Question

QUESTION 1 Which of the following is false about functions of a layer in the Network Model? A layer in the network model may send a protocol data unit to the lower layers. A layer in the network model has to be able to receive protocol data unit form upper layers A layer in the network model should be able to receive protocol data unit from both upper and lower layers. A layer in the network model should only be able to receive, but not send, protocol data units to the upper layer. 2 points Saved QUESTION 2 Which of the following is false about headers in a network model? A header appended at a layer is not re-written by the lower layers in the same host A header appended at a layer will contain information specific to a protocol The header appended at a layer in the sending host, can be removed by lower layers at the receiving host A header appended at a layer in the sending host, cannot be removed by upper layers in the receiving host 2 points Saved QUESTION 3 Which of the following is false about protocol data units? A protocol data unit may contain no data in its header, but will always contain data in its body A protocol data unit is the result of encapsulation at a layer in the network model. The header appended to a protocol data unit at a particular layer in the sending host can only be removed by the same layer in the receiving host. It is possible to have data only in the header part of a protocol data unit and with no contents in its body. 2 points Saved QUESTION 4 Which of the following is false about HTTP protocol. Body of an HTTP protocol data unit can contain the HTML code of a web page HTTP data transfer can either be a request for a web page, or a response from a web server. GET messages are placed within the body of an HTTP protocol data unit. In an HTTP request message, the URL is written in the header of the HTTP protocol data unit. 2 points Saved QUESTION 5 Which of the following is false about SMTP ? SMTP is used to send email from a user agent to her mail box in a mail server. SMTP is used to retrieve email by an user agent from her mail box in a mail server SMTP is used to send email from the sender's mail server to the recipient's mail server. SMTP is not used by the recipient to retrieve her email from her mail server 2 points Saved QUESTION 6 Which of the following is false about Client-server computing ? In a client-server architecture a server process is created to serve each client process A client server architecture has a logical star structure with the server in the center of the star In a client server application, a client can derive data generated by another client, only through the server (and not directly from the client). It is possible to have multiple server processes in a server host machine, but it is not possible to have multiple client processes within the same client host machine. 2 points Saved QUESTION 7 Which of the following is false about peer to peer computing architecture? In a peer to peer application, the same host machine can carry a client process and server process, at the same time. A peer to peer application is a logical mesh at the application layer A peer to peer application can greatly suffer by the failure of any one machine (host) in the system A peer to peer application such as the Bit Torrent uses a tracker to locate hosts with specific files. 2 points Saved QUESTION 8 Which of the following is false about cloud based services? In the Software as a Service cloud architecture, the organization uses a very thin client and outsources the entire application- software and infrastructure, to the cloud service provider. In the Infrastructure as a Service cloud architecture, the organization outsources all the hardware, but manages the software and data on it own. In Platform as a Service cloud architecture, the application and data is managed by the organization, but the remaining software and hardware are outsourced to a cloud service provider In an On Premises computing architecture, application and data can be outsourced to a cloud service provider, but all other software and hardware are maintained and hosted in house. 2 points Saved QUESTION 9 Which of the following are not part of an application architecture? Presentation logic Data Link Data Storage Data Access logic 2 points Saved QUESTION 10 Which of the following are false about Client Server and Peer to Peer architecture? At the application layer, client server is a logical star, but peer to peer is logical mesh HTTP and FTP are client server protocols. SMTP is a peer to peer application (just) between the mail servers Economies of Scale and centralized control are more prevalent in a peer peer application than in a client server application.
