Question 2

A customer is running an mGRE DMVPN tunnel over WAN infrastructure between hub and spoke sites. The existing configuration allows NHRP to add spoke routers automatically to the multicast NHRP mappings. The customer is migrated the network from IPv4 to the IPv6 addressing scheme for those spokes' routers that support IPv6 and can run DMVPN tunnel over the IPv6 network. Which configuration must be applied to support IPv4 and IPv6 DMVPN tunnel on spoke routers?

ATunnel mode ipv6ip 6to4

BTunnel mode ipv6ip isatap

CTunnel mode ipv6ip auto-tunnel

DTunnel mode ipv6ip 6rd

Answer : C

Question 3

no ip address

interface Server0/0/0.9 multipoint

ip address 10.1.1.1 255.255.255.248

ip split-horizon eigrp 1

Which action resolves the issue?

AEnable poison reverse

CDisable poison reverse

DDisable split horizon

Answer : D

Question 4

The last line shows us the reason, which is ''Invalid AUTHEN packet (check keys)'' so the most likely

cause of this problem is key mismatch.

Question 5

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?

ARemove the access list from the interface GigabrtEthernet 0/0

BModify the uRPF mode from strict to loose

CEnable Cisco Express Forwarding to ensure that uRPF is functioning correctly

DAdd a floating static route to the source on R1 to the GigabitEthernet 0/1 interface

Answer : B

Aip tcp adjust-mss 1360crypto ipsec fragmentation after-encryption

Bip tcp adjust-mtu 1360crypto ipsec fragmentation after-encryption

Cip tcp adjust-mss 1360crypto ipsec fragmentation mtu-discovery

Dip tcp adjust-mtu 1360crypto ipsec fragmentation mtu-discovery
