CompTIA Network+ Practice Test 21

traceroute

A Linux command-line utility for displaying intermediary points (routers) the IPv4 packet is passed through on its way to another network node is known as: nbtstat traceroute netstat tracert

netstat

A command-line utility in MS Windows used for displaying protocol statistics and current TCP/IP network connections is called: tracert traceroute netstat nslookup

tracert

A network command-line utility in MS Windows that tracks and displays the route taken by IPv4 packets on their way to another host is called: ping traceroute nslookup tracert

False

Domain information groper (dig) and nslookup are command-line tools used for DNS queries. Both utilities are available on Windows and Linux. Of the two, nslookup is the preferred tool on UNIX-like systems; dig is the default DNS query tool for MS Windows. True False

Repeater

In computer networking, the term "Attenuation" refers to a loss in signal strength during transmission caused by increasing distance and obstacles encountered on the signal path. The problem of attenuating circuit on the network can be solved by adding a device that boosts the signal strength. This type of device is known as: Repeater Media converter Inverter Load balancer

Crosstalk, EMI

Shielded Twisted-Pair (STP) cabling reduces what kind of interference? (Select 2 answers) Jitter Signal attenuation Crosstalk EMI Signal latency

IP to MAC

The arp command can be used to perform what kind of resolution? IP to FQDN MAC to IP IP to MAC FQDN to IP

True

The general feature of all twisted-pair cabling types is that wires inside the cable are grouped into pairs and wires in each pair are twisted around each other to reduce signal interference from adjacent wire pairs (effect known as crosstalk). True False

ifconfig

What is the name of a Linux command-line utility that can be used to display TCP/IP configuration settings? ifconfig netstat nslookup ipconfig

ipconfig

What is the name of a Windows command-line utility that can be used to display TCP/IP configuration settings? ifconfig nslookup ipconfig netstat

arp -a

Which command in MS Windows displays a table consisting of IP addresses and their resolved physical addresses? arp -e netstat -n nslookup arp -a

route print

Which command-line command in MS Windows is used to display the contents of a routing table? netstat -a route print ipconfig /all

/all

Which ipconfig parameter allows to view the physical address of a Network Interface Card (NIC)? -S srcaddr /all -i address eth_addr

-a

Which netstat parameter allows to display all active TCP connections and the TCP/UDP ports on which the computer is listening? -a -p -e -r

-b

Which netstat parameter allows to display the names of applications and executable file components that are accessing the network? -a -n -b -p

pathping

Which network command-line utility in MS Windows combines the features of ping and tracert? nbtstat pathping nslookup netstat

Linux command-line tool, Packet filtering utility

Which of the answers listed below refer to iptables? (Select 2 answers) Packet capturing utility MS Windows command-line tool Packet tracing utility Linux command-line tool Packet filtering utility

Which of the answers listed below refers to an ipconfig command parameter used for displaying the full TCP/IP configuration information for all adapters? -a /? /all /-a

tcpdump

Which of the following answers refers to a command-line packet capturing utility? netcat Zenmap tcpdump Nmap

ipconfig /release, ipconfig /renew

Which of the following command-line commands in MS Windows are used for resetting the DHCP configuration settings for all adapters? (Select 2 answers) ifconfig eth0 down ipconfig /release ifconfig eth0 up ipconfig /renew

Nmap

Which of the following command-line tools is used for discovering hosts and services on a network? Nmap netcat Zenmap tcpdump

nslookup

Which of the following network administration command-line utilities can be used for DNS queries? tracert nslookup ping pathping

-r

Which of the netstat utility parameters listed below allows to display the contents of an IP routing table? -a -p -e -r

nslookup

Which of the software tools listed below allows for obtaining a domain name to IP address mapping? netstat nslookup tracert pathping

ping, Packet analyzer, tracert/traceroute

Which of the tools listed below can provide information on network latency problems? (Select 3 answers) ping Packet analyzer Network mapper tracert/traceroute netstat
