A company is setting up a new network and wants to ensure that its network devices can communicate with each other efficiently. The network administrator decides to use a protocol that will allow devices to automatically assign IP addresses to newly connected devices. Which of the following protocols is the network administrator most likely to use?
Answer: A — The correct answer is A) Dynamic Host Configuration Protocol (DHCP) because DHCP is a protocol that allows devices to automatically assign IP addresses to newly connected devices. This protocol is commonly used in networks to simplify the process of assigning IP addresses and other network settings. The other options are incorrect because DNS is used for resolving domain names to IP addresses, HTTP is used for transferring data over the web, and SMTP is used for sending email.
A company is setting up a new network and wants to ensure that devices can automatically obtain IP addresses. Which of the following protocols should they use to achieve this?
Answer: D — DHCP (Dynamic Host Configuration Protocol) is the correct answer because it is a protocol used for assigning IP addresses and other network settings to devices on a network. HTTP (Hypertext Transfer Protocol) is a protocol used for transferring data over the internet, FTP (File Transfer Protocol) is a protocol used for transferring files over a network, and TCP (Transmission Control Protocol) is a protocol used for ensuring reliable data transfer, but none of these protocols are used for automatically assigning IP addresses.
A company is setting up a new network and needs to choose a protocol for its employees to remotely access files from home. The protocol must ensure that the data being transferred is secure and encrypted. Which of the following protocols would be the most suitable choice?
Answer: B — SFTP is the correct answer because it provides a secure and encrypted way to transfer files over a network. FTP is insecure as it transmits passwords and data in plain text, HTTP is primarily used for web browsing and not designed for secure file transfer, and Telnet is used for remote access but does not encrypt data. Therefore, SFTP is the most suitable choice for secure file transfer.
A company has a network that uses both TCP/IP and IPX/SPX protocols. The network administrator wants to ensure that all devices on the network can communicate with each other. Which of the following protocols would be used to translate between TCP/IP and IPX/SPX?
Answer: D — NetBIOS (Network Basic Input/Output System) is a protocol that allows devices with different network protocols (such as TCP/IP and IPX/SPX) to communicate with each other. It provides a layer of abstraction between the network protocols and the applications, allowing devices to communicate regardless of the underlying protocol. HTTP (Hypertext Transfer Protocol) is a protocol used for transferring data over the web, FTP (File Transfer Protocol) is a protocol used for transferring files, and DNS (Domain Name System) is a protocol used for resolving domain names to IP addresses. These protocols do not provide translation between TCP/IP and IPX/SPX.
A company is setting up a new network and needs to choose a protocol for communication between devices. They want a protocol that will allow devices to assign themselves an IP address without the need for a server. Which protocol should they use?
Answer: B — APIPA (Automatic Private IP Addressing) is a protocol that allows devices to assign themselves an IP address without the need for a server. DHCP (Dynamic Host Configuration Protocol) requires a server to assign IP addresses. HTTP (Hypertext Transfer Protocol) and FTP (File Transfer Protocol) are protocols used for transferring data over the internet, not for assigning IP addresses. Therefore, APIPA is the correct answer.
