Answer:
Three (3)
Explanation:
Explanation of the three basic terms here - Knowledge consistency checker, hops and domain controller - will give a clearer answer and explanation to the question as follows;
<em>Domain controller</em> : is a server controller that gives access or controls to users on computer networks by first responding to their authentication requests and verifying those users. In other words, a domain controller is a network security manager.
<em>Hop</em> : A hop is simply the passage of data packets from one network to another. As a packet moves from its source to destination, it moves from router to router. The number of such routers that the packet passes through is called a hop.
<em>The Knowledge Consistency Checker (KCC)</em> : It is the job of the KCC to ensure that these domain controllers participate in the replication promptly and orderly. Replication means copying data from one location to another (within a network or among networks). The KCC ensures that the maximum number of hops permitted is does not exceed 3. i.e no domain controller is more than 3 hops from any other domain controller within a network.
Note: Replication is of two types - intrasite (among all domain controllers within a site) and intersite (among all domain controllers in different sites), and the KCC can manage both type of replication. Also, by default, at every 15 minutes interval, a domain controller generates a replication topology (a logical map that dictates the domain controllers that will replicate with each other).

Answer:
The image of truth table is attached.
Explanation:
In the truth table there is a separate table for the expression (A+B).C and for the expression (A.C)+(B.C) you can see in the truth table that the columns of (A+B).C is having same values as the (A.C)+(B.C).Hence we can conclude that (A+B).C is equal to (A.C)+(B.C).
Answers with Explanation:
A. Give at least two reasons why he believes this.
Friedman believes that health promotion based on Western framework for human development<em> unfairly criticizes the other cultures in the society.</em> Western framework values intellectual and economic achievements alone, which then <em>results to putting a great expense on the other essential human qualities.</em>
B. What crisis does he believe is happening in the most economically developed countries?
The crisis that is happening in the most economically developed country is the <em>devaluing of the other aspects which other human beings value in terms of individuality or families.</em>
C. What does he recommend to improve the programming for adolescent health?
He recommends that if changes were to be implemented for adolescent's health, <u>these have to be properly assessed regarding their effect on the adolescent's development,</u> including his/her family and other social relationships. Next is to check whether<u> it doesn't conflict with the adolescent's culture in the community that he belongs</u>. If it does, then it is essential to change it or find <em>another way which fosters</em><em> </em><em>the same goal.</em>
Answer:
Explanation:
Duplicate tuples are not allowed in a relation because the specifications of the constraints of the regional integrity are violated, especially the main constraint that states that there can be no identical values for the attributes of two tuples at any database relation state.
Also, duplicate tuples are not allowed in a relation due to the fact that they lead to redundancy of the data base which in turn, slowing down the speed of the database when data processing such as inserting, querying, updating, deleting, etc are being performed.
