D315 Questions and Answers Already
Graded A
What is an example of network traffic encryption?
✔✔Using TLS (Transport Layer Security) to secure data sent between a web browser and a
server.
What is the role of a security patch management system?
✔✔It helps ensure that security patches are applied to software and systems promptly to mitigate
vulnerabilities.
What is a vulnerability scan, and how does it help protect a network?
✔✔A vulnerability scan checks for known weaknesses in a system and provides
recommendations for fixing them before they can be exploited.
What is the purpose of data loss prevention (DLP) in a network?
✔✔DLP technologies monitor and prevent unauthorized sharing or access to sensitive data
within a network.

,What does a network administrator do to prevent unauthorized network access?
✔✔They implement security protocols, enforce access control measures, and monitor network
traffic for suspicious activity.
What is an example of physical network security?
✔✔Restricting access to critical hardware, such as servers and routers, by locking server rooms
and using security badges.
What is the role of a public key infrastructure (PKI) system in securing network
communications?
✔✔A PKI system manages digital certificates and keys to ensure secure communications over
untrusted networks.
What is the purpose of firewalls in preventing cyberattacks?
✔✔Firewalls monitor network traffic and enforce security policies to block unauthorized access
while allowing legitimate traffic.
What is the significance of patching in preventing cyber threats?
2
,✔✔Patching ensures that known vulnerabilities are fixed, making it harder for attackers to
exploit security gaps in software or hardware.
What is the main function of a network firewall?
✔✔To monitor and filter incoming and outgoing network traffic based on security rules.
What does a VPN (Virtual Private Network) do?
✔✔It encrypts internet traffic to protect user data and allows secure access to a private network
over the internet.
What is the role of encryption in securing communication over a network?
✔✔It converts data into a coded format to prevent unauthorized access during transmission.
What is an IDS (Intrusion Detection System)?
✔✔A system designed to detect and alert on potential security breaches or abnormal activity in a
network.
What is the difference between a hub and a switch in networking?
3
, ✔✔A hub broadcasts data to all connected devices, while a switch sends data only to the specific
device it’s intended for.
What does SSL (Secure Socket Layer) encryption provide for web communications?
✔✔It ensures that data transmitted between a web server and a browser is encrypted and secure.
What is a DDoS attack, and what is its objective?
✔✔A Distributed Denial of Service attack aims to overwhelm a system with excessive traffic to
make it unavailable to users.
What is the purpose of multi-factor authentication (MFA)?
✔✔To require multiple forms of verification (e.g., password and code) before granting access to
a system.
What is the principle of least privilege in network security?
✔✔Granting users the minimum access necessary to perform their tasks, reducing the risk of
misuse or accidental breaches.
What is a botnet in terms of network security?
