WGU D482 FINAL - TASK 1 | SECURE
NETWORK DESIGN | 2026 UPDATE WITH
COMPLETE SOLUTION ALREADY GRADED A+
An ad hoc network design team has just finished a presentation on the latest
updates to the organization's
network infrastructure. The team ensured that plenty of redundancy has
been built in and bottlenecks
have been eliminated.
Which security objective has the team bolstered through these
improvements? - ANSWERS-Availability
A company has recently implemented a new email encryption system that
uses public key infrastructure
(PKI). The company is now requiring all employees to sign and encrypt
internal communication. An
employee wants to send a digitally signed message to the IT director.
What does the IT director use to decode the employee's signature under the
new system? - ANSWERS-The employee's public key
An administrator at a small office is tasked with supporting a new time clock
that has been installed on the
network. The outsourced company managing the time clock states that the
connection protocol it uses
with the clock is encrypted, but it needs to allow incoming connections from
the Internet.
Which action should allow the outsourced company to securely manage the
time clock with a minimal
amount of configuration effort? - ANSWERS-Setting up a port forward on the
firewall from the outsourced company to the
,time clock
A small nonprofit company has received several legacy wireless access
points (APs) as a donation. The
security administrator discovers that the encryption protocol the devices use
is not very secure. The encryption key can be discovered by a malicious
hacker in only a few minutes. After discussions with other
security professionals, the administrator learns the APs can implement a key
protocol that can change the
encryption key every few seconds and provide a per-packet verification at
each side of the
communication.
A laptop has been stolen, and the data has been seen for sale on the
darknet. Which process could have protected the confidentiality of the data?
- ANSWERS-Hard Drive Encryption
Classify each attack method in relation to its direct impact on the CIA triad. -
ANSWERS-Key Logger: Confidentiality
DNS Poisoning: Integrity
Covert Channels: Confidentiality
DDoS: Availability
A security administrator has configured a small keysize to protect the VPN.
Which security objective does this affect? - ANSWERS-Confidentiality
A laptop has been stolen, and the data has been seen for sale on the
darknet.
Which process could have protected the confidentiality of the data? -
ANSWERS-Hard Drive encryption
, When browsing to a financial website, a user receives an error on the
browser that points to the certificate
on the website. The user reviews the certificate and maps it to a known
certificate authority.
Why did the user need to perform these actions? - ANSWERS-To establish a
trust relationship
A team of scientists is working on a secure project. The network
administrator needs to configure a
network for the team that is not routable from the Internet. A firewall is
protecting the scientists' network
and is using network address translation (NAT) to translate the internal IP
addresses to public IP
addresses.
Which IP address should the network administrator configure on the inside
interface of the firewall? - ANSWERS-10.14.15.16
Which security measure is the key protocol implemented to protect? -
ANSWERS-Integrity of the key
A recently terminated employee from accounting used several widely
available programs in an amateur
attempt to exploit a company's database.
Which term describes the terminated employee? - ANSWERS-Script kiddies
An organization has recently undergone a period of growth, both in terms of
business operations and
personnel. The network infrastructure has kept pace, growing to
accommodate the new size and
structure. Mapping and auditing of the expanded network needs to be done.
One of the first findings is
