NEW QUESTION # 87
In a pool there are 2 pool members out of the 5 members that are older servers. The number of connections these can handle is less than the other 3 pool members. Which load balancing method would allow more traffic to be directed to the newer servers?
Answer: B
Explanation:
When dealing with heterogeneous server hardware where some servers are more powerful than others, a dynamic load balancing method that accounts for both current load and server capacity is required. The Weighted Least Connections (member) method is the most appropriate choice. This method works by tracking the number of active connections to each pool member and then "weighting" that number based on a user-defined Ratio value assigned to the member. For example, the administrator can assign a higher Ratio to the three newer, more powerful servers and a lower Ratio to the two older servers. The BIG-IP then uses a formula to calculate which server should receive the next connection, ensuring that the newer servers handle a proportionately larger share of the total concurrent connections.
Standard Round Robin (Option C) would be ineffective because it distributes connections strictly sequentially (1, 2, 3, 4, 5) without regard for the servers' capacity or current load, which would eventually overwhelm the older servers. Least Connections (member) (Option D) is better than Round Robin because it picks the server with the fewest active connections, but it still assumes all servers are equal; it would try to keep the connection counts identical across all 5 servers, which would still stress the older hardware more than the new. Global Availability (Option B) is a GSLB (DNS-based) method used for multi-site redundancy, not for local pool member load balancing. By using Weighted Least Connections, the administrator achieves a balance where the more capable servers take the brunt of the work while the older servers are utilized only to their specific safe capacity.
NEW QUESTION # 88
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: C,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 # 89
A virtual server is configured to offload SSL from a pool of backend servers. When users connect to the virtual server, they successfully establish an SSL connection but no content is displayed. A packet trace performed on the server shows that the server receives and responds to the request. What should a BIG-IP Administrator do to resolve the problem?
Answer: B
Explanation:
This scenario describes a classic routing issue often encountered during SSL offload deployments. The fact that an SSL connection is established indicates the Client SSL profile is working correctly. The packet trace showing the server "receives and responds" to the request is the most critical diagnostic clue.
When a BIG-IP receives traffic, it typically passes the client's original source IP address to the backend server. If the backend server's default gateway is not the BIG-IP (a common "one-arm" network topology), the server will attempt to send its response directly back to the client's IP via its own default router. The client's browser will reject this response because it expects traffic to come from the Virtual Server's IP, not the backend server's IP.
To resolve this, the administrator must enable SNAT (Source Address Translation), typically using SNAT Automap. When SNAT is enabled, the BIG-IP replaces the client's original source IP with one of its own Self IPs before forwarding the request to the server. Because the source of the packet is now the BIG-IP, the backend server is forced to send its response back to the BIG-IP. The BIG-IP then receives the response, translates it back, and delivers the content to the user. Option A is unnecessary if the servers are expecting plain-text traffic after the BIG-IP performs offload. Option D would only worsen the existing routing discrepancy.
NEW QUESTION # 90
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)
Answer: A
Explanation:
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.
NEW QUESTION # 91
An LTM device has a virtual server mapped to www.f5.com with a pool assigned. The objects are defined as follows: Virtual server: Destination 192.168.245.100:443 netmask 255.255.255.0. Persistence: Source address persistence netmask 255.0.0.0. SNAT: Automap. Profiles: HTTP/TCP. How should the BIG-IP Administrator modify the persistence profile so that each unique IP address creates a persistence record?
Answer: B
Explanation:
Source Address Affinity (Persistence) works by tracking the source IP address of incoming packets to ensure a client stays connected to the same backend server. The " netmask " setting within the persistence profile determines the " granularity " of this tracking. A netmask tells the BIG-IP how many bits of the source IP address to ignore when creating the persistence record. For example, the current setting of 255.0.0.0 (a /8 mask) means the BIG-IP only looks at the first octet of the IP; this results in all users from the same large Class A network (e.g., everyone from 10.0.0.0 to 10.255.255.255) being persisted to the exact same server, which can lead to severe load imbalance.
To ensure that each unique IP address creates its own individual persistence record, the administrator must set the netmask to 255.255.255.255 (for IPv4). This is a " host mask " or /32, which instructs the BIG-IP to evaluate all 32 bits of the client ' s source IP address. With this setting, 10.1.1.1 and 10.1.1.2 will be treated as distinct entities and can be load balanced to different servers, each maintaining their own " stickiness " .
While Option A (255.255.255.0) would group users by their local subnet, only the full 255.255.255.255 mask satisfies the requirement for true unique-IP persistence. This configuration is standard for internet-facing applications where users arrive from diverse locations and the administrator wants to maintain the most granular and balanced distribution of traffic possible.
