Question 10

Due to an increase in wireless demand, 50 additional access points were installed as part of an expansion project. Each device was configured and managed separately, working with its own configuration. Which of the following network devices would assist the network team with reducing complexity and enforcing policies on the WLAN?
A) Wireless controller
B) Wireless range extender
C) Wireless load balancer
D) Wireless analyzer

Accepted Answer

A wireless controller helps manage multiple access points from a central location, reducing complexity and allowing for consistent policy enforcement across the WLAN.

Question 11

A network administrator is securing the wireless network in a multitenant building. The network uses a passphrase for authentication so it is easy to allow guests onto the wireless network, but management would like to prevent users from outside the office space from accessing the network. Which of the following security mechanisms would BEST meet this requirement?
A) MAC filtering
B) WPA-PSK
C) 802.1X
D) Geofencing

Accepted Answer

Geofencing can restrict network access based on physical location, preventing users outside the office space from connecting to the network.

Question 12

A network administrator needs to be able to burst datacenter capacity during peak times, but does not want to pay for on-premises hardware that is not used during off-peak times. Which of the following would aid in this scenario?
A) Public cloud
B) SaaS
C) PaaS
D) Hybrid cloud

Accepted Answer

The answer of A network administrator needs to be able...

Question 13

Which of the following is used to purposely attack a system to exploit vulnerabilities?
A) Honeypot
B) Vulnerability scan
C) Device hardening
D) Penetration testing

Accepted Answer

Penetration testing is a method used to simulate an attack on a system to identify and exploit vulnerabilities.

Question 14

A security administrator wants to implement the ability to prevent an authorized user from tailgating into the office building. Which of the following should be implemented?
A) Badge reader
B) Bluetooth reader
C) Cipher lock
D) Mantrap

Accepted Answer

A mantrap is a physical security mechanism designed to prevent tailgating by controlling access to a secure area through a two-door system, ensuring only one person can enter at a time.

Question 15

A technician restored network connectivity on a user's laptop. After validating full system functionality, which of the following steps should the technician take NEXT?
A) Duplicate the problem, if possible
B) Determine if anything has changed
C) Test the theory to determine the cause
D) Document the findings, actions, and outcomes

Accepted Answer

After resolving an issue and confirming that the system is functioning properly, the next step is to document the findings, actions taken, and outcomes to ensure there is a record for future reference and to help in similar situations.

Question 16

A network technician is responding to a user's trouble ticket. After replacing the network patch cable with a longer cable, the user is no longer connecting to the network. The network administrator tests the patch cable with a tester and confirms the cable is not faulty. Which of the following is the issue with the newly installed cable?
A) The user ordered Cat5e cable instead of Cat3.
B) A crossover cable was installed.
C) The total cable run exceeds the maximum distance.
D) There is a network speed mismatch between the computer and the switch.

Accepted Answer

The issue is likely that the total cable run exceeds the maximum distance for Ethernet cables, which is typically 100 meters for Cat5e/Cat6 cables. If the new cable is too long, it can cause connectivity issues.
