WGU D315 PRACTICE EXAMINATION 2026
QUESTIONS WITH ANSWERS GRADED A+
◍ Least Privilege.
Answer: An employee in HR only has access to HR-related data, not
financial records.
◍ netstat.
Answer: Users of a network have been experiencing issues. In the course of
troubleshooting, an administrator wants to view a list of network addresses
and port numbers. Which command in Linux should be used for this
purpose?
◍ Accounting.
Answer: A system logs that you accessed your email at 9:00 AM, sent two
messages, and logged out at 9:15 AM. If unusual activity occurs (e.g., login
from another country), administrators can review these logs for
investigation.
◍ ifconfig.
Answer: Similar to ipconfig, this command is used to configure the kernel
network interfaces. It is implemented at the time of booting to configure the
necessary interfaces. Once the interfaces are configured, it is used for
debugging or tuning the system. It is primarily used in Linux.
◍ Implement authentication methodologies.
Answer: A company is developing a data protection methodology in order to
improve data protection measures. What is a strategy that should be used?
◍ Attack manipulating database queries.
Answer: SQL Injection
◍ Public (cloud).
, Answer: A company uses cloud service to manage its IT resources. The
underlying hardware resources are shared by other companies as well. What
is the cloud deployment model described in the scenario?
◍ Attack involving trying many password combinations.
Answer: Dictionary Attack
◍ White hat.
Answer: A hacker acts as an information system security professional who is
hired to perform penetration testing. Which term describes the given hacker?
◍ Type 1 Hypervisor.
Answer: Runs directly on the hardware of the host machine, without needing
an underlying operating system. Allows for greater efficiency, performance,
and scalability, enabling the host to support more VMs.
◍ Attribute Based Access Control.
Answer: A healthcare worker can access patient records during their shift
but only for patients under their care.
◍ OSI layer responsible for data encryption and formatting.
Answer: Presentation Layer
◍ tftp.
Answer: This command transfers a file from either a client to a server or
from a server to a client using UDP (user datagram protocol) instead of
TCP, and so it is usually used on reliable (local) networks.
◍ Least Privilege.
Answer: Users and systems are granted only the access they need to perform
their tasks and nothing more.
◍ netstat -an.
Answer: Users of a network have been experiencing issues. In the course of
troubleshooting, an administrator wants to determine which ports have an
active connection. Which command in Windows should be used for this
purpose?
, ◍ Transport (TCP/IP model layer 3).
Answer: Transport layer (OSI layer 4)
◍ Security practice ensuring only authorized users can view sensitive info.
Answer: Access Control
◍ Integrity.
Answer: A company is implementing network security components to
ensure a higher level of data trustworthiness.
◍ route.
Answer: This command can be used to display the current route tables on a
host. It can also be used to add or remove routes. This is used by the local
host to determine where to send traffic (0.0.0.0 means the default gateway,
where the router sends things if it is not otherwise defined in the routing
table).
◍ Security design principle ensuring system fails safely.
Answer: Fail-Safe Defaults
◍ ipconfig.
Answer: Provides the user with the IP, subnet mask, and default gateway for
each network adapter by default with the /all option information, such as
MAC address, DHCP status, and lease information. The command with the
/release option can be used to release all connections and renew all adapters.
It is primarily used in Windows.
◍ Type 1 Hypervisor.
Answer: A company needs to maximize the number of virtual machines that
can run on each host. Which hypervisor should be used?
◍ Security method requiring password plus token or biometric.
Answer: Multi-Factor Authentication (MFA)
◍ Least Common Mechanism.
Answer: Avoiding shared login credentials or shared physical devices
◍ Use transport level encryption.
