IPSec is a protocol that provides secure communication between two networks or hosts over an untrusted network, such as the Internet. IPSec uses encryption and authentication to protect the data from eavesdropping, tampering, and replay attacks. IPSec also supports pre-shared key (PSK) as one of the methods for initial authentication between the peers

This is the port number for HTTPS, which stands for Hypertext Transfer Protocol Secure. HTTPS is a secure version of HTTP, which is the protocol used to communicate between web browsers and web servers. HTTPS encrypts the data sent and received using SSL/TLS, which are cryptographic protocols that provide authentication, confidentiality, and integrity. HTTPS is commonly used for online transactions, such as banking and shopping, where security and privacy are important

No more patches or bug fixes are available indefinitely. This indicates that a computer has reached end-of-support, which means that the manufacturer or vendor of the hardware or software no longer provides technical assistance, updates, or security fixes for the product12. This can expose the computer to potential security risks and compatibility issues with newer technologies

Jumbo frames are Ethernet frames that have a payload size greater than the standard 1500 bytes.

Jumbo frames can carry more data in each frame, which reduces the overhead and improves the throughput and efficiency of data transmission. Jumbo frames are commonly used in storage area networks (SANs), where large amounts of data need to be transferred between servers and storage devices

A service-level agreement (SLA) is a document that states what the minimum performance expectations are within a network, such as uptime, throughput, latency, and security. An SLA is usually signed between a service provider and a customer, and it specifies the penalties or remedies if the service level is not met

A hybrid cloud deployment model is a combination of on-premise and cloud solutions, where some resources are hosted in-house and some are hosted by a cloud provider. A hybrid cloud model can offer the benefits of both public and private clouds, such as scalability, cost-efficiency, security, and control12. A hybrid cloud model can also reduce the impact for users, as they can access the key services from the on-site data center and the enterprise services from the cloud

This is the most likely cause of the user's connection issues, because the ARP table of the switch shows that there are two devices with the same IP address of 192.168.1.10, but different MAC addresses. This indicates that there is an IP address conflict on the network, where two devices are trying to use the same IP address. This can cause intermittent connectivity issues, as the switch may not be able to forward packets to the correct destination .

Port 25, by default, should be reserved for SMTP traffic to allow for a new cloud-based email server.

SMTP stands for Simple Mail Transfer Protocol, which is a network protocol that enables email communication between mail servers and clients. SMTP uses port 25 as its default port for sending and receiving email messages over TCP/IP networks. A cloud-based email server is an email server that is hosted on a cloud service provider's infrastructure, rather than on-premise or in-house. A cloud-based email server can offer advantages such as scalability, reliability, security, and cost-effectiveness. To allow for a new cloud-based email server, a firewall should be configured to open port 25 for SMTP traffic.
