質問 # 76
A BIG-IP Administrator makes a configuration change to the BIG-IP device. Which file logs the message regarding the configuration change?
正解：D
解説：
Comprehensive and Detailed Explanation From BIG-IP Administration Support and Troubleshooting documents: Troubleshooting configuration-related issues requires a clear trail of what was changed and by whom. The BIG-IP system includes a dedicated audit logging feature for this purpose28. Whenever a system object-such as a virtual server, pool, or iRule-is created, modified, or deleted, the system records the event in /var/log/audit29. These logs provide critical context during troubleshooting by showing if a performance drop or traffic failure coincided with a specific administrative action30. Unlike /var/log/ltm, which focuses on local traffic events like pool member status changes, or /var/log/secure, which handles authentication attempts, the audit log specifically tracks the "how" and "when" of configuration changes31. This is a vital resource for administrators to determine if a virtual server is not working as expected due to a recent manual change or an automated system action, allowing for a rapid "rollback" or correction of the configuration.
質問 # 77
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?
正解：C
解説：
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.
質問 # 78
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?
正解：D
解説：
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.
質問 # 79
A BIG-IP Administrator suspects that one of the BIG-IP device power supplies is experiencing power outages. Which log file should the BIG-IP Administrator check to verify the suspicion?
(Choose one answer)
正解：D
解説：
According toofficial F5 documentation (K52015891 ?Troubleshooting BIG-IP power supply issues),hardware-related alerts for power supplies, fans, and chassis components are logged in
/var/log/ltm.
When a BIG-IP device experiences a power supply issue--such as failure, intermittent outages, or fan-related faults--the system generates alerts through internal platform monitoring services.
These alerts are written to the/var/log/ltmfile and often appear with messages similar to:
Chassis power supply 2 has experienced an issue. Status is as follows: FAN=bad; STATUS=bad.
This makes /var/log/ltm theauthoritative log filefor identifying and verifying power supply and chassis-related problems on BIG-IP systems.
質問 # 80
Without decrypting, what portion of an HTTPS session is visible with a packet capture?
正解：A
解説：
When analyzing HTTPS traffic using tools like tcpdump without access to the SSL private keys for decryption, only the Layer 2 through Layer 4 information remains visible.
* Visible Information: You can see the Source and Destination IP addresses, TCP ports, and the TLS handshake headers (such as the Server Name Indication/SNI in the Client Hello).
* Encrypted Information: Once the encrypted tunnel is established, all Layer 7 data is masked. This includes HTTP Request/Response Headers (Option A and D) and Cookies (Option C).
* Troubleshooting Note: To see the headers or cookies, an administrator must either perform the packet capture on the "server-side" of the BIG-IP (if it is performing SSL Offload) or use a tool like Wireshark with the appropriate SSL keys loaded.
