300-615 Troubleshooting Cisco Data Center Infrastructure (DCIT) Questions and Answers

A server administrator attempts to change the Cisco IMC KVM certificate to one signed by a private CA, but the certificate is not being accepted. What can cause this process to fail?

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?

Refer to the exhibit.

A network engineer has connected the Nexus switch management port to the Internet using DHCP to allow the Guest shell running on the switch to download Python packages. The engineer can ping google.com successfully from the Nexus switch, but the Guest shell failed to download any Python packages. Which action resolves the problem?

Refer to the exhibit.

The EEM script fails to send an SNMP trap when a user attempts to enter configuration mode. Which configuration is missing from the script?

Refer to the exhibit The EEM applet must generate a syslog message whena BGP adjacency faps. This message must be displayed to the console of the switch. However, when a BGP adjacency failure is simulated, no syslog message is displayed. Which action resolves the issue?

Refer to the exhibit.

The HSRP configuration in the exhibit fails to function. Which action resolves this issue?

A network engineer is implementing the Cisco ACI Fabric and notices that the Leaf-1 switch is registered, has

an assigned name, but is displayed as inactive in the APIC. After further investigation, it became clear that the

leaf switch was recently moved from another Cisco ACI environment. Which action resolves the problem?

Refer to the exhibit.

Partial configuration from N9K-1 and N9K-2 is included. The client has two WANs connected.

• WAN-1 is for normal business-day activities.
• WAN-2 is for server backups during nonworking hours of 1:00 a.m. to 5:00 a.m. daily.

The client says that at the scheduled time for backup, the data center server failed to use the WAN-2 link to back up the servers to the cloud backup system. What is the solution to this problem?

Refer to the exhibit.

A certificate is implemented on the security configuration on the Cisco ACI controller. A customer receives a "Connection Not Secure" error in a browser every time the customer logs in to the Cisco APIC GUI. Which action resolves the issue?

Refer to the exhibit.

After an unexpected reload of the Cisco Nexus 9000 Series Switch, the network administrator noticed that one of the Software Maintenance Upgrades (SMU) images is inactive. The engineer must ensure that the package remains active after the switch is reloaded in the future. Which action accomplishes this goal?

Refer to the exhibit. A network engineer creates an EEM script to trigger an SNMP notification when a user enters configuration mode, but the trap is not received when the condition is met. Which action resolves the issue?

A customer configures HSRP between two data centers that are interconnected with OTV. The configuration succeeds, but traffic between two ESXi virtual hosts on the same site is routed suboptimally through the OTV overlay. Which two actions optimize the traffic? (Choose two.)

A network engineer must connect a Cisco UCS Fabric Interconnect cluster to the Cisco ACI. VMware ESXi hypervisors have been installed on Cisco UCS blades and a VMware VMM domain has been configured. However, virtual machines fail to reach their default gateway in the Cisco ACI Fabric. The engineer investigates the issue and notices that the VMware Distributed Switch (VDS) teaming policy is set to "Route based on IP hash". Which action resolves the issue?

One of Cisco Nexus Series interfaces has become errdisabled with the error message “DCX-No ACK in 100 PDUs”. What is the cause of this error?

A mission-critical server is connected to site A. Connectivity to this server is lost from site B because the MAC route is missing in the OTV VDC of the Nexus 7000 in site B due to MAC aging. Which action allows the flooding of the unknown unicast MAC on the Nexus 7000 in the OTV VDC?

Refer to the exhibit.

The EEM script overrides all events in the system policy. What should be added to the script to resolve the issue?

Refer to the exhibit. A network engineer must use BGP to route IPv4 and IPv6 routes between R1 and R2. The IPv4 addresses are exchanged as expected between the routers through BGP. The routers have reached an Established BGP state. However, the IPv6 routes from R2 fail to show in the routing table of R1. Which action resolves the issue?

Refer to the exhibit.

A client configures an upgrade of its Cisco Nexus switches that are connected to the Cisco ACI controller, such that the switches are upgraded one at a time. After the upgrade is run, it is discovered that both Cisco Nexus switches were upgraded simultaneously. Which two actions ensure that the switches upgrade one at a time? (Choose two.)

An engineer must replace a failed memory on a Cisco UCS B-Series Blade Server. After the replacement was done, the server has a “resolve slot” warning. Which server maintenance action resolves the issue?

Refer to an exhibit.

An engineer is troubleshooting an upgrade failure on a switch. Which action resolves the issue?

Refer to the exhibit.

An engineer monitors a Cisco UCS server logs and discovers a blade discovery issue. Which procedure resolves the issue?

Refer to the exhibit.

Cisco UCS Manager is being upgraded using the Auto Install feature, but the FSM fails. Which action resolves the issue?
