Answers
1. (d)
Statement 1 is incorrect. The Indian Computer Emergency Response Team (CERT-IN) works under the Ministry of Communications and Information Technology, Government of India. It deals with cyber security and serves as the national agency to perform certain functions.
The objectives of the Indian Computer Emergency Response Team are:
Preventing cyber attacks against the country's cyber space.
Responding to cyber attacks and minimizing damage and recovery time reducing national vulnerability to cyber attacks.
Enhancing security awareness among common citizens
Statement 2 is incorrect. The Indian Computer Emergency Response Team (CERT-IN) identifies all forms of cyber security incidents send issues information regarding it. The incidents are reported on a daily basis and alert computer system users about the vulnerability of the system. Recently, multiple vulnerabilities in apple iOS were detected and reported by it. The most recent vulnerability note issued by ICERT is on the multiple vulnerabilities in StrandHogg.
StrandHogg is a malware. It can allow the Cybercriminals to listen to microphone, steal login credentials, take photos using the camera, read SMS and even access photos.

2. (a)
Statement 1 is correct. The Transiting Exoplanet Survey Satellite (TESS) is a new planet-hunting spacecraft. It is expected to find thousands of new exoplanets orbiting nearby stars. NASA's planet-hunting satellite is on the first-of-its-kind mission to find new worlds beyond our solar system.
Statement 2 is incorrect. The Indian Space Research Organisation is not a party to this mission.

3. (b)
Statement 1 is incorrect. The Polar Satellite Launch Vehicle (PSLV) is a third-generation launch vehicle. It is India's one of the most reliable and the most popular launch vehicles, has been in service for over twenty years. The historic Mars Orbiter Mission (MOM), and the Indian Regional Navigation Satellite System (IRNSS) were carried out by it. Hence, statement 2 is correct.
First Generation: Satellite Launch Vehicle
Second Generation: Augmented Satellite Launch Vehicle (ASLV)
Fourth-stage Launch Vehicle: Geosynchronous Satellite Launch Vehicle (GSLV)
4. (c)
Both the statements are correct. A rocket engine is required to upthrust a missile, a spacecraft, an aircraft or other vehicles that are sent into space. Its efficiency is more in space than in the atmosphere. They are lightweight, powerful and capable of generating large accelerations.
A missile is a self-propelled precision-guided system. They consist of four components: targeting or missile guidance system, flight system, engine and warhead.
5. (d)
All are components of Government's Cloud Computing:
Five essential characteristics of cloud computing - on-demand self-service, ubiquitous network access, metered use, elasticity, and resource pooling.
