Explanation
XDR solutions bring a proactive approach to threat detection and response. It delivers visibility across all data, including endpoint, network, and cloud data, while applying analytics and automation to address today's increasingly sophisticated threats. With XDR, cybersecurity teams can:
Identify hidden, stealthy, and sophisticated threats proactively and quickly Track threats across any source or location within the organization Increase the productivity of the people operating the technology Get more out of their security investments Conclude investigations more efficiently

Explanation
"Weaponization: Next, attackers determine which methods to use to compromise a target endpoint. They may choose to embed intruder code within seemingly innocuous files such as a PDF or Microsoft Word document or email message."

Explanation
Application (Layer 4 or L4): This layer loosely corresponds to Layers 5 through 7 of the OSI model.
Transport (Layer 3 or L3): This layer corresponds to Layer 4 of the OSI model.
Internet (Layer 2 or L2): This layer corresponds to Layer 3 of the OSI model.
Network Access (Layer 1 or L1): This layer corresponds to Layers 1 and 2 of the OSI model

Explanation
Routing Information Protocol (RIP) is an example of a distance-vector routing protocol that uses hop count as its routing metric. To prevent routing loops, in which packets effectively get stuck bouncing between various router nodes, RIP implements a hop limit of 15, which limits the size of networks that RIP can support. After a data packet crosses 15 router nodes (hops) between a source and a destination, the destination is considered unreachable.
