NEW QUESTION # 237
A network administrator runs the display telemetry subscription command on a device to check telemetry subscription information. The command output is as follows. Which of the following statements is incorrect?
[~CE] display telemetry subscription
Sub name : Sub1
Sensor group:
Sensor-name Sample-interval(ms) State
Sensor1 1000 RESOLVED
Destination group:
Dest-name Dest-IP Dest-port State Vpn-name Protocol
Dest1 192.168.56.1 20030 RESOLVED - GRPC
Sub state : PASSIVE
Total subscription number is : 1
Answer: D
Explanation:
A . The device sends sampled data every second → Correct, since sample interval is 1000ms = 1 second.
B . The subscription mode is static subscription → Correct, as shown by Sub state: PASSIVE. Passive indicates a static subscription.
C . The IP address of the device is 192.168.56.1 → Incorrect - this IP address is the destination (telemetry collector), not the device's own IP.
D . The subscription name is Sub1 → Correct, as per Sub name : Sub1.
Correct answer: C. The IP address of the device is 192.168.56.1 - this is incorrect because it's actually the collector's IP, not the device's.

Answer: A
NEW QUESTION # 239
On the network shown in the figure, OSPF-based SR-MPLS TE is enabled on all routers. Which of the following adjacency labels are allocated by P3?
Answer: A,D
Explanation:
In OSPF-based SR-MPLS TE, Adjacency Segment Identifiers (Adj-SIDs) are locally assigned by each router for its directly connected interfaces. These labels are allocated from the Segment Routing Local Block (SRLB) configured on the router. By default, Huawei routers use an SRLB range starting at 9000, and Adj- SIDs are assigned sequentially (e.g., 9000, 9001, 9002, etc.) to each adjacency.
For P3, adjacency labels correspond to its outgoing interfaces. Assuming P3 has two adjacencies (e.g., to P2 and P4, as inferred from typical network topologies), it will allocate two unique Adj-SIDs from its SRLB.
Based on Huawei's implementation:
The first adjacency (e.g., to P2) is assigned the next available label in the SRLB (e.g., 9002).
The second adjacency (e.g., to P4) is assigned the subsequent label (e.g., 9003).
Analysis of Options:
Option B (9002): Likely assigned to P3's first adjacency (e.g., link to P2).
Option C (9003): Likely assigned to P3's second adjacency (e.g., link to P4).
Option A (9006) and D (9005): These labels are likely allocated by other routers (e.g., P4 or P5), as they fall outside the sequential range assigned by P3.
Key Points:
Adj-SIDs are local to the router and do not conflict with labels from other nodes.
The sequential allocation depends on the SRLB configuration. If the SRLB starts at 9000, labels 9000 and
9001 may be reserved for other purposes (e.g., node SIDs or reserved blocks), leaving 9002 and 9003 for adjacency labels.
Conclusion: P3 allocates 9002 and 9003 for its two adjacencies. Thus, B and C are correct.

NEW QUESTION # 240
In 6PE and 6VPE networking, no VPN instance needs to be created on PEs.
Answer: A
Explanation:
Understanding 6PE & 6VPE in MPLS Networks
6PE (IPv6 Provider Edge) and 6VPE (IPv6 VPN Provider Edge) are MPLS-based solutions that allow IPv6 traffic to be carried over an MPLS IPv4 core network without requiring the entire backbone to support IPv6.
# 6PE (IPv6 over MPLS - No VPN)
* Used for global IPv6 routing without VPN segmentation.
* No need for VRFs (VPN Routing and Forwarding instances) because IPv6 prefixes are handled natively.
# 6VPE (IPv6 VPN over MPLS - Supports VPNs)
* Extends MPLS L3VPN to support IPv6 routing inside VPN instances.
* Uses MP-BGP VPNv6 to distribute IPv6 prefixes inside MPLS VPNs.
Why is the Answer TRUE?
# No VRFs are required for 6PE:
* 6PE only needs BGP labeled IPv6 routes in the global routing table.
* IPv6 prefixes are carried using MPLS labels without VPN segmentation.
# VRFs are required for 6VPE, NOT for 6PE:
* 6VPE requires VPN instances (VRFs) for IPv6 L3VPNs, but 6PE does not.
# Real-World Application:
* 6PE is used in large ISP networks where IPv6 deployment is needed but without VPN separation.
* 6VPE is used for enterprise MPLS VPNs, allowing customers to have isolated IPv6 routing tables.

NEW QUESTION # 241
Fill in Blank
The ________ command can be run to completely isolate Layer 2 and Layer 3 of different interfaces in a VLAN. (Use lowercase letters to supplement the command, which cannot be abbreviated.)
Answer:
Explanation:
portisolateenable
Explanation:
The command port-isolate enable is used on Huawei switches to completely isolate traffic at both Layer 2 and Layer 3 between different interfaces within the same VLAN. This isolation prevents any communication between isolated ports-even if they belong to the same subnet or VLAN-making it a critical security feature in multi-tenant environments.
Usage Context:
Often used in shared service or hotel network scenarios.
Can be applied in access port configurations.
Does not require additional VLAN creation or private VLAN features.
Huawei Datacom Reference:
"To completely isolate Layer 2 and Layer 3 communication between interfaces in the same VLAN, run the port-isolate enable command under the interface view." (Source: HCIE-Datacom Study Guide V3.0 - Chapter: VLAN & Security Technologies, Section: Port Isolation)
