質問 # 23
A BIG-IP Administrator needs to view the CPU utilization of a particular Virtual Server. Which section of the Configuration Utility should the administrator use for this purpose?
正解：D
解説：
When a BIG-IP system experiences high overall CPU usage, troubleshooting requires identifying which specific application or service is the primary consumer of resources. While the system-wide performance graphs provide a global view, the granular data necessary to isolate a "top talker" is found in the "Local Traffic" statistics. Navigating to Statistics > Module Statistics > Local Traffic > Virtual Servers allows the administrator to see specific metrics for each configured virtual server, including the number of packets processed, current connections, and critical CPU cycles consumed. This is essential for troubleshooting performance issues where an inefficient iRule, high SSL handshake volume, or complex L7 profiles (like Compression or ASM) might be overtaxing the Traffic Management Microkernel (TMM) for one specific application. By reviewing these basic stats, an administrator can determine if a performance bottle-neck is a system-wide h1ardware issue or if it is isolated to a single virtual server, enabling targeted remediation such as optimizing iRule logic or moving the high-load virtual server to a dedicated device.
質問 # 24
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：D
解説：
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 Server. 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 connections. To fix this, the administrator must set the HTTP profile to "None". 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 # 25
Where should the BIG-IP Administrator go in the GUI to verify the status of pool members of a pool?
正解：D
解説：
To verify the specific health and availability status of individual members within a specific pool, the administrator must navigate to the Members tab of that specific pool.
* Navigation Path: The correct path is Local Traffic > Pools > Pool List, then clicking on the name of the <pool_in_question>, and finally selecting the Members tab. This screen provides a granular view of each member's IP address, port, and their current status (indicated by the colored icons: Green, Red, Yellow, or Blue).
* Why Option A is correct: While you can see a general status summary on the Pool List page (Option B), that page only shows the status of the pool as a whole. To troubleshoot why a pool is not working or to see which specific member is down, you must drill down into the Members tab.
* Evaluation of Other Options:
* Local Traffic -> Pools (Option B): This leads to the Pool List. It shows the aggregate status of all pools but does not list individual member details or their specific monitor results without further clicking.
* Local Traffic -> Virtual Servers -> Statistics (Option C): This path shows traffic statistics (bits in/out, connections) for virtual servers, not the health monitor status of individual pool members.
* Local Traffic -> Nodes (Option D): While this shows the health of the underlying IP address (Node), it does not show the status of the specific service (Port/Member) within a pool. A Node might be "Up" (ICMP), while the Pool Member is "Down" (HTTP failure).

正解：A、D
質問 # 27
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：C
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.
