Which of the following scenarios is not suitable for deploying interface PBR?
Options:
A.
A core switch needs to forward traffic between the intranet and extranet to an AC device that connects to the core switch in off-path mode.
B.
A core switch needs to forward the traffic between the intranet and extranet to a security detection device that connects to the core switch in off-path mode.
C.
A device needs to modify the next-hop IP address for locally originated traffic.
D.
On an enterprise network with multiple ISP outbound interfaces, each internal network segment accesses the Internet through a particular ISP outbound interface.
Policy-Based Routing (PBR) on interfaces is used to forward traffic based on specific policies rather than the routing table. However, PBR is not suitable for modifying the next-hop of locally originated traffic. Other scenarios listed are typical use cases for interface PBR .
Questions 5
Which of the following statements regarding IGMPv1 and IGMPv2 are true?
Options:
A.
1GMPv2 supports only general query.
B.
1GMPv2 defines the Leave message type.
C.
IGMPv1 does not define the IGMP Leave message type.
IGMPv1 supports general queries but does not define a Leave message. IGMPv2 introduces the Leave message type, which allows hosts to notify routers when they wish to leave a multicast group, improving efficiency. These distinctions align with the functionality of IGMP versions .

OSPF networks are classified into four types of networks by link layer protocol. Drag the following link layer protocols to the corresponding network types.(Token is reusable)
Network Types and Corresponding Link Layer Protocols
Broadcast: Ethernet
Point-to-Point (P2P): PPP, HDLC
Point-to-Multipoint (P2MP): PPP
Non-Broadcast Multi-Access (NBMA): Frame Relay
OSPF Network Types:OSPF classifies networks based on link layer protocols into the following types:
Broadcast: This type assumes that all routers on the network can communicate directly with one another using multicast or broadcast frames. Ethernet networks are typical examples.
Point-to-Point (P2P): This type is used for links that connect two routers directly. Common protocols include PPP (Point-to-Point Protocol) and HDLC.
Point-to-Multipoint (P2MP): This type simulates multiple point-to-point connections over a single physical network, often used in WAN scenarios where PPP is employed.
Non-Broadcast Multi-Access (NBMA): These networks connect multiple devices but lack native broadcast capability, such as Frame Relay.
[Reference: HCIP-Datacom-Core Technology Training Material (OSPF Network Types)., Explanation of Matches:, Broadcast - Ethernet: Ethernet supports broadcast and multicast communication, making it a suitable example of a broadcast OSPF network., P2P - PPP, HDLC: Both PPP and HDLC are designed for direct communication between two nodes, fitting the P2P category., P2MP - PPP: In WANs, PPP often operates in a point-to-multipoint configuration, simulating separate connections for each endpoint., NBMA - Frame Relay: Frame Relay is a classic NBMA technology where direct communication between devices requires manual configuration, as there is no inherent broadcast capability., Conclusion:This classification ensures that OSPF operates efficiently over different network types by adapting neighbor discovery and LSA propagation mechanisms to the underlying link layer technology., , ]
Questions 7
Which of the following PIM protocol packets have unicast destination addresses.
In the PIM protocol, Register Stop and Graft messages are sent with unicast destination addresses, typically to specific neighbors or RP (Rendezvous Point) routers. Other messages like Bootstrap and Assert use multicast addresses for broader dissemination across the network .
