• Device control for data transmission rates
• Enabling of communication between network clients and services
• Standard setting for sending and receiving signals
• Integration of network functionality into the host operating system

2. Which of the following are included as part of the Data Link layer specifications? (Choose two)

• Data transmission between hosts
• Cable and connector specifications
• Physical topology
• Physical network device identification
• Digital data conversion

3. Which stratum level does the authoritative time device fall under?

• 3
• 1
• 2
• 0

4. You manage a network that has multiple internal subnets. You connect a workstation to the 192.168.1.0/24 subnet. This workstation cannot communicate with any other host on the network. You run ipconfig /all and see the following:

Ethernet adapter Local Area Connection:
Connection-specific DNS Suffix. : mydomain.local
Description . . . . . . . : Broadcom network adapter
Physical Address . . . . . : 00-AA-BB-CC-74-EF
DHCP Enabled. . . . . . . : No
Autoconfiguration Enabled . . : Yes
IPv4 Address. . . . . . . : 192.168.2.102(Preferred)
Subnet Mask . . . . . . . : 255.255.255.0
Default Gateway. . . . . . : 192.168.1.1
DNS Servers . . . . . . . : 192.168.2.20

What is the MOST likely cause of the problem?

• Incorrect subnet mask
• Incorrect DNS server address
• Incorrect default gateway
• Incorrect IP address

5. Which IDS traffic assessment indicates that the system identified traffic as offensive and generated an alarm or stopped the traffic?

7. Which of the following provides a VPN gateway that encapsulates and encrypts outbound traffic from a site and sends the traffic through a VPN tunnel to the VPN gateway at the target site?

• Remote access VPN
• Site-to-site IPsec VPN
• GRE over IPsec
• SSL VPN

8. What is a VPN (virtual private network) primarily used for?

• Allow remote systems to save on long distance charges.
• Support secure communications over an untrusted network.
• Allow the use of network-attached printers.
• Support the distribution of public web documents.

9. You have been using SNMP on your network for monitoring and management, but you're concerned about the security of this configuration. What should you do to increase security in this situation?

• Combine SNMP with SSL.
• Implement a RADIUS solution.
• Implement version 3 of SNMP.
• Use SSH instead of SNMP.

10. You suspect that a bad video driver is causing a user's system to randomly crash and reboot. Where would you go to identify and confirm your suspicions?

• Syslog
• Dump files
• Application logs
• SIP logs
