DRAG DROP -
Refer to the exhibit. Drag and drop each traffic flow type from the left onto the corresponding number on the right. Not all traffic flow types are used. Select and Place:
This is an interactive task on the real exam — a drag-and-drop, hotspot or ordering question. There is nothing to select here, so the answer is shown below for reference.
Answer: See figure below
Refer to the exhibit. A Cisco data center environment is implemented with vPC. The web server replies using the SVI MAC address as the Layer 2 header instead of the HSRP MAC address on VLAN 23. This behavior causes packet drops on the Cisco Nexus 9000 Series Switches due to the vPC loop prevention mechanism. The requirement is for the vPC feature to allow N9K_1 and N9K_2 to forward traffic between the NAS server and the web server, even if the HSRP’s MAC address is not used on Layer 2 headers for VLAN 23. Which feature must be used to accomplish this goal?
Answer: D
DRAG DROP -
Refer to the exhibit. An engineer must provision a VXLAN deployment. The OSPF has already been configured as the underlay protocol. All BGP configurations will be performed using the template method. The deployment must meet these requirements: • The local update source for leaf switches must be loopback1. • The router ID must be the local loopback IP address. • The external BGP connections must use a template name. Drag and drop the configuration snippets from the bottom to complete the configuration.

Answer: See figure below
An engineer implements an environment with multiple traffic types on a consolidated I/O link between Cisco Nexus 9000 Series Switch and MDS 9000 Series Switch. The configuration must meet these requirements: • The unified I/O link must support LAN and SAN traffic. • A single, multipurpose Ethernet transport must be used. • The configuration must discard MAC addresses that are not part of the current fabric. • The QoS markings must be preserved. Which configuration set meets the requirements?
Answer: D
Answer is D Configuring the FC-Map You can prevent data corruption due to cross-fabric talk by configuring an FC-Map that identifies the Fibre Channel fabric for this switch. When the FC-Map is configured, the switch discards the MAC addresses that are not part of the current fabric.

Refer to the exhibit. A VXLAN data center fabric consists of three hosts mapped to different VLANs. Ingress VTEPs perform Layer 2 bridging and Layer 3 routing. Egress VTEPs only perform a Layer 2 bridging lookup. Which VNI values must be set to allow inter-VNI communication?
Answer: A
In VXLAN, for Layer3 routing, a VRF must be bound to a Layer3 VNI. This makes A or C possible valid choises. In the diagram we see that vlan 300 is very likely bound to Layer2 VNI 1010. So this means that answer C is not correct because if VNI 1010 is a Layer2 VNI, we must use a different VNI ID for Layer3 routing. This lets A likely to be the correct answer.

Refer to the exhibit. A network engineer must configure the physical domain and attach a VLAN pool to it. Which two commands accomplish this goal? (Choose two.)
Answer: AD
An engineer must perform a configuration backup of an existing Cisco UCS Manager environment. The backup file must contain all vNIC, vHBA, and service profile template settings. Also, the engineer must validate the backup before import and requires an XML output format. Which backup type must be used to meet these requirements?
Answer: C
I think is C. It should be Logical configuration with Preserve Identities box checked. "If this checkbox is selected for Logical Configuration type of backup operation, the backup file preserves all identities derived from pools, including vHBAs, WWPNs, WWNN, vNICs, MACs and UUIDs." https://www.cisco.com/c/en/us/td/docs/unified_computing/ucs/ucs-manager/GUI-User-Guides/Admin-Management/4-2/b_Cisco_UCS_Admin_Mgmt_Guide_4-2/m_backup_and_restore_configuration.html

An engineer is implementing VSANs on a Cisco MDS 9000 Series Switch with a native Fibre Channel. The deployment must meet these requirements: • The host on port fc1/1 must be assigned to VSAN 10. • The port channel 10 ISL must pass multiple VSANs, including VSAN 10. Which configuration set meets these requirements?
Answer: B
DRAG DROP - An engineer must authenticate OSPF on interfaces of the Cisco Nexus 9000 Series Switch so that: • eth1/1 uses clear text password. • eth1/2 uses encrypted md5 password. Drag and drop the commands from the bottom onto the boxes in the code to complete the configuration. Not all commands are used.

Answer: See figure below
Agree with it: clear text (config)#interface fastEthernet 0/0 (config-if)#ip ospf authentication (config-if)#ip ospf authentication-key TEST md5 (config)#interface fastEthernet 0/0 (config-if)#ip ospf authentication message-digest (config-if)#ip ospf message-digest-key 1 md5 TEST

An engineer must perform a backup and restore in Cisco UCS to rebuild the system in a disaster recovery scenario. The backup file must be encrypted to prevent the passwords from being stored as cleartext. Which backup configuration meets these requirements?
Answer: A
A full state backup is the appropriate choice when an engineer needs to perform a backup and restore in Cisco UCS for disaster recovery purposes. This type of backup includes a snapshot of the entire system and is saved as a binary file. Importantly, full state backups are encrypted, ensuring that passwords and other sensitive information are not stored as clear text. While TFTP (Trivial File Transfer Protocol) is not secure by itself, the encryption of the full state backup file provides the necessary security for the passwords within the backup.
