Sample Questions:

Question 1:
You are going to replace a power supply in a desktop computer. Which of the following actions should you take FIRST?

A. Use a grounding probe to discharge the power supply
B. Remove any jewelry you are wearing
C. Dispose of the old power supply
D. Verify proper cable management is being used

Correct Answer : B

Explanation
OBJ-4.4: Before working on a computer or server, you should always remove your jewelry. Jewelry such as bracelets and necklaces can often dangle and come into contact with sensitive components or electrical connections that can cause damage to the components or injure you. Therefore, all jewelry should be removed before working on an electrical system or computer to reduce the risk of shock. A grounding probe is not required to discharge the power supply since the technician should never be opening up the case of a power supply. The old power supply should be safely disposed of after it is removed, but it should not be removed until you have removed your jewelry. Proper cable management is important when installing a power supply, but again this should only occur after removing your jewelry.

Question 2:
What umask should be set for a directory to have 700 as its octal permissions?

A. r--r--r--
B. rwx---rwx
C. rwx------
D. Rwxrwxrwx

Correct Answer : C

Explanation
OBJ-2.6: RWX is 7 and --- is 0. In Linux, you can convert letter permissions to octal by giving 4 for each R, 2 for each W, and 1 for each X. R is for read-only, W is for write, and X is for execute. The permissions strings are written to represent the owner’s permissions, the group’s permissions, and the other user’s permissions.

Question 3:
Which of the following physical security controls would be the most effective in preventing an attacker from driving a vehicle through the glass doors at the front of the organization's headquarters?

A. Bollards
B. Intrusion alarm
C. Access control vestibule
D. Security guards

Correct Answer :

Explanation
OBJ-2.1: Bollards are a physical security control that is designed to prevent a vehicle-ramming attack. Bollards are typically designed as sturdy, short, vertical posts. Some organizations have installed more decorative bollards created out of cement and are large enough to plant flowers or trees inside. Access control vestibules are designed to prevent individuals from tailgating into the building. Security guards and intrusion alarms could detect this from occurring but not truly prevent them.

Question 4:
Which of the following tools should you utilize to ensure you don't damage a laptop's SSD while replacing it?

A. Air filter mask
B. Antistatic bag
C. ESD strap
D. Latex gloves

Correct Answer : C

Explanation
OBJ-4.4: The key to answering this question is the word "while" in the sentence. Since you need to protect the SSD "while" you are replacing it, you must ensure you wear an ESD strap. An ESD strap is placed around your wrist and dissipates any static electricity from your body to protect sensitive hardware such as processors, memory, expansion cards, and SSDs during installation. An electrostatic discharge (ESD) is the release of a charge from metal or plastic surfaces that occurs when a potential difference is formed between the charged object and an oppositely charged conductive object. This electrical discharge can damage silicon chips and computer components if they are exposed to it. An antistatic bag is a packaging material containing anti-ESD shielding or dissipative materials to protect components from ESD damage. An antistatic bag is a packaging material containing anti-ESD shielding or dissipative materials to protect components from ESD damage. An air filter mask is a mask manufactured from polyester sheets that cover your nose and mouth to prevent the dust from being breathed in by a technician. Latex gloves are hand coverings to protect the technician when they are working with toner or other chemicals.

Question 5:
You are working on upgrading the memory of a laptop. After removing the old memory chips from the laptop, where should you safely store them until you are ready to reuse them in another laptop?

A. Ziplock bags
B. Manila envelopes
C. Cardboard box
D. Antistatic bag

Correct Answer : D

Explanation
OBJ-4.4: To properly handle and store sensitive components, like a memory chip, you should use an ESD strap and place the components in an antistatic bag. An antistatic bag is a bag used for storing electronic components, which are prone to damage caused by electrostatic discharge (ESD). These bags are usually plastic polyethylene terephthalate (PET) and have a distinctive color (silvery for metalized film, pink or black for polyethylene).

Question 6:
Which type of authentication method is commonly used with physical access control systems and relies upon RFID devices embedded into a token?

A. Smart cards
B. HOTP
C. TOTP
D. Proximity cards

Correct Answer : D

Explanation
OBJ-2.1: A proximity card is a contactless card that usually utilizes RFID to communicate with the reader on a physical access system. These are commonly used to access secured rooms (such as server rooms) or even a building itself (such as at an access control vestibule). Some smart cards contain proximity cards within them, but the best answer to this question is proximity cards since that is the function of the smart card would be the device used to meet this scenario's requirements. An HMAC-based one-time password (HOTP) is a one-time password algorithm based on hash-based message authentication codes. A Time-based one-time password (TOTP) is a computer algorithm that generates a onetime password that uses the current time as a source of uniqueness.

Question 7:
You are formatting a 4 TB external hard drive on your MacBook.
The drive will be used to share files large video files between your MacBook and your friend's Windows 10 desktop.
Which file format should you use?

A. HFS
B. FAT32
C. NTFS
D. exFAT

Correct Answer : D

Explanation
OBJ-1.8: The only file system format that would work for this situation is exFAT. A macOS system can format a hard drive as APFS, HFS+, HFS, exFAT, or FAT32. The Windows system would only be able to read exFAT or FAT32. Unfortunately, FAT32 only supports drive sizes up to 32 GB, and file sizes up to 4 GB. Therefore, exFAT should be used as it supports sizes up to 128 petabytes.

Question 8:
Jason is out of town on a business trip and needs to access the share drive on his company's corporate network.
Which of the following types of network connections should he use to access the share drive from his hotel room?

A. Wireless
B. Dial-up
C. Wired
D. VPN

Correct Answer : D

Explanation
OBJ-1.6: The user must connect remotely through a VPN to access the company's shared drive and shared resources. The VPN connection is established over a wired, wireless, cellular, or dial-up connection, but Jason will not access the corporate resources without first authentication through the VPN. A virtual private network creates a secure tunnel between two endpoints connected via an insecure network such as the Internet. VPNs use encryption software is used to ensure the privacy of data as messages transit through the public network. VPNs also use authentication software to validate the user has permission to connect. Once connected to the VPN, the user will be able to access all of the resources on the local area network as if they were still located in their office.
