What is a characteristic of the Cisco DMA Center Template Editor feature?

• A. It facilitates software upgrades lo network devices from a central point.
• B. It facilitates a vulnerability assessment of the network devices.
• C. It provides a high-level overview of the health of every network device.
• D. It uses a predefined configuration through parameterized elements or variables.

Answer: D

Explanation:
This is because the Cisco DNA Center Template Editor feature is a tool that allows the network administrator to create and deploy configuration templates to multiple network devices. The configuration templates use parameterized elements or variables, which are placeholders for values that can be customized for each device. For example, a variable can represent the hostname, IP address, or interface number of a device. The parameterized elements or variables can be defined manually or automatically using the Cisco DNA Center inventory. The source of this answer is the Cisco ENCOR v1.1 course, module 8, lesson 8.5: Implementing Network Configuration Management.

NEW QUESTION 6

What is the structure of a JSON web token?

• A. three parts separated by dots: header payload, and signature
• B. header and payload
• C. three parts separated by dots: version header and signature
• D. payload and signature

Answer: A

Explanation:
JSON Web Token (JWT) is an open standard (RFC 7519) that defines a compact and self-contained way for securely transmitting information between parties as a JSON object. This information can be verified and trusted because it is digitally signed. JWTs can be signed using a secret (with the
HMAC algorithm) or a public/private key pair using RSA or ECDSA.
JSON Web Tokens are composed of three parts, separated by a dot (.): Header, Payload, Signature. Therefore, a JWT typically looks like the following:
xxxxx.yyyyy.zzzzz
The header typically consists of two parts: the type of the token, which is JWT, and the signing
algorithm being used, such as HMAC SHA256 or RSA.
The second part of the token is the payload, which contains the claims. Claims are statements
about an entity (typically, the user) and additional data.
To create the signature part you have to take the encoded header, the encoded payload, a secret,
the algorithm specified in the header, and sign that. Reference: https://jwt.io/introduction/

• D. Uninterruptible power supply

Answer: D

Explanation:
This is because an uninterruptible power supply (UPS) is a device that provides backup power to a network device or a computer in case of a power outage or a power spike. A UPS can prevent data loss, corruption, or damage to the device by providing a smooth and continuous power supply. A UPS can also protect the device from power surges, brownouts, or voltage fluctuations.
