Question 3

You are tasked with securing a small network for a client in which the following requirements must be met:
• If a user on the private network attempts to send confidential company information to an unauthorized entity, an alert should be triggered.
• The private trusted network should not be accessible from the public untrusted network.
• If attacks are coming from the external network, the system should detect and prevent malicious activity.
• All incoming and outgoing email should be scanned for malware.
   
Which of the following would best meet the requirements of the client?
A) Implement a firewall.
B) Implement an IPS.
C) Implement a UTM appliance.
D) Implement identity-based ACLs.
E) Implement an IDS.

Accepted Answer

A UTM (Unified Threat Management) appliance is designed to provide multiple security features such as firewall, intrusion prevention (IPS), malware scanning, and more in a single device. This makes it suitable for meeting all the listed requirements including triggering alerts for unauthorized data transmission, protecting the private network from the public, detecting and preventing attacks, and scanning emails for malware.

Question 4

Consider the following configuration.
Computer "A"
                  IP address:           172.16.100.100
                  Subnet mask:      255.255.0.0
Computer "B"
                  IP address:           172.16.200.200
                  Subnet mask:      /16
What should be done to allow these computers to send and receive data to and from each other?
A) Nothing needs to be changed.
B) Delete the subnet mask from each computer.
C) A router must be configured and placed between the two computers.
D) Remove the hub between the two computers and replace it with a switch.

Accepted Answer

Both computers are in the same subnet (172.16.0.0/16), so they can communicate directly without any changes.

Question 5

A company requires an Ethernet connection from the north end of its office building to the south end. The distance between connections is 161 meters and will need to provide speeds of up to 10 Gbps in full duplex mode.
Which of the following cable combinations will meet these requirements?
A) Coaxial cable with BNC connectors
B) Cat6 STP cable with RJ-45 connectors
C) Multimode fiber cable with MT-RJ connectors
D) Cat5e UTP cable with RJ-45 connectors

Accepted Answer

Multimode fiber cable with MT-RJ connectors is the best option for covering a distance of 161 meters while providing speeds of up to 10 Gbps in full duplex mode. Coaxial, Cat6, and Cat5e cables either do not support the required distance at the desired speed or are not suitable for such high-speed data transmission over this distance. Fiber optic cables, like the multimode fiber specified, are capable of transmitting data at high speeds over longer distances without significant signal degradation.

Question 6

A technician is installing UTP cable and needs to terminate the connections on the patch panel shown in the following image.

What tool should be used to terminate and complete this installation?
A) Crimper tool
B) Punchdown tool
C) Cable stripper

Question 7

A server provides the necessary IP configuration to your network host so the host can communicate on the network. If this service malfunctions, your device will not be able to utilize the network.
What server provides this service?
A) DHCP server
B) DNS server
C) Proxy server
D) Syslog server

Accepted Answer

A DHCP (Dynamic Host Configuration Protocol) server automatically assigns IP addresses and other network configuration parameters to devices on a network, enabling them to communicate with other IP networks.

Question 8

B) Scanning incoming and outgoing corporate email for spam, malware, and viruses.
C) Restricting a device's access to the network until security requirements are met.
D) Providing authentication services for all network-connected devices.

Accepted Answer

Endpoint management server appliances are designed to ensure that devices comply with security policies before they can access the network. This includes checking for updated antivirus software, system updates, and other security requirements. Restricting access until these conditions are met is a key function of such systems.

Question 15

Your company is experiencing an increase in malware incidents. Your manager is asking for advice on how best to verify that company-owned workstations are up-to-date with security patches, anti-malware requirements, and software application updates. The manager is also concerned that employee-owned devices connecting to the corporate LAN have the same level of security as the company devices.
Which of the following protections and services should you recommend?
A) Implement a firewall with packet inspection.
B) Implement an intrusion detection system appliance.
C) Implement an endpoint management server appliance.
D) Implement an intrusion prevention system.

Accepted Answer

Implementing an endpoint management server appliance allows for centralized management of security policies, ensuring that all devices, including company-owned workstations and employee-owned devices connecting to the corporate LAN, are up-to-date with security patches, anti-malware requirements, and software application updates. This directly addresses the manager's concerns about verifying and maintaining the security level of all devices within the corporate network.

Question 16

You received a call from a user who brought her own device to the office but cannot find or connect to the company WLAN. The laptop shows other available wireless networks in the building. This user and the other users in her department are connected to the company WLAN and can browse to multiple websites with no problems from their company-assigned laptops.
Which of the following is the most likely reason the user cannot find the company WLAN from her own device?
A) The company WAP has its radio turned off.
B) The company WAP is powered down or disconnected.
C) The laptop's wireless network is toggled to the off position.
D) The company WAP has SSID broadcast disabled.
E) The user's laptop NIC has MAC address filtering enabled.

Accepted Answer

The most likely reason the user cannot find the company WLAN from her own device is that the company Wireless Access Point (WAP) has SSID broadcast disabled. This means the network name (SSID) is not being openly broadcasted, making it invisible to devices not already configured to connect to it. Other networks being visible indicates the user's device and the WAP are functioning, but the specific network is hidden.

Question 17

Question 19

Your company received a call from a historical society inquiring about the possibility of networking a two-century-old building with no existing network. In 1924, someone added electrical outlets to the building, but the layout and design of the building prohibits adding any additional copper or fiber cable. You completed a wireless site survey and concluded that wireless networking is out of the question and will not properly function due to environmental interference.
Which of the following could be used to network this building?
A) PoE
B) EoP
C) WAP
D) NIC
E) NAT

Accepted Answer

EoP (Ethernet over Power) can be used in this scenario because it utilizes the existing electrical wiring for network connectivity, which is ideal since the building cannot have new cables added and wireless options are not viable due to interference.

Question 20

A technician is troubleshooting a small network with cable Internet service in which a user is receiving a message in her web browser stating a site cannot be found. While interviewing users, it is determined that every host on the network is experiencing the same issue with all websites.
Which of the following is the first step in troubleshooting this issue?
A) Use a cable tester to test the patch cable for the first user who reported the issue.
B) Reboot the SOHO router connecting the LAN to the cable modem.
C) Call the Internet service provider and report the problem.
D) Replace the patch cable from the SOHO router to the cable modem.
E) Connect a computer directly to the cable modem and attempt to access the Internet.
