   Which of the following is the correct way to add a custom library directory so that it is searched by the dynamic linker?

   • ACreate a file in /etc/ld.so.conf.d/ containing the directory path, then run ldconfig.
   • BSet the LD_LIBRARY_PATH environment variable permanently in /etc/profile.
   • CCopy the library files directly into /lib and run ldconfig.
   • DEdit /etc/ld.so.cache directly to include the new directory.

   A junior admin asks why a program can run without the library file being in /usr/lib or /lib. Which concept explains this?

   • AThe kernel loads libraries directly from any directory.
   • BThe library is embedded in the program binary.
   • CThe program is statically linked.
   • DThe dynamic linker searches multiple configured paths, not just the default directories.

   What is the primary benefit of using shared libraries over static libraries?

   • AShared libraries are required for all programs to run on Linux.
   • BShared libraries are always faster than static libraries because they are compiled with optimizations.
   • CShared libraries are easier to write because they do not require a linker.
   • DShared libraries reduce memory usage and disk space because the same code is loaded once and used by multiple programs.

   A security audit requires you to determine whether a binary uses any libraries from a non-standard path. Which combination of commands would provide the most complete evidence?

   • Astrings /path/to/binary | grep lib
   • Breadelf -d /path/to/binary
   • Cldconfig -p | grep /path/to/binary
   • Dldd /path/to/binary and compare the resolved paths against the standard directories.
