Free 300-410: Implementing Cisco Enterprise Advanced Routing and Services (ENARSI) Exam Questions and Answers
Implementing Cisco Enterprise Advanced Routing and Services (ENARSI) is exam 300-410, part of Cisco certifications. In Cisco's current scheme the first digit gives the level: 100 is entry, 200 associate, 300 the CCNP concentration exams, 350 the CCNP core exams that also qualify you for CCIE, 500 specialist and 700 the unproctored sales exams. Older codes such as 400-, 640- and 642- predate the February 2020 restructure, when every CCNA track was collapsed into one exam and CCNP moved to a core-plus-concentration model.

Question #1
A newly installed spoke router is configured for DMVPN with the ip mtu 1400 command. Which configuration allows the spoke to use fragmentation with the maximum negotiated TCP MTU over GRE?
Please select an optionIncorrectCorrect answer: A
With ip mtu 1400 the TCP MSS must be clamped to 1360 (1400 minus 40 bytes of IP/TCP headers) using ip tcp adjust-mss, and crypto ipsec fragmentation after-encryption lets the router fragment oversized packets after IPsec encapsulation.
Was this answer correct?Question #2
Refer to the exhibit. The Customer Edge router (AS 65500) wants to use ASC100 as the preferred ISP for all external routes. This configuration failed to send routes to AS 100 as the preferred path. Which set of configuration resolves the issue?
Please select an optionIncorrectCorrect answer: B
Was this answer correct?Question #3
An engineer notices that R1 does not hold enough log messages to identify the root cause during troubleshooting. Which command resolves this issue?
Please select an optionIncorrectCorrect answer: B
The buffer must be both larger and less restrictive: logging buffered 16000 informational is a global configuration command that enlarges the buffer and lowers the severity threshold so detailed messages are retained. Critical level would still discard most troubleshooting output.
Was this answer correct?Question #4
Which technique removes the outermost label of an MPLS-tagged packet before the packet is forwarded to an adjacent LER?
Please select an optionIncorrectCorrect answer: D
Penultimate hop popping has the second-to-last LSR remove the outermost label before forwarding to the egress LER, saving that router a lookup. Explicit-null keeps a label with value 0 instead of popping it.
Was this answer correct?Question #5
Refer to the exhibit. The R1 OSPF neighbor is not receiving type 5 external LSAs for 132.108.2.0/24 and 132.108.3.0/24 networks. Which configuration command resolves the issue?
Please select an optionIncorrectCorrect answer: B
The wildcard 0.0.3.255 matches 132.108.0.0 through 132.108.3.255, so it covers both 132.108.2.0/24 and 132.108.3.0/24 and allows the redistribution of those external routes. A 0.0.1.255 wildcard stops at 132.108.1.255.
Was this answer correct?Question #6
Refer to the exhibit. R1 is configured with uRPF, and ping to R1 is failing from a source present in the R1 routing table via the GigatxtEthernet 0/0 interface. Which action resolves the issue?
Please select an optionIncorrectCorrect answer: B
Strict uRPF drops the packet because the best return path to that source is not the interface the packet arrived on, which is normal with asymmetric routing. Loose mode only requires the source to exist in the routing table, so the ping succeeds.
Was this answer correct?Question #7
Refer to the exhibit. An engineer must configure a per VRF for TACACS+ for company A. Which configuration on RTG-1 accomplishes the task?
Please select an optionIncorrectCorrect answer: A
Was this answer correct?Question #8
A newly installed router starts establishing an LDP session from another MPLS router to which it is not directly connected. Which LDP message type responds by target router to the initiating router using UDP protocol?
Please select an optionIncorrectCorrect answer: C
A non-directly connected LSR is reached with targeted (extended) discovery, so the target router answers the initiating router with an extended discovery hello sent in UDP to port 646. Session messages only follow later over TCP once discovery succeeds.
Was this answer correct?Question #9
What is an MPLS LDP targeted session?
Please select an optionIncorrectCorrect answer: C
A targeted LDP session is a label distribution session built with unicast targeted hellos to a neighbor that is not directly connected, such as for AToM or session protection. Ordinary link sessions use multicast hellos between directly connected LSRs.
Was this answer correct?Question #10
Refer to the exhibit. During ISP router maintenance, the network produced many alerts because of the flapping interface. Which configuration on R1 resolves the issue?
Please select an optionIncorrectCorrect answer: A
