CompTIA Network+ N10-009 Exam Dumps

If the administrator is concerned a new discovery tool could disrupt operations, the safest option is to configure scheduled scans. Network+ (N10-009) operations guidance emphasizes minimizing impact by running potentially noisy tasks (discovery, vulnerability checks, inventory scans) during defined maintenance windows or off-peak hours. A scheduled scan allows controlled timing, predictable load, and easier coordination with change management, monitoring, and support teams. This reduces the risk of saturating links, overwhelming devices with queries, or triggering alerts during business-critical periods.

Ad hoc scanning is on-demand and may occur at any time, which increases the chance of disruption if run during peak usage. Authenticated versus unauthenticated describes whether the scanner uses credentials to log into systems for deeper visibility; that choice affects depth and accuracy, but it doesn’t directly address when scanning occurs to reduce business impact. An authenticated scan can still be disruptive if run at the wrong time, and an unauthenticated scan can still generate significant traffic. Since the key concern is operational disruption, controlling scan timing via scheduled scans is the best mitigation.

When traceroute shows asterisks (timeouts) instead of IP addresses or hostnames, it may indicate that intermediate routers are dropping ICMP packets. However, performing an nslookup will reveal the IP address associated with the domain name, confirming that DNS resolution is correct and helping identify the path to the target server. The document states:

“nslookup is used to query DNS servers to retrieve IP address information associated with a domain name, which helps confirm DNS resolution is working correctly even when traceroute results show timeouts.”

Border Gateway Protocol (BGP) is the primary protocol used to route traffic on the public internet. It allows ISPs and large networks to exchange routing information, making it an Exterior Gateway Protocol (EGP).

Breakdown of Options:

A. BGP – Correct answer. Used for internet routing and exchanges routing information between ISPs.

B. OSPF – An Interior Gateway Protocol (IGP) used for routing within an autonomous system (not the public internet).

C. EIGRP – Cisco’s proprietary IGP, used within private networks, not the public internet.

D. RIP – An older distance-vector protocol, not scalable for the internet.

The switch with the lowest STP priority becomes the root bridge.In the given table, core-sw01 has the lowest priority value of 24576. Therefore, it will be elected as the root bridge in the Spanning Tree Protocol topology.
