質問 # 34
A BIG-IP Administrator needs to collect HTTP status code and HTTP method for traffic flowing through a virtual server. Which default profile provides this information?
正解：A
解説：
To gather granular Layer 7 data such as specific HTTP methods (GET, POST, etc.) and HTTP status codes (200, 404, 500), the BIG-IP system utilizes the Analytics (AVR) profile.
* Analytics Profile (Application Visibility and Reporting): While a standard HTTP profile tracks basic byte counts and requests, the Analytics profile is designed specifically to capture, analyze, and display detailed application performance metrics.
* Metrics Captured: When attached to a virtual server, it records URL-level statistics, response codes, page load times, and client-side metrics.
* Why not others? * HTTP Profile (Option A): This profile handles the parsing of HTTP traffic but does not provide a built-in reporting dashboard for status code distribution.
* Statistics Profile (Option C): This is a legacy profile used for custom user-defined counters and does not automatically categorize HTTP methods or status codes.
* Request Adapt (Option D): This is used for integrating with ICAP servers (like virus scanners) and does not perform traffic reporting.

Pool /Common/testpool member /Common/10.120.0.5:8090 monitor status down. [ /Common/http: up, /Common/http2: down; last error: ] [ was up for lhr:0min:43sec ] Why is this pool member being marked down?
正解：D
解説：
This log entry indicates that multiple monitors are assigned to the pool member, and the member is failing one of them.
Understanding Monitor Logic: By default, if multiple monitors are assigned to a pool or pool member without a "Minimum To Up" (Availability Requirement) setting, the system requires all monitors to pass for the member to be marked "Up".
Analyzing the Log: The log clearly states: [ /Common/http: up, /Common/http2: down; ... ]. This means the standard HTTP monitor is successful, indicating the member is serving HTTP traffic, but the http2 monitor has failed.
Conclusion: Since the http monitor is "up" but the member as a whole is "down," we can conclude the member is successfully responding to standard HTTP requests but not HTTP2 requests. Therefore, the member is currently only serving standard HTTP traffic.
質問 # 36
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 # 37
A BIG-IP Administrator configured a virtual server with a pool of 3 members and selected the Round Robin load balancing method to evenly distribute traffic across the pool members. During initial testing, the virtual server failed to respond to http requests.
Plaintext
ltm virtual http.vs {
destination 10.10.1.100:http
ip-protocol tcp
mask 255.255.255.255
pool http.pool
profiles {
tcp{}
}
serverssl-use-sni disabled
source 0.0.0.0/0
translate-address enabled
translate-port enabled
}
ltm pool http_pool {
members {
10.10.1.101:http {
address 10.10.1.101
session monitor-enabled
state checking
}
10.10.1.102:http {
address 10.10.1.102
session monitor-enabled
state checking
}
}
monitor tcp
}
What configuration change on the BIG-IP will resolve this issue?
正解：B
解説：
The issue described is a classic case of asymmetric routing in a "one-arm" or same-subnet topology.
* Symptom Analysis: The Virtual Server (10.10.1.100) and the pool members (10.10.1.101 and
10.10.1.102) are on the same subnet.
* The Problem: When a client sends a request to the VIP, the BIG-IP translates the destination IP but keeps the client's original source IP. The server receives the packet and sees a source IP from a different subnet. Instead of sending the response back to the BIG-IP, the server sends it directly to its default gateway. The client receives a response from the server's IP, which it doesn't recognize, causing the connection to fail.
* The Solution: Enabling SNAT Auto Map ensures the BIG-IP changes the source IP of the packet to its own self-IP. This forces the pool member to send the response back to the BIG-IP, which then translates it correctly and sends it to the client.
* Incorrect Options: Adding an HTTP profile (Option B) or an HTTP monitor (Option C) would enhance the configuration but would not fix the underlying Layer 3 routing issue causing the traffic drop.
質問 # 38
A pool member is exhibiting frequent up-and-down state changes, leading the BIG-IP Administrator to suspect a health monitor issue. Which specific log file should the BIG-IP Administrator review to diagnose the problem?
正解：D
解説：
The Local Traffic Manager (LTM) log file is the primary repository for all events related to load balancing objects, including virtual servers, pools, and nodes.
* Monitor Logging: When a health monitor marks a pool member as "UP" or "DOWN," the system generates a log entry in /var/log/ltm.
* Diagnosing Flaps: To troubleshoot "flapping" (frequent state changes), an administrator would look for messages like 01010028:3: Pool /Common/http_pool member /Common/10.10.1.1:80 monitor status down followed quickly by an "up" status. This log provides the timestamp and the specific monitor that triggered the state change.
