Week 4 Quiz Advanced Routing Protocols

What is the primary purpose of Border Gateway Protocol (BGP)?

• A. To provide dynamic IP address allocation
  

• B. To manage routing between Autonomous Systems (AS)
  

• C. To establish secure network tunnels
  

• D. To prioritize network traffic

What type of protocol is BGP?

• A. Interior Gateway Protocol (IGP)
  
  

• B. Exterior Gateway Protocol (EGP)
  

• C. Link-State Protocol
  

• D. Distance-Vector Protocol

Which transport layer protocol does BGP use?

• A. UDP
  

• B. ICMP
  

• C. SCTP
  

• D. TCP

In MPLS, what is the primary role of a label?

• A. It determines the physical path for the packet.
  
  

• B. It provides encryption for data in transit.
  

• C. It simplifies and speeds up packet forwarding.
  

• D. It identifies the source of the packet.

What is a key advantage of MPLS over traditional IP routing?

• A. It requires fewer routers in the network.
  
  

• B. It uses a simpler addressing scheme.
  

• C. It provides traffic engineering and quality of service (QoS).
  

• D. It eliminates the need for routing protocols.

What does an Autonomous System Number (ASN) uniquely identify?

• A. A specific router in a network
  
  

• B. A group of networks under a single administrative control
  

• C. A particular IP address block
  

• D. A BGP neighbor relationship

Which of the following is a valid BGP message type?

• A. Hello
  

• B. Keepalive
  

• C. Advertisement
  

• D. Query

What is the primary function of the BGP route selection process?

• A. To choose the fastest route based on latency
  
  
  

• B. To select the most secure route
  

• C. To determine the best path based on attributes
  

• D. To enable redundancy in the network

What attribute does BGP use to prefer a route within the same AS?

• A. Local Preference
  
  

• B. MED (Metric)
  

• C. AS Path
  

• D. Next-Hop

Which of the following is NOT a characteristic of MPLS?

• A. It supports Layer 2 and Layer 3 traffic.
  

• B. It replaces IP addresses with labels for forwarding.
  

• C. It requires changes to end devices for deployment.
  

• D. It enhances performance through traffic prioritization.
