Question 1
What is the primary purpose of a Web Application Firewall (WAF)?
Answer: To protect web applications from common attacks such as SQL
injection, cross-site scripting (XSS), and other OWASP Top 10 vulnerabilities
by inspecting HTTP/HTTPS traffic and filtering malicious requests.
Rationale: Unlike traditional network firewalls that operate at lower
network layers, a WAF specifically focuses on application-layer traffic (Layer
7), analyzing HTTP requests and responses to detect and block web-based
attacks .
,Question 2
Which of the following is NOT a typical deployment mode for a
Barracuda WAF?
A) One-Arm Proxy
B) Two-Arm Proxy (Inline)
C) Transparent Bridge
D) VPN Gateway
Answer: D) VPN Gateway
Rationale: Common Barracuda WAF deployment modes include One-Arm
Proxy, Two-Arm Proxy (Inline), and Transparent Bridge. VPN Gateway is not
a standard WAF deployment mode—it is associated with firewall products
like Barracuda NextGen Firewall .
Question 3
In a One-Arm Proxy deployment, which of the following statements is
true?
Answer: Backend servers could potentially be reached directly, bypassing
the WAF.
Rationale: In One-Arm Proxy mode, the WAF uses a WAN and LAN
interface and traffic is directed to the WAF via routing. Because the WAF is
not inline, it is possible for clients to bypass it by connecting directly to the
backend servers if network routing allows it .
Question 4
What is WAF's passive mode?
,Answer: A mode where the WAF logs traffic that triggers security violations
but does not block it.
Rationale: Passive mode is used for testing and tuning purposes. The WAF
analyzes traffic and logs security violations, allowing administrators to
assess the impact of security policies before enforcing them in blocking
mode .
Question 5
In WAF passive mode, what happens to traffic that triggers security
violations?
Answer: The traffic is logged but allowed through.
Rationale: Passive mode provides visibility without disruption. The WAF
identifies and logs potentially malicious traffic, but does not block it,
making it ideal for initial deployment and policy tuning phases .
Question 6
Which of the following is a prerequisite knowledge area for the
WAF01 exam?
A) Cloud computing architecture
B) OWASP Top 10 attack vectors
C) Windows Server administration
D) Database design
Answer: B) OWASP Top 10 attack vectors
, Rationale: The course prerequisites include knowledge of web application
technologies and OWASP Top 10 attacks, as understanding these threats is
fundamental to effectively configuring and managing a WAF .
Question 7
What programming language knowledge is recommended as a plus
for WAF administration?
Answer: HTML, Java, or SQL
Rationale: Familiarity with these languages helps administrators
understand web application behavior and security vulnerabilities. SQL
knowledge is particularly valuable for understanding SQL injection attacks,
while HTML and Java help in understanding web application structure .
Question 8
Which Barracuda WAF course code covers the Foundation
certification?
Answer: WAF01
Rationale: The Barracuda Web Application Firewall Foundation certification
is identified by the course code WAF01, with the exam designated as
WAF01-05 .
Question 9
What are the two primary certification levels offered by Barracuda for
WAF?
Answer: Engineer and Expert
