13 Which of the following is not a single sign-on implementation?KerberosADFSCASRADIUS
14 As shown in the following image, a user on a Windows system is not able to use the Send Message functionality. What access control model best describes this type of limitation?Least privilegeNeed to know Constrained interfaceSeparation of duties
15 What type of access controls allow the owner of a file to grant other users access to it using an access control list?Role-basedNondiscretionaryRule-basedDiscretionary
16 Alex's job requires him to see protected health information (PHI) to ensure proper treatment of patients. His access to their medical records does not provide access to patient addresses or billing information. What access control concept best describes this control?Separation of dutiesConstrained interfacesContext-dependent controlNeed to knowFor questions 17–19, please use your knowledge of the Kerberos logon process and refer to the following diagram:
17 At point A in the diagram, the client sends the username and password to the KDC. How is the username and password protected?3DES encryptionTLS encryption SSL encryptionAES encryption
18 At point B in the diagram, what two important elements does the KDC send to the client after verifying that the username is valid?An encrypted TGT and a public keyAn access ticket and a public keyAn encrypted, time-stamped TGT and a symmetric key encrypted with a hash of the user's passwordAn encrypted, time-stamped TGT and an access token
19 What tasks must the client perform before it can use the TGT?It must generate a hash of the TGT and decrypt the symmetric key.It must accept the TGT and decrypt the symmetric key.It must decrypt the TGT and the symmetric key.It must send a valid response using the symmetric key to the KDC and must install the TGT.
20 Jacob is planning his organization's biometric authentication system and is considering retina scans. What concern may be raised about retina scans by others in his organization?Retina scans can reveal information about medical conditions.Retina scans are painful because they require a puff of air in the user's eye.Retina scanners are the most expensive type of biometric device.Retina scanners have a high false positive rate and will cause support issues.
