The following image depicts what type of Storage?
What is "DAS"
Direct Attached Storage

The following is example of what type of cable?
What is "Fiber Optic Cable, LC style"
Scott's Useless Facts: Did you know that LC came from the company Lucent Technology which first developed this style of connector. They have also been dubbed "Little Connector and Local Connector"
SC cable is the bigger style cable and SC was dubbed "Stick & Click". SC to LC cable would have SC on one end and LC on the other
10G LC/LC Optical Fiber: Optical cables use light to transfer data. Called Fiber, Optical
Utilize a device called a transceiver that connects at each end of the cable to plug into a 10GbE Optical port. Transceivers can also be called Optics or SFP’s by customers.
Pro’s
1.Fiber can cover greater distances without a repeater
2.Impervious to EMI
Con’s
1.Expensive. Requires additional connectors.
2.Damaged cable cannot be repaired without specialized equipment.
3.Fragile. Needs additional cable management to implement properly.
Initial setup headaches. Need to “roll” fiber.

What does NAT stand for?
What is "Network Address Translation"
100
What type of solution is the following hardware?
HCI "Hyper Converged Infrastructure"
VxRail HCI System Software, a suite of integrated software elements that sit between infrastructure delivers a seamless, automated, operational experience. Intelligent lifecycle management (LCM) automates non-disruptive upgrades, patches, node additions and retirement while keeping VxRail clusters in continuously validated state.
200
Name two block protocols
What is
1. iSCSI
2. Fibre Channel
200
A customer has Fibre Channel, iSCSI, and some SMB in their datacenters. Please identify which solution best fits the customers needs.
What is "PowerStore T"
SC does not support file workloads
200
The following picture represents what type of cabling?
What is "Ethernet"
•10GBASE-T Ethernet cables: These cables are made up of twisted pair copper cables. They can also be called twisted pair cables, copper cables, CAT5 cables, Ethernet cables. CAT 5e/6/6a/7/8.
•Utilize 1GbE and 10GbE speeds and can auto negotiate down 1 tier. 25GbE and 40GbE are available with high end cables.
Pro’s
1.Affordable. Made up of twisted telephone wire, doesn’t need additional connectors.
2.Durable
Con’s
1.Susceptible to Electromagnetic Interference (EMI)
Transmission distance limitation (100M)
200
What is a device that connects servers together called?
What is "Switch"
200
What type of workloads best fits this solution?
File
300
Name two file protocols
What is "CIFS, NFS"
300
Please identify this piece of hardware
What is "SFP+, SFP, GBIC, Transceiver"

SAN - What type of adapter is this?
What is "Host Bus Adapter (HBA)"

What is the purpose of the SSD(s) in a Hybrid VxRail Cluster?
What is "Caching Drives"
Caching drives; all reads/writes are processed through the SSDs for faster performance, and data is ultimately stored on the underlying spinning disk

What is the largest and best known TCP/IP network.
What is the "Internet"
400
What speeds are available for standard ethernet? List 3
What are "1, 10, 25, 100 GB"
400
Please identify which speed is not associated with Fibre Channel.
2Gb, 4Gb, 16GB, 32Gb, 100Gb, 128Gb
What is "100Gb"
400
Please identify the following cable
Twinax
•10GbE Copper Twinax cable:
•Very similar to a coax cable used in homes for cable. There are two copper wires that sit side by side and share their protective jacketing.
•Utilize SFP+ transceivers to terminate at ends.
•
•Pro’s
1.Affordable & FAST. Can use SFP+ ports, same as fiber connections (no additional switches needed).
2.Easy to install initially.
•Con’s
1.Transmission distance 10M
Large and bulky. Re-cabling nightmare, airflow issues

What is DNS and its purpose?
What is "Domain Name System"
The main function of DNS is to translate domain names into IP Addresses, which computers can understand. It also provides a list of mail servers which accept Emails for each domain name
Scott's Tip: Think of DNS like the old school phone books (If any of you remember these). Open the phone book and I need to find out what street (Ip Address) that Grace (Domain name) lives at.

Customer has a physical server that has the ip address 10.1.1.100 and he needs it to talk to his brand new PowerStore 9000T which resides on 20.1.1.100. What type of device does the customer need to have to make this happen?
What is a "Router"

Connectrix Switches are rebranded switches from what two companies?
What is "Cisco & Brocade"
500
This protocol is used to automatically discover, manage, and configure iSCSI devices on a TCP/IP network.
What is "iSNS"
Internet Storage Name Service

The following picture represents what?
What is the "OSI model"
For IT professionals, the seven layers refer to the Open Systems Interconnection (OSI) model, a conceptual framework that describes the functions of a networking or telecommunication system.
