F5-CTS-LTM BIG-IP Local Traffic Manager Practice Question
An LTM is configured with a 'OneConnect' profile. What is the primary purpose of this feature?
⚠ Common exam trap
Candidates often confuse OneConnect with HTTP Keep-Alive. While they are related, OneConnect manages the BIG-IP to server connection pooling, whereas Keep-Alive is strictly a client to BIG-IP communication mechanism.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
To reuse backend TCP connections for multiple client requests.
OneConnect enables TCP connection pooling between the BIG-IP and the backend servers. By keeping backend connections open even after a client request finishes, the LTM avoids the overhead of repeated TCP handshakes. This is essential for high-performance web applications, as it significantly reduces latency and server CPU consumption, allowing the backend servers to handle a higher volume of concurrent user requests more efficiently than they could with per-request connection establishment.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
To encrypt traffic between the BIG-IP and the backend servers.
Why it's wrong here
OneConnect is unrelated to encryption. Server-side encryption is handled exclusively by Server SSL profiles. OneConnect is an optimization tool for connection management at the transport layer, specifically designed to reduce the overhead associated with establishing new TCP connections for every single HTTP request.
- ✗
To enable persistence for HTTP traffic.
Why it's wrong here
Persistence is handled by persistence profiles, such as cookie or source address affinity profiles. While OneConnect can occasionally interfere with certain types of persistence if misconfigured, it does not provide persistence itself. Its sole role is the efficient reuse of existing connections to backend servers.
- ✓
To reuse backend TCP connections for multiple client requests.
Why this is correct
OneConnect manages a pool of idle TCP connections to the backend servers. When a new request arrives, the LTM can reuse an existing established connection to a pool member rather than initiating a new three-way handshake, reducing latency and resource utilization on the backend servers.
- ✗
To limit the number of concurrent connections per client.
Why it's wrong here
Connection limiting is handled by the 'Connection Limit' setting on the Virtual Server or pool member, or via iRules. OneConnect works in the opposite direction by trying to maximize connection reuse, not by restricting client connectivity or enforcing per-client connection thresholds on the BIG-IP.
