CCNP ENARSI Certification Cram Notes : Sample MCQs

9 Which of the following protocols is used to enable load balancing over multiple paths in MPLS networks?

a. IS-IS

b. OSPF

c. BGP

d. LDP

Answer: c. BGP

Explanation: GP is commonly used in MPLS networks to enable load balancing over multiple paths by leveraging its advanced features such as multipath and unequal-cost load balancing. While OSPF and IS-IS are used for building the MPLS forwarding tables, they do not have the same level of flexibility and scalability as BGP when it comes to load balancing. LDP is a label distribution protocol that is used to distribute labels for forwarding packets in MPLS networks, but it is not directly involved in load balancing.

10. Which of the following statements is true about Control Plane Policing (CoPP)?

a. It is used to secure the data plane of a network device.

b. It is used to secure the management plane of a network device.

c. It is used to secure the control plane of a network device.

d. It is used to secure the application plane of a network device.

Answer: c. It is used to secure the control plane of a network device.

VPN Technologies MCQs:

1. What is the purpose of a Virtual Private Network (VPN)?

A) To provide secure access to resources over a public network

B) To provide high-speed connectivity over a private network

C) To provide access to resources only within a local network

D) To provide access to resources only within a specific geographic region

Answer: A

Explanation: The purpose of a VPN is to provide secure access to resources over a public network such as the Internet.

2. Which VPN technology is best suited for remote access scenarios?

A) MPLS VPN

B) Site-to-Site VPN

C) DMVPN

D) AnyConnect VPN

Answer: D

Explanation: AnyConnect VPN is best suited for remote access scenarios as it is designed to provide secure access to resources for remote users.

3. Which VPN technology uses a hub-and-spoke topology?

A) MPLS VPN

B) Site-to-Site VPN

C) DMVPN

D) AnyConnect VPN

Answer: C

Explanation: DMVPN uses a hub-and-spoke topology where the hub acts as a central point for all the spokes to connect to.

4. Which VPN technology provides dynamic routing between sites?

A) MPLS VPN

B) Site-to-Site VPN

C) DMVPN

D) AnyConnect VPN

Answer: C

Explanation: DMVPN provides dynamic routing between sites, allowing for more efficient routing and easier management.

5. Which VPN technology uses Label Distribution Protocol (LDP)?

A) MPLS VPN

B) Site-to-Site VPN

C) DMVPN

D) AnyConnect VPN

Answer: A

Explanation: MPLS VPN uses LDP to assign labels to packets and create virtual paths through the network.
