質問 # 42
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：
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 # 43
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.
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? (Choose one answer)
正解：C
解説：
This virtual server is intended to function as a forwarding (IP-forwarding) virtual server, which is commonly used for routing or firewall-style deployments where BIG-IP forwards traffic transparently without load balancing or address translation. For a forwarding virtual server to match and pass all traffic, the destination must be configured as 0.0.0.0:any with a mask of 0.0.0.0, not 255.255.255.255.
The configured mask 255.255.255.255 represents a /32 host mask, which restricts the virtual server to matching traffic destined only for the exact IP address 0.0.0.0. Since 0.0.0.0 is not a valid routable destination for normal traffic, no packets will ever match the virtual server, causing it to pass no traffic at all.
This is a well-documented BIG-IP behavior:
destination 0.0.0.0:any
mask 0.0.0.0
together define a catch-all forwarding virtual server.
The destination itself (Option A) is correct for a forwarding VS, and disabling address translation (Option C) is expected and required for IP-forwarding mode. Therefore, the incorrect subnet mask is the sole reason the virtual server is not functioning as expected.
質問 # 44
Refer to the exhibit. A BIG-IP Administrator creates a new Virtual Server to load balance SSH traffic. Users are unable to log on to the servers. What should the BIG-IP Administrator do to resolve the issue? (Exhibit shows a Standard Virtual Server with an HTTP profile applied).
正解：C
解説：
Comprehensive and Detailed Explanation From BIG-IP Administration Supp13ort and Troubleshooting documents: When troubleshooting a Virtual Server that is not working as expected, it is critical to ensure that the applied profiles match the type of traffic being processed. SSH (Secure Shell) is a non-HTTP protocol that operates over TCP. The exhibit indicates that an HTTP profile is applied to the Virtual Server14. An HTTP profile instructs the BIG-IP system to parse traffic as HTTP; however, since SSH traffic does not follow HTTP specifications, the BIG-IP's parser will fail to understand the data stream, typically resulting in dropped packets or reset connections15. To fix this, the administrator must set the HTTP profile to "None"16. This allows the Virtual Server to act as a "Standard" or "FastL4" listener that passes the encrypted SSH data transparently to the backend pool members without attempting application-layer inspection. This highlights a common troubleshooting step: verifying that L7 profiles are not inadvertently applied to L4 traffic, which disrupts the expected traffic flow between the client and the server.
質問 # 45
Which two methods should the BIG-IP Administrator troubleshoot a Pool-member that's been marked
"DOWN" by its Health Monitor? (Pick the 2 correct responses below)
正解：B、D
解説：
When a health monitor marks a member "Down," the goal is to determine if the issue is at the network level or the application level.
* Monitor Logging (Option A): In the Pool Member configuration, an administrator can enable
"Monitor Logging". This generates a detailed text file in /var/log/monitors/ that shows the exact "Send" string sent by the BIG-IP and the exact "Receive" string (or lack thereof) returned by the server.
* TCPdump (Option C): This is the most definitive way to see if the monitor traffic is even leaving the BIG-IP and if the server is responding with a TCP RST (reset) or an ICMP unreachable message. A command such as tcpdump -ni <vlan> host <member_ip> and port <member_port> is standard for this task.
* Why not others? While the routing table (Option B) is useful for general connectivity, if other members in the same subnet are "Up," the routing is likely fine. Statistics (Option D) show that it is down but rarely why it is down at a protocol level.
質問 # 46
Due to a change in application requirements, a BIG-IP Administrator needs to modify the configuration of a Virtual Server to include a Fallback Persistence Profile. Which persistence profile type should the BIG-IP Administrator use for this purpose?
正解：C
