Answer:
A. Rogue access point
Explanation:
A rogue access point is a point that is wireless and installed on a network that is safe and secure without taking any permission from a local administrative network (LAN). It could be done by an employee or a person who is a malicious attacker
Therefore according to the given situation, since there is an unauthorized AP i.e too strong which is mid of 100-acre campus so it would be a threat of Rogue access point and the same is to be communicated to the boss
Oracle, DB2, and Microsoft SQL Server are examples of RDBMS. Therefore, the <u>correct option of this question is (c)</u> i.e. RDBMS.
A software used to store, query, and retrieve data stored in a relational database is referred to as a relational database management system (RDBMS). In RDBMS, data is represented in tables with rows and columns.
The RDBMS handles administrative functions such as managing data access, storage and performance. To perform these administrative services, RDBMS provides an interface between the database, applications and users.
Some features of RDBMS are described below:
- RDBMSs are more secure, faster and easier to work with.
- More than one user can have access to RDBMS at a point of time.
- RDBMS supports distributed databases.
- RDBMS can store a vast amount of data.
- Only the data in the form of tables is managed by RDBMS.
- Data redundancy is reduced in RDBMS using primary keys and indexes.
Thus, Oracle, DB2, and Microsoft sql server are example of RDBMS.
<u>While the other ptions (a) supply chain management and (b) erp applications are not correct because:</u>
- Supply chain management is a centralized management process that handles the flow of goods and services, such as movement and storage of raw materials, inventory, finished goods, and delivery of the final product.
- Enterprise resource planning (ERP) applications refers to software used in organizations to manage day-to-day business operations such as project management, risk management and compliance, procurement, accounting and supply chain operations.

Answer:
Pros and cons of multiple inheritance
Pros
a) You categorize classes in many different ways. Multiple inheritance is a way of showing our natural tendency to organize the world. During analysis, for example, we use multiple inheritance to capture the way users classify objects.
b) By having multiple superclasses, your subclass has more opportunities to reuse the inherited attributes and operations of the superclasses.
Cons
a) If two classes have a method with the same name, the new subclass doesn't know which one to call.
b) multiple inheritance can lead to a lot of confusion when two base classes implement a method with the same name.
c) The more superclasses your subclass inherits from, the more maintenance you are likely to perform. If one of the superclasses happens to change, the subclass may have to change as well.
d) When a single subclass inherits the same attribute or operation from different superclasses, you must choose exactly which one it must use.
Explanation: Question 2
Some programming languages such as Java don’t allow you to use multiple inheritance. You must translate multiple inheritance into single inheritance or individual Java interfaces. This can be confusing and difficult to maintain because the implemented code for categorizing objects is quite different from the way the user organizes those objects. So, when the user changes their mind or adds another category, it is difficult to figure out how to program the new subclass.
