Question 1

Multicasting delivers the content to ___________&#10;A)a single client&#10;B)all clients, regardless whether they want the content or not&#10;C)a group of receivers who indicate they wish to receive the content&#10;D)none of the mentioned

Accepted Answer

Multicasting is a method used to deliver content to a group of receivers who have indicated their desire to receive the content, making it efficient for distributing information to multiple interested parties without burdening the network or the source.

Question 2

HTTP is __________&#10;A)a stateful protocol&#10;B)a stateless protocol&#10;C)a protocol that maintains the status of its connection with the client&#10;D)a stateless protocol that does not maintain the status of its connection with the client

Accepted Answer

a stateless protocol that does not maintain the status of its connection with the client&#10;

Question 3

The problem with unicast delivery is that the ___________&#10;A)memory allocation is difficult&#10;B)server must establish a separate unicast session for each client&#10;C)the routers must support unicasting&#10;D)the clients must be close to the server

Accepted Answer

Unicast delivery requires the server to establish a separate connection or session for each client requesting the data, leading to scalability issues as the number of clients increases.

Question 4

The difficulty with multicasting from a practical point of view is ___________&#10;A)memory allocation is difficult&#10;B)server must establish a separate unicast session for each client&#10;C)the routers must support multicasting&#10;D)none of the mentioned

Accepted Answer

The primary practical difficulty with multicasting is that it requires routers to support multicasting. This is because multicasting involves sending a single copy of data to multiple recipients, which requires routers to replicate the data at appropriate points in the network to reach all intended recipients. If routers do not support multicasting, this efficient distribution mechanism cannot be utilized.

Question 5

To let a client have random access to a media stream with ___________&#10;A)the protocol used must not be stateless&#10;B)the server must support download&#10;C)the stream should give access rights to the client&#10;D)all of the mentioned

Accepted Answer

The answer of To let a client have random access...

Question 6

An RPC (remote procedure call) is initiated by the:&#10;A)server&#10;B)client&#10;C)both (a) and (b)&#10;D)neither (a) nor (b)&#10;

Accepted Answer

An RPC is initiated by the client, who sends a request to the server to execute a procedure as if it were a local call, waiting for the server to process the request and respond.

Question 7

RPC works between two processes. These processes may be:&#10;A)on the same computer&#10;B)on different computers connected with a network&#10;C)both (a) and (b)&#10;D)neither (a) nor (b)&#10;

Accepted Answer

RPC (Remote Procedure Call) allows a program to cause a procedure to execute in another address space (on the same or another computer) on a shared network, which means it works for both scenarios: when processes are on the same computer and when they are on different computers connected by a network.

Question 8

_____is a framework for distributed objects on the Microsoft platform.&#10;A)CORBA&#10;B)DCOM&#10;C)DDObjects&#10;D)none

Accepted Answer

DCOM (Distributed Component Object Model) is a Microsoft technology for software components distributed across several networked computers to communicate with each other. CORBA is a cross-platform equivalent, and DDObjects is not as widely recognized or directly associated with Microsoft for distributed objects.

Question 9

___ is a framework for distributed components using a messaging paradigm.&#10;A)CORBA&#10;B)DCOM&#10;C)DDObjects&#10;D)Jt

Accepted Answer

The answer of ___ is a framework for distributed components...
