CSS uses C-style comments with /* to open and */ to close. Single-line comments (//) and other syntaxes are not valid in CSS files.

The correct CSS property for making text bold is font-weight with value bold. Option A uses the correct CSS syntax with a selector (p) and property-value pair (font-weight:bold). Options B and D incorrectly use inline style syntax with font-size or text-size, which are not properties for bold text. Option C uses the non-existent property text-size.

The default value for background-repeat is 'repeat', which means the background image repeats both horizontally and vertically. Option D correctly describes this behavior. Options A (repeat-x) and B (repeat-y) repeat only in one direction, while option C (no-repeat) prevents repetition entirely.

CSS is not limited to HTML - it can style XML documents, SVG graphics, and other markup languages. The statement claims CSS can only style HTML webpages, which is false. CSS is a general-purpose styling language.

The hex color #ffffff represents white because all three color channels (red, green, blue) are at their maximum value (FF = 255). This creates pure white light. Option D is correct. Black would be #000000 (all channels at minimum).

Two main CSS properties can hide elements: display:none removes the element completely from the layout, while visibility:hidden hides it visually but maintains its space in the layout. Options A and C are both correct. The 'view' property doesn't exist, and z-index only controls stacking order.

The CSS z-index property determines the stack order of elements that overlap. Elements with a larger z-index cover those with a smaller z-index. The display and position properties control layout and placement, while depth is not a valid CSS property.

Arsenic (As) is a Group V element (5 valence electrons). When added to silicon (Group IV, 4 valence electrons) as a dopant, it provides extra electrons, creating an n-type semiconductor. The extra electrons become majority charge carriers. Conversely, Group III elements like boron create p-type semiconductors by creating holes.

In ETL tools like DataStage, the Join component defaults to accepting two input streams (left and right links). This binary join operation merges data from two sources based on key values, making the default count equal to 2.

Gather is a de-partitioning component that collects data from multiple partitions and consolidates it into a single partition. This is the opposite of partitioning operations (like Partition by Key) that split data across partitions, making it the correct answer.

Round-robin partitioning distributes rows sequentially across partitions (row 1→partition 1, row 2→partition 2, etc.). Interleave reverses this by reading rows sequentially from each partition (partition 1 row 1, partition 2 row 1, etc.), effectively restoring the original order and undoing the round-robin effect.

Broadcast variables in distributed computing allow efficient data sharing across nodes without redundant serialization. By sending a read-only variable to all nodes once instead of with each task, broadcast reduces network overhead and enables true parallel processing of the same data across multiple workers. This increases parallelism by eliminating repeated data transfers.

The WAREHOUSELOG table in the Tivoli Data Warehouse logs detailed information about export operations, including success counts and failure reasons like ODBC errors or timeouts. This is the definitive source for export statistics.

The tacmd command is primarily used for managing UNIX Log agents in IBM Tivoli Monitoring. It can verify agent status, configuration, and connectivity. TEPS (the portal) and database status are checked through other interfaces, not tacmd.

A situation must be associated with a Navigator item to display its event icon in the Tivoli Enterprise Portal. The Navigator provides the hierarchical view where situation status indicators appear. Workspaces display data but don't control icon visibility.

The Tivoli command 'tacmd createsystemlist' is used to create or replicate Managed System Lists (MSL). Despite the name suggesting creation from scratch, this command can also duplicate an existing MSL when provided with a source list. The command creates a new MSL entry that can copy attributes from an existing one.

When TEP permissions are changed, the user must log out and log back in for the changes to take effect. This is because permissions are loaded during the login authentication process. A simple refresh or reboot won't work - the session needs to be re-established to pick up the new permission set.
