Certified Ethical Hacker (CEH) v13 312-50v13 — Question 306

During a quarterly security audit at a financial services company in Charlotte, North Carolina, you are tasked with reviewing exposed services on legacy servers inherited from a third-party vendor. While scanning, you discover that TCP port 1434 is open on a database node that is not listed in the company’s active inventory. The IT team has no records explaining why this service is running, and you are asked to determine whether the exposure of this port could indicate an unnecessary database-related risk. Based on standardized port assignments, which service is most likely running on this port and requires further review?
