CompTIA Network+ N10-009 Passing Score

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.

A split-tunnel VPN allows certain traffic (e.g., cloud-based services) to bypass the VPN and go directly to the Internet. This reduces the amount of traffic that needs to traverse the company's VPN and Internet connection, conserving bandwidth and reducing costs. It also means that not all traffic is subject to the same level of inspection or filtering, which can improve performance for cloud-based services.References: CompTIA Network+ study materials.

A honeynet is a network of honeypots designed to attract and study attackers. Honeypots are decoy systems set up to lure cyber attackers and analyze their activities. A honeynet, being a collection of these systems, provides a broader view of attack methods and patterns, helping organizations improve their security measures.

When a DHCP server is installed and not enough IP addresses are provisioned, users may start experiencing network outages once the available IP addresses are exhausted. DHCP servers assign IP addresses to devices on the network, and if the pool of addresses is too small, new devices or those renewing their lease may fail to obtain an IP address, resulting in network connectivity issues.References: CompTIA Network+ study materials.
