The correct answer is deploying a mesh network. A mesh wireless network uses multiple interconnected access points that automatically route traffic through the best available path. This ensures seamless coverage throughout a facility, even when users move between APs. Mesh APs can extend coverage without requiring each AP to be directly wired, making them ideal for large or hard-to-wire environments.
A). Ad hoc access points are peer-to-peer connections and cannot provide enterprise-grade continuous coverage.
B). Ethernet drops provide wired connectivity but do not solve wireless coverage issues.
D). Changing the frequency (from 2.4 GHz to 5 GHz or vice versa) may reduce interference but will not guarantee building-wide seamless connectivity.
Mesh networks are particularly effective in environments with roaming devices (smartphones, tablets, handheld scanners) and ensure that there are no dead spots, thereby delivering continuous wireless access.

Port 443 is used by HTTPS (Hypertext Transfer Protocol Secure), a secure version of HTTP that uses SSL
/TLS to encrypt the communication between a client and server. This ensures confidentiality and integrity of data in transit. The document states:
"Port 443 is the default port for HTTPS, which secures HTTP traffic using SSL/TLS, providing encryption and secure identification of web servers."

Comprehensive and Detailed Explanation (aligned to N10-009):
A broadcast message is delivered to all nodes in a broadcast domain (e.g., ARP requests).
A). Unicast is one-to-one.
C). Multicast is one-to-many but only to subscribed members.
D). Anycast is one-to-one-of-many, sending to the nearest node.

Speed Mismatches: If NICs are set to different speeds (e.g., 100 Mbps on one side and 1 Gbps on the other), performance will degrade. Ensuring consistent speed settings between devices is crucial for optimal performance.
Load balancer settings (B): Applies to server load distribution, not endpoint speed.
Flow control settings (C): Can affect performance but is secondary to speed mismatches.
Infrastructure cabling grade (D): Relevant if the cables are unsuitable for gigabit speeds, but speed settings should be checked first.
