질문 # 84
The BIG-IP Administrator has configured an HTTP health monitor applied to a Pool of HTTP web servers hosting www.f5.com, but all Pool Members show a DOWN status. The web server is returning a response of '
400 Bad Request ' . What would be the correct monitor Send string?
정답：C
설명：
A 400 Bad Request response from an HTTP/1.1 web server is a definitive indicator that the HTTP request sent by the health monitor is missing a required Host header . In HTTP/1.1, the Host header is mandatory per RFC 7230. Web servers - particularly those hosting named virtual hosts such as www.f5.com - will reject any HTTP/1.1 request that omits the Host header, returning a 400 error, which the BIG-IP monitor interprets as a failed health check, marking all members DOWN.
The correct Send string must include:
* The GET request line with HTTP/1.1 protocol declaration
* A \r\n (carriage return + line feed) after the request line
* The Host: www.f5.com header to satisfy HTTP/1.1 requirements
* A \r\n after the Host header
* Connection: Close header to instruct the server to close the connection after responding
* A final \r\n\r\n to properly terminate the HTTP request headers
Only option C satisfies all these requirements with the correct syntax and Host header inclusion.
Option D (the current configured string) omits the Host header entirely - the root cause of the 400 error.
Options A and B are structurally incomplete or syntactically malformed.

질문 # 85
A configuration change is made on the standby member of a device group. What is displayed as
"Recommended Action" on the Device Management Overview screen?
정답：B
설명：
The BIG-IP system uses a centralized management framework to ensure that all devices within a Sync- Failover group share a consistent configuration. When an administrator makes a change on any member of the group-whether it is the active or the standby device-the system detects a "ConfigSync" mismatch. The
"Device Management >> Overview" screen tracks these changes by comparing the commit ID and timestamps of the configurations across all peers.
If a change is made on the standby member, that device now possesses a more recent configuration than the other members of the group. Consequently, the BIG-IP GUI will display a status of "Changes Pending" and suggest a Recommended Action to resolve the discrepancy. In this scenario, the correct action is to Synchronize the standby member configuration to the group. This push operation will copy the updated configuration from the standby device to the active device (and any other peers), bringing the entire cluster back into a "In Sync" status. It is important to note that BIG-IP allows bi-directional synchronization; you do not have to be on the active device to push a configuration. However, administrators must be cautious:
choosing Option C (Synchronizing the active member to the group) would overwrite the changes just made on the standby device with the older configuration from the active device, effectively reverting the changes. The Recommended Action always points toward the direction that propagates the most recent change to the rest of the group.
질문 # 86
Users are unable to reach an application. The Virtual Server shows a red diamond status in the Configuration Utility.
What is the cause?
정답：A
설명：
A red diamond indicates the Virtual Server is enabled but unavailable due to all pool members being down.
질문 # 87
The BIG-IP Administrator has to provide encrypted communication between users and the virtual server they access. Multiple hostnames are configured in DNS with the same IP address.
Which profile type and setting in the profile should be used? (Choose one answer)
정답：A
설명：
When multiple hostnames resolve to the same IP address and encrypted communication is required, the BIG- IP must be able to present the correct SSL certificate based on the hostname requested by the client. This is accomplished using Server Name Indication (SNI).
According to BIG-IP Administration: Data Plane Configuration documentation:
* SNI is a client-side TLS extension, where the client includes the requested hostname during the SSL handshake.
* BIG-IP evaluates this hostname using the Client SSL profile, not the Server SSL profile.
* The "Server Name" setting in the Client SSL profile enables BIG-IP to select the appropriate SSL certificate for the requested hostname.
Why option C is correct:
* Client SSL profile handles inbound (client-side) encryption.
* Server Name enables SNI-based certificate selection when multiple DNS names share the same virtual server IP.
Why the other options are incorrect:
* A. Client SSL, Client NameThere is no Client SSL setting called Client Name for SNI certificate selection.
* B. Server SSL, Server NameServer SSL is used for encryption between BIG-IP and backend servers, not for client-side hostname identification.
* D. Server SSL, Client NameServer SSL does not process client-requested hostnames during TLS negotiation.
Correct Resolution:
Configure a Client SSL profile and enable the Server Name (SNI) setting to support multiple encrypted hostnames on the same virtual server IP.
질문 # 88
Refer to the exhibit.
A BIG-IP Administrator needs to configure health monitors for a newly configured server pool named Pool_B.
Which health monitor settings will ensure that all pool members will be accurately marked as available or unavailable? (Choose one answer)
정답：D
설명：
From the exhibit, the pool contains different applications on different service ports (for example, HTTP/80, FTP/21, HTTPS/443, SSH/22). To mark pool members correctly, BIG-IP must be able to verify the actual service running on each member's port.
In BIG-IP Administration: Data Plane Configuration, monitor behavior is described as follows:
When multiple monitors are assigned to a pool, the Availability Requirement controls how monitor results are evaluated:
At least one = the pool member is marked up if any one of the assigned monitors succeeds.
All = the pool member is marked up only if every assigned monitor succeeds.
For pools containing members with different services/ports, using All can incorrectly mark members down because monitors intended for other services will fail on the wrong port.
Why C is correct:
Assigning HTTPS, HTTP, FTP, and SSH covers the actual services shown in the pool.
Setting the Availability Requirement to at least one ensures that each pool member is considered available when its appropriate service monitor succeeds, without being forced to pass unrelated service monitors.
Why the other options are incorrect:
A / D (Availability Requirement = all): would cause members to be marked down when unrelated monitors fail (e.g., SSH monitor against an HTTP member).
B (includes ICMP): ICMP can indicate the host is reachable even if the application service is down, which does not "accurately" reflect service availability.
Therefore, the best choice is HTTPS, HTTP, FTP, and SSH with Availability Requirement of at least one health monitor.
