Huawei HCIP-Datacom-Advanced Routing & Switching Technology V1.0 Sample Questions (Q153-Q158):

NEW QUESTION # 153
On the IS-IS network shown in the figure, R1 imports a default route using the default-route-advertise always level-1 command. Which of the following statements are true?

  • A. Although the default-route-advertise always level-1 command is configured on R1, R1 cannot import the default route.
  • B. The default route exists in the routing table of R3.
  • C. The default route does not exist in the routing table of R1.
  • D. The default route exists in the routing table of R2.

Answer: C,D

Explanation:
Comprehensive and Detailed In-Depth Explanation:
Understanding the IS-IS Levels and Default Route Advertisement:
* R1 is a Level-1 router
* R2 is a Level-1-2 router (meaning it connects both Level-1 and Level-2 areas)
* R3 is a Level-2-only router
Step 1: What Does "default-route-advertise always level-1" Do?
* This command forces R1 to advertise a default route (0.0.0.0/0) to all its Level-1 IS-IS neighbors, regardless of whether R1 has a default route in its routing table.
* Since R1 is a Level-1 router, it does not participate in Level-2 routing, meaning it relies on R2 (a Level-1-2 router) for external connectivity.
Step 2: Checking the Routing Tables
* R1: Since it is only a Level-1 router and does not receive a default route from any higher-level router, it does not have a default route in its own routing table. # (D is correct)
* R2: Since R1 advertises the default route at Level-1, R2 (a Level-1-2 router) receives this default route in its Level-1 database. # (B is correct)
* R3: R3 is a Level-2-only router, and default routes are not automatically leaked between Level-1 and Level-2 unless explicitly configured.
* Since no explicit route leaking configuration is mentioned, R3 will not have the default route
# (C is incorrect).
* A is incorrect because the command successfully advertises a default route from R1 to Level-1 neighbors like R2.
Final answer: # B, D

NEW QUESTION # 154
After a fault occurs, you need to collect and back up various types of fault information in time as a reference for troubleshooting. In addition, when seeking emergency assistance from Huawei Technologies Co., Ltd.

  • A. False
  • B. True

Answer: B


NEW QUESTION # 155
BGP/MPLS IP VPN can only use LDP to construct public network free channels.

  • A. FALSE
  • B. TRUE

Answer: A


NEW QUESTION # 156
The figure shows information about VPN1 on a PE (Provider Edge) router in a BGP/MPLS IP VPN network.
When the VPNv4 route corresponding to VPN1 is advertised to the remote PE, which VPNs of the remote PE will accept the route?
VPN1 Configuration:
ip vpn-instance VPN1
ipv4-family
route-distinguisher 100:1
vpn-target 100:1 200:1 300:1 export-extcommunity
VPN Import Policies on the Remote PE:

  • A. VPN1: Import RT=100:1
  • B. VPN4: Import RT=500:1
  • C. VPN3: Import RT=100:1, 300:1
  • D. VPN2: Import RT=200:1, 400:1

Answer: A

Explanation:
Comprehensive and Detailed In-Depth Explanation:
1. Understanding Route Targets (RT) and Route Distribution in MPLS VPN
* MPLS Layer 3 VPNs (L3VPNs) use BGP to distribute VPN routes across multiple Provider Edge (PE) routers.
* Each VPN instance (VRF) is configured with Route Targets (RTs) to control which VPN routes are imported/exported.
* Route Distinguishers (RDs) are unique per VRF but do not affect route selection.
2. Analyzing VPN1 Configuration
* VPN1 is exporting routes with the following Route Targets (vpn-target values):
* 100:1
* 200:1
* 300:1
* Remote VPNs will import these routes only if their import RT list matches one of the exported RTs.
3. Matching Exported RTs with Import RTs in Remote VPNs
Remote VPN
Import RTs
Matches VPN1 Exported RTs (100:1, 200:1, 300:1)?
Accepts the Route?
VPN1
100:1
# Matches 100:1
# Yes
VPN2
200:1, 400:1
# Matches 200:1
# Yes
VPN3
100:1, 300:1
# Matches 100:1, 300:1
# Yes
VPN4
500:1
# No match
# No
# VPN1, VPN2, and VPN3 accept the route.# VPN4 does not accept the route because 500:1 is not in the export list of VPN1.
Final Conclusion:
# Correct answer: VPN1, VPN2, and VPN3 will accept the route.# VPN4 does not accept the route because there is no matching RT.
Thus, the correct answer is:# A. VPN1: Import RT=100:1# B. VPN2: Import RT=200:1, 400:1# C. VPN3:
Import RT=100:1, 300:1# D. VPN4: Import RT=500:1 (No match, does not accept the route).


NEW QUESTION # 157

  • A. Rl definitely generates a Network-LSA.
  • B. The Link-LSA generated by R2 does not exist in the LSDB of Rl.
  • C. R3 definitely generates an Intra-Area-Prefix-LSA.
  • D. R2 definitely generates a Link-LSA.

Answer: B,C,D
