Question #11
An engineer sees that traffic is not flowing between two line cards on a Cisco ASR 9000 Series device. To troubleshoot this issue, what should the engineer do first?
  1. A
    Verify whether there are errors on the EOBCs.
  2. B
    Verify whether there are PFM alarms on the line cards and RSPs.
  3. C
    Verify whether LPTS configuration is prohibiting traffic between the two line cards.
  4. D
    Verify whether there are alarms in the system diagnostics.

Correct Answer:
B

Question #12
Which standard provides insurance that the new hardware rollout plan meets certain environment design guidelines before deployment?
  1. A
    ITIL ®
  2. B
    eTOM
  3. C
    NEBS
  4. D
    COBIT
  5. E
    NAS

Correct Answer:
C

Question #13
Which statement about LDP Session Protection and LDP IGP sync is true?
  1. A
    Both LDP features must be used together to increase fast convergence on a MPLS LDP-enabled network.
  2. B
    Both LDP features cannot be used at the same time in a MPLS LDP enabled network.
  3. C
    LDP Session Protection re-exchanges label information when a down-up event occurs LDP-IGP sync keeps the adjacency and label information in a down-up event.
  4. D
    LDP-IGP sync re-exchanges label information when a down-up event occurs; LDP Session Protection keeps the adjacency and label information in a down-up event.

Correct Answer:
A

Question #14
A service provider is running a single-area OSPFv2 interface in the MPLS network. The OSPF reconvergence time is becoming excessively slow as the service provider MPLS grows. Which two actions can improve network performance without implementing a multiarea design? (Choose two.)
  1. A
    implement Partial Route Computation
  2. B
    enable LSA group pacing
  3. C
    configure incremental SPF
  4. D
    reduce type 5 LSAs
  5. E
    limit the number of TLVs

Correct Answer:
BC

Question #15
Which OSPFv3 LSA is never flooded beyond the link?
  1. A
    interarea router LSA
  2. B
    link LSA
  3. C
    intra-area prefix LSA
  4. D
    router LSA
  5. E
    network LSA

Correct Answer:
B
A router originates a separate Link LSA for each link itis attached to. These LSAs have link-local flooding scope and are never flooded beyond a link that they are associated with.

Question #16
A service provider engineering team must design a solution that supports end-to-end LSPs for multiple IGP domains within different AS numbers.
According to RFC 3107, which solution achieves this goal?
  1. A
    LDP and BGP
  2. B
    BGP and send-label
  3. C
    RSVP and IS-IS or OSPF
  4. D
    RSVP and BGP
  5. E
    mLDP

Correct Answer:
B

Question #18

Refer to the exhibit. Which OSPFv3 redistribute configuration provides the equivalent results when redistributing from EIGRP IPv6 prefixes on to OSPFv3 as it happens when redistributing from EIGRP IPv4 prefixes onto OSPFv2?
  1. A
    ipv6 router ospf 10redistriute eigrp 10
  2. B
    ipv6 router ospf 10redistriute eigr 10 connected
  3. C
    ipv6router ospf 10redistriute eigrp 10 include-connected
  4. D
    ipv6 router ospf 10redistriute eigrp 10redistriute connected

Correct Answer:
C

Question #19
A service provider is using point-to-multipoint TE to forward MPLS traffic from one source to multiple destinations. What is a restriction of using the method?
  1. A
    Only node protection is supported on point-to-multipoint TE LSPs.
  2. B
    Point-to-multipoint TE does not support policy-based routing.
  3. C
    Multicast traffic must be implemented using PIM sparse mode.
  4. D
    Destinations must be manually added and remoted on the TE tail-end router.

Correct Answer:
B

Question #20
DRAG DROP -
A U.S. service provider has POPs across the U.S. and Canada. Some links are satellite links, other are fiber optics links. A design engineer has flagged all these links in the network by using the MPLS traffic Engineering attribute, as per the following: i. All satellite links are marked as affinity value 0x2. ii. All links outside of the U.S. are marked as affinity value 0x8.
A service provider operations engineer has a requirement to create an MPLS TE tunnel for voice traffic, using only U.S. links, by applying the tunnel mpls traffic- eng affinity <affinity-value> <affinity-mask> command.
Drag and drop the hexadecimal value on the left onto the affinity-value on the right to be used on this MPLS TE tunnel. Also drag and drop the hexadecimal value on the left onto the affinity-mask on the right to be used on this MPLS TE tunnel.
