Compared with RSTP, which of the following port roles are added to MSTP?

A. Edge port
B. Master port
C. Regional edge port
D. Backup port

Answer: B,C

Explanation:
Additional Port Roles in MSTP
* Master Port: Indicates the port on the shortest path to the root bridge in a region.
* Regional Edge Port: Identifies a port at the boundary of the MST region.
* Backup and edge ports exist in RSTP and are not newly introduced by MSTP.
HCIP-Datacom-Core Reference
* MSTP port roles are elaborated in the MSTP configuration sections.

NEW QUESTION # 116
PBR is a mechanism for selecting routes based on user-defined policies. There are two types of PBR:
interface-based PBR and local PBR. Which of the following statements is false about these two types of PBR?

A. Local PBR is configured in the protocol view.
B. Interface-based PBR is configured on an interface and takes effect only for incoming packets on the interface.
C. Interface-based PBR takes effect only for forwarded packets.
D. Local PBR takes effect only for locally originated packets.

Answer: A

Explanation:
Comprehensive and Detailed Step-by-Step Explanation:
1. Overview of PBR (Policy-Based Routing):
Policy-Based Routing (PBR) allows you to override traditional routing decisions by defining user-specific policies.
* Interface-Based PBR: Applied to packets arriving at a specific interface and affects traffic being forwarded through the device.
* Local PBR: Applied to traffic generated by the local router itself (e.g., locally originated packets such as management traffic).
2. Analysis of Each Statement:
Option A: Interface-based PBR takes effect only for forwarded packets.
* Correct (True Statement).
* Interface-based PBR applies only to packets arriving at a specific interface and being forwarded through the router. It does not affect locally originated traffic.
Option B: Local PBR takes effect only for locally originated packets.
* Correct (True Statement).
* Local PBR specifically applies to traffic generated by the router itself, such as pings, SNMP requests, or routing protocol updates.
Option C: Interface-based PBR is configured on an interface and takes effect only for incoming packets on the interface.
* Correct (True Statement).
* Interface-based PBR is applied directly on the interface using commands like policy-based-route. It only affects traffic entering the specified interface.
Option D: Local PBR is configured in the protocol view.
* Incorrect (False Statement).
* Local PBR is not configured in the protocol view. It is typically configured using the command local- policy in the system view to handle traffic generated by the router.
3. Summary:
D: (Local PBR is NOT configured in the protocol view).

NEW QUESTION # 117
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. RIP
C. BGP
D. IS-IS

Answer: A,D

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 # 118
On a WLAN, engineers can use the VLAN pool mechanism to assign access users to different VLANs, which helps reduce the number of broadcast domains and improve network performance. VLAN pools support two VLAN assignment algorithms: even and hash. Drag the advantages and disadvantages to the two algorithms.
(Token is reusable)

Answer:

Explanation:
Explanation of VLAN Pool Assignment Algorithms:
In WLANs, VLAN pools help reduce broadcast domains and improve network performance by distributing users across multiple VLANs. Two algorithms are used for VLAN assignment:
Even Assignment Algorithm:
* The number of users in each VLAN is even.
* This algorithm assigns users evenly across VLANs, ensuring a balanced distribution of users in each VLAN.
* When STAs go offline and online again, their VLANs and IP addresses may easily change.
* Since the assignment is based on maintaining even distribution, a device (STA) may not be assigned the same VLAN when it reconnects, leading to potential IP address changes.
Hash Assignment Algorithm:
* The number of users in each VLAN is uneven.
* The hash algorithm assigns users to VLANs based on a hash value (e.g., derived from the MAC address). This may result in an uneven distribution of users across VLANs.
* VLANs and IP addresses remain unchanged for STAs that go offline and online again.
* The hash algorithm ensures that a device reconnects to the same VLAN, preserving its IP address.
