Giv­en that users of the ap­pli­ca­tion lo­gin us­ing ap­pli­ca­tion cre­den­tials what AWS API call should be used by the ap­pli­ca­tion A) As­sume­Role­With­We­b­Iden­ti­ty B) As­sume­Role­With­I­AM C) As­sume­Role­With­SAML D) As­su­me­Ro­le .
A Server­less ap­pli­ca­tion uses API Gate­way to perform search­es. API Gate­way is con­fig­ured with a non proxy in­te­gra­tion to a back­ing lamb­da func­tion which queries Dy­namoDB. You need to en­sure that a search­String pa­ra­me­ter is in­clud­ed in the re­quest. What should you con­firm to en­sure this pa­ra­me­ter is re­quired? (Choose one) A) Con­fig­ure the in­te­gra­tion re­sponse B) Con­fig­ure the in­te­gra­tion re­quest C) Con­fig­ure the API Gate­way stage D) Con­fig­ure the method re­quest (E) con­trols the re­turn path, from in­te­gra­tion through API back back to the method.
Which of the fol­low­ing is the quick­est way to increase the CPU al­lo­ca­tion of a lamb­da func­tion? Choose one A) Change lamb­da run­time to one which sup­ports more CPU B) In­crease the CPU al­lo­ca­tion on the func­tion C) In­crease the mem­o­ry al­lo­ca­tion on a func­tion D) Change func­tion con­cur­ren­cy .
You have 5 cus­tom ap­plications run­ning on 5 EC2 in­stance.

Which of the state­ments below rep­re­sents a valid struc­ture for achiev­ing this (choose one) A) Set­up a Cloud­Watch met­ric name with a unique name­space for each ap­pli­ca­tion B) Set­up a Cloud­Watch di­men­sion with a unique name­space for each ap­pli­ca­tion C) Set­up a Name­space for the ap­pli­ca­tion with a unique met­ric for each ap­pli­ca­tion D)Set­up a unique di­men­sion for every ap­pli­ca­tion and de­liv­er into a cus­tom name­space.
You have con­nect­ed to an old EC2 in­stance which is run­ning an ap­pli­ca­tion you now main­tain. You run an AWS CLI com­mand and get an ac­cess denied mes­sage. When con­nect­ing to the EC2 console you no­tice there is no in­stance role at­tached. You cre­ate a role with the re­quired per­mis­sions, attach it to the in­stance and try and run the command again. What hap­pens? A) Not enough in­for­ma­tion to tell. B) The com­mand works C) The com­mand fails D) It de­pends on the role pri­or­i­ty val­ue .
Giv­en a val­ue of 10 WCU which of the state­ments be­low is cor­rect? (Choose all that ap­ply) A) You can write 10 1KB ITEMS B) You can write 20 1KB Even­tu­al­ly con­sis­tent Writes C) Writes can be even­tu­al­ly or strong­ly con­sis­tent D) Writes aren’t strong­ly or even­tu­al­ly con­sis­tent - they are just writes E) You can write 10 4KB ITEMS F) You can write 20 4KB Even­tu­al­ly con­sis­tent Writes.
You are look­ing to se­lect a tool for your mo­bile appli­ca­tion. The tool should be able to send a message to cus­tomer mo­bile phones when a new version of the ap­pli­ca­tion is avail­able in­clud­ing a link to down­load the new ap­pli­ca­tion or, de­pend­ing on plat­form gen­er­ate a push notif­ication to no­ti­fy the cus­tomer. What prod­uct should you sug­gest? (Choose one) A) Mo­bi­le Hub B) SQS C) SES D) SNS .
