NEW QUESTION # 75
Which of the following should an installer orient a port-side exhaust to when installing equipment?
Answer: C
Explanation:
In data centers, hot aisle/cold aisle configurations are used to manage airflow and cooling efficiency. Port-side exhausts should be oriented towards the warm aisle to expel hot air and maintain optimal cooling. The document clarifies:
"Equipment with port-side exhausts should be oriented towards the warm aisle to ensure that hot air is properly directed away from the cold air intake areas. This alignment supports effective cooling in data center environments."

NEW QUESTION # 77
A company recently converted most of the office laptops to connect wirelessly to the corporate network. After a high-traffic malware attack, narrowing the event to a specific user was difficult because of the wireless configuration.
Which of the following actions should the company take?
Answer: A
Explanation:
Using Pre-Shared Key (PSK) authentication means that all users share the same Wi-Fi password, making it difficult to identify individual users when security incidents occur.
Migrating to WPA2-Enterprise (or WPA3-Enterprise) replaces PSK authentication with individual user credentials using 802.1X authentication and a RADIUS server. This allows the organization to:
Track and log specific user activity
Enforce per-user authentication policies
Improve network security
Breakdown of Options:
A . Restrict users to the 5GHz frequency - Improves performance but does not enhance user tracking or security.
B . Upgrade to a mesh network - A mesh network improves coverage, not security tracking.
C . Migrate from PSK to Enterprise - โ
Correct answer. WPA2-Enterprise or WPA3-Enterprise uses individual user authentication, allowing per-user tracking.
D . Implement WPA2 encryption - WPA2 is already widely used; it does not resolve the tracking issue.

NEW QUESTION # 78
Which of the following terms describes the capability in a public cloud to add or remove compute resources based on need?
Answer: B
Explanation:
The correct answer is C. Elasticity . In cloud computing, elasticity refers to the ability to increase or decrease resources quickly based on current demand . If workloads rise, more compute resources can be allocated. If demand drops, those resources can be reduced again. That is exactly what the question is describing.
This is slightly different from scalability . Scalability is the broader idea that a system can grow to handle more workload. Elasticity focuses more on the dynamic, on-demand adjustment of resources as conditions change. In exam questions, wording like "add or remove based on need" usually points straight to elasticity.
The other answer choices do not fit. Availability is about uptime and service access. Multitenancy refers to multiple customers sharing underlying cloud infrastructure while remaining logically separated. Neither describes rapid expansion and contraction of compute resources.
From a Network+ study perspective, elasticity is one of the core cloud characteristics to remember because it explains why cloud services are useful for workloads that are unpredictable or variable. Instead of permanently building for peak demand, organizations can consume more or less compute as required. That makes elasticity the best answer.
