Early in the morning, an administrator installs a new DHCP server. In the afternoon, some users report they are experiencing network outages. Which of the following is the most likely issue?
Answer: A
A. The administrator did not provision enough IP addresses. When a new DHCP server is installed, it is responsible for dynamically assigning IP addresses to clients on the network. If the administrator did not provision enough IP addresses (by setting an appropriately sized IP address pool), clients may not be able to obtain IP addresses, leading to network outages or connectivity issues.

A company is implementing a policy that will not allow employees to bring personal devices to the office and connect to the wireless network. Which of the following is the best way to enforce this policy?
Answer: B
A network engineer is troubleshooting an issue with a VoIP network. After performing analysis, the engineer found that when users upload large files, voice quality is severely degraded. When no other traffic is on the network, voice quality is fine. Which of the following should the engineer do to most likely resolve the issue?
Answer: C
C. Configure QoS on the router. Explanation: Quality of Service (QoS) is used to prioritize certain types of traffic over others on a network. In this case, the issue is that voice quality is degraded when users upload large files, likely because file uploads consume a significant amount of bandwidth, causing congestion and affecting the real-time nature of VoIP traffic

A network administrator needs to improve network monitoring. Which of the following should the administrator do first?
Answer: A
A. Establish baseline metrics. Explanation: Establishing baseline metrics is the first step in improving network monitoring. A baseline represents the normal operating performance of the network, such as traffic patterns, bandwidth usage, and response times. By understanding what "normal" looks like, the administrator can more easily identify anomalies or performance issues when monitoring the network in the future.

A network administrator is troubleshooting issues with a DHCP server at a university. More students have recently arrived on campus, and the users are unable to obtain an IP address. Which of the following should the administrator do to address the issue?
Answer: C
C. Increase the scope size. Explanation: The issue is likely related to a shortage of available IP addresses in the DHCP scope. As more students arrive on campus, the demand for IP addresses increases. If the DHCP server’s scope (the range of IP addresses it can assign) is too small to accommodate all the devices, the server will not be able to assign IP addresses to new users. Increasing the DHCP scope size will allow the server to allocate more IP addresses, resolving the issue.

Which of the following is designed to distribute network traffic among devices based on the quantity of traffic?
Answer: A

A user recently moved a workstation to a different part of the office. The user is able to access the internet and print but is unable to access server resources. Which of the following is the most likely cause of the issue?
Answer: B
B. Wrong VLAN assignment Here’s why: The user can access the internet (which likely requires external routing via a gateway) and can print (which could be local or via a networked printer in the same VLAN), but is unable to access server resources. This suggests the user has network connectivity but is possibly on the wrong VLAN. Server resources are often restricted to specific VLANs, so if the user was moved to a port associated with a different VLAN, their device may no longer be able to reach the servers, especially if those resources are in a separate VLAN or subnet.
