Single-Selection Questions

Multiple-Selection Questions

  • Client-side: CDN is the best choice; the network will not impact the cache. Option ‘a’ is Right
  • Server-side: There is ECS for computing, RDS for Database, and SLB for load balancing. SLB just balances the load, so if there is CDN, the bandwidth will not be the main cause. Option ‘c’ is Wrong
  • EIP on ECS (This is not applicable as per the given scenario)
  • NAT Gateway. NAT Gateway has two functions, SNAT and DNAT. SNAT from ECS to connect to outside internet and DNAT from outside internet to access to ECS. (For the given scenario, users need to access ECS over the internet. Hence, it is the DNAT function. Option ‘b’ is Right and Option ‘c’ is Wrong
  • EIP on SLB (Option ‘d’ fulfills this criterion, but option ‘a’ doesn’t mention binding the EIP to SLB instance.) A is wrong. Option ‘d’ is Right and Option ‘a’ is Wrong
