Comprehensive and Detailed Explanation From Exact Extract:
The greatest advantage of network segmentation is the creation of security zones, which isolate systems into separate logical or physical network sections. According to CompTIA Security+ SY0-701, segmentation is a foundational security architecture practice used to reduce the attack surface, restrict lateral movement, enforce least privilege, and contain breaches. By dividing the network into zones-such as DMZ, internal, restricted, and guest-administrators can apply tailored access controls, firewall rules, IDS/IPS placement, and monitoring boundaries.
Segmentation provides defense-in-depth by preventing attackers from reaching critical systems even if they compromise a less-secure device. It also limits broadcast domains and improves traffic visibility. End-to-end encryption (A) protects confidentiality but is unrelated to segmentation. Decreased resource utilization (B) is not a primary benefit. Enhanced endpoint protection (C) applies to host controls, not network topology.
Configuration enforcement (D) is a benefit of centralized management, not segmentation.
Therefore, the correct answer is Security zones, the core outcome and highest-value advantage of segmentation.

The best answer is C. Software is migrated to a cloud that offers increased flexibility in its updates.
A change management policy defines how changes are requested, reviewed, approved, tested, documented, and implemented. When an organization migrates software to a cloud environment that supports more dynamic, frequent, or automated updates, the change management process may need to be revised to reflect the new operational model.
Cloud environments often introduce:
faster deployment cycles
infrastructure as code
automated updates
continuous integration and continuous delivery
different approval and rollback processes
These changes can significantly affect how the organization governs system changes, so revising the policy is likely necessary.
Why the other options are incorrect:
A). An engineer adds a new feature to the production service.This is an example of a change that should follow policy, not necessarily a reason to revise the policy itself.
B). A production server continuously runs at its maximum load.This is more of a performance or capacity issue than a direct reason to revise change management policy.
D). A legacy server lacks support for new regulatory requirements.This points more toward compliance remediation or system replacement, not specifically revising change management policy.
From the SY0-701 perspective, major shifts in how systems are updated and maintained, especially through cloud adoption, are strong reasons to update change management governance. Therefore, C is correct.

A hash is an algorithm used to verify data integrity by generating a fixed-size string of characters from input data. If even a single bit of the input data changes, the hash value will change, allowing users to detect any modification to the data. Hashing algorithms like SHA-256 and MD5 are commonly used to ensure data has not been altered.
