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take to a remote system, and regmon is an outdated Windows Registry tool that has been supplanted by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 presume no knowledge of a system and would not have credentials or an
agent to work with on the system. Internal views typically provide more detail than external views, but
neither provides the same level of detail that credentials can allow.
In early 2017, a flaw was discovered in the Chakra JavaScript scripting engine in Microsoft's Edge
browser that could allow remote execution or denial of service via a specifically crafted website. The
CVSS 3.0 score for this reads
