300-410 Device Management — All Questions With Answers

A network engineer is troubleshooting a router that is not sending SNMP traps to the NMS server at 10.1.1.100. The SNMP configuration includes 'snmp-server enable traps' and 'snmp-server host 10.1.1.100 version 2c public'. The engineer can ping the NMS server from the router, and 'show snmp' indicates SNMP is enabled. What is the most likely cause of the missing traps?

Question 2mediummultiple choice

An engineer is troubleshooting a router that fails to write its running configuration to startup configuration using 'copy running-config startup-config'. The command returns 'Destination filename [startup-config]?' and then the prompt returns without error. 'show startup-config' shows an empty configuration. What is the most likely cause?

Question 3hardmultiple choice

A network engineer is troubleshooting a router that has been running for 200 days. The router experiences a sudden reboot, and after reload, the configuration is missing. 'show startup-config' returns 'startup-config is not present'. The engineer checks the boot variable: 'boot system flash:ios-image.bin'. What is the most likely cause of the configuration loss?

An engineer is troubleshooting a router that is not sending syslog messages to the syslog server at 192.168.1.10. The configuration includes 'logging host 192.168.1.10' and 'logging trap informational'. The engineer can ping the syslog server from the router. 'show logging' shows that the logging buffer is filling with messages. What is the most likely cause?

Question 5mediummultiple choice

A network engineer is troubleshooting a router that is not responding to ICMP echo requests from a management station at 10.10.10.1. The router has an ACL applied to the VTY lines that permits only 10.10.10.0/24. The engineer can telnet to the router from the management station. What is the most likely cause?

Question 6hardmultiple choice

An engineer is troubleshooting a router that is configured as an NTP client. The router's clock is not synchronizing with the NTP server at 192.168.1.1. 'show ntp status' shows 'clock is unsynchronized', and 'show ntp associations' shows the server as '.INIT.' with no reachability. The engineer can ping the NTP server. What is the most likely cause?

Question 7mediummultiple choice

What is the most likely cause?

Question 8hardmultiple choice

An engineer is troubleshooting a router that is configured to archive configurations to a TFTP server at 192.168.1.10.

The engineer notices that the archive is not being created after 'copy running-config startup-config'. What is the most likely cause?

Question 9hardmultiple choice

A network engineer is troubleshooting a router that is not allowing SSH connections from any management station. The router has 'ip domain-name example.com' and 'crypto key generate rsa' configured.

Question 33hardmultiple choice

A large enterprise network is experiencing intermittent loss of reachability to a loopback interface on Router R2 from Router R1. R1 has the following relevant configuration: router eigrp 100, network 10.0.0.0 0.255.255.255, summary-address 10.0.0.0 255.255.252.0 5. R2 shows: 'show ip eigrp topology all-links' includes 10.0.0.0/22 as a summary route via Null0, but the specific /32 loopback 10.0.1.1 is not in the topology table. What is the root cause?

Question 34hardmultiple choice

A network engineer redistributes OSPF routes into EIGRP on Router R1. After redistribution, Router R3, which is an EIGRP neighbor of R1, starts experiencing routing loops for the 192.168.1.0/24 network. R1 configuration: router eigrp 100, redistribute ospf 1 metric 10000 100 255 1 1500, route-map RM-OSPF-to-EIGRP. The route-map sets tag 100. R3 shows: 'show ip route 192.168.1.0' points to R1, but traceroute shows packets looping between R1 and R3. What is the root cause?

Question 35hardmultiple choice

A BGP speaker R1 is advertising a prefix 10.10.0.0/16 to its eBGP neighbor R2. R2 is also receiving the same prefix from another eBGP neighbor R3 with a lower local preference. R1 configuration: router bgp 100, neighbor 192.168.1.2 remote-as 200, neighbor 192.168.1.2 route-map SET-LP in. Route-map SET-LP sets local-preference 150. R2 shows: 'show ip bgp 10.10.0.0/16' shows two paths: one from R1 with local pref 150, and one from R3 with local pref 100. The best path is via R3. Why is the path from R1 not selected?

Question 36hardmultiple choice

Two routers R1 and R2 are connected via a FastEthernet link. OSPF is configured on both with network type broadcast. R1 shows: 'show ip ospf neighbor' lists R2 as FULL/DR. R2 shows: 'show ip ospf neighbor' lists R1 as FULL/BDR. However, pings between loopback interfaces on R1 and R2 fail intermittently. 'show ip route' on R1 shows the loopback of R2 as reachable via OSPF, but 'show ip ospf interface' on R1 shows the link as point-to-point. What is the root cause?

Question 37hardmultiple choice

An EIGRP network with routers R1, R2, and R3 is experiencing frequent Stuck-in-Active (SIA) events for the prefix 172.16.1.0/24. R1 is the successor, R2 is the feasible successor. R3 is a query originator. 'show ip eigrp topology 172.16.1.0/24' on R1 shows the route in active state. 'show ip eigrp interfaces' on R2 shows the link to R3 is up but with high packet loss. What is the root cause?

Question 38hardmultiple choice

A DMVPN network with hub R1 and spokes R2 and R3 is configured with mGRE and NHRP. Spoke-to-spoke tunnels fail to form. R1 configuration: interface Tunnel0, ip address 10.0.0.1 255.255.255.0, tunnel source GigabitEthernet0/0, tunnel mode gre multipoint, ip nhrp network-id 1, ip nhrp map multicast dynamic. R2 shows: 'show dmvpn' shows no dynamic sessions. R3 shows: 'show ip nhrp' shows no entries for R2. What is the root cause?

Question 39hardmultiple choice

An MPLS network with routers R1, R2, and R3 is experiencing label distribution failures. R1 and R2 are LDP neighbors, but R2 shows: 'show mpls ldp neighbor' shows R1 in state OPERATIONAL, but 'show mpls forwarding-table' shows no labels for prefixes from R3. R3 is connected to R2 via a different interface. R2 configuration: mpls ip on both interfaces. R1 shows: 'show mpls ldp bindings' includes prefixes from R3. What is the root cause?

Question 40hardmultiple choice

Network management traffic from a monitoring server to routers R1, R2, and R3 is being blocked intermittently. The monitoring server uses SNMP and SSH. R1 configuration: access-list 100 permit udp any any eq snmp, access-list

100 permit tcp any any eq 22, access-list 
100 deny ip any any, and 'ip access-group 100 in' on the management interface. R2 shows: 'show snmp' indicates SNMP is enabled. R3 shows: 'show ssh' indicates SSH is enabled. The monitoring server can reach R1 but not R2 or R3. What is the root cause?

Question 41hardmultiple choice

A VRF-aware network has VRF BLUE on routers R1 and R2. Routes are leaked between VRF BLUE and the global table on R1 using route-replicate. R2 shows: 'show ip route vrf BLUE' includes a route 10.10.10.0/24 learned via OSPF, but 'show ip route' (global) on R1 does not include this route. R1 configuration: ip vrf BLUE, rd 100:1, route-target export 100:1, route-target import 100:1, and 'route-replicate from vrf BLUE to global unicast 10.10.10.0 255.255.255.0'. What is the root cause?
