A. B. C. D. E.BD.
The answer choices given in this question refer to different file formats that are used to store software images for Cisco SD-WAN controllers. The correct answers are B. .qcow2 and E. .bin.
Here is a detailed explanation of the different image formats and their use in Cisco SD-WAN solutions:
A. .nxos: This file format is used for software images of Cisco Nexus switches, which are not directly related to SD-WAN controllers.
B. .qcow2: This is one of the supported image formats for Cisco SD-WAN controllers. It is a file format used for virtual machine images and is commonly used for cloud-based deployments. The QCOW2 file format is efficient in terms of storage space usage and allows for snapshot-based backups.
C. .iso: This file format is commonly used for software installation disks. It is not a supported image format for Cisco SD-WAN controllers.
D. .ova: This is another file format used for virtual machine images, and it stands for Open Virtualization Appliance. OVA files are used for packaging and distributing virtual appliances, which are pre-configured virtual machines that can be deployed on different virtualization platforms. While OVA files are used in some Cisco products, they are not a supported image format for Cisco SD-WAN controllers.
E. .bin: This is the other supported image format for Cisco SD-WAN controllers. It is a binary file format that contains the firmware or software code for the controller. .bin files are commonly used for updating or upgrading the software on network devices.
In summary, the two image formats supported for controller codes in Cisco SD-WAN solutions are .qcow2 and .bin.
