QUESTION 551
Which of the following can be used to maintain a higher level of security in a SAN by allowing isolation of mis-configurations or faults?
A. VLAN
B. Protocol security
C. Port security
D. VSAN
Answer: D
Explanation:
A storage area network (SAN) is a secondary network that offers storage isolation by consolidating storage devices such as hard drives, drive arrays, optical jukeboxes, and tape libraries. Virtualization can be used to further enhance the security of a SAN by using switches to create a VSAN. These switches act as routers controlling and filtering traffic into and out of the VSAN while allowing unrestricted traffic within the VSAN.
QUESTION 552
A company needs to receive data that contains personally identifiable information. The company requires both the transmission and data at rest to be encrypted. Which of the following achieves this goal? (Select TWO).
A. SSH
B. TFTP
C. NTLM
D. TKIP
E. SMTP
F. PGP/GPG
Answer: AF
Explanation:
We can use SSH to encrypt the transmission and PGP/GPG to encrypt the data at rest (on disk).
A: Secure Shell (SSH) is a cryptographic protocol that can be used to secure network communication. It establishes a secure tunnel over an insecure network.
F: Pretty Good Privacy (PGP) is a data encryption and decryption solution that can be used for signing, encrypting, and decrypting texts, e-mails, files, directories, and whole disk partitions and to increase the security of e-mail communications.
QUESTION 553
Which of the following does full disk encryption prevent?
A. Client side attacks
B. Clear text access
C. Database theft
D. Network-based attacks
Answer: B
Explanation:
Full-disk encryption encrypts the data on the device. This feature ensures that the data on the device cannot be accessed in a useable form should the device be stolen.
QUESTION 554
Full disk encryption is MOST effective against which of the following threats?
A. Denial of service by data destruction
B. Eavesdropping emanations
C. Malicious code
D. Theft of hardware
Answer: D
Explanation:
Full-disk encryption encrypts the data on the device. This feature ensures that the data on the device cannot be accessed in a useable form should the device be stolen. However, it does not prevent the theft of hardware it only protects data should the device be stolen.
QUESTION 555
Which of the following is the BEST method for ensuring all files and folders are encrypted on all corporate laptops where the file structures are unknown?
A. Folder encryption
B. File encryption
C. Whole disk encryption
D. Steganography
Answer: C
Explanation:
Full-disk encryption encrypts the data on the hard drive of the device or on a removable drive. This feature ensures that the data on the device or removable drive cannot be accessed in a useable form should it be stolen. Furthermore, full-disk encryption is not dependant on knowledge of the file structure.
QUESTION 556
To protect corporate data on removable media, a security policy should mandate that all removable devices use which of the following?
A. Full disk encryption
B. Application isolation
C. Digital rights management
D. Data execution prevention
Answer: A
Explanation:
Full-disk encryption encrypts the data on the hard drive of the device or on a removable drive. This feature ensures that the data on the device or removable drive cannot be accessed in a useable form should it be stolen.
QUESTION 557
A merchant acquirer has the need to store credit card numbers in a transactional database in a high performance environment. Which of the following BEST protects the credit card data?
A. Database field encryption
B. File-level encryption
C. Data loss prevention system
D. Full disk encryption
Answer: A
Explanation:
Database encryption makes use of cryptography functions that are built into the database software to encrypt the data stored in the data base. This often offers granular encryption options which allows for the encryptions of the entire database, specific database tables, or specific database fields, such as a credit card number field.
QUESTION 558
Which of the following types of data encryption would Matt, a security administrator, use to encrypt a specific table?
A. Full disk
B. Individual files
C. Database
D. Removable media
Answer: C
Explanation:
A table is stored in a database. Database encryption makes use of cryptography functions that are built into the database software to encrypt the data stored in the database. This often offers granular encryption options which allows for the encryptions of the entire database, specific database tables, or specific database fields, such as a credit card number field.
QUESTION 559
A database administrator would like to start encrypting database exports stored on the SAN, but the storage administrator warns that this may drastically increase the amount of disk space used by the exports. Which of the following explains the reason for the increase in disk space usage?
A. Deduplication is not compatible with encryption
B. The exports are being stored on smaller SAS drives
C. Encrypted files are much larger than unencrypted files
D. The SAN already uses encryption at rest
Answer: C
Explanation:
Encryption adds overhead to the data which results in and increase in file size. This overhead is attached to each file and could include the encryption/decryption key, data recovery files and data decryption field in file header. As a result, requires increased storage space.
QUESTION 560
Which of the following is an advantage of implementing individual file encryption on a hard drive which already deploys full disk encryption?
A. Reduces processing overhead required to access the encrypted files
B. Double encryption causes the individually encrypted files to partially lose their properties
C. Individually encrypted files will remain encrypted when copied to external media
D. File level access control only apply to individually encrypted files in a fully encrypted drive
Answer: C
Explanation:
With full disk encryption a file is encrypted as long as it remains on the disk. This is because the data on the disk is decrypted when the user logs on, thus the data is in a decrypted form when it is copied to another disk. Individually encrypted files on the other hand remain encrypted.
QUESTION 561
A team of firewall administrators have access to a `master password list’ containing service account passwords. Which of the following BEST protects the master password list?
A. File encryption
B. Password hashing
C. USB encryption
D. Full disk encryption
Answer: A
Explanation:
File encryption can be used to protect the contents of individual files. It uses randomly generated symmetric encryption keys for the file and stores the key in an encrypted form using the user’s public key on the encrypted file.
QUESTION 562
A security administrator has concerns regarding employees saving data on company provided mobile devices. Which of the following would BEST address the administrator’s concerns?
A. Install a mobile application that tracks read and write functions on the device.
B. Create a company policy prohibiting the use of mobile devices for personal use.
C. Enable GPS functionality to track the location of the mobile devices.
D. Configure the devices so that removable media use is disabled.
Answer: D
Explanation:
Mobile devices can be plugged into computers where they appear as an additional disk in the same way as a USB drive. This is known as removable media. This would enable users to copy company data onto the mobile devices. By disabling removable media use, the users will not be able to copy data onto the mobile devices.
QUESTION 563
Which of the following can be used to mitigate risk if a mobile device is lost?
A. Cable lock
B. Transport encryption
C. Voice encryption
D. Strong passwords
Answer: D
Explanation:
Passwords are the most likely mechanism that can be used to mitigate risk when a mobile device is lost. A strong password would be more difficult to crack.
QUESTION 564
Which of the following types of encryption will help in protecting files on a PED?
A. Mobile device encryption
B. Transport layer encryption
C. Encrypted hidden container
D. Database encryption
Answer: A
Explanation:
Device encryption encrypts the data on a Personal Electronic Device (PED). This feature ensures that the data on the device cannot be accessed in a useable form should the device be stolen.
QUESTION 565
Which of the following is a way to implement a technical control to mitigate data loss in case of a mobile device theft?
A. Disk encryption
B. Encryption policy
C. Solid state drive
D. Mobile device policy
Answer: A
Explanation:
Disk and device encryption encrypts the data on the device. This feature ensures that the data on the device cannot be accessed in a useable form should the device be stolen.
QUESTION 566

QUESTION 567
Which of the following has a storage root key?
A. HSM
B. EFS
C. TPM
