Question No : 1
Which Cisco VPN technology can use multipoint tunnel, resulting in a single GRE tunnel interface on the hub, to support multiple connections from multiple spoke devices?
A.DMVPN
B.GETVPN
C.Cisco Easy VPN
D.FlexVPN

正解: A
Explanation:
An mGRE tunnel inherits the concept of a classic GRE tunnel but an mGRE tunnel does not require a unique tunnel interface for each connection between Hub and spoke like traditional GRE. One mGRE can handle multiple GRE tunnels at the other ends. Unlike classic GRE tunnels, the tunnel destination for a mGRE tunnel does not have to be configured; and all tunnels on Spokes connecting to mGRE interface of the Hub can use the same subnet.

Question No : 2
Which protocol is used in a DMVPN network to map logical IP address to physical IP addresses?
A.BGP
B.LLDP
C.EIGRP
D.NHRP

正解: D
Explanation:
Next Hop Resolution Protocol (NHRP), defined in RFC 2332, is a Layer 2 address resolution protocol and cache, like Address Resolution Protocol (ARP). NHRP is used by a branch router connected to a non-broadcast, multi-access (NBMA) sub-network to determine the IP address of the “NBMA next hop”; in this case, the headend router or the destination IP address of another branch router.
NHRP is used to map tunnel IP addresses to “physical” or “real” IP addresses, used by endpoint routers. It resolves private addresses (those behind mGRE and optionally IPSEC) to a public address. NHRP is layer 2 resolution protocol and cache, much like Address Resolution Protocol (ARP) or Reverse ARP (Frame Relay).

Question No : 3
Which two methods use IPsec to provide secure connectivity from the branch office to the headquarters office? (Choose two.)
A.DMVPN
B.MPLS VPN
C.Virtual Tunnel Interface (VTI)
D.SSL VPN
E.PPPoE

正解: AC
Explanation:
IP security (IPsec) virtual tunnel interfaces (VTIs) provide a routable interface type for terminating IPsec tunnels and an easy way to define protection between sites to form an overlay network. IPsec VTIs simplify configuration of IPsec for protection of remote links, support multicast, and simplify network management and load balancing.

Question No : 4
An engineer is trying to copy an IOS file from one router to another router by using TFTP.
Which two actions are needed to allow the file to copy? (Choose two.)
A.Configure the TFTP authentication on the source router with the tftp-server authentication local command.
B.Configure a user on the source router with the username tftp password tftp command.
C.Enable the TFTP server on the source router with the tftp-server flash: command.
D.TFTP is not supported in recent IOS versions, so an alternative method must be used.
E.Copy the file to the destination router with the copy tftp: flash: command

正解: ACE
Explanation:
Below are the steps to follow for copying the Cisco IOS software image from a router acting as TFTP server to another router.

Question No : 5
Which statement about IPv6 RA Guard is true?
A.It does not offer protection in environments where IPv6 traffic is tunneled
B.It cannot be configured on a switch port interface in the ingress direction.
C.Packets that are dropped by IPv6 RA Guard cannot be spanned.
D.It is not supported in hardware when TCAM is programmed.

正解: A
Explanation:
Restrictions for IPv6 RA Guard
+ The IPv6 RA Guard feature does not offer protection in environments where IPv6 traffic is tunneled.
+ This feature is supported only in hardware when the ternary content addressable memory (TCAM) is programmed.
+ This feature can be configured on a switch port interface in the ingress direction.
+ This feature supports host mode and router mode.
+ This feature is supported only in the ingress direction; it is not supported in the egress direction.
+ This feature is not supported on EtherChannel and EtherChannel port members.
+ This feature is not supported on trunk ports with merge mode.
+ This feature is supported on auxiliary VLANs and private VLANs (PVLANs). In the case of PVLANs, primary VLAN features are inherited and merged with port features.
+ Packets dropped by the IPv6 RA Guard feature can be spanned.
+ If the platform ipv6 acl icmp optimize neighbor-discovery command is configured, the IPv6 RA Guard feature cannot be configured and an error message will be displayed. This command adds default global Internet Control Message Protocol (ICMP) entries that will override the RA guard ICMP entries.

Question No : 6
Which statement about MPLS LDP router ID is true?
A.The force keyword changes the router ID to the specific address causing any impact.
B.The loopback with the highest IP address is selected as the router I
C.If not configured, the operational physical interface is chosen as the router ID even if a loopback is configured.
D.If MPLS LDP router ID must match the IGP router I
