Question 3

​____ specifies the middleware objects use to interact across networks.
A) ​COM+
B) ​LDAP
C) ​CIFS
D) ​CORBA

Accepted Answer

CORBA (Common Object Request Broker Architecture) is a middleware that provides a standard for objects to communicate with each other across networks. It specifies the interface description language (IDL) and object request broker (ORB) needed for distributed object communication.

Question 4

​A ____ is a region of shared memory through which multiple processes executing on the same machine can exchange data.
A) ​map
B) ​pipe
C) ​socket
D) ​process

Accepted Answer

A pipe is a method of inter-process communication that allows processes running on the same machine to exchange data through a shared region of memory.

Question 5

____ is an open standard, developed by the World Wide Web Consortium, for distributed object interaction that attempts to address the shortcomings of both CORBA and COM+.
A) XML-RPC
B) Simple Object Access Protocol
C) ​OLE
D) ​HTTP

Accepted Answer

The only option that fits the description provided is Simple Object Access Protocol (SOAP). XML-RPC is also an open standard for distributed object interaction, but it does not attempt to address the shortcomings of CORBA and COM+. OLE is a Microsoft technology for compound documents, not distributed object interaction. HTTP is a protocol, not an open standard for distributed object interaction.

Question 6

​A(n) ____ describes rights granted or denied to users, groups, and computers for accessing resources in Active Directory.
A) ​access control list
B) ​access control entry
C) ​token
D) ​access control token

Accepted Answer

An access control list (ACL) describes the permissions that are granted or denied to users, groups, and computers for accessing resources in Active Directory. It is a list of Access Control Entries (ACEs) that determines who is authorized to access a particular resource and what actions they are allowed to perform on that resource. Tokens and Access Control Tokens are related to authentication and authorization, but they do not directly control access to resources in Active Directory.

Question 7

Under ____, e-mail messages are held on the server temporarily, downloaded to the client when a connection is established, and deleted from the server as soon as the download is finished.
A) IMAP
B) ​POP3
C) ​SMTP
D) ​NNTP

Accepted Answer

POP3 (Post Office Protocol version 3) is the protocol that allows retrieving emails from a mail server. Under POP3, the messages are held on the server until they are downloaded by the client. Once downloaded, they are deleted from the server, unless the client is set up to leave a copy on the server. IMAP, on the other hand, allows messages to be stored on the server and accessed from multiple devices, without deleting them unless instructed to do so. SMTP is a protocol for sending emails, and NNTP is a protocol for accessing newsgroups.

Question 8

A(n) ____ is a standardized, interchangeable software module that is executable, has a unique identifier and has a well-known interface.
A) ​object
B) ​bean
C) ​component
D) ​resource

Accepted Answer

A component is a standardized, interchangeable software module that is executable, has a unique identifier and has a well-known interface. Objects refer to instances of classes, beans are a type of component used specifically in Java programming, and resources can refer to various types of assets or data used by a software system.

Question 9

​Active Directory clients rely on a ____ to locate Active Directory servers.
A) ​WINS server
B) ​DHCP server
C) ​BOOTP server
D) ​DNS server

Accepted Answer

Active Directory clients use DNS to locate Active Directory servers. DNS provides a hierarchical naming structure that allows clients to locate domain controllers by their fully qualified domain names. This enables clients to locate the closest domain controller and also provides fault tolerance in the event that a domain controller fails. WINS, DHCP, and BOOTP are not used for locating Active Directory servers.

Question 10

SMTP was extended by the ____ protocol to allow including nontext files in e-mail messages.
A) ​Multimedia Internet Mail Extensions
B) ​Multiple Internet Mail Extensions
C) ​Multipurpose Internet Mail Extensions
D) ​Multiuse Internet Mail Extensions

Accepted Answer

SMTP was extended by the Multipurpose Internet Mail Extensions (MIME) protocol to allow including nontext files in email messages.

Question 11

In CORBA, ____ is a component message-passing protocol.
A) Internet Inter-ORB Protocol
B) Local Inter-ORB Protocol
C) SOAP
D) ​XML-RPC

Accepted Answer

Internet Inter-ORB Protocol (IIOP) is a protocol used for communication between CORBA (Common Object Request Broker Architecture) objects located in different applications, possibly on different computers. It enables CORBA objects to communicate over the internet, making it a key component for message-passing in CORBA systems.

Question 12

​____ are commonly used for communication between OS components, for queuing requests to an OS service, and for exchanging messages between components in a large program.
A) ​Sockets
B) ​Packets
C) ​Pipes
D) ​Procedures

Accepted Answer

Pipes are commonly used for communication between OS components and for exchanging messages between components in a large program.

Answer: D 
 Procedures can also be used for communication between OS components and exchanging messages between components in a large program. However, the question specifically mentions queuing requests to an OS service, which is not typically accomplished through procedure calls. Therefore, while procedures can be used for communication and message passing, pipes are the more relevant answer for this question.

Sockets are typically used for communication between separate processes or even separate devices on a network, so they are not as relevant for communication within an OS. Packets are a lower-level concept that refers to the format in which data is transmitted across a network, so they are not directly related to communication between OS components.

Question 13

​Microsoft ____ is the directory service and security system built into Windows Server.
A) ​Directory Services
B) ​Open Directory
C) ​Active Directory
D) ​Network Directory

Accepted Answer

Active Directory is the directory service and security system built into Windows Server. It is used to manage permissions and access to network resources, as well as to authenticate and authorize users and computers.

Question 14

​Web resources are identified by a unique ____.
A) ​Uniform Resource Leverage
B) ​Uniform Resource Locator
C) ​Uniform Resource Link
D) ​Uniform Resource Path

Accepted Answer

Web resources are identified by a unique Uniform Resource Locator (URL), which is a web address used to locate a particular website or web page. The other options listed in the question are not correct.

Question 15

In CORBA, ____ is a service that maintains a component directory and routes messages between components.
A) Object Reference Broker
B) Object Request Broker
C) Object Resource Broker
D) ​Object Repair Broker

Accepted Answer

The Object Request Broker (ORB) is responsible for maintaining a component directory and routing messages between components in CORBA.

Question 16

____ enable developers to create user interfaces that run on a server but interact with a client Web browser or component.
A) ​JavaServer Beans
B) ​Enterprise Java Beans
C) ​JavaServer Faces
D) ​JavaFX

Accepted Answer

JavaServer Faces enables developers to create user interfaces that run on a server but interact with a client Web browser or component. JavaServer Beans and Enterprise Java Beans are used for building backend business logic and data access components in a Java EE application. JavaFX is a client-side technology for creating rich internet applications and is not directly related to server-side user interfaces.

Question 17

​____ is an improved version of Telnet that encrypts data flowing between client and server to address a major security issue in Telnet.
A) ​Secure Shell
B) ​FTP
C) ​Kerberos
D) ​DCE

Accepted Answer

Secure Shell (SSH) is an improved version of Telnet that supports secure encrypted connections. SSH encrypts all data exchanged between client and server, including login credentials and other sensitive information. This addresses a major security issue with Telnet, which sends data in plain text and does not provide any protection against interception or eavesdropping. FTP, Kerberos, and DCE are not related to the issue of securing Telnet connections.

Question 18

​In an LDAP directory, a(n) ____ defines the attributes common to all member objects.
A) ​distinguished name
B) ​common name
C) ​objectType
D) ​objectclass

Accepted Answer

The objectclass defines the attributes common to all member objects in an LDAP directory. The objectclass also determines which attributes must be present, allowed, and required for particular types of objects in the directory. Distinguished name (A) refers to the unique identifier for an object in the directory while common name (B) refers to the name used to identify an object within its container or organizational unit. ObjectType (C) is not a standard LDAP attribute.

Question 19

​With the ____ protocol, a process on one machine can call a process on another machine.
A) ​Remote Activation Call
B) ​Remote Procedure Call
C) ​Remote Execution Call
D) ​Remote Calling Convention

Accepted Answer

Remote Procedure Call (RPC) allows a process running on one machine to call a function or procedure on another machine, as if the function/procedure was executing locally. This is commonly used in client-server systems, where the client sends requests to the server for some service to be performed.

Question 20

​The term ____ describes middleware that stores the name and network address of distributed resources, responds to directory queries, accepts directory updates, and synchronizes replicated or distributed directory copies.
A) ​registration services
B) ​directory services
C) ​network services
D) ​configuration services

Accepted Answer

The description matches that of directory services, which store and manage information about network resources like servers, printers, and users. Registration services are a specific type of directory service that deal with registering new resources with the directory. Network services encompass a broader category of services related to network infrastructure, while configuration services deal with setting up and managing the configuration of systems and applications.
