   • Frequency mismatch

4. A company’s server-naming convention is overly complicated.

   • TXT
   • A
   • SRV
   • CNAME

5. A network technician is working on a way to set up a new branch office securely.

   • Client-to-site VPN
   • DMVPN
   • Site-to-site VPN
   • MPLS VPN

6. A network administrator has noticed many systems on the network have traffic that is anomalous and may be part of a botnet.

Which of the following should the administrator deploy?

   • 802.1X
   • Captive portal
   • Port security
   • NAC

7. A network technician is reviewing the following output from a router:

   

   Which of the following is this an example of?

   • A vulnerability scan
   • A port scan
   • A traffic log
   • A packet capture

8. A user claims to have no Internet access but can access local resources. A technician determines the issue is with a configuration because a ping to a working public website shows a response that starts with:

   Ping request could not find host

   Which of the following is the MOST likely misconfiguration?

   • Incorrect netmask
   • DNS
   • DHCP
   • SSL certificate

9. A network engineer wants to implement a technology that allows for an all-in-one approach to incoming and outgoing traffic from the Internet. This device should be able to filter content and scan for malicious information in each packet. Which of the following types of devices would be necessary?

   • UTM appliance
   • IDS appliance
   • Proxy server
   • RADIUS server

10. Which of the following technologies allows network traffic to come into the network on a certain port and go to a destination server with a different port?

    • Spanning port
    • Port forwarding
    • Port mirroring
    • Port tagging

11. An attacker has inserted a hub into a trunk link on the local network in an attempt to access the management subnet to attack the networking devices. Which of the following attacks can be used on a trunk link to provide access to the management subnet?

    • Brute force
    • VLAN hopping
    • Evil twin
    • DNS poisoning

12. A developer has asked a network engineer for a small network segment of five computers connected via a Layer 1 device, configured in a star topology, and segregated from the corporate network. Which of the following would BEST fulfill the developer’s request?

    • Connect the five PCs to a hub that is not connected to the corporate network.
    • Connect the five PCs to a switching router and assign the PCs to a separate VLAN.
    • Connect the five PCs to a hardware firewall that is connected to the router.
    • Connect the five PCs to a switch and configure the ports with implicit deny ACLs for outbound traffic.

13. A network engineer wants to change how employees authenticate to the wireless network. Rather than providing a pre-shared key, the engineer wants employees to be able to authenticate with the same unique company user ID and password they use for accessing other services, such as email and document sharing. The engineer also wants to receive daily reports of login attempts on the wireless network. Which of the following should be installed to achieve this goal?

    • LDAP server
    • UTM appliance
    • Multilayer switch
    • AAA/RADIUS server

14. Which of the following provides information about how often some devices fail so the IT department can take proactive measures?

    • MTBF
    • MTTR
    • SLA
    • UPS

15. Which of the following additional capabilities does a next generation firewall provide beyond a standard network firewall? (Choose two.)

    • Application control
    • User identification
    • Network address translation
    • Virtual private networking
    • High availability
    • Access control rules

16. First thing on Monday morning, after a maintenance weekend, the help desk receives many calls that no one can access the Internet. Which of the following types of documentation should the on-call network administrator consult FIRST?

    • Firewall configuration documentation
    • Change management documentation
    • Network performance baseline
    • Logical diagram

17. A network team at a large company has received funding for a WiFi refresh. One of the requirements in the RFP is the new WLAN infrastructure must provide APs that support multiple streams of information at the same time. For which of the following WiFi features is the network team looking?

    • MU-MIMO
    • MIMO
    • Channel bonding
    • TDM
    • Automatic channel selection

18. Multiple users are experiencing slow performance when downloading large files from a specific site. Which of the following should the technician do to check the connection to the external site?

    • Check the latency by running a continuous ping to the site.
    • Perform the ipconfig/flushdns command on the affected users’ PCs.
    • Run a speedtest from a user’s PC to a site on the Internet.
    • Verify if there is MTU mismatch in the path to the site.

19. A user has reported an issue with wireless VoIP phones dropping calls during business hours. When working late or in the evenings, the user does not experience call drops. When the network technician investigates the issue, all WAPs have balanced the number of connections evenly and are not dropping off the network. The network technician connects to the wireless network in the user’s office and starts a continuous ping to an external server. The results show a drastic and varied response time for each packet. Which of the following is the MOST likely cause of the dropped calls?
