Question 1

Some users are reporting a high response time to access network resources after a new network router was installed. Which of the following documents should be updated every time a change is implemented on the network to have information about the metrics that represents how the network behaves during the normal scenarios?

Accepted Answer

The performance baseline should be updated to reflect the normal operating metrics of the network, allowing for comparison after changes are made to identify any deviations or issues.

Question 2

A corporation has been the target of hackers who exploited TCP port 80. The network administrator is tasked with securing connections to the web server. Which of the following protocols should be implemented to BEST secure the web server? (Choose two.)

Question 3

A technician is making the population of routers more secure. Which of the following are the BEST options for making authentication more secure? (Choose two.)

Accepted Answer

Disabling Telnet and implementing AAA (Authentication, Authorization, and Accounting) are the best options for making authentication more secure. Telnet is insecure because it transmits data in plaintext, while AAA provides a robust framework for managing user access and permissions.

Question 4

A small business utilizes a SOHO router and wishes to secure its existing wireless infrastructure. The business has fewer than ten devices, which are a mixture of old and new machines. Due to the varying ages of the machines, the latest wireless encryption methods may not be supported on all devices. Which of the following would be the MOST cost-effective method to add a layer of security while allowing all machines to connect?

Accepted Answer

The answer of A small business utilizes a SOHO router...

Question 5

While reviewing switch logs, a network analyst notices many failed logon attempts followed by a successful logon from an unknown IP address. Which of the following hardening techniques should be utilized to prevent unauthorized access?

Accepted Answer

Using strong, uncommon passwords can help prevent unauthorized access by making it more difficult for attackers to guess or crack passwords.

Question 6

Ann, a network technician, has relocated a rack that contains the networking and server equipment from the third floor to the sixth floor. To connect the rack-mounted router to the media converter in the first-floor MDF, she extended the length of the original 197ft (60m) Cat5e cable to 395ft (120m) by attaching another 197ft (60m) cable with an RJ45 coupler. After the move, users report intermittent connectivity to external websites, although connectivity to internal hosts has not changed. Which of the following is a network performance issue that is MOST likely causing this issue?

Accepted Answer

The extended cable length exceeds the maximum recommended length for Cat5e cables (100 meters), leading to signal attenuation and causing intermittent connectivity issues.

Question 7

Which of the following BEST describes the RADIUS authentication service protocol?

Accepted Answer

The answer of Which of the following BEST describes the...

Question 8

A company will be hosting a large workshop for local business leaders, and management wants to provide an easy-to-connect-to guest wireless network for them to access while on site. The network will be disabled after the workshop. The current wireless network has the option to enable a segmented guest network that has not been implemented. Which of the following authentication methods should be used to make the network EASIEST for guests to access?

Accepted Answer

An open network does not require any authentication, making it the easiest for guests to access without needing to enter a password or use any credentials.

Question 9

A network administrator needs to implement a new IP subnet containing 29 hosts. It is possible that the number of hosts in that subnet could eventually double. The company only has a single, unused public IP network left to work with: 164.10.12.0/24. Which of the following would be the BEST way to divide this network without wasting addresses?

Accepted Answer

A /26 subnet provides 62 usable addresses, which can accommodate the current 29 hosts and the potential doubling to 58 hosts, while minimizing wasted addresses.

Question 10

A technician is required to install a new DOCSIS-based Internet connection. Which of the following medium types does this use?

Accepted Answer

DOCSIS (Data Over Cable Service Interface Specification) is a standard used for transmitting internet data over cable television systems, which typically use RG-6 coaxial cable.

Question 11

A school is implementing a wireless network and wants to ensure there is adequate coverage. The gymnasium has thick cinder-block walls, and there are several offices adjacent to it. Which of the following should the network technician recommend to ensure full coverage while minimizing the total number of APs purchased?

Accepted Answer

Using a spectrum analyzer to generate a heat map will help determine the optimal placement of access points, ensuring full coverage with the minimum number of APs needed.

Question 12

A company deploys many workers in the field who remotely access files from a server at headquarters. Leadership is concerned about the risks posed when field workers update these files from unsecured networks. Which of the following policy changes can the company make to MOST improve the confidentiality of connections when connecting remotely? (Choose two.)

Accepted Answer

Implementing SSL VPN connections ensures encrypted communication, protecting data confidentiality. Utilizing HTTPS for intranet access also encrypts data, enhancing security over unsecured networks.

Question 13

A home user has contacted the help desk to transfer files from an old smartphone to a new one. The help desk analyst informs the home user this can be completed using Bluetooth. Which of the following types of topologies is this called?

Accepted Answer

Bluetooth is typically used for short-range communication between devices, which is characteristic of a Personal Area Network (PAN).

Question 14

A company needs a secure way to provide building blueprints to an engineering partner frequently. The Chief Information Officer (CIO) states that a secure protocol must be used for transfer, and the partner needs to initiate a secure connection to the company's router. Which of the following would BEST meet the requirements? (Choose two.)

Accepted Answer

A Client-to-site VPN allows the partner to securely connect to the company's network, and SFTP provides a secure protocol for transferring files like blueprints.

Question 15

Which of the following allows for file-level network storage?

Accepted Answer

NAS (Network Attached Storage) allows for file-level network storage, providing access to files over a network.

Question 16

A security administrator wants to implement the ability to prevent an unauthorized user from tailgating into the office building. Which of the following should be implemented?

Accepted Answer

A mantrap is a physical security mechanism designed to prevent unauthorized access by controlling the entry and exit of individuals, effectively preventing tailgating.

Question 17

A technician purchasing equipment for a company has determined that several new employees will require new wired workstations. Which of the following is the network technician likely to recommend to add the employees to the existing infrastructure?

Accepted Answer

A switch is the most appropriate device to connect multiple wired devices in a network, allowing the new employees' workstations to communicate with the existing infrastructure efficiently.

Question 18

Joe, a technician, was able to copy data at a site with no network equipment between two new laptops, featuring gigabit Ethernet ports, by using a regular straight-through patch cable. Joe then unsuccessfully tried to accomplish the same thing at a different site from his laptop with a gigabit Ethernet port to an older customer unit, which had a 10/100 network port. Which of the following is the cause of this?

Accepted Answer

The customer's laptop does not support auto-MDIX, which is necessary for automatically switching between straight-through and crossover cable configurations. Older 10/100 network ports often lack this feature, requiring a crossover cable for direct connections.
