Question 5

The PaaS model provides customers with a virtualized application development platform without the need for them to furnish hardware or system administration using in-house resources All necessary infrastructure components and application development services are provided and managed by the cloud service provider.
Which limitation should be considered when selecting PaaS model?

A. compatibility with existing development environments

B. loss of customer control

C. limited customization options

D. potential network latency

Correct Answer: C

Question 6

Refer to the exhibit. A customer needs to implement a connectivity model by using one active link for inbound and outbound traffic and a second link for backup. The backup link is low speed and is required only during outages of the primary link. Which design solution should be implemented?

A. Advertise more specific routes to ISP 1. Increase the local preference attribute of inbound BGP from ISP1.

B. Advertise a longer AS PATH to ISP 2. Increase the MED to ISP 2.

C. Advertise less specific routes to ISP 2. Increase the AS PATH inbound from ISP 1.

D. Advertise a higher local preference to ISP 2. Increase the AS PATH inbound from ISP 1.

Correct Answer: B

Question 7

Company XYZ is running a redundant private WAN network using OSPF as the underlay protocol. The current design accommodates for redundancy in the network, but it is taking over 30 seconds for the network to reconverge upon failure. Which technique can be implemented in the design to detect such a failure in a subsecond?

A. BFD

B. STP

C. OSPF LFA

D. flex links

E. fate sharing

Question 9

The Layer 3 control plane is the intelligence over the network that steers traffic toward its intended destination Which two techniques can be used in service provider-style networks to offer a more dynamic, flexible, controlled, and secure control plane design? (Choose two.)

A. remote black-holing trigger

B. prefix lists

C. QoS policy propagation with BGP

D. access control lists

E. firewalls

Correct Answer: A,C

Question 10
