An engineer must design a WAN solution so that ISP-1 is always preferred over ISP-2. The path via ISP-2 is considered as a backup and must be used only when the path to ISP-1 is down. Which solution must the engineer choose?

  1. R1:
    - Routes advertised to ISP-1: 0x AS-path prepend- Routes
    received from ISP-1: HIGH local-preference- Routes
    advertised to R2: no action
    - Routes received from R2: community NO-EXPORT R2:
    - Routes advertised to ISP-2:5x AS-path prepend
    - Routes received from ISP-2: LOW local-preference-
    Routes advertised to R1: community NO-ADVERTISE-
    Routes received from R1: no action
  2. R1:
    - Routes advertised to ISP-1: 0x AS-path prepend
    - Routes received from ISP-1: HIGH local-preference
    - Routes advertised to R2: community NO-EXPORT
    - Routes received from R2: no action
    R2:
    - Routes advertised to ISP-2: 5x AS-path prepend
    - Routes received from ISP-2: LOW local-preference
    - Routes advertised to R1: no action
    - Routes received from R1: no action
  3. R1:
    - Routes advertised to ISP-1: 0x AS-path prepend
    - Routes received from ISP-1: LOW local-preference-
    Routes advertised to R2: community NO-ADVERTISE-
    Routes received from R2: no action
    R2:
    - Routes advertised to ISP-2: 5x AS-path prepend
    - Routes received from ISP-2: HIGH local-preference-
    Routes advertised to R1: no action
    - Routes received from R1: community NO-ADVERTISE
  4. R1:
    - Routes advertised to ISP-1: 5x AS-path prepend- Routes
    received from ISP-1: LOW local-preference- Routes
    advertised to R2: community NO-ADVERTISE- Routes
    received from R2: no action
    R2:
    - Routes advertised to ISP-2: 0x AS-path prepend- Routes
    received from ISP-2: HIGH local-preference- Routes
    advertised to R1: community NO-EXPORT- Routes
    received from R1: no action

Answer(s): B





requirements:

- Routers will double in all areas within the next 24 months.
- Link flaps within areas 20 and 30 must not impact the backbone area.
- Traffic originating from A201 and A302 routers must connect to application servers in the backbone.

Which design must the architect select?

  1. C101 Level 1/2, A201 Level 1, and A101 Level 2
  2. C201 Level 1/2, A301 Level 1/2, and A102 Level 1/2
  3. C302 Level 2, A302 Level 1/2, and A101 Level 2
  4. C102 Level 2, A202 Level 2, and A102 Level 1

Answer(s): A



An engineer must design a routing solution for a company that is single-homed to an ISP. The company's goal is to run BGP between the CE and the PE devices. To support running BGP, the company obtained a public AS number and IP subnet from ARIN. Which solution must the engineer select?


  1. - The customer announces the default route to the ISP.·
    The ISP announces the default route to the customer.

  2. - The customer announces the public IP subnet to the ISP.
    - The ISP announces the BGP table to the customer.

  3. - The ISP announces the customer public IP subnet.

    - The ISP announces the partial BGP table to the customer.

  4. - The customer announces the public IP subnet to the ISP.
    - The ISP announces the default route to the customer.

Answer(s): D



Refer to the exhibit. An engineer is designing a multicampus Layer 3 infrastructure using EIGRP as the routing protocol. The design must provide quick replies to queries in the event of a downlink, prevent unnecessary queries, and ensure that traffic does not unnecessarily transit the access layer. Which two actions must the engineer take for the network design? (Choose two.)

  1. Configure core layer switches as stub routers.
  2. Configure access layer and core layer switches as stub routers.
  3. Configure distribution layer switches to summarize routes to the core layer.
  4. Configure access layer switches as stub routers.
  5. Configure access layer switches to summarize routes to the distribution layer.

Answer(s): C,D





Refer to the exhibit. An engineer is planning an IPv4 to IPv6 migration solution for a customer. The routers in the network can support IPv4 and IPv6, except for the DWDM routers. The DWDM routers provide a Layer 2 link in which the routers peer directly with each other across a DWDM circuit. The circuit also provides connectivity between the mail servers. Which IPv6 migration technique must the engineer deploy?

  1. ISATAP
  2. dual-stack
  3. 6to4
  4. 6rd

Answer(s): A
