A customer has a requirement to deploy a cloud service and needs to have full control over the underlying OS, data and applications.
Which cloud model meets this requirement?

  1. MaaS
  2. PaaS
  3. SaaS
  4. IaaS

Answer(s): D

Explanation:

Traditional IT is responsible for Application, Data, Runtime, Middleware, OS, Virtualization, Servers, Storage, Networking.
IaaS = Infrastructure as a Service ג€" The customer is responsible for OS, Virtualization, Servers, Storage, Networking.
SaaS = Software as a Service - The software is deployed by the cloud provider ג€" Customer is responsible for nothing.
PaaS = Platform as a Service - Software can be deployed by the customer building their own application | is responsible for Data and Application.



Refer to the exhibit.
A flapping link issue has been reported on the vPC keepalive link. A packet capture has been activated on the Cisco Nexus switch.
What is the destination IP address of the vPC keepalive packets that are sent by the switch?

  1. 192.168.254.4
  2. 192.168.254.1
  3. 192.168.254.2
  4. 239.255.70.83

Answer(s): A

Explanation:

3200 is the default UDP port for keepalive packets. Just look for the first line with port 3200 and note the destination IP, which is 192.168.254.4.

Due to a major version change, an engineer must perform a software upgrade on a Cisco Nexus Series switch.
Which two technologies should be implemented to reduce disruptions to the network during the upgrade? (Choose two.)

  1. vPC
  2. HSRP
  3. VDC
  4. MLAG
  5. PAgP

Answer(s): A,B

Explanation:

vPC leverages both hardware and software redundancy aspects:
ג— vPC uses all port-channel member links available so that in case an individual link fails, hashing algorithm will redirect all flows to the remaining links.
ג— vPC domain is composed of two peer devices. Each peer device processes half of the traffic coming from the access layer. In case a peer device fails, the other peer device will absorb all the traffic with minimal convergence time impact.
Best Practices for HSRP/VRRP and vPC
This section describes best practices for using HSRP (Hot Standby Router Protocol) or VRRP (Virtual Router Redundancy Protocol) with vPC.
HSRP/VRRP active/active with vPC
ג€¢ HSRP (Hot Standby Router Protocol) and VRRP (Virtual Router Redundancy Protocol) are both network protocols that provides high availability for servers IP default gateway.
ג€¢ vPC domain at aggregation layer usually performs L2/L3 boundary so each vPC peer device is configure with interface VLAN (or SVI) and HSRP or VRRP runs on top of this interface.
ג€¢ HSRP and VRRP in the context of vPC have been improved from a functional and implementation standpoint to take full benefits of the L2 dual-active peer devices nature offered by vPC technology.

Refer to the exhibit.
What is the result of running the command presented?

  1. Multicast traffic forwarding is suspended.
  2. MRIB is flushed.
  3. The PIM database is deleted.
  4. PIM join messages are suspended.

Answer(s): C

Explanation:

When you restart PIM, the following tasks are performed:
✑ The PIM database is deleted.
✑ The MRIB and MFIB are unaffected and forwarding of traffic continues.
✑ The multicast route ownership is verified through the MRIB.
✑ Periodic PIM join and prune messages from neighbors are used to repopulate the database.

Refer to the exhibit.
What is the reason the system-fm-vrrp checkpoint was created?

  1. The VRRP process crashed and the checkpoint was automatically created.
  2. The VRRP service restarted and the checkpoint was automatically created.
  3. The network administrator manually created it.
  4. The VRRP-enabled feature has been disabled.

Answer(s): D

Explanation:

Reasons that could trigger automated system checkpoints are highlighted below:
✑ License expiration of a feature
✑ Disabling a feature with the no feature command
✑ Removing an instance of a Layer 3 protocol
The system-generated checkpoint name convention has the format system-fm-feature. To help illustrate this automated feature we attempted to disable the VRRP feature on our Nexus 5000 therefore triggering the system to create a checkpoint. First we confirm the VRRP feature is enabled by issuing the show feature | include vrrp command then disable it and then verify it has been disabled:

Notice that the system now shows a second checkpoint system-fm-vrrp which did not previously exist. This second checkpoint was created automatically by the
Nexus as soon as we disabled the vrrp feature.
