質問 # 33
A set of servers is used for an FTP application as well as an HTTP website via separate BIG-IP Pools. The server support team reports that some servers are receiving a lot more traffic than others. Which Load Balancing Method should the BIG-IP Administrator apply to even out the connection count?
正解：A
解説：
When load balancing is not working as expected across hardware hosting multiple services, the administrator must distinguish between "member" and "node" level algorithms102102102102. A "member" is a specific IP and port (e.g., 10.1.1.1:80), while a "node" is the physical server's IP (10.1.1.1) regardless of the port103. If servers host both FTP and HTTP services in separate pools, using "Least Connections (Member)" only balances connections within each individual pool. This can lead to a skewed distribution where one server is selected for a new HTTP connection because it has the fewest HTTP connections, even if it is currently overloaded with hundreds of FTP connections. By applying "Least Connections (Node)," the BIG-IP tracks the total number of connections to the physical hardware across all ports and pools106106106106. This ensures that the administrator can maintain an even distribution of the total workload across the server fleet, resolving the reports of uneven traffic distribution reported by the server support team

Without decrypting, what portion of an HTTPS session is visible with a packet capture? (Choose one answer)
正解：B
解説：
In an HTTPS session, the application-layer payload-including HTTP request headers, response headers, cookies, and body content-is encrypted using SSL/TLS. Without decrypting the traffic (for example, without SSL offloading on BIG-IP or access to the private keys), a packet capture cannot reveal any HTTP-level details.
However, network-layer and transport-layer information remains visible, even when encryption is used. This includes source and destination IP addresses, source and destination ports, TCP flags, sequence numbers, and TLS handshake metadata. Therefore, the source IP address (Option B) is visible in a packet capture of HTTPS traffic without decryption.
Options A, C, and D are incorrect because HTTP headers and cookies are part of the encrypted payload once HTTPS is established. BIG-IP troubleshooting documentation emphasizes this distinction when analyzing encrypted traffic flows using tcpdump, as administrators must rely on IP, port, and timing information unless SSL inspection or decryption is configured.
質問 # 35
Users are unable to reach an application. The BIG-IP Administrator checks the Configuration Utility and observes that the Virtual Server has a red diamond in front of the status. What is causing this issue?
正解：C
解説：
In the BIG-IP Configuration Utility, the status icon (shape and color) provides immediate feedback on why a virtual server is not working as expected81. A "Red Diamond" indicates that the object is "Offline" and unavailable to process traffic82. For a virtual server, this specific status typically means it has inherited an offline state from its mandatory backend resources8383. If all pool members associated with the virtual server have failed their health monitors, the virtual server will transition to a red diamond status because it has no healthy destination for incoming requests. This is distinct from a "Black Circle," which would indicate the virtual server has been manually "Disabled" by an administrator85858585. To troubleshoot a red diamond, the administrator must examine the associated pool and its members to determine why the health monitors are failing (e.g., server crashes, network path failures, or incorrect monitor strings). Resolving the health check failures on the pool members will return the virtual server to an "Available" (Green) status.
質問 # 36
Which tmsh command shows virtual server status?
正解：B
解説：
This command displays virtual server state, availability, and statistics.
質問 # 37
A BIG-IP Administrator plans to upgrade a BIG-IP device to the latest TMOS version.
Which two tools could the administrator leverage to verify known issues for the target versions? (Choose two answers)
正解：C、E
解説：
Before upgrading a BIG-IP system to a newer TMOS version, it is critical to review known issues to avoid introducing instability or regressions. F5 Bug Tracker (Option B) is a primary resource for this purpose. It allows administrators to search for documented software defects by TMOS version, module, symptom, or bug ID. Using Bug Tracker, an administrator can identify unresolved issues, fixed bugs, and behavioral changes that may affect their specific deployment, such as traffic handling, high availability, or module-specific functionality. This directly supports proactive troubleshooting and informed upgrade planning.
F5 iHealth (Option D) is another essential tool used during upgrade preparation. iHealth analyzes uploaded UCS or QKView files and correlates the device configuration and software version with F5's known issues database. It provides actionable reports highlighting critical defects, upgrade risks, interoperability concerns, and recommended target versions. iHealth is especially valuable because it contextualizes known issues based on the actual configuration running on the device.
The other options are not appropriate for verifying known software issues. F5 End User Diagnostics (Option A) is a client-side troubleshooting tool, F5 University (Option C) is a training platform, and F5 Downloads (Option E) is primarily used to obtain software images and release notes, not to analyze known defects in depth.
