300-910 Question #77: Real Exam Question with Answer & Explanation

Question

Based on the provided Network PIE - Contributors chart, which action should be taken given the spike in RTOS around 9:10?

Options

• ARestart the service to re-establish the connection with the nodes and clear the path.
• BDecrease the load on the MySQL databases to release the hardware resources available for node distribution
• CCheck with the planning team to understand if the number of nodes in the Ecom tier can be increased to handle traffic
• DContact the network team to investigate the network path that caused this intermittent issue around 9:10.

Explanation

A spike in RTOS, indicating real-time operation or response time issues, often suggests a transient problem with a service's internal state or connections.

Common mistakes.

• B. Decreasing load on MySQL databases is a potential solution for database-related bottlenecks, but without more information directly linking the RTOS spike to database load, it's not the primary or most immediate action.
• C. Increasing the number of nodes in the Ecom tier might address scalability issues, but a sudden 'spike' often points to an immediate problem with an existing service instance rather than a lack of overall capacity.
• D. Contacting the network team is appropriate for network-level issues (like general latency or packet loss), but if the RTOS spike is an application-specific metric, the problem might originate at the application or service layer rather than solely in the underlying network path.
