質問 # 13
A BIG-IP device sends out the following SNMP trap: big-ipo.f5.com - bigipExternalLinkChange Link: 1.0 is DOWN. Where in the BIG-IP Configuration utility should the BIG-IP Administrator verify the current status of Link 1.0?
正解：C
解説：
Comprehensive and Detailed Explanation From BIG-IP Administration Support and Troubleshooting documents: Identifying network-level performance issues often starts with investigating hardware-level alerts78. In F5 terminology, a "Link" like "1.0" or "1.1" refers to a physical interface on the appliance79. When an SNMP trap reports that a link is "DOWN," it indicates a loss of signal or an administrative shutdown of the physical port80. To verify this, the administrator must navigate to Network > Interfaces > Interface List81. This screen provides real-time status, showing whether the interface is "up," "down," or "uninitialized," as well as any media speed or duplex mismatches that could be causing performance degradation82. Troubleshooting this is the first step in resolving "pool member down" or "VLAN failsafe" issues, as a down interface will take down any VLANs associated with it, immediately halting all traffic flow for the services relying on that physical path.
質問 # 14
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：C
解説：
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.
質問 # 15
A pool member is exhibiting frequent up-and-down state changes, leading the BIG-IP Administrator to suspect a health monitor issue. Which specific log file should the BIG-IP Administrator review to diagnose the problem?
正解：B
解説：
The Local Traffic Manager (LTM) log file is the primary repository for all events related to load balancing objects, including virtual servers, pools, and nodes.
* Monitor Logging: When a health monitor marks a pool member as "UP" or "DOWN," the system generates a log entry in /var/log/ltm.
* Diagnosing Flaps: To troubleshoot "flapping" (frequent state changes), an administrator would look for messages like 01010028:3: Pool /Common/http_pool member /Common/10.10.1.1:80 monitor status down followed quickly by an "up" status. This log provides the timestamp and the specific monitor that triggered the state change.
質問 # 16
A BIG-IP Administrator receives reports from users that SSL connections to the BIG-IP device are failing. Upon checking the log files, the administrator notices: SSL transaction (TPS) rate limit reached. stats show a maximum of 1200 client-side SSL TPS and 800 server-side SSL TPS.
What is the minimum SSL license limit required to handle this peak?
正解：B
解説：
Troubleshooting failed SSL handshakes involves interpreting the resource limits defined by the system's license. The log message SSL transaction (TPS) rate limit reached indicates the BIG-IP is dropping SSL connections because it has exceeded its licensed "Transactions Per Second" capacity. When analyzing stats to determine the correct license level, the administrator must focus on "Client- side" SSL TPS. This represents the initial encrypted handshakes between users and the BIG-IP virtual servers91. In this scenario, the peak client-side demand is 1200 TPS.
While the 800 server-side transactions represent re-encryption toward the backend, F5's primary SSL TPS license limits typically apply to the client-facing side of the traffic flow. Therefore, to resolve the intermittent connectivity issues and ensure the virtual server works reliably during peaks, the license must be upgraded to at least 1200 TPS. Confirming this peak via statistics andcomparing it to the current license is a standard troubleshooting step for SSL performance issues.
質問 # 17
Which process is most likely responsible for high traffic processing CPU usage?
正解：D
解説：
TMM handles traffic processing and is usually responsible for high CPU under load.
