Q

Match these network protocols to their description. Not all protocols will be used.
(SMB , SSH , SSH , LDAP , IMAP , Telnet , SMTP , HTTPS , SNMP , RDP , DHCP , DNS , FTP)

  1. Control the desktop of a remote computer
  2. Send email messages from a mobile device
  3. Gather statistics from network devices
  4. Automatically assign IP addresses
  5. Resolve an IP address from an FQDN
  6. Print from Windows to a network printer
  7. Encrypt a terminal connection
A
  1. RDP (Remote desktop Protocol) is used for viewing and controlling the desktop of a remote device. RDP is commonly associated with controlling a device running a Microsoft operating system.
  2. SMTP (Simple Mail Transfer Protocol) is used to send messages from adevice or to transfer email messages between email servers over tcp/25
  3. SNMP (Simple Network Management Protocol) is used to monitor and configure network devices over udp/161. Devices can send alerts (called “traps”) to an SNMP console over udp/162
  4. DHCP (Dynamic Host Configuration Protocol) is the primary protocol commonly used to automate the configuration of IP addresses, subnet masks, and other networking options. DHCP uses both udp/67 and udp/68 for these auto-configuration tasks.
  5. DNS (Domain Name System) services are most commonly used to convert between an FQDN (Fully Qualified Domain Name) and an IP address. DNS allows us to refer to devices by name instead of using an IPv4 or IPv6 address each time
  6. SMB (Server Message Block), is commonly used on Windows systems to share files and printers over tcp/445
  7. SSH (Secure Shell) is used to communicate to a terminal screen over an encrypted channel using tcp/22

Q

Choose the correct network tool. Not all tools will be used
(Crimper , Cable stripper , Toner Probe , Punchdown Tool , Cable Tester , Loopback Plug , Network Tap)

  1. Locate one cable inside of a bundle of fifty cables
  2. Verify the connected pins on both sides of an Ethernet cable
  3. Fasten an RJ45 connector to a Category 6 cable
  4. Capture a network conversation to measure bandwidth usage
A
  1. Toner Probe - The toner probe is actually two separate components; the tone generator and the inductive probe. The tone generator is attached to one end of the cable, and the inductive probe is used to locate the other end of the cable. The tone can be located relatively quickly, even in a large bundle of cables
  2. Cable Tester - A cable tester can provide a continuity test through a network cable to build a simple wire map of the pins
  3. Crimper - A crimper is used to physically attach the connector to the end of a network cable. Crimpers are available for RJ45, RJ11, coax, and other types of connectors
  4. Network Tap - A network tap is used to intercept network traffic and send a copy of the traffic to a packet capture or similar device

Q

Match the printer type to the technology:
(Laser , Inkjet , Thermal , Impact , 3D)

  1. Heating element
  2. Ribbon
  3. Ink cartridge
  4. Fuser
  5. Plastic filament
A
  1. Thermal - A thermal printer uses a heating element to change the color of specially treated paper. Thermal printers print very quietly, but the paper is sensitive to light and heat
  2. Impact - An impact printer uses a print head to physically impact the printed page. A ribbon is placed between the print head and the page to create marks on the paper
  3. Inkjet - An inkjet printer places small drops of ink onto a page, and the printer commonly contains cartridges that store the ink
  4. Laser - The fuser assembly of a laser printer uses heat and pressure to melt plastic toner powder and permanently bond the toner to the page
  5. 3D - 3D printers melt plastic filament or harden resin to create objects in three dimensions

Q

The computers in the shipping department are receiving the message “No connectivity” on their computers. The ipconfig output on one of the computers provides this information:

IPv4 Address: 192.168.1.22
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.1.1

From this device, a technician is able to successfully ping 127.0.0.1 and 192.168.1.22. The technician can also ping other devices in the shipping department, but cannot receive a ping response from servers in the data center or from the 192.168.1.1 address.

A network administrator is planning to connect the network of two buildings together with a Category 6A cable. Ten Ethernet cables have been run from a wiring closet, through a conduit, and into a wiring closet on the other side. The network administrator needs to identify the ends of the cables so they can be properly terminated on each side. Which of the following should be used to complete this task? ❍ A. Cable stripper ❍ B. Loopback plug ❍ C. Tone generator ❍ D. Crimper
The Answer: C. Tone generator A tone generator places an analog audio tone onto the wires of a cable, and an inductive probe is used on the other end to precisely identify the cable with the tone. By moving the tone generator to each of the ten cables, the other end of the cable can be easily identified and labeled
53
A server administrator has configured a database server with a RAID 0 array containing four hard drives. An error notification from the RAID controller states that disk 3 has failed. Which of the following would be the BEST way to address this disk failure? ❍ A. Replace the drive and re-mirror the array ❍ B. Replace the drive and resynchronize the array ❍ C. Replace the drive and restore from backup ❍ D. Replace all drives and restore from backup ❍ E. Replace all drives and resynchronize the array
The Answer: C. Replace the drive and restore from backup RAID 0 (Redundant Array of Independent Disks, Level 0) provides an efficient storage method at the expense of redundancy. Data in RAID 0 is striped across multiple drives, and if one drive is lost the data in the array is also lost. To repair a failed RAID 0 array, the bad drive will need to be replaced and all of the data must be restored from a backup

A network engineer is troubleshooting an issue communicating to the Internet over a newly installed DSL connection. A laptop is connected to a DSL router over twisted pair copper. The IP configuration of the laptop is: IP address: 169.254.228.109 Subnet mask: 255.255.0.0 DNS: 9.9.9.9 Which of the following should be the NEXT troubleshooting step? ❍ A. Reset the DSL modem ❍ B. Modify the subnet mask ❍ C. Change the DNS server address ❍ D. Check the status of the DHCP server
The Answer: D. Check the status of the DHCP server A DHCP (Dynamic Host Configuration Protocol) server automatically distributes IP addresses to new devices connecting to a network. If the DHCP server isn't available, a device will commonly auto-configure itself with an APIPA (Automatic Private IP Addressing) address. Addresses between the range of 169.254.1.0 through 169.254.254.255 are assigned to devices using APIPA
59

What type of power supply can operate across countries using different voltages? ❍ A. High-voltage ❍ B. Primary ❍ C. Modular ❍ D. Auto switching
The Answer: D. Auto switching An auto switching power supply can automatically detect and use different input voltages without the need to manually select an input voltage. This is especially useful when using equipment in countries with 120 volts of alternating current, and then move that same equipment to a country using 240 volts of alternating current
63
A user is reporting after starting their desktop, they receive the message “Windows has detected an IP address conflict.” Which of the following would be the BEST way to resolve this issue? ❍ A. Replace the Ethernet patch cable ❍ B. Enable DHCP on the workstation ❍ C. Bounce the switch port ❍ D. Reboot the default gateway
The Answer: B. Enable DHCP on the workstation One of the more useful features of a DHCP (Dynamic Host Configuration Protocol) server is the controlled assignment of IP (Internet Protocol) addresses. If the DHCP server is assigning all IP addresses, then a duplicate is unlikely. If a device is configured for manual addressing, then configuring the device to receive IP addresses via DHCP can avoid possible address duplication
64
Each time a user logs in, they must type their password and a random number from a smartphone app. Which of the following would BEST describe this process? ❍ A. PRL update ❍ B. Bluetooth pairing ❍ C. NFC data transfer ❍ D. Two-factor authentication
