F5 BIG-IP Administration Support and Troubleshooting 認定 F5CAB5 試験問題 (Q30-Q35):

質問 # 30
What is the purpose of a core dump file?

正解：A

解説：
Core dumps help analyze system or application crashes.


質問 # 31
A traffic group includes four devices. The failover method is HA order. The failover order is:
BIGIP-D
BIGIP-B
BIGIP-C
BIGIP-A
Auto fallback is enabled. BIGIP-D has been forced to standby. BIGIP-B was active before being rebooted. Which device is active when BIGIP-B is up after the reboot?

正解：C

解説：
To understand which device becomes active, we must look at how the BIG-IP system handles HA Order and Auto Fallback within a traffic group.
HA Order Mechanism: When a traffic group is configured with an "HA Order" list, the system prefers to host the traffic group on the highest-ranking available device in that list (1 being the highest).
The Impact of "Forced to Standby": BIGIP-D is the first choice in the order, but it has been "Forced to Standby." This state is persistent and manual; until an administrator releases the "Force to Standby" state, the device is ineligible to host the traffic group, effectively removing it from the top of the preference list.
Auto Fallback: When "Auto Fallback" is enabled, the traffic group will automatically migrate back to a higher-priority device in the HA order as soon as that device becomes available and is in a healthy "Standby" state.
The Scenario Logic: 1. BIGIP-D is ineligible (Forced Offline/Standby).
2. BIGIP-B is the next highest device in the HA Order (Rank 2).
3. While BIGIP-B was rebooting, the traffic group would have failed over to BIGIP-C (Rank 3).
4. Once BIGIP-B finishes booting and joins the cluster in a "Standby" state, the Auto Fallback setting triggers.
5. Because BIGIP-B is higher in the HA Order than the current active device (BIGIP-C) and the only device above it (BIGIP-D) is ineligible, the traffic group fails back to BIGIP-B.


質問 # 32
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：B

解説：
Comprehensive and Detailed Explanation From BIG-IP Administration Support and Troubleshooting documents: 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.


質問 # 33
Refer to the exhibit. A pool member fails the monitor checks for about 30 minutes and then starts passing the monitor checks. New traffic is NOT being sent to the pool member. What is the likely reason for this problem? (Choose one answer)

正解：D

解説：
In BIG-IP LTM, health monitors are used to determine if a pool member or node is "Up" and capable of processing traffic. Based on the provided exhibit, the specific configuration setting causing this behavior is Manual Resume.
Manual Resume (Enabled/Yes): When the Manual Resume setting is set to Yes, it changes the default behavior of how a pool member returns to service. Under normal circumstances (Manual Resume set to No), once a pool member starts passing its health check again, the BIG-IP system automatically marks it as "Up" and resumes sending traffic to it. However, with Manual Resume enabled, the system will continue to mark the pool member as "Down" (or "Unavailable") even after it passes the health check. It requires a manual intervention by an administrator to reset the status and allow traffic to flow again.
Exhibit Analysis: The screenshot clearly shows the Manual Resume radio button is selected as Yes. This explains why, even after the pool member "starts passing the monitor checks," it does not receive new traffic.


質問 # 34
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.
Plaintext
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?

正解：B

解説：
The failure of the Forwarding (IP) virtual server is caused by an incorrect Network Mask configuration for a wildcard destination.
Wildcard Destination: The administrator intends to create a "Wildcard" Virtual Server that listens for any destination IP address (0.0.0.0).
The Mask Conflict: A mask of 255.255.255.255 (or /32) tells the BIG-IP to look for a specific, single host address. When combined with 0.0.0.0, the system is literally looking for traffic destined for the IP 0.0.0.0, which is not a valid routable destination for standard traffic.
Correct Configuration: To allow the virtual server to catch traffic for any IP address, the mask must be changed to 0.0.0.0 (or /0). This signifies that the system should ignore all bits of the destination address and match everything.
Forwarding Logic: The rest of the configuration-including ip-forward (Forwarding IP type), translate-address disabled, and translate-port disabled-is correct for a BIG-IP acting as a router/gateway.
