22 Oct 2026Science & TechnologyIndigenisation of technology and developing new technology; cyber security.
Foreign technology dependence and operational sovereigntyCritical services → foreign-controlled networks, software & equipment Ownership ≠ technical control or assured service continuity
21 Oct 2026Science & TechnologyStrategic technology supply chains — indigenisation of technology; effects of liberalisation and changes in industrial policy.
Dual-use export controls and India’s infrastructure resilienceConcentrated machinery and technology supplies can become strategic vulnerabilities. Dual-use export controls can affect civilian infrastructure and industrial upgrading.
22 Oct 2026Science & TechnologyTechnology sovereignty – control planes and critical-service continuity
Domestic ownership and data localisation do not necessarily ensure technological sovereignty. Critically examine with reference to satellite services, cloud computing and digital payments in India. (250 words, 15 marks)22 Oct 2026Science & TechnologyWeb public key infrastructure – intermediate certificates and key entropy
Consider the following statements about web public key infrastructure: 1. A certificate authority's digital signature helps authenticate the binding between a public key and a website identity. 2. A private key is cryptographically strong merely because its encoded representation occupies a large number of bits. 3. Compromise of an intermediate certificate authority does not necessarily imply compromise of the root authority's private key. Which of the statements given above are correct? Select the correct answer using the code given below:22 Oct 2026Science & TechnologySatellite navigation – minimum measurements for standalone positioning
For an ordinary satellite-navigation receiver without an independently synchronised clock or external positioning constraints, what is the minimum number of satellites from which usable signals are ordinarily required to determine three-dimensional position and receiver clock offset?21 Oct 2026Science & TechnologyOpen-weight AI — parameters, licensing and deployment
Consider the following statements about open-weight artificial intelligence models: 1. Model weights are numerical parameters that influence how a trained model processes inputs. 2. Releasing model weights necessarily makes the training data and training code publicly available. 3. Subject to technical and licensing requirements, downloadable weights may permit deployment on an organisation’s own infrastructure. Which of the statements given above are correct? Select the correct answer using the code given below:21 Oct 2026Science & TechnologySolar spectroscopy — Doppler measurement of plasma motion
Which one of the following observations most directly enables a solar spectrograph to infer the line-of-sight velocity of emitting plasma?17 Oct 2026Science & TechnologyTandem photovoltaics and upstream polysilicon
With reference to solar photovoltaic technology, consider the following statements: 1. A photovoltaic cell uses a semiconductor to convert incident light into electrical energy. 2. A tandem solar cell can combine absorbers with different band gaps to utilise different parts of the solar spectrum. 3. Polysilicon production and the assembly of finished solar modules are the same manufacturing stage. Which of the statements given above are correct?Showing published editions from the last 90 days.

17 Oct 2026Science & TechnologyCredential exposure and least-privilege cloud access
Consider the following pairs of cybersecurity weaknesses and corresponding corrective controls: 1. Credentials exposed in a public code repository — Revoke and rotate the exposed credentials 2. Cloud-service roles with excessive permissions — Restrict privileges to those required for the task 3. Failure to notice unauthorised access — Maintain access logs and monitor anomalous activity How many of the pairs given above are correctly matched?
