What is the Mark of the Root Domain in the FQDN?
Correct Answer:

Explanation
The mark of the root domain in the FQDN is represented by a single dot '.' This dot signifies the top-level domain in the FQDN hierarchy and separates the root domain from the rest of the domain name components.
What is the meaning of ''QR'' sub-field in the Header field of the DNS Message ?
Correct Answer:
A
Explanation
The QR field in the DNS message header is a single bit that distinguishes between two message types. When QR is set to 0, the message is a query from a client requesting DNS information. When QR is set to 1, the message is a response from a DNS server providing the answer. This field is fundamental to how DNS communication works and is essential knowledge for anyone designing or implementing DNS systems.
What is the granted Resulted access to the MIB Data Object for the following combinations ?
The Access Object has ''Read-write'' Access Type assigned to it
The User has ''Read-write'' Access Type assigned to him
The Result will be :
Correct Answer:
A
Explanation
When both the Access Object and the user have 'Read-write' access type assigned to them, the resulted access to the MIB Data Object will also be read-write. This grants the user the permission to both read and write data to the MIB Data Object, allowing for full control and manipulation of the data.

What is the Main Role of the Local DNS Server in the Root hints Recursion Method?
Correct Answer:
A, B
Explanation
The main role of the local DNS server in the root hints recursion method is to handle the recursion process by querying all DNS levels to find the final resolution for the user's query. It acts as an intermediary between the end user's query and the authoritative DNS servers to resolve the domain name.
The local DNS server does not have direct communication with the end user PC that sent the query in the root hints recursion method. Instead, it communicates with other DNS servers in the hierarchy to resolve the query and provide the final resolution back to the user.
How can we update the oldest version of the big3d agent on the F5 LTM BIGIP Systems?
Correct Answer:
A
Explanation
Running the big3d_install script on the F5 GTM System that communicates with the LTM System is the correct choice because the big3d agent is specifically designed for communication between GTM and LTM systems. By running the big3d_install script, the oldest version of the big3d agent on the LTM system can be updated efficiently and effectively.
What is the Parent Zone ?
Correct Answer:
A, B
Explanation
The Parent Zone is the Authoritative name server that contains all the information of the Zone. It holds the DNS records for the domain and is responsible for delegating subdomains to other name servers.
The Parent Zone is not a physical representation but rather a logical concept in the DNS hierarchy. It refers to the higher-level domain that delegates control to subdomains.

FAQ
302 Exam FAQ
Common questions about the exam itself
What hands-on experience should I have before taking the 302 exam?
F5 recommends that candidates have at least one year of experience as BIG-IP DNS administrator with the ability to deploy and test configurations, and troubleshoot and remedy common misconfigurations. You need practical experience configuring GSLB, DNS Express, zone transfers, and troubleshooting common DNS issues on real BIG-IP systems.
Is the F5-CA (Certified BIG-IP Administrator) a hard requirement?
Prior to attempting this certification, candidates must earn the F5 Certified BIG-IP Administrator certification. You cannot schedule exam 302 until you hold an active F5-CA credential, which requires passing exams 101 and 201.
How difficult is the 302 exam compared to other F5 Technology Specialist exams?
Certification exams are demanding. We recommend giving yourself ample time to prepare beforehand and encourage you to take advantage of the support we offer. The 302 requires solid understanding of DNS protocols, GSLB architecture, and hands-on troubleshooting skills. Many candidates find the Design and Architect domain challenging because it demands the ability to apply knowledge to real scenarios.
How long does it realistically take to prepare for 302?
Most candidates with one year of hands-on BIG-IP DNS experience need 6 to 12 weeks of focused study combining the official F5 training course, exam blueprint review, and hands-on lab practice. Heavy preparation requirements depend on gaps in your current experience with specific features like DNSSEC, topology load balancing, or iQuery troubleshooting.
What exam delivery method is used for 302?
BIG-IP exams are delivered at Pearson VUE testing centers worldwide. The exam is computer-based with multiple choice questions, and some questions contain exhibits or scenarios you must analyze to answer.
What are the retake rules if I fail the 302 exam?
The first time you fail an exam, you must wait 15 days. For subsequent failures the wait times increase to 30 days on the second attempt, 45 days on the third, and a full year on the fifth or later attempt. You can retake as many times as needed within the validity window.
How long does the BIG-IP DNS Specialist certification stay valid?
F5 Certifications are valid for two years. To maintain your credential, you must pass the 302 exam again before your expiration date. F5 does offer a 1-month grace period beyond certification expiration to account for unexpected issues renewing your exams.
What is the 302 exam code officially called and which track is it part of?
Candidates that pass Exam 302 will receive the F5 Certified! Technology Specialist, BIG-IP DNS certification. Exam 302 is the sole requirement for the F5 Certified Technology Specialist, BIG-IP DNS credential, and is a DNS and global load balancing specialization.
Which exam should I take after 302 for further F5 certifications?
Receiving the F5-CTS, BIG-IP DNS certification is a prerequisite for the Cloud Solutions Expert certification tracks. You can also pursue other Technology Specialist exams like 303 (ASM) or 304 (APM) in parallel, or move toward the Cloud Solutions Expert track once you hold exam 302.
What is the cost of the 302 exam and what does that price include?
All F5 exams are currently priced at US$180 (not including local taxes and fees) per exam, per attempt. This is a one-time fee per attempt. If you fail and need to retake, you pay the full $180 fee again, and regional taxes may apply depending on where you sit the exam.
