Three of the 515 questions in this pack

Question 1

Egress PE NAT is being used via a single centralized router to provide Internet access to L3VPN customers. Which description of the NAT operation is true?

  1. The NAT table contains a field to identify the inside VRF of a translation.
  2. Multiple address pools are needed for the same L3VPN because each site has a separate NAT.
  3. The different L3VPNs using the Internet access must not have IP overlaps internally.
  4. Users in different VRFs cannot share the same outside global IP address.
Show answer and explanation

Correct answer: A. The NAT table contains a field to identify the inside VRF of a translation.

In Egress PE NAT for L3VPN Internet access, the NAT translation table must maintain VRF context to distinguish which inside VRF a particular translation belongs to. This allows the centralized NAT router to properly handle traffic from multiple overlapping L3VPN customer address spaces by associating each NAT entry with its source VRF, enabling the same inside addresses to be translated differently based on their VRF origin.

Why the other options are wrong

  • B. Only a single address pool is needed per outside interface; multiple sites within the same L3VPN share the same pool.
  • C. L3VPN customers can have overlapping internal IP addresses because they are isolated within separate VRFs; NAT translation handles the overlap.
  • D. Different VRFs can share the same outside global IP address because the NAT table includes VRF context in the translation entry.

Question 2

You are writing an RPL script to accept routes only from certain autonomous systems. Consider this code: RP/0/RP0/CPU0:router(config-rpl)# if as-path in (ios-regex '.*77$') RP/0/RP0/CPU0:router(config-rpl-if)# pass RP/0/RP0/CPU0:router(config-rpl-if)# endif If you apply this code to BGP filters, which effect does the code have on your router?

  1. denies routes from AS 7070
  2. allows routes from AS 7077
  3. denies routes from AS 7007
  4. allows routes from AS 770
Show answer and explanation

Correct answer: B. allows routes from AS 7077

The regex pattern '.*77$' matches any AS path ending with 77. The .* matches any characters at the beginning, and $ anchors the match to the end of the string. The pass action accepts routes matching this pattern. Therefore, AS 7077 ends with 77 and matches the pattern, allowing these routes through.

Why the other options are wrong

  • A. AS 7070 ends with 70, not 77, so it does not match the pattern and is not denied by this rule.
  • C. AS 7007 ends with 07, not 77, so it does not match the pattern.
  • D. AS 770 ends with 70, not 77, so it does not match the pattern and is not allowed by this rule.

Question 3

Which regular expression query modifier function indicates the start of a string?

  1. +
  2. ^
  3. $
  4. [^]
Show answer and explanation

Correct answer: B. ^

The caret symbol (^) is the standard regular expression metacharacter that indicates the start of a string. When ^ appears at the beginning of a regex pattern, it anchors the match to the start of the string, ensuring that the following pattern must be found at the beginning.

Why the other options are wrong

  • A. The plus sign (+) is a quantifier meaning one or more occurrences of the preceding element.
  • C. The dollar sign ($) indicates the end of a string, not the start.
  • D. [^] is a character class negation operator, not a start-of-string anchor.

What makes the SPCOR hard

SPCOR is the carrier-grade core exam, and v1.1 is the version that dragged it into the SRv6 era. Segment routing is no longer a side topic: segment types, the SR control plane across BGP, OSPF and IS-IS, SR-TE, TI-LFA, PCE and PCC architectures, and SRv6 locators are all named in the blueprint, next to LDP sync and unified MPLS.

Networking is the biggest domain at 30%: IS-IS for IPv4 and IPv6, OSPFv2 and v3, the BGP path selection algorithm, routing policy language, IPv6 transition with NAT64, and high availability with NSF, NSR and BFD. Services covers EVPN, inter-AS VPN, carrier supporting carrier, Carrier Ethernet, L3VPN, and multicast with PIM-SM and SSM. Architecture reaches into 5G vRAN and ORAN transport, routed optical networking, NFV, and MACsec. Automation adds NSO, YANG, Ansible and Terraform, secure ZTP, and gRPC and gNMI with mTLS.
