ACME Agricultural requires that access to all network devices is granted based on identify validation, and an authentication server was installed for this purpose. Currently the network team uses a list of passwords based on regions to access the internal corporate network devices. Which protocol do you recommend to ensure identify validation from the authentication server to the corporate directory?

A.

HTTPS

B.

TACACS+

C.

SSH

D.

LDAP

Refer to the exhibit.

A customer currently has a large EIGRP-based network with several remote sites attached. All remote sites connect to the two corporate data centers, depicted as 10.1.1.0 and 10.1.2.0. The customer has experienced several network-wide failures where neighbors were stuck-in-active and had other network stability issues due to some links flapping. Which two redesign options increase stability and reduce the load on the remote site routers, still maintaining optimal routing between remote sites and the two data centers? (Choose two)

A.

Set the data center routers as stub-routers

B.

Perform summarization at the data centers, selectively leaking routes sent to the remote sites

C.

Perform summarization at the remote sites, selectively leaking routes sent to the data centers

D.

Set the hello interval timer to be larger than the hold interval

E.

Increase the hold interval to accommodate lost hello packets on error-prone links

Which options do you investigate first when designing fast network convergence?

A.

Routing protocol database size

B.

MTU of the involved interfaces

C.

Link speed between sites

D.

Supported Layer 3 failure detection mechanism

ACME Corporation is integrating IPv6 into their network, which relies heavily on multicast distribution of data. Which two IPv6 integration technologies support IPv6 multicast? (Choose two.)

A.

6VPE

B.

6PE

C.

dual stack

D.

ISATAP

E.

6to4

F.

IPv6INIP

Which two techniques are used in an OSPF network design to slow down the distribution of topology information caused by a rapidly flapping link? (Choose two)

SPF throttling

C.

IP event dampening

D.

Link-state incremental SPF

E.

Link-state partial SPF

Which mechanism provides fast path failure detection?

A.

Non-Stop Forwarding

B.

Carrier delay

C.

Graceful restart

D.

UDLD

E.

Fast hello packets

F.

iSPF

How can jitter be compensated on an IP network that carries real-time VoIP traffic with acceptable voice transmission quality?

A.

Set up VAD to replace gaps on speech with comfort noise

B.

Change CODEC from G.729 to G.711

C.

Deploy RSVP for dynamic VoIP packet classification

D.

Set up a playout buffer to play back the voice stream

Which IEEE standard is commonly used at the data link layer for an access network, in an IoT environment?

A.

Wireless Regional Area Network

B.

Low-Rate Wireless Network

C.

Wireless Local Area Network

D.

Broadband wireless metropolitan Network

In an Ethernet link containing five routers with OSPF network interface type configured as broadcast, how many OSPF adjacencies are established on this Ethernet link?

A.

7

B.

5

C.

10

D.

20

E.

6

Which native mechanism does OSPF use to prevent loops in MPLS VPNs?

A.

CE devices that run OSPF set the DN bit toward the PE router

B.

PE devices that run OSPF clear the DN bit toward the CE router

C.

CE devices that run OSPF clear the DN bit toward the PE router

D.

Creation of PE to PE OSPF sham link across the MPLS-created super backbone

E.

PE routers verify OSPF domain IDs used by CE OSPF processes

F.

PE devices that run OSPF set the DN bit toward the CE router
