NEW QUESTION # 54
In SSP packages, Jinja2 templates are used to implement mapping. In the Jinja2 syntax, {% ... %} contains control structures, for example, a 'for' loop.

  • A. FALSE
  • B. TRUE

Answer: B

Explanation:
Understanding Jinja2 Templates in Huawei SSP Packages
#What is Jinja2?
Jinja2 is atemplating engineused inHuawei SSP (Smart Script Package) automation.
It allowsdynamic configuration generationbased on variables and logic.
#Jinja2 Syntax Basics:
#{% ... %}# Used forcontrol structureslike loops and conditions.
#{{ ... }}# Used forvariable placeholders.
Example of a Jinja2 Template Using {% ... %} for a Loop:
{% for interface in interfaces %}
interface {{ interface.name }}
description {{ interface.description }}
{% endfor %}
#This template dynamically generates interface configurationsbased on a list of interfaces.
Why is the Answer TRUE?
#{% ... %} is used for control structures in Jinja2 templates(e.g., loops, if-else statements).
#Jinja2 templates are widely used in SSP for Huawei network automation.
Real-World Application:
Automated Network Configuration:Uses Jinja2 inHuawei SSP automation scripts.
Data Center & SDN Automation:Dynamically generatesVXLAN, BGP, and OSPF configurations.

NEW QUESTION # 55
Regarding BGP MED, which of the following descriptions is correct?

  • A. By default, BGP routing rules can MED comparison of routes from different autonomous systems
  • B. In the BGP routing rules, MED has a lower priority than AS Path, Praferred-value, Local-Preference, etc Origin
  • C. By default, if there is no MED value in the route attribute, it is processed by 0 If the bestroute med-none-as-maximum command is configured, MED is processed as the maximum 4294967295
  • D. The default value for the BGP routing MED is 0

Answer: B,C,D


NEW QUESTION # 56
As shown in the figure, a sham link is established between PE1 and PE2 through the loopback interfaces. CE2 can learn the 192.168.1.0/24 route (directed route on CE1) through the sham link and backdoor link. If other parameters use their default settings, the cost of the 192.168.1.0/24 route on CE2 should be ______. (Enter an Arabic numeral without symbols.)

Answer:

Explanation:
20This is a classicMPLS L3VPN with OSPF + Sham Linkscenario.Key Components:CE1 to PE1 (GE0/0/0):
OSPF cost = 10CE2 to PE2 (GE0/0/0): OSPF cost = 10PE1 to PE2 via Sham Link (over loopback interfaces) What happens:CE1 advertises192.168.1.0/24to PE1.PE1 redistributes it into theVPNv4 BGProuting table.PE2 learns this route and redistributes it back into OSPF for CE2.Route Options Seen by CE2:Backdoor link (intra- area):CE1 # CE2 directly, via GE0/0/1 on each CE # OSPF cost = 10 + 10 =20Sham Link (inter-area route):
By default, if nosham linkis used, the BGP-learned route is treated as aninter-arearoute by CE2, with a default OSPF cost of1(which would make CE2 prefer this over the real CE-CE backdoor link).Purpose of Sham Link:
Sham linkis configured toequalizeoroverridethe cost of the BGP route so that CE2prefers the backdoor linkor sees both paths equally.In this case, Huawei defaults will cause CE2 to compute the total cost as:PE1-CE1 =
10Sham link route via PE1-PE2-CE2 = also10 (CE1 to PE1) + 10 (PE2 to CE2)=20Final OSPF Cost Calculation at CE2:Route learned via sham link path: 10 (CE1 to PE1) + 10 (PE2 to CE2) =20Correct answer:
20In Huawei MPLS L3VPN OSPF deployment:Asham linkensures that the cost via the MPLS VPN path iscomparable to the real CE-to-CE OSPF backdoor path, preventing suboptimal routing.Without sham link:
BGP redistributed routes appear asinter-area Type 3 LSAswith low cost (usually 1).With sham link: Route appears asintra-areaand OSPF calculates true cost based on interface metrics.


NEW QUESTION # 57
The following about the Router-LSA of OSPFv3 is correct?( Single choice questions).

  • A. The router-LSA data area contains the Interface ID of the neighbor on this side
  • B. Similar to OSPFv2, the Option field exists in the header of LSA, not in the data area of Router-LSA
  • C. When LS type= Ox0001 in the head of LSA, the data area representing LSA is Router-LSA
  • D. The router-LSA data area contains the Link-Local address

Answer: A


NEW QUESTION # 58
On a CloudCampus virtualized campus network, which of the following modes can be used by a fabric to connect to external networks?

  • A. Layer 3 exclusive egress
  • B. Layer 2 exclusive egress
  • C. Layer 2 shared egress
  • D. Layer 3 shared egress

Answer: A,B,C,D

Explanation:
Comprehensive and Detailed Explanation:
# All four egress modes are supported in Huawei CloudCampus Virtualized Fabric to provide flexibility in connecting external networks.
# Modes Explained:# Layer 3 Shared Egress # Multiple VNs share a single Layer 3 gateway for external communication.# Layer 2 Shared Egress # Multiple VNs share the same Layer 2 link to the external network.# Layer 3 Exclusive Egress # Each VN has its own separate Layer 3 gateway to external networks.
# Layer 2 Exclusive Egress # Each VN has its own dedicated Layer 2 link for external connectivity.
