Question 2

An engineer is troubleshooting a UCS blade server that fails to boot from SAN. The server is associated with a service profile that includes a SAN connectivity policy. Which two items should be verified to ensure the boot from SAN works? (Choose two.)

Accepted Answer

The boot policy includes the SAN target as the first boot device.. For boot from SAN, the WWPNs must be correctly assigned and the boot policy must list the SAN path as the first boot device. Also, zoning on the SAN switch is required but that is external.

Answer

The vNIC placement policy is set to fabric failover.

Answer

The QoS policy is applied to the vHBA.

Answer

The server has a local disk installed.

Question 3

An engineer is configuring a UCS service profile for a blade that will boot from local disk. The blade has two SAS drives configured as a RAID 1 mirror. Which policy is required to specify the local disk boot order?

Accepted Answer

Boot policy. The boot policy in a service profile defines the boot order and boot devices. For local disk boot, the boot policy must list the local disk as the primary boot device.

Answer

SCSI policy

Answer

Disk policy

Answer

Storage policy

Question 4

In a Cisco HyperFlex cluster, which component is responsible for ensuring data redundancy and consistency across nodes, and typically requires a separate VM for proper operation?

Accepted Answer

Cluster Witness VM. The cluster witness VM (arbiter) is used in HyperFlex for quorum decisions and to prevent split-brain scenarios, especially with RF2.

Answer

Cisco IMC

Answer

HyperFlex Data Platform (HXDP) controller

Answer

vCenter Server

Question 5

A UCS blade server has two vHBAs configured. The storage array is connected to both Fabric Interconnects. Which multipathing configuration should be used on the host to provide path redundancy without needing additional storage ports?

Accepted Answer

Active/active multipathing. With two vHBAs connected to two separate FIs, the host can use active/active multipathing (e.g., ALUA or symmetric) to utilize both paths simultaneously for redundancy and load balancing.

Answer

Active/passive multipathing

Answer

Single path with failover

Answer

Round-robin I/O scheduling

Question 6

A UCS administrator needs to perform a firmware upgrade on a UCS B-Series blade server. Which management interface should be used to perform the upgrade remotely?

Accepted Answer

UCS Manager. UCS Manager provides centralized firmware management for all blades and FIs. The administrator can initiate firmware updates through UCS Manager GUI or CLI, which handles the upgrade process across the domain.

Answer

HyperFlex Connect

Answer

Cisco IMC Supervisor

Answer

CIMC of the blade server

Question 7

An engineer is configuring a UCS service profile for a blade server that will boot from SAN. The storage is connected via FC SAN. Which policy must be included in the service profile to define the WWPNs for the HBAs?

Accepted Answer

SAN connectivity policy. To boot from SAN, the service profile must include a SAN connectivity policy that defines the WWPNs (World Wide Port Names) for the vHBAs. This policy assigns WWPNs from a pool or statically.

Answer

Network control policy

Answer

Boot policy

Answer

vNIC placement policy

Question 8

An administrator needs to replace a faulty UCS B200 M5 blade with a new blade of the same model. The original blade had a service profile associated. What is the minimum required action to allow the new blade to take over the workload with the same configuration?

Accepted Answer

Disassociate the service profile from the faulty blade and associate it with the new blade.. UCS service profiles provide hardware abstraction, making blades stateless. Simply inserting the new blade will not automatically associate the profile; the administrator must re-associate the service profile with the new blade. No other reconfiguration is needed if the new blade is identical.

Answer

Clone the service profile and then associate the clone with the new blade.

Answer

Manually reconfigure the new blade via the KVM console.

Answer

Update the firmware on the new blade to match the service profile requirements.

Question 9

In a UCS service profile, which construct is used to abstract the network interface configuration so that the same profile can be used with different blade models?

Accepted Answer

vNIC template. vNIC templates define network interface properties (MAC address, VLANs, fabric assignment) and can be policy-based, allowing hardware abstraction.

Answer

Boot policy

Answer

Local disk policy

Answer

Server pool policy

Question 10

An engineer is deploying a HyperFlex cluster with three nodes using all-flash storage and replication factor 2 (RF2). What is the minimum number of nodes required to tolerate a single node failure?

Accepted Answer

3. With RF2, data is replicated to two nodes. If one node fails, the other node still holds a copy, so the cluster continues. However, for strict fault tolerance, a witness VM is needed to avoid split-brain. Three nodes with RF2 can tolerate one node failure.

Question 11

Which management interface is used for out-of-band configuration and remote KVM access to a standalone UCS C-series rack server?

Accepted Answer

CIMC. Cisco Integrated Management Controller (CIMC) provides out-of-band management, including remote KVM, virtual media, and firmware updates.

Answer

UCS Central

Answer

Cisco IMC Supervisor

Answer

UCS Manager

Question 12

An engineer is deploying a HyperFlex cluster and needs to ensure that if a disk fails in a hybrid node, the system can rebuild the data from parity. Which RAID configuration is required on the disk controller for the cache SSD and HDDs in a HyperFlex hybrid node?

Accepted Answer

RAID 0 for SSD and RAID 5 for HDDs. In HyperFlex hybrid nodes, the cache SSD is configured as RAID 0 (striping without parity) for performance, while the HDDs can be configured as RAID 5 or RAID 6 for redundancy. For the SSD cache, RAID 0 is typically used because data is replicated at the cluster level.

Answer

RAID 6 for SSD and RAID 0 for HDDs

Answer

RAID 10 for both SSD and HDDs

Answer

RAID 1 for SSD and RAID 5 for HDDs

Question 13

Which THREE factors should be considered when calculating the required number of buffer credits for a long-distance Fibre Channel link? (Choose three.)

Accepted Answer

The link data rate (e.g., 16 Gbps).. Buffer credits are calculated using the link data rate (affects how many bits can be transmitted per second), the maximum frame size (determines how many bytes are consumed per credit), and the distance between switches (affects propagation delay and round-trip time). Therefore, options A (data rate), B (frame size), and E (distance) are correct. VSAN count (C) and zone count (D) have no impact on buffer credit calculations.

Answer

The number of VSANs configured.

Answer

The number of zones in the fabric.

Question 14

Which THREE security features are commonly used on Cisco Nexus switches to prevent DHCP-based attacks? (Choose three.)

Accepted Answer

DHCP snooping. DHCP snooping is a security feature that acts as a firewall between untrusted hosts and DHCP servers. It filters DHCP messages by validating DHCP packets received on untrusted ports, dropping those that are invalid (e.g., DHCP server messages from a client port), and building a DHCP snooping binding database that maps client MAC addresses, IP addresses, VLAN, and port information. This database is then used by other features like IP Source Guard and Dynamic ARP Inspection to prevent IP spoofing and ARP poisoning attacks.

Answer

Control Plane Policing (CoPP)

Answer

Port security

Question 15

In a BGP EVPN deployment, route type 2 (MAC/IP advertisement) is used to advertise MAC addresses. What additional information is carried in route type 2 for IP routing?

Accepted Answer

IP address and MAC address. In BGP EVPN, route type 2 (MAC/IP Advertisement Route) is used to advertise both MAC addresses and their associated IP addresses. The additional information carried for IP routing is the IP address and the MAC address, enabling the control plane to support both Layer 2 bridging and Layer 3 routing (e.g., host route advertisement for IP-based forwarding). This is defined in RFC 7432, where the route type 2 NLRI includes a MAC address field and an optional IP address field.

Answer

IP address and route distinguisher

Answer

IP prefix and next-hop

Answer

MAC address and VNI
