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

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

• 3
• 1
• 0
• 2

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

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

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

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?

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

• SIP logs
• Syslog
• Dump files
