Question No: 41 – (Topic 1)

A review of the company’s network traffic shows that most of the malware infections are caused by users visiting gambling and gaming websites. The security manager wants to implement a solution that will block these websites, scan all web traffic for signs of malware, and block the malware before it enters the company network. Which of the following is suited for this purpose?

  1. ACL

  2. IDS

  3. UTM

  4. Firewall

Answer: C Explanation:

An all-in-one appliance, also known as Unified Threat Management (UTM) and Next Generation Firewall (NGFW), is one that provides a good foundation for security. A variety is available; those that you should be familiar with for the exam fall under the categories of providing URL filtering, content inspection, or malware inspection.

Malware inspection is the use of a malware scanner to detect unwanted software content in network traffic. If malware is detected, it can be blocked or logged and/or trigger an alert.

Question No: 42 – (Topic 1)

Which of the following is a difference between TFTP and FTP?

  1. TFTP is slower than FTP.

  2. TFTP is more secure than FTP.

  3. TFTP utilizes TCP and FTP uses UDP.

  4. TFTP utilizes UDP and FTP uses TCP.

Answer: D Explanation:

FTP employs TCP ports 20 and 21 to establish and maintain client-to-server communications, whereas TFTP makes use of UDP port 69.

Question No: 43 – (Topic 1)

A company has proprietary mission critical devices connected to their network which are configured remotely by both employees and approved customers. The administrator wants to monitor device security without changing their baseline configuration. Which of the following should be implemented to secure the devices without risking availability?

  1. Host-based firewall

  2. IDS

  3. IPS

  4. Honeypot

Answer: B Explanation:

An intrusion detection system (IDS) is a device or software application that monitors network or system activities for malicious activities or policy violations and produces reports to a management station. IDS come in a variety of “flavors” and approach the goal of detecting suspicious traffic in different ways. There are network based (NIDS) and host based (HIDS) intrusion detection systems. Some systems may attempt to stop an intrusion attempt but this is neither required nor expected of a monitoring system. Intrusion detection and prevention systems (IDPS) are primarily focused on identifying possible incidents, logging information about them, and reporting attempts. In addition, organizations use IDPSes for other purposes, such as identifying problems with security policies, documenting existing threats and deterring individuals from violating security policies.

IDPSes have become a necessary addition to the security infrastructure of nearly every organization.

IDPSes typically record information related to observed events, notify security administrators of important observed events and produce reports. Many IDPSes can also respond to a detected threat by attempting to prevent it from succeeding. They use several response techniques, which involve the IDPS stopping the attack itself, changing the security environment (e.g. reconfiguring a firewall) or changing the attack#39;s content.

Question No: 44 – (Topic 1)

An administrator wants to establish a WiFi network using a high gain directional antenna with a narrow radiation pattern to connect two buildings separated by a very long distance. Which of the following antennas would be BEST for this situation?

  1. Dipole

  2. Yagi

  3. Sector

  4. Omni

Answer: B Explanation:

A Yagi-Uda antenna, commonly known simply as a Yagi antenna, is a directional antenna consisting of multiple parallel dipole elements in a line, usually made of metal rods. It consists of a single driven element connected to the transmitter or receiver with a transmission line, and additional parasitic elements: a so-called reflector and one or more directors. The reflector element is slightly longer than the driven dipole, whereas the directors are a little shorter. This design achieves a very substantial increase in the antenna#39;s directionality and gain compared to a simple dipole.

Question No: 45 – (Topic 1)

An administrator is looking to implement a security device which will be able to not only detect network intrusions at the organization level, but help defend against them as well. Which of the following is being described here?

  1. NIDS

  2. NIPS

  3. HIPS

  4. HIDS

Answer: B Explanation:

Network-based intrusion prevention system (NIPS) monitors the entire network for suspicious traffic by analyzing protocol activity. The main functions of intrusion prevention

systems are to identify malicious activity, log information about this activity, attempt to block/stop it, and report it

Question No: 46 – (Topic 1)

An administrator needs to segment internal traffic between layer 2 devices within the LAN. Which of the following types of network design elements would MOST likely be used?

  1. Routing

  2. DMZ

  3. VLAN

  4. NAT

Answer: C Explanation:

A virtual local area network (VLAN) is a hardware-imposed network segmentation created by switches. VLANs are used for traffic management. Communications between ports within the same VLAN occur without hindrance, but communications between VLANs require a routing function.

Question No: 47 – (Topic 1)

Mike, a network administrator, has been asked to passively monitor network traffic to the company’s sales websites. Which of the following would be BEST suited for this task?

  1. HIDS

  2. Firewall

  3. NIPS

  4. Spam filter

Answer: C Explanation:

Network-based intrusion prevention system (NIPS) monitors the entire network for suspicious traffic by analyzing protocol activity.

Question No: 48 – (Topic 1)

An access point has been configured for AES encryption but a client is unable to connect to it. Which of the following should be configured on the client to fix this issue?

  1. WEP

  2. CCMP

  3. TKIP

  4. RC4

Answer: B Explanation:

CCMP is an encryption protocol designed for Wireless LAN products that implement the standards of the IEEE 802.11i amendment to the original IEEE 802.11 standard. CCMP is an enhanced data cryptographic encapsulation mechanism designed for data confidentiality and based upon the Counter Mode with CBC-MAC (CCM) of the AES standard.

Question No: 49 – (Topic 1)

Pete, the system administrator, wants to restrict access to advertisements, games, and gambling web sites. Which of the following devices would BEST achieve this goal?

  1. Firewall

  2. Switch

  3. URL content filter

  4. Spam filter

Answer: C Explanation:

URL filtering, also known as web filtering, is the act of blocking access to a site based on all or part of the URL used to request access. URL filtering can focus on all or part of a fully qualified domain name (FQDN), specific path names, specific filenames, specific fi le extensions, or entire specific URLs. Many URL-filtering tools can obtain updated master URL block lists from vendors as well as allow administrators to add or remove URLs from a custom list.

Question No: 50 – (Topic 1)

The Chief Information Security Officer (CISO) has mandated that all IT systems with credit card data be segregated from the main corporate network to prevent unauthorized access and that access to the IT systems should be logged. Which of the following would BEST meet the CISO’s requirements?

  1. Sniffers

  2. NIDS

  3. Firewalls

  4. Web proxies

  5. Layer 2 switches

Answer: C Explanation:

The basic purpose of a firewall is to isolate one network from another.
