Defence Current Affairs Quiz: 3 October 2026

The correct answer is the United Republic of Tanzania. The Assembly and the meetings held around it are taking place at Arusha, a city in that country, from 5 to 9 October 2026, and the Indian Parliamentary Delegation left for Arusha for this purpose. Option A, Kenya, is a neighbour of Tanzania and a frequent venue for conferences in East Africa, but it is not the host this time. Option C, Uganda, and option D, Ethiopia, are also East African states and are offered because they look plausible; neither hosts the Assembly. Aspirants should hold the city and the country together, since questions are set on either one. It is also worth noting that the theme chosen for this edition is 'Enhancing good governance and empowering communities through inclusivity, trust and opportunities for all', and that the Indian team is led by the Deputy Chairman of the Rajya Sabha.

The correct answer is 5.56 km. That is the span over which the country's first free-space Quantum Key Distribution link was established, between the BISAG-N campus and IIT Gandhinagar, in a field trial run on the night of 27 and 28 September. Options A, C and D are wrong because each names a distance other than the one achieved, and in a question of this type the figure itself is the whole answer. The distance matters for a reason worth understanding rather than merely memorising: sending single photons through open air means fighting turbulence, scattering and the problem of keeping a narrow beam locked on a receiver kilometres away, which is why a Pointing, Acquisition and Tracking system was needed. The team described the result as a step towards longer-distance quantum-secure networks and towards quantum communication by satellite, so later figures may well be larger.

The correct answer is the Philippines. The ASEAN-India Maritime Exercise was conducted there, with INS Sahyadri and INS Kulish representing the Indian Navy through both the Harbour Phase and the Sea Phase. Options A, C and D are all members of the same regional grouping, which is exactly why they work as distractors in a question on an ASEAN exercise, and a candidate who recalls only that the exercise was held somewhere in South-East Asia can be caught by any of them. The venue is worth attaching to the name of the exercise in memory, because a maritime exercise of this kind is usually identified by its host, its participating ships and its theme together. Here the theme was Anchored in Trust, United at Sea, and the Indian participation was framed by the Act East Policy.

The correct answer is the Deputy Chairman of the Rajya Sabha, Shri Harivansh, who heads the nine-member team that went to Arusha. He is to sit in the Governing Council of the Inter-Parliamentary Union, speak in the General Debate and in the debate on the emergency item, and attend the hearing of those who are candidates for the post of IPU President. Option A, the Speaker of the Lok Sabha, often leads Indian parliamentary teams abroad, which makes it a tempting choice, but the delegation this time is led by the Rajya Sabha Deputy Chairman. Option C, the Leader of the Opposition in the Lok Sabha, holds no such role here. Option D, the Minister of External Affairs, belongs to the government and not to a parliamentary delegation; the Assembly is a meeting of parliaments rather than of governments, and the announcement came from the Rajya Sabha Secretariat.

The correct answer is QNu Labs, BISAG-N and IIT Gandhinagar. QNu Labs supplied the hardware QKD device Armos, BISAG-N contributed the post-quantum cryptography platform Vedic Kavach along with one end of the link, and IIT Gandhinagar hosted the other end and provided the field setting. Option A is wrong because neither the space agency nor the defence research organisation is named in this demonstration, although both work on allied technologies. Option C is wrong because the telecom research centre, the public sector electronics firm and the Bengaluru institute named there had no part in this particular trial. Option D is wrong on the same ground. The partnership is worth remembering as a shape as much as a list: a private quantum technology firm, an autonomous scientific society under the Ministry of Electronics and Information Technology, and an IIT supplying the academic and field component.

The correct answer is Anchored in Trust, United at Sea. Themes are among the most heavily tested details in questions on exercises and summits, because they are specific, short and easy to confuse with a plausible alternative. Options B, C and D are wrong because none of them was the theme adopted for this edition, although each is the kind of phrase that attaches itself to maritime cooperation and so reads convincingly. Link the theme to the rest of the package when you learn it: the exercise is the ASEAN-India Maritime Exercise, the host is the Philippines, the Indian ships are INS Sahyadri and INS Kulish, and the two phases are the Harbour Phase and the Sea Phase. The Navy said the two phases together reinforced trust and improved interoperability among the participating forces, which echoes the theme itself.

The correct answer is the election of the United Nations Secretary-General, which has nothing to do with this Assembly. The Inter-Parliamentary Union is the global body of national parliaments and runs its own affairs, so an election at the United Nations is not on its programme. Options A, B and C are all forums the leader of the Indian delegation, Rajya Sabha Deputy Chairman Shri Harivansh, is scheduled to attend: the Governing Council, which takes the organisation's decisions; the General Debate, held on the theme of the Assembly; and the debate on the emergency item, which allows a pressing world question to be taken up at short notice. He is also to attend the hearing of the candidates standing for the post of IPU President. Other members of the Indian team will join panels and workshops on democracy, maritime security, counter-terrorism, critical minerals, artificial intelligence and climate change.

The correct answer is 230 to 260 bits per second, with the Quantum Bit Error Rate held below 5%. Both numbers describe the quality of the link: the key rate is how fast fresh secret material can be produced for encryption, and the error rate measures how often a photon is read wrongly, which in quantum key distribution also signals whether anyone has interfered with the channel. Options B, C and D each pair figures that were not those recorded, and a candidate who remembers only one of the two values can still be caught by a mismatched pair, so the two should be learnt together. The keys produced at this rate were handed to the Vedic Kavach platform, where post-quantum cryptography completed the encryption and decryption of test messages from end to end.

The correct answer is Mutual and Holistic Advancement for Security and Growth Across Regions. Acronyms with a full form of this length are standard objective-paper material, and the safest way to carry them is word by word rather than by sense, because every distractor here is built to sound right. Option A keeps the regional ending but replaces the opening words. Option C swaps in humanitarian assistance, which appears in this story as a Sea Phase drill rather than as part of the acronym. Option D uses harbour and sea, again drawn from the phases of the exercise, to produce something that reads plausibly but is not the expansion. The Indian Navy's participation in AIME 2026 was placed within this vision and within the Act East Policy, so the two frameworks are worth remembering as a pair.

The correct answer is Vedic Kavach, the post-quantum cryptography platform built by BISAG-N. The keys produced by the quantum link were integrated with it, and test messages were then encrypted and decrypted from end to end. Option A is a trap worth noticing: Armos is also part of this story, but it is QNu Labs' hardware QKD device that generates the keys over the free-space optical channel, not the software platform that consumes them. Keeping the two names apart is the main thing this question tests. Option C is wrong because no platform of that name features in the demonstration. Option D is wrong as well and is simply a plausible sounding invention. Remember the division of labour: Armos is hardware and makes the keys, Vedic Kavach is software, adds post-quantum cryptography and quantum random number generation, and uses them.

The correct answer is live submarine-launched missile firing, which was not part of the drills described. The Sea Phase consisted of coordinated exercises in Humanitarian Assistance and Disaster Relief, Visit-Board-Search-Seizure and Underway Replenishment, with helicopter work covering cross-deck landings, vertical replenishment and casualty evacuation. Options A, B and C are therefore wrong answers to a question asking what was not included, since each of them was in fact carried out. The pattern of drills tells you what the exercise was for: boarding operations and disaster relief are the tasks regional navies share in peacetime, and replenishment at sea is what allows ships to stay deployed. Notice that the question asks for the exception, a form that regularly costs marks to candidates who read only the first half of the sentence.
