4. Which of the following BEST describes the differences between VLAN hopping and session hijacking?

   • VLAN hopping involves the unauthorized transition from one VLAN to another to gain additional access. Session hijacking involves overriding a user’s web connection to execute commands
   • VLAN hopping is a brute force attack executed to gain additional access. Session hijacking involves physically disrupting a network connection
   • VLAN hopping involves overriding a user network connection to execute malicious commands. Session hijacking involves compromising a host to elevate privileges
   • VLAN hopping is the act of exploiting poor VLAN tagging. Session hijacking is a web-based attack aimed at privilege escalation

5. An analyst is developing a proof of concept of a wireless-based attack as part of a penetration test against an organization’s network. As part of the attack, the analyst launches a fake access point matching the SSID of the organization’s guest access network. When a user connects to the fake access point, the analyst allows the traffic to flow through the access point to the legitimate site while the data traversing the network is logged for latest analysis and exploitation. Which of the following attacks has the analyst successfully performed in this scenario?

   • Bluesnarfing
   • Session hijacking
   • MAC spoofing
   • VLAN hopping
   • Man-in-the-middle

6. A network administrator receives a call from the sales department requesting ports 20 and 21 be opened on the company’s firewall to allow customers to retrieve a large file. Which of the following should the administrator perform BEFORE making the needed changes? (Choose two.)

   • Document the reason for the request
   • Scan the file for malware to protect the sales department’s computers
   • Follow the company’s approval process for the implementation
   • Install a TFTP server for the customers to use for the transfer
   • Create a honeypot to store the file on for the customers to use
   • Write the SLA for the sales department authorizing the change

7. A user reports that a laptop cannot connect to the Internet despite the fact the wireless Internet was functioning on it yesterday. The user did not modify the laptop in any way, and the wireless Internet is functional on other users’ laptops. Which of the following issues should be reviewed to help the user to connect to the wireless network?

   • Wireless switch toggled off
   • WAP settings
   • WLAN IP address out of scope
   • Wireless controller misconfiguration

8. A network administrator wants to increase the confidentiality of the system by hardening the authentication process. Currently, the users log in using usernames and passwords to access the system. Which of the following will increase the authentication factor to three?

   • Adding a fingerprint reader to each workstation and providing a RSA authentication token
   • Adding a fingerprint reader and retina scanner
   • Using a smart card and RSA token
   • Enforcing a stronger password policy and using a hand geometry scan

9. A network technician is building a network for a small office. The office currently has cable TV and now requires access to the Internet without adding any cabling other than what is already in place. Which of the following solutions should the technician install to meet these requirements?

   • DOCSIS modem
   • Wireless router
   • DSL modem
   • Access point

10. A network engineer arrives at work and discovers that many users are having problems when attempting to connect to the company network shared drives. The network operations center (NOC) technician just completed server upgrades the night before. To which of the following documents should the NOC technician refer to determine what potentially caused the connectivity problem?

    • Network maps
    • Cable management
    • Release notes
    • Change management

11. Which of the following VPN protocols establishes a secure session that can be initiated using a browser?

    • IPSec
    • SSL VPN
    • PTP
    • PPTP

12. A technician is setting up a public guest network for visitors to access the Internet that must be separate from the corporate network. Which of the following are the BEST steps for the technician to take with minimum overhead configuration? (Choose two.)

    • Enable SSID broadcasting to identify the guest network
    • Configure visitor devices to use static IP addresses
    • Enable two-factor authentication on visitor devices
    • Configure the access point to use WPA2-AES encryption
    • Ensure the access point is not running in mixed mode

13. When choosing a type of storage that integrates with the existing network infrastructure, the storage must be easily configurable to share files and can communicate with all existing clients over TCP/IP. Which of the following is the BEST technology for the network administrator to implement?

    • iSCSI
    • Fibre Channel
    • NAS
    • DAS

14. A network technician is installing a new network switch is looking for an appropriate fiber optic patch cable. The fiber optic patch panel uses a twist-style connector. The switch uses a SFP module. Which of the following connector types should the fiber patch cable have?

    • LC
    • ST
    • SC
    • MTRJ
    • MTP

15. Which of the following WAN technologies utilizes the concept of virtual circuits and point-multipoint connections?

    • ISDN
    • MPLS
    • PRI
    • Broadband cable
    • Frame relay

16. A network administrator wishes to ensure there are no unnecessary open communication paths into a server. Using a port scanner, the administrator finds that ports are reported as closed. Which of the following BEST explains this response?

    • The ports belong to an active system and are denying requests
    • The ports are associated with deprecated services
    • The ports do not belong to a live system
    • The ports replied with a SYN/ACK response

17. Users are reporting issues with slow connection speeds and a loss of connectivity on the newly installed wireless network. The issues are intermittent but seem to occur most often around midday. Which of the following is the MOST likely cause?

    • There is interference from small appliances
    • The signal coverage area is too small
    • Not enough DHCP addresses have been allotted
    • The DNS cache on the users’ computers has become corrupt

18. A user reports difficulties connecting a PC to a wired network. The PC connects to an IP phone, which is working correctly. A network technician can verify that other devices successfully connect to the phone. At which of the following layers of the OSI model is the problem MOST likely located?
