NEW QUESTION # 75
GRE is a VPN technology that can implement packet transmission over heterogeneous networks. Which of the following statements are true about GRE?

  • A. GRE tunnels can extend the working range of network protocols with hop limits.
  • B. GRE is a Layer 2 VPN encapsulation technology.
  • C. GRE enables encapsulated data packets to be transmitted over another network layer protocol, butcannot encapsulate multicast data.
  • D. GRE tunnels can work with IPsec to ensure the security of multicast services such as voice and video.

Answer: A,D

Explanation:
Comprehensive and Detailed Step-by-Step Explanation:
1. What is GRE (Generic Routing Encapsulation)?
GRE is a tunneling protocol that allows the encapsulation of various types of packets (e.g., IPv4, IPv6, multicast, etc.) to be transmitted over another protocol (e.g., IP).
GRE is used to create point-to-point connections over heterogeneous networks.
2. Analysis of Each Option:
Option A: GRE is a Layer 2 VPN encapsulation technology.
Incorrect.
GRE operates at Layer 3 (Network Layer) and encapsulates Layer 3 packets. It is not a Layer 2 VPN encapsulation technology like MPLS or Ethernet-over-IP.
Option B: GRE enables encapsulated data packets to be transmitted over another network layer protocol, but cannot encapsulate multicast data.
Incorrect.
GRE supports the encapsulation and transmission of multicast data packets. This is one of its key features, making it suitable for protocols like OSPF and multicast applications.
Option C: GRE tunnels can work with IPsec to ensure the security of multicast services such as voice and video.
Correct.
GRE by itself does not provide encryption or security. However, GRE can work with IPsec to secure the encapsulated traffic, including multicast data, for services like voice and video.
Option D: GRE tunnels can extend the working range of network protocols with hop limits.
Correct.
GRE encapsulates packets, effectively resetting their hop limits and allowing protocols with limited hop counts (e.g., RIP) to work over larger networks.
3. Summary:
The correct options areCandD.

NEW QUESTION # 76
Depending on the type of algorithms used, routing protocols are classified into distance-vector protocols and link-state protocols. Which of the following routing protocols are link-state protocols?

  • A. OSPF
  • B. IS-IS
  • C. BGP
  • D. RIP

Answer: A,B

Explanation:
Comprehensive and Detailed Step-by-Step Explanation:
* Distance-Vector Protocols:
* Distance-vector protocols determine the best path based on the distance to a destination and periodically share the entire routing table with neighbors.
* Example: RIP is a distance-vector protocol.
* Link-State Protocols:
* Link-state protocols share information about directly connected links, enabling routers to build a complete map of the network.
* OSPF (Open Shortest Path First) and IS-IS (Intermediate System to Intermediate System) are link-state protocols that use Dijkstra's algorithm to calculate the shortest path.
* Border Gateway Protocol (BGP):
* BGP is neither a distance-vector nor a link-state protocol. Instead, it is classified as a path-vector protocol that selects the best path based on attributes such as AS-path, next-hop, and local preference.

NEW QUESTION # 77
The IP prefix list configuration on a Huawei router is shown below. Which of the following routes can match this IP prefix list?
bash
Copy
[huawei] ip ip-prefix test index 10 permit 10.0.0.0 8 less-equal 32

  • A. 10.1.1.0/6
  • B. 10.1.1.0/24
  • C. 10.1.1.1/32
  • D. 10.0.0.0/16

Answer: B,C,D

Explanation:
Comprehensive and Detailed Step-by-Step Explanation:
1. Understanding the Prefix List Configuration:
The command ip ip-prefix test index 10 permit 10.0.0.0 8 less-equal 32 defines the following:
The prefix base is 10.0.0.0 with a mask length of 8 bits.
The less-equal 32 condition allows routes with mask lengths ranging from 8 to 32 bits to match.
2. Analysis of Each Route:
Option A: 10.1.1.1/32
Correct.
The prefix 10.1.1.1/32 falls within the 10.0.0.0/8 network range and has a mask length of 32 bits, which satisfies the less-equal 32 condition.
Option B: 10.1.1.0/6
Incorrect.
The prefix 10.1.1.0/6 has a mask length of 6 bits, which is shorter than the base prefix length of 8. It does not satisfy the condition.
Option C: 10.1.1.0/24
Correct.
The prefix 10.1.1.0/24 falls within the 10.0.0.0/8 network range and has a mask length of 24 bits, which satisfies the less-equal 32 condition.
Option D: 10.0.0.0/16
Correct.
The prefix 10.0.0.0/16 falls within the 10.0.0.0/8 network range and has a mask length of 16 bits, which satisfies the less-equal 32 condition.
3. Summary:
The prefixes that match the configuration are 10.1.1.1/32, 10.1.1.0/24, and 10.0.0.0/16.

NEW QUESTION # 78
Regarding the route-policy set-cost configuration below, which of the following statements is true?

  • A. The route 11.1.0.0/16 is permitted by node 10, and its tost Is set to 300.
  • B. The cost of all routes is set to 200.
  • C. All the routes that are not permitted by node 10 will be denied.
  • D. The route 11.1.0.0/16 will continue to match node 20 after permitted by node 10, and (he final cost is set to 200.

Answer: A
