350-601 Practice Test 35 — 15 Questions

Question 1

Which FC port type is used for end-device connection in Fibre Channel fabric, and is typically found on a host bus adapter?

Accepted Answer

N-port. An N-port (Node Port) is the Fibre Channel port type used on end devices such as host bus adapters (HBAs) to connect to the fabric. It is the standard port on a node that communicates with an F-port on a switch. This is the port type typically found on an HBA.

Answer

NP-port

Answer

E-port

Answer

F-port

Question 2

A network engineer is configuring OSPF on a pair of Nexus 9000 switches acting as spine switches in a VXLAN fabric. The engineer needs to ensure that the spine switches do not become the DR for any VLAN. Which configuration should be applied?

Accepted Answer

Set ospf priority to 0 on the spine interfaces.. Setting the OSPF priority to 0 on the spine interfaces prevents the spine switches from participating in the DR/BDR election process, ensuring they never become the Designated Router (DR) for any VLAN. This is the standard method to suppress DR election on a multi-access network segment.

Answer

Configure passive-interface default under OSPF.

Answer

Set ospf network type to point-to-multipoint.

Answer

Set ospf priority to 255 on the spine interfaces.

Question 3

In an FCoE environment, a CNA presents a VN-port to the network. Which protocol is used to establish the virtual link between the VN-port and the FCoE switch's VF-port?

Accepted Answer

FIP. FIP (FCoE Initialization Protocol) is used to establish the virtual link between a VN-port (on the CNA) and a VF-port (on the FCoE switch). FIP performs discovery, fabric login, and fabric logout for FCoE devices, allowing the VN-port to obtain an FCID and become part of the Fibre Channel fabric. This is the correct protocol for virtual link establishment in FCoE.

Answer

ARP

Answer

LLDP

Answer

DHCP

Question 4

A storage administrator is troubleshooting a connectivity issue between a server and a storage array over Fibre Channel. The server is connected to an NPV edge switch, which uplinks to a core switch. The server's WWPN is registered in the zone, but the server cannot see the target. The administrator notices that the core switch does not see the server's WWPN in its FC name server database. What is the most likely cause?

Accepted Answer

The NPV edge switch does not register host WWPNs in the core fabric's name server; only the NP-port WWPN is registered. In NPV mode, the edge switch does not register the host WWPNs in the core fabric's name server; only the NP-port's WWPN is registered. Therefore, the core switch's name server will not show the server's WWPN, even though the server is zoned. This is expected behavior in NPV, and the server can still communicate with the target if zoning is correct on the core. The issue is likely a misunderstanding of NPV's registration behavior.

Answer

The host is using an incorrect FCID

Answer

The VSAN mismatch between edge and core switches

Answer

The zone set is not activated on the edge switch

Question 5

A data center engineer is configuring a Cisco UCS C-Series server with a hardware RAID controller. The server will host a critical database. The RAID controller supports RAID 0, 1, 5, 6, and 10. Which RAID level should be chosen to provide the best combination of performance and fault tolerance?

Accepted Answer

RAID 10. RAID 10 (striping of mirrors) provides the best combination of performance and fault tolerance for a critical database workload. It offers high read/write performance through striping and full redundancy via mirroring, allowing up to one disk failure per mirrored pair without data loss. This is ideal for a Cisco UCS C-Series server with a hardware RAID controller where both I/O throughput and availability are paramount.

Answer

RAID 6

Answer

RAID 5

Answer

RAID 0

Question 6

A network administrator needs to automate ACI configuration using a Python library that abstracts the APIC REST API. Which library should be used?

Accepted Answer

acitoolkit. The acitoolkit is a Python library that provides an abstraction layer over the APIC REST API. Cobra SDK is a lower-level Python SDK. cisco_nxapi is for Nexus, not ACI. Ansible is not a Python library.

Answer

cisco_nxapi

Answer

Ansible

Answer

Cobra SDK

Question 7

A network engineer wants to send NX-OS CLI commands via HTTP/HTTPS to a Nexus switch programmatically. Which API should be used?

Accepted Answer

NX-API CLI. NX-API CLI is the correct API for sending NX-OS CLI commands via HTTP/HTTPS. It allows network engineers to send CLI commands programmatically over HTTP/HTTPS and receive output in XML or JSON. NETCONF and RESTCONF are standards-based protocols that use YANG models and typically use SSH or HTTP/HTTPS, but they are not used for sending raw CLI commands. NX-API REST is for structured data operations, not for sending CLI commands.

Answer

NETCONF

Answer

NX-API REST

Answer

RESTCONF

Question 8

A UCS C-series server is deployed in a standalone environment. The administrator needs to update the server's firmware remotely. Which CIMC feature should be used?

Accepted Answer

Firmware Update page in CIMC. The CIMC (Cisco Integrated Management Controller) on a standalone UCS C-series server provides a web-based Firmware Update page that allows administrators to upload and apply firmware updates directly to the server components. This feature is specifically designed for remote firmware management without requiring an OS agent or external management software. Since the server is standalone (not managed by UCS Manager), the CIMC is the correct tool.

Answer

Virtual KVM

Answer

Virtual Media

Answer

UCS Manager

Question 9

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 is the centralized management platform for UCS B-Series blade servers and provides the firmware management interface for the entire UCS domain. It allows administrators to perform firmware upgrades on blades, IOMs, and fabric interconnects remotely through a single pane of glass. Firmware policies and host firmware packages are defined in UCS Manager and applied to service profiles, making it the correct tool for blade firmware upgrades.

Answer

HyperFlex Connect

Answer

Cisco IMC Supervisor

Answer

CIMC of the blade server

Question 10

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) is the BMC on standalone UCS C-series rack servers, providing out-of-band management, remote KVM, virtual media, and power control via its own dedicated management port. It operates independently of the host OS and is the correct interface for standalone C-series out-of-band configuration.

Answer

UCS Central

Answer

Cisco IMC Supervisor

Answer

UCS Manager

Question 11

An organization is migrating from traditional SNMP monitoring to model-driven telemetry on their Nexus 9000 switches. They have configured a telemetry destination using gRPC and have defined sensor paths for interface statistics. After several hours, the collector (a Linux server running Telegraf) reports no data received. The engineer verifies that the switch can reach the collector via ICMP. On the switch, 'show telemetry data collector details' indicates the destination is 'connected', but the 'last data sent' timestamp is several hours old. Which action should the engineer take next?

Accepted Answer

Verify that the sensor paths are correct and that the data is being generated. The 'show telemetry data collector details' output shows the destination is 'connected' and the switch can reach the collector, ruling out network or connectivity issues. The stale 'last data sent' timestamp indicates the telemetry process is running but no data is being published, which typically means the configured sensor paths are not producing data—either because the paths are incorrect, the MIB objects are not supported, or the interfaces are not generating the expected statistics. Option C is correct because verifying the sensor paths and ensuring data generation addresses the root cause without unnecessary changes or reboots.

Answer

Change the transport protocol from gRPC to HTTP

Answer

Reboot the switch to reset the telemetry process

Answer

Increase the telemetry sampling interval to reduce load

Question 12

Refer to the exhibit. The interface shows CRC errors. What is the most likely cause of these errors?

Accepted Answer

Faulty SFP or fiber cable.. CRC errors indicate that frames are being received with invalid checksums, which is typically caused by physical-layer issues such as a faulty SFP module or damaged fiber cable. These errors occur when the cyclic redundancy check computed by the receiver does not match the CRC appended by the sender, pointing to corruption during transmission. In Fibre Channel storage networks, a faulty SFP or cable is the most common root cause of CRC errors, as they directly affect signal integrity.

Answer

Insufficient buffer credits for the distance.

Answer

The port is configured as F port but should be E port.

Answer

Speed mismatch between the ports.

Question 13

Which two statements correctly describe VXLAN BUM traffic handling? (Choose two.)

Accepted Answer

Ingress replication sends unicast copies of the BUM traffic to each remote VTEP.. Option A is correct because with ingress replication the ingress VTEP itself replicates the BUM (broadcast, unknown unicast, multicast) frame and sends a separate unicast copy to each remote VTEP that has interested members, using the remote VTEP's IP as the outer destination. Option C is correct because the multicast-based method maps the VXLAN VNI to an underlay multicast group, and the ingress VTEP sends a single multicast-encapsulated frame that is delivered by the underlay to all VTEPs that have joined that group and need the traffic. Option B is wrong because BUM traffic is not dropped by default; it must be delivered to all relevant VTEPs via either ingress replication or multicast. Option D is wrong because ingress replication uses unicast copies, not a single multicast packet. Option E is wrong because multicast is only one of the two supported BUM distribution methods; ingress replication is an alternative and does not require multicast in the underlay.

Answer

BUM traffic is dropped by default.

Answer

Ingress replication sends a single multicast packet to all VTEPs.

Answer

Multicast is required for VXLAN BUM handling.

Question 14

An iSCSI storage array is configured to support multipath I/O (MPIO) for high availability. The administrator needs to configure the initiator to use multiple network paths. What must be ensured for MPIO to work correctly?

Accepted Answer

The initiator must have multiple network interfaces and the storage must support multiple connections to the same LUN.. For iSCSI MPIO to function, the initiator must have multiple network interfaces (or multiple IP addresses on separate subnets) and the storage array must be capable of accepting multiple simultaneous connections to the same LUN from that initiator. This allows the initiator to establish independent sessions over each path, and the MPIO driver load-balances I/O across them while providing failover if one path goes down.

Answer

CHAP authentication must be disabled for MPIO.

Answer

All paths must use the same IP address on the initiator.

Answer

The storage array must present each LUN with a different LUN ID on each path.

Question 15

Refer to the exhibit. A client connected to Ethernet1/2 cannot obtain an IP address via DHCP. What is the most likely cause?

Accepted Answer

The DHCP snooping trust configuration is missing on the server port. The client cannot obtain an IP address via DHCP because the DHCP server port (Ethernet1/1) is not configured as a DHCP snooping trusted port. By default, all ports are untrusted, and DHCP snooping drops all DHCP server responses (OFFER, ACK) received on untrusted ports. Configuring the port connecting to the DHCP server as trusted is required to allow these messages to reach the client.

Answer

The DHCP snooping information option is disabled

Answer

The DHCP server is on a different VLAN

Answer

IP source guard is enabled on the client port
