_Config_5x_chapter_010.pdf The Application Policy Infrastructure Controller (APIC) REST API is a programmatic interface that uses REST architecture. The API accepts and returns HTTP (not enabled by default) or HTTPS messages that contain JavaScript Object Notation (JSON) or Extensible Markup Language (XML) documents.
What is the primary purpose of a First Hop Redundancy Protocol?
A.
It allows directly connected neighbors to share configuration information.
B.
It allows a router to use bridge priorities to create multiple loop-free paths to a single destination.
C.
It reduces routing failures by allowing Layer 3 load balancing between OSPF neighbors that have the same link metric.
D.
It reduces routing failures by allowing more than one router to represent itself, as the
default gateway of a network.
It reduces routing failures by allowing more than one router to represent itself, as the
default gateway of a network.
What is the primary effect of the spanning-tree portfast command?
A. it enables BPDU messages
B. It minimizes spanning-tree convergence time
C. It immediately puts the port into the forwarding state when the switch is reloaded
D. It immediately enables the port in the listening state

When a site-to-site VPN is configured, which IPsec mode provides encapsulation and encryption of the entire original P packet?
A. IPsec tunnel mode with AH
B. IPsec transport mode with AH
C. IPsec tunnel mode with ESP
D. IPsec transport mode with ESP
Explanation:
“Encapsulating Security Payload…Unlike Authentication Header (AH), ESP in transport mode does not provide integrity and authentication for the entire IP packet. However, in Tunnel Mode, where the entire original IP packet is encapsulated with a new packet header added, ESP protection is afforded to the whole inner IP packet (including the inner header) while the outer header (including any outer IPv4 options or IPv6 extension headers) remains unprotected.
An engineer is configuring an encrypted password for the enable command on a router where the local user database has already been configured Drag and drop the
configuration commands from the left into the correct sequence on the right Not all commands are used
Which statement identifies the functionality of virtual machines?
A. Virtualized servers run most efficiently when they are physically connected to a switch that is separate from the hypervisor
B. The hypervisor can virtualize physical components including CPU. memory, and storage
C. Each hypervisor can support a single virtual machine and a single software switch
D. The hypervisor communicates on Layer 3 without the need for additional resources
How do TCP and UDP differ in the way that they establish a connection between two endpoints?
A. TCP uses synchronization packets, and UDP uses acknowledgment packets.
B. UDP uses SYN, SYN ACK and FIN bits in the frame header while TCP uses SYN, SYN ACK and ACK bits
C. UDP provides reliable message transfer and TCP is a connectionless protocol
D. TCP uses the three-way handshake and UDP does not guarantee message delivery-
