NS – Modules 20 – 22

1. Users on a LAN segment are reporting a loss of connectivity to network services. The client PCs have been assigned with 169.254.X.X IP addresses. Which of the following IP address schemas is being utilized?

4. A technician has installed an older IP camera as a temporary replacement for a recently failed newer one. The technician notices that when the camera’s video stream is off, the ping roundtrip time between the camera and the network DVR is consistently less than 1ms without dropped packets. When the camera video stream is turned on, the ping roundtrip time increases dramatically, and network communication is slow and inconsistent. Which of the following is MOST likely the issue in this scenario?

   • VLAN mismatch
   • Duplex mismatch
   • Cat 6 RX/TX reversed
   • Damaged cable

5. Wireless users have been experiencing connectivity problems. Investigation shows neighboring wireless appliances, which are not connected to the network, have been on the same 5GHz frequency to communicate. Which of the following wireless performance problem concepts defines this issue?

   • Signal-to-noise ratio
   • Absorption

6. Which of the following BEST explains the purpose of signature management as a mitigation technique?

7. A network technician installs a web server on the firewall. Which of the following methods should the technician implement to allow access to outside users without giving access to the inside network?

   • VLAN
   • DMZ
   • SNMP
   • NTP

8. A Chief Information Officer (CIO) tasks the network engineer with protecting the network from outside attacks. Placing which of the following devices on the network perimeter would provide the MOST security for the system?

   • Firewall
   • NGFW
   • Content filter
   • IDS/IPS

9. Management has requested that a wireless solution be installed at a new office. Which of the following is the FIRST thing the network technician should do?

   • Order equipment
   • Create network diagrams
   • Perform a site survey
   • Create an SSID.

10. A technician has deployed an additional DHCP server for redundancy. Clients in certain subnets are not receiving DHCP leases from the new DHCP server. Which of the following is the MOST likely cause?

    • The new DHCP server’s IP address was not added to the router’s IP helper list.
    • The new DHCP server is not receiving the requests from the clients.
    • The ARP cache of the new DHCP server needs to be updated.
    • The ARP table on the router needs to be cleared.

11. Greater bandwidth and availability are required between two switches. Each switch has multiple 100Mb Ethernet ports available. Which of the following should a technician implement to help achieve these requirements?

    • Spanning tree
    • Clustering
    • Power management
    • Port aggregation

12. A technician is configuring a new server with an IP address of 10.35.113.47 on the 10.35.112.0 subnet to allow for the maximum number of hosts. When configuring network settings, which of the following is the correct subnet mask?

    • 10.35.112.0/30
    • 10.35.112.0/24
    • 255.255.240.0
    • 255.255.248.0
    • 255.255.255.0

13. Ann, a customer, recently upgraded her SOHO Internet to gigabit fiber from cable. She was previously getting speeds around 75Mbps down and 25Mbps up. After the upgrade, Ann runs a speed test on her desktop and gets results of 1000Mbps down and 100Mbps up. A technician connects directly to the router and sees the correct 1000Mbps speeds. Which of the following is MOST likely the cause? (Choose two.)

    • All ports should be configured for full duplex.
    • There is a 10/100 switch on the network.
    • The connections are using Cat 5 cable.
    • The connections are using Cat 6 cable.
    • There is a transceiver mismatch at the fiber termination point.
    • Signal attenuation on the new fiber has reached the upper limits.

14. A user reports intermittent performance issues on a segment of the network. According to the troubleshooting methodology, which of the following steps should the technician do NEXT after collecting initial information from the customer?

    • Document findings, actions, and outcomes.
    • Establish a theory of probable cause.
    • Establish a plan of action to resolve the problem.
    • Duplicate the problem, if possible.

15. Which of the following protocols is associated with a three-way handshake?

    • UDP
    • ICMP
    • GRE
    • TCP

16. Which of the following would a company place at the edge of its network if it wants to view and control which Internet applications are being used?

    • VPN concentrator
    • NGFW
    • IDS/IPS
    • Proxy server

    • Cat 5e
    • Cat 6a
    • Multimode
    • Coaxial

18. A network engineer at a multinational company is asked to purchase mobile phones for senior executives who often travel internationally. The executives want their phones to work with wireless carriers in multiple countries when they travel. Which of the following cellular standards should these new phones support?

    • GSM
    • TDM
    • CDMA
    • PSTN

19. DRAG DROP

    You are tasked with creating a network that will accomplish the following requirements.

    Requirements:

    The remote Sales Team must be able to connect to the corporate network.
    Each department must have ONLY two PCs and a server.
    Each department must be segmented from each other.
    The following VLANs have been designed:
    – VLAN 2 – Finance
