71. Which of the following is used to list all of the hops from a starting point to a final destination?

Explanation

Tracert is used to list all of the hops from a starting point to a final destination. It is a command-line tool that traces the route taken by packets across an IP network. By sending a series of ICMP Echo Request messages with varying Time-To-Live (TTL) values, tracert determines the path that packets take to reach the final destination. It provides detailed information about each hop, including the IP address, hostname, and response time.

75. Which of the following provides NetBIOS name to IP address resolution?

Explanation

WINS (Windows Internet Name Service) provides NetBIOS name to IP address resolution. NetBIOS is an older networking protocol used by Windows computers to communicate with each other. WINS acts as a central database that maps NetBIOS names to IP addresses, allowing computers to locate and communicate with each other on the network. DHCP (Dynamic Host Configuration Protocol) is responsible for assigning IP addresses to devices on a network, DNS (Domain Name Services) translates domain names to IP addresses, and NAT (Network Address Translation) allows multiple devices to share a single public IP address.
