質問 # 67
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?
正解：D
解説：
When load balancing is not working as expected and connections appear skewed across physical hardware, the administrator must distinguish between "member" 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 port. If a single server hosts multiple services (Web, FTP, API) across different pools, using "Least Connections (member)" would only balance connections within each individual pool. 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 to. 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 # 68
Which tool helps inspect SSL handshake issues?
正解：B
解説：
This tool tests SSL/TLS connections and reveals handshake problems.
質問 # 69
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：A
解説：
According to official 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/ltm file 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 the authoritative log file for identifying and verifying power supply and chassis-related problems on BIG-IP systems.
The other log files are not appropriate for this purpose:
/var/log/daemon.log contains general daemon messages but is not the primary source for chassis hardware alerts.
/var/log/kern.log logs kernel-level events, not platform power status.
/var/log/audit records administrative actions and configuration changes.
Conclusion:
Per F5-supported guidance, when suspecting power supply outages or chassis hardware issues, the BIG-IP Administrator should always check /var/log/ltm first.
質問 # 70
A user needs to determine known security vulnerabilities on an existing BIG-IP appliance and how to remediate these vulnerabilities. Which action should the BIG-IP Administrator recommend?
正解：B
解説：
F5 recommends using the iHealth diagnostic tool to identify security vulnerabilities and receive specific remediation guidance.
QKView and iHealth: A QKView file is a comprehensive diagnostic snapshot of the BIG-IP system. When this file is uploaded to the F5 iHealth portal, it is automatically parsed against a database of known issues and security advisories.
Vulnerability Diagnosis: The iHealth platform includes automated checks specifically designed to surface security gaps and "Heuristics" that match the system's current configuration and software version to known CVEs (Common Vulnerabilities and Exposures).
Remediation Guidance: For every identified vulnerability, iHealth provides direct links to the relevant F5 Security Advisory (K-article), which contains detailed remediation steps, such as specific software versions that contain a fix or temporary mitigation commands.
UCS vs. QKView: While a UCS (User Configuration Set) file is a backup of the system configuration, it is not the format used by the iHealth diagnostic engine for automated vulnerability scanning; the QKView is the required format for this process.
質問 # 71
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.
Evaluation of Other Options:
Disabled (Option A): If the VS were disabled, the configuration would typically show disabled or state down, and the symptoms would be similar, but the source filter is a more specific "misconfiguration" in this context.
Port 80 (Option C): The configuration destination 10.99.20.50:http explicitly confirms it is listening on port 80.
Unallowed Subnet: If a client from a different network (e.g., 10.10.1.5) tries to connect, the BIG-IP will silently drop the connection or send a reset because it does not match the defined source criteria.
