Indicators of Compromise (IOCs) include malicious IPs, domains, and file hashes.
- True
- False
Answer: True
IOCs are forensic artifacts indicating potential breaches. Used for proactive blocking, hunting, and incident response.
CSPM tools continuously monitor cloud configurations for compliance violations.
- True
- False
Answer: True
Cloud Security Posture Management automates detection/remediation of misconfigurations: public storage, weak IAM, unencrypted resources.
Micro-segmentation isolates workloads to limit lateral movement of threats.
- True
- False
Answer: True
Micro-segmentation creates granular security zones around workloads, containing breaches and limiting attacker movement. Critical for Zero Trust implementation.
An outer join returns only the rows that have matching values in both tables.
- True
- False
Answer: False
INNER JOIN returns only matching rows. OUTER JOIN (LEFT/RIGHT/FULL) returns matching rows PLUS unmatched rows from one or both tables, with NULLs for missing side. LEFT JOIN: all left table rows; RIGHT JOIN: all right table rows; FULL OUTER: all rows from both. Essential for comprehensive data analysis and reporting.
The Ayushman Bharat Digital Mission (ABDM) health ID is mandatory for availing healthcare services in India.
- True
- False
Answer: False
ABHA (Ayushman Bharat Health Account) number is voluntary and consent-based. Citizens can choose to create ABHA ID for convenient access to digital health records, but cannot be denied healthcare services for not having it. Aligns with Supreme Court privacy principles and DPDP Act requirements for voluntary consent in data processing.
Cloud bursting is a hybrid cloud strategy where applications run on-premises and 'burst' to public cloud during peak demand.
- True
- False
Answer: True
Cloud bursting allows organizations to maintain baseline capacity on-premises/private cloud and dynamically scale to public cloud during traffic spikes. Optimizes cost (pay for extra only when needed) while ensuring performance. Requires compatible infrastructure, orchestration tools, and data synchronization between environments.
Zero Trust Architecture assumes that threats can exist both outside and inside the traditional network perimeter.
- True
- False
Answer: True
Zero Trust operates on 'never trust, always verify' principle. It eliminates implicit trust based on network location, requiring strict identity verification for every access request regardless of origin. Implements micro-segmentation, least-privilege access, continuous monitoring, and assumes breach mindset for robust security posture.
PSLV has four stages using solid and liquid propulsion alternately.
- True
- False
Answer: True
PSLV has four stages: 1st and 3rd use solid propellant; 2nd and 4th use liquid propellant. Strap-on solid boosters enhance lift-off thrust. This alternating design optimizes performance for polar and sun-synchronous orbits. PSLV's reliability and versatility made it ISRO's workhorse for earth observation and small satellite launches.
NoSQL databases do not support ACID transactions at all.
- True
- False
Answer: False
Many modern NoSQL databases support ACID transactions, at least for single-document or single-partition operations. Examples: MongoDB (multi-document ACID since 4.0), Cassandra (lightweight transactions), Google Spanner (globally distributed ACID). Trade-offs exist between consistency, availability, and partition tolerance (CAP theorem).
The Digital Personal Data Protection (DPDP) Act 2023 applies to processing of digital personal data within India and also to processing outside India if it relates to offering goods/services to individuals in India.
- True
- False
Answer: True
DPDP Act 2023 has extraterritorial application: it governs processing of digital personal data (1) within India, and (2) outside India if it involves profiling or offering goods/services to individuals in India. Aligns with global frameworks like GDPR. Establishes Data Protection Board and mandates consent, purpose limitation, and data principal rights.
Serverless computing means no servers are used; code runs entirely on client devices.
- True
- False
Answer: False
Serverless (e.g., AWS Lambda, Azure Functions) abstracts server management from developers. Servers still exist but are fully managed by the provider. Developers deploy code functions that auto-scale and charge per execution. Benefits: no infrastructure management, automatic scaling, pay-per-use pricing. Not 'no servers' but 'no server management'.
Multi-factor authentication (MFA) using SMS-based OTP is considered the most secure MFA method.
- True
- False
Answer: False
SMS-based OTP is vulnerable to SIM swapping, SS7 attacks, and phishing. More secure MFA methods include: authenticator apps (TOTP), hardware tokens (YubiKey), biometrics, and FIDO2/WebAuthn. NIST guidelines recommend moving away from SMS OTP for high-security applications. Layered security approach is essential.
Homomorphic encryption allows computations on encrypted data without decrypting it first.
- True
- False
Answer: True
Homomorphic encryption enables performing calculations on ciphertext, producing encrypted results that, when decrypted, match operations performed on plaintext. Critical for privacy-preserving cloud computing, secure voting, and confidential AI inference. Still computationally intensive but advancing with research and hardware acceleration.
A clustered index determines the physical order of data in a table, and only one clustered index can exist per table.
- True
- False
Answer: True
Clustered index physically sorts table data rows based on index key values. Since data can be sorted in only one order, a table can have only one clustered index (usually on primary key). Non-clustered indexes store logical order separately with pointers to data rows; multiple non-clustered indexes are allowed.
The Aditya-L1 mission is positioned at the L1 Lagrange point to continuously observe the Sun without eclipses.
- True
- False
Answer: True
Aditya-L1 orbits the Sun-Earth L1 Lagrange point (~1.5 million km from Earth), where gravitational forces balance, allowing uninterrupted solar observation. This position avoids Earth's shadow, enabling 24/7 monitoring of solar activities, coronal mass ejections, and space weather forecasting.
In cloud computing, the customer is always responsible for security 'of' the cloud, while the provider handles security 'in' the cloud.
- True
- False
Answer: False
The shared responsibility model states: Cloud provider is responsible for security 'OF' the cloud (infrastructure, hardware, physical security). Customer is responsible for security 'IN' the cloud (data, applications, access management, OS patching in IaaS). Responsibilities vary by service model (IaaS/PaaS/SaaS).
Offline CBDC uses secure hardware for local transaction storage.
- True
- False
Answer: True
Offline mode enables transactions without internet, synchronizing when online.
One carbon credit represents one tonne of CO2 equivalent.
- True
- False
Answer: True
Carbon credits traded in compliance and voluntary markets.
Artemis Accords establish principles for peaceful lunar cooperation.
- True
- False
Answer: True
Artemis Accords signed by India in 2023 for cooperative exploration.
Hash-based signatures are quantum-resistant but have larger signature sizes.
- True
- False
Answer: True
SPHINCS+ uses hash functions believed quantum-resistant. Trade-off: larger signatures.
