Internal users are reporting high latency when connecting to external servers in the cloud. Which of the following should a network administrator optimize?

1. WAN

2. SAN

3. VLAN

4. LAN

The correct answer is: WAN

Optimizing the Wide Area Network (WAN) is crucial in the scenario where internal users are experiencing high latency when connecting to external servers in the cloud. The WAN encompasses the connections that link different geographical locations and allows for communication between local area networks (LANs) that are separated by significant distances. When users connect to external servers, the performance of the WAN plays a vital role in determining the speed and efficiency of those connections. High latency can stem from various factors related to WAN performance, such as bandwidth limitations, poor routing, or network congestion affecting the long-distance paths data must travel. By focusing on optimizing the WAN, such as improving bandwidth capacity or implementing efficient routing protocols, the network administrator can significantly decrease latency issues and enhance overall connectivity to external cloud resources. In contrast, other network components like the Storage Area Network (SAN), Virtual Local Area Network (VLAN), and Local Area Network (LAN) primarily deal with data storage, segmentation of network traffic, or local traffic within a confined geographic area. While optimizing these networks can improve local connectivity and performance for internal operations, they do not address the specific performance issues relating to connections made to external servers across the WAN. Hence, targeting WAN optimization is the most pertinent approach to resolve the high latency
