質問 # 68
A BIG-IP Administrator notices that one of the servers that runs an application isNOTreceiving any traffic.
The BIG-IP Administrator examines the configuration status of the application and observes the displayed monitor configuration and affected pool member status.
What is the possible cause of this issue? (Choose one answer)
正解：C
解説：
The key clue in the exhibit is the pool member's availability showing"Offline (Enabled) - Parent down". In BIG-IP terminology, a pool member inherits the status of itsparent node. If thenodeis marked down (for example, by a node-level monitor or a default "node is down" condition), thenall pool members using that node IPwill also be marked down and will not receive any traffic, even if the application service on the member port might be healthy.
While the HTTPS monitor configuration (send/receive strings) is displayed, the statusspecificallyindicates anode (parent) failure, not a service-level failure. If the problem were the application not matching the receive string, you would typically see the member down due to themember's monitorfailing (and the status would reflect monitor failure details), rather than "parent down." Option D is too broad; BIG-IP can generally reach the subnet (other servers work), and this symptom points to a specific node condition. Option C is incorrect because HTTP/1.1 is commonly used for monitoring and is valid when properly formatted (especially with a Host header). Therefore, the most likely cause is that thenode health monitor is not responding, causing the node-and consequently the member-to be marked down.
質問 # 69
A device group is currently in theChanges Pendingsync status. How can the BIG-IP Administrator determine which member of the device group has the most recent configuration? (Choose one answer)
正解：C
解説：
When a BIG-IP device group shows a Changes Pending status, it indicates that one or more devices in the group have configuration changes that have not yet been synchronized to the other members. To identifywhich device has the most recent (authoritative) configuration, the administrator must view the detailed synchronization status at thedevice group level.
The correct location is Device Management > Device Groups (Option D). Within this menu, the BIG-IP Configuration Utility displays each device group along with its synchronization status and provides details about which device has pending changes. From this view, the administrator can clearly see which device is marked as havingchanges pending, making it the source device that should be used to initiate a Sync to Groupoperation.
質問 # 70
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：C
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.
質問 # 71
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 # 72
Refer to the exhibit.
A user with IP address 192.168.162.70 is unable to connect to an HTTP application. What is a possible cause within the Virtual Server configuration?
正解：C
解説：
The failure to connect is caused by a restrictive Source Address filter configured on the Virtual Server.
* Source Address Filtering: In the BIG-IP system, the Source Address field on a Virtual Server acts as an implicit Access Control List (ACL). Only traffic originating from a client IP address that matches the specified network range will be accepted and processed by the Virtual Server.
* Analyzing the Exhibit: The provided configuration for vs_http shows the Source Address is set to
10.128.10.0/24. This means the Virtual Server will only accept connections from the subnet ranging from 10.128.10.1 to 10.128.10.254.
* Identifying the Conflict: The user trying to connect has the IP address 192.168.162.70. Since
192.168.162.70 does not fall within the allowed 10.128.10.0/24 range, the BIG-IP system will not match this traffic to the Virtual Server, effectively blocking the connection attempt.
* Evaluation of Other Options:
* All Ports (Option A): Configuring a Virtual Server for "All Ports" (port 0) allows it to handle traffic for any destination port, which would not block a standard HTTP application.
* Destination Address (Option B): The destination address 192.168.162.80 is the Virtual IP (VIP) users should be connecting to; this is a standard configuration and not the cause of the failure for a user reaching out to it.
* Standard Type (Option C): A "Standard" Virtual Server is the most common type used for HTTP applications as it allows for Layer 7 profiles and full proxy capabilities.
