Q321. A software development company wants to implement a digital rights management solution to protect its intellectual property. Which of the following should the company implement to enforce software digital rights?
A. Transport encryption
B. IPsec
C. Non-repudiation
D. Public key infrastructure
Answer: D
Explanation:
The Public-Key Infrastructure (PKI) is intended to offer a means of providing security to messages and transactions on a grand scale. The need for universal systems to support e-commerce, secure transactions, and information privacy is one aspect of the issues being addressed with PKI. A PKI can be used to protect software.
Q322. A security analyst performs the following activities: monitors security logs, installs surveillance cameras and analyzes trend reports. Which of the following job responsibilities is the analyst performing? (Select TWO).
A. Detect security incidents
B. Reduce attack surface of systems
C. Implement monitoring controls
D. Hardening network devices
E. Prevent unauthorized access
Answer: A,C
Explanation:
Q323. When Ann an employee returns to work and logs into her workstation she notices that, several desktop configuration settings have changed. Upon a review of the CCTV logs, it is determined that someone logged into Ann’s workstation. Which of the following could have prevented this from happening?
A. Password complexity policy
B. User access reviews
C. Shared account prohibition policy
D. User assigned permissions policy
Answer: A
Explanation:
The most important countermeasure against password crackers is to use long, complex passwords, which are changed regularly. Since changes were made to Ann’s desktop configuration settings while she was not at work, means that her password was compromised.
Q324. Which of the following allows a company to maintain access to encrypted resources when employee turnover is high?
A. Recovery agent
B. Certificate authority
C. Trust model
D. Key escrow
Answer: A
Explanation:
If an employee leaves and we need access to data he has encrypted, we can use the key recovery agent to retrieve his decryption key. We can use this recovered key to access the data. A key recovery agent is an entity that has the ability to recover a key, key components, or plaintext messages as needed. As opposed to escrow, recovery agents are typically used to access information that is encrypted with older keys.
Q325. Certificates are used for: (Select TWO).
A. Client authentication.
B. WEP encryption.
C. Access control lists.
D. Code signing.
E. Password hashing.
Answer: A,D
Explanation:
Certificates are used in PKI to digitally sign data, information, files, email, code, etc. Certificates are also used in PKI for client authentication.

Q326. A security technician at a small business is worried about the Layer 2 switches in the network suffering from a DoS style attack caused by staff incorrectly cabling network connections between switches.
Which of the following will BEST mitigate the risk if implemented on the switches?
A. Spanning tree
B. Flood guards
C. Access control lists
D. Syn flood
Answer: A
Explanation:
Spanning Tree is designed to eliminate network ‘loops’ from incorrect cabling between switches. Imagine two switches named switch 1 and switch 2 with two network cables connecting the switches. This would cause a network loop. A network loop between two switches can cause a ‘broadcast storm’ where a broadcast packet is sent out of all ports on switch 1 which includes two links to switch 2. The broadcast packet is then sent out of all ports on switch 2 which includes links back to switch 1. The broadcast packet will be sent out of all ports on switch 1 again which includes two links to switch 2 and so on thus flooding the network with broadcast traffic. The Spanning-Tree Protocol (STP) was created to overcome the problems of transparent bridging in redundant networks. The purpose of STP is to avoid and eliminate loops in the network by negotiating a loop-free path through a root bridge. This is done by determining where there are loops in the network and blocking links that are redundant. Spanning-Tree Protocol executes an algorithm called the Spanning-Tree Algorithm (STA). In order to find redundant links, STA will choose a reference point called a Root Bridge, and then determines all the available paths to that reference point. If it finds a redundant path, it chooses for the best path to forward and for all other redundant paths to block. This effectively severs the redundant links within the network. All switches participating in STP gather information on other switches in the network through an exchange of data messages. These messages are referred to as Bridge Protocol Data Units (BPDUs). The exchange of BPDUs in a switched environment will result in the election of a root switch for the stable spanning-tree network topology, election of designated switch for every switched segment, and the removal of loops in the switched network by placing redundant switch ports in a backup state.
Q327. Which of the following would Pete, a security administrator, MOST likely implement in order to allow employees to have secure remote access to certain internal network services such as file servers?
A. Packet filtering firewall
B. VPN gateway
C. Switch
D. Router
Answer: B
Explanation:
VPNs are usually employed to allow remote access users to connect to and access the network, and offer connectivity between two or more private networks or LANs. A VPN gateway (VPN router) is a connection point that connects two LANs via a nonsecure network such as the Internet.
Q328. An organization does not have adequate resources to administer its large infrastructure. A security administrator wishes to integrate the security controls of some of the network devices in the organization. Which of the following methods would BEST accomplish this goal?
A. Unified Threat Management
B. Virtual Private Network
C. Single sign on
D. Role-based management
Answer: A
Explanation:
Unified Threat Management (UTM) is, basically, the combination of a firewall with other abilities.
These abilities include intrusion prevention, antivirus, content filtering, etc. Advantages of
combining everything into one:
You only have one product to learn.
You only have to deal with a single vendor.
IT provides reduced complexity.
Q329. The server administrator has noticed that most servers have a lot of free disk space and low memory utilization. Which of the following statements will be correct if the server administrator migrates to a virtual server environment?
A. The administrator will need to deploy load balancing and clustering.
B. The administrator may spend more on licensing but less on hardware and equipment.
C. The administrator will not be able to add a test virtual environment in the data center.
D. Servers will encounter latency and lowered throughput issues.
Answer: B
Explanation:
Q330. A security administrator is concerned about the strength of user’s passwords. The company does not want to implement a password complexity policy. Which of the following can the security Administrator implement to mitigate the risk of an online password attack against users with weak passwords?
A. Increase the password length requirements
B. Increase the password history
C. Shorten the password expiration period
D. Decrease the account lockout time
Answer: C
Explanation:
Reducing the password expiration period will require passwords to be changed at the end of that period. A password needs to be changed if it doesn’t meet the compliance requirements of the company’s password policy, or is evidently insecure. It will also need to be changed if it has been reused, or due to possible compromise as a result of a system intrusion. This will give online password attackers less time to crack the weak passwords.
