ISM 3004 EXAM 3 QUESTIONS WITH COMPLETE
SOLUTIONS
What is Cybersquatting? -- Answer ✔✔ When someone registers a name and sits on it
then will sell it to someone who wants it
What is meant by the term "last mile"? Why should an organization care about the last
mile? -- Answer ✔✔ The last part of the high performance internet to the customer.
The weakest link in the chain is the one that determines the strength of the chain.
What is DAS? What problem does it solve? -- Answer ✔✔ Distributed antenna system.
It solves the problem of not having service in certain parts of buildings it boosts service
in specific areas
What is "latency"? -- Answer ✔✔ ½ second round trip, even at the speed of light
Net Neutrality - what's the basic issue? Who is on each side of the issue and why? --
Answer ✔✔ When network providers low down internet based off of favoring
customers or certain types of data. Internet service companies and consumers are
against the providers of the network
,Geosynchronous Orbit -- Answer ✔✔ when it stays stationary above earth, limited
parking spots, expensive, a lot of customers per satellite which leads to latency.
Briefly describe the Starlink service and the "constellation" they are building -- Answer
✔✔ Better than nothing beta program. Twice as fast by the end of 2021, unlimited data,
fixed location
Not a single satellite there is a constellation of multiple that can be used. Roughly 1200
satellites, 60 more each launch. Goal: 42,000 satellites at 340 miles into orbit
What customers are most likely to benefit from a service like Starlink? -- Answer ✔✔
Serving people in areas with no high speed internet service.
What is WAN? Briefly, how is it constructed? -- Answer ✔✔ Wide area network.
Dedicated private data servers who connect to each office
How well does WAN address remote office needs? What about mobile users? --
Answer ✔✔ It does not allow mobile users but works for remote offices
What is the problem with using the public Internet to connect remote offices and
mobile users to an organization's private resources? -- Answer ✔✔ too risky and lost
functionality
Virtual Private Network (VPN) -- Answer ✔✔ All data is safe and encrypted, but uses
public internet
how do remote offices connect to VPN -- Answer ✔✔ Uses a corporate router
attached to an internet service provider
, How do mobile users connect to a VPN? -- Answer ✔✔ Install vpn software onto the
mobile user and that will encrypt the data before it is sent to the other user
For remote office and mobile user VPNs, identify where on the network diagram the
data is encrypted -- Answer ✔✔ Mobile: it is encrypted on the mobile device
Remote: encrypted at the corporate router
What is an SSD? How does it address these problems? -- Answer ✔✔ Solid state drives
Faster than magnetic hard drives, lower power consumption, RAID (spreads workload),
prices dropping
What is Automated Data Tiering? How does it address these problems? -- Answer ✔✔
Match storage performance to access frequency
Current working data-> top tier-> SSDs
Recently used-> mid-tier-> hard drives
Historical->bottom tier-> tape
What is DeDupe? How does it address these problems? -- Answer ✔✔ Automatically
discovers duplication. Much duplication in unstructured data. Single storage for any data.
Multiple instances are pointers to single copy
What are "data silos"? How do they come into being? Why is this a problem? -- Answer
✔✔ The data collections being completely separated with no sharing possible. Obsolete
legacy systems, incompatible systems, missed opportunities
