A

Tracert

21
Q

Which command in MS Windows displays a table consisting of IP addresses and their resolved physical addresses?

A

arp -a

22
Q

Which of the following command-line commands in MS Windows are used to display the contents of a routing table?

A

route print

netstat -r

23
Q

Which netstat parameter allows to display the names of applications and executable file components that are accessing the network?

A

-b

24
Q

Which of the following commands displays the name of the current computer a user is connected to?

A

Hostname

25
Q

Which of the following answers refers to a command-line packet capturing utility?

A

Tcpdump

26
Q

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

A

Nmap

27
Q

An estimated measurement of the power level that a wireless client device is receiving from an Access Point (AP), or router is referred to as?

A

RSSI.

28
Q

Which of the following terms refers to a measured radiated output power of an antenna in a single direction?

A

EIRP.

EIRP is Effective Isotropic Radiated Power and is the amount of power a theoretical isotropic antenna would emit to produce the same signal strength as the actual antenna in a direction.

29
Q

In computer networking, the term “Collision” refers to a situation in which two or more demands are made simultaneously on an equipment that can handle only one request at any given moment. In wired and wireless networks, preventing collisions translates into verifying the absence of other traffic on a shared medium before transmitting and the network protocol used for that purpose is known as Carrier Sense Multiple Access (CSMA). Depending on the network type, variations of the protocol include Carrier Sense Multiple Access / Collision Avoidance (CSMA/CA) network access method used in wired networks, and Carrier Sense Multiple Access / Collision Detection (CSMA/CD) network access method used in wireless networks.

A

False.

30
Q

Which of the following protocols provide protection against broadcast storms?

A

STP.

STP is Spanning Tree Protocol and is a network protocol that builds a loop-free topology for Ethernetworks.

31
Q

The term “Asymmetric routing” refers to a network configuration scenario in which packets are sent and received via different network paths?

A

True.

32
Q

Which of the following protocols provide protection against switching loops?

A

STP.

33
Q

Spanning Tree Protocol (STP) prevents?

A

Switching loops and broadcast storms.

34
Q

Which of the following mechanisms can be used to mitigate routing loops?

A

Maximum hop count.

TTL.

Split Horizon.

Route Poisoning.

Hold Down Timer.

35
Q

What is the fastest way to validate a digital certificate?

A

OCSP.

OCSP is Online Certificate Status Protocol.

39
Q

What are the Linux network configuration commands?

A

ifconfig
ip addr
nmcli -o

40
Q

Whare are collision domains?

A

Switches isolate collision domains (networks segments where devices can transmit simultaneously). Each switch port is a separate collision domain.

41
Q

What is the effect of combining switch ports as access ports with the same logical bridge?

A

This puts these ports in the same broadcast domain allowing hosts attached to them to communicate with each other.

42

In Windows, DNS client commands/switches are available via a CLI using the command?

A

ipconfig
