vered more than once, but must be delivered in the order that they have arrived, and also must allow for efficient, repeated polling of the queue. Which of the following options are most suitable?a. Configure a standard SQS queue and use long polling
b. Configure a FIFO SQS queue and enable long polling

Answer:

Option B is the correct option.

Explanation:

When using SQS the user request to separate a query. The specification specifies that updates on the list may have been transmitted multiple times, but it must be transmitted throughout the sequence in which they appeared, and therefore should require secure, repetitive queue polling.

So, They configure a First In First Out SQS queue and allow long-polling which is suitable for AWS services.

Two Technicians are discussing ShopKey Pro. Technician
Vlada [557]

Answer:

Technician A is correct

Explanation:

Contact us is the most common term used in online applications such as in websites, mobile/android application to search contact information. People mostly scanning the “contact us” page to find the contact information, if they want to contact the company or organization.

Why technician A is correct.

Technician A is correct because people always try to find the “Contact us” page to find contact information for asking questions, to provide feedback, or any suggestion if they want to provide. It is hard for people to find contact information to provide feedback or give an idea to improve the ShopKey version in “support” heading under the “help” section. Because people are more inclined to search such information in the “Contact us” page rather than exploring the website to find such contact.

Why technical B is not correct

When people want to provide feedback, ask a question or suggest a new idea, they mostly prefer to search for information in the contact us pages. An ordinary user, who has no knowledge of website management or website hierarchy, search contact information in the “Contact us” page rather than searching in support or in the help section.

[Assembly Language]Extended Subtraction Procedure.Create a procedure named Extended_Sub --(Receives: ESI and EDI point to the tw
alex41 [277]

Answer:

Modern (i.e 386 and beyond) x86 processors have eight 32-bit general purpose registers, as depicted in Figure 1. The register names are mostly historical. For example, EAX used to be called the accumulator since it was used by a number of arithmetic operations, and ECX was known as the counter since it was used to hold a loop index. Whereas most of the registers have lost their special purposes in the modern instruction set, by convention, two are reserved for special purposes — the stack pointer (ESP) and the base pointer (EBP).

For the EAX, EBX, ECX, and EDX registers, subsections may be used. For example, the least significant 2 bytes of EAX can be treated as a 16-bit register called AX. The least significant byte of AX can be used as a single 8-bit register called AL, while the most significant byte of AX can be used as a single 8-bit register called AH. These names refer to the same physical register. When a two-byte quantity is placed into DX, the update affects the value of DH, DL, and EDX. These sub-registers are mainly hold-overs from older, 16-bit versions of the instruction set. However, they are sometimes convenient when dealing with data that are smaller than 32-bits (e.g. 1-byte ASCII characters).

When referring to registers in assembly language, the names are not case-sensitive. For example, the names EAX and eax refer to the same register.

KIM [24]

Answer:

Please find the attachment of the code file and its output:

Explanation:

In the first code, two variable "a, b" is defined that holds dictionary value which is defined in the question, in the next step a for loop is declared that hold dictionary key and value and use a method set to check the value is available in the dictionary and use print method to print its value.

In the second code, a package counter is an import as the c for count value, in the next step a variable a is declared, that uses a counter method to hold a dictionary value in its parameter, and in the print method, it uses sort method to print its value.

Ray Of Light [21]

Impact sockets are sockets used to cope with the vibration caused by the impact of the hammer on the anvil. Both technicians are right. It is true that impact sockets have thicker walls than conventional sockets, so technician A is right. But it is also true that impact sockets have a black oxide finish, so the technician B is also right.
