Question No: 271 – (Topic 3)

A new BGP session has been configured. Upon monitoring the session state, you notice that the session has just transitioned from connect state to active state. What does the active state indicate for this BGP session?

  1. Something is wrong with your configuration. You must check your configuration and try again.

  2. This is the expected behavior. You should wait longer for the BGP session to establish.

  3. The OPEN messages collided. One BGP peer must be configured with the passive option.

  4. No route exists to the neighbors peering address. Check the IGP for reachability.

Answer: B

Question No: 272 – (Topic 3)

You add a GRE tunnel to transport packets between two routers. After implementing this, you notice an increase in the number of dropped packets. While looking at packet captures, you notice that the do-not-fragment (DF) bit is set in the IP header of all the dropped packets.

What would cause this changed behavior?

  1. The GRE tunnel has a lower MTU than the physical interface.

  2. GRE tunnels do not support fragmentation.

  3. GRE tunnels do not support the DF bit.

  4. The GRE tunnel has a higher MTU than the physical interface.

Answer: A

Question No: 273 – (Topic 3)

Which two statements are true of OSPF stub areas? (Choose two.)

  1. Stub areas might contain ASBRs and can receive external Extern (Type 5) LSAs from other areas.

  2. Stub areas cannot be crossed in the creation of a virtual link.

  3. Stub areas cannot receive any Summary (Type 3) LSAs.

  4. Stub areas cannot contain an ASBR.

Answer: B,D

Question No: 274 – (Topic 3)

Two routers have established a peering using EBGP over a single T1 link. How often will the routing table be synchronized between the two routers?

  1. every 30 minutes

  2. when an update message is received

  3. every 30 seconds

  4. when a notification message is received

Answer: B

Question No: 275 – (Topic 3)

Which statement describes the operation of a stub area?

  1. A stub area receives only a default route.

  2. A stub area receives all routes from all other areas.

  3. A stub area receives no external routes from other areas.

  4. A stub area is automatically configured based on the presence of the E-bit in the hello messages sent from the ABR.

Answer: C

Question No: 276 – (Topic 3)

Which two statements describe STP and RSTP interoperability? (Choose two.)

  1. STP protocol discards any RSTP BPDUs it receives.

  2. STP protocol accepts RSTP BPDUs but will not respond.

  3. RSTP accepts STP BPDUs and responds with STP BPDUs.

  4. RSTP discards STP BPDUs.

Answer: A,C

Question No: 277 – (Topic 3)

Router A and Router B are on the same network segment and in the same OSPF area.

Router A receives an LSA header from Router B that is not currently in its own database. Which OSPF packet type does Router A send to Router B?

  1. Type 1

  2. Type 2

  3. Type 3

  4. Type 4

Answer: C

Question No: 278 – (Topic 3)

Which statement is true of BGP communities?

  1. Communities are used to identify BGP routes based on the originating route#39;s attributes, whether it is an internal route, an external route, or unknown.

  2. Communities are added by route reflectors. A route reflector appends its own IP address and the autonomous system number separated by a colon in the community field each time a route traverses it.

  3. Communities are used to determine preference within a network; lower community values are more preferable than higher values.

  4. Communities are used as a tool for sorting and categorizing routes based on user- defined criteria.

Answer: D

Question No: 279 – (Topic 3)

Router 2 is receiving a route to from Router 4 and Router 5. What will Router 2 do with the routes shown in the exhibit?

  1. Router 2 will mark both routes active if both next hops are reachable.

  2. Router 2 will prefer the route received from Router 4 because of a lower origin code value.

  3. Router 2 will prefer the route that arrived first because neither route is necessarily preferable over the other.

  4. Router 2 will prefer the route received from Router 5 because it has a lower MED value.

Answer: B

Question No: 280 – (Topic 3)

Which two packet types are handled solely by the RE within an EX4200? (Choose two.)

  1. OSPF hellos

  2. DHCP relay

  3. STP BPDUs

  4. IP multicast traffic
