Question Discussion & Solution

Important Points

Email bomb

It is an attack on your inbox that involves sending massive amounts of emails to your address. Sometimes these messages are complete gibberish, but more often they’ll be confirmation emails for newsletters and subscriptions.

Additional Information

Spoofing 

It is the act of disguising a communication from an unknown source as being from a known, trusted source. Spoofing can apply to emails, phone calls, and websites, or can be more technical, such as a computer spoofing an IP address, Address Resolution Protocol (ARP), or Domain Name System (DNS) server.

Smurf Attack

It is a form of a DDoS attack that causes packet flood on the victim by exploiting/abusing ICMP protocol. When deployed, large packets are created using a technique called “spoofing”. The phony source address that is now attached to these packets becomes the victim, as their IP is flooded with traffic. The small ICMP packet generated by the tool causes big trouble for a victim, hence the name Smurf.

Ping storm

It is a condition in which the Internet ping program is used to send a flood of packets to a server to  test its ability to handle a high amount of traffic or, maliciously, to make the server inoperable

Hence Option 1 is correct

The correct answer is connective.

• Blood is a type of connective tissue. 

Key Points

• ​Connective tissue
  • This is a kind of biological tissue that supports, connects, or separates different types of tissues and organs of the body.
  • Examples- Tendons, ligaments, cartilage, bone, blood.
• Blood has a fluid (liquid) matrix called plasma, in which red blood corpuscles (RBCs), white blood corpuscles (WBCs), and platelets are suspended.
  • The plasma contains proteins, salts, and hormones.
  • Blood flows and transports gases, digested food, hormones, and waste materials to different parts of the body.

Additional Information

• Epithelial tissue:
  • The epithelial tissues are formed by cells that cover the organ surface such as the surface of the skin, the airways, the reproductive tract, and the inner lining of the digestive tract.
• Muscular tissues:
  • Muscular tissue is a soft tissue that composes muscles.
  • Skeletal muscle (voluntary muscles), cardiac muscle (involuntary muscles) are examples of it.
• Nervous tissue:
  • The main components of the nervous system are the brain, spinal cord, and nerves which regulate and control body functions.
  • It is made up of neurons that have important functions in the nervous system.

Key Points

 An array is defined as the collection of similar types of data items stored at contiguous memory locations. Arrays are the derived data type in C programming language which can store the primitive type of data such as int, char, double, float, etc. C array is beneficial if you have to store similar elements.

int array[] = {2, 3, 4, 5}; This array storage be like, 

The above array at index I can be accessed by, a[i], i[a], *(a+i) or *(i+a) all the above representations all are equal and gives the i th index value.

printf(%d', 2[array]); So, it gives the 2^nd  index value. i.e 4.

Hence the correct answer is 4.

Additional InformationProgram: 

#include
int main()
{
    int arr[] = { 2, 3, 4, 5 };
    printf("%d ",arr[2]);
    printf("%d ",2[arr]);
    printf("%d ",*(2+arr));
    printf("%d ",*(arr+2));
    return 0;
}

Output: 4 4 4 4

So above given 2^nd index value is 4 for all above print statements.

The correct answer is 60 : 40.

• In Rajasthan, the funding pattern of Pradhan Mantri Krishi Sinchai Yojana (PMKSY) between centre and state is 60 : 40.

Additional Information

• Pradhan Mantri Krishi Sinchai Yojana (PMKSY)

  • A budget of ₹53 billion in a time span of one the year 2015-2016 has been allocated to this scheme.
• The major objective of PMKSY
  • The major objective of PMKSY is to achieve convergence of investments in irrigation at the field level, expand cultivable area under assured irrigation, improve on-farm water use efficiency to reduce wastage of water, enhance the adoption of precision-irrigation and other water saving technologies (More crop per drop), enhance recharge of aquifers and introduce sustainable water conservation practices by exploring the feasibility of reusing treated municipal wastewater for peri-urban agriculture and attract greater private investment in the precision irrigation system.​
