NEW QUESTION # 87
All pool members are online. All other virtual server settings are at default.
What might alter the load balancing behavior? (Choose one answer)
Answer: B
Explanation:
By default, BIG-IP load balancing algorithms (such as Round Robin) distribute connections evenly across all available pool members. However, persistence profiles override normal load balancing decisions by forcing subsequent connections from a client to be sent to the same pool member.
According to the BIG-IP Administration: Data Plane Configuration documentation:
* Persistence creates a client-to-server mapping that is honored before load balancing algorithms are applied.
* When persistence is enabled, BIG-IP may repeatedly select the same pool member even if others are available.
* This directly alters load balancing behavior.
Why the other options are incorrect:
* A. Adding a OneConnect profileOneConnect optimizes server-side TCP connections but does not change which pool member is selected.
* B. Enabling SNAT automapSNAT affects source address translation, not pool member selection.
* C. Enabling a fallback host in the HTTP profileA fallback host is only used when no pool members are available.
Correct Resolution:
Adding a persistence profile alters load balancing behavior by maintaining client affinity to a specific pool member.
NEW QUESTION # 88
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 UDPSSH uses TCP, not UDP. Changing the protocol would break SSH entirely.
B). Set Source Address to 10.1.1.2The source address setting controls client access restrictions and is unrelated to protocol parsing issues.
C). Set Destination Address/Mask to 0.0.0.0/0The 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 # 89
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: D
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 # 90
A BIG-IP Administrator configures a Virtual Server to load balance traffic between 50 webservers for an ecommerce website. Traffic is being load balanced using the Least Connections (node) method. The webserver administrators report that customers are losing the contents from their shopping carts and are unable to complete their orders. What should the BIG-IP Administrator do to resolve the issue?
Answer: B
Explanation:
The issue of "lost shopping carts" in an ecommerce environment is a classic symptom of a missing or improperly configured Persistence Profile. In modern web applications, session data-such as items added to a cart-is often stored locally on the specific web server that initially handled the user's request. If the BIG-IP system load balances a user's subsequent request (like clicking "Checkout") to a different server among the 50 webservers, the new server will not have the session data, and the user will appear to have an empty cart.
While Least Connections (node) is an efficient load balancing algorithm, it makes a new decision for every connection unless persistence is enabled. To resolve this, the administrator must implement a persistence mechanism. HTTP Cookie Persistence (Option A) is the industry standard for web applications. By assigning a cookie persistence profile to the Virtual Server, the BIG-IP inserts a unique cookie into the HTTP response.
When the user's browser returns that cookie in future requests, the BIG-IP identifies the specific server that handled the first request and consistently directs the user back to that same server for the duration of their session.
Sip_info (Option B) is a persistence method for VOIP traffic and is not applicable to web traffic. Ratio load balancing (Options C and D) merely changes the distribution frequency but still does not guarantee that a specific user will stay on the same server across multiple requests. Therefore, adding a cookie persistence profile is the direct procedural fix to maintain session state and ensure ecommerce functionality.
NEW QUESTION # 91
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: D
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.
