NEW QUESTION # 266
Vectoring is classified only as system-level vectoring (SLV) and node-level vectoring (NLV) based on system architectures.
- A. TRUE
- B. FALSE
Answer: B
Explanation:
Vectoring Classification:
Vectoring is primarily classified into two types based on the scope of crosstalk cancellation:
System-Level Vectoring (SLV): Applies to all lines within a single DSLAM or cabinet.
Node-Level Vectoring (NLV): Applies to lines across multiple DSLAMs or nodes.
However, these are not the only classifications. Other implementations, such as hybrid approaches, may also exist depending on the network design.
Why FALSE?
The statement incorrectly claims that vectoring is classified only as SLV and NLV, ignoring other possible implementations or variations.
Thus, the correct answer is B.

NEW QUESTION # 271
When configuring a bridging ONU, how do you set the VLAN of the ETH1 port if the ETH1 port is used for a PC to access the Internet?
- A. Configure VLAN 1 on ETH1.
- B. Configure a native VLAN.
- C. Use the default configuration of the ETH1 port.
- D. Configure VLAN 4094 on ETH1.
Answer: B
Explanation:
* Bridging ONU Configuration :
* A bridging ONU acts as a transparent bridge between the PC and the OLT, forwarding traffic without modifying it.
* VLAN Configuration for ETH1 :
* VLAN 1 : The default VLAN, often reserved for management purposes. Using it for Internet access is not recommended.
* Default Configuration : Leaving the port unconfigured may result in improper VLAN tagging or untagged traffic, leading to connectivity issues.
* VLAN 4094 : Typically reserved for special purposes (e.g., QinQ termination) and is not suitable for general Internet access.
* Native VLAN : Configuring a native VLAN ensures that untagged traffic from the PC is associated with the correct VLAN for Internet access.
* Why D?
* Configuring a native VLAN is the correct approach to ensure proper VLAN tagging and seamless Internet access for the PC connected to ETH1.
Thus, the correct answer is D .

NEW QUESTION # 281
The routing table of a router contains the following two entries:
Destination/Mask Protocol Pre Cost Nexthop Interface
9.0.0.0/8 OSPF 10 50 1.1.1.1 Serial0
9.1.0.0/16 RIP 100 5 2.2.2.2 Ethernet0
If the router needs to forward packets with the destination address of 9.1.4.5, which of the following statements is correct?
- A. The router selects the second route, because this route matches the destination address 9.1.4.5 more accurately.
- B. The router selects the second route, because the outbound interface is Ethernet0, which is faster than Serial0.
- C. The router selects the second route, because the metric of RIP is smaller.
- D. The router selects the first route, because the priority of OSPF is higher.
Answer: A
Explanation:
When a router forwards packets, it selects the route with the longest prefix match (most specific route) for the destination address.
* First Route : Matches 9.0.0.0/8, which covers all IP addresses starting with 9.
* Second Route : Matches 9.1.0.0/16, which is more specific and covers IP addresses starting with 9.1.
For the destination address 9.1.4.5 , the second route (9.1.0.0/16) is a better match because it is more specific than the first route (9.0.0.0/8).
* Option A : Incorrect. OSPF has a higher priority, but the longest prefix match takes precedence over priority.
* Option B : Correct. The second route matches the destination address more accurately.
* Option C : Incorrect. Metric is not considered when comparing routes with different prefix lengths.
* Option D : Incorrect. Interface speed is irrelevant in route selection.
