Sample ECP-206 Questions

Practice with real exam-style questions, each with the verified correct answer and explanation.

Q1 MultipleChoice

Which conceptual table created by routing protocols is used when processing an IP packet?

Correct Answer: D
Explanation:

The conceptual table created by routing protocols that is used when processing an IP packet is the forwarding information base (FIB). The FIB is a table that contains the best routes to reach each destination network prefix, along with the outgoing interface and the next-hop address for each route. The FIB is derived from the routing information base (RIB), which is a table that contains all the routes learned from different routing protocols and sources.The FIB is used by the router to make fast forwarding decisions for each incoming packet, based on its destination address12.

Q2 MultipleChoice

An operator wants to ensure that they can differentiate their traffic types for the purpose of prioritization in their Ethernet LAN and IP/MPLS backbone.

Which three fields would be used? (Choose three.)

Correct Answer: A, C, E
Explanation:

To differentiate traffic types for the purpose of prioritization in their Ethernet LAN and IP/MPLS backbone, an operator can use the following three fields:

Traffic Class (TC): This is a 3-bit field in the MPLS label that can be used to indicate the priority or class of service (CoS) of the packet. The TC field can be mapped to the DSCP field in the IP header or the PCP field in the Ethernet header.The TC field can be used by MPLS routers to apply different per-hop behaviors (PHBs) such as queuing, scheduling, and dropping policies to different traffic classes12.

DSCP: This is a 6-bit field in the IP header that can be used to mark packets according to the differentiated services (DiffServ) model. The DSCP field can indicate the per-hop behavior (PHB) that the packet should receive at each router along its path. The DSCP field can be mapped to the TC field in the MPLS label or the PCP field in the Ethernet header.The DSCP field can be used by IP routers to provide QoS for different traffic types34.

PCP: This is a 3-bit field in the Ethernet header that can be used to mark packets according to the IEEE 802.1Q standard. The PCP field can indicate the priority or class of service (CoS) of the packet on an Ethernet LAN. The PCP field can be mapped to the TC field in the MPLS label or the DSCP field in the IP header.The PCP field can be used by Ethernet switches to provide QoS for different traffic types56.

Q3 MultipleChoice

How many different priorities are available to use in a VLAN header?

Correct Answer: A
Explanation:

There are 8 different priorities available to use in a VLAN header. A VLAN header is a 4-byte field that is inserted into an Ethernet frame to indicate the VLAN membership and priority of the frame. The VLAN header consists of two subfields: the tag protocol identifier (TPID) and the tag control information (TCI). The TCI subfield contains three subfields: the priority code point (PCP), the drop eligible indicator (DEI), and the VLAN identifier (VID). The PCP subfield is a 3-bit field that specifies the priority level of the frame, ranging from 0 (lowest) to 7 (highest).The PCP values can be used to implement quality of service (QoS) mechanisms on bridges and switches12.

Q4 MultipleChoice

Which device will fragment IPv6 packets?

Correct Answer: A
Explanation:

The device that will fragment IPv6 packets is the source host. Fragmentation is a process of dividing a large packet into smaller pieces that can fit the maximum transmission unit (MTU) of the network link. In IPv4, fragmentation can be performed by either the source host or any intermediate router along the path. However, in IPv6, fragmentation is only allowed at the source host, and routers are not allowed to fragment packets. This reduces the processing overhead and complexity at routers and avoids potential fragmentation attacks.If a router receives an IPv6 packet that is too large for the next-hop link, it will drop the packet and send an ICMPv6 Packet Too Big message back to the source host56.

Q5 MultipleChoice

Which router function advertises external routes in OSPF?

Correct Answer: B
Explanation:

The router function that advertises external routes in OSPF is ASBR, which stands for Autonomous System Boundary Router. An ASBR is a router that connects an OSPF domain to another routing domain, such as another OSPF domain or a different routing protocol domain. An ASBR can redistribute routes from other routing domains into OSPF as external routes, which are carried in type 5 or type 7 LSAs. External routes have two types: E1 and E2.E1 routes include the cost from the ASBR to the destination, while E2 routes only include the cost advertised by the ASBR34.
