NEW QUESTION # 53
A BIG-IP Administrator configured a virtual server with a pool of 3 members and selected the Round Robin load balancing method to evenly distribute traffic across the pool members. During initial testing, the virtual server failed to respond to http requests.
Plaintext
ltm virtual http.vs {
destination 10.10.1.100:http
ip-protocol tcp
mask 255.255.255.255
pool http.pool
profiles {
tcp{}
}
serverssl-use-sni disabled
source 0.0.0.0/0
translate-address enabled
translate-port enabled
}
ltm pool http_pool {
members {
10.10.1.101:http {
address 10.10.1.101
session monitor-enabled
state checking
}
10.10.1.102:http {
address 10.10.1.102
session monitor-enabled
state checking
}
}
monitor tcp
}
What configuration change on the BIG-IP will resolve this issue?
Answer: B
Explanation:
The issue described is a classic case of asymmetric routing in a "one-arm" or same-subnet topology.
Symptom Analysis: The Virtual Server (10.10.1.100) and the pool members (10.10.1.101 and 10.10.1.102) are on the same subnet.
The Problem: When a client sends a request to the VIP, the BIG-IP translates the destination IP but keeps the client's original source IP. The server receives the packet and sees a source IP from a different subnet. Instead of sending the response back to the BIG-IP, the server sends it directly to its default gateway. The client receives a response from the server's IP, which it doesn't recognize, causing the connection to fail.
The Solution: Enabling SNAT Auto Map ensures the BIG-IP changes the source IP of the packet to its own self-IP. This forces the pool member to send the response back to the BIG-IP, which then translates it correctly and sends it to the client.
Incorrect Options: Adding an HTTP profile (Option B) or an HTTP monitor (Option C) would enhance the configuration but would not fix the underlying Layer 3 routing issue causing the traffic drop.
NEW QUESTION # 54
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?
Answer: C
Explanation:
When a virtual server is not working as expected despite the pool members being marked "UP" (Green), the issue is frequently a return-path routing failure. If the BIG-IP forwards a request with the original client's source IP address, the backend server will try to respond directly to that client. If the server does not have its default gateway pointed back to the BIG-IP, the response packet will be routed elsewhere (or dropped), resulting in a connection timeout for the user. To resolve this, the administrator must configure "Source Address Translation" (SNAT). By setting SNAT to "Automap" or a specific SNAT address, the BIG-IP replaces the client's IP with its own internal self-IP. The backend server then sees the BIG-IP as the source and sends the response back to it locally. This troubleshooting step ensures a functional, symmetric tr18affic flow. Identifying the need for SNAT is one of the most common troubleshooting tasks for new virtual server deployments where the BIG-IP is not the default gateway for the backend servers.
NEW QUESTION # 55
Some users who connect to a busy Virtual Server have connections reset by the BIG-IP system.
Pool member resources are NOT a factor in this behavior. What is a possible cause for this behavior?
Answer: B
Explanation:
When troubleshooting intermittent connection resets on a "busy" Virtual Server, the administrator must examine the configured thresholds. A "Connection Limit" is a hard cap on the number of concurrent connections a Virtual Server or pool member can handle. If this limit is set too low, the BIG-IP will reset any new connection attempts once the threshold is reached. The key indicator in this scenario is that the problem only affects "some users" and happens when the server is
"busy," suggesting that the system is hitting a capacity ceiling rather than suffering from a persistent configuration error. Unlike a missing SSL profile, which would likely cause all connections to fail, or a "Connection Rate Limit," which throttles how fast connections arrive, a
"Connection Limit" focuses on the total volume. Identifying this as the cause requires reviewing the Virtual Server's statistics to see if the "Current Connections" count is consistently peaking at the configured limit value.
NEW QUESTION # 56
Clients report that they cannot reach the virtual server vs-production on port 80, but are able to ping the virtual server address. The configuration is shown below:
Plaintext
ltm virtual vs-production {
destination 10.99.20.50:http
ip-protocol tcp
mask 255.255.255.255
profiles {
http {}
tcp {}
}
source 192.168.0.0/16
translate-address enabled
translate-port enabled
vlans {
external
}
vlans-enabled
}
What is the cause?
Answer: D
Explanation:
The issue is caused by the Source Address restriction configured on the virtual server.
Source Filter: The configuration contains the line source 192.168.0.0/16. This acts as an implicit Access Control List (ACL). The virtual server will only accept and process TCP connections if the client's source IP address falls within the 192.168.x.x range.
Why Ping Works: ICMP (Ping) is handled by the Virtual Address object, not the Virtual Server object. Unless ICMP is specifically disabled on the Virtual Address, it will respond to pings from any subnet, even if the Virtual Server itself is restricted by a source filter or is even disabled.
NEW QUESTION # 57
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)
Answer: C,D
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.
