A network administrator needs to connect to resources from an offsite location while ensuring the traffic is protected. Which of the following should the administrator use to gain access to the secure network?
- A.
SSH
- B.
VPN
- C.
SFTP
- D.
RDP
Correct Answer
B. VPNExplanation
A network administrator should use a VPN (Virtual Private Network) to gain access to the secure network from an offsite location while ensuring the traffic is protected. VPN creates a secure and encrypted connection over a public network, such as the internet, allowing the administrator to access resources securely and privately. It provides authentication, confidentiality, and integrity of the data transmitted between the administrator's device and the secure network. SSH (Secure Shell) is a network protocol used for secure remote access, SFTP (Secure File Transfer Protocol) is used for secure file transfer, and RDP (Remote Desktop Protocol) is used for remote desktop access, but they do not provide the same level of security and protection as a VPN.Rate this question:

A user states that when typing in directions on a navigation website, the map is not viewable in a newer web browser. The technician runs updates to Java, but is still unable to view the map. The technician should change which of the following Internet Options?
- A.
Compatibility view
- B.
Manage add-ons
- C.
Clear browser cache
- D.
Pop-up blocker
Correct Answer
A. Compatibility viewExplanation
The technician should change the "Compatibility view" Internet Option.

A company that manages its own cloud, while utilizing a third-party vendor to help manage storage, is implementing which of the following infrastructure types?
- A.
Hybrid
- B.
Community
- C.
Private
- D.
Public
Correct Answer
A. HybridExplanation
A company that manages its own cloud infrastructure but also utilizes a third-party vendor to help manage storage is implementing a hybrid infrastructure. A hybrid infrastructure combines elements of both private and public cloud environments. In this case, the company has its own private cloud for managing most of its computing resources, but it leverages a third-party vendor's public cloud storage services to offload and manage storage needs. This allows the company to have more control over its sensitive data and applications while also taking advantage of the scalability and cost-effectiveness of public cloud storage.Rate this question:

Which of the following features of a mobile device operates the touch screen?
- A.
Gyroscope
- B.
Digitizer
- C.
Accelerometer
- D.
Geotracking
Correct Answer
B. DigitizerExplanation

A technician has been tasked with limiting the users who can connect to a network printer located centrally within an office environment. Which of the following tools would be the BEST to utilize to achieve this goal?
- A.
VPN
- B.
ACL
- C.
RDP
- D.

ACL stands for Access Control List, which is a tool used to control access to network resources. In this scenario, the technician wants to limit the users who can connect to a network printer. By implementing an ACL, the technician can specify which users or groups are allowed or denied access to the printer. This ensures that only authorized users can connect to the printer, increasing security and preventing unauthorized access. VPN (Virtual Private Network) is used to establish a secure connection over a public network, RDP (Remote Desktop Protocol) is used to remotely access and control a computer, and DLP (Data Loss Prevention) is a system used to prevent the unauthorized transmission of sensitive data.Rate this question:

- B.
Require multifactor authentication to log into laptop.
- C.
Require laptop hard drives to be encrypted.
- D.
Require users to change their password at frequent intervals.
- E.
Require users to have strong passwords.
Correct Answer
C. Require laptop hard drives to be encrypted.Explanation
The first step in implementing a best practice security policy after a lost laptop with sensitive corporate information has been published on the Internet is to require laptop hard drives to be encrypted. Encrypting the hard drives ensures that even if the laptop falls into the wrong hands, the data cannot be accessed without the encryption key. This helps to protect the sensitive information and prevent unauthorized access.Rate this question:

A technician is attempting to manually migrate a user’s profile from one Windows PC to another. Files in the user’s My Documents folder cannot be copied. Some files in question have green letters in the filenames. Which of the following file systems is causing this to occur?
- A.
ExFAT
- B.
COMPRESSED
- C.
EFS
- D.
NTFS
Correct Answer
C. EFSExplanation
The correct answer is EFS. EFS (Encrypting File System) is a feature in NTFS (New Technology File System) that allows users to encrypt files and folders to protect sensitive data. When files are encrypted using EFS, the filenames appear in green color. Therefore, if the technician is unable to copy files with green letters in the filenames, it indicates that those files are encrypted using EFS.Rate this question:

When securing a mobile device, which of the following types of screen locks is the MOST secure?
- A.
Fingerprint lock
- B.
Swipe lock
- C.
Passcode lock
- D.
Face lock
Correct Answer
A. Fingerprint lockExplanation
The most secure type of screen lock for a mobile device is the fingerprint lock. This is because fingerprints are unique to each individual, making it difficult for someone else to unlock the device without the owner's fingerprint. Additionally, fingerprints are not easily replicated or guessed, providing an extra layer of security compared to other types of screen locks such as swipe, passcode, or face lock.Rate this question:

A technician has upgraded four computers and would like to securely repurpose the hard drives for later use. Which of the following should the technician do to the drives to prepare them for later use?
- A.
Chkdsk
- B.
Degauss
- C.
Quick format
- D.
Drive wipe
Correct Answer
D. Drive wipeExplanation
To securely repurpose the hard drives for later use, the technician should perform a drive wipe. This process involves completely erasing all data on the hard drives, ensuring that no sensitive information remains. Unlike a quick format or chkdsk, which only perform surface-level checks or delete file system information, a drive wipe ensures that the data cannot be recovered. Degaussing, on the other hand, is a method used for erasing data from magnetic media such as tapes or floppy disks, and is not applicable to hard drives.Rate this question:
