Post-WLAN Controller Deployment Tasks

The question asks for two additional tasks to consider after deploying a new WLAN controller (WLC). To determine the correct answers, we must look at the operational requirements of a Cisco wireless infrastructure as defined in the 200-301 exam objectives.

First, let's analyze the physical layer requirements. Access Points (APs) are the endpoints that provide wireless connectivity. In modern deployments, APs are typically powered via Power over Ethernet (PoE) to simplify cabling and installation. If you have just deployed the WLC, you must ensure that the network infrastructure connecting the APs can actually power them. Without PoE-capable switches, the APs will not function, rendering the WLC deployment useless. Therefore, deploying or verifying PoE switches is a critical, immediate dependency. This makes Option D a strong candidate.

Second, let's look at logical segmentation. A primary function of a WLC is to map Wireless LANs (SSIDs) to specific VLANs on the wired network. These VLANs allow for traffic segregation (e.g., separating guest traffic from corporate traffic). While VLANs might exist, the act of configuring these dynamic interfaces on the WLC and ensuring the corresponding VLANs are allowed on the trunk links between the switch and the WLC/APs is a crucial post-deployment task. However, looking at the options, "configure additional vlans" (Option B) suggests extending the VLAN topology to support the new wireless segments. This is a standard configuration step.

Let's evaluate the other options. Option A, deploying load balancers, is generally handled by the WLC itself (Dynamic Client Load Balancing) or is an enterprise-level feature not considered a basic "additional task" for a standard deployment. Option C, configuring multiple VRRP groups, is related to first-hop redundancy for the gateway, which is important but less directly tied to the wireless nature of the WLC than the physical power (PoE) and logical segmentation (VLANs) aspects. Option E, configuring additional security policies, is vague; while security is key, the specific technical dependencies for the WLC to operate are PoE and VLANs.

Comparing the community comments, there is a split between BE and BD. Commenters arguing for BE focus on logical configuration (VLANs and Security). However, the commenter arguing for BD points out a fundamental physical prerequisite: "You want POE so you can deploy access points." Without PoE, you cannot even connect the APs. Furthermore, the comment notes that "vlans so you can link dynamic interfaces to VLANs." This highlights that both physical power and logical segmentation are required. In many certification contexts, if the APs are not yet connected, PoE is the first hurdle. If they are connected, VLANs are the next. The question implies a fresh deployment context. Let's re-read carefully: "After you deploy a new WLAN controller...". Usually, this implies the controller is up, but the APs need to join it. For APs to join, they need IP (DHCP/VLANs) and Power (PoE).

However, looking at official Cisco guidance and common exam patterns, the most immediate "tasks" associated with enabling the wireless service are ensuring the infrastructure supports the APs (PoE) and defining where the wireless traffic goes (VLANs). Security policies are part of the WLC configuration but "configure additional security policies" is often a distractor compared to the hard infrastructure requirements. Wait, let's look closer at Option B vs D. Is "deploy POE switches" a task done after the WLC? Or is it part of the initial design? Often, questions like this assume the physical plant is being built alongside. But if I have to choose two, PoE and VLANs are the twin pillars of wireless connectivity. Security is secondary to availability. Load balancing is advanced. VRRP is routing. So it's between B/D and B/E.

Let's reconsider the wording "additional tasks". If the WLC is deployed, you configure the SSIDs. Each SSID maps to a VLAN. You must ensure those VLANs exist on the switches. You must ensure the APs are powered. Many sources cite PoE and VLANs as the key prerequisites. Let's look at the vote distribution. BE has 4+3+3+1+2 votes = 13. BD has 1+2 votes = 3. AE has 1. The majority leans BE. Why would E be better than D? "Configure additional security policies" might refer to setting up WPA2/WPA3, ACLs, etc. But is it more "critical" than PoE? No. However, in some exam logic, "Deploy POE switches" is considered pre-requisite infrastructure, not a task on the WLC or immediately following its software deployment. But the question says "consider", implying broader planning.

Actually, let's look at Objective 2.7: "Describe physical infrastructure connections of WLAN components (AP, WLC, access/trunk ports, and LAG)". This explicitly mentions APs and switches. And Objective 2.9 mentions GUI config for client connectivity.

Let's look at the "Correct Answer" usually associated with this specific legacy question. In many CCNA/CCNP dumps, the answer is often B and E or B and D. Let's use reasoning. If you deploy a WLC, you create WLANs. You bind them to VLANs. You secure them. Do you deploy switches? You might replace old ones. That's a big task. Configuring VLANs is a direct WLC/config task. Configuring security policies is a direct WLC task. Deploying PoE switches is a hardware procurement/install task. The question asks what to consider.

However, there is a nuance. If the APs are already in place, you don't need to deploy switches. If the network is greenfield, you do. The prompt doesn't specify. But "configure additional VLANs" and "configure additional security policies" are software/configuration steps that follow the WLC installation. "Deploy POE switches" is a physical layer activity that might have happened before. Therefore, B and E are the configuration tasks directly performed with or for the WLC.

Wait, looking at similar questions online, the answer is frequently B and E. The rationale is that once the controller is in, you define your networks (VLANs) and secure them (Security Policies). PoE is a baseline assumption or pre-existing condition in many scenarios, whereas VLANs and Security are the services you enable with the WLC.

Therefore, the correct options are B and E.
