NEW QUESTION # 48
What is the status of a pool member when manual resume is enabled and a health check first fails and then passes?
Answer: A
Explanation:
With manual resume enabled, BIG-IP does not automatically return a pool member to service after recovery. The member remains offline until manually re-enabled.
NEW QUESTION # 49
Refer to the exhibit.
A BIG-IP Administrator configures a Virtual Server to handle HTTPS traffic. Users report that the application is NOT working. Which additional configuration is required to resolve this issue?
Answer: C
Explanation:
According to the provided exhibit, the "SSL Profile (Client)" section in the Virtual Server configuration is empty. For a BIG-IP system to process HTTPS traffic, it must act as an SSL/TLS endpoint. This process, known as SSL Termination or SSL Offload, requires the assignment of a Client SSL Profile to the Virtual Server. Without this profile, the BIG-IP does not have the necessary certificate and private key information to perform the SSL handshake with the client's browser. Consequently, when a user attempts to connect via HTTPS, the TCP connection may establish, but the SSL handshake will fail because the BIG-IP will not know how to decrypt the incoming encrypted packets.
A Client SSL profile defines the ciphers, certificates, and keys that the BIG-IP uses to communicate securely with the client. In a standard HTTPS deployment, the BIG-IP decrypts the traffic and can then send it to the backend pool members either as plain text (header insertion/manipulation) or re-encrypt it using a Server SSL profile. While a Server SSL profile (Option C) is needed if the backend servers themselves require HTTPS, the initial failure for a user reaching a Virtual Server is almost always the lack of a Client SSL profile to terminate the user's connection. Changing the Service Port to HTTP (Option D) would be incorrect because the goal is to handle HTTPS traffic (typically port 443). Assigning the "clientssl" or a custom client-side profile from the "Available" list to the "Selected" list in the GUI is the mandatory step to make the Virtual Server operational for secure web traffic.
NEW QUESTION # 50
A BIG-IP Administrator is setting up a new BIG-IP device. The network administrator reports that the interface has an incompatible media speed. The BIG-IP Administrator needs to change this setting manually.
From which location should the BIG-IP Administrator perform this task?
Answer: A
Explanation:
Standard BIG-IP administration dictates that hardware-level physical attributes are managed within the Network section of the configuration. When a network switch and a BIG-IP fail to successfully negotiate speed and duplex settings (Auto-Negotiation), it can result in CRC errors, late collisions, or a total lack of link. To resolve this manually, the administrator must navigate to the Configuration Utility (GUI) and go to Network > Interfaces.
Within the Interfaces list, the administrator can select the specific physical port (e.g., 1.1 or 1.2) and modify its properties. By default, the media speed is set to "Auto," but the drop-down menu allows for manual selection of specific speeds (e.g., 100Mb/s, 1Gb/s, 10Gb/s) and duplex settings (Full or Half). While these changes can also be made via the TMOS Shell (TMSH) (Option B) using the modify net interface command, the question asks for the standard location, which in most administrative contexts refers to the primary GUI path. System > Configuration (Option D) is used for global device settings like NTP, DNS, and licensing, not for interface-specific physical layer parameters. The Front Console (Option A), referring to the LCD panel on physical appliances, is primarily used for initial management IP setup and viewing system alerts, but does not provide the granular interface configuration required for media speed adjustments.
NEW QUESTION # 51
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? (Choose one answer)
Answer: A
Explanation:
SSH is a Layer 4 TCP-based protocol that operates on TCP port 22 and does not use HTTP in any capacity. In the exhibit, the Virtual Server is configured with an HTTP Profile applied, which is inappropriate for SSH traffic and causes connection failures.
According to the BIG-IP Administration: Data Plane Configuration documentation:
An HTTP profile must only be applied to Virtual Servers handling HTTP or HTTPS traffic.
When an HTTP profile is attached, BIG-IP expects HTTP headers and attempts to parse application-layer data.
Non-HTTP protocols such as SSH, FTP (control), SMTP, and other raw TCP services will fail if an HTTP profile is enabled.
Why the other options are incorrect:
A . Set Protocol to UDP
SSH uses TCP, not UDP. Changing the protocol would break SSH entirely.
B . Set Source Address to 10.1.1.2
The source address setting controls client access restrictions and is unrelated to protocol parsing issues.
C . Set Destination Address/Mask to 0.0.0.0/0
The destination address is already valid for a specific SSH service and does not impact protocol handling.
Correct Resolution:
The BIG-IP Administrator should remove the HTTP Profile (set it to None) so the Virtual Server functions as a pure Layer 4 TCP service, allowing SSH connections to pass through successfully.
NEW QUESTION # 52
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?
Answer: C
Explanation:
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.
