Chapter 20 - Management, Monitoring, and Optimization Flashcards
UTP cables use which type of connector?
A. RJ-11
B. RJ-25
C. RJ-45
D. BNC
- C. UTP cables use an RJ-45 connector. RJ-11 and RJ-25 are often used for terminating telephone lines.
Which type of cable will have the pins in the same order on both connectors?
A. Crossover cable
B. Straight-through cable
C. Console cable
D. Telephone cable
- B. Straight-through cables, known as drop cables or patch cables, will have the pins in the same order on both connectors.
Which pins are switched in a crossover cable?
A. 1 and 2, 3 and 4
B. 1 and 3, 2 and 6
C. 2 and 4, 5 and 7
D. 1 and 4, 5 and 8
- B. On a crossover cable, one connector has flipped the wires. Specifically, pins 1 and 3 get switched, and pins 2 and 6 get switched.
UTP cable has specific colors for the wire associated with each pin. Based on the TIA/EIA 568B wiring standard, what is the correct color order, starting with pin 1?
A. White/Orange, Orange, Blue, White/Green, White/Blue, Green, White/Brown, Brown
B. Orange, White/Orange, White/Green, Blue, White/Blue, White/Brown, Brown, Green
C. White/Orange, Orange, White/Green, Blue, White/Blue, Green, White/Brown, Brown
D. White/Green, Green, White/Orange, Blue, White/Blue, Orange, White/Brown, Brown
- C. If you are going to make your own UTP cables (drop/patch cables) to customize length, you need to make sure that the right wires get to the right pins.
What is the technical term for what happens when two objects of dissimilar charge come in contact?
A. RFI
B. EMI
C. ESD
D. Crosstalk
- C. Electrostatic discharge (ESD) is the technical term for what happens when two objects of dissimilar charge come in contact.
Which of the following govern how the network is configured and operated as well as how people are expected to behave on the network?
A. Baselines
B. Laws
C. Policies
D. Procedures
- C. Policies govern how the network is configured and operated as well as how people are expected to behave on the network, such as how users are able to access resources and which types of employees get network access.
You have upgraded the firmware on your switches and access points. What documentation do you need to update?
A. Baselines and configuration documentation
B. Physical network diagram
C. Logical network diagram
D. Wiring schematics
- A. A physical network diagram contains all the physical devices and connectivity paths on your network and should accurately picture how your network physically fits together in detail. This document will also have the firmware revision on all the switches and access points in your network.
In an ICS, which of the following uses coded signals over communication channels to acquire information about the status of the remote equipment?
A. ICS server
B. Telemetry system
C. Human interface
D. PLC
- A. An ICS server, also called a data acquisition server, uses coded signals over communication channels to acquire information about the status of the remote equipment for display or for recording functions.
Load testing, connectivity testing, and throughput testing are all examples of what?
A. Load balancing
B. Network monitoring
C. Packet sniffing
D. Traffic shaping
- B. Network monitoring can have several names, including load testing, connectivity testing, and throughput testing. You will also hear network monitors referred to as protocol analyzers.
What can provide different priority levels to different applications, data flows, or users to help guarantee performance levels?
A. 1 Gbps connection
B. Bandwidth
C. Uptime
D. Quality of Service
- D. QoS provides different priority levels to different applications, data flows, or users so that they can be guaranteed a certain performance level.
Which of the following identifies steps to recover from adverse effects caused by a change?
A. Rollback process
B. Approvable process
C. Notification process
D. Impact assessment
- A. Those making the changes should be completely briefed in rollback procedures, and they should exhibit a clear understanding of them prior to implementing the changes.
After a change has been made, which of the following is not a document that needs to be updated?
A. Network configurations
B. Additions to the network
C. Physical location changes
D. All of the above
- D. The job isn’t complete until the paperwork is complete. In this case, network configurations, additions to the network, and physical location changes should be updated to reflect the changed state of the network.
Which of the following provides increased availability to firewalls and gateways?
A. DHCP
B. CARP
C. SaaS
D. NaaS
- B. Common Address Redundancy Protocol (CARP) can be used to increase availability of gateways and firewalls.
You have added a new cable segment to your network. You need to make sure you document this for troubleshooting purposes. What should you update?
A. The disaster recovery plan
B. The wiring schematics
C. The router connections document
D. The baseline document
- B. If you add a new cable segment to the network, you need to update the wiring schematics document.
What is the basic purpose of QoS? (Choose two.)
A. Block access to certain websites
B. Make your entire network run faster
C. Provide priority to one or more types of traffic over others
D. Block access to web resources for just certain users or groups
E. Prioritize delay-sensitive traffic
- C, E. Quality of service (QoS) is basically the ability to provide different priority to one or more types of traffic over other levels for different applications, data flows, or users so that they can be guaranteed a certain performance level.
