1. Which two statements are true regarding network security? (Choose two.)
Securing a network against internal threats is a lower priority because company employees represent a low security risk.
**Both experienced hackers who are capable of writing their own exploit code and inexperienced individuals who download exploits from the Internet pose a serious threat to network security.
Assuming a company locates its web server outside the firewall and has adequate backups of the web server, no further security measures are needed to protect the web server because no harm can come from it being hacked.
Established network operating systems like UNIX and network protocols like TCP/IP can be used with their default settings because they have no inherent security weaknesses.
** Protecting network devices from physical damage caused by water or electricity is a necessary part of the security policy.

2. Which two statements are true about network attacks? (Choose two.)
Strong network passwords mitigate most DoS attacks.
Worms require human interaction to spread, viruses do not.
Reconnaissance attacks are always electronic in nature, such as ping sweeps or port scans.
** A bruteforce attack searches to try every possible password from a combination of characters.
** Devices in the DMZ should not be fully trusted by internal devices, and communication between the DMZ and internal devices should be authenticated to prevent attacks such as port redirection.

3. Users are unable to access a company server. The system logs show that the server is operating slowly because it is receiving a high level of fake requests for service. Which type of attack is occurring?
reconnaissance
access
** DoS
worm
virus
Trojan horse

4. An IT director has begun a campaign to remind users to avoid opening email messages from suspicious sources. Which type of attack is the IT director trying to protect users from?
DoS
DDoS
** virus
access
reconnaissance

physical
• data link
network
transport

3. What is one example of a physical layer problem?
incorrect encapsulation
incorrect STP configuration
incorrect ARP mapping
• incorrect clock rate

4. Which two components should be taken into consideration when establishing a network baseline? (Choose two.)
• information about the network design
IP addressing allocation on the network
requirements about the service provider setup
requirements for access control lists to regulate traffic
• expected performance under normal operating conditions

5.

Refer to the exhibit. Which two steps should be taken during the process of creating network documentation? (Choose two.)
Record the information about the devices discovered in the Campus network only.
• Record the information about the devices discovered in the entire network, including the remote locations.
• Transfer any information about the devices from the network configuration table that corresponds to a component of the topology diagram.
Transfer only the Layer 2 and Layer 3 information about the devices from the network configuration table that corresponds to a component of the topology diagram.
Transfer the recorded information about the devices from the network configuration table gathered during peak network utilization that corresponds to a component of the topology diagram.

6. Which two statements are true concerning logical networking models? (Choose two.)
TCP/IP splits the lowest layer of the OSI model into two separate layers.
• The top layer of the TCP/IP model combines the functions of the top three OSI layers.
Troubleshooting with the TCP/IP model requires different techniques than with the OSI model.
The network access layer is responsible for exchanging packets between devices on a TCP/IP network.
The Internet layer provides communication between applications, such as FTP, HTTP, and SMTP on separate hosts.
• The TCP/IP network access layer corresponds to the OSI physical and data link layers.
