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 ✔Correct Answer-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 ✔Correct Answer-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for testing the path packets take to a remote system, and regmon is an outdated Windows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 ✔Correct Answer-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 ✔Correct Answer-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 ✔Correct Answer-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
CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H
What is the attack vector and the impact to integrity based on this rating?
A.System, 9, 8
B.Browser, High
C.Network, High
D.None, High ✔Correct Answer-C. When reading the CVSS 3.0 score, AV is the attack vector.
Here, N means network. Confidentiality (C), Integrity (I), and Availability (A) are listed at the end
of the listing, and all three are rated as High in this CVSS rating.
Alice is a security engineer tasked with performing vulnerability scans for her organization. She
encounters a false positive error in one of her scans. What should she do about this?
A.Verify that it is a false positive, and then document the exception
B.Implement a workaround
C.Update the vulnerability scanner
