CompTIA Cyber security Analyst
(CySA+) Assessment Test Already
Passed
After running an nmap scan of a system, you receive scan data that indicates the following three
ports are open:22/TCP443/TCP1521/TCP What services commonly run on these ports?
A.SMTP, NetBIOS, MySQL
B.SSH, Microsoft DS, WINS
C.SSH, HTTPS, Oracle
D.FTP, HTTPS, MS-SQL ✔✔C. These three TCP ports are associated with SSH (22), HTTPS
(443), and Oracle databases (1521). Other ports mentioned in the potential answers are SMTP (25),
NetBIOS (137-139), MySQL (3306), WINS (1512), FTP (20 and 21), and MS-SQL (1433/1434).
Which of the following tools is best suited to querying data provided by organizations like the
American Registry for Internet Numbers (ARIN) as part of a footprinting or reconnaissance
exercise?
A.nmap
B.traceroute
C.regmon
D.whois ✔✔D. Regional Internet registries like ARIN are best queried either via their websites or
using tools like Whois. Nmap is a useful port scanning utility, traceroute is used for testing the
path packets take to a remote system, and regmon is an outdated Windows Registry tool that has
been supplanted by Process Monitor.
What type of system allows attackers to believe they have succeeded with their attack, thus
providing defenders with information about their attack methods and tools?
A.A honeypot
B.A sinkhole
C.A crackpot
D.A darknet ✔✔A. Honeypots are systems that are designed to look like attractive targets. When
they are attacked, they simulate a compromise, providing defenders with a chance to see how
attackers operate and what tools they use. DNS sinkholes provide false information to malicious
software, redirecting queries about command and control systems to allow remediation. Darknets
are segments of unused network space that are monitored to detect traffic—since legitimate traffic
should never be aimed at the darknet, this can be used to detect attacks and other unwanted traffic.
Crackpots are eccentric people—not a system you'll run into on a network.
What cybersecurity objective could be achieved by running your organization's web servers in
redundant, geographically separate datacenters?
A.Confidentiality
B.Integrity
C.Immutability
D.Availability ✔✔D. Redundant systems, particularly when run in multiple locations and with
other protections to ensure uptime, can help provide availability.
Which of the following vulnerability scanning methods will provide the most accurate detail
during a scan?
A.Black box
B.Authenticated
C.Internal view
D.External view ✔✔B. An authenticated, or credentialed, scan provides the most detailed view of
the system. Black-box assessments presum
