What is a disadvantage of the traditional three-tier architecture model when east west traffic between different pods must go through the distribution and core layers?

  1. low bandwidth
  2. security
  3. scalability
  4. high latency

Answer(s): A

Explanation:

Its about east-west traffic, latency would not be main concern, its the the bandwidth. 3-tier design inherently enforces to have less links on the core / distribution layer, & as the east-west traffic rapidly grows, we may ran out of ports on core/distriswitches(being only few switches, can't be added on the go)

A) Correct answer. Traffic aggregate to the link on core switch. Imagine 40 servers with 10Gbps for each, then core switch may need 400Gbps bandwidth but not exist now. So spine and leaf topology is introduced.
B) Incorrect. It is advantage on security for separating network.
C) Incorrect. It is advantage as you can add as much as switch you like. If you think heavy loading on core switch, then add another core switch as another tree.
D) Incorrect. Latency depend on distance, device and link performance. 3 layers design should be local and no distance problem. Device and link performance may be occurred due to traffic aggregration, but mentioned in A more appropriate.

Which solution component helps to achieve comprehensive threat protection and compliance for migration to multicloud SDX architectures?

  1. system-oriented architecture
  2. OSASE architecture
  3. platform-oriented architecture
  4. SASE architecture

Answer(s): D

Explanation:

SASE (Secure Access Service Edge) is a cloud-based security architecture that can help to achieve comprehensive threat protection and compliance for migration to multicloud SDX architectures. SASE combines the functionality of traditional security appliances, such as firewalls, VPNs, and web proxies, into a single cloud-based service. This makes it easier to manage and enforce security policies across multiple clouds and devices.

The other options are not as effective for achieving comprehensive threat protection and compliance for migration to multicloud SDX architectures. System-oriented architecture (SOA) is an architectural style that focuses on the interactions between different systems. OSASE (Open Security Architecture for the Enterprise) is an architecture that defines a set of security services that can be used to protect enterprise networks. Platform-oriented architecture (POA) is an architectural style that focuses on the use of common platforms to support different applications.



What are two descriptions of network optimization? (Choose two.)

  1. identify network requirements
  2. network redesign
  3. proactive network management
  4. network health maintenance
  5. maintain high availability

Answer(s): B,C

Explanation:

Optimize: Involves proactive management of the network. The goal of proactive management is to identify and resolve issues before they affect the organization. Reactive fault detection and correction (troubleshooting) is needed when proactive management cannot predict and mitigate failures. In the PPDIOO process, the optimization phase can prompt a network redesign if too many network problems and errors arise, if performance does not meet expectations, or if new applications are identified to support organizational and technical requirements.
