EC-COUNCIL 312-38 Online Questions & Answers

• Question 91:

  Paul is a network security technician working on a contract for a laptop manufacturing company in Chicago. He has focused primarily on securing network devices, firewalls, and traffic traversing in and out of the network. He just finished setting up a server a gateway between the internal private network and the outside public network. This server will act as a proxy, limited amount of services, and will filter packets. What is this type of server called?

  A. Session layer firewall.
  B. SOCKS host.
  C. Bastion host.
  D. Edge transport server.
  C. Bastion host.

• Question 92:

  Fill in the blank with the appropriate word. A policy is defined as the document that describes the scope of an organization's security requirements.

  security

  Explanation/Reference:

  A security policy is defined as the document that describes the scope of an organization's security requirements. Information security policies are usually documented in one or more information security policy documents. The policy includes the assets that are to be protected. It also provides security solutions to provide necessary protection against the security threats.

• Question 93:

  The _______ protocol works in the network layer and is responsible for handling the error codes during the delivery of packets. This protocol is also responsible for providing communication in the TCP/IP stack.

  A. RARP
  B. ICMP
  C. ARP
  D. DHCP
  B. ICMP

• Question 94:

  Which of the following is a network interconnectivity device that translates different communication protocols and is used to connect dissimilar network technologies?

  A. Gateway
  B. Router
  C. Bridge
  D. Switch
  A. Gateway

  ---

  Explanation/Reference:

  A gateway is a network interconnectivity device that translates different communication protocols and is used to connect dissimilar network technologies. It provides greater functionality than a router or bridge because a gateway functions both as a translator and a router. Gateways are slower than bridges and routers. A gateway is an application layer device.

  Answer option B is incorrect. A router is an electronic device that interconnects two or more computer networks. It selectively interchanges packets of data between them. It is a networking device whose software and hardware are customized

  to the tasks of routing and forwarding information. It helps in forwarding data packets between networks.

  Answer option C is incorrect. A bridge is an interconnectivity device that connects two local area networks (LANs) or two segments of the same LAN using the same communication protocols, and provides address filtering between them.

  Users can use this device to divide busy networks into segments and reduce network traffic. A bridge broadcasts data packets to all the possible destinations within a specific segment. Bridges operate at the data-link layer of the OSI model.

  Answer option D is incorrect. A switch is a network device that selects a path or circuit for sending a data unit to its next destination. It is not required in smaller networks, but is required in large inter-networks, where there can be many

  possible ways of transmitting a message from a sender to destination. The function of switch is to select the best possible path. On an Ethernet local area network (LAN), a switch determines from the physical device (Media Access Control or

  MAC) address in each incoming message frame which output port to forward it to and out of. In a wide area packet-switched network, such as the Internet, a switch determines from the IP address in each packet which output port to use for

  the next part of its trip to the intended destination.

• Question 95:

  Which type of wireless network threats an attacker stakes out the area from a nearby location with a high gain amplifier drowning out the legitimate access point?

  A. Rogue access point attack
  B. Jamming signal attack
  C. Ad Hoc Connection attack
  D. Unauthorized association
  B. Jamming signal attack

• Question 96:

  Which among the following is used to limit the number of cmdlets or administrative privileges of administrator, user, or service accounts?

  A. Just Enough Administration (EA)
  B. User Account Control (UAC)
  C. Windows Security Identifier (SID)
  D. Credential Guard
  A. Just Enough Administration (EA)

• Question 97:

  A. Root mode
  B. Full-duplex mode
  C. Half-duplex mode
  D. Simplex mode

• Question 98:

  Which of the following protocols is used to report an error in datagram processing?

  A. ARP
