Refer to the exhibit. If RTR01 is configured as shown, which three addresses will be received by other routers that are running EIGRP on the network? (Choose three.)
Answer: ACD
A, C and D auto summary uses "classful boundary" - 10.4.3.0 with mask 255.0.0.0 gives 10.0.0.0 - 172.16.4.0 with mask 255.255.0.0 gives 172.16.0.0 - 192.168.2.0 with mask 255.255.255.0 gives 192.168.2.0

Which configuration command can you apply to a HSRP router so that its local interface becomes active if all other routers in the group fail?
Answer: A
Fallback Mechanism: If all other routers in the HSRP group fail, the local router will transition to the active state automatically as long as preemption is enabled

Which two statements about eBGP neighbor relationships are true? (Choose two.)
Answer: AB
"Just like OSPF or EIGRP, BGP establishes a neighbor adjacency with other BGP routers before they exchange any routing information. Unlike other routing protocols however, BGP does not use broadcast or multicast to “discover” other BGP neighbors. Neighbors have to be configured manually and BGP uses TCP port 179 for the connection."

Refer to the exhibit. How will the router handle a packet destined for 192.0.2.156?
Answer: C
Explanation: Router has pointed default router to 192.168.4.1 and this subnet is connected via serial 2 interface. Router does not have router for the 192.0.2.156. so it will use the default gateway 192.168.4.1. A default route identifies the gateway IP address to which the router sends all IP packets for which it does not have a learned or static route.

Which statements describe the routing protocol OSPF? (Choose three.)
Answer: ACE
D probaly would is right too. If you gonna use OSPF you have more Routing overhead in your network. If its already implemented you can reduce the overhead by building different areas. All in all it increases the overhead. Answers by Question 184 proofs it

Refer to the exhibit. After you apply the given configurations to R1 and R2 you notice that OSPFv3 fails to start.
Answer: A
I think the answer is correct, because "ospf fails to START" and the only must-have requirements for ist to start are matching area IDs and hello/dead timers. Correct me, if I'm wrong

Which command is used to display the collection of OSPF link states?
Answer: D
The "show ip ospf database" command displays the link states. Here is an example: Here is the lsa database on R2. R2#show ip ospf database - OSPF Router with ID (2.2.2.2) (Process ID 1) Router Link States (Area 0) Link ID ADV Router Age Seq# Checksum Link count2.2.2.2 2.2.2.2 793 0x80000003 0x004F85 210.4.4.4 10.4.4.4 776 0x80000004 0x005643 1111.111.111.111 111.111.111.111 755 0x80000005 0x0059CA 2133.133.133.133 133.133.133.133 775 0x80000005 0x00B5B1 2 Net Link States (Area 0) Link ID ADV Router Age Seq# Checksum10.1.1.1 111.111.111.111 794 0x80000001 0x001E8B10.2.2.3 133.133.133.133 812 0x80000001 0x004BA910.4.4.1 111.111.111.111 755 0x80000001 0x007F1610.4.4.3 133.133.133.133 775 0x80000001 0x00C31F
Refer to the exhibit. A network associate has configured OSPF with the command: City(config-router)# network 192.168.12.64 0.0.0.63 area 0 After completing the configuration, the associate discovers that not all the interfaces are participating in OSPF. Which three of the interfaces shown in the exhibit will participate in OSPF according to this configuration statement? (Choose three.)
Answer: BCD
The "network 192.168.12.64 0.0.0.63 equals to network 192.168.12.64/26. This network has: ✑ Increment: 64 (/26= 1111 1111.1111 1111.1111 1111.1100 0000) + Network address: 192.168.12.64 ✑ Broadcast address: 192.168.12.127 Therefore all interface in the range of this network will join OSPF.

Refer to the exhibit. C-router is to be used as a "router-on-a-stick" to route between the VLANs. All the interfaces have been properly configured and IP routing is operational. The hosts in the VLANs have been configured with the appropriate default gateway. What is true about this configuration?
Answer: D
Since all the same router (C-router) is the default gateway for all three VLANs, all traffic destined to a different VLA will be sent to the C-router. The C-router will have knowledge of all three networks since they will appear as directly connected in the routing table. Since the C-router already knows how to get to all three networks, no routing protocols need to be configured.

A frame that enters a switch fails the Frame Check Sequence. Which two interface counters are incremented? (Choose two.)
Answer: AD
input errors: total of many counters, including all below frame: Frames on illegal format. Can be caused by collisions giants: Frames that exceeded the maximum size (1518 bytes) CRC: Received frames that did not pass the FCS math runts: Frames that did not meet the minimum size (64 bytes). Can be caused by collisions Therefore CRC and INPUT ERRORS will be increased.
