Cisco 300-620 Online Questions & Answers

• Question 361:

  A Cisco ACI fabric has 10 standalone leaf switches. The requirement is for the APIC to select the odd switches as a VPC group and select even switches as another VPC group automatically. Which VPC protection type must be configured to accomplish this goal?

  C. reciprocal
  D. explicit
  D. explicit

• Question 364:

  Refer to the exhibit.

  

  A Cisco ACI environment hosts two e-commerce applications. The default contract from a common tenant between different application tiers is used, and the applications work as expected. The customer wants to move to more specific contracts to prevent unwanted traffic between EPGs. A network administrator creates the app-to-db contract to meet this objective for the application and database tiers. The application EPGs must communicate only with their respective database EPGs. How should this contract be configured to meet this requirement?

  A. Set the app-to-db scope to Global.
  B. Set the app-to-db scope to Application Profile.
  C. Implement the app-to-db scope as VRF.
  D. Implement the app-to-db as a Taboo contract.
  B. Set the app-to-db scope to Application Profile.

  ---

  Explanation/Reference:

  A contract will only program rules between EPGs that are defined within the same application profile. Use of the same contract across other application profile EPGs will not allow for crosstalk between them.

• Question 365:

  An engineer is extending an EPG out of the ACI fabric using static path binding. Which statement about the endpoints is true?

  A. Endpoints must connect directly to the ACI leaf port.
  B. External endpoints are in a different bridge domain than the endpoints in the fabric.
  C. Endpoint learning encompasses the MAC address only.
  D. External endpoints are in the same EPG as the directly attached endpoints.
  D. External endpoints are in the same EPG as the directly attached endpoints.

  ---

  Explanation/Reference:

  The user can extend an EPG beyond an ACI leaf by statically assigning a leaf port (along with a VLAN ID) to an EPG. After doing so, all the traffic received on this leaf port with the configured VLAN ID will be mapped to the EPG and the configured policy for this EPG will be enforced. The endpoints need not be directly connected to the ACI leaf port. They can be behind a layer 2 network as long as the VLAN associated with the EPG is enabled within the layer 2 network that connects the remote endpoint to the ACI fabric.

• Question 366:

  Which requirement must be met for the inter-pod network when connecting a remote leaf to a Cisco Application Centric Infrastructure fabric?

  A. less than 150ms end-to-end latency
  B. dynamic host configuration protocol relay configuration on the upstream router
  C. multicast bidirectional PIM support D. border gateway protocol underlay for VTEP reachability
  B. dynamic host configuration protocol relay configuration on the upstream router

• Question 367:

  In the context of ACI Multi-Site, when is the information of an endpoint (MAC/IP) that belongs to site 1 advertised to site 2 using the EVPN control plane?

  A. Endpoint information is not exchanged across sites unless COOP protocol is used.
  B. Endpoint information is not exchanged across sites unless a policy is configured to allow communication across sites.
  C. Endpoint information is exchanged across sites as soon as the endpoint is discovered in one site.
  D. Endpoint information is exchanged across sites when the endpoints are discovered in both sites.
  B. Endpoint information is not exchanged across sites unless a policy is configured to allow communication across sites.

  ---

  Explanation/Reference:

  The endpoint information is stored in the local COOP database. Spine nodes in site 1 know about locally connected endpoints, and the same is true for spine nodes in site 2. Note that at this point no information is exchanged across sites for EP1 and EP2 EPGs, because there is no policy in place yet indicating a need for those endpoints to communicate.

  An intersite policy is defined in Cisco ACI Multi-Site Orchestrator and is then pushed and rendered in the two sites.

• Question 368:

  An engineer must add new servers to a Cisco ACI cluster and configure ports to accept the new servers. The existing servers are dual-homed to Leaf101 and Leaf102 using ports 1-3 and an interface policy group called cluster1_ifpg. The new servers must use ports 1 and 2 on Leaf103 and Leaf104. Which two actions must be taken to enable the ports with the same configuration as the existing servers in the cluster? (Choose two.)

  A. Attach interface selectors to leaf profiles Leaf103 and Leaf104.
  B. Use interface selector for cluster1_infpg.
  C. Connect with interface selector using a new AEP.
  D. Configure interface selector using a new interface policy group.
  E. Select ports 1 and 2 using interface selectors.
  A. Attach interface selectors to leaf profiles Leaf103 and Leaf104.
  E. Select ports 1 and 2 using interface selectors.

• Question 369:

  A Cisco ACI fabric has three different endpoints S1, S2, and S3. These endpoints must communicate with each other without contracts. These objects have been created in APIC:

  1.

  Two EPGs named DNS_EPG and Database_EPG

  2.

  Two application profiles. PROD_App and Data_App

  3.

  Two bridge domains DNS_BD and Database_BD

  4.

  PROD_APP and Database_BD mapped to Tenant PROD

  5.

  Data_App and DNS_BD mapped to Tenant Data

  Which set of actions completes the fabric configuration?

  A. Add S1, S2, S3 under Database_EPG. MAP Database_EPG under PROD_ App. Associate Datbase_EPG with DNS_BD.
  B. Add S1, S2, S3, under DNS_EPG. MAP DNS_EPG to Data_App. Associate DNS_EPG with Dns_BD.
  C. Add S1, S2, S3 under DNS_EPG. MAP DNS_EPG to Data_App. Associate DNS_EPG with Database_BD.
  D. Add S1, S2, S3 under Database_EPG. MAP Database_EPG under Data_App. Associate Datbase_EPG with Database_BD.
  C. Add S1, S2, S3 under DNS_EPG. MAP DNS_EPG to Data_App. Associate DNS_EPG with Database_BD.

• Question 370:

  An engineer must configure a group of servers with a contract that uses TCP port 80. The EPG that contains the web servers requires an external Layer 3 cloud to initiate communication. Which action must be taken to meet these requirements?

  A. Configure the EPG as a provider and L3 out as consumer of the contract.
  B. Configure OSPF to exchange routes between the L3 out and EPG.
  C. Configure a taboo contract and apply it to the EPG.
  D. Configure the EPG as a consumer and L3 out as a provider of the contract.
  A. Configure the EPG as a provider and L3 out as consumer of the contract.
