A. Selecting identification versus authentication
B. Determining the list of exceptions
C. Choosing an encryption algorithm
D. Setting time of day restrictions
Answer: B
Explanation:

Q624. A security administrator is tasked with calculating the total ALE on servers. In a two year period of time, a company has to replace five servers. Each server replacement has cost the company $4,000 with downtime costing $3,000. Which of the following is the ALE for the company?
A. $7,000
B. $10,000
C. $17,500
D. $35,000
Answer: C
Explanation:
SLE × ARO = ALE, where SLE is equal to asset value (AV) times exposure factor (EF); and ARO is the annualized rate of occurrence. SLE =($4000 + $3000) x 5 = $35000 ARO = 2 years Thus per year it would be 50% = 0,5 The ALE is thus $35000 x 0.5 = $17500
Q625. Privilege creep among long-term employees can be mitigated by which of the following procedures?
A. User permission reviews
B. Mandatory vacations
C. Separation of duties
D. Job function rotation
Answer: A
Explanation:
Privilege creep is the steady build-up of access rights beyond what a user requires to perform his/her task.

Q626. A network administrator is configuring access control for the sales department which has high employee turnover. Which of the following is BEST suited when assigning user rights to individuals in the sales department?
A. Time of day restrictions
B. Group based privileges
C. User assigned privileges
D. Domain admin restrictions
Answer: B
Explanation:
The question states that the sales department has a high employee turnover. You can assign permissions to access resources either to a user or a group. The most efficient way is to assign permissions to a group (group based privileges). Then when a new employee starts, you simply add the new user account to the appropriate groups. The user then inherits all the permissions assigned to the groups.

B. Enable MAC filtering
C. Upgrade to WPA2 encryption

Q628. In which of the following scenarios is PKI LEAST hardened?
A. The CRL is posted to a publicly accessible location.
B. The recorded time offsets are developed with symmetric keys.
C. A malicious CA certificate is loaded on all the clients.
D. All public keys are accessed by an unauthorized user.
Answer: C
Explanation:
A rogue Certification Authority (CA) certificate allows malicious users to impersonate any Web site on the Internet, including banking and e-commerce sites secured using the HTTPS protocol. A rogue CA certificate would be seen as trusted by Web browsers, and it is harmful because it can appear to be signed by one of the root CAs that browsers trust by default. A rogue Certification Authority (CA) certificate can be created using a vulnerability in the Internet Public Key Infrastructure (PKI) used to issue digital certificates for secure Web sites.

A. Dual-factor authentication
B. Multifactor authentication
C. Single factor authentication
D. Biometric authentication
Answer: C
Explanation:
Multi-factor authentication (MFA) is a method of computer access control which a user can pass by successfully presenting authentication factors from at least two of the three categories: knowledge factors ("things only the user knows"), such as passwords possession factors ("things only the user has"), such as ATM cards inherence factors ("things only the user is"), such as biometrics
In this question a username, password, and a four-digit security pin knowledge are all knowledge factors (something the user knows). Therefore, this is single-factor authentication.
