Caching will slow performance of the read queries because the cache is updated when the cache cannot find the requested data.

<h3>What is RDS?</h3>

A distributed relational database service provided by Amazon Web Services is known as Amazon Relational Database Service (or Amazon RDS) (AWS).  It is a "cloud-based" web service created to make it easier to set up, manage, and scale a relational database for use in applications. Automatic management is used for administration tasks including patching the database software, backing up databases, and enabling point-in-time recovery. A single API call to the AWS control plane on demand can scale storage and compute resources. As part of the managed service, AWS does not provide an SSH connection to the underlying virtual machine. The AWS Management Console or the Amazon Cloud Watch API both provide performance data for Amazon RDS.

Friedman (1999) argues that "we are wrong to base health promotion in all societies on a Western framework for human development
Dovator [93]

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>

If you configure any more passwords on the switch, will they be displayed in the configuration file as plain text or in encrypte
Elza [17]

Answer:

The "service password-encryption" global configuration command encrypts passwords configured before and after the command is issued.

Explanation:

A switch is an intermediate network device that is used to transfer frames to nodes on its collision domain. It operates in the Data-link layer of the OSI model.

Switches uses media address control (MAC) table, containing the MAC addresses of the nodes in the network, to determine the destination of nodes.

In the global configuration mode in a switch, the password and other protocols are configured. The service password-encryption command in the global execution mode encrypts passwords configured before and after the command.

1. Write programming code in C++ for school-based grading system. The program should accept the Subject and the number of studen
satela [25.4K]

In this program, I am using the school-based grading system and the program should accept the subject and the number of students.

Program approach:-

  • Using the necessary header file.
  • Using the standard I/O namespace function.
  • Define the main function.
  • Declare the variable.
  • Display enter obtain marks in 5 subjects.
  • Return the value.

Program:-

//header file

#include<iostream>

//using namespace

using namespace std;

//main method

int main()

{

//declare variable

  int j;

  float mark, sum=0, a;

//display enter obtain marks in 5 subjects

  cout<<"Enter Marks obtained in 5 Subjects: ";

  for(j=0; j<5; j++)

  {

      cin>>mark;

      sum = sum+mark;

  }

  a = sum/5;

//display grade

  cout<<"\nGrade = ";

  if(a>=91 && a<=100)

//display a1

      cout<<"a1";

  else if(a>=81 && a<91)

//display a2

      cout<<"a2";

  else if(a>=71 && a<81)

      cout<<"b1";

  else if(a>=61 && a<71)

      cout<<"b2";

  else if(a>=51 && a<61)

//display c1

      cout<<"c1";

  else if(a>=41 && a<51)

//display c2

      cout<<"c2";

  else if(a>=33 && a<41)

//display d

      cout<<"d";

  else if(a>=21 && a<33)

//display e1

      cout<<"e1";

  else if(a>=0 && a<21)

//display e2

      cout<<"e2";

  else

//display invalid

      cout<<"Invalid!";

  cout<<endl;

//return the value

  return 0;
