Answer: B
Explanation:
The OSPF adjacency between Router A and Router B is broken because Router A is configured with an OSPF network type of "broadcast," while Router B is configured with "point-to-multipoint." OSPF adjacency requires the network types to match on both sides.
NEW QUESTION # 62
Refer to the exhibit.
A company is evaluating multiple network management system tools. Trending graphs generated by SNMP data are returned by the NMS and appear to have multiple gaps. While troubleshooting the issue, an engineer noticed the relevant output. What solves the gaps in the graphs?
- A. Configure the CIR rate to a lower value that accommodates all the NMS tools
- B. Remove the class map NMS from being part of control plane policing.
- C. Separate the NMS class map in multiple class maps based on the specific protocols with appropriate CoPP actions
- D. Remove the exceed-rate command in the class map.
Answer: C
Explanation:
Reference:
https://tools.cisco.com/security/center/resources/copp_best_practices
The class-map NMS in the exhibit did not classify traffic into specific protocols so many packets were dropped. We should create some class-map to classify the receiving traffic. It is also a recommendation of CoPP/CPP policy:
"Developing a CPP policy starts with the classification of the control plane traffic. To that end, the control plane traffic needs to be first identified and separated into different class maps."

NEW QUESTION # 65
Refer to the exhibit. A network administrator is troubleshooting an authentication failure issue during login into R2 using a RADIUS server user account. The network administrator can ping the RADIUS server, but the user access to SSH is denied on R2. Which action resolves the issue?
- A. Enable AAA authorization to allow SSH connections.
- B. Modify the aaa command to replace TACACS+ with RADIUS.
- C. Remove "local" from the aaa authentication command.
- D. Configure the username in RADIUS server database.
Answer: D
Explanation:
The configuration on R2 specifies that user authentication is done using RADIUS first, then TACACS+, and finally local as a fallback. The RADIUS server is reachable (ping succeeds), and the AAA authentication method is correct.
If the user credentials do not exist in the RADIUS server's user database, authentication will fail, and unless TACACS+ or local fallback is reachable and valid, access will be denied. Adding the appropriate user account (with correct credentials) on the RADIUS server resolves the SSH login issue.
NEW QUESTION # 66
Refer to the exhibit.

NEW QUESTION # 67
In which two ways does the IPv6 First-Hop Security Binding Table operate? (Choose two.)
- A. by storing hashed keys for IPsec tunnels for the built-in IPsec features
- B. by the recovery mechanism to recover the binding table in the event of a device reboot
- C. by IPv6 HSRP to make sure neighbors are authenticated before being used as gateways
- D. by IPv6 routing protocols to securely build neighborships without the need of authentication
- E. by various IPv6 guard features to validate the data link layer address
Answer: B,E
Explanation:
Overview of the IPv6 First-Hop Security Binding Table
A database table of IPv6 neighbors connected to the device is created from information sources such as NDP snooping. This database, or binding table, is used by variousIPv6 guard features to validate the link-layer address (LLA), the IPv4 or IPv6 address, and the prefix binding of the neighbors to prevent spoofing and redirect attacks.
IPv6 First-Hop Security Binding Table Recovery MechanismThe IPv6 first-hop security binding table recovery mechanism enables the binding table to recover in the event of a device reboot.

An engineer must filter incoming EIGRP updates to allow only a set of specific prefixes. The distribute list is tested, and it filters out all routes except network 10.10.10.0/24. How should the engineer temporarily allow all prefixes to be learned by the routers again without adjusting the existing access list?
- A. A permit any statement should be added before completing the ACL with the required prefixes and then the permit any statement can be removed.
- B. A continue statement should be added within the permit 10 statement before completing the ACL with the required prefixes, and then the continue statement can be removed.
- C. A permit 20 statement should be added before completing the ACL with the required prefixes, and then the permit 20 statement can be removed.
- D. An extended access list must be used instead of a standard access list to accomplish the task

NEW QUESTION # 72
Refer to the exhibit.
An engineer configures DMVPN and receives the hub location prefix of 10.1.1.0724 on R2 and R3 The R3 prefix of 10 1.3.0/24 is not received on R2. and the R2 prefix 10.1,2.0/24 is not received on R3. Which action reserves the issue?
- A. There is no spoke-to-spoke connection DMVPN configuration should be modified with a manual neighbor relationship configured between R2 and R3 and confirmed bb use of the show ip eigrp neighbor command.
- B. Split horizon prevents the routes from being advertised between spoke routers it should be disabled with the no ip split-horizon eigrp 10 command on the Gi0/0 interface of R1.
- C. There is no spoke-to-spoke connection DMVPN configuration should be modified to enable a tunnel connection between R2 and R3 and neighbor relationship confirmed by use of the show ip eigrp neighbor command
- D. Split horizon prevents the routes from being advertised between spoke routers it should be disabled with the command no ip split-horizon eigrp 10 on the tunnel interface of R1
Answer: D
Explanation:
In this topology, the Hub router will receive advertisements from R2 Spoke router on its tunnel interface. The problem here is that it also has a connection with R3 Spoke on that same tunnel interface. If we don't disable split-horizon, then the Hub will not relay routes from R2 to R3 and the other way around. That is because it received those routes on the same interface tunnel and therefore it cannot advertise back out that same interface (split-horizon rule). Therefore we must disable splithorizon on the Hub router to make sure the Spokes know about each other.
NEW QUESTION # 73
Refer to the exhibit.
An engineer is troubleshooting BGP on a device but discovers that the clock on the device does not correspond to the time stamp of the log entries. Which action ensures consistency between the two times?
- A. Make sure that the clock on the device is synchronized with an NTP server.
- B. Configure the service timestamps log uptime command in global configuration mode.
- C. Configure the logging clock synchronize command in global configuration mode.
- D. Configure the service timestamps log datetime localtime command in global configuration mode.
Answer: D
Explanation:

/reference/yr39xr12k_chapter4.html#wp1784026936
By default, syslog and debug messages are stamped by UTC, regardless of the time zone that device configured. You should append localtime key word to "service timestamp {log | debug} datetime msec" global command to change that behavior.

Refer to the exhibit. The Los Angeles and New York routers are receiving routes from Chicago but not from each other. Which configuration fixes the issue?
- A. Interface Tunnel1tunnel mode Ipsec Ipv4
- B. Interface Tunnel1no ip split-horizon eigrp 111
- C. Interface Tunnel1tunnel protection ipsec profile IPSec-PROFILE
- D. Interface Tunnel1Ip next-hop-self elgrp 111
Answer: B
Explanation:
In this topology, Chicago router (Hub) will receive advertisements from Los Angeles (Spoke1) router on its tunnel interface. The problem here is that it also has a connection with New York (Spoke2) on that same tunnel interface. If we don't disable EIGRP split-horizon, then the Hub will not relay routes from Spoke1 to Spoke2 and the other way around. That is because it received those routes on interface Tunnel1 and therefore it cannot advertise back out that same interface (splithorizon rule). Therefore we must disable split-horizon on the Hub router to make sure the Spokes know about each other.
