Question 1

​With P2P architecture, there are more potential bottlenecks and points of failure.

Accepted Answer

In P2P (Peer-to-Peer) architecture, the workload is distributed among multiple peers rather than relying on a centralized server, reducing the number of bottlenecks and points of failure.

Question 2

​LDAP defines several standard container object types, including Country (C), Organization (O), and Organizational Unit (OU).

Accepted Answer

LDAP does define several standard container object types, including Country (C), Organization (O), and Organizational Unit (OU).

Question 3

​HTTPS is the "secure" version of HTTP

Accepted Answer

HTTPS stands for Hypertext Transfer Protocol Secure and is a combination of HTTP and SSL/TLS protocol that provides encryption and authentication to secure the data transfer between the server and the client. Therefore, it is considered as the "secure" version of HTTP.

Question 4

​A fully qualified DN specifies a complete path from a directory root node through one or more container objects to a specific object.

Accepted Answer

This statement is true. A fully qualified DN (Distinguished Name) contains all the necessary information to identify a specific object in an LDAP directory, including the directory root node, one or more container objects, and the specific object itself.

Question 5

​Every IP packet carries the destination node's IP address.

Accepted Answer

This is true. Every IP packet contains both a source and destination address in its header, allowing it to be routed through the internet to its intended recipient.

Question 6

​There is a standard objectclass or attribute name for all entities and resources common to most directories, such as people and shared printers.

Accepted Answer

In directory services, such as LDAP, while there are common object classes and attributes (e.g., `inetOrgPerson` for people), there is no single standard object class or attribute name that applies to all entities and resources across different directories. The schema can vary significantly depending on the specific implementation and the needs of the organization.

Question 7

​Active Directory is based on LDAP and DNS, so it responds to standard LDAP information requests and uses LDAP concepts, such as objectclasses and OUs, to store and organize directory information hierarchically.

Accepted Answer

Active Directory is indeed based on LDAP and DNS, and uses LDAP concepts such as objectclasses and OUs to store and organize directory information hierarchically.

Question 8

Three-layer architecture simplifies distributing or replicating application software across a network.

Accepted Answer

Three-layer architecture separates the user interface, application logic, and database management into separate layers, making it easier to distribute or replicate the software across a network.

Question 9

​Advantages of P2P architecture include improved scalability and reducing the number of computer and network connections needed to support an application.

Accepted Answer

P2P architecture allows for distributed computing and resource sharing, leading to improved scalability. It also reduces the reliance on a centralized server, which can reduce the number of computer and network connections needed to support an application.

Question 10

​A server hosts a single service or resource.

Accepted Answer

A server can host multiple services or resources, depending on its configuration and capabilities.

Question 11

​HTML extends XML to describe the structure, format, and content of documents.

Accepted Answer

HTML is not an extension of XML; rather, both HTML and XML are derived from SGML (Standard Generalized Markup Language). HTML is designed for web pages, while XML is a specification for creating custom markup languages.

Question 12

​The client/server architectural model can be applied in many ways.

Accepted Answer

The client/server architectural model can be applied in various domains, including networking, web applications, databases, and more. Therefore, the statement is true.

Question 13

​Every network attached to the Internet has at least one server designated as a DNS server.

Accepted Answer

Not every network attached to the Internet requires a designated DNS server within the network itself; devices can be configured to use external DNS servers provided by ISPs or third-party services.

Question 14

​In large networks, responsibility for maintaining directory content and answering queries is centralized to a few individuals who manage the network.

Accepted Answer

In large networks, responsibility for maintaining directory content and answering queries is often distributed across multiple servers and locations to ensure efficiency, reliability, and scalability.

Question 15

A server manages system resources and provides access to these resources through a well-defined communication interface.​

Accepted Answer

This statement correctly defines the role and purpose of a server.

Question 16

​A port number is an unsigned 24-bit integer

Accepted Answer

A port number is an unsigned 16-bit integer, which means it has a range of 0-65535.

Question 17

​Static connections are easy to initialize and maintain.

Accepted Answer

Static connections, once established, do not adapt to network changes or failures as dynamically as other types of connections, making them more complex to maintain over time, especially in environments where network configurations change frequently.

Question 18

​As OSs have evolved, they have incorporated fewer and fewer middleware functions.

Accepted Answer

As OSs have evolved, they have incorporated more middleware functions to provide better support for applications and services.

Question 19

​An operating system's primary role is to manage hardware, software, and data resources.

Accepted Answer

An operating system is responsible for managing the hardware, software and data resources of a computer system. It acts as an interface between the user and the computer hardware, providing a platform for applications to run and interact with the hardware. It also provides various services such as memory management, process management, file management, security and network communication.

Question 20

​LDAP queries contain plaintext characters and the syntax is simple and straight forward.

Accepted Answer

The answer of ​LDAP queries contain plaintext characters and the...
