Question 1

Explanation

NAT64 provides communication between IPv6 and IPv4 hosts by using a form of network address translation (NAT). NAT64 requires a dedicated prefix, called NAT64 prefix, to recognize which hosts need IPv4-IPv6 translation. NAT64 prefix can be a Network-specific prefix (NSP), which is configured by a network administrator, or a well-known prefix (which is 64:FF9B::/96). When a NAT64 router receives a packet which starts with NAT64 prefix, it will proceed this packet with NAT64.

NAT64 is not as simple as IPv4 NAT which only translates source or destination IPv4 address. NAT64 translates nearly everything (source & destination IP addresses, port number, IPv4/IPv6 headers… which is called a session) from IPv4 to IPv6 and vice versa. So NAT64 “modifies session during translation”.

Question 2

Explanation

The order of the BGP states is: Idle -> Connect -> (Active) -> OpenSent -> OpenConfirm -> Established

+ Idle: No peering; router is looking for neighbor. Idle (admin) means that the neighbor relationship has been administratively shut down.
+ Connect: TCP handshake completed.
+ Active: BGP tries another TCP handshake to establish a connection with the remote BGP neighbor. If it is successful, it will move to the OpenSent state. If the ConnectRetry timer expires then it will move back to the Connect state. Note: Active is not a good state.
+ OpenSent: An open message was sent to try to establish the peering.
+ OpenConfirm: Router has received a reply to the open message.
+ Established: Routers have a BGP peering session. This is the desired state.

Question 3

Explanation

The Challenge Handshake Authentication Protocol (CHAP) verifies the identity of the peer by means of a three-way handshake. These are the general steps performed in CHAP:
1) After the LCP (Link Control Protocol) phase is complete, and CHAP is negotiated between both devices, the authenticator sends a challenge message to the peer.
2) The peer responds with a value calculated through a one-way hash function (Message Digest 5 (MD5)).
3) The authenticator checks the response against its own calculation of the expected hash value. If the values match, the authentication is successful. Otherwise, the connection is terminated.

This authentication method depends on a “secret” known only to the authenticator and the peer. The secret is not sent over the link. Although the authentication is only one-way, you can negotiate CHAP in both directions, with the help of the same secret set for mutual authentication.

Reference: http://www.cisco.com/c/en/us/support/docs/wan/point-to-point-protocol-ppp/25647-understanding-ppp-chap.html

For more information about CHAP challenge please read our PPP tutorial.

Question 5

Explanation

AAA offers different solutions that provide access control to network devices. The following services are included within its modular architectural framework:
+ Authentication – The process of validating users based on their identity and predetermined credentials, such as passwords and other mechanisms like digital certificates. Authentication controls access by requiring valid user credentials, which are typically a username and password. With RADIUS, the ASA supports PAP, CHAP, MS-CHAP1, MS-CHAP2, that means Authentication supports encryption.
+ Authorization – The method by which a network device assembles a set of attributes that regulates what tasks the user is authorized to perform. These attributes are measured against a user database. The results are returned to the network device to determine the user’s qualifications and restrictions. This database can be located locally on Cisco ASA or it can be hosted on a RADIUS or Terminal Access Controller Access-Control System Plus (TACACS+) server. In summary, Authorization controls access per user after users authenticate.
+ Accounting – The process of gathering and sending user information to an AAA server used to track login times (when the user logged in and logged off) and the services that users access. This information can be used for billing, auditing, and reporting purposes.

Question 6

Question 7

Question 8

Explanation

NAT64 provides communication between IPv6 and IPv4 hosts by using a form of network address translation (NAT). There are two different forms of NAT64, stateless and stateful:

+ Stateless NAT64: maps the IPv4 address into an IPv6 prefix. As the name implies, it keeps no state. It does not save any IP addresses since every v4 address maps to one v6 address. Stateless NAT64 does not conserve IP4 addresses.
+ Stateful NAT64 is a stateful translation mechanism for translating IPv6 addresses to IPv4 addresses, and IPv4 addresses to IPv6 addresses. Like NAT44, it is called stateful because it creates or modifies bindings or session state while performing translation (1:N translation). It supports both IPv6-initiated and IPv4-initiated communications using static or manual mappings. Stateful NAT64 converses IPv4 addresses.

NPTv6 stands for Network Prefix Translation. It’s a form of NAT for IPv6 and it supports one-to-one translation between inside and outside addresses

    @RPM

    ip dhcp relay information option –> add suboption and the remote ID suboption

    ip dhcp relay information check –> Verify relay information option (in forwarded BOOTREPLY)

    ip dhcp relay information policy …… –> Define reforwarding rules (for a DHCP relay agent)

    ip dhcp relay information subscriber-id –> enable a service provider to add a unique ID

    ip dhcp relay information –> configured in global configuration mode applies to all interface

    New Drag&Drop with PPP on Frame Realy

    I found a example like the exam here : https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/wan_frly/configuration/15-mt/wan-frly-15-mt-book/wan-pppofr.html#GUID-1CB0E01F-B4AF-4CF6-9863-D116BBD13C2B. I was the DTE exercise

    exercise

    interface serial 0
    ” BLANK ”
    encapsulation frame-relay
    ” BLANK ” — I know there is 2 blank on interface serial 0 but I don’t remember the existing command and the blank

    #about sub-interface (it’s write like that in the exam)
    ” BLANK ”
    ” BLANK ”

    interface Virtual-Template1
    ip unnumbered ethernet 0
    ” BLANK ”

    Possibility
    D&D 1 : ” no ip address ”
    D&D 2 : ” interface serial 0/0.1 point-to-point ”
    D&D 3 : ” interface serial 0/0.100 ”
    D&D 4 : ” frame-relay interface-dlci 32 ppp virtual-template1 ”
    D&D 5 : ” another think about virtual-template ”
    D&D 6 : ” ip unnumbered ethernet 0 ”
    D&D 7 : ” ppp authentication chap ”
    D&D 8 : ” frame-relay lmi-type ansi ”

    Answer
    interface serial 0
    ” no ip address ”
    encapsulation frame-relay
    ” frame-relay lmi-type ansi ”
    !
    ” interface serial 0.1 point-to-point ”
    ” frame-relay interface-dlci 32 ppp virtual-template1 ”
    !
    interface Virtual-Template1
    ip unnumbered ethernet 0
    ” ppp authentication chap ”

    I hope it’s will help you :)

    With regards to Q7 – see this link http://www.ciscopress.com/articles/article.asp?p=170744&seqNum=5

    and it informed that:

    “RADIUS combines authentication and authorization and separates accounting, thus allowing less flexibility in implementation.”

    Sorlags is absolutely correct. The drag and drop he has mentioned appeared in my failure test just last week. Revise this !!

  12. Dec 2018 – drag and….
    December 11th, 2018

    mandatory check – Drag and drop each NAT64 description from the left onto the corresponding NAT64 type on the right. It was in last week as well.

    Question 11 doesn’t look correct to me

    + DHCPv6 Server:
    IPv6 address autoconfig
    IPv6 enable

    + Client Interface:
    IPv6 address
    IPv6 DHCP Relay destination

    It isn’t clear what it is asking but i would assume it is asking what configuration commands go under what devices.
    You are required to set up an IPv6 address on the server, and you also would put any DHCP relay commands there also, to point the client to the correct DHCP source (for the DNS details in this scenario).

    The client would then use Enable IPv6 command (often not required on Server side due to other commands enforcing IPv6 anyway). Then the client would use Auto-config to get it’s IPv6 address using the DHCP server that its relayed to)

    + DHCPv6 Client
    IPv6 enable
    IPv6 address autoconfig

    + DHCP server
    IPv6 address
    IPv6 DHCP Relay destination

    Maybe i am wrong, but it’s just how i see it and there is no explanation on here saying otherwise.

  16. MrTadge
    March 27th, 2019

    ignore my last comment.

    I didn’t realise it was meaning ;

    Configuration on the CLIENT FACING INTERFACE
    Configuration on the DHCP FACING INTERFACE

    it is the same device, i wrongly assumed they meant a client device and a router.

    Passed today, thanks to Digitaltut

    Labs/Sims: PBR, OSPF EIGRP Redistribution and OSPF Evaluation Sim.
    IP address changes from what is on digital tut. For redistribution do “sh int” to get the correct bandwidth and delay values.

    ACL D&D mGRe, IPSec,MSS D&D

    All questions were from here, 4 new questions in the exam.
    The OSPF EIGRP redistribution, i types “redistribute eigrp 100 metric-type 1 subnets”. When i do show run it was “redistribute eigrp 100 subnets metric0-type 1” , but I was able to ping though the running config was like that.

    I failed today in the CCNP route exam by reading only the question in 9tut. There are a lot of different questions are not in 9tut. Could anyone send me the latest dump exam or where to find it.

    @AlHafidhS – you need to study and learn concepts. Reading only the dumps is not enough to pass. I have studied hard and still failed by a small amount. Preparing for my 3rd attempt at the route exam.

    Stateless NAT64 and Stateful NAT64

    I got many questions today, keep the chart in memory.

    www . examtopics . com/exams/cisco/300-101/view/31/

    q 457 in the above url

    I passed with 869 today.
    I see IPv6 ospf virtual-link, ospf totally-stub, EIGRP
    and 5 drag &drops. frame-relay, DHCPv6, NAT64, AAA,and the other.
    a lot of questions that I haven’t ever seen in this web
    so if you understand all questions this site describes, it is not easy to pass this exam.
    but I want to help you, so I describe new questions below
    ・the difference between OSPFv2 & OSPFv3
    ・the difference between EIGRPv2 & EIGRPv3
    ・offset-list in RIPv2
    ・the problem when CAM timers is lower than ARP timers
    ・the difference between statefull NAT64 and Stateless NAT64(more specifically, and difficult)
    ・the problem when EIGRPv2 use on the VRF

    otherwise, I never see below
    ・policy-map
    ・redistribute
    ・URPF
    ・TCP&UDP(maybe one mf them was appeared)

    sim and lab is very easy, but options are very difficult
    best regards
