ch 9 Flashcards
SMCS School has hired you to set up an Internet connection within the school premises. The Internet connection will be utilized by both the junior and senior sections of the school situated in two different buildings on the same campus. Which of the following types of network will you install in this scenario?
Campus Area Network (CAN)
As a network administrator, a client has approached you to set up the network for MKV, a software company. The company requires sufficient amounts of data for both uploading and downloading purposes; however, it prefers a connection that has better download speed. Which of the following DSL varieties do you think is best suited for such a requirement?
VDSL (Very high rate DSL or Variable DSL)
is a type of DSL. It is faster than ADSL and also asymmetric. Has faster download speeds than upload speeds. EX: for companies located close to a telephone company CO (Central Office) (in the middle of a metropolitan area).
You are employed as a network engineer. While setting up a client’s connection, the client requests you to display trunks configured on a switch. Which of the following commands will you use in this scenario?
sh int tr
You are working as a network engineer at Krofter Securities. The organization uses Cisco’s Linux OS in all of its workstations. The network administrator has asked you to use the route utility to delete some static routes used by the router. Which of the following commands will you use in this scenario?
route
Which of the following commands can be used to change a device’s name?
hostname
Which of the following traverses a significant distance and usually supports very high data throughput?
WAN
Browski is a company that deals with SD-WAN (software-defined wide area network) units. The management of Browski wants to present an audio-video presentation at one of the network exhibitions to demonstrate its new product. As a network administrator working there, you have been asked to go through a few pointers in the presentation to verify the accuracy of the content. Analyze if any of these aspects do not apply to SD-WAN.
SD-WAN can be more expensive than leased lines.
As a network analyst, you have to separate the digital communication of data in a GSM network. Which of the following will you use in this scenario?
TDMA (Time Division Multiple Access)
is a method of multiplexing in which signals from several sources on a channel are separated by timeslots.
Crom Breweries is an old client of HW Internet Solutions. Crom’s IT department calls HW Solutions to inform that the interface is down. HW Solutions sends a network analyst to check the situation. The network analyst assumes that an employee must have shut down the interface. He applies the show interface command to get an overview of all the devices interfaces. Analyze which of the following will help the network analyst to know whether the interface was shut down.
Link State
Which form of communication is well suited to users who receive more information from the network than they send to it?
ADSL (Asymmetric DSL)
is the most common form of DSL. Faster download speeds than upload speeds. EX: Surfing the Web, watching a movie.
XYZ Ltd. is a company that has 12 regional offices around the world. All the major operations of the company are carried out from the headquarters based in New York. XYZ Ltd. has approached you, a network facilitator, to install a WAN service that can manage network configurations at multiple locations throughout the world. Which of the following WAN services would you advise to XYZ Ltd. in this scenario?
SD-WAN (Software-Defined Wide Area Network)
abstracted, centralized control of networking devices that manage network functions across a diverse infrastructure.
*Pic: SD-WAN supports many underlying WAN connectivity technologies.
Beevan works as a network analyzer for an ISP. The network manager has asked him to use a protocol for the routers that can scan beyond the home territory and can instruct a group of routers to prefer one route over other available routes. Analyze which of the following should be used in this scenario.
BGP (Border Gateway Protocol)
dubbed the “Protocol of the Internet,” this path-vector routing protocol is the only current EGP (Exterior Gateway Protocol) and is capable of considering many factors in its routing metrics.
Bradley has been running a business in his garage for over a period of 10 years. He plans on expanding the business by opening up three new offices in three different cities. Since he has accumulated sufficient profits to move to a larger office space, he plans to upgrade his network connection to one with a dedicated and symmetrical bandwidth. Bradley approaches Mantle Solutions, an ISP. Which of the following options should be offered by the ISP in this term-4scenario?
Leased Lines
dedicated Internet bandwidth provided over fiber-optic connections.
*Pic: Each location needs its own Leased Line
Which of the following devices serves as the endpoint for a dedicated connection between an ISP and a customer?
CSU/DSU (Channel Service Unit/Data Service Unit)
You are working as an executive for a cable company. A client raises a request to set up a network that uses fiber-optic cabling to connect your company’s distribution center to distribution hubs and then to optical nodes near its customers. From the following network options, which one would you recommend in the given scenario?
HFC (Hybrid Fiber Coaxial)
either fiber-optic or coaxial cable then connects a node to each customer’s business or residence.
*Pic: HFC Infrastructure
You are employed as a network engineer. While setting up a client’s connection, the client requests you to display the concise network layer information of the device interface that is being installed. Which of the following commands will you use in this scenario?
