Question 1

A network technician notices that switches of the same model have different commands and security features while administering them. Which of the following hardening techniques should the technician perform on a regular schedule to ensure all switches have the same features and security functionality?

Accepted Answer

Regularly applying patches and updates ensures that all switches have the latest features and security functionality, maintaining consistency across devices.

Question 2

A company's web-based application has a database that is set up for high availability in case of a failure. Which of the following is necessary to achieve this type of setup?

Accepted Answer

A virtual IP pointing to the active DB is necessary for high availability, as it allows seamless failover by redirecting traffic to the active database instance without requiring changes to the application or client configurations.

Question 3

An attacker has inserted a hub into a trunk link on the local network in an attempt to access the management subnet to attack the networking devices. Which of the following attacks can be used on a trunk link to provide access to the management subnet?

Accepted Answer

VLAN hopping is an attack method that can be used on a trunk link to gain unauthorized access to different VLANs, including the management subnet, by exploiting the VLAN tagging process.

Question 4

A network technician is performing an initial configuration of a new network switch. Per company policy, the only authorized manner for remotely administering the switch is through a command line. Which of the following protocols should the technician disable to adhere to the company policy?

Accepted Answer

HTTP is used for web-based management interfaces, which is not command line-based. Disabling HTTP ensures that remote administration is done only through command line protocols like SSH.

Question 5

Which of the following additional capabilities does a next generation firewall provide beyond a standard network firewall? (Choose two.)

Accepted Answer

Next generation firewalls offer advanced features like application control and user identification, which go beyond the basic packet filtering and stateful inspection of standard network firewalls.

Question 6

Management at a company wants to increase the bandwidth available to users after receiving several complaints. A technician reports to management that 50% of the company bandwidth is being utilized by wireless devices outside the company's property. Given budget constraints, which of the following solutions should the technician propose to management?

Accepted Answer

Configuring geofencing can help restrict the wireless network's access to a specific geographic area, preventing unauthorized devices outside the company's property from using the bandwidth.

Question 7

A user in the marketing department reports the email server is down. The user has not received email for more than 24 hours. Which of the following should the network technician do to investigate this issue?

Accepted Answer

The technician should first determine if the issue is isolated to one user or affecting multiple users by questioning others in the marketing department. This helps identify if the problem is with the user's setup or a broader issue with the email server.

Question 8

A technician needs to connect two routers using copper cables. Which of the following cables would utilize both the TIA/EIA 568a and TIA/EIA 568b standards?

Accepted Answer

A Cat5 crossover cable uses both the TIA/EIA 568a and TIA/EIA 568b standards, with one end wired as 568a and the other as 568b, allowing for direct device-to-device connections like between two routers.

Question 9

A network technician has installed multiple new lightweight access points across the network. Which of the following devices should the technician use to manage the new access points?

Accepted Answer

A wireless controller is used to manage multiple lightweight access points in a network, allowing centralized management and configuration.

Question 10

A user does not have access to network services but has Internet access. The technician notices the computer has an IP address of 192.168.1.144 when the network is 10.10.10.0. Which of the following is MOST likely the issue?

Accepted Answer

The IP address 192.168.1.144 indicates that the computer is receiving an IP address from a different network, suggesting the presence of a rogue DHCP server assigning incorrect IP addresses.

Question 11

Which of the following policies would be the MOST useful for defining the proper procedures when an employee is terminated abruptly?

Accepted Answer

Offboarding policies are specifically designed to handle the procedures and processes involved when an employee leaves an organization, including abrupt terminations.

Question 12

A technician is trying to identify the cause of an issue several wireless users are experiencing at an office. The office is in a square-shaped building, with four 802.11b WAPs with omnidirectional antennas located in the four corners of the building. Users near the center of the building report sporadic issues connecting to resources. The technician checks the signal strength in the middle of the building and determines it is adequate. Which of the following is causing the reported issue?

Accepted Answer

There is likely channel overlap between the access points, causing interference and connectivity issues for users in the center of the building.

Question 13

A network technician is setting up a new web server on the company network. One of the requirements for the web server is to ensure the end users can securely authenticate to the application to perform their job duties. Which of the following ports should the network technician request from the firewall team to comply with this requirement?

Accepted Answer

Port 443 is used for HTTPS, which provides secure communication over the internet, ensuring that end users can securely authenticate to the web application.

Question 14

To increase speed and availability, a high-traffic web application was split into three servers recently and moved behind a load balancer. Which of the following should be configured on the load balancer to allow for a single destination?

Accepted Answer

A Virtual IP (VIP) is used in load balancing to allow multiple servers to appear as a single destination IP address, distributing traffic among them.

Question 15

A network team at a large company has received funding for a WiFi refresh. One of the requirements in the RFP is the new WLAN infrastructure must provide APs that support multiple streams of information at the same time. For which of the following WiFi features is the network team looking?

Accepted Answer

MU-MIMO (Multi-User Multiple Input Multiple Output) allows multiple devices to receive data simultaneously from a single access point, supporting multiple streams of information at the same time.

Question 16

Management is concerned there is excessive traffic on the network. A network technician wants to run a quick port scan to see any systems that have open ports. Which of the following tools should be used to do this?

Accepted Answer

Nmap is a tool specifically designed for network discovery and security auditing, including scanning for open ports on systems.

Question 17

A company's server-naming convention is overly complicated. The systems administrator wants to change the naming convention to make it easier for users to remember which hosts they should log into. However, renaming servers is complicated and requires some downtime. Which of the following DNS record types would accomplish this goal without requiring servers to be renamed?

Accepted Answer

A CNAME (Canonical Name) record allows you to create an alias for a domain name, pointing it to another domain name. This means users can use an easier-to-remember alias without changing the actual server names.

Question 18

Which of the following protocols is used to transport outgoing mail across networks?

Accepted Answer

SMTP (Simple Mail Transfer Protocol) is used to transport outgoing mail across networks.

Question 19

After deployment of a second network link to load balance the network traffic, the quality of voice calls degrades. The network administrator discovers the voice packets are arriving at uneven intervals that cannot be handled by the voice application buffer. Which of the following actions will improve the quality of the voice calls?

Accepted Answer

Controlling the jitter, which is the variation in packet arrival times, will help ensure that voice packets arrive at regular intervals, improving the quality of voice calls.
