A. All new APs that join the WLAN are assigned to the master controller.
B. The master controller is responsible for load balancing all connecting clients to other controllers.
C. All wireless LAN controllers are managed by the master controller.
D. Configuration on the master controller is executed on all wireless LAN controllers.

正解：B

質問 # 257
Refer to the exhibit.

An engineer is configuring an EtherChannel between Switch1 and Switch2 and notices the console message on Switch2. Based on the output, which action resolves this issue?

A. Configure the same EtherChannel protocol on both switches
B. Configure the same port channel interface number on both switches
C. Configure more member ports on Switch1.
D. Configure less member ports on Switch2.

正解：B

質問 # 258
Which definition describes JWT in regard to REST API security?

A. an encrypted JSON token that is used for authorization
B. an encrypted JSON token that is used for authentication
C. an encoded JSON token that is used to securely exchange information
D. an encoded JSON token that is used for authentication

正解：C

解説：
JWT: JSON Web Tokens are an open and standard (RFC 7519) way for you to represent your user's identity securely during a two-party interaction. That is to say, when two systems exchange data you can use a JSON Web Token to identify your user without having to send private credentials on every request.

質問 # 259

Refer to the exhibit. Both controllers are in the same mobility group. Which result occurs when client 1 roams between APs that are registered to different controllers in the same WLAN?

A. Client 1 contact controller B by using an EoIP tunnel.
B. The client database entry moves from controller A to controller B.
C. Client 1 users an EoIP tunnel to contact controller A.
D. CAPWAP tunnel is created between controller A and controller B.

正解：B

解説：
Explanation
This is called Inter Controller-L2 Roaming. Inter-Controller (normally layer 2) roaming occurs when a client roam between two APs registered to two different controllers, where each controller has an interface in the client subnet. In this instance, controllers exchange mobility control messages (over UDP port 16666) and the client database entry is moved from the original controller to the new controller.

質問 # 260
What are two considerations when using SSO as a network redundancy feature? (Choose two)

A. the multicast state is preserved during switchover
B. must be combined with NSF to support uninterrupted Layer 2 operations
C. must be combined with NSF to support uninterrupted Layer 3 operations
D. requires synchronization between supervisors in order to guarantee continuous connectivity
E. both supervisors must be configured separately

正解：C、D

解説：
Explanation

Cisco IOS Nonstop Forwarding(NSF) always runs with stateful switchover (SSO) and provides redundancy for Layer 3 traffic.

質問 # 261
Which tunneling technique is used when designing a Cisco SD-Access fabric data plane?

A. VXLAN
B. LISP
C. VRF Lite
D. VRF

正解：A

解説：

The tunneling technology used for the fabric data plane is based on Virtual Extensible LAN (VXLAN). VXLAN encapsulation is UDP based, meaning that it can be forwarded by any IP-based network (legacy or third party) and creates the overlay network for the SD-Access fabric. Although LISP is the control plane for the SD-Access fabric, it does not use LISP data encapsulation for the data plane; instead, it uses VXLAN encapsulation because it is capable of encapsulating the original Ethernet header to perform MAC-in-IP encapsulation, while LISP does not. Using VXLAN allows the SD-Access fabric to support Layer 2 and Layer 3 virtual topologies (overlays) and the ability to operate over any IP-based network with built-in network segmentation (VRF instance/VN) and built-in group-based policy.

質問 # 262
Wireless users report frequent disconnections from the wireless network. While troubleshooting a network engineer finds that after the user a disconnect, the connection re-establishes automatically without any input required. The engineer also notices these message logs .

Which action reduces the user impact?

A. enable coverage hole detection
B. increase BandSelect
C. increase the AP heartbeat timeout
D. increase the dynamic channel assignment interval

正解：D

質問 # 263
Refer to the exhibit.

Refer to the exhibit. Traffic is not passing between SW1 and SW2. Which action fixes the issue?

A. Configure LACP mode on S1 to active.
B. Configure PAgP mode on S1 to desirable.
C. Configure LACP mode on S1 to passive.
D. Configure switch port mode to ISL on S2.

正解：B

質問 # 264
How does QoS traffic shaping alleviate network congestion?

A. It drops packets randomly from lower priority queues.
B. It drops packets when traffic exceeds a certain bitrate.
C. It buffers and queue packets above the committed rate.
D. It fragments large packets and queues them for delivery.

正解：C

解説：
Traffic shaping retains excess packets in a queue and then schedules the excess for later transmission over increments of time. The result of traffic shaping is a smoothed packet output rate

質問 # 267
What is a characteristic of MACsec?

A. 802.1AE is negotiated using Cisco AnyConnect NAM and the SAP protocol
B. 802.1AE is bult between the host and switch using the MKA protocol, which negotiates encryption keys based on the master session key from a successful 802.1X session
C. 802.1AE provides encryption and authentication services
D. 802.1AE is bult between the host and switch using the MKA protocol using keys generated via the Diffie-Hellman algorithm (anonymous encryption mode)

正解：C

解説：
Explanation
MACsec, defined in 802.1AE, provides MAC-layer encryption over wired networks by using out-of-band methods for encryption keying. The MACsec Key Agreement (MKA) Protocol provides the required session keys and manages the required encryption keys. MKA and MACsec are implemented after successful authentication using the 802.1x Extensible Authentication Protocol (EAP-TLS) or Pre Shared Key (PSK) framework.
