LFCS Question #217: Real Exam Question with Answer & Explanation

Question

What is the syntax error in the following simple Puppet configuration file? class test_class { file { "/tmp/test.txt": mode => 600, owner => root, group => root } } # Define the node node testclient { isa test_class }

Options

• AComments begin with // character and not a #.
• BThe colon (:) after /tmp/test.txt should be a semicolon (;).
• Cclass, node and file sections require a semicolon (;) at the end of their definitions.
• Disa should be include.

Explanation

The Puppet configuration has a syntax error because it uses isa to include a class in a node definition, where the correct keyword should be include.

Common mistakes.

• A. Comments in Puppet correctly begin with a hash symbol (#), as shown in the example, so this is not a syntax error.
• B. In Puppet resource declarations, a colon (:) correctly separates the resource title from its attribute list, such as "/tmp/test.txt":, so a semicolon (;) would be incorrect here.
• C. Class, node, and resource definitions in Puppet use curly braces ({}) for block delimitation and do not require semicolons (;) at the end of their definitions.
