D315 WGU Questions and Answers
Already Passed
What is the difference between a static and dynamic IP address?
✔✔A static IP address is fixed and does not change, while a dynamic IP address is assigned by a
DHCP server and may change periodically
What is the purpose of two-factor authentication (2FA)?
✔✔To enhance security by requiring two forms of identification to verify a user’s identity
What is the difference between a virus and a Trojan horse?
✔✔A virus attaches itself to programs and spreads when executed, while a Trojan horse
disguises itself as legitimate software to deceive users
What is the role of an SSL/TLS handshake in secure communication?
✔✔To establish a secure connection between a client and a server by agreeing on encryption
algorithms and exchanging keys
1
,What is the purpose of a packet-sniffing tool in network security?
✔✔To capture and analyze network traffic, helping detect security breaches or troubleshoot
network issues
What is the concept of "defense in depth" in network security?
✔✔A layered security strategy that uses multiple defenses to protect data and networks from
attacks
What is a vulnerability scanner used for?
✔✔To identify security weaknesses and vulnerabilities in a system or network that could be
exploited by attackers
What is the function of a network access control (NAC) system?
✔✔To enforce security policies and control which devices can connect to a network
What is a key benefit of using an IDS over an IPS?
✔✔An IDS detects potential threats and alerts administrators, while an IPS actively blocks and
prevents attacks in real-time
2
, What is the primary function of encryption in network communications?
✔✔To secure data by converting it into an unreadable format, only decryptable by authorized
users
What does the acronym VPN stand for, and what is its purpose?
✔✔Virtual Private Network – To create a secure, private connection over a public network
What is an IDS (Intrusion Detection System)?
✔✔A system designed to monitor network traffic for suspicious activity and potential threats
What does a router do in a network?
✔✔It routes data packets between different networks, helping them communicate with each
other
What is the role of DNS (Domain Name System) in networking?
✔✔To translate domain names (like www.example.com) into IP addresses for network devices
What is the definition of a botnet?
