Question 1

A ____ is an indicator of a quantity of an object that can be measured in some unit, such as percent, bytes sent per second, or number of reset connections, depending on what is appropriate to the object.
A)flag
B)counter
C)marker
D)delimiter

Accepted Answer

A counter is a type of measurement that tracks specific events or values and displays them in a numerical form. Examples of counters in computing include CPU usage, network traffic, and disk space usage.

Question 2

As defined in System Monitor, a(n)____ is a running line chart of the object that shows distinct peaks and valleys.
A)graph
B)histogram
C)report
D)image

Accepted Answer

A running line chart, also known as a line graph, is a visual representation of data that shows the trend or pattern of a variable over time. The peaks and valleys on the line graph indicate the highs and lows of the variable being measured. A histogram, on the other hand, is a bar graph that shows the distribution of data across different categories or intervals. A report is a written or spoken summary of information, while an image is a visual representation of an object or scene.

Question 3

SNMP management systems in different communities can communicate with each other.

Accepted Answer

SNMP management systems in different communities cannot communicate directly with each other because each community is a separate security domain with its own access policies and credentials.

Question 4

A)packet
B)activity
C)data
D)event

Question 5

____ is a TCP/IP service that converts a computer or domain name to an IP address, or that converts an IP address to a computer or domain name.
A)RCP
B)Ipconfig
C)ARP
D)DNS

Accepted Answer

DNS stands for Domain Name System and is a TCP/IP service that converts a computer or domain name to an IP address or IP address to a computer or domain name.

Question 6

A(n)____ time domain reflectometer transmits a light wave instead of an electrical impulse.
A)sensory
B)scanning
C)sonic
D)optical

Accepted Answer

A time domain reflectometer (TDR) is typically used to locate faults or anomalies in a cable or wire. It works by sending an electrical pulse down the cable and measuring the time it takes for the reflection to return. However, an optical TDR works by transmitting a light wave down the cable and measuring the time it takes for the reflection to return. Therefore, the correct choice is D, optical.

Question 7

The volcopy utility can back up to multiple tape drives.

Accepted Answer

The volcopy utility can write to multiple tape drives simultaneously, making it possible to create a backup on multiple tapes at the same time. This can help improve backup speed and resilience, as well as ensuring that there are multiple copies of important data in case one of the tapes fails.

Question 8

____ is used for network error reporting particularly through routers, showing whether or not a packet successfully reaches its destination.
A)UDP
B)ICMP
C)TCP
D)IP

Accepted Answer

ICMP (Internet Control Message Protocol) is a protocol used for error reporting, particularly through routers. It is used to send error messages to network devices to indicate that a particular packet has failed to reach its destination. UDP (User Datagram Protocol), TCP (Transmission Control Protocol), and IP (Internet Protocol) are all network protocols, but they do not specifically handle error reporting like ICMP does.

Question 9

The default view of System Monitor is in the histogram mode.

Accepted Answer

The default view of System Monitor is typically in the process table mode, not histogram mode.

Question 10

The ping command-line utility is an example of a network program that uses the OSI ____ layer.
A)Session
B)Data Link
C)Application
D)Presentation

Accepted Answer

The ping command-line utility uses the Internet Control Message Protocol (ICMP), which operates at the Network layer of the OSI model. However, the utility itself is considered an application that interacts with the network, so it is associated with the Application layer.

Question 11

Windows XP, Windows Server 2003, and UNIX/Linux systems all support the use of the traceroute command-line utility to trace a network connection.

Accepted Answer

Windows XP, Windows Server 2003, and UNIX/Linux systems all support the use of the traceroute command-line utility.

Question 12

In Windows XP or Windows Server 2003, type "____" (don't include the quotation marks)at the nslookup command-line prompt and press Enter to view the commands you can use to query the contents of a DNS server.
A)(?)
B)(!)
C)(&)
D)(*)

Accepted Answer

In both Windows XP and Windows Server 2003, typing "?" at the nslookup command-line prompt will display the available commands for querying a DNS server.

Question 13

A multimeter combines the functions of a voltmeter and an ohm meter.

Accepted Answer

A multimeter can measure voltage (like a voltmeter) and resistance (like an ohmmeter), in addition to other functions such as measuring current and continuity.

Question 14

The SNMP management system (a computer running management software)sends and requests information from an SNMP ____.
A)agent
B)monitor
C)filter
D)protocol

Accepted Answer

An SNMP management system communicates with SNMP agents, which are software modules residing on network devices that provide information to the management system.

Question 15

A(n)____ circuit is one where the connection is severed, such as a cable that is inadvertently cut in two.
A)open
B)closed
C)short
D)long

Accepted Answer

An open circuit is one where the connection is broken, indicating a break or disconnection in the circuit.

Question 16

Which of the following commands is used in the Windows version of the traceroute utility?
A)ping
B)netstat
C)tracert
D)tar

Accepted Answer

The Windows version of the Traceroute utility uses the 'tracert' command to trace the route between two points on a network. 'Ping' is used to check connectivity between two devices, 'netstat' displays active network connections and their status, and 'tar' is a command used in Unix/Linux systems to create compressed archives.

Question 17

With respect to System Monitor, a(n)____ exists when there are different elements to monitor, such as individual processes when you use the Process object.
A)entity
B)thread
C)instance
D)module

Accepted Answer

An instance in System Monitor refers to a specific occurrence of an object, such as an individual process when using the Process object.

Question 18

A server administrator might regularly use ____ with the -s option to monitor a server during busy and light traffic times to get an idea of the typical number of packets sent at those times.
A)netstat
B)ping
C)traceroute
D)dump

Accepted Answer

The netstat command with the -s option displays statistics about network traffic on a server, including the number of packets sent and received. By monitoring these statistics during busy and light traffic times, a server administrator can get an idea of typical network usage patterns. The ping command sends packets to a specific network host to test connectivity, the traceroute command displays the path that network packets take from one host to another, and the dump command captures and displays network traffic. While these commands may be useful for other purposes, they are not as relevant for monitoring network traffic patterns.

Question 19

A cable ____ tester enables you to check for opens or breaks in a cable by determining if the signal sent from one end reaches the other end of the cable.
A)signal
B)transmission
C)continuity
D)integrity

Accepted Answer

The term "continuity" refers to the ability of a cable to maintain an uninterrupted electrical path from one end to the other. A cable continuity tester is designed specifically to check for breaks or openings in the cable by sending a signal from one end and checking if it reaches the other end.

Question 20

____ refers to a property of an Ethernet frame that includes a 2-byte code for the protocol type and is used in Ethernet communications by some vendors, but is not a part of the Ethernet standard.
A)PRE
B)ETYPE
C)SOF
D)DA

Accepted Answer

ETYPE (Ethernet Type) refers to a property of an Ethernet frame that includes a 2-byte code for the protocol type and is used in Ethernet communications by some vendors, but is not a part of the Ethernet standard. PRE (Preamble), SOF (Start of Frame), and DA (Destination Address) are all parts of the Ethernet standard.
