is ccna harder than network+.13.5 Post-Lesson Exercise 507a. This attack is used to "create" two or more duplicate sliced IP packets by "carefully" setting the value of the slice offset field in the IP packet headerb. This attack is performed by setting the TCP value in the IP packet header to a mismatch, causing one slice to be duplicated by another. c. This attack is performed by setting the UDP value in the IP packet header to a match, causing one slice to be duplicated by another. d. This attack is performed by setting the TCP value in the IP packet header to a match, causing one slice to be duplicated by another.d.The technique for this attack is to set the offset value in the IP packet header to a mismatch, causing one slice to duplicate another6.Which of the following is the most correct description of a timing attack? a. sends a giant stream to disable the system or data b. sends traffic slowly at a rate lower than the system can accept c. sends traffic at a rate slow enough that the system will ignore it although it can accept it d. sends traffic for various protocols7.Which of the following operations is consistent with the techniques of a traffic substitution and insertion attack? a. Entering characters beyond what is required b. Using functions and classes c. Replacing spaces with tabs d. Entering wildcards8.Which of the following operations would not be used to launch an axial attack on a network? a. exploit vulnerabilities in hosts within the same network b. cut a back door into the networkc. VLAN hopping d. Exploiting a vulnerability in a web server9.Why would using the Cisco Identity Services Engine (ISE) reduce the risk of this attack when launching an axial attack against a trusted network with a higher level of security?a. ISE allows the system to upgrade the antivirus software's virus database to the latest version before being granted access to the network
