Refer to the exhibit. Which VLANs are capable to be assigned on vPC interfaces?
Answer: D
D is correct. The PortChannel connecting the vPC peers should carry all the VLANs used by the vPC member ports. So the peer-link should carry all the vlans used via the other ports.

An engineer must apply AAA configuration on a Cisco MDS 9000 Series Switch. The solution must meet these conditions: ✑ It must use a challenge-response authentication protocol that uses MD5 hashing with an incrementally changing identifier. ✑ The RADIUS configuration must be automatically shared with other MDS switches in the environment. The RADIUS server is already defined. Which command set completes the configuration?
Answer: A

DRAG DROP - An engineer must configure remote authentication on a Cisco UCS system. The user password must be encrypted before it is sent to the authentication server. The company security policy requires the server to be based on an open standard. Drag and drop the UCS CLI AAA configuration commands from the left into the order in which they must be implemented on the right. Not all commands are used. Select and Place:

Refer to the exhibit. An engineer is creating a SPAN session to send a copy of all the Fabric-A VSAN 11 traffic on N5K_1 to the monitoring laptop. The configuration that presented has already been applied to Cisco UCS Manager. Which action competes the configuration?
Answer: D
A San traffic monitoring session has already been created. Select VSAN 11 as the source of traffic, not 1 there is a typo because the vsan should be 11.

Refer to the exhibit. The Cisco Nexus Series Switches SW1, SW2, and SW3 are connected via Layer 2 copper interfaces. An engineer implements loop prevention standard IEEE 802.1w on each VLAN to provide faster recovery from network changes or failures. The implementation has these requirements: ✑ Interfaces that are connected to Layer 2 hosts must not receive STP BPDUs. ✑ The implementation must detect unidirectional links due to one-way traffic twisted-pair links. ✑ Bridge assurance must be enabled between SW2 and SW3. ✑ The Layer 2 domain must be protected from superior BPDUs that arrive from external switches. Drag and drop the code snippets from the right onto the blanks in the code on the left to complete the configuration for SW3. Not all code snippets are used. Select and Place:

Config on sw3 must be like this: interface ethernet 1/4 spanning-tree port type network udld aggressive interface ethernet 1/5 spanning-tree guard root interface ethernet 1/6 spanning-tree port type edge Explanation: In the question, we have 4 most important requirements: ✑ Interfaces that are connected to Layer 2 hosts must not receive STP BPDUs. ✑ The implementation must detect unidirectional links due to one-way traffic twisted-pair links. ✑ Bridge assurance must be enabled between SW2 and SW3. ✑ The Layer 2 domain must be protected from superior BPDUs that arrive from external switches. 1st: command spanning-tree port type edge disables stp process on port 2nd: udld aggressive enables UDLD in aggressive mode 3rd: Bridge assurance is enabled globally by default on NX-OS. However, we do have to change the spanning-tree port type to network on interfaces 4th: Root guard is enabled with the interface command spanning-tree guard root. Root guard is placed on designated ports toward other switches that should never become root bridges.

Which virtualization feature is provided by network-attached storage?
Answer: B
An engineer must suggest deployment model for a newly developed application. The engineer has a small starting budget and lacks technical knowledge and infrastructure to implement storage, operating system, and database services to support the application deployment. The engineer also needs usage data related to the service and the ability to elastically scale the deployment as customer demands grow. Which two models must be used to meet the requirements? (Choose two.)
Answer: BE
because we are using public cloud.. and we will be using PaaS so we only manage the app.. not the infra or the OS! (but not consumig an app, like SaaS)

DRAG DROP - An engineer must configure Cisco UCS Manager to accept only HTTPS connections that use TLS 1.2. The cipher security level must be high and the length of the keyring key value must be 2048 bits. Drag and drop the code snippets from the right onto the blanks in the code on the left to accomplish these goals. Not all commands are used. Select and Place:
