• Question 1061:

  A technician is planning a network wiring installation and must ensure all cabling meets the installation requirements for air-handling spaces in the celling in case of a fire. Which of the following characteristics does plenum cabling have to meet this requirement?

  A. Outer jacket made of PVC
  B. Outer jacket with metal shielding
  C. Low-smoke material jacket
  D. Fiber-optic glass core
  C. Low-smoke material jacket

• Question 1062:

  The following DHCP scope was configured for a new VLAN dedicated to a large deployment of 325 loT sensors:

  

  The first 244 loT sensors were able to connect to the TFTP server, download the configuration file, and register to an loT management system. The other sensors are being shown as offline. Which of the following should be performed to determine the MOST likely cause of the partial deployment of the sensors?

  A. Check the gateway connectivity to the TFTP server.
  B. Check the DHCP network scope.
  C. Check whether the NTP server is online.
  D. Check the loT devices for a hardware failure.
  B. Check the DHCP network scope.

  Explanation/Reference:

  Since the CIDR is /24, there are 256 available IPs. The first IP would be for the gateway, and the last IP for the broadcast address, leaving you with 254 available IPs. Since the exclusion range is from 10.10.0.1 - 10, remove 10 available IPs and you're left with 244.

• Question 1063:

  A network administrator has discovered a low-end managed switch connoted to the company LAN. While reading about the device's specifications on the manufacturer's website, the administrator discovers the switch does not support a command line interface for administration. Which of the following remote access methods should the administrator use to log in the switch?

  A. install a VNC plugin on the web Browser
  B. Connect to the HTTPS management interface
  C. Replace the managed switch with an unmanaged switch.
  D. Establish an SSH session.
  B. Connect to the HTTPS management interface

• Question 1064:

  A network administrator is adding a new switch to the network. Which of the following network hardening techniques would be BEST to use once the switch is in production?

  A. Disable unneeded ports
  B. Disable SSH service
  C. Disable MAC filtering
  D. Disable port security
  A. Disable unneeded ports

  Explanation/Reference:

  Disabling unused ports can stop a bad guy from plugging a malicious device into an unused port and getting unauthorized access to the network. It can also help train users-especially those in remote offices-to call IT before moving things around. After a few go-rounds of plugging a computer into an empty port and having it not work, most people will take the hint that they need to call IT first.

• Question 1065:

  An attacker is attempting to find the password to a network by inputting common words and phrases in plaintext to the password prompt. Which of the following attack types BEST describes this action?

  A. Pass-the-hash attack
  B. Rainbow table attack
  C. Brute-force attack
  D. Dictionary attack
  D. Dictionary attack

  ---

  Explanation/Reference:

  -

  A pass-the-hash attack is a type of attack in which an attacker steals a user's password hash and uses it to gain unauthorised access to systems and resources.

  -

  A rainbow table attack is a type of password cracking method that uses pre-computed hashes to quickly crack encrypted passwords without brute-force guessing.

  -

  A brute-force attack is a method of guessing a password by systematically trying every possible combination of characters until the correct one is found.

  -

  A dictionary attack is a method of guessing a password by systematically trying words found in a dictionary or other word list until the correct password is found.

• Question 1066:

  Which of the following DHCP settings would be used to ensure a device gets the same IP address each time it is connected to the network?

  A. Scope options
  B. Reservation
  C. Exclusion
  D. Relay
  E. Pool
  A. Scope options

• Question 1067:

  Which of the following layers of the OSI model receives data from the application layer and converts it into syntax that is readable by other devices on the network?

  A. Layer 1
  B. Layer 3
  C. Layer 6
  D. Layer 7
  C. Layer 6

  ---

  Explanation/Reference:

  "Presentation Layer is the 6th layer in the Open System Interconnection (OSI) model. This layer is also known as Translation layer, as this layer serves as a data translator for the network. The data which this layer receives from the Application Layer is extracted and manipulated here as per the required format to transmit over the network. The main responsibility of this layer is to provide or define the data format and encryption. The presentation layer is also called as Syntax layer since it is responsible for maintaining the proper syntax of the data which it either receives or transmits to other layer(s)."

• Question 1068:

  Which of the following would be the MOST cost-effective recovery solution for a company's lower-priority applications?

  A. Warm site
  B. Cloud site
  C. Hot site
  D. Cold site
  B. Cloud site

• Question 1069:

  A technician recently installed a new wireless access point for a SOHO with the latest wireless technologies After the installation users with older laptops report their laptops no longer show the wireless network SSID, whereas users with newer equipment do not have this issue. Which of the following is MOST likely the cause?

  A. The passphrase was changed
  B. The wireless cards do not support 802 11ac.
  C. The security type has been upgraded to WPA2
  D. The administrator is not broadcasting the SSID
  B. The wireless cards do not support 802 11ac.

• Question 1070:

  A network administrator is decommissioning a server. Which of the following will the network administrator MOST likely consult?

  A. Onboarding and off boarding policies
  B. Business continuity plan
  C. Password requirements
  D. Change management documentation
  D. Change management documentation

  ---

  Explanation/Reference:

  When decommissioning a server, it is important to follow proper change management procedures to ensure that the process is documented and executed correctly. The change management documentation will typically outline the steps that should be followed when decommissioning a server, including any required approvals, notifications, or testing procedures.
