Which new construct must a user create when configuring in-band management?
When configuring in-band management, a new construct that often needs to be created is the management contract. A management contract is a logical construct that defines the communication rules or policies between Endpoint Groups (EPGs). This construct is essential for enabling and controlling communication in the management network. Other elements like the bridge domain and management tenant typically have pre-existing configurations or default constructs that can be utilized, whereas the management contract is a new configuration identified explicitly for defining communication policies.
Shouldn't this be A - VLAN pool?
A is correct, since Tenant and Bridge Domain are present by default on the GUI. https://www.cisco.com/c/en/us/td/docs/switches/datacenter/aci/apic/sw/4-x/basic-configuration/Cisco-APIC-Basic-Configuration-Guide-411/Cisco-APIC-Basic-Configuration-Guide-411_chapter_0100.html#task_730EB317BDE94145BAF91092F88B5257
Agree, should be A as for the rest of the constructs a default one should already exist that you can use
Shuldn't be B (management contract), since VLAN Pool is not created. Is it assigned only one VLAN ID when in in-band mgmt EPG is created.
Correct answer should be B. Both a contract and VLAN pool should be created however the questions specifies "construct" and the only logical construct among VLAN pool and contrats is the latter.
This is not D, Correct answer is B. Bridge domain "inb" is pre-defined within the management tenant. As per Red Nectar Article - "I’ll assign the default gateway IP address to the pre-defined inb Bridge Domain in the mgmt Tenant". https://rednectar.net/2016/12/22/configuring-in-band-management-for-the-apic-on-cisco-aci-part-1-via-an-epg/ I can confirm this is correct within own lab environment.
inb (Bridge domain pre existing). No Vlan pool and ideally one of the first steps required. MGMT tenant exists. Management contract is the last "to do". Construct literally means build blocks. Hence nothing can be built with thr VLANS.
should be B
Vlan Pool is not a construct ,but still required.So i’d say B
A should be the right answer, the contract required for external communication of In-band,
A contract is a policy construct used to define communication between EPGs. https://www.cisco.com/c/en/us/solutions/collateral/data-center-virtualization/application-centric-infrastructure/white-paper-c11-743951.html
In Cisco ACI, the typical components involved in configuring in-band management include a management tenant, management VRF, bridge domain for management, VLAN pool, and the assignment of IP addresses to the in-band interfaces of the fabric devices (APICs, leaf nodes, and spine nodes). A "management contract" is more commonly associated with defining the communication rules or policies for managing the ACI fabric, but it is not directly related to the creation of the necessary constructs for in-band management
It's physical domain then vlan pool
D is correct, pls refer link: https://www.cisco.com/c/en/us/td/docs/switches/datacenter/aci/apic/sw/4-x/basic-configuration/Cisco-APIC-Basic-Configuration-Guide-411/Cisco-APIC-Basic-Configuration-Guide-411_chapter_0100.html#task_730EB317BDE94145BAF91092F88B5257
in the same link you have provided, watch closely it does Not mention "Create Bridge Domain", it only says expand the bridge domain(which must mean it is pre-existing). please correct me if my observation is incorrect...
Built-in BD name is "inb" in the mgmt tenant. No need to create.
Why is it not a bridge domain, it also needs to be created?
