질문 # 47
Refer to the exhibit.


A BIG-IP Administrator configures a Virtual Server to handle HTTPS traffic. Users report that the application is NOT working. Which additional configuration is required to resolve this issue?

정답:B

설명:
According to the provided exhibit, the "SSL Profile (Client)" section in the Virtual Server configuration is empty. For a BIG-IP system to process HTTPS traffic, it must act as an SSL/TLS endpoint. This process, known as SSL Termination or SSL Offload, requires the assignment of a Client SSL Profile to the Virtual Server. Without this profile, the BIG-IP does not have the necessary certificate and private key information to perform the SSL handshake with the client's browser. Consequently, when a user attempts to connect via HTTPS, the TCP connection may establish, but the SSL handshake will fail because the BIG-IP will not know how to decrypt the incoming encrypted packets.
A Client SSL profile defines the ciphers, certificates, and keys that the BIG-IP uses to communicate securely with the client. In a standard HTTPS deployment, the BIG-IP decrypts the traffic and can then send it to the backend pool members either as plain text (header insertion/manipulation) or re-encrypt it using a Server SSL profile. While a Server SSL profile (Option C) is needed if the backend servers themselves require HTTPS, the initial failure for a user reaching a Virtual Server is almost always the lack of a Client SSL profile to terminate the user's connection. Changing the Service Port to HTTP (Option D) would be incorrect because the goal is to handle HTTPS traffic (typically port 443). Assigning the "clientssl" or a custom client-side profile from the "Available" list to the "Selected" list in the GUI is the mandatory step to make the Virtual Server operational for secure web traffic.


질문 # 48
Which persistence profile would be the most appropriate to ensure an HTTP web request connects to the same pool member? (Choose one answer)

정답:A

설명:
For HTTP-based applications, cookie persistence is the most appropriate and commonly recommended persistence method.
According to the BIG-IP Administration: Data Plane Configuration documentation:
* Cookie persistence inserts or uses an HTTP cookie to maintain session affinity.
* It operates at Layer 7 (HTTP) and is application-aware.
* It allows persistence to be maintained even when multiple clients are behind a NAT device.
Why the other options are incorrect:
* A. Destination addressDestination address persistence is generally used for inbound traffic patterns such as firewall or proxy scenarios.
* B. Hash persistenceHash persistence is less granular and not HTTP-specific.
* C. SSL persistenceSSL persistence is typically used when SSL session IDs are reused and is less reliable than cookies for HTTP applications.
Correct Resolution:
Using cookie persistence ensures that HTTP web requests are consistently directed to the same pool member.


질문 # 49
A BIG-IP Administrator is configuring an SSH Pool with five members. Which Health Monitor should be applied to ensure that available pool members are monitored accordingly?

정답:D

설명:
SSH (Secure Shell) operates over TCP port 22 , making the TCP health monitor the appropriate and correct choice for monitoring pool members in an SSH pool. The TCP monitor establishes a basic Layer 4 connection to each pool member on the designated port, verifying that the server is reachable and actively accepting TCP connections. A successful three-way handshake confirms the pool member is available; a failure marks it down and removes it from load balancing rotation.
The remaining monitor types are inappropriate for this use case:
* UDP monitor operates at Layer 4 but uses the connectionless UDP protocol, which is incompatible with SSH since SSH exclusively uses TCP as its transport.
* HTTP monitor sends a Layer 7 GET request expecting an HTTP response - irrelevant for an SSH service that does not speak the HTTP protocol.
* HTTPS monitor functions identically to HTTP but over TLS - again, completely misaligned with SSH traffic and port behaviour.
For application-specific SSH validation beyond basic TCP connectivity, an external monitor or custom monitor could be used; however, TCP remains the standard and correct built-in monitor for SSH pool verification within the BIG-IP platform.

질문 # 50
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?

정답:B

설명:
The virtual server is intended to process SSH traffic on TCP port 22 , but the exhibit shows that the standard
http HTTP profile is assigned. This is the configuration error. An HTTP profile enables BIG-IP Layer 7 HTTP processing and is appropriate only when the virtual server is expected to process HTTP protocol traffic.
F5 documentation defines its purpose directly: "An HTTP profile defines the way that you want the BIG- IP system to manage HTTP traffic." SSH is not HTTP. It is an independent application protocol transported over TCP , conventionally using port
22 . Therefore, an ordinary SSH load-balancing virtual server should retain the TCP protocol/profile while having HTTP Profile set to None . F5 ' s SSH virtual-server configuration guidance specifically uses service port 22 for SSH and does not require an HTTP profile.
Options B, C, and D do not address the fault. The destination address 10.1.1.2 correctly identifies the virtual server, while source 0.0.0.0/0 appropriately permits clients from any source. Changing the protocol to UDP would be incorrect because SSH requires TCP.
Reference Topics: Virtual Server configuration; HTTP profiles; TCP profiles; application-protocol profile assignment; SSH traffic handling.


질문 # 51
Which two load balancing methods consider all the connections the BIG-IP has between it and each backend application server (Pool Member) when making a load balancing decision for a new connection?

정답:A,D

설명:
The two load balancing methods that consider all connections between the BIG-IP and each backend node
- not just connections to a specific pool member - are Least Connections (node) and Weighted Least Connections (node) .
The critical distinction here lies in the node-level scope of evaluation. A node represents the backend server ' s IP address, regardless of how many services or ports it may be serving. Therefore:
* Least Connections (node) directs new connections to the node with the fewest total active connections across all services on that server, providing a holistic connection-count perspective.
* Weighted Least Connections (node) operates identically but factors in an administrator-defined ratio weight, allowing servers with greater capacity to proportionally absorb more connections while still evaluating total node-level connection counts.
By contrast:
* Ratio (member) distributes traffic based on a static weight ratio and does not dynamically evaluate current connection counts.
* Round Robin distributes traffic sequentially in rotation, completely ignoring current connection states on any node or member.
The node-based methods are particularly valuable in environments where a single backend server hosts multiple pool members across different ports, ensuring the server ' s overall load - not just per-service load
- governs balancing decisions.
