  4. A. Only scanning via UDP will miss any TCP services. Since the great majority of services in use today are provided as TCP services, this would not be a useful way to conduct the scan. Setting the scan to faster timing (3 or faster), changing from a TCP connect scan to a TCP SYN scan, or limiting the number of ports tested are all valid ways to speed up a scan. Charles needs to remain aware of what those changes can mean, as a fast scan may be detected or cause greater load on a network, and scanning fewer ports may miss some ports.
