F5 BIG-IP Administration Support and Troubleshooting Sample Questions (Q42-Q47):NEW QUESTION # 42
A BIG-IP Administrator configured the following virtual server to pass traffic on all addresses and ports. After configuration is completed, the BIG-IP Administrator notices that the virtual server is unable to pass traffic.
ltm virtual forwarding_any_vs {
destination 0.0.0.0:any
ip-forward
mask 255.255.255.255
profiles {
fastL4 { }
}
serverssl-use-sni disabled
source 0.0.0.0/0
translate-address disabled
translate-port disabled
}
Which part of the configuration is the cause of the issue? (Choose one answer)
  • A. Incorrect translate-address configured
  • B. Incorrect mask 255.255.255.255
  • C. Incorrect destination configured
Answer: B
Explanation:
This virtual server is intended to function as a forwarding (IP-forwarding) virtual server, which is commonly used for routing or firewall-style deployments where BIG-IP forwards traffic transparently without load balancing or address translation. For a forwarding virtual server to match and pass all traffic, the destination must be configured as 0.0.0.0:any with a mask of 0.0.0.0, not 255.255.255.255.
The configured mask 255.255.255.255 represents a /32 host mask, which restricts the virtual server to matching traffic destined only for the exact IP address 0.0.0.0. Since 0.0.0.0 is not a valid routable destination for normal traffic, no packets will ever match the virtual server, causing it to pass no traffic at all.
This is a well-documented BIG-IP behavior:
destination 0.0.0.0:any
mask 0.0.0.0
together define a catch-all forwarding virtual server.
The destination itself (Option A) is correct for a forwarding VS, and disabling address translation (Option C) is expected and required for IP-forwarding mode. Therefore, the incorrect subnet mask is the sole reason the virtual server is not functioning as expected.

NEW QUESTION # 43
A Virtual Server uses an iRule to send traffic to pool members depending on the URI. The BIG-IP Administrator needs to modify the pool member in the iRule. Which event declaration does the BIG-IP Administrator need to change to accomplish this?
  • A. CLIENT_ACCEPTED
  • B. SERVER_CONNECTED
  • C. HTTP_RESPONSE
  • D. HTTP_REQUEST
Answer: D
Explanation:
Comprehensive and Detailed Explanation From BIG-IP Administration Support and Troubleshooting documents: In F5 TMOS administration, the traffic flow is processed through specific event huddles w3ithin iRules. To troubleshoot or m4odify traffic based on a URI (Uniform Resource Identifier), the BIG-IP system must first parse the application-layer data. The HTTP_REQUEST event is triggered when the system has fully received and parsed the HTTP request headers from the client5. This is the correct point to implement logic that selects a pool or pool member based on the path or file requested (e.g., /images or /api). Using CLIENT_ACCEPTED would be too early in the troubleshooting process because that event triggers at the L4 (TCP) connection establishment phase, before any URI information is available6. Conversely, HTTP_RESPONSE occurs during the return traffic from the server, which is too late to make a load balancing decision7. For troubleshooting virtual server behavior where URIs are involved, ensuring the iRule is attached to a Virtual Server with an HTTP profile and using the HTTP_REQUEST event is essential for proper traffic steering and inspection.

NEW QUESTION # 44
An organization is reporting slow performance accessing their Intranet website, hosted in a public cloud. All employees use a single Proxy Server with the public IP of 104.219.110.168 to connect to the Internet. What should the BIG-IP Administrator of the Intranet website do to fix this issue?
  • A. Change Fallback Persistence Profile to source_addr
  • B. Change Default Persistence Profile to cookie
  • C. Change Source Address to 104.219.110.168/32
  • D. Change Load Balancing Method to Least Connection
Answer: B
Explanation:
This scenario describes a classic network performance issue known as the "Mega-Proxy" problem. When an organization routes all employee traffic through a single proxy server, the BIG-IP sees thousands of unique users as having the exact same source IP address. If the administrator has configured "Source Address Affinity" persistence, the BIG-IP will correctly follow the rule but incorrectly route all users to the same single backend pool member. This creates a severe load imbalance where one server is overwhelmed while others remain idle, leading to poor application response times. To resolve this, the administrator must change the persistence profile to "HTTP Cookie". Cookie-based persistence allows the BIG-IP to place a unique identifier in each user's browser, allowing the system to distinguish between individual sessions even if they share the same source IP. This fix ensures that traffic is distributed evenly across the pool members, restoring4 the expect5ed load balancing functionality and resolving the slow performance reported by users behind the corporate proxy.

NEW QUESTION # 45
A BIG-IP Administrator observes the following pool member status message:
Pool /Common/testpool member /Common/10.120.0.5:8090 monitor status down
[/Common/http: up, /Common/http2: down; last error:]
Why is this pool member being marked down? (Choose one answer)
  • A. The pool member is currently only serving HTTP traffic.
  • B. The pool member is currently only serving HTTPS traffic.
  • C. The pool member is currently only serving TCP traffic.
  • D. The pool member is currently only serving UDP traffic.
Answer: A
Explanation:
The pool member is marked DOWN because it is monitored by multiple health monitors, specifically an HTTP monitor and an HTTP/2 monitor. The status message clearly shows that the HTTP monitor is UP, while the HTTP/2 monitor is DOWN. In BIG-IP, when multiple monitors are assigned to a pool member, the default behavior is AND logic, meaning all assigned monitors must succeed for the pool member to be considered healthy.
In this scenario, the server is responding successfully to standard HTTP (likely HTTP/1.1) requests but does not support or respond correctly to HTTP/2 requests. As a result, the HTTP/2 monitor fails, which causes the overall monitor status to be DOWN, even though HTTP traffic itself is working.
This behavior is expected and documented in BIG-IP monitoring logic. Unless the monitor rule is explicitly changed to "at least one of", a single failing monitor will mark the pool member down. Therefore, the correct conclusion is that the pool member is only serving HTTP traffic, not HTTP/2.
The resolution would be to either remove the HTTP/2 monitor, correct the application to support HTTP/2, or adjust the monitor rule to match the intended health-check logic.

NEW QUESTION # 46
Which two methods should the BIG-IP Administrator use to troubleshoot a pool member that has been marked DOWN by its health monitor? (Choose two answers)
  • A. Collect a TCPdump packet capture for the DOWN pool member.
  • B. Enable monitor logging for the pool member that is DOWN.
  • C. Review the pool and pool-member statistics table for error data.
  • D. Review the BIG-IP routing table using netstat -rn to show all routes.
Answer: A,B
Explanation:
When a pool member is marked DOWN, it indicates that the configured health monitor is failing. The most effective troubleshooting approach is to focus on the monitor behavior and the actual traffic between BIG-IP and the pool member.
Enabling monitor logging (Option B) is a recommended first step. Monitor logging provides detailed information about why the health check is failing, such as timeouts, connection refusals, incorrect responses, or unexpected status codes. This directly correlates with BIG-IP troubleshooting best practices and allows administrators to confirm whether the failure is due to application behavior, incorrect monitor configuration, or network reachability.
Collecting a TCPdump packet capture (Option D) is also a highly effective method. A packet capture allows the administrator to verify whether the monitor probes are being sent, whether responses are received, and whether packets are being dropped, reset, or malformed. This is especially valuable when diagnosing firewall issues, SSL problems, or application-level failures.
Reviewing pool statistics (Option C) is useful for general monitoring but does not explain why a health monitor is failing. Reviewing the routing table (Option A) is typically unnecessary unless there is evidence of a broader routing issue affecting multiple destinations.
