Free F5101 sample questions

1. A junior engineer configures a BIG-IP virtual server to route requests based on the HTTP Host header and URI path. At which OSI layer must the device inspect traffic to make these routing decisions?

   • A. Layer 7 (Application), because Host headers and URI paths live in the HTTP payload
   • B. Layer 4 (Transport), because routing uses TCP port numbers only
   • C. Layer 3 (Network), because routing is based on destination IP addresses
   • D. Layer 2 (Data Link), because forwarding relies on MAC address tables
   Show answer

   Correct: A. Host headers and URI paths are part of the HTTP application protocol, so the BIG-IP must operate at Layer 7 to read them. Layer 4 is incorrect because it only sees TCP/UDP ports, not HTTP content. Layer 3 only sees IP addresses, and Layer 2 only sees MAC addresses, so neither can inspect application-layer data.

2. While comparing a Layer 4 virtual server to a Layer 7 virtual server on BIG-IP, an engineer lists capabilities unique to Layer 7 processing. Which statements correctly describe Layer 7 load balancing? (Choose TWO)

   • A. It can route traffic based on the URI path or HTTP Host header
   • B. It can insert or rewrite HTTP headers and modify content
   • C. It forwards packets using only source and destination IP and port
   • D. It operates without ever parsing the application payload
   • E. It is always faster and uses less CPU than Layer 4 forwarding
   Show answer

   Correct: A and B. Layer 7 processing reads the HTTP payload, enabling URI/host-based routing and header or content rewriting. Forwarding by IP and port only describes Layer 4, not Layer 7. Operating without parsing payload is the opposite of Layer 7 behavior. Layer 7 is not faster than Layer 4 because parsing application data consumes more CPU, so that claim is incorrect.

3. An architect needs web application firewall protection plus load balancing on a single BIG-IP appliance. Which two licensed modules deliver these specific functions on the TMOS platform?

   • A. LTM for load balancing and ASM/Advanced WAF for application firewalling
   • B. APM for load balancing and AFM for application firewalling
   • C. DNS for load balancing and AVR for application firewalling
   • D. GTM for load balancing and iHealth for application firewalling
   Show answer

   Correct: A. LTM (Local Traffic Manager) handles load balancing and ASM/Advanced WAF provides web application firewall protection. APM is for access policy, not load balancing, and AFM is a network firewall, not a WAF, so that pair is wrong. DNS/GTM handles global DNS load balancing and AVR is analytics, so neither matches both required functions.

4. During a platform review, a colleague asks what the acronym TMOS stands for and what role it plays on a BIG-IP system. Which description is accurate?

   • A. Traffic Management Operating System, F5's purpose-built OS that runs BIG-IP modules
   • B. Transport Mode Operating Standard, a protocol used to encrypt management traffic
   • C. Total Memory Optimization Service, a daemon that compresses pool member tables
   • D. Tenant Multiplexing Orchestration Server, a hypervisor used only for Virtual Edition
   Show answer

   Correct: A. TMOS is the Traffic Management Operating System, the foundation that hosts all BIG-IP modules such as LTM and ASM. It is not an encryption protocol, so the transport mode answer is wrong. It is not a memory daemon, and it is not a hypervisor, so the optimization service and orchestration server definitions are incorrect.

5. A cloud team wants to deploy BIG-IP functionality inside AWS and Azure without buying physical hardware. Which F5 deployment form factor should they choose?

   • A. BIG-IP Virtual Edition (VE), a software image that runs on hypervisors and public clouds
   • B. BIG-IP iSeries appliance, which must be racked in an on-premises datacenter
   • C. BIG-IP VIPRION chassis, a modular hardware blade system for large deployments
   • D. BIG-IP iHealth, a hosted diagnostic portal that processes qkview files
   Show answer

   Correct: A. Virtual Edition is the software image of BIG-IP that runs on hypervisors and public clouds like AWS and Azure, requiring no hardware. The iSeries and VIPRION are physical appliances and chassis, so they cannot run as cloud software. iHealth is a diagnostic service, not a deployment form factor, so it does not apply.
