350-601 Practice Test 45 — 15 Questions

Question 1

In a UCS service profile, which configuration allows a blade server to boot from a SAN LUN without local storage?

Accepted Answer

Define a SAN boot policy and assign it to the service profile with the boot order set to SAN.. Boot from SAN is configured in the service profile by specifying a SAN boot policy that defines the WWPN, LUN ID, and target details. This enables stateless boot from a SAN-attached LUN.

Answer

Enable PXE boot in the service profile.

Answer

Configure local disk as RAID and use it for boot.

Answer

Set the boot order to local disk first, then SAN.

Question 2

An engineer is integrating a UCS C-series rack server into UCS Manager. The server is currently managed by CIMC. Which mode must be enabled on the C-series server to allow UCS Manager to discover and manage it?

Accepted Answer

UCS-Managed mode. UCS Manager can manage C-series servers in UCS-Managed mode, which requires the server to be in UCSM mode via CIMC.

Answer

Standalone mode

Answer

Cisco IMC Supervisor mode

Answer

Direct Connect mode

Question 3

A company plans to deploy multiple UCS domains across different geographical locations. They want a single pane of glass to manage service profiles globally. Which Cisco solution should be used?

Accepted Answer

UCS Central. UCS Central provides centralized management of multiple UCS domains, enabling global service profile policies and management across domains.

Answer

UCS Manager

Answer

HyperFlex Connect

Answer

Cisco IMC Supervisor

Question 4

A UCS C-Series server is initially deployed in standalone mode using CIMC. Later, the server is moved into a UCS domain managed by UCS Manager. What must be done to the CIMC configuration to allow UCS Manager to take control?

Accepted Answer

Change the CIMC management mode from standalone to UCS-managed.. To integrate a standalone C-Series server into UCS Manager, the server must be reset to factory defaults (or the management mode changed to UCS-managed) and then discovered by the Fabric Interconnect.

Answer

Disable the CIMC interface and use only UCS Manager.

Answer

Update the CIMC firmware to the latest version.

Answer

Install a Cisco VIC adapter in the server.

Question 5

In a HyperFlex cluster with hybrid nodes (HDD+SSD), which statement best describes the role of the SSD cache?

Accepted Answer

SSD acts as a write cache and read cache to accelerate I/O.. In HyperFlex, the SSD (or flash) in hybrid nodes serves as a cache for frequently accessed data, while the HDDs provide bulk storage. The HXDP uses SSDs for both caching and persistent storage in all-flash nodes.

Answer

SSD is used only for metadata storage.

Answer

SSD is used for long-term persistent storage, while HDD is used for caching.

Answer

SSD is not used; all data is stored on HDD.

Question 6

Which of the following best describes stateless computing in Cisco UCS?

Accepted Answer

All server configuration is stored in the service profile, allowing any physical blade to assume the identity.. Stateless computing means that all configuration (BIOS, firmware, network, storage settings) is stored in the service profile on UCS Manager, not on the server. Thus, a failed blade can be replaced without reconfiguration.

Answer

VLANs and VSANs are not configured on the Fabric Interconnects.

Answer

Server state is saved to a local disk for recovery.

Answer

The server has no operating system installed.

Question 7

After adding a new spine switch to a VXLAN EVPN fabric with OSPF underlay, some leaf switches experience routing instability. Which action could resolve the instability?

Accepted Answer

Increase the OSPF cost on the leaf-to-spine links.. When a new spine switch is added to a VXLAN EVPN fabric with an OSPF underlay, the leaf switches may experience routing instability because the new spine advertises routes with a lower cost, causing traffic to shift abruptly. Increasing the OSPF cost on the leaf-to-spine links makes those paths less preferred, stabilizing the routing table by preventing flapping and ensuring a more gradual convergence.

Answer

Configure OSPF neighbor authentication.

Answer

Decrease the OSPF hello timer.

Answer

Enable OSPF route summarization on the leaves.

Question 8

Which BGP variant is commonly used in spine-leaf fabrics to advertise EVPN routes for VXLAN?

Accepted Answer

MP-BGP with EVPN address family. MP-BGP with the EVPN address family (AFI 25 / SAFI 70) is the control-plane protocol used in VXLAN spine-leaf fabrics to advertise MAC/VTEP reachability, host routes, and integrated routing and bridging (IRB) information. This allows the spine to act as a route reflector, distributing EVPN type-2 (MAC/IP) and type-3 (IMET) routes to all leaf nodes, enabling efficient, loop-free overlay forwarding.

Answer

OSPF with opaque LSA

Answer

eBGP with standard IPv4 unicast

Answer

iBGP with standard IPv4 unicast

Question 9

In a VXLAN EVPN fabric with MP-BGP, which route type is used to advertise MAC addresses and associated VNI?

Accepted Answer

Type 2: MAC/IP Advertisement. Type 2 (MAC/IP Advertisement) routes are used in VXLAN EVPN fabrics with MP-BGP to advertise MAC addresses, their associated VNI, and optionally IP addresses. This route type enables the control plane to distribute host reachability information, allowing VTEPs to build and update their forwarding tables dynamically.

Answer

Type 3: Inclusive Multicast Ethernet Tag

Answer

Type 1: Ethernet Auto-Discovery

Answer

Type 5: IP Prefix

Question 10

A UCS administrator must ensure that a service profile can be updated without disrupting production traffic. Which two configuration options support this requirement? (Choose two.)

Accepted Answer

Maintenance policy with 'User Ack' and 'Enable Fast Reboot'. A maintenance policy with 'User Ack' requires manual acknowledgment before the update proceeds, and enabling 'Fast Reboot' minimizes traffic disruption by reducing the reboot time. Option E is correct because a maintenance policy with 'On Next Boot' defers the update until the next scheduled reboot, allowing the administrator to control when the change takes effect and avoid impacting production traffic.

Answer

Use of a service profile template with 'Disruptive Update'

Answer

Maintenance policy with 'Immediate'

Answer

Use of a service profile template with 'Upgrade Policy'

Question 11

Which TWO security features are used to prevent MAC address flooding attacks on a Cisco Nexus switch? (Choose two.)

Accepted Answer

Port Security. Port Security (A) is correct because it limits the number of MAC addresses allowed on a switch port, preventing MAC flooding attacks by dropping frames from unknown source MACs once the limit is exceeded. DHCP Snooping (D) is correct because it builds a trusted database of IP-to-MAC bindings from DHCP messages, which can be used to validate traffic and prevent MAC spoofing that often accompanies flooding attacks.

Answer

IP Source Guard

Answer

Control Plane Policing

Answer

BPDU Guard

Question 12

Which STP variant provides per-VLAN load balancing and is commonly used in data center networks with Cisco Nexus switches?

Accepted Answer

Rapid PVST+. Rapid PVST+ (Per-VLAN Spanning Tree Plus) is the correct answer because it provides per-VLAN load balancing by running a separate instance of RSTP (802.1w) for each VLAN. This allows different VLANs to use different root bridges and forwarding paths, enabling traffic load sharing across redundant links. Cisco Nexus switches support Rapid PVST+ as a default or commonly configured STP variant in data center environments, offering fast convergence and VLAN-based traffic engineering.

Answer

MST

Answer

RSTP

Answer

STP

Question 13

A UCS C-Series rack server with a boot from SAN policy fails to discover the LUN during POST. The HBA is correctly zoned with the storage array. Which step should be taken to troubleshoot the issue?

Accepted Answer

Review the SAN boot target configuration in Cisco IMC. When a UCS C-Series rack server with a boot-from-SAN policy fails to discover the LUN during POST, the most direct troubleshooting step is to review the SAN boot target configuration in Cisco IMC. The HBA is already correctly zoned, so the issue likely lies in the boot target parameters (e.g., WWPN, LUN ID, or target name) configured in the IMC's SAN boot settings, which the HBA uses during the BIOS-level boot process. Verifying these settings ensures the HBA can properly address and log into the storage target.

Answer

Verify VSAN membership on the fabric interconnect

Answer

Update the server firmware to the latest version

Answer

Check the service profile association in UCS Manager

Question 14

Which tool provides a programmatic HTTP-based interface to execute CLI commands on Cisco Nexus switches and returns structured JSON data?

Accepted Answer

NX-API. NX-API (Option D) is the correct answer because it provides a programmatic HTTP/HTTPS-based interface that allows you to send CLI commands to Cisco Nexus switches and receive structured JSON (or XML) responses. This enables automation and integration without requiring an SSH session, directly fulfilling the question's requirement for an HTTP-based interface with structured JSON output.

Answer

Ansible

Answer

pyATS

Answer

Netmiko

Question 15

Refer to the exhibit. The interface fc1/1 is configured as an E_port. The connected switch also has an E_port configured. However, the interface shows an 'init' state. What is the most likely cause?

Accepted Answer

The speed on the remote switch interface is set to 8000 Mbps.. The 'init' state on an E_port indicates that the link is up but the port is still initializing the Exchange Link Parameters (ELP) and Exchange Switch Capabilities (ESC) protocols. If the remote switch interface speed is set to 8000 Mbps (8 Gbps) while the local interface is configured for a different speed (e.g., 4 Gbps or 16 Gbps), the speed negotiation will fail, preventing the E_port from transitioning to the 'online' state. Cisco MDS switches require matching speed settings on both ends of an E_port for successful initialization.

Answer

The domain ID is not configured on either switch.

Answer

The port VSAN on the local interface is different from the remote.

Answer

The remote switch interface is not configured as a trunk.
