Free Troubleshooting Cisco Data Center Infrastructure Exam 300-615 Exam Practice Test

An engineer is implementing a new BGP peering in their new data center. The engineer set up the BGP session that peers with the remote end. As soon as the BGP peers attempt to exchange routing prefixes, one of the BGP peers drops the connection. After reviewing the configuration, the engineer reviews the logging messages. The engineer discovers that the router is missing keepalives from the remote end and terminates the session. Which action resolves the issue?

• Set the bgp transport path-mtu-discovery attribute on both peers
• Set the higher values for the BGP keepalive and hold-down timers on both peers
• Configure the matching BGP AS numbers between the peers
• Configure the matching BGP passwords between the peers

An engineer is troubleshooting a fabric discovery failure. Which two requirements must an engineer verify about switch connectivity to solve the problem? (Choose two.)

• A Cisco APIC must be attached to a spine node only.
• A Cisco APIC must be attached to leaf nodes.
• Spine nodes must connect to other spine nodes.
• A Cisco APIC must be dual-attached to two separate spine nodes.
• Leaf nodes must connect to spine nodes only.

A request to activate the port security database is rejected. Which action do you perform to investigate the cause of the issue?

• Enable the auto-learning feature.
• Use the force option to identify rejected devices.
• Find conflicting entries between the active and configuration databases.
• Verify that devices are fully attached to the active database.

The external routes fail to propagate to leaf switches in Cisco ACI fabric Which two actions resolve the issue? (Choose two.)

• Enable the VTEP pool in the fabric
• Assign an MP-BGP AS number to the fabric.
• Specify the spine nodes as route reflectors
• Associate the correct contract to the L30ut.
• Configure an MP-BGP area.

You have an ACI environment with three APICs, two spine switches, and four-leaf switches. You wipe and reboot all APICs first then leaf and spine switches one-by-one and successfully go through the Initial Setuo dialogue on the APIC 1 CIMC KVM console. When you log in to the APIC1 WebGUI, you notice that you do not see any directly connected leaf switches being discovered under Fabric > Inventory > Fabric Membership. What is the cause of the issue?

• The leaf nodes were not erased properly, which caused a fabric parameters mismatch with the APIC1.
• Rebooting the APICs and the leaf and spine switches after wiping them is not required.
• You forgot to enter the TEP Pool value during the Initial Setup dialogue on APIC1.
• The same Fabric Name value should be used before after wiping all devices.

A network engineer notices a sudden interruption to the HSRP adjacency between the switches. The packet loss is reported on the servers for which the default gateway is set as the virtual IP of the HSRP. AII servers onthe VL AN can exchange ping messages. Which configuration set must be applied on the HSRP peers to resolve the adjacency issue?

A network administrator attempts to install an application in the Cisco NX-OS Guest shell and receives an error that there is not enough space on the disk. Which command must the administrator run to increase the disk space available in the Guest shell?

• guestshell growdisk rootfs [size-in-MB]
• guestshell pvextend rootfs [size-in-MB]
• guestshell resize rootfs [size-in-MB]
• guestshell resize2fs rootfs [size-in-MB]

After upgrading a client's fabric interconnect to the latest version, an engineer discovers that the appliance has lost its entire configuration. Which two locations should an engineer check to confirm that the appliance had backed up the configuration prior to the upgrade in order to retrieve the lost configuration? (Choose two.)

• Equipment FSM page, InternalBackup stage
• Service profiles page, InternalBackup stage
• Admin page, PollInternalBackup stage
• Equipment FSM page, PollInternalBackup stage
• Admin page, InternalBackup stage.

An IOM fails during a firmware upgrade and is unresponsive. Which action recovers the module?

• Restore UCSM configuration from backup.
• Roll back to the previous firmware.
• Use AutoInstall to reinstall the firmware.
• From the peer IOM, reset the faulty module.

Refer to the exhibit A network administrator must provide Bash shell access to the support team for all of the Cisco Nexus 9000 Series Switches. The newly created user that is named 'bashusers' fails to access the Bash shell. Which action resolves the issue?

• Associate bashusers with the Cisco NX-OS vdc-admin role and activate the nxapi feature.
• Associate bashusers with the Cisco NX-OS dev-ops role and activate the bash-shell feature.
• Associate bashusers with the Cisco NX-OS network-admin role and activate the guestshell feature.
• Associate bashusers with the Cisco NX-OS network-operator role and activate the bash-shell feature.
