Select Two (Multi-Select) Questions

SNMPv3

Why wrong: SNMPv3 is used for SNMP management, not REST APIs.

SSH Key

Why wrong: SSH keys are used for device access, not REST API authentication.

RADIUS

Why wrong: RADIUS is for network access authentication, not API calls.

As a Kubernetes Secret

Why wrong: Secrets are a separate resource for sensitive data, not for ConfigMap.

As a container image label

Why wrong: Labels are metadata, not for runtime configuration.

git reset --hard HEAD

Why wrong: This resets all files and the index, discarding all changes, but it affects the entire repository, not just one file.

git stash drop

Why wrong: This drops the latest stash, not relevant to discarding changes to a specific file.

git revert <file>

Why wrong: 'git revert' is for undoing commits, not discarding local changes.

Model is dependent on the View.

Why wrong: Model independent.

Model represents the user interface.

Why wrong: Model is data.

View directly modifies the Model.

Why wrong: View does not modify Model.

offset and limit parameters

Why wrong: Offset/limit are not used by Meraki.

page and perPage query parameters

Why wrong: Meraki does not use page numbers.

Retry-After header

Why wrong: Retry-After is for rate limiting, not pagination.

junos_config

Why wrong: For Juniper Junos.

nxos_command

Why wrong: For NX-OS devices.

eos_config

Why wrong: For Arista EOS.

Writing scripts that only push incremental configurations.

Why wrong: Incremental pushes may not be idempotent without state awareness.

Relying on manual rollback procedures after automation failures.

Why wrong: Manual rollback does not ensure idempotent automation.

CSV

Why wrong: CSV is not typical for REST APIs.

HTML

Why wrong: HTML is for web pages, not API data exchange.

Page size is fixed at 1000 items per page.

Why wrong: Page size is not fixed; it can vary.

Pagination is optional and disabled by default.

Why wrong: Pagination is always used; results are paginated by default.

Pagination requires the use of OAuth tokens.

Why wrong: Pagination is unrelated to authentication.

Operator custom resources.

Why wrong: Used to manage custom applications, not general config.

Environment variables in the Dockerfile.

Why wrong: Baked into the image, not manageable by Kubernetes.

Know your network

Why wrong: This category is for read operations like device list and topology.

Run your network

Why wrong: Includes command runner and path trace, not configuration deployment.

Event notifications

Why wrong: Event notifications are under Platform but are not for deploying changes.

IPv6 addresses are 32 bits in length.

Why wrong: IPv6 addresses are 128 bits.

IPv6 uses ARP to resolve MAC addresses.

Why wrong: IPv6 uses Neighbor Discovery Protocol (NDP) instead of ARP.

YANG models are always written in XML syntax.

Why wrong: YANG has its own syntax, not XML; models can be translated to XML.

YANG is a replacement for SNMP.

Why wrong: YANG complements but does not replace SNMP.

Client certificate exchange

Why wrong: Not commonly used with Cisco APIs.

LDAP bind credentials

Why wrong: LDAP is for directory services, not typical for API auth.

SNMPv3 authentication

Why wrong: SNMP is separate from REST API auth.

API key

Why wrong: API key is a separate authentication method, not OAuth 2.0.

Why wrong: Basic is an HTTP authentication scheme, not an OAuth 2.0 grant.

Implicit grant

Why wrong: Implicit is deprecated in OAuth 2.0 Security BCP.

255.255.255.224 (/27)

Why wrong: Incorrect. /27 provides only 30 usable host addresses, which is insufficient for 50 hosts.

255.255.255.248 (/29)

Why wrong: Incorrect. /29 provides only 6 usable host addresses, insufficient.

255.255.255.240 (/28)

Why wrong: Incorrect. /28 provides only 14 usable host addresses, far below the requirement.

for iface in interfaces.keys(): print(iface + ': ' + interfaces.get(iface))

Why wrong: Incorrect: Does not skip None, so prints 'None' as a string for entries with None IP.

for iface in interfaces: if interfaces[iface]: print(iface, ':', interfaces[iface])

Why wrong: Incorrect: Uses truthiness check which could skip non-None falsy values, and print with commas produces spaces around the colon (e.g., 'iface : ip'), deviating from expected format.

Automatically enforce QoS policies on switches.

Why wrong: Assurance is for monitoring, not enforcement.

Collect NetFlow data from all network devices.

Why wrong: Assurance uses multiple data sources, not just NetFlow.

It supports multiplexing of multiple streams.

Why wrong: Multiplexing is a feature of HTTP/2, not TLS.

It is an application layer protocol like HTTP.

Why wrong: TLS is a transport layer security protocol that runs between transport and application layers.

It uses port 443 by default.

Why wrong: Port 443 is the default for HTTPS, not a TLS property.
