質問 # 58
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?
正解:A
解説:
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.

In the BIG-IP Configuration Utility, a user requests a single screen view to determine the status of all Virtual Servers and associated pool members, as well as any iRules in use. Where should the BIG-IP Administrator instruct the user to find this view?
正解:B
解説:
The Local Traffic > Network Map provides a single consolidated view within the BIG-IP Configuration Utility that displays the full relationship hierarchy of all application delivery objects simultaneously. This includes Virtual Servers, their associated Pools, individual Pool Members, applied iRules, profiles, and the health status of each object - all rendered in a single topological screen.
This view is specifically designed for administrators and users who need rapid situational awareness across the data plane without navigating multiple menu screens. Each object is colour-coded to reflect its current availability state (green = available, red = unavailable, yellow = degraded).
The alternative options do not satisfy all requirements:
* Local Traffic > Monitors only displays health monitor configurations, not virtual server or pool member relationships.
* Statistics provides performance counters and throughput data, not object relationship mapping.
* Local Traffic > Virtual Servers lists virtual server configurations individually but does not provide a unified topology view inclusive of pool members and iRules in a single screen.
The Network Map is the authoritative single-pane-of-glass tool for application object visibility on BIG-IP.

質問 # 60
A web server administrator informs the BIG-IP Administrator that web servers currently load-balanced require encrypted traffic. Starting next month, the web server administrator will offload SSL. Starting next month, the BIG-IP device will terminate SSL to reduce web server load. The BIG-IP device is already using Client SSL, Client port, and iRules on HTTP traffic. What actions should the BIG-IP Administrator take to achieve the desired configuration? (Choose one answer)
正解:B
解説:
To solve this requirement, we must distinguish between the two "legs" of an SSL connection in a BIG-IP environment: Client-side and Server-side.
* Current State (SSL Bridging): The administrator states the servers currently require encrypted traffic.
This means the BIG-IP is likely performing "SSL Bridging." In this setup, a Client SSL profile terminates encryption from the user, and a Server SSL profile re-encrypts the traffic before sending it to the back-end servers.
* Target State (SSL Offloading): The requirement is to "offload SSL" to reduce web server load. This means the BIG-IP will continue to handle the encryption for the users (keeping the Client SSL profile) but will communicate with the back-end servers using unencrypted HTTP.
Why Option A is correct:
* Remove the Server SSL profile: By removing this profile, the BIG-IP stops attempting to initiate an SSL
/TLS handshake with the pool members.
* Configure Pool Members to use HTTP: The service port for the pool members must be changed (typically from port 443 to port 80) so that the BIG-IP sends standard HTTP traffic to the servers.
Why other options are incorrect:
* B & D: These suggest removing the Client SSL profile. If you remove this, the users can no longer connect via HTTPS, which violates the requirement for encrypted communication between the users and the BIG-IP.
* C: Changing the Virtual Server to accept HTTP traffic would mean the user-to-BIG-IP connection is no longer encrypted, which is the opposite of SSL termination/offloading.
質問 # 61
A Standard Virtual Server reports poor performance for Internet users.
What TCP profile configuration should be applied?
正解:B
解説:
WAN-optimized TCP profiles improve performance for high-latency Internet clients, while LAN profiles are optimal for backend servers.
質問 # 62
A BIG-IP Administrator needs to apply persistence to a virtual server that is configured as a Performance (Layer 4) virtual server that allows access to a secure (TLS) e-commerce website.
What type of persistence profile can be used? (Choose one answer)
正解:C
解説:
A Performance (Layer 4) virtual server does not inspect or process application-layer data such as HTTP headers or cookies. Therefore, only Layer 4-compatible persistence methods can be used.
According to the BIG-IP Administration: Data Plane Configuration documentation:
Source Address Affinity persistence operates at Layer 4 and uses the client IP address to maintain session persistence.
It is fully compatible with Performance (Layer 4) virtual servers.
It works regardless of encryption, making it suitable for TLS-secured applications.
Why the other options are incorrect:
B . Cookie persistence
Requires an HTTP profile and Layer 7 inspection, which is not supported on Performance virtual servers.
C . Microsoft RDP persistence
Is protocol-specific and not applicable to web-based TLS traffic.
D . Host persistence
Requires HTTP host header inspection, which is not available at Layer 4.
Correct Resolution:
Source Address Affinity persistence is the appropriate choice for maintaining persistence on a Performance (Layer 4) virtual server handling TLS traffic.
