Q: 1
An international corporation migrates its primary and secondary data centers to Cisco ACI. The new
architecture must include a disaster recovery solution for critical applications in the primary data
center with these requirements:
The secondary data center hosts dedicated workloads, which must remain isolated from the primary
data center.
Critical applications must have both Layer 3 and Layer 2 connectivity between data centers.
The ACI policy must be consistent across the data centers.
Flooding between the data centers must be restricted to specific VLANs.
Which solution must be used to accomplish these goals?

Q: 4
Refer to the exhibit. A Cisco engineer is configuring a PBR in a Cisco ACI data center scenario and
plans to insert a transparent firewall. The APIC release is 4.1. the Cisco ACI fabric is configured to be
the gateway for the servers and for the PBR node, and the Layer 4/ Layer 7 devices are deployed as
Layer 1/ Layer 2 mode in the physical domain. Layer 1/Layer 2 PBR node interfaces arc also
configured to be in a bridge domain and not in an L30ut. What is required for the consumer and
provider connectors of the Layer 1/Layer 2 device for this scenario to work?

Q: 7
Refer to the exhibit. A Cisco engineer is configuring a data center design scenario with Cisco MDS
90Q0 Series Switches. The cut-through routing mode is chosen for impf oved read operation
performance. Each (SCSI host requires access lo storage through the IPS module. First, the engineer
configures the TCP tuning parameters as enabled SACK, the maximum bandwidth of 1 Gbps. buffer
size of 4096. keepalive timeout at 1s. and enables Path MTU. Then, the engineer must set the OoS of
the ISCSI link. What is the maximum QoS value that must be set tor the ISCSI session?

A customer is deploying a SAN based on Cisco MDS 9000 Series Switches. Each Inter-Switch Link must
carry multiple VSANs at the same time. The access switch must share the same domain ID as the
director switch to reduce the number of domain IDs needed in the fabric Drag and drop the
operational port types from the right onto the boxes on the left to create a topology that meets
these requirements. Not all port types are used. Port types are used more than once.

Q: 10
Refer to the exhibit.
Fiber links are provisioned directly between the spine and leaf switches in the given LAN topology
A/30 prefix has been configured over each fiber link to provide underlay connectivity for a VXLAN
network. The network-engineering team must update the network configuration to provide the
shortest possible convergence time if a fiber link is cut. Which action must the team take to meet the
requirement?

Q: 13
A Cisco engineer is analyzing a customer environment where dozens of VMs are running on a
physical server and UCS chassis are cascaded The setup uses two ISLs in a port channel to the SAN
switch (per fabric) The oversubscription from VM to physical SAN port is often 20 (VMs/host) x 72 (9
UCS chassis cascaded = 72 hosts): 2 (ISLs from fabric interconnect to SAN switch port on the NPV core
(NPIV enabled switch) This results to 20 x 72 2 per single ISL = 720 VMs per ISL
20 (VMs per host) x 8 (hosts per chassis) x 9 (chassis per port channel to SAN switch) / 2 (ISLs per port
channel) = 20 x 8 x 9 / 2 = 720 VMs per SAN F-port What is the best way to resolve possible IOPS
bottleneck?

Q: 14
An engineer is installing a Cisco Nexus 7000 Series Switch with F2-Series I/O Module. The company's
strict security policy requires that the port be in-band. The engineer must also keep these
considerations in mind:
The customer's security requirements mandate the use of a secure management mechanism that
supports authentication and encryption.
The port should support management over IP.
Which port type must be used to meet these requirements?

Q: 15
Refer to the exhibit During a synchronization of port rotes, a device receives a proposal message on
one of its ports that is selected as the new root port. The logs show that Rapid PVST+forced all other
ports to synchronize with the new loot information. The engineer analyzes the port stales and
concludes that the device is synchronized with superior root information received on the root port,
and all other ports are synchronized. What happens to a designated port that is in the forwarding
state and is not configured as an edge port, if Rapid PVST+ forces it to synchronize with new root
information?

Q: 16
A network consultant evaluates the Cisco UCS Fabric Interconnect SAN configuration, which must
meet these requirements:
All traffic must pass over the upstream device for switching and domain IDs must be preserved in the
fabric.
Each server should be pinned to one designated upstream interface and for the traffic to pass
through the pinned port.
