NEW QUESTION # 83
Refer to the exhibit.
A BIG-IP Administrator configures a new VLAN on an HA pair of devices that does NOT yet have any traffic. This action causes the assigned traffic group to fail over to the standby device. Which VLAN setting should be changed to prevent this issue?
Answer: A
Explanation:
The exhibit shows the advanced configuration of a VLAN where the Fail-safe option is checked. VLAN Fail- safe is a high-availability feature used to monitor network connectivity on a specific VLAN. When enabled, the BIG-IP system monitors the VLAN for network traffic. If the system does not detect any " useful " traffic on the VLAN within the specified Fail-safe Timeout (which is 90 seconds in the exhibit), it attempts to generate traffic by pinging the default gateway or other devices. If it still detects no traffic, the BIG-IP concludes that the VLAN is unreachable or the network interface has failed, and it triggers a " Fail-safe Action " -in this case, " Reboot " or a failover to the peer device in the HA group.
Because the administrator has just created a new VLAN that " does NOT yet have any traffic, " the Fail-safe mechanism triggers immediately after the 90-second timeout period. Since no devices are yet communicating on this VLAN, the BIG-IP incorrectly assumes there is a hardware or cabling failure and forces a failover to ensure the standby device (which might have better connectivity) takes over. To prevent this unwanted failover, the administrator should uncheck the Fail-safe box for that specific VLAN until the VLAN is fully populated with active nodes and regular traffic. Once the application is live and traffic is flowing, Fail-safe can be re-enabled to provide an additional layer of redundancy. Auto Last Hop (Option A) and Source Check (Option B) are routing and security features that do not trigger HA failover events.
NEW QUESTION # 84
Exhibit:
Due to a change in application requirements, a BIG-IP Administrator needs to modify the configuration of a Virtual Server to include a Fallback Persistence Profile. Which persistence profile type should the BIG-IP Administrator use for this purpose?
Answer: C
Explanation:
In a BIG-IP environment, a Fallback Persistence Profile is utilized as a secondary " stickiness " mechanism when the primary (Default) persistence method fails to provide a valid persistence record. For example, if a Virtual Server uses HTTP Cookie Persistence as its primary method, but a client's browser has cookies disabled, the BIG-IP will be unable to find a persistence cookie in the request. Without a fallback method, the system would treat every request from that client as a new, independent connection, potentially breaking the application session.
Source Address Affinity (also known as Source Address Persistence) is the most common and standard choice for a fallback profile. It operates at the network layer (Layer 3) by tracking the client's source IP address.
Because every IP packet contains a source address, this method is virtually guaranteed to work even when application-layer data (like Cookies or SSL Session IDs) is missing or encrypted beyond the BIG-IP ' s visibility. While Universal (Option A) and Hash (Option D) profiles are highly flexible and can use iRules to persist on almost any data, they require specific configuration and logic that may not always be present or valid. SSL persistence (Option C) relies on the SSL Session ID, which frequently changes due to modern browser security practices (session renegotiation), making it less reliable than Source Address Affinity. By configuring Source Address Affinity as the fallback, the administrator ensures that the BIG-IP has a " safety net " to maintain session integrity based on the client ' s IP address when the more granular cookie-based persistence is unavailable.
NEW QUESTION # 85
A BIG-IP Administrator is creating a new Trunk on the BIG-IP device. What objects should be added to the new Trunk being created?
Answer: C
Explanation:
In F5 BIG-IP architecture, a Trunk is a logical aggregation of physical interfaces designed to increase bandwidth and provide link redundancy through 802.3ad Link Aggregation Control Protocol (LACP).
When creating a Trunk object within the BIG-IP configuration, the administrator must assign physical Interfaces to it - these are the underlying hardware ports (e.g., 1.1, 1.2, 1.3) that will be bundled together to form the aggregated logical link.
It is critical to understand the layered object hierarchy on the BIG-IP platform:
* Interfaces # assigned to Trunks
* Trunks (or individual Interfaces) # assigned to VLANs (as tagged or untagged members)
* VLANs # assigned Self IP addresses
* Self IPs / Routes # configured at the network layer above
VLANs are not added to a Trunk; rather, a Trunk is added as a member of a VLAN. IP addresses and network routes are configured independently at a higher abstraction layer and have no direct association with Trunk creation.
This layered design ensures proper separation of concerns across the data plane. Misunderstanding this hierarchy is a common configuration error that can result in traffic forwarding failures.

NEW QUESTION # 86
A BIG-IP Administrator creates an HTTP Virtual Server using an iApp template. After the Virtual Server is created, the user requests to change the destination IP addresses. The BIG-IP Administrator tries to change the destination IP address from 10.1.1.1 to 10.2.1.1 in Virtual Server settings, but receives the following error: " The application service must be updated using an application management interface. " What is causing this error?
Answer: B
Explanation:
In F5 BIG-IP administration, iApps are designed to manage complex application configurations as a single unit. When an iApp is deployed, it creates an " Application Service " object that owns all the associated LTM objects, such as Virtual Servers, Pools, and Nodes. By default, these iApps are created with Strict Updates enabled. Strict Updates is a safety mechanism that prevents administrators from making manual " out-of-band
" changes to the individual objects created by the iApp. The system enforces this because manual changes would be overwritten the next time the iApp template is updated or re-entered.
When the administrator attempts to change the destination IP address directly on the Virtual Server object, the BIG-IP system checks the " Strict Updates " flag. If it is set to " Enabled, " the system blocks the modification and generates the error message stating the service must be updated via the application management interface.
To resolve this, the administrator must navigate to the iApp > > Application Services menu, select the specific application service, and go to the " Reconfigure " tab. Within the iApp configuration form, the destination IP can be safely changed. Alternatively, if the administrator specifically wants to manage the objects manually and forgo the benefits of the iApp template management, they could disable " Strict Updates " in the iApp properties, though this is generally discouraged as it breaks the template ' s logic. The error is not related to subnetting or duplicate IPs, but strictly to the configuration authority assigned to the iApp service.
NEW QUESTION # 87
DNS queries from internal DNS servers fail when sent through a BIG-IP Virtual Server.
Which Virtual Server property should be changed?
Answer: A
Explanation:
Standard DNS queries use UDP. Configuring the Virtual Server for TCP causes DNS traffic to fail.
