Question 11

A company is experiencing Wi-Fi performance issues. Three Wi-Fi networks are available, each running on the 2.4 GHz band and on the same channel. Connecting to each Wi-Fi network yields slow performance. Which of the following channels should the networks be configured to?

A. Channel 1, Channel 2. and Channel 3
B. Channel 2. Channel 4, and Channel 9
C. Channel 1, Channel 6, and Channel 11
D. Channel 3, Channel 5, and Channel 10

Correct Answer:C
These are the three non-overlapping channels in the 2.4 GHz band, eliminating co-channel and adjacent-channel interference for optimal Wi-Fi performance.

Question 12

A network administrator is configuring firewall rules to lock down the network from outside attacks. Which of the following should the administrator configure to create the most strict set of rules?

A. URL filtering
B. File blocking
C. Network security group
D. Allow List

Correct Answer:D
By explicitly permitting only known, approved traffic and blocking everything else by default, an allow-list policy enforces the strictest firewall posture.

Question 13

A company is experiencing numerous network issues and decides to expand its support team. The new junior employees will need to be onboarded in the shortest time possible and be able to troubleshoot issues with minimal assistance. Which of the following should the company create to achieve this goal?

A. Statement of work documenting what each junior employee should do when troubleshooting
B. Clearly documented runbooks for networking issues and knowledge base articles
C. Physical and logical network diagrams of the entire networking infrastructure
D. A mentor program for guiding each junior employee until they are familiar with the networking infrastructure

Correct Answer:B
Runbooks provide step-by-step troubleshooting procedures, and a solid knowledge base captures known issues and resolutions. Together they let new team members ramp up quickly and resolve common network problems with minimal hand-holding.

Question 15

A network engineer is setting up guest access on a Wi-Fi network. After a recent network analysis, the engineer discovered that a user could access the guest network and attack the corporate network, since the networks share the same VLAN. Which of the following should the engineer do to prevent an attack like this one from happening?

A. Configure Layer 2 client isolation for the wireless network.
B. Set up a MAC filtering rule and add the MAC addresses of all corporate devices to the allow list.
C. Set up a strong password on the guest wireless network.
D. Set up a captive portal so all guest users have to register before gaining access to the wireless network.

Correct Answer:A
By enabling client isolation at Layer 2, guest clients can still reach the Internet but cannot directly communicate with any other device on that VLAN, including your corporate endpoints, stopping lateral attacks without needing MAC whitelists or overly complex captive-portal setups.
