nmap is the tool that would help identify which ports are open on the remote file server. nmap stands for Network Mapper, which is a free and open-source tool that can perform various network scanning and discovery tasks. nmap can help identify which ports are open on a remote device by sending probes or packets to different ports and analyzing the responses. nmap can also provide information about the operating system, services, versions, firewalls, or vulnerabilities of the remote device. nmap can be useful for network administrators, security professionals, or hackers to monitor, audit, or attack network devices. References: [CompTIA Network+ Certification Exam Objectives], Nmap - Free Security Scanner For Network Exploration & Security Audits

A toner is a tool that generates an audible signal that can be traced by a probe. A network technician can use a toner to identify the appropriate patch panel port by connecting the toner to one end of the patch cord and using the probe to scan the patch panel until the signal is detected. A toner is the easiest way to identify the patch panel port when the patch panel is not labeled, as it does not require a laptop, a cable tester, or a visual fault locator. A toner can also be used to locate breaks or shorts in a cable, or to verify continuity.

• The question asks about the benefit of the spine-and-leaf network topology, which is a data center network design that consists of two layers of switches: the spine layer and the leaf layer. The spine layer interconnects all the leaf switches in a full-mesh topology, and the leaf layer connects to the servers and end devices1.
• The answer is stable network latency, which means the delay or time it takes for a packet to travel from one point to another in the network. In a spine-and-leaf topology, every leaf switch is the same number of hops away from any other leaf switch, which ensures consistent and predictable latency for the traffic between the servers and devices2. This is especially important for applications that require high performance and low latency, such as cloud computing, big data analytics, and virtualization3.
• Increased network security, simplified network management, and eliminated need for inter-VLAN routing are not the correct answers, because they are not the benefits of the spine-and-leaf topology. Increased network security depends on other factors, such as encryption, authentication, and firewall policies, not just the network topology. Simplified network management may be achieved by using automation and orchestration tools, but the spine-and-leaf topology itself may require more cabling and configuration than a traditional three-tier topology. Eliminated need for inter-VLAN routing is not a benefit, because inter-VLAN routing is still needed to communicate between different VLANs or subnets in the network, regardless of the topology. References:

Enhanced Interior Gateway Routing Protocol (EIGRP) uses bandwidth and delay as its primary metrics to determine the best path for routing traffic. EIGRP is an advanced distance-vector routing protocol, which is proprietary to Cisco systems, making it highly efficient in a variety of network designs. It can also utilize load, reliability, and maximum transmission unit (MTU) as additional metrics, but bandwidth and delay are the primary considerations in its composite metric calculation. Other protocols listed, such as RIP, OSPF, and BGP, use different metrics like hop count (RIP) and cost based on link state (OSPF), or make decisions based on path attributes and policy (BGP)​​.
