Question 1 Domain 3Routing Protocols (OSPF, BGP, RIP)

Which statement accurately defines an Autonomous System (AS)?

Correct Answer: A
Explanation

The statement that accurately defines an Autonomous System (AS) is that an AS is a set of routers under a single administration, using an interior gateway protocol and common metrics to route packets within the AS. An AS is a logical grouping of networks that share a common routing policy and operate under a single administrative authority. An AS can be a single network or a collection of networks that are interconnected by routers. An AS uses an interior gateway protocol (IGP), such as OSPF or IS-IS, to exchange routing information within the AS. An IGP uses common metrics, such as hop count or bandwidth, to determine the best path to each destination within the AS. An AS also has a unique number assigned by IANA, called an AS number (ASN), which identifies the AS in interdomain routing .

Question 2 Domain 3Routing Protocols (OSPF, BGP, RIP)

Which route type is restricted in an OSPF stub area?

Correct Answer: D
Explanation

The route type that is restricted in an OSPF stub area is type 5. Type 5 LSAs are external LSAs that are generated by ASBRs to advertise routes from other routing domains or protocols into OSPF. Type 5 LSAs are flooded throughout the OSPF domain by default, except in stub areas. Stub areas are special OSPF areas that block type 5 LSAs from entering the area in order to reduce the size of the LSDB and the routing table.Stub areas only receive information about intra-area routes (type 1 and 2 LSAs), inter-area routes (type 3 LSAs), and a default route (type 3 LSA with destination 0.0.0.0/0) from the ABRs910.

Question 3 Domain 3Routing Protocols (OSPF, BGP, RIP)

What is the function of LSR from an LDP perspective?

Correct Answer: D
Explanation

The function of LSR from an LDP perspective is to distribute labels of FEC to its LDP peers. LSR stands for Label Switching Router, which is a router that forwards packets based on labels rather than IP addresses in an MPLS network. LDP stands for Label Distribution Protocol, which is a protocol that distributes labels for MPLS forwarding along the shortest path calculated by an IGP. FEC stands for Forwarding Equivalence Class, which is a group of packets that are forwarded in the same manner by an LSR.An LSR uses LDP to advertise the label mappings for each FEC to its LDP peers, which are other LSRs that have established an LDP session with it12.

Question 4 Domain 3Routing Protocols (OSPF, BGP, RIP)

How do peers recognize each other's ability to use MP-BGP extensions?

Correct Answer: A
Explanation

Peers recognize each other's ability to use MP-BGP extensions by advertising the ability using the capabilities field during the session establishment. MP-BGP is an extension to BGP that allows BGP to carry routing information for multiple network layer protocols, such as IPv6, VPNv4, multicast, etc. To support MP-BGP, peers need to exchange their capabilities during the session establishment phase, which consists of three steps: open, keepalive, and update. In the open message, peers can include an optional parameter called capabilities, which indicates what kind of address families and subsequent address families they can support.If both peers agree on a common set of capabilities, they can proceed to exchange routing information for those address families using update messages56.

Question 5 Domain 4Network Address Translation (NAT)

Review the exhibit.

A service provider wants to connect the sites for two customers (indicated in red and green in the exhibit). The two customers are using the same IP ranges 192.168.0.0/16.

Referring to the exhibit, what should the service provider do to accomplish this task?

Correct Answer: A
Explanation

Referring to the exhibit, the service provider should implement L3VPN using the MP-BGP protocol to connect the sites for two customers (indicated in red and green in the exhibit). L3VPN is a type of VPN that uses MPLS to provide IP connectivity between customer sites across a service provider network. L3VPN allows customers to use overlapping or identical IP addresses without causing conflicts or requiring NAT. L3VPN uses MP-BGP to exchange VPN routes between PE routers, which are routers that connect customer networks to the service provider network. MP-BGP is an extension of BGP that can carry multiple address families, such as VPNv4 or VPNv6, along with additional attributes, such as route distinguisher (RD) and route target (RT).RD is used to make customer routes unique within the service provider network, while RT is used to control which routes are imported or exported between different VPNs3.

Question 6 Domain 3Routing Protocols (OSPF, BGP, RIP)

What is the correct ordering (outer to inner) of packet headers in an IP/MPLS packet?

Correct Answer: A
Explanation

The correct ordering (outer to inner) of packet headers in an IP/MPLS packet is Ethernet, MPLS, IP. An IP/MPLS packet is a packet that is encapsulated with an MPLS label stack between the Ethernet header and the IP header. The Ethernet header contains the source and destination MAC addresses and the EtherType field that indicates the type of the payload. The MPLS label stack contains one or more labels that are used for forwarding decisions by the MPLS routers. Each label consists of four fields: label value, experimental bits, bottom of stack, and time to live. The IP header contains the source and destination IP addresses and other information for routing and fragmentation.The order of the headers is important because it determines how the packet is processed by different devices in the network12.

Question 7 Domain 4Network Address Translation (NAT)

What is the purpose of the RT attribute?

Correct Answer: A
Explanation

The purpose of the RT attribute is to identify the destination VPN on the egress PE. RT stands for route target, which is a BGP extended community attribute that is used in MPLS VPNs. RT is attached to VPN routes by the ingress PE router and is used to control the import and export of routes between different VPNs.The egress PE router uses the RT value to determine which VPN routes belong to which VPN customers and installs them in the appropriate VRF table56.
