Which option does best practice dictate for the maximum number of areas that an OSPF router should belong to for optimal performance?

An engineer is attempting to improve OSPF network performance and discovers that the entire SPT recomputes whenever a type 1 or type 2 LSA is received within
an area.

Which action can optimize SPT operations?

Which action can be taken on a multiaccess segment with OSPF speakers to reduce the performance impact during widespread convergence events?

Which two design principles should be followed to scale EIGRP properly? (Choose two.)

A campus network utilizes EIGRP to connect to several remote branch offices.
Which configuration should be established on all branch routers to improve routing scalability and performance?

What are three primary components in IS-IS fast convergence? (Choose three.)

A network design engineer has been asked to reduce the size of the SPT on an IS-IS broadcast network. Which option should the engineer recommend to
accomplish this task?

Summary address blocks can be used to support which network application?

An organization is designing the IP allocation of a new site. It currently has 12 separate IP segments. Each segment must be /24, accommodate 25% of growth,
and be easily summarized.
Which summarized IP block can be subnetted to meet these requirements?

Refer to the exhibit.

A customer requires a web application implementation, but the web server has communication only to the application server and users, and the
database server has communication only to the application server. What firewall design is the best fit for this scenario?
