A financial services company is experiencing intermittent latency with their online trading platform during peak hours. The network team uses SteelCentral NetProfiler to monitor traffic. They've noticed that while overall bandwidth utilization is acceptable, certain TCP connections show high 'Server Delay'. To investigate further, they need to isolate traffic specifically for the trading application, which uses a proprietary protocol on TCP port 3307. Which NetProfiler feature is most effective for creating a dedicated, long-term view of this specific application's performance metrics?

A network engineer is using SteelCentral Packet Analyzer to diagnose a slow file transfer issue between a client and a server. The packet trace shows multiple TCP segments with the 'TCP Window Full' message from the receiver (server). Concurrently, the sender (client) exhibits several 'TCP Zero Window' probes. What is the most likely root cause of this performance problem based on the packet evidence?

A company has deployed a SteelCentral NetShark appliance to perform continuous packet capture in their data center. To conserve storage space, the network team wants to capture only the traffic related to their critical database servers, which reside in the 10.50.10.0/24 subnet. They also want to exclude all SSH (TCP port 22) management traffic from the capture. Which of the following NetShark capture job configurations would achieve this?

A large e-commerce company, 'ShopFast,' is preparing for its annual holiday sales event. Their primary customer-facing application is a multi-tier web service hosted in a hybrid cloud environment. In previous years, they experienced slowdowns where customers reported pages taking over 10 seconds to load, but the infrastructure team could not pinpoint the cause, blaming either the network, database, or web servers. This year, they have deployed SteelCentral AppResponse to gain deeper insight. The key business requirement is to proactively identify which specific web pages and underlying database queries are contributing to poor user experience. The IT director wants a single metric that represents the end-user's perception of performance for every transaction. They also need the ability to drill down from a slow user session directly to the associated network and server metrics to facilitate rapid root cause analysis between the network, server, and application teams. The current setup includes AppResponse monitoring traffic from a SPAN port in front of the web server farm. The network team has confirmed that all client-to-server and server-to-database traffic is visible to the appliance. The goal is to isolate the 'blame' for slowdowns to either network latency, server processing time, or specific application components. Which AppResponse capability is most critical for ShopFast to configure and monitor to meet the IT director's requirement for a single, user-centric performance metric and enable blame-domain isolation?

True or False: The primary function of the SteelCentral Flow Gateway is to perform deep packet inspection (DPI) and generate application-level performance metrics.

A network administrator is configuring Host Groups in SteelCentral NetProfiler to better organize and report on traffic from different company departments. What are two key benefits of using Host Groups? (Select TWO)

An engineer is analyzing a performance issue in a three-tier application using data from a NetShark appliance. The analysis shows significant delays. The engineer suspects the issue is between the Application Server and the Database Server. The following diagram represents the TCP round-trip time (RTT) measurements from the NetShark's perspective. Given the data presented, where is the most likely source of the application delay? ```mermaid sequenceDiagram participant Client participant AppServer as Application Server participant DBServer as Database Server Client->>AppServer: HTTP Request Note right of Client: Network RTT (Client-App): 20ms AppServer->>DBServer: SQL Query Note right of AppServer: Server Processing: 50ms Note right of AppServer: Network RTT (App-DB): 150ms DBServer-->>AppServer: SQL Result Note left of DBServer: DB Processing: 30ms AppServer-->>Client: HTTP Response ```

A network operations team uses SteelCentral Portal to display a consolidated view of network and application performance. The team lead wants to create a custom dashboard that shows the top 10 applications by bandwidth from NetProfiler alongside the top 5 web applications by user experience time from AppResponse. Which Portal feature should be used to accomplish this?

When using SteelCentral Transaction Analyzer to troubleshoot a multi-tier application, what is the primary purpose of creating a 'Transaction' model?

A company is deploying SteelCentral NetProfiler Enterprise, which consists of a separate database, application, and web server. What is the primary reason for this distributed architecture compared to the all-in-one NetProfiler appliance?
