An engineer must build a VXLAN flood-and-learn network. The customer requires the solution to be based on the IETF documented practice in RFC 7348. The solution must use broadcast, unknown unicast, and multicast (BUM) and include the efficient BUM and short BUM replication modes that use only shared trees.
Which technology meets these requirements?
Which technology meets these requirements?
PIM sparse mode
PIM SSM
Bidirectional PIM
Data Center Network Services Design
A cloud service provider provisioned four active/active data centers in various locations within the country at 50 miles between each data center. The data centers must provide redundant network infrastructure and always be available to customers.
Which two data center design steps must be used to meet these requirements? (Choose two.)
Which two data center design steps must be used to meet these requirements? (Choose two.)
Provide application hosting services to customers from the closest data center.
Implement active cluster in data centers 1 and 2 and backup in 3 and 4.
Use asynchronous replication between data centers 1 and 2.
Deploy database services in data center 1 and application layer to other data centers.
Configure application data replication to all backup data centers.

Data Center Compute Connectivity Design
The end users report issues with datastore reachability between the newly installed virtual machines (VMs) and the storage array. The VMs are deployed on a Cisco C-Series server, directly connected with Cisco Nexus 5672UP switches over FCoE VLAN. The data traffic on VLAN 99, which is designated as a native VLAN, reaches its default gateway, but FCoE VLAN 99 fails to access the datastore. Which action resolves the problem?
Implement FCoE traffic on VLAN 10 and data traffic on VLAN 99.
Implement host-facing FCoE ports as spanning-tree port type edge.
Configure the FCoE VLAN in the VSAN database before including it in the trunk port.
Configure the FCoE VLAN traffic on a separate interface from any other VLANs that traverse the network.
Data Center Storage Connectivity Design
Which feature must be configured to connect a classical Ethernet network to a data center network so that the data center network appears to be one large switch?
vPC+
UDLD
EVPN
OSPF
Data Center Compute Connectivity Design
A network architect designs a high-availability architecture for the Cisco UCS Fabric Interconnects that are installed in a data center. The architecture must support clustering and redundancy.
Which architecture meets these requirements?

An engineer is designing a Cisco Nexus 7000 Series disaster recovery site using the data center interconnect solution to provide gateway redundancy and needs to ensure that devices use gateways in their own data centers.
Which design approach should be used to accomplish this goal?
Which design approach should be used to accomplish this goal?
CFS localized to its own data center

Server 1 fails to connect to the storage array over the Storage Area Network (SAN) of the Cisco NDS 9000 Series Switch. The requirements are to redesign the storage network and keep these considerations in mind:
• The traffic from each of the server must be redundant and isolated.
• The design must tolerate hardware and software failures and upgrades of SAN fabric devices.
Which action must be taken to meet these requirements?

Which action must be taken to meet these requirements?
Enable NPV and F-Port-channel on ports that face Server 1 on the Fibre Channel switch to create redundant paths.
Create a SAN port channel that faces the storage device to sustain a link failure.
Add an additional supervisor to the Fibre Channel switch to support nondisruptive upgrades.
Place an additional Fibre Channel switch to create two physically independent storage fabrics.
