300-410 Practice Test practice questions, page 3 of 25, with answer review and explanations.

Question 11

Refer to the exhibit. R2 is a route reflector, and R1 and R3 are route reflector clients. The route reflector learns the route to 172.16.25.0/24 from R1, but it does not advertise to R3. What is the reason the route is not advertised?

  1. R2 does not have a route to the next hop, so R2 does not advertise the prefix to other clients.
  2. Route reflector setup requires full IBGP mesh between the routers.
  3. In route reflector setup, only classful prefixes are advertised to other clients.
  4. In route reflector setups, prefixes are not advertised from one client to another.

Question 12

Refer to the exhibit. An engineer is trying to redistribute OSPF to BGP, but not all of the routes are redistributed. What is the reason for this issue?

  1. By default, only internal routes and external type 1 routes are redistributed into BGP
  2. Only classful networks are redistributed from OSPF to BGP
  3. BGP convergence is slow, so the route will eventually be present in the BGP table
  4. By default, only internal OSPF routes are redistributed into BGP

Question 13

Refer to the exhibit. In which circumstance does the BGP neighbor remain in the idle condition?

  1. if prefixes are not received from the BGP peer
  2. if prefixes reach the maximum limit
  3. if a prefix list is applied on the inbound direction
  4. if prefixes exceed the maximum limit

Question 14

Which attribute eliminates LFAs that belong to protected paths in situations where links in a network are connected through a common fiber?

  1. shared risk link group-disjoint
  2. linecard-disjoint
  3. lowest-repair-path-metric
  4. interface-disjoint

Question 15

Refer to the exhibit. An engineer is troubleshooting BGP on a device but discovers that the clock on the device does not correspond to the time stamp of the log entries. Which action ensures consistency between the two times?

  1. Configure the service timestamps log uptime command in global configuration mode.
  2. Configure the logging clock synchronize command in global configuration mode.
  3. Configure the service timestamps log datetime localtime command in global configuration mode.
  4. Make sure that the clock on the device is synchronized with an NTP server.
