Exam 200-301 topic 1 question 555 discussion

Passive clients are wireless devices, such as scales and printers that are configured with a static IP address. These clients do not transmit any IP information such as IP address, subnet mask, and gateway information when they associate with an access point. As a result, when passive clients are used, the controller never knows the IP address unless they use the DHCP. https://www.cisco.com/c/en/us/td/docs/wireless/controller/7-4/configuration/guides/consolidated/b_cg74_CONSOLIDATED/m_configuring_passive_clients.html

A is correct. Static IP should be excluded from the DHCP pool.

C is correct

This question seems to be asking what feature should be enabled on the WLC. A -> WRONG. Client exclusion refers to a mechanism to prevent overload caused by malicious/faulty EAP clients. B -> WRONG The IP is static; DHCP address assignment doesn't work here. D -> WRONG Static IP tunneling (Dynamic Anchoring) is if you want to configure a Static IP address on a device that may move around the network, to ensure connectivity even if it associates with another WLC. So that only leaves C, which is right anyway because enabling Passive Client is necessary to ensure that the controller can learn static IP addresses, which it otherwise wouldn't because devices with a static IP don't transmit that information when connecting to an AP. See: https://www.cisco.com/c/en/us/td/docs/wireless/controller/9800/16-12/config-guide/b_wl_16_12_cg/passive-client.html#concept_FC84F350446D4D76A965400D13DA122A

if the printer have a static ip address, DHCP service must be properly configured to prevent IP address conflicts in the network.

B for me

COULOOKPS C

Passive clients are wireless devices, such as scales and printers that are configured with a static IP address. These clients do not transmit any IP information such as IP address, subnet mask, and gateway information when they associate with an access point. As a result, when passive clients are used, the controller never knows the IP address unless they use the DHCP. https://www.cisco.com/c/en/us/td/docs/wireless/controller/7-6/configuration-guide/b_cg76/b_cg76_chapter_01100000.html

Correct answer is C and here is a short explanation of why: A) Client exclusion is a timeout forced on devices that repeatedly fail to connect B) There is an option to force DHCP address assignment for devices on a WLAN but this would prevent the device with a static IP from connecting C) Passive client enabled for devices that are quiet like those with static IPs D) Static IP tunneling is for passing a device with a static address over a mobility tunnel to another WLC that does not have the device's subnet in its interface ranges or groups.

google is ur friend hhhh btw "C" is the correct answer

Passive clients are wireless devices, such as scales and printers that are configured with a static IP address. These clients do not transmit any IP information such as IP address, subnet mask, and gateway information when they associate with an access point. As a result, when passive clients are used, the controller never knows the IP address unless they use the DHCP.

B (DHCP address assignment) is correct because DHCP Address Allocation Mechanism (or assignment) is the mechanism (Manual Allocation) we're going to use to Provide an IP address to a client manually.

I also think the answer is C. The questions states that the printer is being assigned an address statically so why would we need to have DHCP address assignment?

Isn't a DHCP reservation a 'DHCP address assignment' It is a poor wording but the same thing

Can anyone explain to me why letter C is not the correct answer here? It should be C, passive client feature, based on this Cisco link: https://www.cisco.com/c/en/us/td/docs/wireless/controller/7-4/configuration/guides/consolidated/b_cg74_CONSOLIDATED/m_configuring_passive_clients.html DHCP address assignment is just the DHCP DORA process, not DHCP exclude feature. Client exclusion is yet another feature not related to DHCP excluding feature.

DHCP address assignment must be there way of saying DHCP reservation

For enhanced security, we recommend that you require all clients to obtain their IP addresses from a DHCP server. To enforce this requirement, you can configure all WLANs with a DHCP Addr. Assignment Required setting, which disallows client static IP addresses. If DHCP Addr. Assignment Required is selected, clients must obtain an IP address via DHCP. Any client with a static IP address is not allowed on the network. The controller monitors DHCP traffic because it acts as a DHCP proxy for the clients. https://www.cisco.com/c/en/us/td/docs/wireless/controller/7-4/configuration/guides/consolidated/b_cg74_CONSOLIDATED/b_cg74_CONSOLIDATED_chapter_01001001.html
