Final answer:
Database administrators typically work in environments where they spend time sitting, use telephone and electronic mail for communication, and operate in indoors, environmentally controlled conditions. Extremely bright or inadequate lighting and very hot or cold temperatures are less common.
Step-by-step explanation:
When considering the common work contexts for database administrators according to the O*Net database, certain environmental and communication factors stand out. Typically, database administrators will likely spend time sitting as their job often requires hours at a desk in front of a computer screen. To maintain efficiency and connectivity, they frequently use telephone and electronic mail contact with others to collaborate and manage systems. Although they may sometimes face extremely bright or inadequate lighting, it is much less common than the other contexts mentioned. The temperature setting is usually indoors, environmentally controlled which helps promote a stable working condition, while extreme temperatures like very hot or cold temperatures are uncommon in typical office environments where database administration is done.
