Exam 350-401 topic 1 question 56 discussion

The most situable for this question is D (configure unique virtual address) as is one of requirements for a group to work, as seeing in the image. The others are wrong for the following reason. (so Wrong based in the question) A) Not mandatory the timers must match to work on HSRP. on HSRP negotiation the active router will override the standby timers. https://www.cisco.com/c/en/us/products/collateral/switches/catalyst-9000/nb-06-cat-9k-stack-wp-cte-en.pdf B) On the image key string match so is not this reason HSRP cant be seen each other C) Wrong, priority is for selecing the active router, the best practice is should be different thus (WRONG) D) Different virtual Gateway configured on the same group number indeed will make HSRP routers negotiation fail for that group thus (CORRECT)

There must be a typo in the possible answers as none of them are correct! D says to configure unique IP - they are already unique, but for HSRP to function, the virtual IP needs to match

All members of the same HSRP group must share the same virtual address, so we need to configure a unique virtual IP address for our HSRP group (Group 10)

These are all bad answers. Thre does need to be a single Virtual IP Address but the way D. is worded it sounds like R1 and R2 just need their own unique Virtual IP address which isn't the case either. The answer should really say something to the effect of: D. configure a shared unique Virtual IP address for the shared HSRP group of R1 and R2. That's the correct answer.

The answer is D in this case. Please note there's different variations of the exhibit. In another version, there's a difference in the key-string (cisco123! and Cisco123!).

it´s D, but the answer must be "configure a MATCHING virtual IP addresses", since they are already uniqe. B is wrong because both have Cisco123! as a key string, so they are matched.

The answer to this question is not listed. The Virtual IPs must be identical on each standby Group. Unique should read identical.

The R2 virtual IP doesn't match the R1's one

Answer :D  As per the output result, R1 was configured as an Active Router due to the high priority number 255. Authentication will pass due to the same on both sides. Timer mismatch in both sites is not a problem in this case. Because the timer of the Active router is less than the Standby router’s. I mean the active Router will send a Hello packet every 5 seconds and it is met with the Standby router timer.The main mismatch is the virtual IP address. The virtual IP address must be the same in both Routers’ configuration.

D is correct, R1 VIP is 192.168.0.1 R2 VIP is 192.165.0.1 They have to match

Admin need to correct this as there is no correct answer. The Virtual IPs MUST MATCH. If you look at the exhibit, you will see that R1 and R2 have different VIPs.

D is correct

In the exhibit, the VIPs do not match; second octet are different (168 vs 165) Assuming that the two routers do have connectivity between them for the interfaces configured for hsrp, they both would have IPs in either 192.168.0.0/24 or 192.165.0.0/24 Latter not likely since 192.165.0.0 is not one of the reserved private IPs. But hsrp configuration won't let you configure a VIP that doesn't match the interface subnet. So it is really unlikely D is the situation on the actual exam even if the exam had it as MATCHING since on the exam, they would already be matching.

D the keys are the same in the exhibit

In some places this question has a reference photograph and I see that the Virual IP is the same on both sides

The configuration is already got matching keys, the Virtual IP is not matching

I also go with D, if they can ask this exact question on the exam, they should give it as correct or they must say choose 2
