1 pointsHow does a networked server manage requests from multiple clients for different services?Correct
Incorrect
Each service provided by a server, such as email or file transfers, uses a specific port number. The source port number of a service request identifies the client that is requesting services.

Question 35 of 40
35. Question
1 pointsWhat will a host on an Ethernet network do if it receives a frame with a destination MAC address that does not match its own MAC address?Correct
Incorrect
In an Ethernet network, each NIC in the network checks every arriving frame to see if the destination MAC address in the frame matches its own MAC address. If there is no match, the device discards the frame. If there is a match, the NIC passes the frame up to the next OSI layer.Hint

Question 38 of 40
38. Question
1 pointsWhat statement describes the function of the Address Resolution Protocol?Correct
Incorrect
When a PC wants to send data on the network, it always knows the IP address of the destination. However, it also needs to discover the MAC address of the destination. ARP is the protocol that is used to discover the MAC address of a host that belongs to the same network.Hint

39. Question
1 pointsWhat is the purpose of having a converged network?Correct
Incorrect
With the development of technology, companies can now consolidate disparate networks onto one platform called a converged network. In a converged network, voice, video, and data travel over the same network, thus eliminating the need to create and maintain separate networks. This also reduces the costs associated with providing and maintaining the communication network infrastructure.Hint
