• Question 2:

  Feature-rich networks are complex network models that provide one or more features in addition to the network topology. In attributed networks, attributes are assigned to the nodes to describe the corresponding entities. For example, in a friendship network, the actors can be described by their genre and their age.

  Which two alternative network models can be used to model interaction over time or to model each attribute by a specific relationship? (Choose two.)

  A. information network
  B. heterogeneous network
  C. temporal network
  D. probabilistic network
  E. multilayer network
  F. location-aware network
  C. temporal network
  E. multilayer network

  A. Hot-potato routing is the preferred architecture when connecting to content providers
  B. Hop-potato keeps traffic under the control of the network administrator for longer
  C. OSPF uses hot-potato routing if all ASBRs use the same value for the external metric
  D. Hot-potato routing is prone to misconfiguration as well as poor coordination between two networks
  A. Hot-potato routing is the preferred architecture when connecting to content providers

• Question 4:

  A. Transport Mode in IPsec Phase I
  B. Transport Mode in IPsec Phase II
  C. Tunnel Mode in IPsec Phase II
  D. Tunnel Mode in IPsec Phase I
  B. Transport Mode in IPsec Phase II

• Question 7:

  You want to add 900 VLANs to the existing 90 VLANs on a data center Which two spanning-tree concerns must you consider? (Choose two )

  A. STP is increased by a factor of 10 convergence time
  B. To add 990 VLANs to the switching hardware reserved VLANs requires you to use extended VLAN
  C. The diameter of the STP topology is increased.
  D. The PVST+ increases CPU utilization
  E. BPDU does not support 990 VLANs
  C. The diameter of the STP topology is increased.
  D. The PVST+ increases CPU utilization

• Question 8:

  Identity and access management between multiple users and multiple applications has become a mandatory requirement for Company XYZ to fight against ever increasing cybersecurity threats. To achieve this, federated identity services have been deployed in the Company XYZ network to provide single sign-on and Multi-Factor Authentication for the applications and services. Which protocol can be used by Company XYZ to provide authentication and authorization services?

  A. OAuth2
  B. OpenID Connect
  C. OpenID
  D. SAML2.0
  D. SAML2.0

• Question 9:

  Refer to the exhibit.

  

  Company XYZ BGP topology is as shown in the diagram. The interface on the LA router connected toward the 10 1.5.0/24 network is faulty and is going up and down, which affects the entire routing domain. Which routing technique can the network administrator use so that the rest of the network is not affected by the flapping issue?

  A. The LA administrator should use route aggregation to summarize the 10 1 4.0/24, 10 1 5 0/24, 10.1.6.0/24, and 10 1 7 0/24 networks toward Chicago
  B. The LA administrator should use route dampening for the 10.1.5 0/24 network so that it does not get propagated when it flaps up and down.
  C. The LA administrator should use route filtering to block the 10.1.5.0/24 network from getting propagated toward Chicago and New York.
  D. The Chicago administrator should use route filtering to block the 10.1.5.0/24 network from coming in from the LA router.
  A. The LA administrator should use route aggregation to summarize the 10 1 4.0/24, 10 1 5 0/24, 10.1.6.0/24, and 10 1 7 0/24 networks toward Chicago

• Question 10:

  1.CAPEX planning is driven by technology and not by business objectives.

  2.The CAPEX planning team lacks the data it needs to perform due diligence tasks.

  3.The organizational structure lacks sufficient accountability and incentives.

  Which corporate cultural change contributes to improving the effectiveness of CAPEX spending?

  A. Build a financial control function that delivers high-quality reports on operational expenses for business insight and financial reporting.
  B. CxO-level staff must have a full technical understanding but the should not trust their technical leaders fully.
  C. Adopt new organizational models that promote real accountability for ROI. not just revenue. EBITDA, and cash.
  D. Marketing and product management divisions must reduce their CAPEX budgets significantly to drive the change.
  C. Adopt new organizational models that promote real accountability for ROI. not just revenue. EBITDA, and cash.
