Q351. Which of the following devices would MOST likely have a DMZ interface? 

A. Firewall 

B. Switch 

C. Load balancer 

D. Proxy 

Answer:

Explanation: The DMZ is a buffer network between the public untrusted Internet and the private trusted LAN. Often a DMZ is deployed through the use of a multihomed firewall. 


Q352. Which of the following would BEST deter an attacker trying to brute force 4-digit PIN numbers to access an account at a bank teller machine? 

A. Account expiration settings 

B. Complexity of PIN 

C. Account lockout settings 

D. PIN history requirements 

Answer:

Explanation: 

Account lockout settings determine the number of failed login attempts before the account gets locked and how long the account will be locked out for. For example, an account can be configured to lock if three incorrect passwords (or in this case PIN’s) are entered. The account can then be configured to automatically unlock after a period of time or stay locked until someone manually unlocks it. 


Q353. Elastic cloud computing environments often reuse the same physical hardware for multiple customers over time as virtual machines are instantiated and deleted. This has important implications for which of the following data security concerns? 

A. Hardware integrity 

B. Data confidentiality 

C. Availability of servers 

D. Integrity of data 

Answer:

Explanation: 

Data that is not kept separate or segregated will impact on that data’s confidentiality maybe being compromised. Be aware of the fact that your data is only as safe as the data with which it is integrated. For example, assume that your client database is hosted on a server that another company is also using to test an application that they are creating. If their application obtains root-level access at some point (such as to change passwords) and crashes at that point, then the user running the application could be left with root permissions and conceivably be to access data on the server for which they are not authorized, such as your client database. Data segregation is crucial; keep your data on secure servers. 


Q354. When designing a new network infrastructure, a security administrator requests that the intranet web server be placed in an isolated area of the network for security purposes. Which of the following design elements would be implemented to comply with the security administrator’s request? 

A. DMZ 

B. Cloud services 

C. Virtualization 

D. Sandboxing 

Answer:

Explanation: 

A demilitarized zone (DMZ) is an area of a network that is designed specifically for public users to access. The DMZ is a buffer network between the public untrusted Internet and the private trusted LAN. Often a DMZ is deployed through the use of a multihomed firewall. 


Q355. Which of the following can be implemented if a security administrator wants only certain devices connecting to the wireless network? 

A. Disable SSID broadcast 

B. Install a RADIUS server 

C. Enable MAC filtering 

D. Lowering power levels on the AP 

Answer:

Explanation: 

MAC filtering is commonly used in wireless networks. In computer networking, MAC Filtering (or GUI filtering, or layer 2 address filtering) refers to a security access control method whereby the 48-bit address assigned to each network card is used to determine access to the network. MAC addresses are uniquely assigned to each card, so using MAC filtering on a network permits and denies network access to specific devices through the use of blacklists and whitelists. While the restriction of network access through the use of lists is straightforward, an individual person is not identified by a MAC address, rather a device only, so an authorized person will need to have a whitelist entry for each device that he or she would use to access the network. 


Q356. Which of the following is true about the recovery agent? 

A. It can decrypt messages of users who lost their private key. 

B. It can recover both the private and public key of federated users. 

C. It can recover and provide users with their lost or private key. 

D. It can recover and provide users with their lost public key. 

Answer:

Explanation: 

Explanation: A key recovery agent is an entity that has the ability to recover a private key, key components, or plaintext messages as needed. Using the recovered key the recovery agent can decrypt encrypted data. 


Q357. A company is trying to limit the risk associated with the use of unapproved USB devices to copy documents. Which of the following would be the BEST technology control to use in this scenario? 

A. Content filtering 

B. IDS 

C. Audit logs 

D. DLP 

Answer:

Explanation: 

Data loss prevention (DLP) is a strategy for making sure that end users do not send sensitive or critical information outside the corporate network. The term is also used to describe software products that help a network administrator control what data end users can transfer. 


Q358. Company A submitted a bid on a contract to do work for Company B via email. Company B was insistent that the bid did not come from Company A. Which of the following would have assured that the bid was submitted by Company A? 

A. Steganography 

B. Hashing 

C. Encryption 

D. Digital Signatures 

Answer:

Explanation: 

A digital signature is similar in function to a standard signature on a document. It validates the integrity of the message and the sender. The message is encrypted using the encryption system, and a second piece of information, the digital signature, is added to the message. 


Q359. Which of the following technical controls is BEST used to define which applications a user can install and run on a company issued mobile device? 

A. Authentication 

B. Blacklisting 

C. Whitelisting 

D. Acceptable use policy 

Answer:

Explanation: 

White lists are closely related to ACLs and essentially, a white list is a list of items that are allowed. 


Q360. Which of the following protocols allows for the LARGEST address space? 

A. IPX 

B. IPv4 

C. IPv6 

D. Appletalk 

Answer:

Explanation: 

The main advantage of IPv6 over IPv4 is its larger address space. The length of an IPv6 address is 128 bits, compared with 32 bits in IPv4.
