CCNA Exam: Trivia! MCQ Quiz

In FTP transactions, the pull method is used by the FTP client to download files from an FTP server. This means that the client initiates the transfer by requesting the file from the server and pulling it down to their own device. This is in contrast to the push method, where the server would actively send the file to the client. Therefore, the statement "True" is correct.

The correct answer is the application layer. This layer is responsible for providing services to the end-user, such as email, web browsing, and file transfer. It interacts directly with the user and uses protocols like HTTP, FTP, and SMTP to facilitate communication between applications running on different devices. The application layer is the highest layer in the TCP/IP model and is closest to the end-user in terms of functionality and interaction.

The correct answer is nslookup. Nslookup is a command-line tool used to manually query a DNS server and resolve a specific host name. It allows users to enter a domain name and retrieve the corresponding IP address or other DNS records associated with that domain. This can be helpful in troubleshooting network connectivity issues or verifying DNS configurations.

The session layer, application layer, and presentation layer of the OSI model provide similar network services to those provided by the application layer of the TCP/IP model. These layers are responsible for managing communication sessions, providing network services to applications, and formatting data for presentation respectively.

DHCP is preferred for use on large networks because it is a more efficient way to manage IP addresses than static address assignment. With DHCP, IP addresses can be dynamically assigned to devices on the network, eliminating the need for manual configuration. This saves time and reduces the chances of errors that can occur with manual assignment. Additionally, DHCP allows for automatic IP address renewal, making it easier to handle a large number of devices on the network without the need for constant manual intervention.

A home router is most likely to provide dynamic IP addressing to clients on a home network. A home router acts as a central hub for the network, connecting multiple devices and allowing them to communicate with each other and access the internet. It typically includes a built-in DHCP (Dynamic Host Configuration Protocol) server, which automatically assigns IP addresses to devices on the network. This allows devices to join and leave the network without manual configuration, making it convenient for home users. A dedicated file server, an ISP DHCP server, and a DNS server are not typically found in a home network setup and are less likely to provide dynamic IP addressing.

To access a website like http://www.cisco.com, the host needs to have the correct DNS server configured. The DNS server is responsible for translating domain names (like www.cisco.com) into IP addresses that the host can understand. Additionally, the host needs to have the correct default gateway configured. The default gateway is the IP address of the router that connects the host to the rest of the network. It is responsible for routing the network traffic to the appropriate destination. Therefore, both the DNS server and the default gateway must be correctly configured on the host to allow access to http://www.cisco.com.

A DNS MX record contains information about the domain name mapped to mail exchange servers. This means that it specifies the domain name that should receive email messages for a particular domain. MX records are used in the process of delivering email to the correct mail servers.

In a client-server network, there is a dedicated server that provides services and resources to the client devices. This means that the server is solely responsible for managing and distributing network resources, such as files, printers, and databases, while the client devices, such as workstations, laptops, or mobile devices, rely on the server to access these resources. Each client device can act as a client by requesting and receiving services from the server, but they do not have the same level of responsibility as the server. Therefore, the statement "The network includes a dedicated server" is true in the context of a client-server network.

Gnutella is a common protocol that is used with peer-to-peer applications such as Wireshare, Bearshare, and Shareaza. Gnutella allows users to search for and share files directly with other users on the network, without the need for a central server. It enables decentralized file sharing and communication between peers, making it a popular choice for peer-to-peer applications. Ethernet, POP, and SMTP are not protocols specifically designed for peer-to-peer file sharing, making Gnutella the correct answer.

The networking model in use is peer-to-peer (P2P). In this model, all computers on the home network are considered equal and can act as both clients and servers. Each computer can directly communicate and share resources, such as the printer, with other computers on the network without the need for a central server. This allows multiple computers to use the printer without relying on a single master or slave device.

POP3 (Post Office Protocol 3) is a protocol that is commonly used to transfer messages from an email server to an email client. It allows the email client to retrieve emails from the server and download them to the client's device. SMTP (Simple Mail Transfer Protocol) is used for sending emails from the client to the server, while POP3 is used for downloading emails from the server to the client. SNMP (Simple Network Management Protocol) is used for network management, and HTTP (Hypertext Transfer Protocol) is used for transferring data over the internet.

SMB clients can establish a long-term connection to the server, which means that once the connection is established, it can be maintained for an extended period of time without the need for frequent reconnections. This allows for continuous and uninterrupted access to the server, making it more convenient for users who require ongoing access to files and resources. In contrast, FTP typically uses a stateless connection where each file transfer requires a new connection to be established, resulting in more overhead and potential interruptions in the connection.
