Question #1
What does the push function return when it adds one or more elements to the end of an array?
Correct answer: C
Explanation
push appends the list to the array and returns the new element count. It does not return the added value or an index; the index of the last element is available through $#array.

Question #2
The file report.pl contains valid Perl syntax. Its first statement is: print "Starting\n"; A developer runs the following command: perl -c report.pl What is the result?
Correct answer: A
Explanation
The -c switch compiles the script and checks syntax without running the main program, so the print statement never executes. Perl reports report.pl syntax OK when compilation succeeds.

Question #3
Consider the following code: package Counter; sub new { my $class = shift; my $self = { count => 0 }; return bless $self, $class; } package main; my $c = Counter->new; print ref($c); What is the output?
Correct answer: A
Explanation
bless attaches the package name passed in $class to the hash reference, and Counter->new passes "Counter". The ref function then returns that class name. HASH would be returned only for an unblessed hash reference, and the Counter=HASH(...) form appears when the object itself is printed.

Question #4
Consider the following code: my $n = 7; my $d = 2; print(($n / $d) . " " . ($n % $d) . " " . ($n ** $d) . "\n"); What is the output?
Correct answer: B
Explanation
Perl division is floating point, so 7 / 2 is 3.5. The % operator gives the remainder 1, and ** is exponentiation, so 7 ** 2 is 49. Candidates who expect integer division or treat ** as multiplication choose the wrong values.

Question #5
A developer is running a script in the Perl debugger and is stopped at a line that calls the subroutine calc(). The developer wants to execute that line as a single step without stepping into calc(). Which debugger command should be entered?
Correct answer: B
Explanation
The n command executes the next statement and steps over any subroutine call. The s command steps into the subroutine, c continues to the next breakpoint or the end of the program, and r runs until the current subroutine returns.

Question #6
A script is started with the following command: perl backup.pl -v /home What value does $ARGV[0] contain inside the script?
Correct answer: A
Explanation
@ARGV holds only the arguments that follow the script name, starting at index 0. The script name is available in $0, and the interpreter name is not stored in @ARGV.

Question #7
Which statement replaces every occurrence of the string cat in $text with the string dog?
Correct answer: B
Explanation
The g modifier makes the substitution global. Without it only the first match is replaced, and i only makes matching case-insensitive. The tr operator translates single characters (c to d, a to o, t to g) rather than replacing whole strings.

Question #9
Consider the following Perl code: my $n = 5; my $total = 0; $total += $n while $n-- > 0; print $total; What is the output?
Correct answer: B
Explanation
With a statement modifier, the condition is tested first, and $n-- > 0 decrements $n as a side effect before the body runs. The body therefore adds 4, 3, 2, 1 and 0, giving 10. The value 15 comes from assuming the body sees the value before the decrement.

Question #10
Which expression is true only when /data/log.txt exists and contains at least one byte?
Correct answer: C
Explanation
The -s file test returns the size in bytes, which is true only when the file exists and is not empty. The -e test is true for an empty file as well, and -z is true for an existing file of zero size. The -d test checks for a directory.
