Clientless VPNs allow users to access the company network from home without installing additional software. They use web browsers for connectivity.

Speed is the maximum rate at which data can be transferred, and should be checked first if a user complains about slow wireless speeds.

The Presentation layer formats data for display or transmission, including tasks like data translation, compression, and encryption.

An audit and assessment report is crucial for understanding the performance and security of an organization’s network over time, providing insights into compliance and areas for improvement.

The Transport layer is responsible for segmentation, flow control, and error control, ensuring complete data transfer.

iperf is used for active network performance measurement.

The Network layer is responsible for packet forwarding and routing, determining the best path for data to travel across a network.

A Wide Area Network (WAN) is suitable for connecting offices located in different countries, providing a network that spans large geographical areas.

The Physical layer is responsible for the transmission of raw bitstreams over a physical medium, such as cables and switches.

Managed switches offer advanced features such as the ability to prioritize network traffic, create VLANs, and monitor network performance, which are essential for ensuring that critical applications receive the bandwidth they need. Unmanaged switches, routers, and hubs do not offer this level of control.

A proxy server is used to cache frequently accessed web pages and reduce bandwidth usage on the network.

AP association time could be causing the delay in connecting to the wireless network.

Private VLANs allow for the creation of isolated sub-networks within a larger network.

Smart lockers contribute to physical security by providing secure storage for sensitive items and controlling access through electronic locks and authentication.

CRCs are used to detect errors in transmitted data by verifying the integrity of the data, ensuring that data has not been corrupted during transmission.

DNS caching temporarily stores DNS query results to improve resolution times and reduce the load on DNS servers.

Locking cabinets enhance physical security in a data center by preventing unauthorized access to servers and other critical equipment, ensuring that only authorized personnel can access these resources.

802.11ac (WiFi 5) offers higher throughput compared to 802.11g, 802.11n, and 802.11b, making it the best choice for applications requiring high bandwidth, such as video conferencing.

Kerberos provides secure authentication and communication over a network using tickets.

Hypertext Transfer Protocol (HTTP) uses port 80 to deliver web pages over an unencrypted connection.

AAAA records in DNS are used to map a domain name to an IPv6 address.

A multimeter is used to measure current, voltage, and resistance in electrical circuits.

HTTPS (HTTP over SSL/TLS) uses port 443 for secure web browsing.

Power over Ethernet (PoE) dynamically distributes power to devices such as IP cameras and access points, simplifying installations and reducing the need for additional power supplies.
