1

You are looking at a network traffic log and see TCP connections that use the SYN, SYN/ACK, and ACK flags set. What type of communication is this?

1

Which of the following layers of the OSI model use data as their Protocol Data Units? (choose two)

1

Which of the following layers is concerned with changing the format of data into something that the layer above it and the layer below it can understand.?

1

You are teaching a class on the OSI model, and one of the students has a question about how the TCP/IP protocol stack maps to the OSI model. Which of the following best describes the mapping of the TCP/IP layers to the OSI model layers?

1

Which of the following transport layer protocols is not concerned with connection establishment, error correction, or flow control?

1

Which layer in the TCP/IP protocol stack is concerned with routing and logical addressing?

1

As a junior-level network technician, you are asked to build a simple network, connecting just a few hosts together. None of the them are dedicated servers, and they are all equal in the network in terms of function. They also must each have their own security requirements, such as usernames and passwords, that aren't shared between them. What is the best network to design that meets these requirements?

1

Your server is pushing app notifications to your iOS devices, but you receive some messages back that indicate that the notifications failed for various reasons. Which protocol would have sent those failure notifications back to your server?

1

You are reviewing your network logs and see a high amount of traffic using TCP port 3389. What kind of connections could account for this traffic?

1

Which two ports are valid for Simple Mail Transfer Protocol (SMTP) and Alternate SMTP? (choose two)

1

You are trying to minimize the number of protocols used on the network that don't communicate securely. Which one of the following protocols should you review for switching to a secure alternative?

1

Which of the following mobile devices would you expect to use TCP port 2195 for its updates?

1

Which of the following protocols offer some level of encryption and authentication for network traffic that uses it?

1

All of the following are protocols that are routinely used over SSL to provide enhanced security EXCEPT:

1

Which of the following protocols provides for automatic assignment of IP addressing information to network hosts?

1

DNS uses which of the following port and protocol combinations (choose two)

1

You are looking at a network log file that shows communications between a client and a web server. You see that two ports were in use during the communications session, port 50123 and port 80. Which port would be the source and which port the destination when the client is sending a request to the web server? (choose two)

1

You have configured an FTP server to listen on a non-standard port, TCP port 3135. When you try to test the connection using FTP client software from another host, the connection fails. Assuming there's no other problem with the connection to the server, what should you do to complete the configuration so that clients can connect to the new FTP service on the correct port?
