NEW QUESTION # 13
Refer to the exhibit.
DNS queries from two internal DNS servers are being load-balanced to external DNS servers via a virtual server on a BIG-IP device. The DNS queries originate from:
192.168.10.100
192.168.10.200
and target:
192.168.2.150
All DNS queries destined for the external DNS servers fail.
Which property change should the BIG-IP Administrator make in the Virtual Server to resolve this issue? (Choose one answer)
Answer: A
Explanation:
DNS traffic is primarily transported using UDP port 53. In the exhibit, the Virtual Server is configured with the Protocol set to TCP, which prevents standard DNS queries from being processed correctly. BIG-IP Virtual Servers must be configured with the correct Layer 4 protocol to match the application traffic they are handling.
According to the BIG-IP Administration: Data Plane Configuration documentation:
The Protocol setting on a Virtual Server defines whether traffic is processed as TCP, UDP, or another supported transport protocol.
Standard DNS queries and responses use UDP, while TCP is only required for DNS zone transfers (AXFR) or exceptionally large responses.
When a DNS Virtual Server is incorrectly configured with TCP, UDP-based DNS queries are dropped, causing all requests to fail.
Why the other options are incorrect:
A . Protocol profile (Client) to DNS_OPTIMIZED
A DNS profile enhances DNS functionality but does not correct an incorrect transport protocol configuration.
B . Type to Performance (HTTP)
Performance (HTTP) Virtual Servers are designed for HTTP traffic and are not suitable for DNS services.
C . Source Address to 192.168.10.0/24
The existing source IPs already fall within the allowed range, so this setting does not address the failure.
Correct Resolution:
Changing the Protocol to UDP aligns the Virtual Server with standard DNS transport requirements, allowing DNS queries to be successfully processed and load-balanced.
NEW QUESTION # 14
In a pool there are 2 pool members (older servers) that can handle fewer connections than the other 3 newer servers.
Which load balancing method would allow more traffic to be directed to the newer servers? (Choose one answer)
Answer: B
Explanation:
This scenario requires unequal load distribution based on server capacity. The newer servers must receive more connections than the older ones, while still dynamically accounting for active connection counts.
According to BIG-IP Administration: Data Plane Configuration documentation:
Weighted Least Connections (member) combines:
Connection awareness (least connections)
Administrator-defined weights (ratios) to reflect server capacity
Pool members with higher weights receive proportionally more new connections than members with lower weights, even when using the same load balancing algorithm.
Why B is correct:
Allows assigning higher weights to newer servers and lower weights to older servers Ensures smarter traffic distribution based on both capacity and real-time load Why the other options are incorrect:
A). Global AvailabilityUsed for disaster recovery and site failover, not intra-pool load distribution.
C). Round RobinDistributes connections evenly without considering server capacity.
D). Least Connections (member)Balances only by current connection count and does not account for differences in server performance or capacity.
Correct Resolution:
Use Weighted Least Connections (member) and assign higher weights to newer servers so they receive more traffic while protecting older servers from overload.
NEW QUESTION # 15
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)
Answer: A
Explanation:
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.
NEW QUESTION # 16
Application administrators are reporting that nodes different from those configured in the pool are selected.
The use of an iRule is suspected. How can the BIG-IP Administrator check if an iRule is used for this traffic?
(Pick the 2 correct responses below)
Answer: A,D
Explanation:
To determine if an iRule is influencing traffic for a specific Virtual Server, the administrator must verify the association between the Virtual Server object and any applied scripts. In the BIG-IP Configuration Utility (GUI), this association is found under the Resources tab of the specific Virtual Server. While there is an
"iRules" sub-menu under Local Traffic, checking the Virtual Server's Resources tab is the definitive way to see which specific rules are currently active and in what order they are being processed for that particular traffic flow.
From the Command Line Interface (CLI), the tmsh list /ltm virtual <virtual_server> command provides a full text-based output of the virtual server's configuration. If iRules are applied, they will appear within a "rules {
... }" block in the command output. This is more effective than Option A, which only lists the contents of the iRule itself but does not show if or where it is applied. Option C is a common misconception; while some versions of the GUI have reorganized menus, the standard location for managing the association of profiles, policies, and iRules to a Virtual Server remains the "Resources" section. By identifying the applied iRule, an administrator can then review the script logic-often containing commands like pool or node-to see if it is overriding the default pool selection based on specific HTTP headers, URI paths, or client IP addresses.
NEW QUESTION # 17
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.
