RRB Technician Grade I (Signal) 2024, 2025 PYQs

Concept: When a file is attached as a link (Outlook with OneDrive/SharePoint), the permission drop-down offers only viewing/editing type options.

1. Standard options: "Can edit" and "Can view" (and settings such as organisation / anyone / specific people).
2. "Can delete" is not a standard sharing permission — deletion is controlled by ownership, not by share links; but "Can ReView" is not even a real option (it is a made-up word).
3. Hence the option that is NOT a permission option is "Can ReView".

Yaad rakhein: Share-link permissions = Can edit / Can view only.

Answer: (A) Can ReView

Concept: In PowerPoint the "New Slide" button lives in the Slides group of the Home tab.

1. Home → Slides → New Slide (shortcut Ctrl + M).
2. The Insert tab also has New Slide, but the question asks which tab you would use — Home is the standard answer; Design and Transitions have nothing to do with adding slides.

Yaad rakhein: Ctrl + M = new slide; it sits on the Home tab.

Answer: (D) Home

Concept: System software runs and manages the hardware (OS, utilities, firmware, drivers); application software performs user tasks.

1. Operating system, utility software (antivirus, disk cleanup) and firmware are all system software.
2. Microsoft Office (Word, Excel, PowerPoint) is application software used by the end user.

Yaad rakhein: If you "use it to do your work", it is application software.

Answer: (B) Microsoft Office

Concept: Each social network allows a different number of characters in the bio/about field.

1. Instagram bio – 150 characters; Twitter (X) bio – 160 characters — these two fix the matching.
2. LinkedIn "About" (summary) allows the longest text, in the thousands of characters; Facebook short bio is the 255-character field.
3. So I-A, II-B, III-C, IV-D.

Yaad rakhein: Insta 150, Twitter 160, LinkedIn longest.

Answer: (C) I-A, II-B, III-C, IV-D

Concept: Real-time (on-access) protection is the antivirus component that runs continuously in the background.

1. It scans every file as it is opened, downloaded, copied or executed and blocks malware immediately.
2. Manual/on-demand scan (option C) runs only when started by the user; updates and backups are separate features.

Yaad rakhein: Real-time = always watching, no click needed.

Answer: (A) Continuously monitors and scans files for malware

Concept: Malware consumes resources, corrupts data and destabilises the system.

1. Slow performance and erratic behaviour (pop-ups, programs opening on their own) are classic signs.
2. Unexplained data loss and frequent crashes/freezes are also typical infection symptoms.
3. All four listed symptoms indicate possible infection.

Yaad rakhein: Slow, strange, lost, crashed — all four = malware warning.

Answer: (A) I, II, III, and IV

Concept: A pie chart shows how a single whole is divided into parts (percentages of a total).

1. Each slice is proportional to its share of the whole — ideal for "parts of a whole".
2. Line chart → trends over time; Column chart → compare values across categories; Histogram → frequency distribution.

Yaad rakhein: Share/percentage of total → Pie.

Answer: (A) Pie Chart

Concept: CSV (Comma-Separated Values) is a plain-text format that every spreadsheet program can open.

1. .xlsx and .xlsb are Microsoft formats — not guaranteed to open in all spreadsheet software.
2. .pdf is a fixed document, not an editable spreadsheet.
3. .csv keeps only the cell values (no formulas/formatting) but is universally compatible.

Yaad rakhein: Universal exchange of tabular data = CSV.

Answer: (D) Comma-separated values (.csv)

Concept: Excel stores recognised dates as serial numbers; anything it cannot parse as a date is stored as plain text.

1. An unrecognised date (e.g. "2024.13.45") is left-aligned and treated as text — no error, no auto-correction.
2. Date functions and sorting will then not work on that cell until it is re-entered in a valid format.

Yaad rakhein: Left-aligned = text; right-aligned = number/date.

Answer: (A) MS-Excel treats it as a text.

Concept: Printing from Chrome on Android follows the official sequence: open app → open page → More (⋮) → Share → Print → choose printer → settings → Print.

1. Open the Chrome app (1) and open the page you want to print (4).
2. Tap More → Share (3) and select Print (5).
3. Select a printer at the top (7), change settings with the Down arrow if needed (6), and finally tap Print (2).

Trick: The last action is always the actual Print button, so the sequence must end with 2 – only option (C) does.

Answer: (C) 1, 4, 3, 5, 7, 6, 2

Concept: In MS PowerPoint the Animations tab applies visual effects (Entrance, Emphasis, Exit, Motion Paths) to objects such as text, pictures and shapes.

1. Animations → effects on objects (Fly In, Appear, Spin …).
2. Transitions → effect only while moving from one slide to the next; Layouts and Designs decide arrangement and theme, not effects.

Yaad rakhein: Objects → Animations; between slides → Transitions.

Answer: (C) Animations

Concept: In MS Word, Ctrl + H opens the Find and Replace dialog box with the Replace tab selected.

1. Ctrl + F → Find (Navigation pane), Ctrl + H → Replace, Ctrl + G → Go To – all three are tabs of the same dialog box.
2. Header/Footer, Language and Bullets have no single Ctrl-letter shortcut.

Yaad rakhein: H = cHange (replace).

Answer: (D) The Find and Replace dialog box

Concept: INF (Setup Information) files tell Windows how to install drivers/software. The Setup API's INF-file processing functions cover every stage of that job.

1. They open and close an INF file (SetupOpenInfFile / SetupCloseInfFile) and read information from it (SetupGetLineText etc.).
2. They also fetch source-file and target-directory details for copy operations and finally perform the install actions listed in an INF section (SetupInstallFromInfSection).
3. Hence all four statements are correct.

Yaad rakhein: INF functions = open/close + read info + copy details + install – all four.

Answer: (B) 1, 2, 3 and 4

Concept: In MS Word, keyboard access keys (Alt + letter) reach ribbon commands: Alt, N (Insert tab), X (Text Box).

1. Press and release Alt, N, then X to open the Text Box gallery (iii).
2. Use the arrow keys to pick a text box and press Enter (ii).
3. Type the text (iv) and press Esc to return to the document (i).

Trick: Open → choose → type → exit, i.e. iii, ii, iv, i.

Answer: (D) iii, ii, iv, i

Concept: Microsoft's desktop operating systems in order: Windows XP → Vista → 7 → 8 → 8.1 → 10 (2015) → 11 (5 October 2021).

1. Windows 11 is the latest released version; Windows 10 support ended in October 2025.
2. Windows 12 has not been released; Vista is an old 2007 version.

Yaad rakhein: Latest Windows = 11 (2021).

Answer: (D) Windows 11

Concept: In MS Word, Design tab → Paragraph Spacing offers built-in presets: Default, No Paragraph Space, Compact, Tight, Open, Relaxed and Double, plus Custom Paragraph Spacing.

1. Compact, Open and No Paragraph Space all appear in this gallery.
2. "Compatible Spacing" is not a Word paragraph-spacing preset – it is not offered anywhere in the list.

Yaad rakhein: Word spacing presets – No space, Compact, Tight, Open, Relaxed, Double.

Answer: (D) Compatible Spacing

Concept: A search engine indexes web pages and returns results for a query.

1. Google (launched 1998) handles roughly 90% of all web searches worldwide, far ahead of Bing, Yahoo and DuckDuckGo.
2. Bing (Microsoft) is a distant second; DuckDuckGo is known for privacy, not market share.

Yaad rakhein: "To google" has become a verb – that shows its dominance.

Answer: (C) Google

Concept: Task Manager (Ctrl + Shift + Esc) shows running programs; a hung application is closed with End task.

1. The Processes tab lists Apps and background processes with their status ("Not responding") – select the app and click End task.
2. Services controls Windows services, Startup controls auto-start programs, Details shows raw process names (end task is possible there too, but the standard answer for ending an application is Processes).

Yaad rakhein: Hung app → Task Manager → Processes → End task.

Answer: (B) Processes

Concept: Integer part – divide by 2 and read remainders upward; fractional part – multiply by 2 and read the integer digits downward.

1. $26\to$ remainders $0,1,0,1,1$ (bottom to top) $\Rightarrow 11010$.
2. $0.85\times 2=1.70$ (1), $0.70\times 2=1.40$ (1), $0.40\times 2=0.80$ (0), $0.80\times 2=1.60$ (1), $0.60\times 2=1.20$ (1), $0.20\times 2=0.40$ (0) $\Rightarrow \mathrm{.110110}$.
3. ${26.85}_{10}\approx {11010.110110}_2$.

Trick: $26=16+8+2\Rightarrow 11010$; only options (C) and (D) start with 11010, and $0.85>0.5$ means the first fractional bit is 1 → (D).

Answer: (D) 11010.110110

Concept: A WAN links many distant sites, so it needs multiple alternative paths for reliability.

1. Mesh topology connects nodes through several redundant links – if one link fails, data takes another route; the Internet backbone is a (partial) mesh.
2. Bus, ring and star are LAN topologies with a single point/path of failure, unsuitable over long distances.

Yaad rakhein: LAN → star; WAN → mesh.

Answer: (D) Mesh
