Obsidian for knowledge management

• A. .docx files stored in a proprietary database
• B. Plain Markdown (.md) files stored in a local folder ✓
• C. HTML files synced to a cloud server
• D. JSON files inside a single hidden archive

Why: Obsidian stores notes as plain Markdown (.md) files in a folder you choose (called a vault), which keeps your data portable and readable in any text editor.

• A. A password-protected folder that encrypts notes automatically
• B. A cloud account that stores backups of your notes
• C. A folder on your computer that contains all of your notes and settings ✓
• D. A plugin that organizes notes into categories

Why: A vault is simply a local folder that holds your Markdown notes, attachments, and configuration. Obsidian opens one vault at a time.

• A. [[Note Name]] ✓
• B. (Note Name)
• C. @Note Name
• D. #Note Name

Why: Wrapping a note title in double square brackets, [[Note Name]], creates a wiki-style internal link. Obsidian also offers autocomplete when you type these brackets.

• A. A chart of how many words you wrote each day
• B. A visual map of notes as nodes connected by the links between them ✓
• C. A timeline of when each note was created
• D. A bar chart comparing the size of each vault folder

Why: Graph View visualizes your notes as nodes and the internal links between them as edges, helping you see clusters and connections in your knowledge base.

• A. Ctrl/Cmd + Shift + P ✓
• B. Ctrl/Cmd + P
• C. Ctrl/Cmd + K
• D. Ctrl/Cmd + G

Why: Ctrl/Cmd + P opens quick switcher for jumping between notes, while Ctrl/Cmd + Shift + P opens the Command Palette, which lists every available command in the app.

• A. A folder
• B. A note (a Markdown file) ✓
• C. A workspace
• D. A plugin

Why: In Obsidian, every piece of knowledge is stored as a plain Markdown (.md) file called a note. Folders organize notes, but the note itself is the basic unit of content.

• A. [Photosynthesis](Photosynthesis)
• B. [[Photosynthesis]] ✓
• C. {{Photosynthesis}}
• D. #Photosynthesis

Why: Double square brackets, [[Note Name]], create a wikilink to another note. Obsidian resolves the name to the matching file. The # symbol creates a tag, not a link.

• A. The notes that the current note links to
• B. The notes that link to the current note ✓
• C. The most recently edited notes
• D. The file's creation date

Why: Backlinks show every other note that links to the current note. They help you discover related ideas and see how your knowledge connects in both directions.

• A. Obsidian shows an error and blocks the link
• B. Obsidian creates an unresolved link, which you can click to create the new note ✓
• C. The text is automatically deleted
• D. Obsidian converts it into a tag

Why: Obsidian allows links to notes that don't exist yet. These appear as unresolved links, and clicking one creates a new note with that name, making it easy to build out your knowledge base as you write.

• A. Put every idea into one very long note
• B. Keep each note focused on a single idea and link related notes together ✓
• C. Avoid using links so notes stay independent
• D. Name notes with random numbers so they are unique

Why: Atomic notes, each focused on one idea and connected by links, make knowledge easier to reuse, recombine, and navigate. Linking related notes builds the connected network that makes Obsidian powerful.

• A. To link notes together so they appear in the graph view
• B. To physically group files on your computer's file system ✓
• C. To automatically generate tags for each note
• D. To store the plugin settings for the vault

Why: Folders organize the actual files in your vault's directory structure on disk. Connections between notes are made with links and tags, not folders, so folders are best understood as a way to group files physically.

• A. @
• B. &
• C. # ✓
• D. %

Why: Obsidian uses the hash symbol (#) followed by a word to create a tag, such as #project or #reading. Tags let you categorize and search notes across folders.

• A. It embeds the full content of the note into the current note
• B. It creates an internal link to the note with that name ✓
• C. It deletes the note if it already exists
• D. It moves the note into the current folder

Why: Double square brackets create an internal link to another note. If the note does not exist yet, Obsidian can create it when you click the link, which makes it easy to build connections between ideas.

• A. Tags are required for notes to appear in the graph view
• B. A single note can have multiple tags but can only exist in one folder ✓
• C. Tags increase the file size of your notes significantly
• D. Folders cannot be renamed once created

Why: A note sits in exactly one folder, but it can carry many tags at once. This lets a single note belong to several overlapping categories, which folders alone cannot express.

• A. A plugin that displays a visual map of your computer's files
• B. A hub note that links together related notes on a topic to help navigation ✓
• C. A special folder that Obsidian creates automatically for backups
• D. A setting that changes the color of notes in the graph view

Why: A Map of Content is an index-style note that gathers links to related notes on a theme. It acts as an entry point into a topic and helps you navigate a growing vault without relying solely on folders.

• A. To permanently lock a note so it cannot be edited
• B. To provide a reusable structure that pre-fills content when creating new notes ✓
• C. To convert notes into PDF files automatically
• D. To sync notes across multiple devices

Why: Templates let you define a reusable structure, such as headings and properties, that is inserted whenever you create a new note, saving time and keeping notes consistent.

• A. Graph View
• B. Templates ✓
• C. Backlinks
• D. Outgoing Links

Why: The Templates core plugin must be turned on in Settings under Core plugins before you can designate a template folder and insert templates into notes.

• A. {{date}} ✓
• B. [[date]]
• C. %DATE%
• D. #date

Why: Obsidian uses double curly braces such as {{date}} as template variables, which are replaced with the current date when the template is inserted. Double square brackets create links, not dates.

• A. Automatically delete notes older than one day
• B. Create and open a note for the current date with one command ✓
• C. Track how many words you write each day
• D. Schedule reminders for tasks

Why: Daily Notes creates a dated note for the current day, optionally from a template, and lets you open it quickly, which supports journaling and daily workflows.

• A. Slides
• B. Templater or the core Templates plugin's insert command ✓
• C. Canvas
• D. Publish

Why: The core Templates plugin provides an 'Insert template' command you can bind to a hotkey, and the community plugin Templater extends this with dynamic scripting. Slides, Canvas, and Publish serve different purposes.

• A. To change the color of the app's interface only
• B. To extend Obsidian's core functionality with additional features created by third-party developers ✓
• C. To back up your vault to a cloud server automatically
• D. To convert your notes into PDF format exclusively

Why: Community plugins are developed by the Obsidian community and add new features beyond the core app, such as kanban boards, calendars, or advanced search tools.

• A. Settings > Appearance > Community Mode
• B. Settings > Community plugins, then turn off Restricted mode ✓
• C. File > Install Plugins from the top menu
• D. Help > Plugin Manager

Why: By default Obsidian runs in Restricted mode, which blocks community plugins. You must go to Settings > Community plugins and turn off Restricted mode to browse and install them.

• A. Core plugins are paid while community plugins are free
• B. Core plugins are built and maintained by the Obsidian team and ship with the app, while community plugins are made by outside developers ✓
• C. Core plugins only work on mobile devices
• D. Community plugins cannot modify the vault, while core plugins can

Why: Core plugins such as Graph view, Backlinks, and Daily notes are included and maintained by Obsidian's developers, whereas community plugins come from independent developers.

• A. Compressing large notes to save disk space
• B. Customizing the visual appearance of the interface by writing custom styling rules ✓
• C. Writing code that runs automatically when a note is opened
• D. Importing notes from other apps

Why: CSS snippets let you customize Obsidian's appearance, such as fonts, colors, and spacing, by adding custom CSS files that you can enable or disable in Settings > Appearance.

• A. Settings > Hotkeys ✓
• B. Settings > Editor > Shortcuts
• C. Settings > Files and links > Commands
• D. Settings > Advanced > Keybindings file

Why: The Hotkeys section in Settings lets you search for any command and assign, change, or remove its keyboard shortcut.

• A. Adding a tag to both notes
• B. Using a wiki-link in the format [[Note Name]] ✓
• C. Saving both notes in the same folder
• D. Pinning both notes to the sidebar

Why: Wiki-links written as [[Note Name]] create bidirectional connections between notes, and these connections are visualized as edges in the graph view. Tags and folders do not create graph links.

• A. A timeline of when each note was created
• B. A visual map of notes as nodes and their links as connecting lines ✓
• C. A list of all files sorted alphabetically
• D. The word count and reading time for each note

Why: Graph View renders your notes as nodes and the links between them as edges, helping you see clusters and relationships within your knowledge base.

• A. Outgoing links panel
• B. Backlinks panel ✓
• C. Template picker
• D. Community plugins list

Why: The Backlinks panel lists every note that contains a link pointing to the current note, which is essential for discovering connections you may not have created deliberately.

• A. Create one very large note containing everything you know
• B. Keep notes atomic, focused on a single idea, and link them to related concepts ✓
• C. Avoid linking notes so the graph stays clean
• D. Use only folders and never use links

Why: Atomic notes, each covering one idea, can be recombined and linked flexibly, which makes the graph more useful and the connections more meaningful.

• A. Obsidian shows an error and blocks the link
• B. Obsidian automatically deletes the link
• C. The link appears as unresolved, and clicking it can create a new note with that name ✓
• D. The link is converted into a tag

Why: Obsidian displays links to nonexistent notes as unresolved, and clicking one creates the note, which is a convenient way to grow your graph as you write.

• A. Obsidian stops working once a vault exceeds a certain number of notes
• B. Outdated or redundant notes can clutter search results and make it harder to find useful information ✓
• C. Obsidian automatically deletes notes that have not been opened in six months
• D. Pruning is required to keep the vault compatible with mobile devices

Why: As a vault grows, outdated, duplicate, or low-value notes accumulate and dilute search results and graph views. Regular review helps keep the knowledge base useful. Obsidian does not delete notes automatically and does not have a hard note limit.

• A. Give every note a random identifier so titles never conflict
• B. Adopt a naming convention and document it, such as using singular nouns for concept notes or dates in ISO format for journal entries ✓
• C. Use the first sentence of each note as its title without any rules
• D. Store all titles in a separate spreadsheet and never edit them

Why: A documented naming convention makes links predictable and reduces duplicate notes, which matters more as the vault grows. Random identifiers make notes hard to find and link to, and ad hoc titling leads to inconsistency.

• A. It replaces the need for tags entirely
• B. It acts as a hub note that links together related notes on a topic, helping navigation as the vault scales ✓
• C. It backs up the vault to an external server
• D. It converts notes into PDF files for sharing

Why: A Map of Content is an index-style note that collects and organizes links to related notes on a theme. As a vault grows, MOCs provide structure and entry points that make the knowledge base navigable without relying solely on search.

• A. Obsidian cannot open files that were created more than a year ago
• B. Because your notes are plain Markdown files, backups and version history protect against accidental deletion, sync conflicts, and corruption ✓
• C. Backups are needed to unlock Obsidian's premium features
• D. Version control automatically generates links between notes

Why: Obsidian stores notes as local Markdown files, so the vault is only as safe as its storage. Backups or version control such as Git protect against data loss and let you recover earlier states of your notes.

• A. Creating new notes for every idea without checking for existing ones
• B. Regularly checking for orphan notes and unresolved links, and merging duplicate notes ✓
• C. Disabling all links so the vault is easier to read
• D. Moving every note into a single folder with no subfolders or tags

Why: Orphan notes (with no incoming links) and unresolved links signal gaps or neglected content, while duplicates fragment knowledge. Routine checks using Obsidian's built-in tools help keep the vault coherent as it scales.
