Q231. An administrator configures all wireless access points to make use of a new network certificate authority. Which of the following is being used? 

A. WEP 

B. LEAP 

C. EAP-TLS 

D. TKIP 

Answer:

Explanation: 

The majority of the EAP-TLS implementations require client-side X.509 certificates without giving the option to disable the requirement. 


Q232. Disabling unnecessary services, restricting administrative access, and enabling auditing controls on a server are forms of which of the following? 

A. Application patch management 

B. Cross-site scripting prevention 

C. Creating a security baseline 

D. System hardening 

Answer:

Explanation: 

Hardening is the process of securing a system by reducing its surface of vulnerability. Reducing the surface of vulnerability typically includes removing or disabling unnecessary functions and features, removing or disabling unnecessary user accounts, disabling unnecessary protocols and ports, and disabling unnecessary services. 


Q233. The helpdesk reports increased calls from clients reporting spikes in malware infections on their systems. Which of the following phases of incident response is MOST appropriate as a FIRST response? 

A. Recovery 

B. Follow-up 

C. Validation 

D. Identification 

E. Eradication 

F. Containment 

Answer:

Explanation: 

To be able to respond to the incident of malware infection you need to know what type of malware was used since there are many types of malware around. This makes identification critical in this case. 


Q234. Which of the following is a directional antenna that can be used in point-to-point or point-to-multi-point WiFi communication systems? (Select TWO). 

A. Backfire 

B. Dipole 

C. Omni 

D. PTZ 

E. Dish 

Answer: A,E 

Explanation: 


Q235. The librarian wants to secure the public Internet kiosk PCs at the back of the library. Which of the following would be the MOST appropriate? (Select TWO). 

A. Device encryption 

B. Antivirus 

C. Privacy screen 

D. Cable locks 

E. Remote wipe 

Answer: B,D 

Explanation: 

B: Antivirus software is used to protect systems against viruses, which are a form of malicious code designed to spread from one system to another, consuming network resources. Public systems are particularly prone to viruses. 

D: Cable locks are theft deterrent devices that can be used to tether a device to a fixed point keep devices from being easy to steal. 


Down to date SY0-401 test questions:

Q236. A new intern was assigned to the system engineering department, which consists of the system architect and system software developer’s teams. These two teams have separate privileges. The intern requires privileges to view the system architectural drawings and comment on some software development projects. Which of the following methods should the system administrator implement? 

A. Group based privileges 

B. Generic account prohibition 

C. User access review 

D. Credential management 

Answer:

Explanation: 

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). By assigning the intern’s user account to both groups, the intern will inherit the permissions assigned to those groups. 


Q237. Pete, the system administrator, has concerns regarding users losing their company provided smartphones. Pete’s focus is on equipment recovery. Which of the following BEST addresses his concerns? 

A. Enforce device passwords. 

B. Use remote sanitation. 

C. Enable GPS tracking. 

D. Encrypt stored data. 

Answer:

Explanation: 

Global Positioning System (GPS) tracking can be used to identify its location of a stolen device and can allow authorities to recover the device. However, for GPS tracking to work, the device must have an Internet connection or a wireless phone service over which to send its location information. 


Q238. Which of the following implementation steps would be appropriate for a public wireless hot-spot? 

A. Reduce power level 

B. Disable SSID broadcast 

C. Open system authentication 

D. MAC filter 

Answer:

Explanation: 

For a public wireless hot-spot, you want members of the public to be able to access the wireless network without having to provide them with a password. Therefore, Open System Authentication is the best solution. 

Open System Authentication (OSA) is a process by which a computer can gain access to a wireless network that uses the Wired Equivalent Privacy (WEP) protocol. With OSA, a computer equipped with a wireless modem can access any WEP network and receive files that are not encrypted. For OSA to work, the service set identifier (SSID) of the computer should match the SSID of the wireless access point. The SSID is a sequence of characters that uniquely names a wireless local area network (WLAN). The process occurs in three steps. First, the computer sends a request for authentication to the access point. Then the access point generates an authentication code, usually at random, intended for use only during that session. Finally, the computer accepts the authentication code and becomes part of the network as long as the session continues and the computer remains within range of the original access point. If it is necessary to exchange encrypted data between a WEP network access point and a wireless-equipped computer, a stronger authentication process called Shared Key Authentication (SKA) is required. 


Q239. Which of the following risk concepts requires an organization to determine the number of failures per year? 

A. SLE 

B. ALE 

C. MTBF 

D. Quantitative analysis 

Answer:

Explanation: 

ALE is the annual loss expectancy value. This is a monetary measure of how much loss you could expect in a year. 


Q240. The string: 

‘ or 1=1-- -

Represents which of the following? 

A. Bluejacking 

B. Rogue access point 

C. SQL Injection 

D. Client-side attacks 

Answer:

Explanation: 

The code in the question is an example of a SQL Injection attack. The code ‘1=1’ will always provide a value of true. This can be included in statement designed to return all rows in a SQL table. 

SQL injection is a code injection technique, used to attack data-driven applications, in which malicious SQL statements are inserted into an entry field for execution (e.g. to dump the database contents to the attacker). SQL injection must exploit a security vulnerability in an application's software, for example, when user input is either incorrectly filtered for string literal escape characters embedded in SQL statements or user input is not strongly typed and unexpectedly executed. SQL injection is mostly known as an attack vector for websites but can be used to attack any type of SQL database.
