CompTIA Network+ N10-009 Exam Dumps

Band steering allows wireless access points to automatically direct capable devices to the 5GHz band, which typically has higher throughput and less interference than the 2.4GHz band, improving performance. The document confirms:

“Band steering helps balance wireless client loads by steering dual-band capable devices to the 5GHz band, which offers higher speeds and less channel congestion than 2.4GHz.”

To change where the outside DNS records are hosted, the network administrator needs to update the NS (Name Server) records at the domain registrar. NS records specify the authoritative name servers for a domain, directing where DNS queries should be sent.

NS (Name Server) Records: These records indicate the servers that are authoritative for a domain. Changing the NS records at the registrar points DNS resolution to the new hosting provider.

SOA (Start of Authority): Contains administrative information about the domain, including the primary name server.

PTR (Pointer) Records: Used for reverse DNS lookups, mapping IP addresses to domain names.

CNAME (Canonical Name) Records: Used to alias one domain name to another, not relevant for changing DNS hosting.

Ping sends ICMP Echo Request packets and waits for Echo Replies to verify host reachability and measure round-trip time.

A. tcpdump captures packets but does not test reachability.

B. netstat displays open ports and network sessions.

C. nslookup queries DNS servers for name resolution.

Wi-Fi 6E is the best choice for high-density environments, such as a university campus. It:

Supports more devices with OFDMA (Orthogonal Frequency-Division Multiple Access)

Uses the 6GHz band, reducing congestion

Provides faster speeds and lower latency

This makes Wi-Fi 6E ideal for large networks with high-bandwidth demands, like those in a university setting.

Breakdown of Options:

A. Bluetooth – Used for short-range, low-power connections, not large-scale wireless networks.

B. Wi-Fi 6E – ✅ Correct answer. Designed for high-density environments, improving speed and efficiency.

C. 5G – Used for mobile networks, but not ideal for campus-wide local wireless infrastructure.

D. LTE – Used for cellular data, not for campus-wide Wi-Fi.
