row can be uniquely identified, ensuring that the data is accurate and complete.
Similarly, a combination of CustomerID and ProductID might be used in a sales system to track the products purchased by each customer.
Thus, the correct option is 4.

How does a filmmaker decide which events to include in a documentary?
Answer:
A documentary is a film based on facts in which the maker tries to portray an aspect of reality, such as politics, science, society or history, nature or the personal perception of the documentary maker.
Documentaries are informative in nature. Sometimes documentaries attempt to provide an objective picture of a subject. There is a lot of debate about what is objective, because the documentary maker chooses his images from reality, which is in itself a subjective act. In a creative author's documentary, the emphasis is on the subjective vision of the filmmaker.
Therefore, the documentary maker will select the events to include in the documentary according to the approach he or she wants to give to it, be it objective or subjective.

Answer:

Explanation:
nadine is the systems administrator for a network with a single subnet. The subnet uses 192.168.1.0 with a mask of 255.255.255.0. The network has 10 servers running Windows Server. Srv1 currently provides both DHCP and DNS services. Nadine wants to increase the fault tolerance for her DHCP servers. She installs a new server, Srv11, and configures it for DHCP. She configures a scope on Srv11 to match the scope on Srv1 and then excludes half of the addresses in the scope on Srv1 and the other half of the addresses on the Srv11. Nadine decides to test her solution and shuts down Srv1. As a test, she forces a workstation to release its IP address and request a new one. She finds that the workstation has the IP address 169.254.0.15 with a mask of 255.255.0.0. What should Nadine do to fix the problem?
Answer:
Authorize Srv11
Explanation:
In order to fix this problem, Nadine should Authorize Srv11. The problem is most likely being caused due to failure of authorization of the server. This would prevent this server from being on the same scope as Srv1 and therefore, it is why the IPaddress being given is different. DHCP is an automatic protocol and would not be able to provide an IP address in the same scope if the server is not Authorized to do so.
