NEW QUESTION # 245
During BGP route summarization configuration, the keyword can be used to suppress all specific routes so that only the summary route is advertised. The summary route carries the Atomic-aggregate attribute rather than the community attributes of specific routes.
Answer:
Explanation:
suppress-spec-map
Explanation:
Understanding BGP Route Summarization:
* In Border Gateway Protocol (BGP), route summarization is a technique used to aggregate multiple specific prefixes into a broader summary prefix. This reduces the size of routing tables and improves routing efficiency.
* Summarization helps to hide unnecessary details from other parts of the network while still maintaining connectivity.
NEW QUESTION # 246

NEW QUESTION # 247
Which of the following statements are false about VRRP timers?(Select all that apply)
Answer: A,B
Explanation:
A is false- The correct formula is: Skew_Time = (256 - Priority)/256 ร Advertisement_Interval.
B is false- By default, thepreemption delayis typically0s, not 1s, meaning a higher-priority backup router can preempt immediately unless configured otherwise.
C is true- Thedefault Advertisement intervalin VRRP is2 seconds.
D is true- The formula Master_Down_Interval = 3 ร Advertisement_Interval + Skew_Time is correct.
Reference from Huawei HCIP-Datacom-Core Technology Study Guide:
"The VRRP Skew_Time is calculated as (256 - Priority)/256 ร Adver_Interval. The Master_Down interval includes this Skew_Time to stagger failover." (Chapter: High Availability - Section: VRRP Timer Mechanism)
NEW QUESTION # 248
On an IS-IS network, the length and components of a NET are the same as those of an NSAP. Which of the following NET fields is used to uniquely identify a host or router in an area?
Answer: D
Explanation:
Comprehensive and Detailed In-Depth Explanation:
* NET (Network Entity Title) is a special form of NSAP (Network Service Access Point) used in IS- IS routing.
* NET consists of three fields:
* AFI (Authority and Format Identifier) + IDI (Initial Domain Identifier) + Area Address # Identifies the area.
* System ID # Uniquely identifies a router within an area (similar to an OSPF Router ID).
* SEL (NSEL - N-selector) # Always 0 in a NET, as IS-IS operates at Layer 3.
* Since System ID uniquely identifies a host/router within an area, the correct answer is A.
