6. A building is equipped with light sensors that turn off the fluorescent lights when natural light is above a certain brightness.

The west side of the building experiences connectivity issues in the morning hours and the east side near the end of the day. At night the connectivity issues affect the entire building. Which of the following could be the cause of the connectivity issues?

   • Network wiring is run perpendicular to electrical conduit
   • Temperature changes are causing attenuation in copper cabling

7. A network technician configures a firewall’s ACL to allow outgoing traffic for several popular services such as email and web browsing. However, after the firewall’s deployment, users are still unable to retrieve their emails. Which of the following would BEST resolve this issue?

   • Allow the firewall to accept inbound traffic to ports 25, 67, 179, and 3389
   • Allow the firewall to accept inbound traffic to ports 80, 110, 143, and 443
   • Set the firewall to operate in transparent mode
   • Allow the firewall to accept inbound traffic to ports 21, 53, 69, and 123

8. A network security technician observes multiple attempts to scan network hosts and devices. All the attempts originate from a single host on the network. Which of the following threats is MOST likely involved?

   • Smurf attack
   • Rogue AP
   • Compromised system
   • Unintentional DoS

9. Which of the following would be the MOST efficient subnet mask for a point-to-point link?

   • /28
   • /29
   • /31
   • /32

10. An office user cannot access local network drives but has full access to the Internet. A technician troubleshoots the issue and observes the following output of the ipconfig command:

    

    Which of the following would MOST likely allow the network drives to be accessed?

    • Update the WLAN adapter driver
    • Disable the WLAN adapter
    • Check the wireless DHCP configuration
    • Disable the LAN adapter

11. Ann, a network technician, has just installed a fiber switch in a datacenter. To run the fiber cabling, Ann plans the cable route over the top of the rack using the cable trays, down to the switch, coiling up any excess cable. As Ann configures the switch, she notices several messages in the logging buffer stating the receive signal of the SFP is too weak. Which of the following is MOST likely the cause of the errors in the logging buffer?

    • Bend radius exceeded
    • Fiber cable mismatch
    • Fiber type mismatch
    • Bad fiber switch

12. Which of the following wireless connection types utilize MIMO on non-overlapping channels? (Choose two.)

    • 802.11a
    • 802.11ac
    • 802.11b
    • 802.11g
    • 802.11n

13. A network technician is creating a new subnet for 488 host machines. The technician is told to use a class B address scheme when making the subnet and is instructed to leave as much room as possible for additional subnets of the same size. Which of the following subnets would fulfill these requirements?

    • 10.5.4.0/22
    • 10.233.2.0/23
    • 172.16.0.0/22
    • 172.18.0.0/23
    • 192.168.25.0/24

14. A network engineer is designing a new IDF in an old building. The engineer determines the equipment will fit in a two-post rack, and there is power available for this equipment. Which of the following would be the FIRST issue to remediate?

    • Air flow and cooling
    • UPS capability
    • Circuit labeling
    • Power redundancy

    • CNAME
    • AAAA
    • PTR

16. In which of the following ways does a DDoS attack differ from a spoofing attack?

    • DDoS attacks target multiple networks
    • Spoofing attacks originate from a single host
    • DDoS attacks are launched from multiple hosts
    • Spoofing attacks require physical presence

17. A user checks an IP address using an external website. The address is different than the one the user sees when opening a command prompt and typing in ipconfig/all. The user does not understand why the two tools show different IP addresses. This is BEST explained by the interworking of:

    • network devices
    • packet flow
    • public/private networks
