Q191. Which two are features of DMVPN? (Choose two.)
A. It does not support spoke routers behind dynamic NAT.
B. It requires IPsec encryption.
C. It only supports remote peers with statically assigned addresses.
D. It supports multicast traffic.
E. It offers configuration reduction.
Answer: D,E
Explanation:
DMVPN Hub-and-spoke deployment model: In this traditional topology, remote sites (spokes) are aggregated into a headend VPN device at the corporate headquarters (hub). Traffic from any remote site to other remote sites would need to pass through the headend device. Cisco DMVPN supports dynamic routing, QoS, and IP Multicast while significantly reducing the configuration effort.

Q192. External EIGRP route exchange on routers R1 and R2 was failing because the routers had duplicate router IDs. You changed the eigrp router-id command on R1, but the problem persists. Which additional action must you take to enable the routers to exchange routes?
A. Change the corresponding loopback address.
B. Change the router ID on R2.
C. Reset the EIGRP neighbor relationship.
D. Clear the EIGRP process.
Answer: D
Q193. When the BGP additional-paths feature is used, what allows a BGP speaker to differentiate between the different available paths?
A. The remote BGP peer prepends its own next-hop address to the prefix.
B. A unique path identifier is encoded into a dedicated field to the NLRI.
C. A route distinguisher is appended to the prefix by the receiving BGP speaker.
D. The additional path information is encoded in an extended community.
Answer: B
Q194. Which two pieces of information does RTCP use to inform endpoint devices about the RTP flow? (Choose two.)
A. the transmitted octet
B. the lost packet count
C. session control function provisioning information
D. the CNAME for session participants
E. the authentication method
F. MTU size changes in the path of the flow
Answer: A,B
Explanation:
RTCP transports statistics for a media connection and information such as transmitted octet and packet counts, packet loss, packet delay variation, and round-trip delay time. An application may use this information to control quality of service parameters, perhaps by limiting flow, or using a different codec.

Q199. Which three statements about VTP version 3 are true? (Choose three.)
A. It supports other databases in addition to VLAN.
B. It supports VLANs up to 4095.
C. It supports the synchronization of switch configuration templates between switches in the domain.
D. It supports the transfer of information about private VLAN structures.
E. It supports the transfer of PVST+ configuration information.
F. It supports RSTP.
Answer: A,B,D
Explanation:
Much work has gone into improving the usability of VTP version 3 in three major areas:
. The new version of VTP offers better administrative control over which device is allowed to update other devices' view of the VLAN topology. The chance of unintended and disruptive changes is significantly reduced, and availability is increased. The reduced risk of unintended changes will ease the change process and help speed deployment.
. Functionality for the VLAN environment has been significantly expanded. Two enhancements are most beneficial for today's networks:
– In addition to supporting the earlier ISL VLAN range from 1 to 1001, the new version supports the whole IEEE 802.1Q VLAN range up to 4095.
– In addition to supporting the concept of normal VLANs, VTP version 3 can transfer information regarding Private VLAN (PVLAN) structures.
. The third area of major improvement is support for databases other than VLAN (for example, MST).

Q200. Which BGP aggregate address configuration advertises only the aggregate address, with attributes inherited from the more specific routes?
A. summary-only as-set
B. as-set
C. summary
D. summary-only
Answer: A
Explanation:
Example:
router bgp 300
neighbor 2.2.2.2 remote-as 100
neighbor 3.3.3.3 remote-as 200
neighbor 4.4.4.4 remote-as 400
aggregate-address 160.0.0.0 255.0.0.0 summary-only as-set
!--- With the as-set configuration command, the aggregate
!--- inherits the attributes of the more-specific routes.
