CAE (CHAPTER 2 PART 2)

Which three computing services are specifically highlighted as being covered in Lesson 2 Part 1?

• Elastic Cloud Server (ECS), Image Management Service (IMS), Auto Scaling (AS)

• Bare Metal Server (BMS), Cloud Container Engine (CCE), Other Compute Services

• Virtual CPUs (vCPUs), Memory, Operating System (OS)

• Network Interface Card (NIC), Disk, Image

What are the fundamental components that constitute an Elastic Cloud Server (ECS)?

• Billing Mode, Region, Availability Zone (AZ), CPU

• Network Interface Card (NIC), Disk, Image, Memory, Network, Virtual CPU (vCPU)

• Independent cooling, fire extinguishing, moisture-proof, electricity facilities

• Professional hardware devices, virtual resources, security services

Which of the following is NOT an advantage of Elastic Cloud Server (ECS) related to scalability?

• Automatic adjustment of compute resources

• Flexible adjustment of ECS configurations

• Flexible billing modes

• Reliable data

What criteria are used to divide regions in Cloud Alpha Edge, and what is a characteristic of its operation?

• Number of physical data centers and type of CPU architecture; operated globally.

• Geographical location and network latency; only operated in Malaysia.

• Billing mode and image type; operated in multiple countries.

• Security group and EIP; operated in Southeast Asia.

What is a key characteristic of an Availability Zone (AZ)?

• It has high-latency and low-speed network connections to other AZs.

• It is a data center with the concept of a physical location.

• It is physically isolated and has independent wind, fire, and water resources.

• It typically has network latency greater than 10 ms and intra-region network latency of 1-10 ms.

In an ECS specification like "s2.medium.4", what does the digit '4' represent?

• The number of vCPUs.

• The generation name of the ECS.

• The ratio of memory to vCPUs.

• The type ID of the ECS.

What is the primary function of the Image Management Service (IMS)?

• To automatically allocate ECSs to different hosts within a group.

• To manage the entire lifecycle of your images.

• To configure network settings for an ECS.

• To reset the login password for an ECS.

Which type of image is created by a user and is visible only to that specific user?

• Public image

• Shared image

• Marketplace image

• Private image

What is the primary purpose of cross-region image replication in IMS operations?

• Converting between encrypted and unencrypted images.

• Enabling advanced features like fast ECS creation.

• Replicating a private image to the same account in another region for application deployment.

• Exporting private images to an OBS bucket for backup.

Which of the following is a limitation of encrypted images?

• They can be shared with other users but not published in the Marketplace.

• They cannot be shared with other users or published in the Marketplace.

• Their system disk cannot be encrypted.

• They cannot be used to create private images.
