Question 1

Which of the following terms best describes the maximum acceptable length of time a system can be non-responsive before it is restored?

Accepted Answer

Round-trip time best describes the maximum acceptable length of time a system can be non-responsive before it is restored, as it measures the time taken for a signal to be sent plus the time it takes for an acknowledgment of that signal to be received.

Question 2

Which of the following is an upgraded version of the SSL protocol and is a cryptographic protocol providing secure communications over computer networks?

Accepted Answer

TLS (Transport Layer Security) is the upgraded version of SSL (Secure Sockets Layer) designed to provide secure communications over computer networks.

Question 3

Which troubleshooting tool is developed by Solar Winds and is a large suite of network management tools for monitoring, discovery, and diagnostics?

Accepted Answer

Engineer's Toolset is developed by SolarWinds and offers a comprehensive suite of tools for network monitoring, discovery, and diagnostics, making it a versatile solution for network engineers.

Question 4

Which of the following protocols is used for advertisement and discovery of network services?

Accepted Answer

SSDP (Simple Service Discovery Protocol) is specifically designed for the advertisement and discovery of network services. It allows devices on a network to find each other and establish communication for data sharing and network services.

Question 5

Using the ifconfig command in Windows will produce results for network configuration information being used by the computer.

Accepted Answer

The correct command for viewing network configuration information in Windows is `ipconfig`, not `ifconfig`. `ifconfig` is used in Unix/Linux based systems.

Question 6

What command can be used on a Linux computer to view network configuration information being used by the computer?

Accepted Answer

The command "ifconfig" is used on Linux systems to view and configure the network interfaces, which includes displaying the current network configuration information.

Question 7

Which of the following Windows DHCP log file event IDs indicates that a new IP address was leased to a client?

Accepted Answer

Event ID 10 in Windows DHCP logs indicates that a new IP address has been leased to a client.

Question 8

What utility should you use in NetScan Tools if you wanted to determine information about the host computer?

Accepted Answer

The "Who Am I" utility is used to determine information about the host computer.

Question 9

Where do you look in a packet captured by Wireshark if you want to determine the RTO?

Accepted Answer

The Retransmission Timeout (RTO) is related to packet retransmissions in TCP connections. In Wireshark, the RTO can be inferred from the "TCP Analysis Flags" section, where events like retransmissions, lost segments, and out-of-order packets are indicated, which are relevant to understanding RTO behavior.

Question 10

Baseline refers to the amount of time it takes a packet to get from one point on the network to another.
Indicate the answer choice that best completes the statement or answers the question.

Accepted Answer

Baseline in networking typically refers to a standard or reference point for comparison, not the time it takes for a packet to travel between two points. The term for the time it takes a packet to travel from one point to another is "latency" or "ping time."

Question 11

To find out what's going on with a packet, you can use the Expert Information feature in Wireshark, which contains four different classes of information. Which of the following classes indicates "A very serious problem"?

Accepted Answer

The "Error" class in Wireshark's Expert Information feature indicates a very serious problem with a packet, suggesting that there is something significantly wrong that needs attention.

Question 12

What term is used to describe a globally distributed network of proxy servers deployed in multiple data centers?

Accepted Answer

A Content Delivery Network (CDN) is a system of distributed servers that deliver web content to a user based on the geographic locations of the user, the origin of the webpage, and a content delivery server. This effectively makes websites load faster by reducing the physical distance between the server and the user.

Question 13

Which of the following terms best describe a range of addresses from 169.254.0.0 to 169.254.255.255 that a Windows or Mac OS X computer assigns to its primary network interface when a DCHP server is unavailable?

Accepted Answer

This range is known as Automatic Private IP Addressing (APIPA). When a DHCP server is not available, devices within the network assign themselves an IP address from this range, allowing for local network communication.

Question 14

Round-trip time is more formally known as which of the following?

Accepted Answer

The answer of Round-trip time is more formally known as...

Question 15

Automatic Private IP Addressing (APIPA) is a range of addresses from 169.254.0.0 to 169.254.255.255 that a Windows or Mac OS X computer assigns to its primary network interface when a DHCP server is unavailable.

Accepted Answer

APIPA is a feature in Windows and Mac OS X operating systems that automatically assigns an IP address from the specified range (169.254.0.0 to 169.254.255.255) to the computer's network interface when it cannot obtain an IP address from a DHCP server.

Question 16

The command "ipconfig /renew" can be used to renew the IPv6 address for the specified adapter.

Accepted Answer

The "ipconfig /renew" command is used to renew the IPv4 address for the specified adapter. To renew an IPv6 address, the command "ipconfig /renew6" should be used instead.

Question 17

SSDP is a protocol used for advertisement and discovery of network services.

Accepted Answer

SSDP (Simple Service Discovery Protocol) is indeed used for the advertisement and discovery of network services on a local network.

Question 18

Where do you look in a packet captured by Wireshark to find the encrypted version of the username and password when the TLS protocol is in use?

Accepted Answer

The encrypted version of the username and password in a packet captured by Wireshark, when the TLS protocol is in use, would be found within the Secure Sockets Layer (SSL) portion of the packet. TLS operates within the SSL to encrypt data, including credentials.

Question 19

How many TCP retransmissions will Windows attempt by default before dropping all attempts?

Accepted Answer

The answer of How many TCP retransmissions will Windows attempt...

Question 20

Which of the following commands can be used to discover the IP address of the DNS server providing name services for a Linux computer?

Accepted Answer

The file /etc/resolv.conf contains the nameserver entries that a Linux system uses for DNS resolution, which includes the IP addresses of DNS servers.
