Exhibit.A customer is reporting mat connectivity is Tailing for some wireless client Devices. What are your conclusions from the capture? (Select two.)
Answer(s): B,D
The capture shows messages related to WPA key management, indicating WPA2-PSK is being used. Also, the capture includes a DHCP request from the client but no corresponding DHCP ACK, suggesting the client is not receiving an IP address, which could explain the connectivity failure.
Which statements accurately describe OSPF Graceful Restart (when the restarting router is able to Keep its forwarding tables across the restart)? (Select two.)
Answer(s): A,D
Graceful Restart (GR) allows a router to continue forwarding packets while it restarts its OSPF process. The GR helper role on AOS-CX switches supports routers during this process. OSPF routers listen for Grace-LSAs to identify neighbors undergoing a graceful restart, maintaining adjacencies with those routers to allow uninterrupted forwarding.
What directly affects the MCS used by wireless stations? (Select two.)
Answer(s): A,E
The Modulation and Coding Scheme (MCS) used by wireless stations is directly affected by the signal- to-noise ratio (SNR) and the frequency band. Higher SNR can lead to higher MCS values, which means better data rates. The frequency band can affect MCS due to different channel characteristics, such as the presence of interference and propagation properties, which are factors in determining data rates.
A campus topology uses VSX with a collapsed core topology. The customer added redundant SFP+ transceivers and reconfigured their mobility gateways from a single link to an aggregate Link. You are asked to verify the CLI output for the link aggregation configuration for one of the mobility gateway cluster members below.What is a valid configuration?A)B)C)D)
Answer(s): A
The configuration shown in Option A is a valid configuration for a multi-chassis link aggregation (MC- LAG) setup. It specifies the use of LACP (Link Aggregation Control Protocol) with a fast rate of LACP PDUs exchange, which is appropriate for creating a resilient and high-throughput link aggregation. The 'vlan trunk allowed all' command allows all VLANs across the trunk, and 'vlan trunk native 100' sets VLAN 100 as the native VLAN for untagged traffic.
A customer is running out of IP addresses in a network segment. What will happen If they add an additional IPsubnet to the same VLAN?
Answer(s): D
Adding an additional IP subnet to the same VLAN means that devices configured with either subnet can communicate at Layer 2 without the need for routing. This is because they are on the same VLAN and thus in the same broadcast domain. However, to communicate between subnets, an L3 device or inter-VLAN routing would be required.
