Answer» (i) Divisibility rule for 4 is last two digit of a number is divisible by 4. ∴ The number 24308 is divisible by 4. Thus, Least value of A for that 234A8 is divisible by 4. (ii) The given number is 98A4. For divisible by 4, Last two digit of number must be divisible by 4. And for divisible by 9, Sum of digits of that number is divisible by 9. i.e., A4 is divisible by 4. Possibilities for A are 0,2,4,6,8 And 9+8+A+4 = 21 + A is divisible by 9. Possibilities for A are 6. Hence, The number 98A4 is divisible by 4 and 9 is A = 6. |

The novel acknowledges modern thoughts valuing traditional roots. Discuss. उपन्यास आधुनिक विचारों को स्वीकार करता है साथ-साथ जो स्वस्थ परम्पराओं का मूल्य है उसका भी इनके साथ समावेश करता है। चर्चा कीजिए। |
|
Answer» Rama Mehta loves and honours progress and modern scientific view of life. However she does not like that the valuable Indian traditions and customs should be sacrificed at the altar of modernity. Man, according to her, should have rational, scientifc and modern outlook on life. But it does not mean that the healthy traditions and customs that we have inherited from our forefathers have lost their values wholly. Some of them may not be as relevant today as they used to be in those days. But we cannot afford to reject them outright. Most of them still hold good. We should honour them and remember that without them we have no identity. रमा मेहता जीवन के प्रति उन्नति के आधुनिक वैज्ञानिक दृष्टिकोण को प्यार करती हैं तथा उसका सम्मान करती हैं। परन्तु वह यह पसन्द नहीं करती हैं कि मूल्यवान भारतीय परम्पराओं और रीति-रिवाजों को आधुनिकता की वेदी पर चढ़ा दिया जाये। उनके अनुसार मनुष्य का जीवन के प्रति तर्कपूर्ण, वैज्ञानिक तथा आधुनिक दृष्टिकोण होना चाहिये। परन्तु इसका अर्थ यह नहीं है कि जो स्वस्थ परम्परायें और रीति-रिवाज हमने अपने पूर्वजों से प्राप्त किये हैं उन्होंने अपने मूल्य पूर्णत: खो दिये हैं। उनमें से कुछ आज इतने प्रासंगिक शायद न हों जितना वे उन दिनों हुआ करते थे। परन्तु उन्हें पूर्णत: नकार देने से हमारा काम नहीं चल सकता। उनमें से अधिकांश का अभी भी वही मान और मूल्य है। हमें उनका सम्मान करना चाहिये और याद रखना चाहिये कि उनके बिना हमारी कोई पहचान नहीं है। |

Which of the following is a form of DoS attack?(a) Vulnerability attack(b) Bandwidth flooding(c) Connection flooding(d) All of the mentioned |
|
Answer» The correct option is (d) All of the mentioned Easiest explanation: In a DoS attack, the attacker won’t let the victims access the network by using a certain method that ensures that an essential network resource is unavailable to the victim. In vulnerability attack, the attacker exploits any obvious vulnerable entity in the network to deny the victim access into the network. In bandwidth flooding, the attacker floods the victim with a huge flow of packets and uses up all the bandwidth. In connection flooding, the attacker floods the victim network with a huge number of connections, so that, no other machine can connect to it. |

|
Answer» Right answer is (c) Connection flooding To elaborate: In Vulnerability attack, the attacker exploits the vulnerable control points of the network to deny access to the victims. In Bandwidth flooding, the attacker intentionally uses up all the bandwidth by flooding the victim with a deluge of packets and makes sure that the victim can’t use any bandwidth. In UDP flooding, too many UDP packets are sent by the attacker to the victim at random ports. |
