NEW QUESTION # 25
A BIG-IP Administrator creates a new Virtual Server. The end user is unable to access the page. During troubleshooting, the administrator learns that the connection between the BIG-IP system and server is NOT set up correctly. What should the administrator do to solve this issue? (Choose one answer)
Answer: A
Explanation:
The issue described is a classic symptom of asymmetric routing, which frequently occurs when the BIG-IP system and the back-end servers reside on the same subnet (often referred to as a "one-arm" deployment).
* The Routing Problem: By default, the BIG-IP system preserves the original client source IP address when forwarding traffic to a pool member. If the server is in the same subnet as the client or if the server's default gateway is not the BIG-IP, the server will attempt to send its response directly back to the client's IP address, bypassing the BIG-IP.
* Stateful Failure: Since the BIG-IP is a Full Proxy, it maintains a state table. Because the response packet never returns through the BIG-IP, the system cannot complete the three-way handshake or manage the application session, resulting in a connection failure for the user.
* The Solution (SNAT): Enabling Source Network Address Translation (SNAT) solves this by changing the source IP address of the request to an IP address owned by the BIG-IP (typically a self-IP).
* Requirement for Subnet Alignment: To ensure the server sends the response back to the BIG-IP, the translation address must be reachable. By using a self-IP configured in the same subnet as the servers, the BIG-IP ensures that the server sees the request coming from a local "neighbor." The server will then naturally send the response back to that self-IP, allowing the BIG-IP to translate the packet back and forward it to the client.
Why other options are incorrect:
* A: Disabling address translation would ensure the server-side traffic uses the client IP, making asymmetric routing inevitable in this scenario.
* B: This is technically contradictory; "Auto Map" specifically uses existing self-IPs and does not require or use a "SNAT pool" configuration.
* C: While using a specific translation address can work, it does not inherently guarantee the Layer 2
/Layer 3 reachability mentioned in the scenario as effectively as ensuring the self-IP is correctly placed in the server's subnet.
NEW QUESTION # 26
The BIG-IP Administrator is investigating whether better TCP performance is possible for a virtual server.
Which built-in profile should be tried first? (Choose one answer)
Answer: B
Explanation:
BIG-IP provides several built-in TCP profiles optimized for different traffic patterns and network conditions. When attempting to improve general TCP performance, the recommended starting point is f5-tcp-progressive.
According to the BIG-IP Administration: Data Plane Configuration documentation:
f5-tcp-progressive is designed as a balanced, general-purpose TCP optimization profile.
It dynamically adjusts TCP behavior to improve throughput and latency for most enterprise applications.
It is the recommended first-choice profile when tuning TCP performance before moving to more specialized profiles.
Why the other options are incorrect:
A . f5-tcp-legacy
This profile exists for backward compatibility and does not include modern TCP optimizations.
C . f5-tcp-mobile
This profile is optimized specifically for high-latency, lossy mobile networks and is not suitable for general-purpose environments.
D . No option
BIG-IP explicitly provides built-in TCP profiles for performance tuning; using none would forgo optimization opportunities.
Correct Resolution:
The administrator should first apply f5-tcp-progressive to evaluate potential TCP performance improvements before considering more specialized profiles.
NEW QUESTION # 27
The BIG-IP Administrator needs to load balance a pool of web servers. Load balancing should consider the number of connections that are active on that pool member.
Which load balancing method meets this requirement? (Choose one answer)
Answer: A
Explanation:
The requirement states that load balancing decisions must be based on the number of active connections on each pool member. This directly maps to the Least Connections (member) load balancing method.
According to the BIG-IP Administration: Data Plane Configuration documentation:
* Least Connections (member) selects the pool member with the fewest active connections at the time of the request.
* This method dynamically adapts to real-time traffic patterns and ensures that more heavily loaded pool members receive fewer new connections.
* It is especially effective for web servers where connection duration may vary and equal distribution of active sessions is desired.
Why the other options are incorrect:
* B. Round RobinDistributes connections sequentially without considering current load or active connections.
* C. Ratio (member)Distributes traffic based on static ratios, not real-time connection counts.
* D. Ratio (node)Uses predefined ratios at the node level and does not account for active connection counts.
Correct Resolution:
Using Least Connections (member) ensures that new connections are directed to the pool member currently handling the fewest active connections, meeting the stated requirement.
NEW QUESTION # 28
Refer to the exhibit.
A BIG-IP Administrator creates a new Virtual Server to load balance SSH traffic. Users are unable to log on to the servers.
What should the BIG-IP Administrator do to resolve the issue? (Choose one answer)
Answer: B
Explanation:
SSH is a Layer 4 TCP-based protocol that operates on TCP port 22 and does not use HTTP in any capacity. In the exhibit, the Virtual Server is configured with an HTTP Profile applied, which is inappropriate for SSH traffic and causes connection failures.
According to the BIG-IP Administration: Data Plane Configuration documentation:
* An HTTP profile must only be applied to Virtual Servers handling HTTP or HTTPS traffic.
* When an HTTP profile is attached, BIG-IP expects HTTP headers and attempts to parse application- layer data.
* Non-HTTP protocols such as SSH, FTP (control), SMTP, and other raw TCP services will fail if an HTTP profile is enabled.
Why the other options are incorrect:
* A. Set Protocol to UDPSSH uses TCP, not UDP. Changing the protocol would break SSH entirely.
* B. Set Source Address to 10.1.1.2The source address setting controls client access restrictions and is unrelated to protocol parsing issues.
* C. Set Destination Address/Mask to 0.0.0.0/0The destination address is already valid for a specific SSH service and does not impact protocol handling.
Correct Resolution:
The BIG-IP Administrator should remove the HTTP Profile (set it to None) so the Virtual Server functions as a pure Layer 4 TCP service, allowing SSH connections to pass through successfully.
NEW QUESTION # 29
A BIG-IP Administrator is creating a new Trunk on the BIG-IP device. What objects should be added to the new Trunk being created?
Answer: D
Explanation:
In F5 BIG-IP architecture, a Trunk is a logical aggregation of physical interfaces designed to increase bandwidth and provide link redundancy through 802.3ad Link Aggregation Control Protocol (LACP).
When creating a Trunk object within the BIG-IP configuration, the administrator must assign physical Interfaces to it - these are the underlying hardware ports (e.g., 1.1, 1.2, 1.3) that will be bundled together to form the aggregated logical link.
It is critical to understand the layered object hierarchy on the BIG-IP platform:
* Interfaces # assigned to Trunks
* Trunks (or individual Interfaces) # assigned to VLANs (as tagged or untagged members)
* VLANs # assigned Self IP addresses
* Self IPs / Routes # configured at the network layer above
VLANs are not added to a Trunk; rather, a Trunk is added as a member of a VLAN. IP addresses and network routes are configured independently at a higher abstraction layer and have no direct association with Trunk creation.
This layered design ensures proper separation of concerns across the data plane. Misunderstanding this hierarchy is a common configuration error that can result in traffic forwarding failures.
