Cisco 200-901 Online Questions & Answers

• Question 481:

  A network engineer makes several API calls to Cisco Prime to retrieve a list of all devices. Each time a response is received, only a subset of the devices is returned. The engineer notices that HTTP code 429 is returned instead of 200 for some API calls. Why did the response exclude some of the devices?

  A. The API applied an offset that was indicated in the request.
  B. The API failed to identify how many items to retrieve.
  C. The API timed out the request.
  D. The API rate limited the request.
  D. The API rate limited the request.

  ---

  HTTP status code 429 indicates that too many requests have been sent in a given amount of time, which is a sign of rate limiting. Rate limiting is used by APIs to control the amount of incoming requests to prevent abuse or overloading the server. In this case, the Cisco Prime API is limiting the number of requests the network engineer can make in a certain time period, resulting in only a subset of devices being returned and some requests being rejected with a 429 status code.

• Question 487:

  What is the function of an Ethernet switch in a networking environment?

  A. to switch a frame from one port to another port based on IP address
  B. to switch a frame from one port to another port based on MAC address
  C. to provide IP addressing to connected hosts
  D. to block unwanted traffic
  B. to switch a frame from one port to another port based on MAC address

  ---

  An Ethernet switch operates at the Data Link layer (Layer 2) of the OSI model. Its primary function is to forward frames between devices based on their MAC (Media Access Control) addresses. When a frame arrives at the switch, the switch reads the destination MAC address and forwards the frame to the appropriate port that connects to the device with that MAC address. MAC Address Table: Switches maintain a MAC address table that maps each MAC address to a specific port. This table is built dynamically as the switch learns the MAC addresses of devices connected to its ports. Frame Switching: By using the MAC address table, the switch can efficiently switch frames only to the destination port, which reduces unnecessary traffic on other ports and improves network performance.
