Question 1Adobe Photoshop fundamentals and workspace

Which file format saves a layered document while preserving editable layers, masks, and adjustment layers?

  1. TIFF
  2. PNG
  3. PSD Correct answer.
  4. JPEG

Explanation

PSD is Photoshop's native format and stores layers, masks, adjustment layers, and other editable structure. The other listed formats flatten or discard most editing structure when saving.

Question 2Adobe Photoshop fundamentals and workspace

What does the Move tool do when the Auto-Select option is enabled in the options bar?

  1. It converts the active layer into a smart object
  2. It locks the selected layer's position
  3. It changes the active layer by clicking content on the canvas Correct answer.
  4. It selects all layers of the same color

Explanation

Auto-Select lets clicking directly on canvas content change the active layer to the one containing that content. This avoids manually picking layers in the Layers panel.

Question 3Adobe Photoshop fundamentals and workspace

What is the primary function of the Layers panel?

  1. To set the resolution of the canvas
  2. To adjust the document's color profile
  3. To manage stacking order, visibility, and properties of layers Correct answer.
  4. To record and play back actions

Explanation

The Layers panel lists layers and lets you reorder them, toggle visibility, and access layer properties and effects. Color profiles and canvas resolution are set elsewhere.

Question 4Adobe Photoshop fundamentals and workspace

Which keyboard shortcut temporarily activates the Hand tool while another tool is in use?

  1. Spacebar Correct answer.
  2. Shift
  3. Tab
  4. Alt (Option)

Explanation

Holding the spacebar temporarily switches to the Hand tool for panning, and releasing it returns to the previous tool. Modifier keys like Shift and Alt perform other functions.

Question 5Adobe Photoshop fundamentals and workspace

What does changing the zoom level to 100% display?

  1. The document at print resolution
  2. The image fit entirely within the window
  3. One image pixel per screen pixel Correct answer.
  4. A preview of the final output size

Explanation

At 100% zoom, each image pixel maps to one screen pixel, showing actual pixel detail. Fit Screen is a separate command that scales the view to the window.

Question 6Adobe Photoshop fundamentals and workspace

Which panel is used to record a sequence of steps and replay them later?

  1. Properties
  2. Adjustments
  3. Actions Correct answer.
  4. History

Explanation

The Actions panel records commands and plays them back, enabling automation of repetitive tasks. The History panel tracks past states but does not record replayable sequences.

Question 7Adobe Photoshop fundamentals and workspace

What is the purpose of the History panel?

  1. To manage installed fonts
  2. To list and revert to previous document states Correct answer.
  3. To save multiple versions of the file
  4. To store color swatches

Explanation

The History panel records recent states of the document and lets you step back to an earlier state. It is a working-session tool rather than a file versioning system.

Question 8Adobe Photoshop fundamentals and workspace

Which command opens the dialog for setting image dimensions and resolution?

  1. Image Size Correct answer.
  2. Document Setup
  3. Reveal All
  4. Canvas Size

Explanation

Image Size controls the pixel dimensions and resolution of the image. Canvas Size changes the workspace around the image without resampling pixels.

Question 9Adobe Photoshop fundamentals and workspace

A designer needs to keep a layer's content editable when applying a filter. What should they do first?

  1. Lock the layer
  2. Rasterize the layer
  3. Merge the layer down
  4. Convert the layer to a smart object Correct answer.

Explanation

Smart objects store the original content and apply filters as editable smart filters, so changes can be revisited. Rasterizing or merging destroys that flexibility.

Question 10Adobe Photoshop fundamentals and workspace

Why might a designer choose the Pen tool over the Lasso tool for a precise cutout?

  1. It creates editable vector paths with smooth curves Correct answer.
  2. It automatically detects subject edges
  3. It samples colors from the image
  4. It applies feathering to the selection

Explanation

The Pen tool builds vector paths that can be adjusted point by point and converted to selections, giving precise control over curves. The Lasso tool is freehand and less precise for smooth edges.

Question 11Adobe Photoshop fundamentals and workspace

What happens when you hold Alt (Option) and drag a layer in the Layers panel?

  1. A duplicate of the layer is created Correct answer.
  2. The layer is merged with the one below
  3. The layer's visibility is toggled
  4. The layer is deleted

Explanation

Alt-dragging a layer duplicates it, which is a quick way to copy content or settings. Dragging without the modifier simply reorders the layer.

Question 12Adobe Photoshop fundamentals and workspace

Which workspace element lets you quickly switch among commonly used panels for a task?

  1. The status bar
  2. The toolbar
  3. The tabbed document window
  4. The workspace switcher in the options bar Correct answer.

Explanation

Photoshop provides workspace presets such as Essentials and Photography, selectable from the workspace switcher, that arrange panels for a given task. This helps tailor the interface.

Question 13Adobe Photoshop fundamentals and workspace

What is the effect of setting a layer's blend mode to Multiply?

  1. It inverts the layer's colors
  2. It removes the layer from the composite
  3. It lightens the result by adding values
  4. It darkens the result by multiplying pixel values Correct answer.

Explanation

Multiply darkens by multiplying the base and blend colors, so white becomes transparent and darker values darken the result. Screen is the opposite, lightening the image.

Question 14Adobe Photoshop fundamentals and workspace

A user wants to undo the last action but the History panel shows the state is unavailable. What is the most likely cause?

  1. The document was saved as JPEG
  2. The tool is set to a low opacity
  3. The History States limit was exceeded Correct answer.
  4. The layer is locked

Explanation

Photoshop keeps a limited number of history states, and older states are discarded once the limit is reached. Raising the History States preference allows deeper undo history.

Question 15Adobe Photoshop fundamentals and workspace

Which method creates a non-destructive adjustment that can be edited later?

  1. An adjustment layer from the Layers panel Correct answer.
  2. Image > Adjustments > Levels
  3. The Dodge tool
  4. A destructive filter applied to a raster layer

Explanation

Adjustment layers store the adjustment settings as a separate layer and can be re-edited or masked at any time. The Image > Adjustments menu applies changes directly to pixels.

Question 16Adobe Photoshop fundamentals and workspace

What does the Quick Select tool do?

  1. It paints a selection based on similar color and texture Correct answer.
  2. It creates a vector mask
  3. It replaces the background color
  4. It selects the entire canvas

Explanation

Quick Select works like a brush that expands a selection over areas of similar color and texture. It is often refined with the Select and Mask workspace.

Question 17Adobe Photoshop fundamentals and workspace

Which preference setting controls how many recent documents appear in the File > Open Recent menu?

  1. File Handling Correct answer.
  2. Interface
  3. Scratch Disks
  4. Performance

Explanation

The File Handling preferences include the option to set how many recent files are listed. This helps users quickly reopen frequently used documents.

Question 18Adobe Photoshop fundamentals and workspace

A user cannot find a panel that was closed. What is the most reliable way to reopen it?

  1. Restart the application
  2. Reset all preferences
  3. Use the Window menu and select the panel name Correct answer.
  4. Press Ctrl/Cmd+S

Explanation

The Window menu lists available panels and toggles their visibility, so closed panels can be reopened from there. This avoids losing other settings.

Question 19Adobe Photoshop fundamentals and workspace

What is the purpose of the tabbed document window arrangement?

  1. To display the toolbar
  2. To split a single image into tiles
  3. To show multiple open documents as tabs for quick switching Correct answer.
  4. To compare color profiles

Explanation

Opening multiple images as tabs keeps the workspace organized and allows quick switching among documents. Documents can also be floated if preferred.

Question 20Adobe Photoshop fundamentals and workspace

Why does the Navigator panel help when working at high zoom levels?

  1. It records actions
  2. It lists layer styles
  3. It displays a thumbnail with a movable view box Correct answer.
  4. It shows the color picker

Explanation

The Navigator panel shows a thumbnail of the whole image with a box indicating the current view, letting users pan quickly at high zoom. It is a navigation aid, not an editing tool.

Question 21Adobe Photoshop fundamentals and workspace

A user wants a layer's effect to appear only over a specific area without deleting its pixels. What is the best approach?

  1. Add a layer mask and paint black over the area to hide Correct answer.
  2. Change the blend mode
  3. Apply a filter to the layer
  4. Lower the layer opacity

Explanation

A layer mask hides portions of a layer non-destructively; painting black conceals and white reveals. The underlying pixels remain intact and can be restored.

Question 22Adobe Photoshop fundamentals and workspace

What is the difference between Image Size and Canvas Size when resampling is disabled?

  1. Image Size changes pixel dimensions; Canvas Size changes the document's working area Correct answer.
  2. Canvas Size resamples pixels; Image Size does not
  3. Both change pixel dimensions identically
  4. Image Size changes the color mode

Explanation

With resampling off, Image Size adjusts print size and resolution without changing pixel count, while Canvas Size adds or removes canvas around the existing pixels. They serve different structural purposes.

Question 23Adobe Photoshop fundamentals and workspace

A designer needs the same adjustment applied to several layers at once. What is the most efficient non-destructive method?

  1. Duplicate the document for each layer
  2. Rasterize all layers and apply the adjustment
  3. Apply the adjustment to each layer individually
  4. Group the layers and apply an adjustment layer to the group Correct answer.

Explanation

An adjustment layer placed above a group affects the group as a whole, and grouping can be clipped so the adjustment applies only to those layers. This avoids repetitive edits and keeps the workflow non-destructive.

Question 24Adobe Photoshop fundamentals and workspace

Why might a user choose a smart filter over a standard filter on a raster layer?

  1. Smart filters bypass color management
  2. Smart filters can be masked and re-edited after application Correct answer.
  3. Smart filters always produce sharper results
  4. Smart filters reduce file size

Explanation

Smart filters remain editable and can be masked and reordered, preserving flexibility. Standard filters permanently alter pixel data on a raster layer.

Question 25Adobe Photoshop fundamentals and workspace

A user reports that their brush strokes are being applied to the wrong layer. What is the most likely explanation?

  1. The document color mode is CMYK
  2. The zoom level is set to 100%
  3. The brush opacity is too low
  4. The active layer in the Layers panel is not the intended layer Correct answer.

Explanation

Painting affects the currently active layer, so strokes appear on whichever layer is selected in the Layers panel. Checking the active layer resolves most such issues.

Question 26Adobe Photoshop fundamentals and workspace

Which panel provides controls for creating and editing vector shapes and paths?

  1. Swatches
  2. Paths Correct answer.
  3. Channels
  4. Brush

Explanation

The Paths panel stores and manages saved vector paths, including those created with the Pen tool and shape tools. It allows you to load, save, and convert paths into selections or masks.

Question 27Adobe Photoshop fundamentals and workspace

What is the primary function of the Layers panel in Photoshop?

  1. To manage the stacking order and visibility of image elements Correct answer.
  2. To record and replay a sequence of editing steps
  3. To convert color images to grayscale
  4. To adjust the color balance of the entire image

Explanation

The Layers panel lists all layers, groups, and effects, allowing you to reorder, hide, lock, and apply blending modes or masks. It is central to non-destructive compositing.

Question 28Adobe Photoshop fundamentals and workspace

Which tool allows you to sample a color from an open image and set it as the foreground color?

  1. Magic Wand
  2. Eyedropper Correct answer.
  3. Gradient
  4. Color Sampler

Explanation

The Eyedropper tool picks up color values from the image and assigns them to the foreground color swatch. You can Alt-drag (Option-drag) to sample a color into the background swatch.

Question 29Adobe Photoshop fundamentals and workspace

What does the Zoom tool do when you click on the image?

  1. It rotates the canvas to the clicked angle
  2. It magnifies the view around the clicked point Correct answer.
  3. It reduces the view around the clicked point
  4. It changes the image resolution to match the zoom level

Explanation

Clicking with the Zoom tool enlarges the display around the clicked area. Alt-clicking (Option-clicking) with the Zoom tool reduces the view.

Question 30Adobe Photoshop fundamentals and workspace

A user wants to change the unit of measurement displayed on the rulers. Where can this be set?

  1. In the Layers panel menu
  2. In the Preferences dialog under Units & Rulers Correct answer.
  3. In the Canvas Size dialog
  4. In the Image Size dialog

Explanation

Ruler units are configured in Edit > Preferences > Units & Rulers (Windows) or Photoshop > Preferences > Units & Rulers (macOS). This setting also affects other measurement fields in the interface.

Question 31Adobe Photoshop fundamentals and workspace

Which keyboard shortcut temporarily activates the Hand tool while another tool is selected?

  1. Spacebar Correct answer.
  2. H
  3. Z
  4. V

Explanation

Holding down the Spacebar temporarily switches to the Hand tool, allowing you to pan the image. Releasing the Spacebar returns to the previously active tool.

Question 32Adobe Photoshop fundamentals and workspace

What is the purpose of the Application Frame in Photoshop (macOS)?

  1. It automatically saves the document at set intervals
  2. It displays a full-screen preview without any panels
  3. It locks the position of all panels to prevent accidental movement
  4. It groups all document windows and panels into a single resizable window Correct answer.

Explanation

The Application Frame consolidates the document windows, menu bar, and panels into one window, which helps organize the workspace on macOS. It can be toggled from the Window menu.

Question 33Adobe Photoshop fundamentals and workspace

A designer wants to save the current panel arrangement as a custom workspace. Which command should they use?

  1. Edit > Presets > Export/Import Presets
  2. View > Screen Mode
  3. Window > Workspace > New Workspace Correct answer.
  4. File > Save As

Explanation

The New Workspace command in the Window > Workspace submenu saves the current panel layout, keyboard shortcuts, and menus as a named workspace. This workspace can be recalled later from the same submenu.

Question 34Adobe Photoshop fundamentals and workspace

Which feature allows you to align and distribute selected layers precisely?

  1. The Layers panel filter
  2. The History panel
  3. The Character panel
  4. The Move tool options bar Correct answer.

Explanation

With the Move tool active, the options bar displays alignment and distribution buttons that act on selected layers. These controls help position multiple layers evenly.

Question 35Adobe Photoshop fundamentals and workspace

What does the Tab key do when pressed in the Photoshop workspace?

  1. It cycles through open documents
  2. It hides or shows all panels Correct answer.
  3. It toggles the rulers on and off
  4. It switches to the next tool in the toolbox

Explanation

Pressing Tab toggles the visibility of all panels, giving a cleaner view of the image. Shift+Tab hides or shows only the panels on the right side.

Question 36Adobe Photoshop fundamentals and workspace

A user wants to view two open documents side by side at the same time. Which arrangement should they choose?

  1. Window > Arrange > 2-up Vertical Correct answer.
  2. Window > Arrange > Consolidate All to Tabs
  3. Window > Arrange > Match Zoom
  4. Window > Arrange > Float All in Windows

Explanation

The 2-up Vertical arrangement displays two documents side by side, each in its own pane. Other arrangements like 2-up Horizontal or 3-up are also available.

Question 37Adobe Photoshop fundamentals and workspace

Which panel allows you to adjust the color and density of a gradient fill on a shape layer?

  1. Adjustments
  2. Info
  3. Properties Correct answer.
  4. Actions

Explanation

The Properties panel provides controls for the selected object, such as a shape layer's fill, stroke, and gradient settings. It centralizes adjustments for non-destructive elements.

Question 38Adobe Photoshop fundamentals and workspace

A designer needs to work with a document that uses a color profile not currently set as the default. Where can they enable a warning that appears when opening such a document?

  1. Image > Mode
  2. Filter > Blur
  3. Layer > Layer Style
  4. Edit > Color Settings Correct answer.

Explanation

The Color Settings dialog includes options to enable profile mismatch warnings when opening or pasting images. This helps maintain color consistency across documents.

Question 39Adobe Photoshop fundamentals and workspace

What is the purpose of the Lock Workspace feature in the Window > Workspace menu?

  1. It prevents the document from being saved
  2. It disables all keyboard shortcuts
  3. It prevents panels from being accidentally moved or resized Correct answer.
  4. It locks all layers in the document

Explanation

Locking a workspace freezes the current panel positions and sizes, so they cannot be changed inadvertently. This is useful in shared or presentation environments.

Question 40Adobe Photoshop fundamentals and workspace

A user wants to quickly cycle through the tools hidden under a tool group in the toolbox. What should they do?

  1. Right-click the tool icon and choose from the list
  2. Double-click the tool icon
  3. Hold Shift and press the tool's shortcut key repeatedly
  4. Press the tool's shortcut key repeatedly Correct answer.

Explanation

Pressing the same shortcut key repeatedly cycles through the tools that share that shortcut. For example, pressing B repeatedly cycles through the Brush, Pencil, and Color Replacement tools.

Question 41Document setup, layers, and selections

Which color mode should you choose for a document that will be printed on a commercial press?

  1. RGB
  2. Grayscale
  3. CMYK Correct answer.
  4. Indexed Color

Explanation

Commercial printing presses use cyan, magenta, yellow, and black inks, so CMYK is the appropriate color mode for print-destined documents. RGB is intended for screen display, while Grayscale and Indexed Color are limited modes not suited to full-color press work.

Question 42Document setup, layers, and selections

You need a document whose printed size is 8 inches by 10 inches at 300 ppi. Which setting combination in the New Document dialog produces that result?

  1. Width 8 in, Height 10 in, Resolution 72 ppi
  2. Width 8 in, Height 10 in, Resolution 300 ppi Correct answer.
  3. Width 2400 px, Height 3000 px, Resolution 72 ppi
  4. Width 8 cm, Height 10 cm, Resolution 300 ppi

Explanation

Document dimensions are set in the Width and Height fields with an explicit unit, and Resolution sets the pixel density. Entering 8 in by 10 in at 300 ppi yields a document that prints at those physical dimensions with 300 pixels per inch. Using 72 ppi or centimeter units changes either the pixel dimensions or the physical size.

Question 43Document setup, layers, and selections

What is the default background of a new document when the Background Contents menu is set to White?

  1. A single locked layer filled with white Correct answer.
  2. A transparent layer named Layer 1
  3. A white layer that is automatically set to 50% opacity
  4. A background layer filled with the current background color

Explanation

Choosing White creates a Background layer that is locked and filled with white pixels. A transparent document instead creates a regular layer named Layer 1, and choosing Background Color fills the background layer with the current background swatch.

Question 44Document setup, layers, and selections

Which tool should you use to draw a freeform selection outline around an irregular object?

  1. Lasso Correct answer.
  2. Elliptical Marquee
  3. Rectangular Marquee
  4. Magic Wand

Explanation

The Lasso tool lets you draw a freehand outline, which is useful for irregular shapes. The marquee tools create only fixed geometric selections, and the Magic Wand selects by color similarity rather than by drawn outline.

Question 45Document setup, layers, and selections

Which keyboard shortcut adds to an existing selection while using a marquee or lasso tool?

  1. Spacebar
  2. Shift Correct answer.
  3. Ctrl (Windows) or Command (Mac)
  4. Alt (Windows) or Option (Mac)

Explanation

Holding Shift while drawing a selection adds the new area to the existing selection. Alt/Option subtracts from the selection, and holding both Shift and Alt/Option intersects the selections.

Question 46Document setup, layers, and selections

Where do you change the feather radius of an active selection after it has been created?

  1. Image > Adjustments > Feather
  2. Filter > Blur > Feather
  3. Layer > Layer Style > Feather
  4. Select > Modify > Feather Correct answer.

Explanation

Feather is applied to a selection through Select > Modify > Feather, which softens the selection edge by the specified radius. It is a selection modification, not an image adjustment, filter, or layer style.

Question 47Document setup, layers, and selections

What does the Refine Edge command primarily help you do?

  1. Improve the quality of difficult selection edges such as hair or fur Correct answer.
  2. Convert a selection into a vector path
  3. Adjust the tonal range of a selection
  4. Change the color mode of the document

Explanation

Refine Edge provides controls for smoothing, feathering, and adjusting the contrast and shift of selection edges, which is especially useful for fine details like hair. It does not alter tones, create paths, or change color modes.

Question 48Document setup, layers, and selections

Which layer type preserves image detail while allowing non-destructive tonal and color adjustments?

  1. Adjustment layer Correct answer.
  2. Shape layer
  3. Smart Object layer
  4. Background layer

Explanation

Adjustment layers apply corrections such as Levels or Hue/Saturation as separate layers, leaving the underlying pixels unchanged and editable. Background layers hold pixels directly, while shape layers contain vector fills and strokes.

Question 49Document setup, layers, and selections

You want to reposition a selected area on the same layer without leaving a hole. Which command should you use?

  1. Edit > Content-Aware Fill
  2. Edit > Free Transform Correct answer.
  3. Edit > Cut, then Edit > Paste
  4. Select > Transform Selection

Explanation

Free Transform moves the selected pixels within the layer and fills the vacated area with surrounding content. Cutting and pasting moves the pixels to a new layer and leaves a transparent gap, while Transform Selection only changes the selection outline.

Question 50Document setup, layers, and selections

Which option in the New Document dialog lets you start from a saved set of dimensions, resolution, and color mode?

  1. Artboards
  2. Preset Correct answer.
  3. Pixel Aspect Ratio
  4. Color Profile

Explanation

The Preset menu offers preconfigured document settings such as Print, Web, and Photo sizes. Artboards control document layout, Color Profile sets the working space, and Pixel Aspect Ratio adjusts pixel geometry for video.
