Exam NSE7_SDW-7.2 topic 1 question 34 discussion

B & C are correct, guide p.227. 0x1 means that only SLA target #1 passed. 0x2 means SLA target #2 passed/ 0x3 means both SLA targets passed

A. wrong T_INET_0 0x3 that means it passed 2 sla targets. If it missed then it missed 1 SLA target which is the 3bit in the SLA_MAP binary 3rd bit 4(0 off) 2nd bit 2(1bit on) first 1(1bit on) B. wrong T_INET_1 0x1 that means it passed 1 sla target. if it missed then it missed 2 2nd and 3rd bit in the sla_MAP therefore what is left is C,D correct

There is no way to prove a and b. However, we can make the assumption on D and C because there is more conclusive evidence

B & C correct

This configuration is... ｰｰｰｰｰｰｰｰｰｰｰｰｰｰｰｰｰｰｰｰｰｰｰｰｰｰ conf sys sdwan conf health-check conf sla edit 1 ･･････ edit 2 ･･････ ｰｰｰｰｰｰｰｰｰｰｰｰｰｰｰｰｰｰｰｰｰｰｰｰｰｰ sla_map=0x0 /// non-setting or 1&2 NG sla_map=0x1 /// 1 OK , 2 NG sla_map=0x2 /// 1 NG , 2 OK sla_map=0x3 /// 1&2 OK

This question depends how many targets were set which is not mentioned. If 3 targets were set then B is incorrect as 0x3 means it failed two targets, as one of the answers says that an interface missed three targets, in this rate I would have to choose CD

A-missed 1 B-missed 2 C-correct, 0x0, pg 316

This could be C&D, but the question is more around the health check and what has and has not passed, therefore I feel that B&C are correct, B could also be stated that T_MPLS has missed 1 target as well, that is if the assumption is there are 2 targets.

B & C are correct

Page 316 of the Study guide says, "Possible sla_map values for three SLA targets." It only showed value computation. Concerning the question here, I think the question only involves two (2) SLA Targets. T_MPLS sla_map=0x2, matches the 2nd SLA target T_INET_1 sla_map=0x1, matches the 1st SLA target but missed the 2nd SLA target T_INET_0 sla_map=0x3, matches the 1st and 2nd SLA target

B & C are correct: B - 0x1 means that only one target is matched and no matter how many targets are configured, one target at least was missed, thus the claim "T_INET_1 missed one target" is correct C - 0x0 also means that there are no targets configured D - claim can't be proven by the output.

B & D A. Wrong B. When there are two SLA targets 0x1 means that only the first sla target was met and the second one missed. 0x2 would mean second target was met while first one was missed. 0x3 would mean both sla targets were met. C. 0x0 means no targets were met ore there are no targets. Both ports have a latency over 20ms so this could be a sla target not met. D. These seem to be in order by jitter. There are two sla targets and if this would be in order by best quality then T_INET_0 should be the first one since it meets both targets.

This is a tricky one! Unless someone has taken the exam and confirm the correct answers (100% correct), there is room for dicussion. We don't know how many SLA targets are configured, so the sla map is the problem. If 2 targets are configured 0x1 means pass and fail, 0x2 fail and pass and 0x3 pass and pass. If its 3 targets its completly different. The same on Level3_DNS. 0x0 can also mean, that there is no SLA target configured - 7.2 Study_Gudie Page 316. So I would say B and D

7.2 study guide -

C and d

B and C are correct The D is not correct

C and D are correct. A is wring 0x3 means sla target 1 and SLA target are passed. B is wrong, 0x1 means sla target 1 is passed and target 2 and 3 are missed (if configured). C is correct. 0x0 means either target SLA are not configured or all SLA targets are missed. D is correct as SLA targets are ordered by jitter.
