  Correct Answer: C

• Question 156:

  Refer to the exhibit.TCP traffic should be reaching host 10.10.10.10/24 via R2. Which action resolves the issue?

  

  A. Allow TCP in the access list with no changes to the route map.

  B. Set IP next-hop to 10.10.12.2 under the route-map permit 10 to allow TCP traffic.

  C. Add a permit 20 statement in the route map to allow TCP traffic.

  D. TCP traffic will reach the destination via R2 without any changes.

  Correct Answer: A

  If we add a "permit 20" statement in the route-map then we will allow other traffic to pass through (in fact Policy-based routing allows other traffic to pass through by default). But the bandwidth of R1-R4 is higher than that of R1-R2 so TCP traffic might go through R4 instead of R2. Therefore we should allow TCP in the ACL so that TCP traffic is forwarded via R2.

• Question 157:

  Refer to the exhibit. A network administrator notices these console messages from host 10.11.110.12 originating from interface E1/0. The administrator considers this an unauthorized attempt to access SNMP on R1. Which action prevents the attempts to reach R1 E1/0?

  

  A. Configure IOS management plane protection using ACL 90 on interface E1/0.

  B. Configure IOS control plane protection using ACL 90 on interface E1/0.

  C. Add a permit statement including the host 10.11.110.12 into ACL 90.

  D. Create an inbound ACL on interface E1/0 to deny SNMP from host 10.11.110.12.

  Correct Answer: D

• Question 158:

  Refer to the exhibit.R4 is experiencing packet drop when trying to reach 172.16.2.7 behind R2. Which action resolves the issue?

  

  A. Insert a /24 floating static route on R2 toward R3 with metric 254.

  B. Disable auto summarization on R2.

  C. Insert a /16 floating static route on R2 toward R3 with metric 254.

  D. Enable auto summarization on all three routers R1, R2, and R3.

  Correct Answer: B

• Question 159:
