   Explanation:
   1: Spear phishing is an e-mail spoofing fraud attempt that targets a specific organization, seeking unauthorized access to confidential data. As with the e-mail messages used in regular phishing expeditions, spear phishing messages appear to come from a trusted source. Phishing messages usually appear to come from a large and well-known company or Web site with a broad membership base, such as eBay or PayPal. In the case of spear phishing, however, the apparent source of the e-mail is likely to be an individual within the recipient’s own company and generally someone in a position of authority.

   2: The Hoax in this question is designed to make people believe that the fake AV (anti- virus) software is genuine.

   3: Vishing is the act of using the telephone in an attempt to scam the user into surrendering private information that will be used for identity theft. The scammer usually pretends to be a legitimate business, and fools the victim into thinking he or she will profit.

   4: Email spam, also referred to as junk email, is unsolicited messages sent in bulk by email (spamming).

   5: Similar in nature to e-mail phishing, pharming seeks to obtain personal or private (usually financial related) information through domain spoofing. Rather than being spammed with malicious and mischievous e-mail requests for you to visit spoof Web sites which appear legitimate, pharming ‘poisons’ a DNS server by infusing false information into the DNS server, resulting in a user’s request being redirected elsewhere. Your browser, however will show you are at the correct Web site, which makes pharming a bit more serious and more difficult to detect. Phishing attempts to scam people one at a time with an e-mail while pharming allows the scammers to target large groups of people at one time through domain spoofing.

3. DRAG DROP

   You have been tasked with designing a security plan for your company.

   INSTRUCTIONS

   Drag and drop the appropriate security controls on the floor plan.

   All objects must be used and all place holders must be filled. Order does not matter.

Which of the following should the security analyst do to determine if the compromised system still has an active connection?

   • tracert

   • netstat

   • ping

   • nslookup

6. Multiple organizations operating in the same vertical want to provide seamless wireless access for their employees as they visit the other organizations. Which of the following should be implemented if all the organizations use the native 802.1x client on their mobile devices?

   • Shibboleth

   • OAuth
   • OpenID connect

7. Which of the following BEST describes an important security advantage yielded by implementing vendor diversity?

   • Sustainability
   • Homogeneity
   • Resiliency
   • Configurability

8. In a corporation where compute utilization spikes several times a year, the Chief Information Officer (CIO) has requested a cost-effective architecture to handle the variable capacity demand. Which of the following characteristics BEST describes what the CIO has requested?

   • Elasticity
   • Scalability
   • High availability
   • Redundancy
   Explanation:

   Elasticity is defined as “the degree to which a system is able to adapt to workload changes by provisioning and de-provisioning resources in an autonomic manner, such that at each point in time the available resources match the current demand as closely as possible”.

9. A security engineer is configuring a system that requires the X.509 certificate information to be pasted into a form field in Base64 encoded format to import it into the system. Which of the following certificate formats should the engineer use to obtain the information in the required format?

   • PFX
   • PEM
   • DER
   • CER

10. Which of the following attacks specifically impact data availability?

    • DDoS
    • Trojan
    • MITM
    • Rootkit

11. A security analyst is hardening a server with the directory services role installed. The analyst must ensure LDAP traffic cannot be monitored or sniffed and maintains compatibility with LDAP clients. Which of the following should the analyst implement to meet these requirements? (Choose two.)

    • Generate an X.509-compliant certificate that is signed by a trusted CA.
    • Install and configure an SSH tunnel on the LDAP server.
    • Ensure port 389 is open between the clients and the servers using the communication.
    • Ensure port 636 is open between the clients and the servers using the communication.
