When designing a WAN that will be carrying real-time traffic, what are two important reasons to consider serialization delay? (Choose two.)

• A.Serialization delays are variable because they depend on the line rate of the interface and on the type of the packet being serialized.
• B.Serialization delay is the time required to transmit the packet on the physical media.
• C.Serialization delay depends not only on the line rate of the interface but also on the size of the packet.
• D.Serialization delays are invariable because they depend only on the line rate of the interface.
• E.Serialization delays are variable because they depend only on the size of the packet being serialized.

Refer to the exhibit.

This new OSPF network has four areas, but the hub-and-spoke area experiences frequent flapping. In order to fix this design failure, which two mechanisms can you use to isolate the data center area from the hub-and-spoke area without losing Ip connectivity? (Choose two)

• A.Use OSPF distribute-list filtering on router A
• B.Make the data center area a NSSA
• C.Deploy a prefix summarization on router D
• D.Convert the data center area to EIGRP protocol
• E.Make the data center area totally stub

You are the lead IP network designer for a new service provider called XYZ, and you are working closely with the CTO to finalize design requirements. The CTO informs you that they want to transport IPv6 prefixes of customers through the XYZ network at this time; however, they need your advice on whether to deploy dual stack or MPLS 6PE/6VPE.
Which two options do you recommend? (Choose two.)

• A.Use MPLS 6PE to simplify the operation and keep a BGP-free core. When the LDPv6 becomes available, change to 4PE or keep the core using both IPv4 and IPv6. The main goal is to keep the core BGP-free and ensure that IPv4, IPv6, VPNv4, and VPNv6 are all label-switched.
• B.Prepare the dual-stack infrastructure from the beginning, even if BGP prefixes would have to be announced via IPv4 in case you decide to maintain the BGP-free core.
• C.Build a dual-stack network. Enable BGP in the core. Redistribute EBGP routes into IGP.
• D.Use MPLS 6VPE to simplify the operation and keep a BGP-free core. When the LDPv6 becomes available, change to 4PE or keep the core using both IPv4 and IPv6. The main goal is to keep the core BGP-free and ensure that IPv4, IPv6, VPNv4, and VPNv6 are all label-switched.
