質問 # 14
A BIG-IP Administrator makes a configuration change to a Virtual Server on the Standby device of an HA pair. The HA pair is currently configured with Auto-Sync Enabled. What effect will the change have on the HA pair configuration?
正解：D
解説：
Understanding High Availability (HA) synchronization behavior is critical for maintaining a stable environment. In a device group where "Auto-Sync" is enabled, the BIG-IP system monitors the management plane for any configuration updates across all members. While best practices often suggest making changes on the "Active" device, TMOS allows changes on any device within the group. When a change is made on the
"Standby" device, the system detects a configuration mismatch and, because Auto-Sync is enabled, it automatically pushes those changes to the other devices in the sync group, including the current Active member. To troubleshoot if this is working correctly, the administrator should review the "Sync Status" stats in the Configuration Utility. If the changes do not propagate, it suggests9 a breakdown i10n the HA trust relationship or network connectivity issues on the failover VLAN. Proper interpretation of this scenario confirms that the HA functionality is operating correctly, ensuring that both devices have a consistent set of virtual servers and pools, which is vital f11or seamless failover.

A BIG-IP Administrator needs to determine why only one pool member is showing connections from the virtual server, resulting in uneven load balancing.
What two reasons would cause uneven load balancing? (Choose two answers)
正解：A、D
解説：
Uneven load balancing on a BIG-IP system typically occurs when traffic is not distributed evenly across all available pool members. One common reason is that monitors have marked down multiple pool members (Option B). When health monitors fail for specific pool members, BIG-IP automatically removes those members from load-balancing decisions. As a result, traffic is sent only to the remaining healthy member, creating the appearance that load balancing is not functioning correctly. This behavior is expected and aligns with BIG-IP's design to ensure traffic is sent only to healthy resources.
Another frequent cause is the presence of a persistence profile on the pool or virtual server (Option C). Persistence (such as source address or cookie persistence) forces subsequent client connections to be sent to the same pool member for session continuity. While persistence is critical for certain applications, it can override the load-balancing algorithm and cause most or all traffic to be directed to a single pool member, especially during low traffic volumes or testing scenarios.
The other options are incorrect because a virtual server marked down (Option A) would not pass traffic at all, and all pool members marked down (Option D) would result in no connections rather than uneven distribution. This analysis follows standard BIG-IP troubleshooting methodology using pool status, monitor results, and persistence configuration review.
質問 # 16
A custom HTTP monitor is failing to a pool member 10.10.3.75:8080 that serves up www.example.com. A ping works to the pool member address. The SEND string is:
GET / HTTP/1.1 \r\nHost: www.example.com\r\nConnection: Close\r\n\r\n.
Which CLI tool syntax will show whether the web server returns the correct HTTP response?
正解：B
解説：
To manually verify a health monitor's "Send String" from the BIG-IP command line, the curl utility is the preferred tool because it allows for custom header insertion.
Matching the Monitor String: The monitor string requires an HTTP/1.1 request which must include a "Host" header. Option A correctly uses the --header (or -H) flag to pass Host:
www.example.com to the specific IP and port of the pool member.
Troubleshooting Logic: If curl--header 'Host: www.example.com' 'http://10.10.3.75:8080/' returns a
"200 OK" but the BIG-IP monitor still shows "Down," the administrator should check if the Receive String in the monitor configuration matches the output provided by curl.
質問 # 17
A BIG-IP Administrator observes the following messages in the /var/log/ltm log:
warning tmm[pid]: 011e0002: sweeper_segment_cb_any: Aggressive mode /Common/default-eviction-policy activated (0) (global memory) (345209/690176 pages) warning tmm[pid]: 011e0003: Aggressive mode sweeper /Common/default-eviction-policy (0) (global memory) 1 connections killed warning tmm[pid]: 011e0003: Aggressive mode sweeper /Common/default-eviction-policy (0) (global memory) 1 connections killed warning tmm[pid]: 011e0003: Aggressive mode sweeper /Common/default-eviction-policy (0) (global memory) 1 connections killed What is happening when the BIG-IP Administrator sees the messages displayed above? (Choose two answers)
正解：B、D
解説：
Comprehensive and Detailed 150 to 250 Words Explanation From BIG-IP Administration, Support, and Troubleshooting Documents:
These log messages indicate that the BIG-IP system's Traffic Management Microkernel (TMM) has entered aggressive eviction mode due to high global memory utilization. When TMM memory consumption reaches critical thresholds, BIG-IP activates the default eviction policy to protect system stability and prevent a full traffic processing failure. This condition directly corresponds to Option A, where the global eviction policy is triggered because TMM memory resources are nearing exhaustion.
Once aggressive mode is activated, BIG-IP begins using the connection sweeper mechanism, which selectively terminates existing connections to free memory. The repeated log entries stating "1 connections killed" confirm that the system is reaping some connections, not all connections. This behavior matches Option C. The eviction process is incremental and controlled, targeting idle, low-priority, or least-recently-used connections first to minimize impact on active traffic.
Option B is incorrect because BIG-IP does not drop all connections during aggressive mode; it only removes enough connections to relieve memory pressure. Option D is also incorrect because TMM eviction is based on TMM global memory usage, not swap memory utilization. TMM does not rely on swap space in the same way the host Linux system does.
These messages are a critical warning sign that the system is under memory stress and may require traffic optimization, connection limits, or hardware scaling.
質問 # 18
A BIG-IP Administrator uses backend servers to host multiple services per server. There are multiple virtual servers and pools defined, referencing the same backend servers. Which load balancing algorithm is most appropriate to have an equal number of connections on each backend server?17
正解：D
解説：
When load balancing is not working as 23expected and connections appear skewed across physical hardware, the administrator must distinguish between "member"24 and "node" level balancing. A "member" refers to a specific IP and Port combination (e.g., 10.1.1.1:80), whereas a "node" refers to the underlying IP address (10.1.1.1) regardless of the port25. If a single server hosts multiple services (Web, FTP, API) across different pools, using "Least Connections (member)" would only balance connections within each individual pool26.
This could lead to a scenario where one server is overwhelmed because it is winning the "least connections" count in three different pools simultaneously. By selecting "Least Connections (node)," the BIG-IP tracks the total number of concurrent connections to the physical IP address across all pools it belongs to27. This ensures that the administrator can maintain an equal distribution of work across the hardware, preventing performance degradation on backend servers that host multiple application services.
