During the initial setup of a FlexPod solution, an administrator is configuring the Cisco UCS Fabric Interconnects. To ensure that both Fabric Interconnects actively forward traffic for different sets of VLANs and act as the root bridge for their respective sets, which feature must be configured on the upstream Nexus switches?
Answer and explanation
Correct answer: B
Virtual Port Channel (vPC) allows both Nexus switches in a pair to appear as a single logical switch to the downstream device (the UCS Fabric Interconnects). This enables the configuration of a port channel across two physical switches, allowing for active-active forwarding paths without being blocked by Spanning Tree Protocol. The UCS FIs can then be configured in an active-active manner for different VLANs, with proper STP root guard and other features ensuring a loop-free topology.
Question 2
A solutions architect is designing a new FlexPod environment for a mixed-workload VDI deployment. A key requirement is to provide consistent, low-latency performance for persistent desktops while also cost-effectively storing user profile data that is accessed less frequently. Which NetApp storage configuration best meets these requirements within a single storage system?
Answer and explanation
Correct answer: C
A NetApp FAS system with Flash Pool is the ideal solution for this scenario. Flash Pool allows the creation of aggregates that contain both SSDs and HDDs. The SSDs act as a high-performance cache, accelerating reads and writes for frequently accessed data like VDI boot volumes and active user sessions. The HDDs provide a cost-effective capacity tier for less frequently accessed data, such as user profiles and archives, all within the same aggregate and managed automatically by ONTAP.
Question 3
An administrator is troubleshooting a SAN boot issue where a newly provisioned Cisco UCS B-Series blade fails to see its boot LUN from a NetApp AFF array. The zoning on the Cisco MDS switches is confirmed correct, and other blades in the same chassis can boot successfully using similar service profile templates. The administrator observes that the vHBA on the failing blade remains offline. What is the most likely cause of this issue within the UCS Manager configuration?
Answer and explanation
Correct answer: A
For a vHBA to come online, it must be associated with a VSAN that is configured on the Fabric Interconnects and permitted on the uplink Fibre Channel ports connecting to the MDS switches. If the VSAN is missing from the uplink port's allowed list, the Fabric Interconnect cannot perform the necessary FLOGI (Fabric Login) on behalf of the vHBA, causing it to remain offline. Since zoning and other blades are correct, this points to a specific configuration issue related to the blade's service profile or the underlying network fabric configuration within UCS.
Question 4
Multiple answers
A FlexPod administrator needs to perform a firmware upgrade on multiple Cisco UCS B-Series blades. To ensure consistency and minimize manual effort, the administrator decides to use policies within UCS Manager. Which TWO policies are essential for managing the firmware versions of the blade server components? (Select TWO)
Answer and explanation
Correct answers: A, C
Question 5
True or False: In a standard FlexPod deployment, a vPC (Virtual Port Channel) peer-link must be established directly between the two Cisco UCS Fabric Interconnects to enable active-active uplinks.
Answer and explanation
Correct answer: B
This statement is false. The two Cisco UCS Fabric Interconnects form a high-availability cluster and are connected by dedicated L1/L2 ports for cluster communication. They do not use vPC between themselves. The vPC is configured on the upstream Cisco Nexus switches, making the pair of switches appear as a single logical switch to the Fabric Interconnects.
Question 6
Multiple answers
A consultant is gathering requirements for a new FlexPod deployment that will host a sensitive database application. The customer has a strict security requirement that all administrative access to the NetApp storage system must be logged and auditable. Furthermore, management traffic must be isolated from data traffic. Which two components should be configured on the NetApp storage system to meet these requirements? (Select TWO)
Answer and explanation
Correct answers: B, D
Question 7
When creating a Service Profile in Cisco UCS Manager, an administrator needs to assign a unique identifier to the server's virtual HBAs that will be used for SAN booting. From which pool is this identifier drawn?
Answer and explanation
Correct answer: C
World Wide Port Names (WWPNs) are the unique identifiers used for Fibre Channel devices, such as Host Bus Adapters (HBAs) and virtual HBAs (vHBAs). When configuring a service profile for SAN connectivity, the WWPN for each vHBA is drawn from a pre-configured WWPN Pool in UCS Manager. This ensures that each vHBA has a unique identity on the SAN fabric.
Question 8
A financial firm requires a FlexPod design that can survive a complete site failure with zero data loss (RPO=0) and a near-zero recovery time (RTO). The two sites are 50 km apart and have high-bandwidth, low-latency dark fiber links. Which combination of NetApp technology and Cisco networking design should be proposed?
Answer and explanation
Correct answer: B
NetApp MetroCluster provides synchronous replication between two sites, ensuring zero data loss (RPO=0) in the event of a site failure. It allows for automated or push-button site failover, meeting the near-zero RTO requirement. Cisco Overlay Transport Virtualization (OTV) is a technology designed to extend Layer 2 connectivity across different data centers over a Layer 3 network, which is essential for stretching the VLANs required for a seamless failover of applications and virtual machines in an active-active or active-passive data center design.
Question 9
Case Study:
A healthcare organization is refreshing its data center with a new FlexPod solution to support its Electronic Health Record (EHR) system. The solution must comply with HIPAA regulations, which mandate data encryption at rest and strict access controls. The current environment consists of physical servers that will be virtualized onto the new platform.
The project requirements are as follows:
All patient data stored on the NetApp array must be encrypted.
The virtualization platform will be VMware vSphere.
Network traffic for vMotion and storage access must be isolated from the main production network.
The solution must be built according to the latest Cisco Validated Design (CVD) for FlexPod with VMware.
An administrator is tasked with the initial storage configuration on a NetApp AFF A250 system. To meet the encryption requirement, the administrator enables NetApp Volume Encryption (NVE). For network isolation, separate VLANs and dedicated vNICs in the UCS service profiles are planned for vMotion and iSCSI traffic. What additional step is crucial for securing data access on the newly created iSCSI LUNs that will host the VMware datastores?
Answer and explanation
Correct answer: B
While NVE handles data encryption at rest, access control is equally critical for security and compliance. For iSCSI, the standard mechanism for access control is the initiator group (igroup). An igroup on the NetApp array contains the unique iSCSI Qualified Names (IQNs) of the authorized initiators (the ESXi hosts). By creating an igroup with the hosts' IQNs and then mapping that igroup to the LUNs, the administrator ensures that only those specific ESXi hosts can discover and access the datastores. This prevents unauthorized servers from accessing sensitive patient data.
Question 10
A FlexPod administrator observes high network utilization alerts from OnCommand Unified Manager for a specific SVM. Investigation reveals that a single, high-traffic virtual machine is consuming a disproportionate amount of bandwidth. Which feature, configured in both Cisco UCS Manager and the Nexus switches, can be used to limit the bandwidth for the vNIC associated with this VM?
Answer and explanation
Correct answer: C
Quality of Service (QoS) is the mechanism used to manage network traffic and enforce bandwidth policies. In a FlexPod environment, a QoS policy can be created in Cisco UCS Manager to define a rate limit or priority for specific traffic classes. This policy is then applied to the vNIC template used by the problematic VM's service profile. The configuration must be consistent end-to-end, meaning corresponding QoS policies should also be configured on the upstream Nexus switches to honor the markings and enforce the policies as traffic leaves the UCS domain.
