/etc/services on my CentOS machine goes up to 49000. Reserved ports are less than 1024.

Well known and reserved ports are two different things. Well known ports only need a registration with IANA. Reserved ports, on *nixes, requires root for a deamon to bind to the port.

Which directory in the FHS stores programs and configuration information that can only be executed and modified by the root user
dlinn [17]

Answer: /sbin

Explanation:

In Linux, FHS describes the directory content and the way in which Operating System files are displayed to the user.

/sbin is a directory that contains executable programs. s/bin is the short form of system binaries. System binaries require root rights to perform specific tasks. /sbin contains binaries that are crucial to boot the system and also to recover and restore the system. /bin directory also contains the commands to boot the system but the main difference between both is that /sbin programs can only be executed by the root user. Examples are fdisk, fsck, root,halt, init, grub, ifconfig.
