質問 # 38
Refer to the exhibit.
A user with IP address 192.168.162.70 is unable to connect to an HTTP application. What is a possible cause within the Virtual Server configuration?
正解：B
解説：
The failure to connect is caused by a restrictive Source Address filter configured on the Virtual Server.
* Source Address Filtering: In the BIG-IP system, the Source Address field on a Virtual Server acts as an implicit Access Control List (ACL). Only traffic originating from a client IP address that matches the specified network range will be accepted and processed by the Virtual Server.
* Analyzing the Exhibit: The provided configuration for vs_http shows the Source Address is set to
10.128.10.0/24. This means the Virtual Server will only accept connections from the subnet ranging from 10.128.10.1 to 10.128.10.254.
* Identifying the Conflict: The user trying to connect has the IP address 192.168.162.70. Since
192.168.162.70 does not fall within the allowed 10.128.10.0/24 range, the BIG-IP system will not match this traffic to the Virtual Server, effectively blocking the connection attempt.
* Evaluation of Other Options:
* All Ports (Option A): Configuring a Virtual Server for "All Ports" (port 0) allows it to handle traffic for any destination port, which would not block a standard HTTP application.
* Destination Address (Option B): The destination address 192.168.162.80 is the Virtual IP (VIP) users should be connecting to; this is a standard configuration and not the cause of the failure for a user reaching out to it.
* Standard Type (Option C): A "Standard" Virtual Server is the most common type used for HTTP applications as it allows for Layer 7 profiles and full proxy capabilities.
質問 # 39
A BIG-IP Administrator notices that one of the servers that runs an application isNOTreceiving any traffic.
The BIG-IP Administrator examines the configuration status of the application and observes the displayed monitor configuration and affected pool member status.
What is the possible cause of this issue? (Choose one answer)
正解：B
解説：
The key clue in the exhibit is the pool member's availability showing"Offline (Enabled) - Parent down". In BIG-IP terminology, a pool member inherits the status of itsparent node. If thenodeis marked down (for example, by a node-level monitor or a default "node is down" condition), thenall pool members using that node IPwill also be marked down and will not receive any traffic, even if the application service on the member port might be healthy.
While the HTTPS monitor configuration (send/receive strings) is displayed, the statusspecificallyindicates anode (parent) failure, not a service-level failure. If the problem were the application not matching the receive string, you would typically see the member down due to themember's monitorfailing (and the status would reflect monitor failure details), rather than "parent down." Option D is too broad; BIG-IP can generally reach the subnet (other servers work), and this symptom points to a specific node condition. Option C is incorrect because HTTP/1.1 is commonly used for monitoring and is valid when properly formatted (especially with a Host header). Therefore, the most likely cause is that thenode health monitor is not responding, causing the node-and consequently the member-to be marked down.
質問 # 40
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?
正解：A
解説：
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.

Which command displays ARP table entries?
正解：D
解説：
Used to verify IP-to-MAC address mappings.
質問 # 42
Plaintext
warning tmm[<pid>]: 011e0002:4: sweeper_segment_cb_any: Aggressive mode /Common/default-eviction- policy activated (0) (global memory). (345209/690176 pages) warning tmm[<pid>]: 011e0003:4: Aggressive mode sweeper: /Common/default-eviction-policy (0) (global memory) 1 Connections killed What is happening when the BIG-IP Administrator sees the messages in the LTM log displayed above? (Pick the 2 correct responses below)
正解：A、D
解説：
These log messages indicate that the BIG-IP system is under significant resource pressure and has activated its Adaptive Connection Management.
* Global Eviction Policy: The message Aggressive mode ... activated (global memory) confirms that the system has reached a memory utilization threshold that triggers the eviction policy. This happens because TMM (the data plane) is running low on available memory pages.
* Sweeper/Reaping: Once in "Aggressive mode," the BIG-IP "sweeper" starts reaping (terminating) connections to free up memory. The log Connections killed confirms this is occurring.
* Impact: The system does not drop all connections; it targets connections based on the eviction policy (e.g., oldest connections or those exceeding limits) to bring memory usage back to safe levels. Thus, some connections will be dropped (Option A), and the cause is TMM memory exhaustion (Option C).
