質問 # 31
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：B
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 # 32
an existing, highly utilized pool. Soon after, there are reports that the application is failing to load for some users. What pool level setting should the BIG-IP Administrator check?
正解：B
解説：
When a pool is not working as expected immediately after adding new members to a busy environment, the "Slow Ramp Time" setting is a critical factor
. In a pool using the "Least Connections" load balancing method, a new member starts with zero active connections5858. Without a slow ramp time, the BIG-IP will immediately direct a high volume of new traffic to this server to "equalize" it with other members. This sudden surge can overwhelm the server's application stack before it has fully initialized or warmed its caches, leading to failures. By configuring a "Slow Ramp Time," the administrator ensures that the system gradually increases the amount of traffic sent to the new member over a specified duration. The traffic sent is proportional to the time the member has been available relative to the ramp time setting62. If the application fails only for users routed to new servers, reviewing this setting helps ensure that new capacity is integrated into the pool without disrupting service performance
質問 # 33
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.

ltm virtual http.vs {
destination 10.10.1.100:http
ip-protocol tcp
mask 255.255.255.255
pool http.pool

}
serverssl-use-sni disabled
source 0.0.0.0/0

}
ltm pool http_pool {

}
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：A
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 # 34
A BIG-IP device sends out the following SNMP trap: big-ipo.f5.com - bigipExternalLinkChange Link: 1.0 is DOWN. Where in the BIG-IP Configuration utility should the BIG-IP Administrator verify the current status of Link 1.0?
正解：B
解説：
Comprehensive and Detailed Explanation From BIG-IP Administration Support and Troubleshooting documents:Identifying network-level performance issues often starts with investigating hardware-level alerts78. In F5 terminology, a "Link" like "1.0" or "1.1" refers to a physical interface on the appliance79.
When an SNMP trap reports that a link is "DOWN," it indicates a loss of signal or an administrative shutdown of the physical port80. To verify this, the administrator must navigate to Network > Interfaces > Interface List81. This screen provides real-time status, showing whether the interface is "up," "down," or
"uninitialized," as well as any media speed or duplex mismatches that could be causing performance degradation82. Troubleshooting this is the first step in resolving "pool member down" or "VLAN failsafe" issues, as a down interface will take down any VLANs associated with it, immediately halting all traffic flow for the services relying on that physical path.
質問 # 35
Refer to the exhibit.
A BIG-IP Administrator needs to deploy an application on the BIG-IP system to performSSL offload and re- encrypt the traffic to pool members. During testing, users are unable to connect to the application.
What must the BIG-IP Administrator do to resolve the issue? (Choose one answer)
正解：D
解説：
To successfully performSSL offload and re-encryptionon a BIG-IP system, the virtual server must be configured withboth a Client SSL profile and a Server SSL profile. The Client SSL profile enables BIG-IP to decrypt inbound HTTPS traffic from clients, while the Server SSL profile is required tore-encrypt traffic before forwarding it to the pool members.
From the exhibit, the virtual server has aClient SSL profile configured, which allows BIG-IP to accept HTTPS connections from clients. However, there isno Server SSL profile attached, meaning BIG-IP attempts to sendunencrypted HTTP trafficto pool members listening on HTTPS (port 443). This protocol mismatch causes the server-side SSL handshake to fail, resulting in users being unable to connect to the application.
This behavior is well documented in BIG-IP SSL troubleshooting guides: when backend servers expect HTTPS, a Server SSL profile is mandatory to establish a secure connection from BIG-IP to the pool members.
The other options are incorrect:
* Removing the Client SSL profile (Option A) would break client-side HTTPS.
* The server-side TCP profile (Option B) is unrelated to SSL encryption.
* Forward Proxy (Option C) is only used for outbound SSL inspection scenarios.
Therefore, configuring anSSL Profile (Server)is the correct and required solution.
