During an upgrade of an existing data center, a network team must design segmentation into existing networks. Due to legacy applications, the IP addresses cannot change. Which firewall deployment model meets these requirements?

B. multicontext mode

below says commonly deployed in VRF’s which solves the use case above of not needing to change IP address and designing segmentation into an existing network.

Firewall virtualization is mainly used in data center networks. The advantage of using
firewall virtualization is scalability and flexibility. The use of automation tools can also
reduce the operational workload and costs.
There are two types of firewall virtualization:
■ Multicontext mode: Virtualized firewalls run on a single physical ASA appliance.
■ Virtual firewalls: Virtual firewalls are software-only firewalls running in a
hypervisor (virtual machine’s manager).
The multicontext mode was originally designed for multitenant deployments. It is also
commonly deployed in virtual routing and forwarding (VRF) environments, where
VLANs map to VRFs, and each VRF has its own virtual firewall

You can implement all security context in routed mode or transparent mode, or you can
implement some contexts in routed mode and some in transparent mode

@ast

An organization is using a link state routing protocol that is not dependent on IP addressing. Which action should be taken to enable routing across area boundaries in this environment?
A. Assign Level 1 router interfaces to different areas
B. Assign Level 2 routers to different areas
C. Assign Level 1 routers to different areas
D. Assign Level 2 router interfaces to different areas
E. Assign Level 2 router interface to the backbone area
F. Assign Level 1 router interface to the backbone area

ANS B. Assign Level 2 routers to different areas, read up on ISIS

@MDF

Are we saying we just we want to segment, there is no connectivity between segments, if we are splitting two servers on the same network segment them mutlicontext would achieve, but we are not going to get communication work between the two servers without natting. Am I overthinking this?

In ISIS the router needs to be L1 and/or L2 capable for inter-area, however you also configure the interfaces to be L1 or L2 to define that, so for a single answer I would select D.

@anonymous, yes you might be overthinking this. Transparent mode does not segment just filters traffic.

source figure 1
cisco.co*m/c/en/us/td/docs/security/asa/asa95/configuration/general/asa-95-general-config/intro-fw.html
The following figure shows a typical transparent firewall network where the outside devices are on the same sub-net as the inside devices

@MDF, I would have selected routed, not transparent anyway.

But why multi-context over routed?

If you have three network seqments. If the 10.1.1.0/24 could application servers, 10.1.2.0/24 could be, databases, and 10.1.3.0/24 webservers. you could run this in routed mode. If you wanted separate out multiple application with associated databases and webservers, I could see how mutli-context would help here.

I think the question does not have enough detail on the goals they want to achieve for me to 100% say routed or multi-context. Hope I do not get this one.

Has anyone seen the portals D&D? I saw that on my exam the last time I took the exam and failed.

it’s great this page is rocking again !! For many months it was poison and absolute rotten.

Hi @anonymous this question i looked at the exam guide and found this this topic under security services (5.1.e multiple context)which makes up 13% of the questions. I recently took the test scored 9xx and in this section scored 8x%. This one question won’t kill you but I read about multi context. It’s independent of routed mode vs transparent . Your ASA is either in single context mode or multiple context mode.

1st Requirements – design segmentation into existing network = VRF’s is the solutions.
2nd requirement – IP address cannot change – VRF’s also solve this

Below is quoted direct from the Arch book as I mentioned above
“The multicontext mode was originally designed for multitenant deployments. It is also
commonly deployed in virtual routing and forwarding (VRF) environments, where
VLANs map to VRFs, and each VRF has its own virtual firewall
You can implement all security context in routed mode or transparent mode, or you can
implement some contexts in routed mode and some in transparent mode”

In your example you mentioned routing between segments. Multicontext does not take your ability away to do this?

Source “cisco.com/c/en/us/td/docs/security/asa/asa90/configuration/guide/asa_90_cli_config/ha_contexts.html#75590”
Common Uses for Security Contexts
You might want to use multiple security contexts in the following situations:

You are a service provider and want to sell security services to many customers. By enabling multiple security contexts on the ASA, you can implement a cost-effective, space-saving solution that keeps all customer traffic separate and secure, and also eases configuration.
routing are not supported.”

Notice last line cost effect solution to Separate customer traffic
Use existing device to segment the network

An engineer must ensure Layer 2 extension capabilities over any transport infrastructure. Which inter
connective data center functionality satisfies this requirement?
A. EoMPLS
B. Private line
C. OTV
D. VPLS
Should i consider Answer is C: OTV (due to over any transport infra).

@MDF i get it, its one of the Cisco questions where you could built a valid case for both with reasons why. Enterprise versus SP. On various dumps I have seen all three modes as valid answers and supported documentation.

This q seems to around for about 12 months now, just hope I do not get this one.

On one dump seen two questions very similar

QUESTION 31
During an upgrade of an existing data center, a network team must design Segmentation into existing
network. Due to legacy applications, the IP address cannot change. Which firewall deployment model
meets these requirements?
A. cluster mode
B. routed mode
C. multicontext mode
D. transparent mode
Correct Answer: C

QUESTION 34
A customer would like to implement a firewall to secure an enterprise network. However the customer is
unable to allocate any new subnets. What type of firewall mode must be implemented?
A. transparent
B. routed
C. virtual
D. zone based
E. active/active
F. active/standby

Correct Answer: A

A company has a regulatory requirement that all connections between their sites must be encrypted in a
manner that does not require maintenance of permanent tunnels. The remote offices are connected by a
private MPLSbased service that requires a dynamically changing key, spoke-to-spoke communication, and
reuse of the existing IP header. Which type of transport encryption must be used?
A. GETVPN
B. GRE VPN
C. Sandard IPsec VPN
D. DMVPN

Answer should be A: GETVPN (remote offices are connected by a private MPLS based service).

@ast

Eompls, VPLS are types of transport I agree with OTV.

@mdf @ast

I also agree

Eompls, VPLS are types of transport

OTV or ATOMGRE, the latter being “Any Transport over MPLS over GRE”, Cisco answer to this is OTV.

VXLAN is one to look out for, its the same as OTV but part of SDN or Overlay network design.

@ anonymous i agree with question 31 and 32 this how i answered.

A network engineer wants to segregate three interconnected campus networks via ISIS routing. A two-layer hierachy must be used to support large routing domains to aviad more specific routes from each campus network being advertised to other campus network routers automatically. what two actions should be taken accomplish this segration?(chose two)

A. Designate two ISIS routers as BDR routers at the edge of each campus
B. Assign similar router IDs to all routers within each campus
C. Designate tow ISIS routers from each campus to act as Layer 1/Layer 2 backbone routers at the edge of each campus network.
D. Assign a unique ISIS NET vale for each campus and configure internal campus routers with Level 1 routing.
E. change the MTU sized of the interface of each campus network router with a different value.

answer CD

b. Control plan traffic is prevented from traversing the OTV link
C. BPDUs are allowed to traverse the OTV link
D. data plan traffic is prevented from traversing the OTV link

ANS A: Unknown unicast flooding is suppressed over the OTV link

The OTV provides STP isolation, unknown unicast traffic suppression, and ARP optimization, to stop this traffic from traversing the DCI link (Data Center Interconnect).
*************************************************************
How does OTV provide STP isolation
A by using BPDU guard
B by using BPDU filering
C by dropping BPDU packets
D by using STP root optimation

STP isolation – OTV blocks BPDUs over the overlay, thus isolating each site in terms of spanning tree; an STP event in one site will not affect STP in another site. OTV edge devices send and receive BPDUs only on internal interfaces.
BPDUFilter would just not send BPDUs and ignore received one

ANS B by using BPDU filtering

i have C drop BPDU’s on this one ” No need to explicitly configure bridge data protocol unit (BPDU) filtering”

How does OTV provide STP isolation
A by using BPDU guard
B by using BPDU filering

D by using STP root optimation

The benefits of using OTV for Layer 2 extension include:

● No MPLS requirement

● No complex Ethernet over Multiprotocol Label Switching (EoMPLS) configuration for meshing

● No complex virtual private LAN services (VPLS) deployment for Layer 2 extensions

● Native spanning-tree isolation

◦ No need to explicitly configure bridge data protocol unit (BPDU) filtering

◦ Default isolation of spanning-tree problems to a given data center

Guys i dont know who this is not sure why they are using my handle
“silver097 at gmail dot com .” dont send your emails to this guy.

@MDF

Its says “How does OTV provide STP isolation” by the process is “BPDU filter”, yes you do not specifically configure it. OTV is configured at each side of the DCI link.
BPDUFilter does not send out of the interface, and drops any incoming. BPDU filter saving bandwidth because it not send it, so the other end will never drop a BPDU packet.

The same way if you enable TRILL or Fabric Path, it uses ISIS for the transport, but you do not configure ISIS specifically, just the command enable each technology and ISIS is configured behind the scenes.

So BPDU Filter, is already written and can be used on any switch, OTV uses BPDUFilter to make it happen, but you do not see it in config. I have four Nexus 7’s using OTV between two datacentres.

How does OTV provide STP isolation
A by using BPDU guard
B by using BPDU filering
C by dropping BPDU packets
D by using STP root optimation

Can it be say B: by using BPDU Filtering.
by default, does not transmit STP Bridge Protocol Data Units (BPDUs) across the overlay. This is a native function that does not require the use of an explicit configuration, such as BPDU filtering, and so on.

@ast contrats happy your second go proved useful. Thanks for the info, hope your time with me and mdf was useful

Congrats @ast hard work paid off took me two times as well
Did you see the Cisco live clip I posted about the OTV BPDU question
. Are you going for another test soon ? Which 1.

@at anonymous your up next :-) did you see the video do you agree with. Me on that question?

@MDF, not seen it yet, could not login to cisco dot com

Need help with a question guys..

An engineer is designing a network using RSTP. Several devices on the network only support legacy STP. Which outcome occurs?

We know that RSTP and STP interoperate, but I’m curious if anyone knows if fast convergence is achieved or not?

One dump says yes and Spoto dump says no..

@BOB

STP switch that peer with RSTP, uses STP metrics, RSTP that peers with STP switch uses STP metrics, so no.

@MDF

“Did you see the Cisco live clip I posted about the OTV BPDU question”

Ok I have watched it, the behavior is like BPDU filter, but the packet trace does show the BDPU is dropped, so I guess the correct answer is packet is dropped.

@anonymous thank you for taking the time to go look at this even though you passed. this will help clear anyone else;s doubt, about that question. are you taking another test soon?

@MDF scheduled in the next 2 weeks, subject to work schedule.

you can trust spotto dumps but ..they are expensive but worth every penny

Just got an email from back from {email not allowed}

They said that they have been receiving emails for over 6 months now asking for copies for dumps from things posted on DSTUT and RSTUT.

They said to never buy or pay anyone money on these sites. These are scammers.

If you don’t believe me, email them yourself. Makes sense since they never provided anyone in this forum with a copy of the dump.
