What is the function of DHCP in a network?
To automatically assign IP addresses to devices
To store digital certificates
To manage user passwords
To monitor physical network cables
DHCP (Dynamic Host Configuration Protocol) simplifies network configuration by automatically assigning IP addresses and other configuration details to devices. This automation streamlines network management compared to manual IP assignment.
Which of the following is a benefit of using fiber optic cables in networks?
Higher data transmission speeds
Easier installation
Lower initial costs
Lower bandwidth
Fiber optic cables support significantly higher data transmission speeds and offer greater bandwidth over longer distances. Although they provide superior performance, they tend to be more expensive and require specialized installation.
Hard
In the context of TCP/IP, what is the primary role of the Transmission Control Protocol (TCP)?
To ensure reliable data transmission with error checking
To encrypt data packets
To determine physical connection speed
To convert analog signals to digital
TCP is responsible for ensuring reliable communication by managing error checking, data sequencing, and flow control. The other options do not reflect TCP's purpose, which is to guarantee that data packets reach their destination accurately.
What is subnetting and why is it used in network management?
Dividing a network into smaller subnets to improve efficiency and security
Combining multiple networks into a single large network
Encrypting network traffic on a large scale
Converting physical addresses to IP addresses
Subnetting breaks a large network into smaller segments, making network management more efficient and increasing security by limiting broadcast domains. The other options describe actions that are not related to the concept of subnetting.
How does Network Address Translation (NAT) enhance network security?
By hiding internal IP addresses from external networks
By encrypting all outbound traffic
By increasing the speed of data transmission
By providing a dedicated IP for every device
NAT conceals internal IP addresses, making it harder for external parties to directly access devices within the local network. This layer of obscurity improves security, unlike encryption or increased speed, which are not functions of NAT.
Which protocol is used to remotely manage network devices securely over an untrusted network like the internet?
SSH (Secure Shell)
Telnet
RDP
FTP
SSH provides an encrypted channel for remote management, ensuring secure communication over untrusted networks. Telnet, by contrast, transmits data in plaintext, making it vulnerable to interception.
In a network using the OSI model, which layer is responsible for establishing, managing, and terminating connections between applications?
Session Layer
Transport Layer
Presentation Layer
Data Link Layer
The Session Layer manages the establishment, maintenance, and termination of communication sessions between applications. While the Transport Layer handles end-to-end data transmission, it is the Session Layer that specifically oversees these connection sessions.
