    Which of the following packet filtering criteria enable you to prevent a denial-ofservice attack using ICMP messages?

    • A.

      Port numbers

    • B.

      Hardware addresses

    • C.

      Protocol identifiers

    • D.

      IP addresses

    Correct Answer
    C. Protocol identifiers
    Explanation
    Protocol identifiers allow you to filter and block specific types of network protocols, such as ICMP (Internet Control Message Protocol). By blocking ICMP messages, you can prevent certain types of denial-of-service attacks that rely on flooding a target with ICMP packets. Port numbers and hardware addresses are not directly related to preventing ICMP-based denial-of-service attacks. IP addresses can be used for filtering, but they do not specifically target ICMP messages.

    Which of the following ESP header fields provides the protocol’s anti-replay capability?

    • A.

      Sequence Number

    • B.

      Security Parameters Index

    • C.

      Pad Length

    • D.

      Next Header

    Correct Answer
    A. Sequence Number
    Explanation
    The Sequence Number field in the ESP (Encapsulating Security Payload) header provides the protocol's anti-replay capability. This field is used to prevent attackers from intercepting and replaying previously captured packets, ensuring the integrity and security of the communication. By assigning a unique sequence number to each packet, the receiver can detect and discard any duplicate or out-of-order packets, protecting against replay attacks.

    Rate this question:

  • 4. 

    Which of the following IPSec characteristics is different when a connection is operating in tunnel mode instead of transport mode? (Choose all that apply.)

    • A.

      The order of the fields in the ESP header

    • B.

      The location of the ESP header in the datagram

    • C.

      The location of the ESP trailer in the datagram

    • D.

      The value of the Next Header field in the ESP header

    Correct Answer(s)
    B. The location of the ESP header in the datagram
    D. The value of the Next Header field in the ESP header
    Explanation
    In tunnel mode, the ESP header is inserted between the original IP header and the rest of the original datagram, thereby changing the location of the ESP header in the datagram. Additionally, the value of the Next Header field in the ESP header is changed to reflect the protocol of the original IP header. The order of the fields in the ESP header and the location of the ESP trailer in the datagram remain the same in both tunnel and transport modes.

    Rate this question:

    Which IPSec policy can you use to encrypt all traffic to and from a particular database application on a server running Windows Server 2003?

    • A.

      Client (Respond Only).

    • B.

      Secure Server (Require Security).

    • C.

      Server (Request Security).

    • D.

      You must create a new custom policy.

    Correct Answer
    D. You must create a new custom policy.
    Explanation
    A new custom policy needs to be created in order to encrypt all traffic to and from a particular database application on a server running Windows Server 2003. This is because none of the available IPSec policies mentioned in the options (Client (Respond Only), Secure Server (Require Security), Server (Request Security)) specifically address the requirement to encrypt all traffic for a specific application. Therefore, a custom policy needs to be created to meet this specific encryption requirement.

    Rate this question:

  • 6. 

    Which of the following pieces of information must you supply when creating a policy that configures IPSec to use tunnel mode?

    • A.

      The IP address of the router’s WAN interface

      The port number associated with the WAN technology used for the tunnel

    • C.

      The IP address of the router at the far end of the tunnel

    • D.

      The network layer protocol used for the WAN connection

    Correct Answer
    A. The IP address of the router’s WAN interface
    Explanation
    When creating a policy that configures IPSec to use tunnel mode, you must supply the IP address of the router's WAN interface. This is necessary because the router's WAN interface is the entry point for the tunnel and serves as the endpoint for the IPSec communication. By providing the IP address of the router's WAN interface, the IPSec policy can establish the tunnel and ensure secure communication between the local and remote networks.

  • 10. 

    Which of the following IPSec policies should you assign to the organizational unit object containing the R&D users’ workstations?

    • A.

      The default Secure Server (Require Security) policy

    • B.

      The default Client (Respond Only) policy

    • C.

      A policy that secures all TCP traffic, using both the AH and ESP protocols

    • D.

      A policy that secures all traffic to the port number of the database application, using the AH protocol

    Correct Answer
    B. The default Client (Respond Only) policy
    Explanation
    The default Client (Respond Only) policy is the most suitable choice for the organizational unit object containing the R&D users' workstations. This policy allows the workstations to respond to requests for security negotiations initiated by other computers. This means that the workstations will only establish secure connections when requested by other devices, ensuring that their security is maintained while still allowing them to communicate with other systems as needed.

    Rate this question:

  • 11. 

    Which of the following procedures should you use to secure the WAN traffic between the users in the company headquarters and the R&D database servers?  Choose all that apply.)

    • A.

      Configure the routers at both ends of the WAN connection to use IPSec in tunnel mode

    • B.

      Configure the database servers with the Secure Server (Require Security) policy

    • C.

      Configure the workstations of the users at the headquarters with the Client (Respond Only) policy

    • D.

      Configure the database servers and the workstations at the headquarters to use IPSec in tunnel mode

    Correct Answer(s)
    B. Configure the database servers with the Secure Server (Require Security) policy
    C. Configure the workstations of the users at the headquarters with the Client (Respond Only) policy
    Explanation
    To secure the WAN traffic between the users in the company headquarters and the R&D database servers, the correct procedures to use are configuring the database servers with the Secure Server (Require Security) policy and configuring the workstations of the users at the headquarters with the Client (Respond Only) policy. These policies ensure that the database servers and workstations are configured to enforce security measures and respond to security requests, respectively. This helps in protecting the data and communication between the users and the servers. Configuring the routers with IPSec in tunnel mode is not necessary in this scenario as the question specifically asks for procedures to secure the traffic between the users and the servers, not the routers.
