C480 - Chap 10

Which of the following commands is used on a UNIX host to generate information about each router hop along the path from a source to a destination?

traceroute

What option would you specify after the ipconfig command to display a Windows PC's DNS server's IP address?

/all

Consider the following output: C:\> arp -a Interface: 172.16.202.128 --- 0xb Internet Address Physical Address Type 172.16.202.2 00-50-56-fd-65-2c dynamic 172.16.202.255 ff-ff-ff-ff-ff-ff static 224.0.0.22 01-00-5e-00-00-16 static 224.0.0.252 01-00-5e-00-00-fc static 255.255.255.255 ff-ff-ff-ff-ff-ff sta What is the MAC address corresponding to the IP address of 172.16.202.2?

00-50-56-fd-65-2c

ipconfig command

A Microsoft Windows command that can be used to display IP address configuration parameters on a PC. In addition, if DHCP is used by the PC, the ipconfig command can be used to release and renew a DHCP lease, which is often useful during troubleshooting.

tracert command

A Microsoft Windows-based command that displays every router hop along the path from a source host to a destination host on an IP network. Information about a router hop can include such information as the IP address of the router hop and the round-trip delay of that router hop.

traceroute command

A UNIX command that displays every router hop along the path from a source host to a destination host on an IP network. Information about the router hop can include the IP address of the router hop and the round-trip delay of that router hop.

route command

Can add, modify, or delete routes in the IP routing table of Microsoft Windows and UNIX hosts. In addition, the route command can be used to view the IP routing table of Microsoft Windows hosts.

netstat command

Can display a variety of information about IP-based connections on a Windows or UNIX host.

nslookup command

Can resolve a FQDN to an IP address on Microsoft Windows and UNIX hosts.

dig command

Can resolve a FQDN to an IP address on UNIX hosts.

host command

Can resolve a FQDN to an IP address on hosts.

nbtstat command

Displays NetBIOS information for IP-based networks. The nbt prefix of the nbtstat command refers to NetBIOS over TCP/IP, which is called NBT (or NetBT). This command can, for example, display a listing of NetBIOS device names learned by a Microsoft Windows-based PC.

What protocol is used by the ping command?

ICMP

ping command

One of the most commonly used command-line commands. It can check IP connectivity between two network devices. Multiple platforms (for example, routers, switches, and hosts) support the ping command.

Which of the following UNIX commands is primarily used to resolve a fully-qualified domain name (FQDN) to an IP address and lacks an interactivity mode (that is, the entire command and all of the appropriate parameters are entered with a single command)?

dig

ifconfig

Which of the following UNIX commands can be used to invoke a UNIX syntax reference?

man

Which of the following Windows commands enables you to display NetBIOS over TCP/IP information?

nbtstat

While more than one of the following Microsoft Windows® commands can be used to resolve a fully-qualified domain name (FQDN) to an IP address, identify the command whose primary purpose is to resolve a FQDN to an IP address (for example, to determine if a Domain Name System (DNS) record is correct).

nslookup

Which of the following UNIX commands can be used to check FQDN-to-IP address resolution? (Choose three.)

nslookup, dig, host

Which of the following commands would you issue on a UNIX host to send five ICMP echo messages to a device with an IP address of 10.1.1.1?

ping -c 5 10.1.1.1
